Hello and welcome to episode 69 of The DX Mentor – A discussion with Jim, WB2REM. Thank you for joining us. I'm Bill, AJ8B.If this is the first time you are joining us, Welcome! We have a back catalog covering many aspects of DX. Please check us out. If you like what you find, please subscribe to always be notified of a new podcast!    Another way to keep in touch and to see what we are up to is via the DX Mentor Facebook page. I will be posting aboutupcoming podcasts as well as other DX events so please follow us.  Our guest today is Jim, WB2REM. Jim is an experienced, passionate operator and the conversation should be lively and informative.Here is the Mission Statement for this DXPedition: "In the spirit of the 7163/7156 MHZ DXGroup, this DXpedition was formed to provide the Amateur Radio Community with the opportunity of working the Faroe Islands on 6-160 Meters. We plan to be active on SSB, CW and FT8. We also hope to get to know the Amateur community in the Faroe Islands and when possible, explore the natural wonders of the islands, when not operating. Some members also plan to work SOTA and possiblyPOTA from the Faroe Islands." Jim and the team will be QRV from the Faroe Islands, June 1st to the 10th.Jim exhibited excellent patience when we were trying to schedule this podcast as we had to cancel twice. Unfortunately, the date that we finally agreed upon was adate that Joe had a personal conflict and could not be with us. Boy, did I miss him!Resources mentioned include:DXPedition Website - https://faroeis.com/7163 Net - https://7163net.com/Marlin Brandohttps://greylineperformance.com/blogs/news/famous-ham-radio-prepper-marlon-brando-fo5gj-tropical-south-pacific?srsltid=AfmBOop-SjYxYwMEvIhtp7VhxvI_Gzo0YQdI6M7d-JnJC4ZfMgShBZC3New World of Amateur Radio Videohttps://www.youtube.com/watch?v=LJDz2UlcY58Psychology of a QRMer - Page 13https://www.swodxa.org/wp-content/uploads/2018/04/Issue4_03012018A.pdfDX Cop - Page 11https://www.swodxa.org/wp-content/uploads/2018/05/Issue5_050118.pdfSouthwest Ohio DX Assoc. https://www.swodxa.orgDaily DX https://www.dailydx.com/DX Engineering https://www.dxengineering.com/Icom https://www.icomamerica.com/IC-905 https://www.icomamerica.com/lineup/products/IC-905/IC-9700 https://www.icomamerica.com/lineup/products/IC-9700/IC-7610 https://www.icomamerica.com/lineup/products/IC-7610/IC-7300 https://www.icomamerica.com/lineup/products/IC-7300/

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 8th of May 2025 Active region 4079 turned out to be not quite so bad as we had predicted. The sunspot was large, about ten times the width of our Earth, so we expected it to be more active. It was regions 4081 and 4082 that produced most of the flare activity last week. Two filament eruptions also occurred within two hours of each other. The first event began at 16:20 UTC on the 6th of May in the southern hemisphere and was responsible for a plasma wave across the surface of the Sun. The second filament eruption began in the northern hemisphere around 17:50 UTC to the northeast of AR 4079. A large amount of plasma was flung to the north. The filament eruptions on Tuesday, the 6th of May, did produce coronal mass ejections, but an Earth-directed component was not apparent. So we dodged a bullet! The solar wind speed remained high for most of last week which didn't help propagation. It did help to push the Kp index to five across the weekend of the 3rd and 4th of May. Things were more settled later in the week. On Thursday, the 8th of May, the solar wind speed was down to around 500 kilometres per second, the Kp index was three, but MUFs over a 3,000km path were still down at about 20 MHz. An Earth-facing coronal hole may add to the solar wind this weekend, the 10th and 11th of May. It looks like summer HF propagation is kicking in, with lower MUFs during the day but higher ones at night. Next week, NOAA predicts that the SFI will be in the range 155 to 165. Settled geomagnetic conditions are forecast for the beginning of this coming week, but unsettled geomagnetic conditions are expected for the 16th to the 19th of May. At that point, we could see the Kp index rise to five again, coupled with poorer propagation and reduced MUFs. And now the VHF and up propagation news from G3YLA and G4BAO Tropo has been a key propagation mode during the previous couple of weeks, but there have been variations in the location and timings of these conditions. Sometimes this will be due to increased moisture below the temperature inversion, so although the cloudier areas have been cool, they have probably done better for Tropo. This is due to the improved quality of the inversion, which performs better when there is a big moisture contrast across it, as you find with these layers of cloud.  Otherwise, we find that the better conditions are driven by night-time cooling, forming a low inversion near the ground which tends to disperse during the morning as the Sun warms it away. This should still be beneficial for the 70cm UK Activity Contest on Tuesday, the 13th of May, over eastern areas, but perhaps less so farther west. Good conditions will last into next week, but not everywhere. The main change will see an area of showery rain, possibly thundery, moving north into western Britain this weekend and perhaps some central areas early next week. This raises the prospect of some GHz band rain scatter in the west. The Eta Aquariids meteor shower peaked last week. In the decaying tail of activity, together with other lesser showers, this should keep an enhanced meteor input for the coming week. The Sporadic-E season typically runs from May to mid-September and the daily jet stream blogs have started on www.propquest.co.uk.  As usual, the main season offers two periods of activity, one in the morning and the second from late afternoon to the evening. Remember, Es is not guaranteed since it depends upon many factors, but jet streams help, and these are shown on the website maps. Use the map clusters to find out where any activity is starting on 10m and then follow it up in frequency through the lower VHF bands. EME path losses are at their maximum but falling after apogee on Friday, the 9th of May. Moon declination is negative, reaching a minimum this coming Thursday, so we'll have very short Moon windows and low peak elevation. 144MHz sky noise is moderate, increasing to high by next Friday. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 1st of May 2025 After the previous week's geomagnetic disturbances, as described in last week's GB2RS, the last seven days have been relatively quiet. The Kp index has mostly been in the ones and twos, however the rise to a Kp value of four on Thursday the 1st of May could herald a return to unsettled conditions. The solar flux index peaked at 170 on the 24th of April, before declining to 148 at the end of the month. HF conditions have been acceptable rather than outstanding and many stations struggled to work DX at times during International Marconi Day on the 26th of April. Nevertheless, there is DX about including ZS8W Marion Island, TX9A Austral Islands and HD8G Galapagos Islands. A look at the Proppy propagation prediction tool will help you work out the best times for making a contact with each station and on each band. You can find it by going to rsgb.org/propagation-tools Looking ahead, a large sunspot has rotated into view. Now designated 4079, this region has returned and was previously sunspot region 4055. It has already emitted an M-class solar flare, and we may expect greater activity as it becomes more Earth-centric over the next week. NOAA predicts that the solar flux index will climb again in the coming week, perhaps rising to between 160 and 165. Geomagnetic disturbances are also due to rise, with the Kp index forecast to reach five on the 5th and 6th of May. If this becomes a reality, expect lowered MUFs and poorer HF paths, especially over the poles as the Kp index rises. And finally, this week traditionally marks the start of the Sporadic-E season so keep an eye on 10m and 12m for short- and medium-range openings to Europe. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of high-pressure Tropo weather weakened a little as last week ended and we'll see the return of unsettled conditions with showery rain, perhaps even the odd thunderstorm. This is unlikely to lead to a total removal of high pressure and Tropo will still be worth looking for, especially over the western side of the UK. Some models place a new high just west of Britain during the coming week. This means that the rain prospects are not great, although probably just enough for a hint of rain scatter in any isolated heavier showers. The HF bands sounded a bit ‘watery' at times last week, which is a classic sign of potential aurora to explore on the higher bands. Look out for aurora in the coming week if the Kp index climbs above five. Meteor scatter is worth thinking about and, after last week's Lyrids, we now have the Eta Aquariids shower peaking in the early hours of the 6th of May. Remember that Sporadic-E ionisation is largely composed of long-lived meteor ions, so be on watch for Es openings. From now onwards through to mid-September, Sporadic-E will dominate the lower VHF bands, so check the clusters for signs of activity. Remember that Es starts on 10m and moves HF as an opening develops, even reaching 2m in the peak summer. Unlike Tropo, Es events are often fleeting, so the best you can do is monitor conditions as the Es intensifies and be ready when it reaches the band you want. Don't forget to check the daily Es blogs on www.propquest.co.uk which discuss the potential links between location of jet streams and Es formation. EME path losses are increasing, but apogee is still a week away. Moon declination passed maximum last Thursday so Moon windows are shortening along with reducing peak elevation. 144MHz sky noise is low all week. And that's all from the propagation team this week.

Foundations of Amateur Radio Over the years I've talked about different ways of using our license to transmit. I've discussed things like modes such as voice AM, FM, and SSB, and digital modes like FT8, WSPR, RTTY, FreeDV, Hellschreiber, Olivia and even Morse code. Recently it occurred to me that there is something odd about how we do this as a community. Now that I've realised this it's hard to unsee. Let me see if I can get you to the same place of wonder. Why is it that we as amateurs only use one such mode at a time? Let me say that again. With all the modes we have available to us, why do we only use one mode at a time, why do we get our brain into the mindset of one activity, stop doing that in order to move to another mode? It's weird. Amateur radio is what's called "frequency agile". What I mean by that is we are not restricted to a fixed number of channels like most, if not all other radio users. We can set our transmission frequency to whatever we want, within the restrictions imposed by our license conditions, and start making noise. There's agreement on what mode you can use where, but within that comes a great deal of flexibility. We have the ability to find each other. Call CQ and if the band is open and your station is transmitting a signal, the chance is good that someone somewhere on planet Earth will respond. We change frequency at will, almost without thought, but why don't we do this with modes? The closest I've seen is local VHF and UHF contests where you get different points depending on which mode you're using, and even that seems hard fought. It's weird. We have an increasing range of Software Defined Radios, or SDR, where your voice, or incoming text, can be transformed to a different mode at the touch of a button, but we rarely if ever actually use this ability. In case you're thinking that the restriction relates to the availability of SDR in the average amateur radio shack, most amateur modes fit within a normal audio stream and that same flexibility could be applied to the vast majority of transmitters scattered around the globe, but to my knowledge, it isn't. Why is that? Better still, what can we do about it? Can we develop procedures and processes to make us more, let's call it "mode agile", giving us the ability to change mode at the same ease as we change frequency? What would a "mode and frequency agile" amateur look like? What processes would you use? Right now the best we have is to QSY, or announce that we're changing frequency, but I've never heard anyone use that to describe a change of mode. Of course it's possible that I've led a sheltered life and not been on-air enough, but if that's the case, I'd love to hear about it. So, what is stopping us from becoming even more flexible? Do we need to practice this, develop better tools, teach new amateurs, have multimode nets, invent new modes that share information across different modes simultaneously, build radios that can transmit on different frequencies, or something else?

Foundations of Amateur Radio One of the basic aspects of being human and growing up is the process of learning. From a young age we explore our environment, play with others, have fun, fall over and bruise our knees, get up and try again. The playing aspect of this is often discussed as a way to keep things interesting. We add a competition element as an added incentive, so much so that we formaulate it into global competitions and call it sport. As a species it might surprise you that we spend about 1% of all Gross Domestic Product on sport, compared to science, which is about 2% of Global GDP. To give you some context, Agriculture accounts for about 4%, Manufacturing is 15%, Industry is about 26%, and Services account for roughly 62%. If you noticed that this is more than 100%, take it up with the World Bank, I'm a radio amateur, not an economist. Over the years I've explored different aspects of our chosen hobby of amateur radio. Time and again I return to experimentation, learning and having fun. Now I absolutely concede that my idea of fun and yours might not match, my GDP side quest is likely evidence of this, but in my opinion, this embodies the range of how we as a disparate community interact and exchange ideas across the ionosphere and closer to home using what we all can agree on is pretty close to magic. So, what is my point? Fair question. Having fun and learning. If you've ever had the opportunity to listen to aviation radio, and I'd encourage you to, the YouTube channel, VASAviation is a great place to start, comes with maps, explanations and subtitles. You'll discover that the complex domain of aviation communication is a dynamic environment where miscommunication matters and often has severe consequences. It's not all incidents and accidents though. If you look for Air Traffic Control legend "Kennedy Steve", you'll come across some of the funniest exchanges captured on ATC frequencies, all the while staying professional. So, how does this relate to amateur radio and you? Well, at the moment we have a few types of exchanges where we can practice our skills. The most obvious one is a thing we call contesting. A scored and rule bound activity where you're expected to exchange information and are declared the winner in a category. It's a little like sport and some have attempted to rephrase amateur radio contesting into a field that they're calling "radio sport". I have mixed feelings about this because there isn't much in the way of spectator activity associated with this. Another exchange is calling for DX contacts, sharing an exchange across distance, attempting to contact as many countries as possible, with the prize being membership into the fabled DXCC, the Century Club that acknowledges your prowess in making contact with a hundred countries. The most common exchange is the net or discussion group. It can be formal, like the weekly F-troop I've been hosting since 2011, or it can be ad hoc, one amateur chatting to another, sparking spontaneous discussion among several stations on frequency. We also do things like radio direction finding, someone sets up a transmitter and everyone playing tries to find the source as quickly as possible. First one to find it wins. It made me wonder if there are other things we might come up with. Has anyone played chess across HF? Or if you want to involve a larger group, what about playing Bingo! or a game of trivia? Anyone considered an MMORPG, or Massively Multiplayer Online Role Playing Game? The point being that we can play games, have fun, and learn in an environment where there are many factors affecting your ability to communicate, so we can all get better at keying the microphone and getting the message to the intended recipient. While we're having fun, nobody said that this needs to be a voice activity. An FT8 session could well be coerced into transmitting chess moves and nobody said that you have to do FT8 on the same frequency that WSJT-X is using. So, what games can you come up with and learn from? I'm Onno VK6FLAB

Using all modes on the 6m band, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of April 2025 We had a week of mixed solar conditions, but it ended with an SFI of 182 and a Kp of 3.67 on Thursday, the 3rd of April.   The geomagnetic field declined to quieter levels following a prolonged period of active, Kp4 conditions earlier on Wednesday due to solar wind enhancements. This impacted propagation, with the critical frequency struggling to get much above 7 MHz on Wednesday. Compare this with the following day, when the critical frequency hit 10.4MHz by 0830 UTC. Nevertheless, there was DX to be worked on Wednesday with FT8 allowing signals from Australia, Japan, Indonesia, China, and Surinam to get into the UK on 21MHz. The solar proton flux was also high on Tuesday, the 1st of April, affecting signals passing through the polar regions, but this had declined by Thursday and was heading back to normal levels. This was due to a large CME observed off the east limb of the Sun on Frida,y the 28th of March. If it had been Earth-directed, we may have seen a massive aurora. Next week, NOAA predicts that the solar flux index will stay in the 175-185 region. A Kp of six was forecast for yesterday, Saturday the 5th of April, followed by a further period of unsettled geomagnetic conditions due to an enhanced solar wind. If this is the case, we may not get more settled conditions until the 14th to the 16th of April. Nevertheless, this remains a good time for North-South HF paths, such as the UK to South Africa, and UK to South America. And now the VHF and up propagation news from G3YLA and G4BAO The old forecasting maxim that the ‘longer a high lasts, the longer it will last' is built upon the presence of blocked upper air weather patterns. When the jet stream gets so distorted into a high-amplitude north/south wave, its lateral movement, from west to east, becomes very slow. On the upper air charts, this takes the shape of the Greek letter omega, and this is the current set-up. It means that the weather associated with it also lasts a long time. In this case, it's the high pressure and its spell of fine weather that is likely to last for the whole of the coming week. The position of the high will change, though, starting over the North Sea and ending over the UK and the nearby Atlantic. This means that Tropo will be the mode of choice for the coming period, which includes the 70cm UK Activity Contest on Tuesday and the 6m UK Activity Contest on Thursday. Rain scatter is unlikely during this extended period of dry weather. The meteor scatter options are still mainly driven by random meteors for the coming period into next week, but the next important shower, the Lyrids, peaks on the 22nd of April. The auroral alerts continue to come through, raising interest. As usual, the clue will be fluttery-sounding signals on the bands, particularly noticeable on CW, but they can also be pronounced on speech transmissions. Monitor the Kp index for values above Kp5. There have been a few trans-equatorial openings to Southern Africa on 50MHz digital modes for the fortunate few who live in the extreme south and southwest of the UK, but it did extend up to Cambridgeshire and Suffolk briefly on some days last week. The long drought of Sporadic-E will soon be over, but we're still in the realms of very isolated events for 10m and 6m, which will be short-lasting. The jet stream, which can be a good clue as to potential locations, suggests looking to Scandinavia, the Baltic and northern Europe. EME path losses are falling again, but Moon declination has been at its highest this weekend, so we have long Moon windows. 144MHz sky noise is low throughout the coming week. And that's all from the propagation team this week.

