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 A recent comment by a fellow amateur sparked a train of thought that made me wonder why there is a pervasive idea within our community that you need a radio transmitter and antenna to be a radio amateur, moreover that for some reason, if you don't have either, you're not a real amateur. I suppose it's related to the often repeated trope that the internet enabled modes like Allstar Link, Echolink and even IRLP, are not real radio, despite evidence to the contrary. Instead of fighting this weird notion, I figured I'd get on with it and find a way to play even if you don't currently have the ability to erect an antenna or key a transmitter for whatever reason. Before I dig in, a WebSDR is a Software Defined Radio connected to the Internet. It allows a user to open a web browser, pick from a massive collection of receivers around the world and listen in. Some of these also have the ability to transmit, but more on that later. Here's the idea. Have you ever considered tuning to a WebSDR, using it to pick a signal and using your computer to decode that signal? I'm aware that some sites provide a range of in-built decoders, but that doesn't cover the wide spectrum of modes that amateur radio represents, let alone the modes that are not specific to our hobby. As I've said previously, many of the modes in use today are essentially the width of an audio stream. This means that if you tune a WebSDR to a frequency the audio comes out of your computer speakers. If that's voice, your job is done and you can hear what's going on. If it's something else, then you're going to have to find a way to decode this to get the message. So, if you send the audio from your web browser into something like Fldigi or WSJT-X, you'll be able to decode the signal if it's supported by those tools. This is true for all the other tools too, Morse, RTTY, you name it. Depending on which operating system you're using the way to implement this will differ. Starting with a search for "WebSDR and WSJT-X" will get you on your way. You might ask why I'm advocating WSJT-X, even though it only supports a small set of modes and that's a fair question. In my experience, it's the simplest to get running and get results. Two tips, make sure you set your configuration to indicate that you don't have a radio, otherwise it's going to attempt to control something that isn't there, and make sure that your computer clock is set accurately using NTP or Network Time Protocol. You can thank me later. Now I hinted earlier at transmitting. There's a growing range of places where your amateur license will give you access to a station somewhere on the internet and with that the ability to get on air and make noise. An increasing number of radio amateur clubs are building remote stations for their members to enjoy. There are also individuals and small groups doing the same independently. A few organisations are offering this as a service to paid subscribers. These tools often implement a remote desktop session where you connect to a computer that in turn is connected to a radio. The supported modes depend on what is installed at the other end. Others implement a slightly different method where you run specialised software locally, sometimes inside a web browser, that connects to a server across the internet, allowing you to run whatever digital mode you want on your own computer. I'll point out that even if you start with receiving digital modes using a WebSDR, you can expand that into transmitting at a later stage. So, no antenna, no transmitter, no problem, still an amateur! I'm Onno VK6FLAB

  GB2RS News Sunday, the 27th of April 2025   The news headlines: RSGB delegates attend special IARU Region 1 Interim Meeting in Paris Join the RSGB in celebrating World Morse Day Be part of the RSGB's team at the Youngsters on the Air summer camp The RSGB is participating in the International Amateur Radio Union Region 1 Interim Meeting in Paris this weekend. The event is of particular historical significance as it coincides with the centenary of the founding of the IARU in 1925, as well as the 75th anniversary of the establishment of IARU Region 1 in 1950. The French host society, REF, is also marking its 100th anniversary. This year's meeting in Paris reflects a broader scope than in previous years and, for the first time, includes ‘Youth Matters' on the agenda. It also covers the usual focus areas of HF, VHF, UHF and Microwave, as well as Electromagnetic Compatibility. The RSGB has been a key contributor to the meeting, submitting papers that include future options for the 23cm band and the harmonisation and protection of HF bands. Three delegates from the RSGB are attending the meeting in person, including the newly appointed RSGB President Bob Beebe, GU4YOX. There will be eight other RSGB representatives attending remotely. The meeting serves as both a celebration of amateur radio's rich heritage and a forward-looking forum to address the challenges and opportunities facing the global amateur radio community. You can view meeting documents at conf.iaru-r1.org  In celebration of the centenary of the IARU the RSGB has created a web page to share information about its part in the celebrations. This includes a link to an RSGB archive video from the IARU meeting in Paris in 1950, as well as the RSGB's July 1925 T & R Bulletin that contains an announcement detailing the formation of the IARU. Go to rsgb.org/iaru-centenary for further details. Today, Sunday the 27th of April, is World Morse Day. The day honours the birthday of the inventor of Morse code, Samuel Morse, who was born on this day in 1791. To celebrate the occasion, the RSGB has released a video with a question in Morse code for you to answer. Once you have used your Morse skills to decipher the question, get involved by leaving your answer in the comments section under the post. You can view the video on the RSGB YouTube channel via youtube.com/theRSGB or search for @theRSGB on Facebook or X.