SP stations also send their province code.  Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 27th of March 2025 Last week's space weather was dominated by a large coronal hole on the Sun. This was probably one of the largest we have seen for many years. Moderate, G2, geomagnetic storming was observed following the arrival of a solar wind stream from the hole, with the wind speed exceeding 600 km/s on Wednesday, the 26th. This pushed the Kp index to 6.33, depressing the MUF slightly. Luckily, the daytime MUF over a 3,000km path mostly stayed above 28 MHz, but it was slow to rise on Thursday, the 27th, when it took until 0900 UTC to reach 28 MHz. At the time of writing, the solar wind speed was more than 800km/s, so we can expect more disruption until at least Saturday, the 29th. Meanwhile, the solar flux index declined to 152 by Thursday, the 27th, with only four small sunspot regions visible. CDXC members have been discussing working New Zealand in the morning at the ZL sunset, often on low power. Listen and look for ZL4OL and ZL2CC, usually on FT8, but if conditions allow CW and SSB. 20m or 40m seems to be the favourite, and the VarAC data mode seems popular in ZL as well. Next week, NOAA predicts the solar flux index will climb again, perhaps to 180 by the 4th of April. However, unsettled geomagnetic conditions are forecast again, beginning on the 3rd. We may expect the Kp index to reach six, which could be the start of at least ten days of disruption. And now the VHF and up propagation news from G3YLA and G4BAO The overall picture for the weather patterns in the coming week is that of high pressure, which means that Tropo should be available as a good mode for VHF bands. There can be quite strong temperature inversions in the region of large well-developed areas of high pressure. The best performance will usually be around the edges of the high where the height of the inversion and ducting layer is typically between 0.5km and 2km above the ground, and can cover large distances for excellent DX prospects. Occasionally, a shallow ducting layer can form near the ground overnight but often disperses by mid-morning. If you are in a good inversion region, try SSB or CW on the VHF/UHF bands, as paths of up to 1,500km can often be achieved from a good ‘tropo lift'. The reverse side of the high-pressure systems is that we will have low pressure nearby, mainly to the north and west of the UK. Any potential for rain scatter will mainly be over northwestern Britain, although an active front that was moving south on Friday, the 28th of March, was a good candidate for chance rain scatter on the GHz bands. The prospects for meteor scatter are still largely dependent upon random meteors, which are usually best in the hours before dawn. Current solar activity will continue to trigger auroral alerts in the coming week. Now onto Sporadic-E, and last week we had a few out-of-season isolated foEs ‘blips' to between 5- 7 MHz, which was enough to produce propagation on 10m and 6m, albeit very fleetingly. There have already been some equinox-related 6m trans-equatorial propagation or TEP workable from the Southern part of the country, so keep an eye open late morning for Africa and late afternoon for South America.  EME path losses have continued to improve until perigee this morning, the 30th of March. Moon declination is still falling, and reached a minimum last Friday, the 28th. Moon windows will increase throughout the coming week. 144MHz sky noise is low, apart from Saturday the 29th when the Sun was close to the Moon in the sky, rising to moderate next Thursday before dropping back to low for the weekend. And that's all from the propagation team this week.  

GB2RS News Sunday the 23rd of March 2025 The news headlines: The RSGB launches its new web app RSGB Elected Board Director unopposed candidates are announced Full details of the RSGB 2025 AGM have been released The RSGB is excited to give you a first look at its new app!

Both were interviewed separately to enable RSGB members to hear their views on the current issues facing amateur radio and the Society. Their answers were combined into two videos: the first ‘short' video is just two quick questions, and the second video is a more in-depth interview. You can watch them both on the RSGB website and its YouTube channel. For more information about each of these unopposed candidates, see the April 2025 issue of RadCom or go to rsgb.org/candidates The RSGB 2025 AGM will take place at 10 am on Saturday the 12th of April. The event will be held online to ensure that as many members as possible can watch and take part. The formal business of the meeting will include the results of members' votes on the resolutions and details about the election. The RSGB President John McCullagh, GI4BWM will give a video review of 2024, and the Society will announce the recipients of its annual awards and trophies, as well as the winners of its construction competition. You can ask the Board questions on the day via Zoom or the YouTube live chat, or by submitting a written question in advance. After the main AGM meeting, the RSGB is delighted to have a presentation about the Society's strategy. Led by Board Director Mark Jones, G0MGX, there will also be contributions from Board Director Ben Lloyd, GW4BML; Spectrum Forum Chair Murray Niman, G6JYB; and Bob Beebe, GU4YOX who will at that point be the new RSGB President.

After the disturbed geomagnetic conditions on the 12th to the 14th when the Kp index rose to five, conditions were a little more settled. The solar flux index hit 204 on the 17th of March but then declined back to the 180s. Having said that things were settled, the Kp index did exceed four for three periods on the 19th, peaking at 4.67. This had the effect of reducing the MUF over a 3,000km path to 21-24MHz. We also had two M-class solar flares on the 17th and the 19th, with the latter causing a coronal mass ejection that may give Earth a glancing blow around the 22nd of March. As spring progresses, we may find the F2-layer MUF dropping as we move to summer ionospheric conditions, perhaps to be replaced by enhanced sporadic-E conditions on 10 metres instead. Next week, NOAA predicts that the solar flux index may drop further, perhaps hitting 150 on the 28th. Unsettled geomagnetic conditions are forecast for the 25th to the 28th, with a maximum Kp index of five. As we said last week, this is now a peak period for auroral activity, given the angle that the Earth makes with the Sun. The 'Russell-McPherron' effect is down to the alignment of the Sun and Earth around the spring and autumn equinox and means that you are twice as likely to experience the aurora in spring and autumn than in winter and summer. And now the VHF and up propagation news from G3YLA and G4BAO The recent fine weather has provided some useful Tropo. This has been mainly towards the east and into the near continent, which seemed like nice timing for the 1.3GHz UK Activity Contest last Tuesday evening. Despite this, many participants reported conditions as poor. The high is now moving away and by the time you hear this, it will be a predominantly low-pressure weather sequence from now on. This means limited Tropo in the coming week, and rain scatter comes to the fore as a mode of choice if you have a GHz band set up. The solar conditions continue to provide a trickle charge of auroral alerts, but not enough for any significant operating advantage. As usual the message is to keep on top of things by monitoring the Kp index for values over 5. Meteor scatter remains largely in the gift of random meteors, so it's an early start to catch the pre-dawn peak of random meteors if you are so persuaded. Lastly, a mention of Sporadic-E which is still in its close season. We have a while to wait until later next month when we could expect the occasional stirrings on 10m. EME path losses continue to improve until the Moon's perigee (its closest point to Earth) on the morning of the 30th of March. Moon declination has been falling, reaching a minimum yesterday, the 22nd. So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise started high on Friday the 21st of March but will drop back to low by the middle of next week. And that's all from the propagation team this week.

GB2RS News Sunday the 16th of March 2025 The news headlines: Final chance to get involved in British Science Week and share your activities Advance notice of how to ask the Board questions at the RSGB AGM The RSGB has launched new National Radio Centre web pages Today, Sunday the 16th of March is the last day of British Science Week 2025.

Using all modes on the 4m band, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of March 2025 We've had another week of disturbed geomagnetic conditions with the Kp index at four or five for long periods. On the evening of the 12th of March, Kp was five and, at the time of writing, has stayed there for a total of five three-hour periods. This has taken its toll on the ionosphere with MUFs over a 3,000km path down to less than 24.7MHz during daylight. Meanwhile, the solar flux index rose to 160 on Thursday the 13th after hitting a low of 147 on the 7th. The best HF propagation was last weekend, the 8th and 9th of March, just in time for the Commonwealth Contest. This saw stations around the world romping into the UK, including signals from Australia, New Zealand, the Falkland Islands, Barbados, and many others. As contacts were limited to Commonwealth countries, it meant the UK had little QRM to contend with and it was fairly easy to fill the log book on 40m to 10m. Australia was still coming in at 59 after dark, and even British Columbia on the west coast of Canada could be worked with simple wire antennas and low power. This may have been caused by a pre-auroral enhancement, as the Kp index rose late on the first day of the contest. Next week, NOAA predicts the solar flux index may rise to 195 by the 21st. It also suggests that we may be back into calmer geomagnetic conditions with a maximum Kp index of two. This will be a welcome change and, if it happens, will no doubt result in better HF conditions. And remember, March is a good month for north-south contacts, such as the UK to South Africa and the UK to South America. But with the equinox just around the corner, auroras are twice as common due to the Russell-McPherron effect. Just as when two bar magnets attract one another when they are oriented oppositely, so opposite Bz components attract. During the autumn and spring equinox, this orientation enables a 'connection' to the Sun, thereby allowing the solar wind to stream in. And now the VHF and up propagation news from G3YLA and G4BAO The recent change to colder weather brought showers and potential rain scatter to the second half of last week. But this weekend we have lost the showers and gained a large region of high pressure to bring a hint of Tropo. It's not perfect, since in cold air highs like this, conditions are usually less than ideal, so don't expect too much from this particular area of high pressure.  The high will last until midweek before it slips away into eastern Europe and, on its parting, may allow some moisture below the inversion and will improve the Tropo prospects briefly. The second half of the coming week will be dominated by low pressure and back to rain-scatter as an option on the GHz bands. The solar conditions have continued to provide a few weak auroral alerts and it's worth continuing a watching brief on the Kp index for hints of activity; anything greater than a Kp of five is worth our interest. Listen out for watery-sounding signals on the LF bands and then check out the 10m and 6m bands for auroral signals. The next important meteor shower is the April Lyrids, but there's always the chance of random meteor scatter activity, particularly in the pre-dawn hours. It's still a little early to mention Sporadic-E, but it's always worth looking at the lower frequencies first, which means 10m and 6m. Check the graphs on Propquest for signs of spikes in the foEs, which is the critical frequency of the Es-layer. EME path losses continue to rise until apogee on Monday evening. Moon declination is still falling, reaching a minimum on Saturday the 22nd. So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise is moderate and rising to high by Friday the 21st. And that's all from the propagation team this week.

Hello and Welcome to the DX Corner for your weekly Dose of DX as part of Ham Radios oldest Ham Radio Magazine on the air, “This week in amateur radio.” I'm Bill, AJ8B. I am not sure how many of you are interested in 60M, but overall interest is growing. One of my best friends, Joe, W8GEX, produces a 60-meter newsletter. Joe is considered by many as the godfather of 60m. With almost 250 entities confirmed on 60, I can understand why. New Zealand stations ZL4OL and ZL2CC have been heard around 0700z. Watch your 60m packet cluster for these advid 60M operators. 4U1UN has been on 60m recently. Keep an eye out for that one also. Some of the rare DX on 60 meters recently has included A51AE, 7Q6M, and T77C.Don't forget to have a look at our website 60metersonline.com. There are details about our DXCC and WAS Awards for 60 meters. . Thanks, Joe, for letting me use this information.

SCRIPT:Amateur Radio Newsline Report 2471 for Friday, March 7th, 2025 Amateur Radio Newsline Report Number 2471 with a release date of Friday, March 7th, 2025 to follow in 5-4-3-2-1.The following is a QST. A survey reveals some important trends in Brazilian amateur radio. Huntsville's new museum of communications and technology is open -- and the founder of the Hurricane Watch Net becomes a Silent Key. All this and more as Amateur Radio Newsline Report Number 2471 comes your way right now.** BILLBOARD CART**SURVEY GIVES DETAILED SNAPSHOT OF HAM RADIO IN BRAZILPAUL/ANCHOR: Our top story takes us to Brazil where a recent survey is providing a detailed look at trends among hams in South America's largest nation. Jeremy Boot G4NJH shares some of its findings.JEREMY: An important snapshot of the state of amateur radio in Brazil has provided the national ham radio society and the telecommunications regulator with insights into relevant trends. The sampling of 940 hams in 27 states and 350 cities was conducted in May of 2024 by Guillermo Crimerius, PY2BIL, a member of the board of the Sao Paulo chapter of LABRE, the Liga de Amadores Brasileiros de Rádio Emissão. Guillermo told Newsline that the findings are also being shared with the regulator ANATEL.He said that the findings held no surprises but many details were nonetheless significant. Brazil's ham radio community remains predominantly male, with women comprising only 2 percent of the hobby. Survey results also showed that hams are an aging population in Brazil: 72% are between 40 and 70 years old, with most of them between 40 and 60. While new licensees continue to join Brazil's ham community every year, there is low membership in clubs and associations, giving little opportunity for the networking and skills training usually provided by them. Guillermo writes: [quote] "This scenario has had an impact on new generations of hams,who face difficulties in learning the essential technical matters and especially the operational and cultural activities." [endquote]For a full copy of the report, which is downloadable, visit the link in the text version of this week's newscast at arnewsline.orgThis is Jeremy Boot G4NJH.(GUILLERMO CRIMERIUS, PY2BIL)**NOMINATE THE NEXT "YOUNG HAM OF THE YEAR"PAUL/ANCHOR: We remind our listeners that young hams who live in the continental United States have an opportunity to make news, if they aren't already doing so, by being a recipient of this year's Amateur Radio Newsline Bill Pasternak Memorial Young Ham of the Year Award. Consider nominating an amateur radio operator 18 years of age or younger -- someone who has talent, promise and a commitment to the spirit of ham radio. Find application forms on our website arnewsline.org under the "YHOTY" tab. Nominations are now open. We are accepting nominations through May 31st.**BRANDMEISTER DMR PHASING OUT SOME RADIO IDSPAUL/ANCHOR: Certain Radio IDs that have been in use on the Brandmeister DMR network are going away later this year. Sel Embee KB3TZD explains.SEL: The Brandmeister DMR network has announced that it is phasing out its support of certain Radio IDs that do not comply with the Mobile Country Code, or MCC, numbering system. This means that by June, radio operators with certain DMR IDs will need to request new numbers to be assigned to their radios. The first phase of these changes will begin on the 1st of June, when Brandmeister will stop supporting five-digit CAP+ IDs. Starting on the 1st of January, 2026, radios with seven-digit personal radio IDs that begin with the numeral 1 will also stop working on the network. In making this announcement, Brandmeister assured repeater operators that it will continue indefinite support of repeaters that have six-digit radio IDs.Brandmeister said in its announcement in late February that this an effort to address improperly numbered Radio IDs – something Brandmeister has been trying to contain for seven years. It said on its website: [quote] The Brandmeister DMR platform is a constantly evolving system, requiring regular optimizations and maintenance to ensure its efficiency, reliability, and alignment with global open standards.” [Endquote]New IDs can be obtained through Radio ID (Radio Eye Dee) dot net (Radioid.net).For further instructions visit the Brandmeister link that appears in the text version of this week's newscast at arnewsline.orgThis is Sel Embee KB3TZD.[DO NOT READ: news.brandmeister.network](NEWS.BRANDMEISTER.NETWORK, AMATEUR NEWS DAILY)**3 IRISH "KILMOLIN CLUSTER" BEACONS GO QRT TO RELOCATEPAUL/ANCHOR: A trio of beacons in Ireland have been taken out of service in preparation for being moved, as we hear from Jeremy Boot G4NJH.JEREMY: In Ireland, three beacons that have been operating from a site south of Dublin have gone QRT to allow for their relocation. The EI4RF, EI1KNH and EIØSIX beacons have been part of what is known as the Kilmolin cluster. They had been hosted by Paddy Geoghegan, EI5HS, who became a Silent Key last year.The beacons, which have a new owner, went off the air in mid-February and are expected to slowly come back. According to reports on groups.io and the SWLing Post blog, the EI4RF 4-metre beacon is expected to be the first to return, perhaps by May just as sporadic-E season begins. The EIØSIX beacon is expected to follow sometime afterward on 6-metres. It was unclear how and when service will be restored on the EI1KHN beacon, which operated on 40 and 60 MHz. It is also unclear whether this beacon will need to be assigned a new callsign.This is Jeremy Boot GF4NJH.(EI7GI BLOG, QRZ.COM, SWLING POST)**UNIVERSITY IS W. BENGAL'S 1ST TO HAVE HAM CLUB STATIONPAUL/ANCHOR: Students and faculty in India are celebrating the establishment of the first state-of-the-art shack on a West Bengal state university campus. Graham Kemp VK4BB tells us more.GRAHAM: Aliah University, a state university that created for the education of many of India's minority populations, is about to become the first university in West Bengal with its own state-of-the-art ham radio club station.The announcement was made in late February in connection with a seminar held on the Kolkata campus introducing students and faculty to various aspects of amateur radio. The one-day session, held on the 24th of February, covered emergency communications and radio technology and included hands-on experience for the estimated 250 attendees. It was led by members of the West Bengal Radio Club, the Indian Academy of Communication and Disaster Management and organized by the school's Department of Electronics and Communication Engineering. A number of other schools have hosted similar amateur radio workshops throughout the region, which is a coastal area subject to violent storms and other natural disasters that rely on alternate forms of communication.

One traditional event will be missing from this year's show, however: There will be no separate reception for amateur radio operators.Hams, of course, are still welcome. Indeed, many broadcast professionals - especially those on the engineering side - enjoy an active and robust time on the air on the amateur bands. A posting on the Radio World website said that this year's ham reception was not on the schedule. The reception had been hosted for a long time by Bob Heil K9EID, who became a Silent Key last year.The article said that organizers are hoping to [quote] "reinvent the event for next year by exploring fresh partnerships and innovative ideas." [endquote]In the meantime, licensed hams who work in the industry can still look forward to the usual opportunities for networking and learning about new technology.

We learn more from Jason Daniels VK2LAW.JASON: It's still early in the game for the newly organized not-for-profit DX India Foundation but the team has already announced ambitious plans to increase India's presence on the DX map. As part of its mission to activate rare IOTA islands, conduct DXpeditions and provide DX and POTA chasers with a chance to work different entities in India, the team has its sights set on Arnala Island, IOTA number AS-169, which is near Mumbai. According to an announcement from the team, the island has had no amateur radio activity since 2006. Hams from the DX India Foundation have applied to use the callsign AU2M and hope to be on the air from the 29th of May through to the 1st of June. Later plans include a 10-day adventure to the Lakshadweep archipelago off the coast of Kerala [CARE-ruh-luh] in southern India.The DX India Foundation has also established an online forum in groups.io to encourage a sense of international community for chasers and activators. In between trips, the foundation's activity will be focused on training and mentoring other radio operators.This is Jason Daniels VK2LAW.(DX INDIA FOUNDATION)**HUNTSVILLE'S ‘SIGNALS' MUSEUM OPENS IN ALABAMAPAUL/ANCHOR: Huntsville, Alabama, home of the Huntsville Hamfest, has a new way to celebrate technology and, of course, amateur radio. To welcome the museum and honor the spirit and advancements made in technology, Newsline is departing from the norm this week. This report is being read via artificial intelligence and a correspondent known as AI-Drew.AI-DREW: On March 1st, the SIGNALS Museum of Information Explosion opened its doors to what founders hope will be an immersive and hands-on environment for visitors. The museum, housed a short drive from where the Huntsville Hamfest is held each year, has an array of exhibits devoted to communications technology in all its forms throughout history. Amateur radio operators who are visiting will be particularly interested in the ham shack, a welcoming space for regional radio clubs and other radio operators to meet or work on building equipment. The museum also has an on-site radio tower.Whether you live in the area or plan to visit Huntsville this year, the museum will welcome you. Visit their website at signals hyphen museum dot org.

He has become a Silent Key, as we hear from Randy Sly W4XJ.RANDY: It can be said that the seeds of the Hurricane Watch Net were planted in 1965 as Hurricane Betsy raged its way through the Bahamas, making landfall in the US that September. Gerald Murphy, K8YUW, who was stationed by the US Navy in Rhode Island at the time, was also handling messages and phone patches for the Intercontinental Amateur Radio Net. When hurricane-specific traffic started to overwhelm the regular net's messages on their 20m frequency, Gerry suggested that those messages be handled 5 kHz higher. Marcy Rice, KZ5MM, who was in the Panama Canal Zone QSY'd with him up to 14.325 MHz and that was the genesis of the Hurricane Watch Net.The net has become the backbone of a robust communications system during storm season. Trained hams share advisories, data and post-storm damage information in affected areas with national hurricane centers in the US and, when needed, Canada.Gerry, who became a Silent Key on the 25th of February at the Ohio Veterans Home in Sandusky, leaves behind this vibrant legacy. He served as net manager from September of 1965 until February of 1988, staying on afterward as assistant net manager. Health issues compelled him to retire from the net in March 1991.The Hurricane Watch Net has been planning an on-air special event in September to mark its 60th anniversary. Net manager Bobby Graves,KB5HAV, told Newsline [quote] "I was hoping and praying Jerry would make it to see his creation's 60th Anniversary this coming Labor Day....We will endeavor to make it even more special." [endquote]Gerry was 88.This is Randy Sly W4XJ.(BOBBY GRAVES, KB5HAV; EDDIE MISIEWICZ, KB3YRU)**WORLD OF DXIn the World of DX, Chris, WA7RAR, is on the air until the 16th of March from Barbados, IOTA Number NA-ØØ21. He is using the callsign 8P9CB, operating SSB and CW on 20-10 metres. Some of his locations are POTA sites.

We'll let Jim Meachen ZL2BHF explain how it happened.JIM: If you've ever wondered whether Echolink is a viable mode for teaching or learning CW, just ask Ted ZL1BQA, who is proud to have logged a respectable number of CW contacts during the recent Jock White Memorial Field Day in New Zealand. Studying CW for almost a year with the Franklin Amateur Radio Club, Ted was able to restart his long-ago code skills in sessions led by the club president Peter Henderson ZL1PX. It was done over Echolink.Ted had enrolled last May along with three younger members who were first-time learners - Francois, ZL4FJ, Steve, ZL1TZP and Steve ZL1SPR. With only Ted able to copy Peter's signal over HF, the club followed a suggestion made by Gary ZL1GAC: try Echolink, a computer-based ham radio mode that incorporates VoIP technology. Loading CW software onto his computer, Peter was able to send the code intended for each session, confident that everyone had an equal chance of copying clearly.Weekly sessions soon expanded to twice a week as the students concentrated on letters, then numbers - and eventually basic punctuation.After a break in the action, the club is back on Echolink with CW sessions three nights a week. As for Ted, he's on a roll. Peter told Newsline in an email that he has resumed making CW contacts on a daily basis on HF using the Vibroplex that once collected dust instead of QSOs.This is Jim Meachen ZL2BHF.(QUA, Peter Henderson, ZL1PX)**Have you sent in your amateur radio haiku to Newsline's haiku challenge yet?

Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report, serial number and time. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 6th of March 2025 We started last week with geomagnetic disturbances that saw the Kp index rise to a maximum of 5.67 on the 28th of February and then hover around the 4.5 mark for the next couple of days. As predicted, the rest of the week went quite well, with the Kp index in the range of one to four. The solar flux index fell from a maximum of 210 on the 23rd of February to a low of 140 on the 2nd of March. It then climbed back to 160 on the 4th. Over the past week, we have had no X-class and only one M-class solar flare which was on the 5th. As we head into next week, it looks like all the sunspots in the Sun's northern hemisphere have now departed. Nevertheless, the southern hemisphere is still supplying lots of spots so don't panic just yet! HF conditions have been quite good. VK6IF and VK6IA in Western Australia were booming in on 28MHz USB on the morning of Thursday the 6th, as was VK9CU on the Cocos-Keeling Islands. Nigel, VP8TXF and Ian, VP8CIW have been operating from the Falkland Islands ahead of this weekend's Commonwealth Contest and have been worked from the UK on 20m-10m. They are there until the 10th, so get in quick. Other DX to be worked this week includes VU4AX Andaman Islands, 6Y7EI Jamaica, PJ7AA Sint Maarten Island, 4S7KKG Sri Lanka, TY5C Benin, 6W7/ON4AVT Warang Senegal, RI1ANE Antarctica and H44MS Solomon Islands. Next week, NOAA predicts that the solar flux index will start off around 150 and may then climb to 185 by the 16th. A large coronal hole became Earth-facing on the 6th, which may result in unsettled geomagnetic conditions this weekend, the 8th and the 9th. It looks like we can expect unsettled geomagnetic conditions around the 10th to the 16th, with a maximum predicted Kp index of five. And now the VHF and up propagation news from G3YLA and G4BAO The weather divides into two segments; the first, from the middle of last week through to the middle of next week, is rather changeable with low pressure nearby bringing rain or showers and potential for rain scatter on the GHz bands. Eventually, the unsettled weather ends with a cold northerly on Tuesday the 11th and this leads to a new high building from Wednesday into the weekend of the 15th and 16th March.  This is good news for Tropo and could possibly be of benefit to those in the UK 70cm Activity Contest on Tuesday the 11th in the western UK, but more generally for the FT8 70cm Activity Contest on Wednesday and the 50MHz UK Activity Contest on Thursday evening. We are still between major meteor showers and therefore must rely upon random activity for now. The next shower of note is the Lyrids on the 21st and the 22nd of April, so we have a while to go yet. The solar activity has continued to produce a regular supply of auroral alerts and fluttery signals on the LF bands, but with a lot of clouds in northwestern areas and southern parts just marginally out of reach for any naked-eye auroras. A few digital camera pictures did surface on the web.  Keep an eye open just in case though. Remember Kp equalling five or greater is where we need to be. Lastly, the Sporadic-E prospects are still relatively low with only the odd minor blip up to around a Sporadic-E critical frequency of 5 to 7MHz, often around the middle of the day. This contrasts with the morning and evening windows in the main season. It is enough to promote interest in the 10 or 6m bands, but almost certainly a fleeting moment. EME path losses rise all this coming week and moon declination falls with associated shortening Moon windows and reducing peak Moon elevation. The best results will therefore be early in the week. 144MHz sky noise is moderate this weekend, falling to low in the week commencing the 10th. And that's all from the propagation team this week.

More information is available on page 83 of the February 2025 issue of RadCom or via rsgb.org/careers  If you are interested in applying for the role, email radcom@rsgb.org.uk The Commonwealth Contest is a unique annual event which has run every year since 1931. Held over the weekend nearest to Commonwealth Day, it is loved by many RSGB members and radio amateurs throughout the Commonwealth. In 2024 over 240 individual entrants and 15 Commonwealth Headquarters stations representing national societies were active. The Commonwealth Contest is a treasure hunt with amateurs in distant locations looking to make a QSO with you, so if you are not a regular contest participant or you have a simple HF setup, you might use the Contest as an opportunity to make DX QSOs. UK amateurs are travelling to the Caribbean, the Falklands and New Zealand, so your scope for QSOs is expanded, and many VK, ZL, VU and VE amateurs will be joining in too. This year the Contest takes place on the 8th of March, and you can find out more on page 38 of the March issue of RadCom and on the RSGB website via tinyurl.com/commonwealth-contest On Saturday the 29th of March, the RSGB National Radio Centre Coordinator, Martyn Baker, G0GMB, together with Andy Webster, G7UHN from the Radio Communications Foundation, will be delivering a talk in the Fellowship Auditorium at Bletchley Park. It will introduce people to the radio spectrum and how to get to grips with the fundamentals of radio transmission. The RSGB is delighted that its members can benefit from a 10% discount, reducing the price to £14.40. To find out more, go to the ‘What's on' section on the Bletchley Park website via bletchleypark.org.uk  If you'd like to visit the wider Bletchley Park site after the talk, RSGB members can gain free entry by downloading a voucher from rsgb.org/bpvoucher Amateur Radio Clubs On The Air is getting ready for a second weekend of operating on the 22nd and 23rd of March.

The Commonwealth HQ stations will also send ‘HQ' as part of the contest exchange.   Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 27th of February 2025 We had another week of mixed geomagnetic conditions. The Kp index rose to a high of five with visible aurora over the UK at times. Two large coronal holes are now both facing Earth. A solar wind stream flowing from these zones is expected to flow past Earth, possibly on Friday the 28th of February or Saturday the 1st of March. Active geomagnetic conditions with a Kp index of four are currently forecast for this weekend. There has also been more solar flare activity over the past seven days with an X2-class flare on the 23rd and ten M-class flares. The X-class flare occurred at 19:27UTC so had little effect in Europe as the Sun had set. Luckily, an associated coronal mass ejection was not Earth-directed. Another fast-moving CME on the 24th was also not Earth-directed. As we enter March it looks as though the Sun is still very active. The solar flux index stood at 180 on Thursday the 27th, after hitting 210 on the 23rd. Maximum usable frequencies over 3,000km are still reaching 34-35MHz around midday, while night-time MUFs are generally around 10-11MHz, with occasional openings on 20 metres. This week Bob, VP8LP on the Falkland Islands has been active on 10 metres SSB and has been worked from the UK. As we enter March this is a good time for North-South paths on HF, such as UK to South Africa and UK to South America. The spring equinox is also a good time for auroral conditions. NOAA predicts the Sun will start next week with an SFI of 190, perhaps falling to 170-180 as the week progresses. We hesitate to say this, but geomagnetic conditions are predicted to be good once we get past the disturbances on the 28th and the 1st, but only time will tell! And now the VHF and up propagation news from G3YLA and G4BAO There is likely to be a welcome return of high pressure for much of the period from this weekend until the middle of the coming week on the 5th of March. Models show a return of unsettled Atlantic weather, meaning lows, fronts, showers and rain scatter for the GHz bands. Until then, it will be typical high-pressure Tropo conditions with an extensive temperature inversion aloft caused by the descending warming air in the high-pressure region. This should provide ducting conditions over a large part of the country. As often, the far north of the UK will probably just miss out and retain too much breeze for the inversion to be effective. The lull in meteor shower activity continues, so once again your best chances will be in the morning hours around, or just before, dawn. The Sun has kept aurora seekers busy and shows how frequently it can just tip into the right disturbed conditions at this stage of the solar cycle. As we said earlier, there have been reports of visible aurora in the past week. The signs for this are the Kp index rising to five or greater and flutter on LF band signals or trans-polar paths on the HF bands. The new Sporadic-E season is almost upon us, but we are not there yet. Check the graphs on Propquest for signs of enhanced foEs values and check the HF bands first; 10m is particularly good for strong European Es signals. EME conditions will be predictable as usual, with Moon declination rising all week and path losses at their minimum at perigee late on Saturday the 1st of March. 144MHz sky noise is low from this coming weekend, rising to moderate by Friday the 7th. And that's all from the propagation team this week.

Foundations of Amateur Radio Recently I received a lovely email from Michele IU4TBF asking some pertinent questions about the Bald Yak project. If you're unfamiliar, the Bald Yak project aims to create a modular, bidirectional and distributed signal processing and control system that leverages GNU Radio. The short answer to how I'm doing getting GNU Radio to play nice with my computer is that I have bruises on my forehead from banging my head against the wall. When I get to success I'll document it. To be clear, I'm not sure what the root cause is. I suspect it lies between the GNU Radio developers, the people making packages and the manufacturer of my computer. I'm the lucky one stuck in the middle. A more interesting question that Michele asked was, for Bald Yak, what is the A/D and D/A requirement for making GNU Radio talk to an antenna? This is a much deeper question that meets the eye and I think it serves as a way to discuss what I think that this project looks like. Ultimately in the digital realm, to receive, an analogue antenna signal needs to be converted to digital using an Analogue to Digital or A/D converter, and to transmit, the reverse uses a Digital to Analogue or D/A converter to make an electrical signal appear on your antenna. The specific A/D or D/A converter determines what you can do. The sampling rate of such a converter determines what frequencies it can handle, the sample size determines the range of signals it can handle. You can compare it with a video screen. The sample rate determines how many pixels on the screen, the sample size determines how many colours in each pixel. The sample rate of an A/D converter is measured in samples per second. If the device only has one channel, you could think of this as Hertz, but if there are multiple channels, like say a sound-card, the sample rate is likely equally divided across each channel. You might have a sound card capable of 384 thousand samples per second, or kilo-samples, but if it supports simultaneous stereo audio input and output, only 96 of those 384 kilo-samples will be allocated to each channel and only half of those will actually help reconstruct the audio signal, leaving you with 48 kHz audio. In other words, the advertised frequency response might not have a direct and obvious relationship with the sample rate. At the moment I have access to a few different A/D and D/A converters. The simplest one, a USB audio sound card, appears to do up to 192 kilo-samples at 16 bits. The next one, an RTL-SDR tops out at a theoretical rate of 3.2 million or mega-samples at 8 bits. The Analog Devices ADALM-PLUTO, or PlutoSDR handles 61.44 mega-samples at 12 bits. Now, to be clear, there are other limitations and considerations which I'm skipping over. Consider for example the speed at which each of these devices can talk to a computer, in this case over USB. I'm also going to ignore things like mixers, allowing devices like the RTL-SDR and PlutoSDR to tune across frequency ranges that go beyond their sample rate. Each of these three devices can convert an analogue antenna signal into bits that can be processed by GNU Radio. All of them can also be used to do the opposite and transmit. Yes, you heard me, several amateurs figured out that an RTL-SDR can actually transmit. Credit to Ismo OH2FTG, Tatu OH2EAT, and Oscar IK1XPV. The point being that whatever Bald Yak looks like, it will need to handle a range of A/D and D/A converters. As I've said previously, I'm aiming for this to work incrementally for everyone. This means that if you have a sound card in your computer or an $8 USB one, this should work and if you have an $33,000 NI Ettus USRP X410 lying around, this too should work. Also, if you have an X410 lying around not doing anything, I'd be happy to put it to use, you know, for testing. So, kidding aside, what about the rest of the Bald Yak experience? GNU Radio works with things called blocks. Essentially little programs that take data, do something to it, then output it in some way. It follows the Unix philosophy, make each program do one thing well, expect the output of every program to become the input to another, design and build software to be tried early and use tools rather than unskilled labour. Amateur radio transceivers traditionally use electronics blocks, but if we move to software, we can update and expand our capabilities as the computer we're using gets faster and the GNU Radio blocks evolve, and because it's all digital the computer doesn't actually have to be in the same box, let alone the same room, it could be in multiple boxes scattered around the Internet. So, the idea of Bald Yak is a collection of blocks that allow you to do radio things. You might have a separate box for each amateur radio mode, AM, FM, SSB, RTTY, CW, WSPR, FT8, FT4, Q65, but also modes like Olivia, FreeDV, SSTV, Packet, PSK31 or Thor. Instead of having to figure out how to wire these modes into your radio and your computer, the infrastructure is already there and you just download another block for a mode you want to play with. We'll need to deal with variables like which A/D and D/A converter is being used and what their limitations are. We'll also need to build a command and control layer and probably a few other things. I'm considering a few other aspects. For example, GNU Radio is mostly run with text files. We might distribute those using something like a web store. GNU Radio is proving hard to install, perhaps a LiveCD is the way to go. We'll need to come up with a base level of functionality and the documentation to go with it. I'm still contemplating how to best licence this all, specifically to stop it from being exploited. Feel free to get in touch if you have ideas. I'm Onno VK6FLAB

GB2RS News Sunday the 16th of February 2025 The news headlines: The RSGB has announced its Scout, Cadet and Girlguiding Youth Champion Listen out for stations operating for World Thinking Day on the Air New resources and ideas have been added to the RSGB British Science Week web pages The RSGB is delighted to announce that Samuel McCutchion, M7UEL will be the RSGB's Scout, Cadet and Girlguiding Youth Champion. Sam brings a wealth of hands-on experience to the role having been part of the Scouts from a young age in Beavers and then working his way up to Network. He then progressed to become an Assistant Section Leader. This knowledge will help the RSGB Youth Team to engage and offer amateur radio support to not only the Scouts but also the Cadets and Girlguiding. If you'd like to congratulate Sam on his role, or if you have any ideas you think would be useful to share, email him via youthchampion.scouts@rsgb.org.uk  Lots of amateur radio stations are on the air this weekend and next weekend for World Thinking Day on the Air. Listen out for them and encourage the young Girlguiding members. You can find details of some of the active stations via rsgb.org/thinking-day  but, if your station isn't listed, please share details on the RSGB social media channels. The event aims to encourage Girlguiding members to make friendships with those in other units, using amateur radio as the means of communication.   Have you visited the RSGB's British Science Week web pages yet? Two new worksheets have recently been added to inspire you to get involved and showcase amateur radio to new audiences. The activities were designed by the RSGB Outreach Team to fit in with this year's British Science Week theme of ‘Change and adapt'. If you'd like to deliver these activities to schools or youth groups, the Society has sample lesson plans, risk assessments and a guide to contacting your local school available on its website. Remember that British Science Week isn't just for younger audiences, it is open to all. If you're looking for ideas to get your friends and family involved or a local community group, go to rsgb.org/bsw  and visit the British Science Week resources page. There is a wealth of ideas available, from looking at the history of radio communications to building a sustainable system using only solar panels. If you have an activity planned for British Science Week, let the RSGB know by emailing the RSGB British Science Week Coordinator, Ian Neal, M0KEO via bsw@rsgb.org.uk  Details of events taking place will be shared on the Society's website.  The deadline for the RSGB Construction Competition is Saturday the 1st of March, which means you have less than two weeks left to submit your entry. The judges will be considering entries in six categories: beginners, construction excellence, innovation, software, antennas and outreach. To find out how to submit your application go to rsgb.org/construction-competition  The results of the competition will be announced during the 2025 RSGB Annual General Meeting on the 12th of  April.  If you are passionate about amateur radio and have some spare time to support fellow radio amateurs, why not become an RSGB District Representative? There are currently 12 vacancies across the United Kingdom, including in Belfast, Cambridgeshire and Lancashire. To find out if there is a vacancy in your region go to rsgb.org/volunteers  and then get in touch with the Regional Representative of the district with the vacancy. Amateur radio operators are reminded to take care when operating on the WRC-15 secondary amateur allocation at 5MHz. The UK still has no access to the full WRC-15 allocation. Despite requests, this seems unlikely to change in the foreseeable future. Whilst the UK is fortunate to have more generous licence conditions, these mustn't be put at risk by irresponsible operating in violation of the licence conditions, particularly in the 5358 to 5362kHz gap where there is no UK allocation. The RSGB website has detailed advice for operators, both for SSB and digital modes, on its rsgb.org/5mhz web page. Please take care not to transmit outside of the UK segments even if you hear other amateurs transmitting. Remember that signals heard may be coming from amateurs in other countries with different allocations. The RSGB ARDF Committee is pleased to announce the return of the British ARDF Championships in 2025. The Championships will be held as a three-day festival in early April 2025. Entries open on the 1st of March and will remain open right up until the event itself. Further information and updates can be found at tinyurl.com/ARDF25 Please send details of all your news and events to radcom@rsgb.org.uk  The deadline for submissions is 10 am on Thursdays before the Sunday broadcast each week.