The RSGB Exams Quality Manager would like to remind everyone that clubs can still run exams if they are a Registered Exam Centre. Exams will be conducted online unless a candidate has a special requirement for a paper exam. The introduction of remote invigilation to allow people to take an amateur radio licence exam in their home does not affect this. If clubs have any queries about delivering exams, they should contact the   RSGB Examinations Quality Manager, Dave Wilson, M0OBW, via eqam@rsgb.org.uk. If anyone has special requirements for an exam, they should contact the RSGB exams team via exams@rsgb.org.uk As part of the IARU centenary celebrations, the RSGB has been activating callsign GB0IARU throughout April. On Wednesday, the 30th of April, the RSGB President Bob Beebe, GU4YOX, will be activating GB0IARU from 2 pm on 40m SSB, and then from 5 pm on 80m SSB.

The Kp index peaked at 5.33 on the 21st of April as the solar wind speed hit just above 600 kilometres per second, and active geomagnetic conditions were observed. This was caused by a massive coronal hole on the Sun's surface, which measures nearly 700,000km in length. At the time of writing, part of it is still Earth-facing, but the Bz or interplanetary magnetic field is facing North, so its negative effects are not being felt. The Kp index was down to 3.67 on the morning of Thursday, the 24th of April, but it wouldn't take much for the Bz to swing southwards and for the Kp index to rise again. Meanwhile, the solar flux index has risen from a recent low of 148 up to 168. This has meant MUFs over a 3,000km path have reached 25 MHz at times, but have usually been slightly lower. If the Kp index can stay low, there is a good chance of higher MUFs being attainable, but we have probably seen the best of 10m propagation until the autumn. Much of the recent DX has been worked on slightly lower frequencies, such as VP2VI British Virgin Islands on 40 and 20m, C5R The Gambia on 20 and 12m, and HD8G Galapagos Islands on 20, 17, and 12m. There is still the chance of DX on 10m, but it may be fleeting. Next week, NOAA predicts that the solar flux index will stay high, perhaps reaching 170 to 175. We may get a slight respite from unsettled geomagnetic conditions from the 26th to the 30th of April, when the Kp index is forecast to be around two to three. However, unsettled geomagnetic conditions are forecast for the beginning of next month, with Kp indices of five or six on the 1st and 2nd of May. And now the VHF and up propagation news from G3YLA and G4BAO Next week, high pressure should dominate, meaning a chance of Tropo for much of the time which will probably favour paths to the east, to Scandinavia or northern Europe.  Rain scatter won't have featured much other than over northwest Britain in recent days, and meteor scatter is reducing back to random activity, which tends to be better in the early hours before dawn. The solar conditions have continued to keep the Kp index up, and there was a fine auroral opening last week on the 16th of April, so for more aurora, it's still worth checking for when Kp values nudge above five. As the end of April moves into May, we can start to give serious thought to the coming Sporadic-E season. Hesitant beginnings often show up on 10m and 6m, and, as usual, the digital modes will be best for any weak events. CW and SSB are just possible in the stronger openings, especially on 10m.  The background rule is that there are usually two preferred activity periods, one in the morning and a second in late afternoon and early evening. However, at the start of the season, there can be a lot of spread in the timings. EME path losses are at their lowest with perigee today, Sunday the 27th, and the Moon declination is positive and rising. Moon windows will lengthen along with peak elevation, and 144MHz sky noise starts the week low but increases to moderate as the week progresses. From late Sunday to early Monday, the Sun and Moon are close. 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?

The UK and Ireland DX CW Contest starts at 1200UTC on Saturday the 26th of April and ends at 1200UTC on Sunday the 27th of April. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. UK and Ireland stations also send their district code. The SP DX RTTY Contest starts at 1200UTC on Saturday the 26th of April and ends at 1200UTC on Sunday the 27th of April. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. SP stations also send their province code.   Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 17th of April 2025 Last week was characterised by increased Kp index numbers and severe geomagnetic storms, peaking at G4. These drove down maximum usable frequencies and disrupted DX contacts, especially on the higher HF bands. The solar wind speed increased from 380 kilometres per second to around 500 kilometres per second on the 15th and an increase in plasma density was noted as well. Subsequently, the Kp index peaked at 7.67 on Wednesday the 16th, causing visible aurora alerts in the UK. This was caused by a pair of CMEs that left the Sun on Sunday the 13th of April. We had a total of 22 M-class solar flares over four days, so a CME event was inevitable. Unsettled geomagnetic conditions are a feature on the declining side of a solar cycle, so we could unfortunately be in for many more. According to Propquest, MUFs over a 3,000km path fell to below 18MHz for long periods on Wednesday the 16th, before climbing to around 21MHz at the end of the day. Meanwhile, the solar flux index fell from a high of 170 on Friday the 11th of April to a low of 148 on Wednesday the 16th of April. Next week, NOAA predicts that the SFI will start the week around 145 but could increase to 165 as the week progresses. Unsettled geomagnetic conditions are forecast for the 22nd to the 24th of April, with a predicted maximum Kp index of four. As always, keep an eye on solarham.com for daily updates, but more importantly, get on the bands, which are a much more effective guide to HF propagation! And now the VHF and up propagation news from G3YLA and G4BAO The current period of unsettled weather looks likely to continue into the coming week. This does not mean rain every day, but periods of rain or showers with some intervening drier spells. These drier interludes are not really dominated by high pressure, just gaps between the wetter periods, so it's unlikely to produce much significant Tropo. In terms of propagation, there may be some rain scatter, although it won't be very reliable. However, the prospects for meteor scatter are more promising with the peak of the Lyrids due on Tuesday the 22nd of April. It is worth checking up on procedures for meteor scatter working if you've not done it before and you may find a new part of the hobby to add to your operating schedule. The prospects for aurora continue to be raised by what seems like an almost daily supply of aurora alerts. Continue to monitor the Kp index for signs of elevated values, where Kp is above five, for radio activity. Early signs such as fluttery signals on the LF and HF bands may suggest it's worth looking on the VHF bands for auroral activity. As we move towards the new season it is good to get into the habit of looking for Sporadic-E. The Propquest website www.propquest.co.uk shows several useful components for analysing the Es prospects. If you look at the position of the jet streams shown on the Es blog tab, these can produce favourable conditions geographically to give a hint of the right direction in which to listen. The opening season typically favours 10m or 6m. EME path losses are now decreasing towards perigee on Sunday the 27th of April. Last Friday, the 18th of April, saw minimum Moon declination, so Moon windows will lengthen along with peak elevation. 144MHz sky noise starts this week very high but decreases to low as the week progresses. And that's all from the propagation team this week.

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.

Perhaps you have a query about recent licence changes? Or maybe you'd like to understand more about membership growth? Whatever the topic, the Society is asking you to get in touch. RSGB Board members will be answering your questions during the RSGB 2025 AGM on Saturday, the 12th of April. You can submit your question in three ways; live via Zoom, send a written question in advance, or during the live chat on the day. If you'd like to ask a question about the formal part of the AGM, you'll need to do this via Zoom or by submitting a written question in advance. Don't miss out on this opportunity to discuss what matters to you. Your participation in the AGM is important, and the Society looks forward to hearing from you. Find out more about how to be involved and the deadlines for submitting questions by going to rsgb.org/agm As part of its modernisation of the exam systems, the RSGB has introduced online forms for reporting possible errors found in exam questions. These forms replace the current procedure of writing to the Exam Department. RSGB Examinations Standards Chair Tony Kent, G8PBH, explained that there are two forms. The first can only be submitted by exam candidates and is to formally challenge questions in actual exams, where the outcome of a challenge may affect a candidate's result. The second form can be submitted by anyone and is for informal queries of published exam questions, for example, in mock exams. A separate form is needed for each question that you challenge. Please check carefully that you are using the correct form, otherwise, it may delay the process. Your query will be considered by the RSGB Examinations and Syllabus Review Group, who will let you know the outcome. For more information and to find the forms, go to rsgb.org/exam-challenges The next webinar in the RSGB's Tonight@8 series will be with Nick Wood, M0NTV, on Monday, the 7th of April. Nick will show you how to use a regular glue stick housing in a rather novel way to form the basis of a variable tuning inductor in a homemade 40m receiver. After a brief description of a Direct Conversion Receiver and a short technical explanation of how it works, Nick will dive into four separate modules. At the end of the webinar, he will string it all together, and you'll be able to see some video footage of how it sounds and what it can do. Visit rsgb.org/webinars  to find out more.