The CQ 160m DX Contest starts at 22:00 UTC on Friday the 21st and ends at 22:00 UTC on Sunday the 23rd of February. Using SSB on the 160m band, the exchange is signal report and CQ zone. USA stations also send their state and Canadian stations send their province. The REF Contest starts at 06:00 UTC on Saturday the 22nd and ends at 18:00 UTC on Sunday the 23rd of February. Using SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number.  Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of February 2025 Two large coronal holes on the Sun's surface have been spraying solar material towards Earth, pushing the Kp index to a high of 4.67. The solar wind speed has been consistently higher than 500 kilometres per second and, with a south-pointing interplanetary magnetic field, the plasma has flooded into Earth's magnetic field. There have been a few aurora warnings, but these have only been minor. As a result, the ionosphere has not been too badly affected and daytime maximum usable frequencies over a 3,000km path have generally remained above 28MHz, with the odd dip towards 24MHz. Coronal mass ejections have not made an appearance and there were only three M-class flares between the 9th and 13th of February. Meanwhile, the solar flux index fell to the 150s and 160s last week. Recent HF DX has included the V73WW DXpedition on the Marshall Islands, which has been worked from the UK, including on the 40, 30 and 20m bands using CW. The TX7N DXpedition to Marquesas Island in French Polynesia has just finished. It wasn't an easy path, but it was worked from the UK on all bands from 30 to 12m using FT8, CW and SSB. Next week, NOAA predicts that the solar flux index could rise a little, to be in the 180 to 190 range. Once Earth is free from the effects of the current coronal hole stream, we may expect the Kp index to retreat, perhaps to a maximum of 2. So, DX next week could be quite reasonable but, as always, keep an eye on solarham.com for daily updates. And now the VHF and up propagation news from G3YLA and G4BAO The lingering high pressure just to the east of the UK is holding weather fronts over western Britain for the time being with any tropo benefits confined to eastern areas and being marginal at best.  During the coming week, changes will be slow but gradually a more determined push on the Atlantic fronts may bring them over most areas, except the extreme southeast of the country. This will make rain scatter more accessible although the models suggest that the fronts are likely to become weaker. So, they will not be especially useful by the time they reach the southeast. Sporadic-E is in its quiet season now, as are the meteor scatter prospects, with no major showers in attendance until the spring Lyrids in late April. Perhaps this quieter time is a chance to do some operating housekeeping. For example, you could update a list of nearby repeaters and beacons to help you track developing openings. Or maybe you could consider trying a new mode or band. Perhaps you could learn to use digital modes for meteor scatter. Maybe consider joining the increasing numbers trying CW on the 2m band. Moon declination went negative again on Saturday the 15th and path losses are rising as the Moon moves away to apogee, its furthest point from Earth, on Tuesday the 18th. 144MHz sky noise is low for most of the coming week but goes high for the weekend of Saturday the 22nd. And that's all from the propagation team this week.

GB2RS News Sunday the 9th of February 2025 The news headlines: A new RSGB web page focuses on emerging technology An upcoming talk at Bletchley Park Museum aims to widen awareness of the radio spectrum and radio transmission Remember to share your British Science Week ideas The RSGB has launched a new web page on how emerging technology can be used in amateur radio. Technologies such as artificial intelligence and 3D printing offer the opportunity to broaden the definition of amateur radio. They can also increase appeal and attract a more diverse audience. For existing radio amateurs, they offer the opportunity for progression through learning new skills. You'll also find links to two RSGB Convention presentations, including the newly released talk on 3D printing by Tom Wardill, 2E0JJI. Go to rsgb.org/emerging-technology  to learn more. The Society will be adding more technologies to the web page in the coming months and would love to hear from you if you are involved in amateur radio in any of these areas. Share your stories via comms@rsgb.org.uk  On Saturday the 29th of March, the RSGB National Radio Centre Coordinator, Martyn Baker, G0GMB, together with Andy Webster, G7UHN from the Radio Communications Foundation, will be delivering a talk in the Fellowship Auditorium at the Bletchley Park Museum. The presentation will introduce people to the radio spectrum and how to get to grips with the fundamentals of radio transmission. The session is being delivered as part of the RSGB's ongoing strategy to promote amateur radio to wider audiences. The Society is pleased to announce that RSGB members who would like to attend the talk can benefit from a 10% discount, reducing the price to £14.40.

The solar wind from a large coronal hole impacted the Earth on Saturday the 1st of February, pushing the Kp index to four. The hole was so large that the geomagnetic disturbance lasted until the early evening on Sunday. Once the solar wind speed had dropped, things got back to normal and the Kp index has been in the range of 1 to 2 ever since. The event appeared to have had little effect on HF propagation, with maximum usable frequencies over a 3000km path remaining above 28MHz during the daylight hours. So it looks like we dodged a bullet. At the time of writing, we have had 21 M-class flares in three days. A solar flare measuring M8.8 was detected around active region 3981, peaking at 0358UTC on the 3rd of February. This was the strongest flare yet from this region in terms of peak X-Ray flux. However, the flare itself was impulsive and was not the source of a coronal mass ejection. Over the next week, NOAA predicts that the solar flux index could fall slightly to be in the 180 to 200 range. Make the most of the good propagation as we may be entering a period of unsettled geomagnetic conditions again from the 10th to the 17th of February. NOAA predicts that the Kp index could rise to a maximum of 5 on the 13th but is likely to be in the range of 3 to 5 over the seven days. Part of this may be down to another coronal hole which became Earth-facing on the 6th of February. There is also a good chance that we could get an X-class eruptive flare from active regions 3981 or 3978, which could result in a coronal mass ejection. We recommend you keep an eye on solarham.com for daily updates. And now the VHF and up propagation news from G3YLA and G4BAO High pressure during the second half of last week brought some useful tropo conditions. As this week, ending today the 9th comes to a close there are some wintry showers along North Sea coasts, which may produce some snow and rain scatter. However, this may be weakened by the nearby high pressure.  By the end of this week, ending today the 9th, there will be a change of weather pattern as the high, having now migrated to Scandinavia, leaves room for Atlantic weather systems to encroach from the west during the coming week. This could bring rain scatter possibilities to the western side of the country. These should be more useful than the eastern coast ones at the end of last week since the rain will probably be heavier and the fronts slow-moving. This time of year is something of a desert for Sporadic-E propagation although look out for lesser events as a result of jet streams. You can track these on the Propquest website. Keep a look out for auroras during the week beginning tomorrow, the 10th. The likelihood of M-class flares is around 85%, while the chance of X-class flares is approximately 20%. So keep an eye on the Kp index for any potential solar events that could cause auroras. Next week, there are no major meteor showers. The next significant meteor shower, the Lyrids, will become active in April. Keep checking the pre-dawn period for random meteors. Moon declination reached a maximum yesterday, Saturday the 8th. Path losses are still low but will increase throughout the coming week. This means that this weekend, ending today the 9th, should produce good activity for EME, especially on the GHz bands with long Moon windows and high peak Moon elevation. 144MHz sky noise is moderate this weekend, ending today the 9th, but falls to low for the rest of the coming week. And that's all from the propagation team this week.

The majority of the sunspots are in the western hemisphere with very few in the eastern side. This means that the solar flux index could drop over the coming week unless there are sunspots ready to rotate into view to replace those being lost. A look at the STEREO Ahead spacecraft imagery suggests that there are indeed sunspots over the Eastern limb, so all may not be lost. Overall, the Sun has been fairly quiet. There were no X-class flares and only five M-class flares from the 19th to the 23rd of January. The Kp index has also been relatively low, only peaking at four for one three-hour period on the 20th of January. As a result, with the solar flux index in the 200s, HF conditions have been quite good. The maximum usable frequency over a 3,000km path has been consistently over 28MHz, from around 0830 to 1600 UTC. However, the 20, 17, 15 and 12m bands, seem to be carrying most of the DX at the moment. Next week, NOAA predicts that the solar flux index will remain in the mid-200s. Geomagnetic conditions are also predicted to be good until the end of the month, but a Kp index of 5 is forecast for the 31st of January, and this could last for a few days. So, we urge you to make the most of the conditions now, before geomagnetic storming, if it occurs, makes a mess of HF as we enter February.  And now the VHF and up propagation news from G3YLA and G4BAO The weather pattern is being driven by a very strong winter jet stream across the Atlantic Ocean. This gives scope for rapid development of deep lows and consequent gales and damaging winds. On Friday the 24th of January, the first big storm hit the northwest of Britain. We may find that the next low in the series is heading for southern Britain tomorrow, the 27th.  This all makes tropo unlikely for much of the week ahead since it stays unsettled through most of the period but with the smallest hint of higher pressure trying to return from Thursday. Rain scatter will probably be worth some consideration on the GHz bands while meteor scatter remains driven by random activity rather than any major showers. There have been further aurora alerts over the last week and it's always worth keeping the Kp index in view to monitor any possible chances for aurora. High figures, above a Kp index of 4, are a good trigger point to get interested. Moon declination reaches a minimum in the northern hemisphere today, the 26th, when Moon windows are at their shortest and peak Moon elevation is at its lowest. Path losses are now falling as we passed apogee on Tuesday the 21st. 144MHz sky noise is high, reaching over 3,000 Kelvin today, the 26th, before dropping to moderate until Wednesday when the Moon and Sun are very close in the sky for the whole Moon pass. After this, it drops to a low for the rest of the week. And that's all from the propagation team this week.

GB2RS News Sunday the 19th of January 2025 The news headlines: The RSGB is an official partner for this year's British Science Week Nominations are open for two RSGB Elected Board Director roles Don't forget to update your club's RSGB Club Finder information The RSGB is delighted to announce that it is an official partner for this year's British Science Week, run by the British Science Association.

It looks like the lull in sunspot activity is coming to an end as the solar flux index rose to 174 on Thursday the 16th, after a week in the 150s and 160s. The Sun was fairly bare, but there are now signs of more sunspot activity rotating into view. There have been no X-class flares in the past seven days and only one M-class event. This has meant that the Kp index has been low, thanks to a lack of associated coronal mass ejections. There were four during one three-hour period on the 13th of January. As a result, HF conditions have not been too bad with daytime maximum useable frequencies, or MUFs for short, over 3,000km regularly exceeding 24 and even 28MHz at times. However, nighttime MUFs are still in the doldrums, often struggling to get above 5MHz over a 3,000km path. This will no doubt change as we head towards spring. DX on the bands recently has included S01WS in Western Sahara and UP7WWA in Kazakhstan, both on 28MHz CW. Closer to home we have had GB200LB celebrating the bicentenary of the invention of the Braille code and GB1GKA commemorating the 100th anniversary of the Portishead Radio receiving station, callsign GKA, at Highbridge, Somerset. Both of these stations were active on the 20, 17, 15 and 10m bands using CW. At the other end of the bands, Kev, VK6LW, has been heard on 1822kHz from Western Australia at his sunrise at 2112UTC, as has Robert, DU7ET, in the Philippines at 2200UTC. January is a great month for top-band contacts. Next week, NOAA predicts that the solar flux index will remain in the 160 to 175 range. Geomagnetic conditions are predicted to be good with a maximum Kp index of 3. Watch solarham.com for news of solar flares and coronal mass ejections, which could easily send the Kp index higher and the MUFs lower. And now the VHF and up propagation news from G3YLA and G4BAO. The current spell of high pressure has served us well with some good tropo paths around the edge of the high into Spain and Portugal and even beyond to Madeira. This has shown how effective long maritime ducts can be around the edge of areas of high pressure.  On the 16th of January, the Atlantic was taking over the agenda and low pressure near Scotland was pushing a weakening front into north-western Britain as the high retreated east into Europe. The rest of the coming week has other lows bringing some rain or showers – especially to the north-west of the UK where it will become quite windy again. On Wednesday the 15th, weather models suggested a small high may return to the southern part of the country. We are in a rather unsettled weather period with some limited rain scatter potential for the GHz bands. Meteor scatter is also a bit thin with just a possibility of scatter via the Gamma Ursae Minorids, which peaked yesterday, the 18th. However, the number of meteors is at a very low rate and so is not a great option. Next, we move on to aurora and there continue to be examples of alerts suggesting minor events. Generally, though, spring is usually a better time, so there's still a while to wait. Saturday the 11th of January brought a welcome out-of-season Sporadic-E opening to Poland, and then the Balkans, on 50MHz lasting around three and a half hours from 1200UTC. Another good piece of news is the return of ionosonde data for the propquest.co.uk website after a few missing days. This is a timely opportunity to thank all those who maintain the professional data sets that allow us amateurs to see what the bands are doing. Moon declination is positive, going negative this Sunday. Moon windows will shorten, and peak Moon elevations fall. Path losses continue to increase as we approach apogee on Tuesday. 144MHz sky noise is low all week. And that's all from the propagation team.

GB2RS News Sunday the 12th of January The news headlines: There are opportunities in the RSGB's Regional Team World Thinking Day on the Air is coming up in February Are you interested in an exciting opportunity to volunteer with the amateur radio maker community? If you're looking to get involved in a different side of amateur radio this year, have you thought about becoming a volunteer RSGB Regional Representative for your area? There are eight Regional Representative posts available for nomination in this year's RSGB elections. This rewarding role will give you the opportunity to represent the views of members in your region to the Board, as well as supporting and advising the District Representatives located within the Region. Regional Representatives are also members of the volunteer Leadership Team and have the opportunity to contribute to the Society's strategy and policy development, as well as to its implementation. If you think this sounds exciting, and you are a confident communicator who has experience in managing people, then go to rsgb.org/election and read the candidate pack now. You'll also find details about how to apply, alongside information on other roles, including the RSGB President and two Elected Board Director vacancies. The closing date for all vacancies is 2359UTC on the 31st of January. So, act now and use your expertise to make an impact on amateur radio in your region. On the 15th of February, Girlguiding members will celebrate World Thinking Day on the Air. The aim of this event is to encourage Girlguiding members to make friendships with those in other units, using amateur radio as the means of communication. On this day, Crawley Amateur Radio Club and RSGB volunteers will be hosting a special event call sign GB1SCG, which relates to Sussex Central Guides. Girlguiding members of all ages will have the opportunity to celebrate by communicating via the amateur bands. If you or your amateur radio club are planning to work with a local Girlguiding group for World Thinking Day on the Air, please get in touch via comms@rsgb.org.uk  so the RSGB can promote your event.  As part of the RSGB's ongoing strategy to take amateur radio to new and diverse audiences, it is delighted to advertise a new volunteer role. This is an opportunity for someone to be an advocate for amateur radio within the maker community. The spirit of experimentation, curiosity and learning is common to both groups and the RSGB would like to foster greater crossover between the amateur radio and modern maker communities. This crossover would be centred around hackspace and maker spaces, as well as larger events, but would also encourage individuals from each community to inspire and learn from each other. This role is intended to help take amateur radio to a new audience with an emphasis on how the licence would support other hobbies, rather than the promotion of traditional amateur radio activities. To carry out this role you'll need to be open to working with different communities, be proactive and organised, and be able to build a team and help it to work to achieve goals. To find full details of the role go to rsgb.org/volunteers and if you're interested in applying or being part of a wider team, contact RSGB Board Director Mark Jones, G0MGX via g0mgx@rsgb.org.uk  The RSGB is recruiting volunteers for two roles that are fundamental to the delivery of the Society's Convention. The Convention Chair will be someone who understands the advantages of both online and in-person events. The successful applicant will have an awareness of all aspects of amateur radio and will contribute to shaping the RSGB Conventions of the future to suit the changing amateur radio audience. A second opportunity to be part of the Convention team is as the Society's Lecture Coordinator. This role is part of both the Convention and Tonight@8 teams and requires someone who is proactive and collaborative. The applicant will need to bring ideas for presentations that educate and inspire radio amateurs to try something new, learn more about interesting topics and expand their knowledge of amateur radio. To find out more about either of these roles and how to apply, go to rsgb.org/volunteers  Don't forget that the next event in the popular 145 Alive series will take place on Sunday the 26th of January 2025. It will run from 12 pm to 3 pm and there will be nets operating in most Maidenhead Squares across England, Scotland, Wales and Ireland. To take part in the event, which is designed to promote FM activity on the 2m band, all you need to do is call in and make contact with others. For more information visit the 145 Alive Facebook page.