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.

The CQ World Wide WPX SSB Contest starts at 0000UTC on Saturday the 29th of March and ends at 2359UTC on Sunday the 30th of March. Using SSB on the 160 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 20th of March 2025 Last week was pretty unremarkable from an HF perspective. 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.

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. You can learn more about 60 meters by checking out the DX Mentor podcast, episode 24. (https://youtu.be/Mq7YN6euHHM ) Just go to YouTube or your podcast app and search for The DX Mentor. Episode 24 will give you all the details about getting on 60 meters. This section of DX News comes from Bernie, W3UR, editor of the DailyDX, the WeeklyDX, and the How's DX column in QST.

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.

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

USA stations also send their state and Canadian stations send their province.  Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 5th of February 2025 Last week went pretty much as predicted. 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.

January 11, 1965, Amateur Radio Station WN9NSO made its first, shaky 5 wpm CW… attempt… in the 40 meter Novice band. 60 years later, WN9NSO is now K4AAQ, our East Coast Host. Return with us now to those thrilling days of yesteryear, as Gary talks about what ham radio was like for that Novice, 60 years ago. No repeaters. No digital (RTTY was it). No computers. Lots of AM.Gary opened up the Zoom and was joined by Ron K9ID, a friend from the Chicago suburbs and then WN9RPD/WA9RPD, and a newer friend, Jerry KE4TTS. Join us for a trip down memory lane.

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.

Using SSB on the 80 and 40m bands, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 9th of January 2025. 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.

GB2RS News Sunday the 5th of January The news headlines: The GB2RS News service is the subject of tomorrow's Tonight@8 webinar The RSGB 2025 election process has begun Don't forget to report YOTA activity!  The news team and all the staff at RSGB HQ would like to wish our newsreaders, listeners and online readers a very happy New Year. We would like to remind everyone that we always welcome your news, by email, to radcom@rsgb.org.uk and the deadline is 10 am sharp on Thursday mornings. And now, on with the news. The first RSGB Tonight@8 webinar of 2025 will be live tomorrow, Monday the 6th of January. During the presentation, you will get a behind-the-scenes insight into the RSGB's GB2RS News service which is celebrating its 70th anniversary this year. The team of presenters include GB2RS News Manager, Steve Richards, G4HPE and also RadCom Managing Editor Ed O'Neill, M0TZX who will explain how a team of people produces and shares the weekly GB2RS news script. You'll also hear from the Society's Operating Awards Manager Lindsay Pennell, GI3KME who has details about a series of special GB2RS awards for you to chase. Pete Sobye, G0PNM will give you a newsreader's perspective of the weekly broadcast.

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. The RSGB National Radio Centre also hosted the callsign over several evenings and weekends. If you were involved with Youngsters on the Air Month and would like your activity to be included in the RSGB's special RadCom feature, remember that you need to email your photos and a short report to comms@rsgb.org.uk by this Tuesday, the 7th of January.  Do you like making things? Or are you interested in creating software for use in amateur radio? Have you thought about entering the RSGB's Construction Competition? This annual competition is judged online to allow RSGB members from the UK and across the world to participate and demonstrate their creativity. In line with the Society's strategic priority of growth, there will be a new Outreach category this year in which members are encouraged to submit a project that can be reproduced in a school or public environment. The other five categories are beginners, construction excellence, innovation, software and antennas. The winner of each section will receive a cash prize, with a bonus for the overall winner. The deadline for entries is the 1st of March 2025.

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.

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. It will open again at 8.30am on Thursday the 2nd of January 2025. During that time, if you need information about amateur radio, exams or RadCom, you'll find lots of information on the website via rsgb.org  If you are planning to visit the RSGB's National Radio Centre at Bletchley Park over the holidays, please note that it will be closed on Christmas Eve, Christmas Day, Boxing Day and New Year's Day. On New Year's Eve, the NRC will close at 2 pm. The National Radio Centre will also be closed for essential maintenance works on Thursday the 2nd of January 2025. Outside of these times, volunteers look forward to welcoming visitors as usual. Remember that RSGB Members can download a free entry voucher for Bletchley Park from the RSGB website via rsgb.org/bpvoucher On the 6th of December, Ofcom announced an update regarding the timing of phases two and three of its amateur radio licensing framework, including changes to the new intermediate call signs and rules for Special event Stations. These phases were originally planned for December 2024 and March 2025 respectively, but Ofcom now expects to deliver them in the third quarter of 2025.

Now the contest news The UK Six Metre Group Winter Marathon started at 0000UTC on Sunday the 1st of December and ends at 2359UTC on Friday the 31st of January 2025. Using all modes on the 6m band, the exchange is signal report and locator. The ARRL 10m Contest started at 0000UTC on Saturday the 14th of December and ends at 2359UTC today, Sunday the 15th of December. Using CW and phone on the 10m band, the exchange is signal report and serial number. US, Canadian and Mexican stations will also send their State or Province code. On Tuesday, the 17th of December, 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 19th of December, 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. 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.

We had another week of high solar flux and good conditions on HF. Solar activity remained at high levels thanks to an impulsive X2.3 solar flare around active region 3883 at 13:40 UTC on the 6th of November, but the event was not responsible for a coronal mass ejection (CME). The Kp index remained below 4.5 all week, with a solar flux index in the range of 240-260. That was more than enough to keep the ionosphere very active. A recent report on spaceweather.com  suggested that the solar cycle may have peaked in the Sun's southern hemisphere but may still have a way to go in its northern hemisphere. It's usual for there to be two peaks in a solar cycle as the two hemispheres are seldom synchronised. We will have to wait and see, but it could mean another three to six months of high SFI numbers as the northern hemisphere catches up. A solar filament located in the southwest quadrant erupted on the 7th of November. A coronal mass ejection, or CME as it is also known, occurred but appeared to be off the Sun-Earth line, so no major impacts are expected. A sunspot group turning into view from off the southeastern limb has been assigned active region 3889 and is producing M-class solar flares. The probability of further M-class flares stands at 80%. Meanwhile, the risk of an X-class flare currently stands at 35%. A coronal hole is currently Earth-facing and could cause some disruption sometime around Saturday 9th. The solar proton flux has decreased to normal levels, so polar paths should now be unaffected. Next week, NOAA predicts that the SFI could decline into the range of 165-185. Geomagnetic disturbances are forecast for the 11th and 12th, and again on the 15th, with the Kp index predicted to reach four. Meanwhile, we do urge you to get on 10 metres, which is currently experiencing some fine DX openings. This month and next will probably give the best chance of good 10-metre propagation for a while.  And now the VHF and up propagation news from G3YLA and G4BAO Another week has just passed with daily F2-layer propagation on 50MHz providing morning openings to Southeast Asia, and the Americas in the afternoon. Expect more in the coming week.  The current spell of high pressure has had a good run with some excellent Tropo conditions, with the best DX along the side of the high pressure. This weekend will see the high finally giving way as weak Atlantic fronts move in from the west. This will soon be replaced by a new high building in the colder air behind the weekend fronts. It may look like Tropo should come back, but this high may be less productive. The major change of weather pattern comes before mid-week, when it may turn more unsettled as low pressure moves closer to eastern areas from the North Sea. This general move towards more unsettled conditions will continue through the end of the week. In terms of propagation, good Tropo will be replaced by some patchy rain scatter opportunities for the GHz bands from about the middle of next week. Staying with scatter modes, meteor scatter looks promising with the Taurids peaking on Tuesday the 12th and the Leonids due to peak on the following weekend on Sunday the 17th. The solar conditions continue to offer chance occurrences of aurora due to solar flares or CMEs so, as usual, keep a watch on the Kp index going above Kp=4. An occasional reminder of the possibility of out-of-season Es for the digital modes is timely. Recently the critical frequency of the Es layer has reached 7MHz on the Dourbes ionosonde plotted on www.propquest.co.uk  and in theory, this would be good enough for a 6m band path. For EME operators, Moon declination is negative but rising, going positive again on Tuesday the 12th. Path losses are falling as we approach perigee next Thursday the 14th. 144MHz sky noise is moderate to low this coming week. And that's all from the propagation team this week.