First, let's take a look at last week's solar activity. As predicted, the solar flux index declined to the 160s. We had one X-class solar flare on the 4th and there have been 11 M-class flares since then. The net result was that the ionosphere was unsettled from the 4th to the 6th of January with the Kp index hitting 5 on the 4th. Following this, the Kp index was at 4 on the 5th and 6th of January. There were reports of visible aurora over the UK on Saturday the 4th, but it was nothing like the record-breaking aurora in April 2024. There were coronal mass ejections, or CMEs, over this period but they were mainly facing away from Earth. Maximum usable frequencies, or MUFs for short, held up over this period, although the shorter days meant that the MUF over a 3,000km path didn't stay above 28MHz for long after sunset. MUFs plummeted to below 10MHz by 1800UTC on Sunday the 5th. The message is clear – get your high-band DXing done by sunset! Next week it looks like the Sun is going into hibernation. The main sunspots will be disappearing over the western limb, leaving it looking a little bare. As a result, NOAA predicts that the solar flux index will remain low until the 16th when it is predicted to climb into the 200s once again. Unsettled geomagnetic conditions are forecast from the 16th to the 20th of January with a predicted maximum Kp index of 4. There are currently no coronal holes to worry about. So, in conclusion, this weekend ending the 12th looks set to be reasonable for HF operating, barring any X-class solar flares and accompanying CMEs. We predict that MUFs over 3,000km will be above 28MHz from around 0900UTC to 1500 UTC.   And now the VHF and up propagation news from G3YLA and G4BAO. We are in the middle of a proper winter cold spell at the moment, and we are about to see a large high coming over the country. This high is building in cold air and it means sharp frosts and perhaps some fog, so there's a chance of patchy tropo at times. Conditions may further improve as the high slips south after this weekend ending today the 12th. This may allow milder, moister Atlantic air in from the west to improve the refractive index contrast across the inversion, which could lead to tropo. The solar conditions have remained interesting and produced a few aurora alerts, so we can probably benefit from watching the Kp index during the coming week.  Meteor activity has passed its early January peaks, and we are now sliding back into random meteor activity as our best option. These tend to be better just before dawn. There is just one minor shower this week. The Gamma Ursae-Minorids are active from the 10th to the 22nd of January and peak on the 18th. We have mentioned Sporadic-E quite a lot recently but, with the passing of the meteor activity, the chances of it occurring have reduced considerably. Although limited activity may enhance the lower bands, it probably won't feature in the usual high HF and VHF bands. The Moon reaches maximum declination this weekend, ending today the 12th. Moon windows are long and peak Moon elevations are high. Path losses are also high and increasing all week. 144MHz sky noise is low all week. And that's all from the propagation team.

Could you spare some time and share your expertise to make a difference within the amateur radio community? The RSGB 2025 elections process has begun, and nominations are open for a range of volunteer roles. The RSGB's President John McCullagh, GI4BWM will reach the end of his second year as President at the AGM and so will stand down. There are also two Elected Board Director vacancies. The Board is looking for people with specific skills to fill these roles. The current President is one of the few at the Board level with extensive experience in spectrum matters and negotiating with the authorities – so that skills gap needs to be filled. Outreach has been an important focus over the last year for the Society and it would like to support the current activities and expand on them. These developments will include encouraging practical skills amongst the amateur radio community and also building links with other organisations. Building those relationships will require someone with drive and determination but also tact and diplomacy. There are eight further posts available for RSGB Regional Representatives, ranging from Region 1 in Scotland to Region 11 in the southwest. For more details about the roles as well as application forms and candidate packs, go to the RSGB website at rsgb.org/election  December 2024 saw a wide range of individuals, clubs, schools and universities encouraging youngsters to get on the air and try amateur radio as part of YOTA Month 2024.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 2nd of January 2025. We started the new year with a bang, or more precisely a Kp index of 8 and widespread visible aurora. This was caused by a partial halo coronal mass ejection, associated with an eruption in the Sun's southeast quadrant on the 29th of December. The strong G3 to severe G4 geomagnetic storm peaked at about 1800UTC on the 1st of January as the solar wind speed moved past Earth at just above 500 kilometres per second. It then subsided as the Bz component settled into a north-pointing position. HF propagation suffered as a result with the maximum usable frequency down for the rest of the evening. By the morning of the 2nd of January, things had improved and maximum usable frequencies over a 3,000km path were back above 28MHz. The solar flux index remained above 200, which no doubt helped, but we are in rocky times from a space weather point of view. A large coronal hole became Earth-facing on Friday the 3rd of January which will no doubt cause some geomagnetic disruption today, the 5th, as the Kp index rises. NOAA predicts the solar flux index may decline this week, possibly ending in the 160s to 170s. Geomagnetic conditions may also be in for a rough ride around the 10th and 11th when the Kp index is forecast to reach 4. From a radio point of view, January is a peak time for low-band DXing. The nights are long and dark so make the most of the 160 and 80m bands. You may also get DX during the late afternoon on the 40m band. During the daytime keep an eye on the 10m band, which may throw up the odd, interesting DX station while the solar flux index remains high.  And now the VHF and up propagation news from G3YLA and G4BAO. To start the year the main feature is low pressure over the country but, in the depths of winter, it's good to remember that snow and rain both provide scattering opportunities for the GHz bands. There is a glimmer of tropo hope for the end of the coming week, around the 11th and 12th, as high pressure builds over northern Britain. This will be a cold-air high which tends not to be the best for tropo, but it's worth a look nonetheless. The solar conditions provided an aurora on New Year's Day with a brief index of 8 during the afternoon. With other disturbances possible, it is worth keeping up to date with solar conditions and prospects for geomagnetic storms on spaceweather.com  This is one propagation mode where CW is so much easier to copy under the difficult conditions of aurora. Meteor scatter propagation is driven by the Quadrantids in the first week of January. It peaks on the 4th but spans the period up to the 12th. This is a productive shower with an hourly rate of 120. Since it's the last major excitement until the late April Lyrids, make the most of it before we're reduced to chasing random meteor activity during the rest of winter. We have previously mentioned the chance of out-of-season Sporadic-E propagation in mid-winter and we still have the next week to keep alert, especially in view of the Quadrantids adding fuel into the E region. The ionised trails of the meteors provide long-lived metallic ions, which is the material that gets focussed into Sporadic-E if we are lucky. The Moon starts the weekend with a negative but rising declination, going positive today, the 5th, so Moon windows continue to lengthen. Path losses are low with perigee on Wednesday. 144MHz sky noise is low all week. And that's all from the propagation team this week.

Foundations of Amateur Radio In the analogue world you throw up an antenna, turn on your radio, tune to a station and sound comes out. Aside from propagation restrictions, you don't particularly care when you do this. In contrast, if you fire up a WSPR or Weak Signal Propagation Reporter, each transmission lasts 110.6 seconds, every 120 seconds, starting on the even minute. An FT8 signal takes 12.6 seconds within a 15 second window. In other words, to use WSPR or FT8 you need to both transmit and receive at the right time for this to work. You don't need to go to modern modes to get the idea that time matters. Listening to any CW signal will give you an idea that time and timing is important. To give you a sense of what I mean, if you turn on your radio in the middle of a dah, in the middle of a letter, you're likely to hear the wrong symbol, perhaps decoding the partial dah as a dit and missing the first part, hearing a partial letter Q, dah dah dit dah as a dit dit dah, the letter U, and that is completely ignoring inter letter and inter word spacing. The point being that time matters for radio signals. So, if we're going to build a system that can handle radio signals inside a computer, we'll need to deal with time. Decoding is one thing, but what if you want to compare two radio signals from two different antennas? You can build a direction finding tool consisting of multiple antennas that can determine the direction of a signal by calculating the difference in time between when a signal arrived at one antenna and when it arrived at another. Of course, the distance between each antenna matters, so we'd need to deal with time in such a way that we can actually measure this. RF travels about 30 centimetres in a nanosecond. If that's not enough, what happens if you're digitising an analogue signal and sending it across the network to be processed? Not only do you need to track if information arrived at its destination or was lost in transit, if you're combining multiple signals, you'll also need to know when the information was captured. Which brings us to something entirely different and perhaps surprising. If I say "now", that moment is not the same for everybody on the planet. You might be listening to this on the train to work, your local repeater, on YouTube, or reading it on social media or in your email. Even me writing the word and reading it out loud are two different times. In other words, agreeing on time is not obvious. We could all look at the clock and share the information, but is that accurate enough? Do we tell each other how many seconds past midnight UTC, or do we need to know half or tenths of seconds? To use WSPR and FT8 it's generally enough to use the NTP or Network Time Protocol. It can be as accurate as 1 millisecond, but is that enough? To give you a sense of how precise we might need to be, a HF signal takes about 66 milliseconds to travel halfway around the globe. A mobile phone tower signal travels 6 kilometres in about 0.02 milliseconds, so NTP isn't really precise enough for what we might need. If you've played with a GPS, you might know that you can use it to determine when "now" is. It's theoretically capable of a 14 nanosecond accuracy, but by the time you actually use it, it's more like 100 nanoseconds. There's a million nanoseconds in a millisecond and a billion nanoseconds in a second. If you were to store nanoseconds as a 64-bit unsigned number, you could count between now and just over 584 years from now. Something else to consider. If you had two analogue to digital converters and you wanted to synchronise them, 1 nanosecond would allow you to get two 1 GHz signals to start at the same time, providing that you knew what time it was to that level of accuracy. If you're keen, look up maser. Before you point out that this means we'd be limited to anything below the 23cm band at 1.2 GHz, I'd like to mention that this is about representing all of it, 0 Hz to 1 GHz as one chunk of spectrum at the same time. In reality, you're much more likely to only want part of that, not to mention that we'd need to transport and process all that data as well. Which brings us to bandwidth considerations, but that's a conversation for another time. Credit to Nick VA3NNW, Kent AC1HJ, Dave VK6KV and Randall VK6WR for their thoughts and explanations.

GB2RS News Sunday the 22nd of December The news headlines: The RSGB is looking for a new Lecture Coordinator YOTA Month draws to a close but is still busy on the air The first RSGB Tonight@8 webinar of 2025 focuses on GB2RS The RSGB facilitates just over 60 lectures each year in a mixture of in-person, hybrid and remote formats. 50 of these are at the RSGB Convention and 11 are delivered through the livestreamed Tonight@8 webinar programme of events. This set of presentations aims to cover a wide mix of amateur radio-related subjects, across all depths of amateur radio experience and knowledge. They are watched and admired by RSGB members and non-members across the world. The RSGB Lecture Coordinator is part of the Tonight@8 and Convention teams. Its recent Lecture Coordinator Keith Hotchkiss, G0FEA has stepped back to focus on his professional commitments, so the RSGB is looking for someone new for this volunteer role. The right person will be proactive and collaborative, bringing ideas for presentations that educate and inspire radio amateurs to try something new, learn more about interesting topics and expand their knowledge of amateur radio. They will lead the invitation and scheduling process for Tonight@8 webinars and contribute to the decisions about Convention presentations. They will also be the main contact with Convention presenters, inviting them to speak, updating the speaker project plan and helping to create a balanced programme. Reporting to the Convention Chair, the Lecture Coordinator would be a member of the RSGB Convention team but would not be required to take responsibility for organising and managing other aspects of the event. If you're interested in the role or would like to find out more, please contact the RSGB General Manager Steve Thomas, M1ACB via gm.dept@rsgb.org.uk Youngsters on the Air Month is nearly at a close. It has been filled with some brilliant activity from young people using special callsign GB24YOTA. Thank you to everyone involved, from supervising young amateurs to making contact with them on the air. Before the year ends, we still have some activity using GB24YOTA, so please continue to listen out. Tomorrow, Monday the 23rd of December, Hilderstone Radio Society will be back on the air as it hosts the callsign for a final time this month. On Sunday the 29th of December, Bushvalley Amateur Radio Club in Northern Ireland will be operating GB24YOTA, followed by Marlborough Scouts on Monday the 30th of December.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 19th of December 2024. The last week was a little more disturbed than usual and we had a Kp index that hit 5.33. An enhanced solar wind stream contributed to active geomagnetic conditions and an interplanetary shockwave, that swept past Earth at 0519UTC on the 17th of December, caused minor G1 geomagnetic storming. A far-sided halo coronal mass ejection event also occurred later on the 17th of December at 1600UTC although this was not directed towards Earth. This shows that the Sun is still very active, and we should not be surprised if we experience more solar flares and CMEs. The solar flux index stayed in the 160s and 170s and we should keep an eye on active region 3927, which is currently turning to be Earth-facing and has already been the source of some C-class solar flares. Next week NOAA predicts that the solar flux index may rise slightly to be in the 180s. The largest Kp index forecast is 2, which probably means that NOAA is unsure about what will actually happen. We are pleased to report that OF9X is once again on the air from the land of Santa Claus in Lapland. Up to 16 operators will operate Santa Radio on the 160 to 6m bands using CW, SSB, RTTY, FT4 and FT8. They have already been spotted on the 30 and 20m bands using CW and on the 12 and 17m bands using RTTY. So, there is plenty of scope to work them. According to the prediction program Proppy, paths to Lapland should be open on 14MHz from 0800UTC to 1800UTC. On 28MHz, expect them to be open from 0930 to 1500UTC. The 80 and 40m bands should be mainly open during the hours of darkness. As always, across the Christmas period, we recommend that you use solarham.com and propquest.co.uk for real-time updates on solar and ionospheric conditions. And now the VHF and up propagation news from G3YLA and G4BAO. Last week ended in a colder unsettled period of weather with strong north-westerly winds and spells of rain or showers. The air is sufficiently cold that some snow is possible over northern hills. This is potentially good news for rain or snow scatter, especially off fast-moving showers down the coastal fringes of the UK.  Although the nearest high remains near the Azores to begin with, it slowly migrates east to France and, by Christmas, to central Europe. This will bring high pressure and possibly Tropo onto Santa's list from Christmas Eve onwards. Look for patches of misty low cloud or fog for the best conditions. As usual, check for other modes. Meteor scatter and aurora are both worth consideration and this is a prime time for out-of-season Sporadic-E between now and about mid-January.  One of the helpful aspects of looking for winter Sporadic-E is that quite often the jet streams are significantly stronger than in the more traditional summer Sporadic-E season. Jet streams are a good source of turbulence that can eventually propagate up to the E region to make Sporadic-E propagation. Jet streams are shown on upper air charts and can be a good geographical guide to Sporadic-E prospects in the summer and should therefore be similarly consulted for these winter events. In this case, they tell us that the first half of the coming week, up to Christmas Day, is well set up with a northerly jet stream over central Europe and, more importantly, crossing the Alps. So, a second mode goes on to Santa's list. Check the VHF Cluster's Sporadic-E graphs at propquest.co.uk for early signs of activity, particularly for paths to the southeast into Italy and the Balkans. The Moon started this weekend with positive declination but goes negative late today, the 22nd. Path losses are at their highest due to apogee on Christmas Eve. 144MHz sky noise is high until Wednesday, including near-eclipse conditions all day on Monday. That's it for this year. How about making a New Year's resolution to try a new mode? Maybe use SSB or CW on VHF now and again and put out lots of CQ calls in 2025! And that's all from the propagation team this week.

GB2RS News Sunday the 15th of December The news headlines: The RSGB 2025 election nominations process is open The Society is advertising for a new Convention Chair YOTA Month is busy this week with more callsign hosts to listen out for The RSGB 2025 elections process has begun, and nominations are open for a range of volunteer roles. The RSGB's President John McCullagh, GI4BWM will reach the end of his second year as President at the AGM and so will stand down. There are also two Elected Board Director vacancies. The Board is looking for people with specific skills to fill these roles. The current President is one of the few at the Board level with extensive experience in spectrum matters and negotiating with the authorities, so that skills gap needs to be filled. Outreach has been an important focus over the last year for the Society, and it would like to support the current activities and expand on them. These developments will include encouraging practical skills amongst the amateur radio community and building links with other organisations. Building those relationships will require someone with drive and determination but also tact and diplomacy. There are eight posts available for RSGB Regional Representatives, ranging from Region 1 in Scotland to Region 11 in the southwest. For more details about the roles as well as application forms and candidate packs, go to the RSGB website at rsgb.org/election The RSGB has been developing its Convention over recent years to suit the changing needs of the amateur radio community. From a face-to-face meeting, it evolved into an online event when we weren't allowed to meet, then changed again into a hybrid event, bringing together the best of both for people in this country and across the world. The Society has also been developing the programme to include practical workshops and forums to support radio amateurs who would like a safe and accessible environment in which to try to develop their practical skills. The RSGB General Manager has been doing the role of Convention Chair for the last three years but has now stepped back from that additional voluntary role, so the RSGB is looking for a new Convention Chair. This role needs someone who understands the advantages of both online and in-person events and who can contribute to shaping the RSGB Conventions of the future to suit the changing amateur radio audience. The RSGB is looking for someone enthusiastic, proactive, collaborative and good at working with others in a strong team. They will also need an awareness of all aspects of amateur radio, including the latest developments and what might be on the horizon. As part of the wider Convention team, they will need to suggest ideas for speakers and practical activities that will attract a range of radio amateurs. If you believe you could contribute to the development of this prestigious annual event, the RSGB would like to hear from you. Please contact the RSGB General Manager Steve Thomas, M1ACB via gm.dept@rsgb.org.uk Youngsters on the Air Month is now halfway through, with plenty more operators booked to host GB24YOTA. There is still time to work the RSGB National Radio Centre's GB3RS station which is hosting the callsign for the duration of today, Sunday the 15th of December. On Wednesday, the 18th of December, the Simon Langton Boys School in Canterbury will be operating between 12 pm and 6 pm. On Thursday, the 19th of December, between 12 pm and 6 pm the Cambridge University Wireless Society will once again be hosting GB24YOTA. To finish up this week, Tommy, M7OMY will be operating on the 20th and 21st of December under the supervision of Las, M0BOY. Tommy is a young radio amateur and has been taking part in YOTA Month for a few years, so be sure to listen out and make a QSO with him. Search GB24YOTA on QRZ.com  to view the full operating schedule. The RSGB's headquarters will close for the Christmas and New Year period from 2pm on Tuesday the 24th of December 2024.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 12th of December 2024. We had another week with quiet geomagnetic conditions. Other than three hours with a Kp of four on the 9th of December, as of last Thursday when this report was being compiled it had been below three for the past seven days. Active region 3920 produced an impulsive M2.8 solar flare, peaking at 1006UTC on the 11th of December. A quick M2.0 flare was also detected around AR3922 in the southeast quadrant. There was also an M6.4 solar flare at 0648UTC on the 10th of December, but no Earth-directed coronal mass ejections were observed. The solar flux index, despite being predicted to reach 200 again, has been simmering away in the 160s and 170s. Nevertheless, the quieter geomagnetic conditions have helped HF with the extrapolated MUF over a 3,000km path often hitting 40MHz at times. However, the early sunset, which is around 1538UTC to 1621UTC at the moment depending on your location in the UK, means that the MUF drops off quite quickly in the afternoon. The average critical frequency at night is currently about 3.0-3.5MHz, which explains why the HF bands appear to be dead. The winter solstice is on the 21st of December, and we won't see much change until we get to mid-January. There is DX to be had with CDXC members reporting working YJ0CA (Vanuatu) on 15 metres, V73WE (Marshall Islands) on 30 metres and YI1QEA (Iraq) on 10 metres. So, at the moment, make the most of the daytime DX and greyline openings, and reserve the evening for Top Band and perhaps 80 metres. Next week, NOAA predicts that the solar flux index will remain around 170 to 175. The Kp index is expected to be around two or three, apart from the 19th of December when it could reach four. And now the VHF and up propagation news from G3YLA and G4BAO. The period of enhanced Tropo activity will have faded away by this weekend as the high pressure slips away into Europe and declines. This allowed low pressure to regain control from last Friday through the current weekend. There may be a chance of some rain scatter propagation on the GHz bands, although it doesn't look like a particularly good example.  All is not lost for Tropo followers, since the next high drifts in from the Atlantic early next week. The southern UK will benefit the most with Tropo paths to France and across Biscay. This lasts until midweek, to be followed by a return of low pressure for the second half of the week and probably a better rain scatter option than this weekend. The big Geminids meteor shower peaked yesterday, the 14th of December, but will linger throughout the month. The radiant source rises late afternoon and sets the following lunchtime and is most favourably positioned late evening and early morning, pre-dawn. Next, a consideration of aurora prospects, which are still a little enhanced by solar conditions. So, as usual, stay alert to an increasing Kp index above Kp=4 to keep in the game. Finally, remember that the period of Christmas and early January is well known for producing random out-of-season Sporadic-E. It's not possible to fine-tune Es prospects this far ahead, but it wouldn't hurt to monitor the f0Es traces on the www.propquest.co.uk website between now and mid-January. The Moon's declination is at maximum today, Sunday the 15th of December, and also on Monday, so expect long Moon windows with high peak elevations. Path losses are still low but rising, so it's still a good week for EME. The 144MHz sky noise is moderate to low all week. And that's all from the propagation team this week.

Foundations of Amateur Radio Bald Yak, week 2 During the week an interesting question was put to me. Am I going to make this into a GNU Radio tutorial? In short, no and yes. At this point I know enough about what I'm attempting, to recognise that I'll be deep diving into the bowels of GNU Radio and the inevitable idiosyncrasies that a large project like that has and as a result I'll likely have to explain the context in which something broke, which will no doubt result in me having to walk you through the details. So, this means that there will be trips into how this thing works, but I'm not currently planning a GNU Radio course, not only because that's not what Bald Yak is about, but because I like to know what I'm talking about, even if the peanut gallery might at this point call out: "Why start now?" -- yes, from time to time, what I'm talking about here is based on something I'm still in the process of learning and obviously I make mistakes. Now, if you haven't been playing along, let me state the purpose of why I'm here. "The Bald Yak project aims to create a modular, bidirectional and distributed signal processing and control system that leverages GNU Radio." In the pursuit of happiness, I've been resisting making a table with the various communication protocols in use to extract data and control the data stream within the software defined radio world. I've been avoiding this because I don't feel like I know the landscape well enough. Of course, making the table will create a better understanding, chicken and egg. I do have a handle on what functionality is required. So, in the spirit of writing it down or it didn't happen, here's what I know. This thing needs to be bi-directional because it needs to be able to receive and transmit. I don't yet know if this functionality needs to be symmetric. What I mean by that is that I don't know if both directions need the same functionality. Consider for example a distributed receiver decoder. Imagine a device that spits out bytes at a particular rate. These bytes represent received radio signal. How and what they are specifically I'll leave alone for the moment. This information needs to be read and processed. The processing could happen on the same computer, or it could be a separate computer connected to the local network, or a remote network across the internet. There could be more than one computer doing the work. We could choose to send the whole stream of bytes, our radio signal, to every computer. This is how YouTube works when multiple people watch the same video - and yes, I'm ignoring caching for the moment. It requires a boatload of network bandwidth and hardware. You could send part of the signal to a receiver, this is how WebSDR works. This requires a mechanism to select and control each part of the data stream. A third option is to use a networking technique called multicast. It provides a way to send a data intensive stream, like our radio signal, to multiple computers simultaneously. NASA uses this to distribute radio signals all over the place. I used it in the early 1990's to broadcast a live radio show I hosted, Online Computing Radio, across the globe with listeners in Sweden, Switzerland and Greenland whilst I was in a radio studio in Perth, Western Australia. This only to say that multicast has been around for a long time. Another way to look at this is that a radio transmission is a multicast signal. As long as you're within range, anyone can receive the same signal. To keep track of what we were talking about, this is discussing how a digitised received radio signal is distributed to various computers for processing. Each of those three methods can be combined in interesting ways depending on requirements. For example, a spectrum logging tool might expect the entire stream, but an FM decoder might only want one little slice, a RTTY decoder might want a different slice and an FT8 decoder yet another. Before I go on, let me come up with some terms. No doubt these will get refined, but for now, I'm going to define a receiver as a computer that acts as a destination, or sink, for a stream of radio bytes across the network. Similarly, I'll define a computer that generates a source of radio bytes as a transmitter. I'm not yet sure what to call the computer that's physically connected to the antenna, but I'll start with using the term "antenna node". This isn't strictly accurate, since there's more than an antenna there, but I have to start somewhere. I note that GNU Radio calls a transmitter a source and calls a receiver a sink. With that nomenclature, our "antenna node" would be considered both a sink and a source, which doesn't really help us here. Back to the receiver. All of this needs some form of control intelligence, as-in, a receiver needs to be able to control where the signal comes from, or said differently, you need to be able select an antenna node. Not only that, you need to be able to tell the antenna node specifically what data you want and perhaps in what form. Now, on the reverse side of this, the transmit chain, do we need the same functionality? Does an antenna node need to be able to accommodate multiple transmitters? Does such a thing exist? Do we want it to exist? How would we get one data stream from the transmitter to the antenna node? How would we do this with multiple streams? Is the same control system required? At this point you're likely to realise that this isn't trivial. We can pick something and just start, but I'd like to spend at least a little amount of time considering the options. With over 40 years in the computing field I'm leaning towards making the transmit and receive identical because we don't yet know what we don't know and besides I can sort of see how multiple transmitters might use the same antenna node and what the real world applications of this might be. Something else to wrap your head around, what if the transmit logic was the reverse of the receive logic, as-in, the same thing, just swapping sink and source around. It has a certain elegance about it, even if I don't yet know how this might be achieved. I'd also like to take a moment to thank Kevin VE7ZD, Nick VA3NNW and Mark W1MM for their thoughts and suggestions. Keep them coming. I'm Onno VK6FLAB

Using all modes on the 2m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 28th of November 2024. Last weekend's CQWW CW contest was a reminder of just how good HF propagation can be near sunspot maximum. The whole world was workable on the contest bands up to 10 metres, including the Far East, Australasia, the Caribbean and South America. It was a great opportunity to increase your DXCC total and have fun at the same time. This week's solar flux index crept back above 200 again, peaking at 225 as this report was being prepared. Geomagnetic conditions have been surprisingly good over the past seven days with a peak Kp index of 3.67 on the 24th of November. There have been no X-class solar flares, but there has been a total of 13 M-class and 54 minor C-class flares over the past seven days. There have been coronal mass ejections, notably on the 25th of November, but they have not been Earth-directed as of the 28th. So, to summarise, HF conditions have been pretty good. We are now entering the Winter period for HF propagation, which tends to favour the low bands. So 160m, 80m and 40m come into their own and night-time DXing becomes the norm. Look for greyline openings to the west at sunrise on 80m and 160m, and also short, but good, openings on 40m in the late afternoon. Nighttime may bring good DX on 80m and 40m, including the Caribbean and South America. NOAA predicts that the SFI will remain in the low 200s next week, and while geomagnetic conditions are forecast to be good at first, the Kp index may rise to four on the 4th to 6th of December. This could result in reduced MUFs until the Kp index recovers. And now the VHF and up propagation news from G3YLA and G4BAO The unsettled theme continues through most of the next week or two. The only signs of slightly enhanced prospects for Tropo are as we close this week, and even that is restricted to some eastern areas for paths across the North Sea. A second option may temporarily appear around the middle of the coming week as a weak high crosses southern areas, but this one looks to be a cold high and probably not so good as a vehicle for Tropo. The meteor scatter prospects are aided by the last throes of the Leonids which fade away by this weekend, and the Orionids which peaked on Thursday the 28th of November, but last through the coming week. The unsettled weather should offer some useful GHz bands rain or snow scatter, since there will be several active weather systems around. This early in the winter is a great time for strong shower activity around the still relatively warmer seas. The auroral prospects are worth checking after recent activity. Look for watery-sounding signals on the LF bands as a good clue along with Kp index values greater than four. Last week saw some fleeting signs of Sporadic E on the Dourbes ionosonde graphs on propquest.co.uk, especially on Monday the 25th of November. This occurred typically around the middle of the day and was probably driven by the very strong jet stream and the current meteor activity. The Moon's declination is negative, reaching minus 28 degrees on Monday and we are close to eclipse on Sunday. That's followed by two days of high 144MHz sky noise, so with path losses still high, EME operators should probably take the opportunity to check their antennas after last week's gale. And that's all from the propagation team this week.

GB2RS News Sunday the 24th of November   The news headlines: The past and the future – the RSGB releases more Convention presentations RSGB Tonight@8 on HF antennas – join the last live event of 2024 Encourage youngsters on the air during YOTA Month   The RSGB continues to share some great presentations from its recent annual Convention. The two this week look back to the important history of amateur radio and contrast that with how amateur radio might be influenced by modern technology. Don Beattie, G3BJ discussed the very different amateur radio environment of 1924, and the history and events of October that year when the first two-way trans-global radio communication between the UK and New Zealand took place. This centenary celebration is just one of a range of activities that have included RadCom articles and a re-enactment of the contact at Mill Hill School. In his presentation on using AI to write simple amateur radio applications, RSGB Board Chair Dr Stewart Bryant, G3YSX considers how using AI software can improve productivity and bring the ability to write effective software within the reach of more people. This presentation is being released separately as part of the RSGB's focus on encouraging coding and programming activities amongst the amateur radio community. You can find a range of coding resources on the RSGB website at rsgb.org/coding  To watch both presentations, go to the RSGB YouTube channel and choose the ‘RSGB 2024 Convention' playlist. The final RSGB Tonight@8 webinar of 2024 is on Monday the 2nd of December. The presentation by Tim Hier, G5TM will focus on the various HF antennas available for portable operating. He will also look at how to use very basic modelling software to ascertain the choices you have at your disposal. Tim's ethos when working portable is simple, “Five minutes from arrival to operating and no more”. Tim is also the editor of RadCom Basics and will refer to content in that RSGB publication that will help radio amateurs who want to try portable operating. Watch the webinar live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat. To find out more go to the RSGB website at rsgb.org/webinars Youngsters on the Air Month begins one week today. Callsign GB24YOTA will be active for the month, hosted by a range of groups, clubs and individuals. Marlborough Scout Group will be the first team of youngsters to operate. They will be on the air before midday on Sunday the 1st of December, and then again after 6 pm on the same day. Also operating the special callsign next Sunday will be the Cambridge University Wireless Society. They will be hosting the callsign between 12 pm and 6 pm. Remember to listen out and have a QSO with a young radio amateur on the air. If you'd like to get involved, you've still got time. Go to QRZ.com  and search for GB24YOTA to check availability and then email Jamie, M0SDV at yota.month@rsgb.org.uk to register your interest.  The RSGB VHF Contest Committee is currently planning the rules for the 2025 VHF contests. Following some discussion at the RSGB Convention, the committee members have some questions on which they would appreciate feedback from contestants, with particular topics focused on VHF Field Day and the Back Packers events. You can find the survey online at tinyurl.com/VHFCC2025 and it will close on Friday the 6th of December. Members of Wokingham u3a Amateur Radio Group have secured a new club call sign, G5UTA. The group operated the callsign for the first time during the national u3a week in September. G5UTA can be used by any u3a member with a Full licence, in support of a u3a event or demonstration. You can read more about the new callsign, including how to apply for authorisation to use it, in the January 2025 edition of RadCom. To find out more about amateur radio as a subject area within u3a, you can contact its new subject adviser Paul, G0NDN via the u3a website at tinyurl.com/u3asubjects The historic VLF transmitter at Grimeton Radio Station in Sweden is celebrating one hundred years since it was put into commercial operation. The unique Alexanderson alternator operates using callsign SAQ. To mark the centenary a special transmission will take place at 1000UTC on Sunday the 1st of December using CW on 17.2kHz. The event will be livestreamed on the organisation's YouTube Channel using the handle @AlexanderSAQ.

Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14. On Tuesday, the 26th of November, the RSGB SHF UK Activity Contest runs from 1930 to 2230UTC. Using all modes on the 13cm, 9cm, 6cm and 3cm bands, the exchange is signal report, serial number and locator. On Wednesday, the 27th of November, the UK and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. On Thursday, the 28th of November, the RSGB 80m Autumn Series CW Contest runs from 2000 to 2130UTC. Using CW on the 80m band only, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of November. We've had yet another week of relatively calm geomagnetic conditions. The solar flux index has been in the 160s and despite having 14 M-class solar flares over seven days, we haven't had any coronal mass ejections to contend with. As a result, the daytime maximum usable frequency, or MUF, over a 3,000km path has been high, reaching more than 35MHz at times. The MUF declines after sunset, as expected, settling at about 12-13MHz, meaning the only HF band open to DX has been the 10MHz or 30-metre band. DX this week has included 3D2Y in Rotuma. This Pacific DXpedition has been spotted in Europe, on 20m, 15m and 17m CW, so plenty of choice as to which band you try. E51SGC in Rarotonga on the Cook Islands has also been spotted across many of the HF bands, but they will be leaving on the 24th of November. The good news is that the team of Stan LZ1GC and Ted LZ5QZ are moving on to Tonga as A35GC from the 25th of November until the 7th of December 2024. Gerben (PG5M) is active on the Falkland Islands as VP8G and has been spotted on 20m, 15m and 10m CW. He is there until the 25th of November so get in quickly! Next week, NOAA predicts that the SFI may rise to the mid-250s again. Geomagnetic conditions are largely predicted to be good, although do keep an eye on solarham.com for updates. And don't forget the CQ Worldwide CW contest this weekend which should bring a lot of DX to the HF bands. And now the VHF and up propagation news from G3YLA and G4BAO. The weather is now in an unsettled phase with areas of low pressure bringing alternating spells of mild wet and windy weather interspersed with colder brighter and breezy showery weather.  This raises a couple of radio-related points; one is that we will see some very strong and potentially damaging winds in some areas, so check daily forecasts and make sure your mast guys are secure; and secondly an absence of any marked high-pressure Tropo weather.  Rain and snow scatter may be worth checking on the GHz bands in such unsettled weather. Meanwhile, meteor scatter is worthy of greater attention as next week's list of showers includes the small Alpha Monocerotids shower and the tail end of the big Leonids shower.   This introduces another potential nugget of interest in that it is widely accepted that meteors form the source material for Sporadic-E. Despite being out of season in the traditional sense, the prevalence of stronger jet streams in unsettled weather makes the next week a possible ‘watch period' for Es. If you are curious about what these might look like, check out the propquest.co.uk  website and look for the near vertical incidence skywave or NVIS tab for Wednesday the 20th of November 2024. During the two events in the middle of the day and evening, the critical frequency of the Es layer reached values of nearly 10MHz, which could equate to four-metre propagation on a good day. You will see the Es blog tab upper air charts also show a jet stream of greater than 100 knots.  For EME operators, the Moon has passed peak declination so Moon availability and peak elevation will be falling. Path losses are high and rising towards apogee on Tuesday the 26th. 144MHz sky noise is low all week. And that's all from the propagation team this week.