GB2RS News Sunday the 13th of October The news headlines: The RSGB 2024 Convention is taking place this weekend Two new volunteer Youth Champions have been appointed by the RSGB Celebrations are underway to mark the first trans-global two-way radio communication The RSGB Convention has been in full swing this weekend. If you haven't been able to attend, the RSGB has provided a packed live stream on each day and those live streams are available for anyone to view. Full of presentations, interviews and videos to inspire you, this is another way to enjoy your Convention, in your way. Either go directly to the RSGB YouTube channel or head over to rsgb.org/livestream to see the programme of presentations and the links to the livestreams. The RSGB is delighted to announce the appointment of two new volunteer Youth Champion roles. Chris Aitken, MM0WIC will be the RSGB's School Youth Champion and Rhys Williams, M0WGY/AJ6XD will be the University Youth Champion. Chris is a Computing Science teacher at Wick High School, Caithness. Since 2023, Chris has been running the Wick High School Radio Club, GM0WHS, providing students with a wide range of experiences in amateur radio. He has four students who have passed their Foundation licence exam and are now taking on leadership roles within the club and assisting the latest cohort in their studies. He is also a member of the RSGB Outreach Team. You can contact Chris via youthchampion.school@rsgb.org.uk  Rhys represented the RSGB at the Youngsters on the Air Camp in Prague this year. He sent back daily reports on his activities which you can still see on the website under the summer camps tab at rsgb.org/yota  He is starting a PhD in Aerospace Engineering at the University of Oxford and is keen to help the RSGB support the growth of amateur radio in universities across the UK. You can contact Rhys via youthchampion.uni@rsgb.org.uk  Ben Lloyd, GW4BML is the Board Liaison for youth activities. He said that he welcomes Chris and Rhys to their new youth volunteer roles and looks forward to working closely with them in the future to attract and grow RSGB youth membership. He explained that the three of them have already had some positive conversations and shared some good ideas, which they will be putting into place over the coming months. This week marks the centenary of the world's very first trans-global two-way radio communication. On the 18th of October 1924 Frank Bell, 4AA, from New Zealand, and Cecil Goyder, 2SZ, from North London, changed how we communicate forever by making contact on amateur bands. To commemorate this historic contact, special callsigns will be active, and awards and QSL cards will be available for those who make contact with these special stations. GB2NZ and ZM100DX have already been active since the start of the month. Starting tomorrow, until the 20th of October, calls reflecting Goyder's callsign, G2SZ, and Bell's, ZL4AA, will be active. This will include activity here in the UK from Mill Hill School in North London which is the original location from which Goyder made his contact. On Friday the 18th of October, radio amateurs will also be recreating and re-enacting the first contact between Goyder and Bell. It is hoped that the QSO will be made on a wavelength close to that used in 1924. To find out more about this unique celebration go to gb2nz.com YOTA Month is just around the corner, and the RSGB is looking for volunteers to host the GB24YOTA callsign throughout the month of December. As in previous years, schools, clubs, guide and scout groups and also individuals are invited to host young radio amateurs whilst they operate with the callsign. Each day during the month has been split into a number of operating slots that you can book. In recent years, this system has allowed many more youngsters to get on the radio throughout the month. You can see the operating calendar by visiting QRZ.com and searching for GB24YOTA. Operators should be below the age of 26. Those who do not hold a Full amateur radio licence should be supervised by an appropriate Full licensee whilst operating. The RSGB is pleased that previous activators have already reached out to book their operating slots but there are still many more up for grabs! To book an operating slot or for more information about YOTA Month, please email Jamie, M0SDV at yota.month@rsgb.org.uk During last month's Hamfest in Newark, the ICQ Podcast team spoke with RSGB President John McCullagh GI4BWM, RSGB Board Chair Stewart Bryant G3YSX and RSGB General Manager Steve Thomas M1ACB. Listen to Episode 440 of the podcast series to hear them discuss some of the many events that the Society is currently involved with. This includes the recent Amateur Radio on the International Space Station contact, which Girlguiding and HRH The Duchess of Edinburgh took part in, as well as the RSGB Convention. The second part of the interview, which features the Chair of the RSGB's Propagation Studies Committee, Steve Nichols, G0KYA will be aired during upcoming Episode 441. Visit icqpodcast.com to listen to episode 440 now. The RSGB has been delighted with the number of responses that it has received in response to its call for Jamboree on the Air participation, which is taking place between the 18th and 20th of October. The Society has compiled a list of Scouting groups that are involved with the annual event and has shared it on its website. The list is available by going to rsgb.org/jota and choosing the ‘JOTA Stations on the Air' link on the right hand side of the page. If you are planning to get involved with JOTA and would like to be added to the list, please get in touch via comms@rsgb.org.uk with a summary of your station name, callsign and any other relevant information.