GB2RS News Sunday the 17th of November The news headlines: The RSGB has launched a new practical events section on its website The RSGB Awards Manager has added categories to the IARU Region 1 Award There is still time to host the Youngsters on the Air Month call sign The RSGB is keen to promote practical events for radio amateurs as a way of developing their skills and retaining their interest in amateur radio. The Society has also demonstrated that buildathons are a great way of engaging new audiences, giving people a taste of amateur radio in a fun and supportive environment. As part of its strategy, the RSGB held two workshops at the 2024 Convention to introduce individuals to radio-related usage of Micro Controller Units, or MCUs as they are often known. The Society also holds annual build-a-radio events at Bletchley Park for youngsters, with the kits provided by the Radio Communications Foundation. To support radio amateurs to try practical skills themselves or to put on their events, the RSGB has published a new section on its website that is dedicated to practical events. You'll find a guide to running a buildathon, detailed information from the MCU workshop as well as a short video to inspire you! Feedback from the RSGB's events has been wholly positive with requests for similar activities around the country. Could your club host an event and perhaps even boost its numbers at the same time? Find out more at rsgb.org/practical-events The RSGB Awards Manager has announced that, with the support of the Board, he has added new categories of achievement to the IARU Region 1 Award. These include WARC bands only, 10MHz only, 18MHz only and 24MHz only. The standard IARU Region 1 Award check spreadsheet should continue to be used for these categories. However, award chasers are advised to keep separate versions for each band or set of bands. There are no mode or power restrictions and there is no distinction between fixed and portable stations; you just have to be operating within the same country for all QSOs used in the application. There aren't any limitations on the start dates for the awards other than the dates for particular countries as identified in the check sheet. This reflects, for example, when a country became a member of the IARU. The RSGB would like to thank the award chasers who contributed to the discussions about adding new categories. With just two weeks to go until Youngsters on the Air Month, operating slots for GB24YOTA are fast filling up.

Using FT4 on the 80m to 10m bands, where contests are permitted, the exchange is a signal report. On Tuesday, the 19th of November, the RSGB 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator. On Thursday, the 21st of November, the RSGB 70MHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. The CQ World Wide DX CW Contest starts at 0000UTC on Saturday the 23rd of November and ends at 2359UTC on Sunday the 24th of November. Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of November. The solar flux index took a downturn this week, ending up at 150. The visible solar disk is looking rather bare compared with a couple of weeks ago. This is the lowest SFI value since the 2nd of May 2024, but it is only a matter of time before we see another sunspot appear as we make our way through solar maximum. The good news is that we have been pretty devoid of solar flares and coronal mass ejections, with only a few M-class flares occurring. Any CMEs were not Earth-directed and so the Kp index stayed low. As a result, the bands are still playing ball. A quick look on 10 metres at 10.00UTC on Thursday the 14th showed the 4X6TU (Israel), OH2B (Finland) and LU4AA (Argentina) International Beacon Project beacons were romping in on 28.200MHz. Going down to 15 metres it was even better, with ZL6B (New Zealand), VK6RBP (Australia) and JA2IGY (Japan) all audible on 21.150MHz. Also, the proton flux from the Sun remains low, which bodes well for polar paths. Next week the Space Weather Prediction Centre forecasts that the solar flux index will rise again, no doubt as new or returning sunspots appear, perhaps putting us into the low 200s. From a geomagnetic perspective, unsettled conditions are forecast for Wednesday, the 20th of November when the Kp index could rise to four. Looking further ahead, fingers crossed for the 23rd and 24th weekend when the CQ Worldwide CW contest takes place! And now the VHF and up propagation news from G3YLA and G4BAO. It was more of the same on 50MHz last week, with what may be a mix of Es and F2-layer propagation producing morning openings in the afternoon to the Gulf States, Southeast Asia, and the Americas. On the higher bands, with the high pressure just hanging on in its colder guise, next week looks distinctly on the wintry side for some areas. The high pressure has, along with its predecessor, given us at least two weeks of Tropo conditions on the VHF bands. The expected change-over to low pressure takes place on Sunday and drives a colder northerly weather pattern down across the UK, even to southern areas. This means that the majority of next week is a good time to look for rain scatter. Regarding meteor scatter, the peak of the Leonids occurs today, the 17th of November, with rates of 15-20 per hour. Also, occasional peaks of the Kp index above four should tempt us to beam north for chance aurora openings. As usual, check the VHF beacons and clusters for signs of activity during the afternoon and evenings when the auroral oval is displaced southwards nearer to our part of the world. It's a good week for EME operators, the Moon reaches peak declination on Monday morning, but path losses are rising as we have passed perigee on Thursday the 14th. 144MHz sky noise is moderate, reaching 500 Kelvin on Sunday night. And that's all from the propagation team this week.

Foundations of Amateur Radio The hobby of amateur radio is one of experimentation and change. For decades this came in the form of circuit diagrams, components and scrounged hardware from anything that wasn't bolted down. New functionality came with the aid of a soldering iron. More recently, functionality comes from participation in the global electronics market where you can buy any radio you like and have it shipped to your door within hours at an unbeatable price. Mind you, buying all those unbelievably cheap radios does start adding up and if you want to use more sophisticated hardware, that too is possible, at a price, somewhere between $50 and a new Porsche. Whilst that's an option for some, for the rest of us, there are better and cheaper ways. Of course it doesn't stop there. If you connect any radio to a computer, you can use whatever software you like to encode and decode any signal you can imagine. With a traditional radio connected to a computer you can make it participate in hundreds of different so-called digital modes. Before I continue, let's look at radio in a slightly different way. Consider an antenna as a continuous source of voltages that are amplified, filtered and demodulated in some way by a radio. You can think of the combination of antenna, radio and computer as a stream decoder. To decode a signal in a new way requires a new decoder, which you could build from components or as I've said, buy online. During the week I've continued experimenting with GNU Radio. If you're unfamiliar, it's a toolkit that allows you to build so-called flow graphs that can process a signal stream. Think of it as a box of Lego that you can put together to build any type of decoder. Let me say that again. Imagine that you want to decode or transmit a mode like FreeDV, M17, APRS, Olivia, Contestia, or Hellschreiber. With the GNU Radio toolkit, all of this is possible and you won't need to buy new hardware or bust out the soldering iron every time you want to experiment with a new mode. If you have been playing with digital modes already, you'll likely point out that you can already do this today by using software running on a computer, and that's true. What that doesn't tell you is that this comes with a very specific limitation, namely that all those modes require that they fit inside a single audio channel because all those digital modes you might be familiar with are essentially using an SSB or FM signal with the audio generated or decoded by a computer. Even if you have a modern radio like for example an ICOM IC-7300, you'll still be limited in what modes of transmission you can make. ICOM limits the transmit bandwidth to 2.9 kHz. Flex Radio appears to double that to 7.9 kHz, but numbers are sketchy. The point remains, most current amateur radio technology is based around the notion that a mode essentially fits within a single audio channel and a very narrow one at that. So, why does this matter? If you run out of FT8 space on a band, right now you need to change to an alternate frequency to play, but you'll only be able to see the stations that are using the same alternate frequency, as long as they fit within the bandwidth of an audio signal. If you wanted to check out the main frequency, you'd have to change frequencies and keep switching back and forth. Using this idea, monitoring all of FT4, FT8, WSPR and all CW beacons, all at the same time becomes unimaginable, not to mention costly if you needed a radio for each band and each mode. What if you wanted to use another mode that took more than about 4 kHz, like say a 5 MHz wide DVB-T signal which you could be experimenting with on 70cm? Or, what if you'd like to compare a repeater input with its output at the same time? Or compare two repeaters together? Or find the best band to operate on right now? The point being, that there are things that simply don't fit within a single audio channel that you won't be able to play with using a traditional radio. As it happens, that too is a solved problem. Remember that I mentioned that you can think of an antenna, radio, and computer combination as a stream decoder? What if I told you that an SDR, a Software Defined Radio, is essentially a device that translates antenna voltages into numbers which you can process with GNU Radio? Whilst that does imply replacing your radio, you don't have to jump in at the deep end to start playing and even if you do decide to buy new hardware, you can get your toes wet with all manner of self build or commercial kits. Even better, you can start with the gear you already have today and become familiar with GNU Radio and when you're ready to expand your station, you can add in an SDR and continue to use the same tools to experiment. Not only that, you can do interesting things by combining what you already have. Consider for example the idea of using an RTL-SDR as the receiver with a traditional radio as the transmitter. You could decode all of the FT8 signals on a band and transmit where there was space to do so. The point being that you can do this one step at a time. Every time you download or build another GNU Radio flow graph, you can have a new decoder and as time goes on, you'll be able to decide what hardware you might want to pair it with. To be clear, I'm talking about the gradual change from component based radio using audio interfaces into software based radio. It's not like we haven't done this before. Anyone recall spark gaps, or valves? The future of experimentation is bright and it's filled with bits. I'm Onno VK6FLAB

Foundations of Amateur Radio One of the unexpected benefits of this hobby is how it provides you with the ability to connect to others in ways that are not directly related to radio. Take for example Steve. Steve appears at unpredictable times and locations, been hunted by citizens and scientists and unlike Steve's potential invisible cousin, the proton arc, has been photographed by aurora hunters many times. It looks like observations go back as far as 1705. In 2017, physics professor Eric Donovan saw some of these photos and got curious. Assisted with GPS coordinates from an aurora hunter in Alberta, Song Despins, Eric correlated the time and location and it turns out that Steve was observed as a ribbon of gas 25 kilometres wide, 300 kilometres above Earth with a temperature of 3,000 degrees Celsius by the European Space Agency's Swarm, a constellation of magnetic field measuring satellites in orbit since 2013 and planned as a four year mission, so-far it has almost managed eleven years. Steve? Yeah, it's not named after Steven Hawking or Steve Martin, rather, if you're seeing something unexplained, you might name it something less scary, like the hedge in the movie "Over the Hedge". Steve was given a backronym, finding words after the fact, Strong Thermal Emission Velocity Enhancement, but I prefer Steve. The NASA team at Goddard Space Flight Center have adopted Steve, so it looks like a keeper. I would never have even stopped to read the recent article in the local news, let alone dig into the various publications, if it weren't for the notion that Steve is one of many phenomena affecting the ionosphere and with it our hobby. Here's another example. Vance KV4P published a plan on kv4p.com, outlining a $35 project that requires minimal soldering that makes any Android phone into a handheld radio for 2m. Using a radio module, a micro-controller, a short USB cable, antenna connector, antenna and some sticky gel pads, Vance has come up with an open source project and circuit-board design that will get you on your way. He's even designed a 3D printable enclosure so you don't have to scare your friends with a bare circuit board. Whilst the Android app is in beta, that is, not quite fit for human consumption, you'll need to drop an email to Vance to get in on the action. Source code is on GitHub. I came across this project after breakfast, reading the "Y Combinator - Hacker News" which features all manner of weird and wonderful projects, links and questions from all over the technology sphere. The post has expansive discussion on Vance's project, including thoughts on other ideas on how to do interesting things related to our hobby. Again, if it weren't for the fact that I'm already an amateur, I would never have taken more than a glance at this and I would never consider that this was a doable project, let alone discover other amateur radio projects like HamWAN and AREDN, or the Amateur Radio Emergency Data Network. The point being that we as amateurs are often pigeonholed by society into the idea of obsolete, disconnected and quaint. I'm here to tell you that our hobby has made me more alive than ever, more connected to others around me, more observant to electrical and physical phenomena and if that makes me quaint, I'm Okay with that. Also, while we're on the topic of being Okay. Charles NK8O reached out and told me that after listening to me talk about FT8 and his Morse code achievements, he cracked up and then raised the stakes by pointing out that you can get on HF with CW, that's continuous wave, or more commonly, Morse Code, for about $100, where a kit capable of SSB, Single Side Band, or more generally audio, will likely set you back significantly more. His advice, which I cannot fault, "Get on the air!", presumably to make some noise. I'm Onno VK6FLAB

Foundations of Amateur Radio Every now and then you come across an idea that throws you for a loop. It comes seemingly out of nowhere and once you've seen it, you cannot unsee it. It's a lot like a 1929 painting I like called "The Treachery of Images", also known as "Ceci n'est pas une pipe", or in English, "This is Not a Pipe" by Belgian surrealist painter René Magritte. If you're not familiar with it, it's a painting of a pipe, and by being a painting, it's not a pipe. Obviously. Before I go into the idea that rocked my world, I need to set the stage a little. There are several modes I've discussed before, WSPR, or Weak Signal Propagation Reporter, FT8 or Franke-Taylor design, 8-FSK modulation and plenty others. Each of these modes has one thing in common. They require that all participants are using the same time. That is, both sender and receiver need to agree on when "now" is for this to work. A WSPR signal takes 110.6 seconds, every 120 seconds, starting on the even minute. It requires that the transmitter and receiver agree on the time within about 2 seconds. An FT8 signal takes 12.6 seconds within a 15 second window. It requires an accuracy of about 20 milliseconds. These timekeeping requirements are pretty easy to achieve in a modern network connected computer. You turn on a thing called NTP, or Network Time Protocol, point it at an appropriate clock and off you go. If you're not connected to the Internet, then things get squirrelly pretty quickly. You could buy yourself a GPS, set up a link between the GPS and your computer, run some software and use the GPS clock to synchronise time on your computer. Of course, this requires a GPS, a serial cable, software, configuration, battery power to keep the GPS running and probably a couple of other things. I've never done this, but given what I'm about to share, I don't think I ever will. What if you used a WSPR, or an FT8 signal, from someone else to synchronise your clock? If you've ever launched WSJT-X, you'll have seen a column marked DT, that's Delta Time, or the difference in time between the clock on your computer and that of the transmitter. If you could read the difference and use it to adjust your clock, you'd be in business. Charles NK8O pointed me to a GitHub Gist with a single little Python script, written by Peter K6PLI. It updates the clock on your computer using the Delta Time from WSJT-X. I'd point you at the script from here, but 3a730575, and 24 more characters, and that's just one element of the URL, doesn't run quite off the tongue, so I've cloned it into my VK6FLAB GitHub repository where it's called wsjt-time-sync. I added Peter's description to the ReadMe file, but I can take no credit for the effort, or the idea, that's all Peter. So, synchronise your clock using the signal that you're trying to decode. Seems pretty obvious now, but that was a brand new notion for me. Of course now I'm excited and wondering where else I might use this. Let me know if there's more to this that tickles your fancy. Also, just because I know Charles will poke my eye out with a Morse key if I don't mention this, you could use this script on your next POTA, Parks On The Air, or WWFF, World Wide Flora and Fauna activation, or anywhere else you go portable to make some noise. I know, right, Charles, using FT8 instead of Morse Code, what's next, the end of the hobby? I'll tell you a secret. From time to time, he even uses his voice! I'm Onno VK6FLAB

This is The DX Mentor podcast. I hope to help those hams trying to move up the DXCC ladder as well as those that at on the DXCC Honor Roll. As fast as technology is moving, no one can keep up on it all. I am here to help. #DX #Hamradio Our guests today are Rolf, DL7VEE, Christian, DL6KAC, and Joe, W8GEX. We are going to be discussing the upcoming DXPedition to C21MM, Nauru with Rolf and Christian. The DXpedition to Nauru, C21MM, will run from October 10th, 2024 to October 29th, 2024. I normally don't do this, but from the Daily DX, I can share the following information, which is essentially what we discussed in the first 12 minutes: With less than 4 weeks to go, the team of 14 German operators are ready. We follow our main principles being light-weight and cost effective. As always, only transceivers from Elecraft will be used. All equipment including antennas will be transported by the team members using “traditional luggage” partly oversized. However, this does not mean that we compromise on the antennas. For the high bands we are going to use our 2-element full size wire beam from LZ Antennas. That provides us with some dB more gain compared to a vertical. By using the LBS Pentaplexer we can operate 3 high bands together at the same time on this antenna. As always, we follow our strategy to use resonant and full-size single band antennas on all bands (except 160 m). No grounded verticals will be used. Verticals with an elevated radial are even better for reception, also known as Up & Outer. This time we will carry two 22 m (72 feet) Spiderbeam fiberglass poles for 160 m & 80 m (compared to 18 m poles on our last DXpeditions). That is perfect for 80 m and an improvement for the top band as well. We will also bring the brand new 14-m-HD-fiberglass pole from Spiderbeam which gives us 2 m more height compared to the 12-m-HD-pole. This one is perfect for bands from 60 m and up. For low band receiving we plan BOGs. Jan, OK2ZAW (QRO.CZ), supported us with RX band filter boards for splitting one BOG to different receivers on different bands. For 40 & 30 m we try loops this time. We always use small band pass filters for each band between transceiver and amplifier and additional bigger band pass filters to the antennas. We will run our proven shift system with radio and free time slots 24/7, ensuring that our experienced operators will have full concentration in their shift. 5 stations between 160 and 6 m in CW, SSB, RTTY and FT8 are planned. Starting with a first group of 6 men from October 10th only on high bands for few days. Second part of the group will arrive October 15.

I picked up the DigiRig DR-891 sound interface, which is specifically made for the Yaesu FT-891 radio. The FT-891 doesn't have its own built-in sound card, so this interface is a great step towards making the FT-891 plug-n-play. Let's take a look at how to set this up and how simple it is to make FT8 contacts from POTA with this DigiRig.Today's video is sponsored by Ham Radio Prep - save 20% off of all course with code jason20Links to items in video:DigiRig DR-891 - https://digirig.net/product/digirig-dr-891/p/1/Yaesu FT-891 - https://amzn.to/3ASD8NVReel POTAable Antenna - https://reelefhw.com/Panasonic FZ-G1 Toughpad - https://amzn.to/4cF3lwVBecome a supporter of this podcast: https://www.spreaker.com/podcast/ham-radio-2-0--2042782/support.

Foundations of Amateur Radio Internet access across HF radio In the mid 1980's there was this thing called a Bulletin Board System or BBS. You would connect your computer to a gadget called an acoustic coupler that you would sit next to a telephone. You'd pick up the handset, dial a phone number and wait until there was a squeal in your ear. Then you'd push the handset into the rubber cups on the coupler and watch as your computer started putting characters on your screen. Now, truth be told, my first foray was the next generation of this, an actual modem where you didn't actually have to touch the telephone, instead, the device could dial on your behalf using so-called AT commands. And if we're being totally honest, I never actually connected to a BBS. My adventures with global communications started with Usenet News in 1990, but I'm here to make a point, I promise. Amateur radio is a hobby that is for experimentation. One such experiment is a thing called packet radio. Before you roll your eyes about ancient technology, this gets very cool, very fast. At its most basic, packet radio is about digital radio communication. Until not that long ago to play you needed a thing called a TNC or a Terminal Node Controller. When I got my license in 2010 I was told that this was a magic box to make digital communication possible between a radio and other radios and amateurs. Right now, many people are playing with WSPR, Weak Signal Propagation Reporter as well as FT8, both examples of things intended to get specific chunks of information exchanged between two stations. What if I want to chat, or send a file, or a picture? There are tools like "js8call" which is experimenting with the idea of using FT8 to chat, but what if I told you that there's a better way? Written by John WB2OSZ, named after a canine that became extinct 9,500 years ago, "direwolf", is software that implements an expensive piece of 1980's hardware, a TNC, that runs just fine on a $5 Raspberry pi. It's been around for over a decade, the oldest date I can find is March 2013 though undated versions before that exist. It's an example of a so-called software-modem, simple to get started, and it implements the essential pieces of packet radio. It's currently running connected to my radio and I can see packets of information scrolling past. In this case I'm tuned to the local APRS, or Automatic Packet Reporting System frequency of 145.175 MHz. It's the same information that you can see if you point your web browser at aprs.fi While that's great, it's just the beginning. Tune to another 2m or 70cm frequency and you can use it to connect to a BBS being run by a local amateur, or, you can tune to a HF frequency and connect to one run somewhere else. Direwolf also supports a technology called KISS, Keep It Simple Stupid, yes really, developed by Brian WB6RQN, Phil KA9Q, Mike K3MC and others. KISS allows you to connect a modem, like direwolf, to a computer and use technologies like TCP/IP, the primary language of the internet, across a radio link, any radio link. Let me say that again with different words. You can use your HF radio to browse the internet. No proprietary modes in sight, weak signal, error correction included, all open source, all free, all ready to go. While we're singing its praises, direwolf can also act as an iGate, an interface between radio and services like aprs.fi, a digipeter that receives and re-transmits APRS data and plenty more. It gets better. What if you wanted to use something like RTTY, PSK31, Olivia or some other mode? You could use "fldigi" instead of direwolf since it too supports KISS. To be fair, there are lots of moving parts here and I've glossed over plenty. This isn't intended to discuss precisely how to do this, rather that it's possible at all and has been for quite some time. I can't wait to attempt to browse the internet using my radio, for nothing other than the thrill of attempting it. I wonder if I can do this with Morse Code as the underlying protocol. Only one way to find out. I'm Onno VK6FLAB

Foundations of Amateur Radio So, I have a confession. I don't know everything. Shocking right? Over the past too many months, actually, come to think of it, years, I have not been on-air with my station on HF using FT8 or Olivia, modes that use tools like "WSJT-X" and "fldigi". This has not always been the case. For a time I used a tiny computer running those tools. It had plenty of issues related to its size and capacity. Overwhelmingly it was slow, unsurprising since it was released in 2009. After one particularly frustrating session where I had to recompile WSJT-X on an older 32-bit operating system using an Atom processor, I decided that this was not helping me, and I put it away. The idea was to use my main computer that could do all the heavy lifting without cracking a sweat. To make this happen the traditional way, I'd be expected to physically connect the radio to the computer. I'm not a fan of doing that, given the potential damage that RF could do to my computer, not to mention that I have a sit-stand desk on wheels that I move around my office as the mood or the light takes me, if you're interested, I found a mobile lectern that the computer is clamped to. Works great, been using it for years. RF aside, moving around the office is not conducive to plugging in a radio that comes with power, coax, audio, control, microphone and expects to have some space around it to actually use it. No problem, I have a RemoteRig, a device that comes in two parts. You connect one unit to the radio, the other to the head, that is, the removable faceplate of the radio, and using a network connection, you can have the head in one place and the radio in another. The two units don't have to be in the same room, let alone the same country. I figured that I could replace the second half of the system, the head and its unit, and instead use software on my computer to get the same functionality and be up and running in minutes. That was several years ago. Interestingly, whilst I'm putting this together I did a search for "RemoteRig protocols" and learnt a few things, so perhaps this path isn't quite as dead as I feared. I've reached out to Mikael SM2O and if that comes to anything I'll let you know. In the meantime I've been trying to figure out how to operate my radio in software only. I can control the radio if I physically connect a computer like a Raspberry Pi to it and use "rigctld" to interact with it. This gives me access to all the standard CAT, or Computer Assisted Tuning commands. In other words, I can change band, mode, frequency, trigger the transmitter, all the stuff that you need to get on-air to make noise. There's only one bit missing, the noise, as-in audio, either coming from the radio, or going to it. I suppose I could trigger a carrier and use it to send Morse, but that doesn't give me receive capability. I've tried using network audio using "pulseaudio" - it never worked right. I've made USB hot-plug scripts that allow you to connect a USB device into a computer and access it across the network on another computer - it mostly works for sound, but reliable is not a word I'd use. I've looked at using the USB sound card in the audio mixer on my desk, but it's subject to all manner of funky restrictions and random audio dropouts. I could use a virtual screen and connect to a Raspberry Pi that's physically connected to the radio, but that's leaving all the hard work on the Pi, rather than the computer that I'm currently using with several orders of magnitude more capability. Whilst we're discussing this, one of the reasons I like the idea of a software defined radio like a PlutoSDR, is that the stuff coming out of the radio, and going into it for that matter, is already digital. It takes away a whole lot of complexity, admittedly replacing it with software, but that's where I feel more comfortable. Which brings me to you. As I said, I don't know everything. What are you doing in this space? Are you actually on-air with your contraption, or is it still in the planning stages? Are you sending audio, or digital data across the network? Does your system have the ability to swap out a radio and replace it with something completely different? Do you rely on functions available on the radio, or could it be used for a 1950's valve radio, a twenty year old one, a current model, or any number of software defined radios without issues? Finally, is it Open Source? I confess that I'm not holding my breath for an answer, but there is a chance that you're similarly intrigued by this collection of questions that you will poke your head above the fence and make yourself known.

As fast as technology is moving, no one can keep up on it all. I am here to help. #DX #Hamradio The W8S DXpedition to Swains took place October 4th to the 17th, 2023. The 10 operators made almost 90,000 QSOs on 160 – 6 meters on CW, SSB, RTTY, and FT8. Our guests today are Adrian, KO8SCA, Johannes, PA5X, and Joe, W8GEX. This past weekend, the W8S DXpedition was recognized as the 2023 SWODXA DXpedition of the Year! At that time of this recording, we did not know that this group would be the DXpedition of the Year. "From October 4, 2023 until October 17, 2023 an international team of 10 operators will be active from Swains Island as W8S. QRV on all HF bands in CW, SSB, FT8 and RTTY with 6 stations from 2 separated camps." Introductions W8GEX – Joe went to Swains in 2012. He is the co-host. I think this will be a great conversation.

Foundations of Amateur Radio Much is made in our hobby about working DX, that is sending and receiving distant radio signals. How distant is up for debate. Depending on where you are, DX might be outside the continent, outside the country, or in my case you could easily say, anything outside of my state, since the nearest border is about 1,240 km away from here. For giggles, the distance between Albany in the South West and Wyndham in the North East of the state is 2,400 km and that's via radio wave. By car it's 3,570 km. To be clear, we're still inside VK6. All that to say, DX is in the ear of the beholder. If that's not enough, there's a group of amateurs who are of the strident opinion that for DX to count it must be a two-way contact. That is, both stations need to hear each other and as such, those amateurs believe that a mode like WSPR, the Weak Signal Propagation Reporter can't possibly be considered DX, even if you can discover that your station was heard on the other side of the planet. I'm going to skip right over those who tell anyone who will listen that FT8 isn't real radio because it's just computers talking to each other. This to give you some context when I introduce the next idea, namely FM Broadcast DX. I'm acutely aware that this isn't amateur radio, there's no two-way communication, it's probably not DX and besides, it's computers. That out of the way, let me tell you about something I discovered. Many, but not all, FM broadcasters transmit multiple signals when you tune to their station. One of those is a signal called RDS, or Radio Data Systems. It's used to show you the name of the station, sometimes what song is playing, what style of station it is and other information like road traffic alerts and emergencies. You can decode this using an RDS decoder. Recently I was browsing YouTube. I came across a video on the Broken Signal channel that digs into the world of FM-scanning to log any RDS information for the purpose of finding DX stations. The video goes into great detail on how to set this up with Windows, by copying files into various places, updating XML files, configuring sample rates, connecting virtual audio cables, running several tools simultaneously and it goes on to demonstrate how this all hangs together. While I was impressed with the idea, the implementation didn't speak to me, since I wince at the notion of copying random files into an application installation directory and besides I'm a Linux user. So, I went hunting. Turns out that there is an RDS decoder for Linux, called "redsea", written by Oona OH2EIQ. It's on GitHub. Compiling it is pretty straightforward, follow the instructions and it should work as advertised. You'll also need to have "rtl-sdr" installed so you can run a tool called "rtl_fm". Again Oona's instructions should help you out. I will add that I'm assuming that you have a so-called RTL-SDR dongle, it's a cheap USB device that can be coerced into pretending to be a software defined receiver with about 2.2 MHz of bandwidth. Based on the example shown, I immediately tuned to a local station and RDS information started filling my screen. To let you know how simple this is, you run the "rtl_fm" tool and send its output to "redsea" which decodes the information and displays it on the screen. That's it. No more moving parts, no XML files, no shenanigans with virtual audio cables and the like. Stage one complete, on to stage two, scanning. The "rtl_fm" tool has the capability to scan a range of frequencies. I tried this, but didn't really get anywhere, since for the scanner to work you need to set the squelch in order to switch between frequencies, but if you're aiming for a weak signal, it will never be heard if your local FM broadcasters are belting away 24 hours a day. So, instead I'm scanning each frequency between 87 MHz and 109 MHz, every 10 kHz, for 10 seconds, to see if there's any RDS data to be heard. I send that to a file and when I feel the urge, I can go check to see what I've heard. I haven't yet put this up on GitHub because I'm considering making it a contribution to the "redsea" project instead of a project of my own. Now, at this point you might wonder what all the fuss is about. Well, the same method could be used to decode your local amateur repeater idents, or the NCDXF beacons, or any other kind of interesting information. I saw one user link "rtl_fm" to "multimon-ng", a tool I've spoken about before. You should also check out Oona's website, windytan.com, there's a whole range of signal processing stories to be found, including dealing with flutter distortion on Steamboat Willie and a very cool spiral spectrogram. I'll leave you with one question. Why haven't you installed Linux yet? I'm Onno VK6FLAB

Linus Balsys, LY2H, dives into the fascinating realm of field operations in his native Lithuania, QRP techniques, Morse code, digital modes, and much more. Linus talks about his  exploration of the great outdoors with park activations, hillfort castles, chases awards, and delves into satellite communications. From his Renault Trafic campervan equipped with cutting-edge ham radio gear like the Icom IC-705 and the QRP-Labs QMX.  Linus showcases the innovation and affordability of modern equipment. In addition, Linus shares how ham radio skills have practical applications in daily life, from repairing electronics to enhancing relationships. Hear about his efforts to rejuvenate the ham community in Lithuania, attracting young enthusiasts through contests, digital operations, and educational classes. Linus also highlights the dual thrill of ham radio: the leap in technology with Software Defined Radios (SDRs) and the invaluable role of amateur radio in emergency communications, echoing its historical significance. Tune in for a journey through the intriguing and impactful world of ham radio with Linus Balsys, L2YH. in this QSO Today.

Paul Barnes, W4YRL, now a ham for over 65 years, enjoys FT8, CW, and getting on the air with modest wire antennas.  Paul has traveled to over 50 countries and enjoyed operating from abroad. He credits the hobby for a happy career in electronics focused on simulators for space, military, and nuclear power plants, and for the life long friends that he has made along the way. W4YRL is my QSO Today.

Charles Powell, NK8O, would argue that an early interest in radio and communications aided him in making a transition from professional French Horn player to pediatric doctor rather than suffer the mid-life crisis.  Charles likes just about everything that ham radio offers including POTA, CW, kit building, old rigs, and operating his own DXpeditions from exotic locations around the world.  NK8O and I discuss these topics and more in this QSO Today.

Richard Gutknecht NZ2I, is a second generation amateur radio operator, catching the bug at an early age and getting the Novice license at age 15. Answering his country's call to duty, Rick joined the Air Force and became an active ham while stationed in Germany.  Now retired, Rick enjoys getting on the air, volunteering for his amateur radio club, and now producing and co-hosting a podcast on current events and American history.  NZ2I is my QSO Today.

Foundations of Amateur Radio The attraction to amateur radio for me lies in the idea that it provides a framework for experimentation and learning. There's never an end to either. Each time you go on-air is an opportunity to do both and every chance I get, I cannot help being sucked into another adventure. My weekly scribbles are an attempt to both document what I've been up to and to encourage others to take a step on the path that I'm discovering, moment by moment, week by week. One of the more, lets call it, comment inducing, activities I like to explore is low power operation. This is not to the liking of many operators who are happy to run their shack at full legal power. For me, full legal power is 40 dBm, or 10 Watts. That's not to say that I've never experienced the thrill of running a pile-up on a contest station, I have. What's not to like? You speak with people from communities far-and-wide, they're clamouring to talk to you and making contact is pretty easy, almost effortless. The lure towards more power, bigger antennas, more bands and more radio is always there, but it's not all there is to this hobby. My year-long efforts of running a 10 dBm, or 10 mW, Weak Signal Propagation Reporter, or WSPR, beacon, is evidence that you can make it 13,945 km from me in VK6 to PA where it was heard by Jaap, PA0O in Zuidwolder, just outside Groningen in the North East of 't kikkerland. In fact, across 2023, my 10 dBm beacon was reported 4,849 times by 58 stations, many inside Australia, but there were reports from Indonesia, Japan, New Zealand, Taiwan, Antarctica, Sweden, and as I said, the Netherlands. One of my friends, Charles NK8O, is a mostly mobile operator who loves to set up for both Parks On The Air, also known as POTA, as well as World Wide Flora and Fauna, WWFF. His chosen mode is CW, but you'll find him using digital modes like FT8 and even as a rare DX event you might strike it lucky and hear his voice. Most of his activity uses batteries, so you'll rarely make contact with him when he's using more than 47 dBm or 50 Watts. A couple of weeks ago during the weekly F-troop net he announced that for the duration of 2024, Charles intends to operate using low power, or QRP. Operating QRP isn't for everyone, but I'd hazard a guess that if tried, there's plenty to learn and experience by dialling the power down to play in a low power environment. Think of it like this. If you're into cars, it's the thrill of driving fast. It's not the only way to drive and enjoy yourself. Driving sedately, touring the back roads, will get you to your destination just as well and along the way you'll have the opportunity to look out the window, to even have the window down and to enjoy the environment, rather than spending every second being on a hair trigger. If fishing is more your thing, high power radio is like dynamite fishing. You'll easily catch all the fish in the pond, but once you have, there's nothing left to do. Fly fishing on the other hand gets you a different but perhaps just as satisfying experience. So, if you've never done this QRP thing, what can you expect when you turn the power down? First of all, reception works just the same. So, everyone you heard before will continue to be heard. Transmission is going to be a little different. If you've ever changed over radios you might already have experienced the jolt between what you can hear and what you can work which can differ significantly between two radios. If you're used to high power operation, you'll essentially work most stations you can hear, but when you're using low power, there's going to be stations that you have little or no chance to work. Most of those are obvious so-called alligators, all mouth, no ears. That said, plenty of loud stations have years of honing their skill and station and your QRP call can just as easily be heard as the next station. You'll likely sharpen your calling skills. There's no point in calling when other stations are blotting out your call, so you become adept at dancing around other signals. You'll spend more time considering propagation and the best band to make your signal count. Another side effect you'll likely notice is less wear and tear on your gear. There's also little chance of having RF inside your shack upsetting your computer, or getting complaints from the neighbours who happen to have a crappy TV that stops working as soon as you key up. If you make mistakes, your station is more forgiving and less likely to be damaged when an unexpected fault occurs. Speaking of faults. The other day a coax switch in my shack caused my radio to stop transmitting. Luckily with the power setting at its lowest, there was no permanent damage. After testing with a multimeter I discovered that it shorted the centre pin to shield in one position. When I opened up the switch, I discovered that the blade that gets moved between ports had become slightly twisted, which in turn caused it to ground against the body. A slight turn with some needle-nose pliers fixed the problem, well, at least for now. I have begun searching for alternatives in earnest. I am quite taken by the notion of building my own switch from relays and controlling those via a network connection. More research and experimentation is needed because there's plenty I don't know about this subject. Between you and me, it's never too late for another experiment and I'd encourage you to spend some time testing the QRP experience and given the current state of the solar cycle, there's no better time than right now.

Is Ham Radio a natural hobby for Linux users? An old friend joins us to explain where the two overlap. Special Guest: Noah Chelliah.

We take a "Rust-only tools" challenge for a week and admit what worked, and what sucked. Plus, a surprise guest.