This last week has been characterised by solar flares, coronal mass ejections, or CMEs for short, and an elevated Kp index. Put together, this has resulted in dire conditions on HF, reminiscent of a solar minimum. A visible aurora was seen from the UK once again after the Kp index hit 7.33 on the 8th of October. Numerous CMEs have hit the Earth and the solar proton flux has risen, resulting in a moderate S2 radiation storm as particles blasted away from the flare site. This means poor trans-polar paths until the solar wind abates and the storm settles. Maximum usable frequencies have been badly affected and struggled to get much past 14MHz over a 3,000km path on the 8th of October. Geomagnetic storms were also forecast for Thursday the 10th and Friday the 11th. That's a shame as, before the CMEs hit, HF had been humming with a lot of DX on the 28MHz band and many five-watt beacons romping in from the USA. Next week, NOAA predicts that the solar flux index may drop back into the 170s, but it's anyone's guess as to how geomagnetic conditions will pan out. We have had three X-class solar flares over the past week and on Wednesday the 9th the probability of another X-class solar flare was estimated at 30% and an M-class event at 75%. So, it may be a case of ‘batten down the hatches' on HF until the storm conditions pass. This is not uncommon at this point in the solar cycle and unsettled conditions are likely to continue as we move along the downward portion towards the solar minimum.  And now the VHF and up propagation news from G3YLA and G4BAO The current spell of unsettled weather is probably going to flip into high-pressure mode a couple of times during the coming week. The first of these will be today, the 13th, and through the first half of next week. However, by Wednesday the next change back to low pressure should be with us, closely followed by another attempt to build high pressure later in the week.  This offers something for everyone with prospects for rain scatter on the GHz bands and the possibility of Tropo. The prospects for meteor scatter are also good with October offering several useful meteor showers. While 50 and 70MHz are the best for the mode, look at 144.360MHz in MSK144 digimode. Or, if it's a shower peak, 144.200MHz, the SSB meteor scatter calling channel, to see what's around. The solar conditions continue to behave like a solar maximum and, with several recent powerful flares and CMEs to stir things up, we should continue to check the bands for signs of aurora.  The recent RSGB CW 80m Autumn Series Contest on Monday the 7th of October was about as auroral as it gets with a strong flutter on signals and a challenging hour and a half for participants – so not just an effect for VHF.  The RSGB 1.3GHz UK Activity Contest coming up next week on Tuesday the 15th may be on the changeover from high pressure to low. Tropo might be limited to eastern areas for paths across the North Sea to northern Europe. For EME operators, Moon declination is still negative but will rise to positive by Tuesday night. Path losses are falling towards a minimum at perigee on Thursday the 17th. So, we have increasing peak Moon elevations and longer Moon windows with the lowest loss for the coming week. 144MHz sky noise is low for the rest of the week. And that's all from the propagation team this week.

GB2RS News Sunday the 6th of October The news headlines: The deadline for advance tickets for the RSGB 2024 Convention is tomorrow, Monday the 7th of October The RSGB is interested in what you did for National Coding Week The RSGB's next Tonight@8 webinar will take place tomorrow, the 7th of October The theme for this year's RSGB Convention is “Your Convention, Your Way” and the Society is providing a range of activities and presentations as well as different ways to get involved. There is still just time to buy your tickets in advance, but hurry as advance sales for attending the Convention or the dinners closes tomorrow, Monday the 7th of October. You will be able to buy a Convention ticket on the door but not at the discounted rate that is available now. At the event, there will be a varied programme of presentations regardless of your amateur radio interests or experience, as well as practical workshops and Morse competency tests. You'll also find a room full of special interest groups to chat to who could inspire you to try something new! If you're unable to travel to the Convention, a small number of presentations will be live-streamed and will be available on the RSGB YouTube channel without the need to pre-register. The RSGB has released two ‘Convention Chat' videos recently and will be releasing two more over the coming week, so find out what others think of the Convention and see who you might bump into in the bar! For full programme details and speaker information and to book in advance, go to the RSGB Convention web pages at rsgb.org/convention Did you take part in National Coding Week this year? The RSGB had nine activities to inspire you to take part, including two new worksheets developed by the Society's Outreach Team. Whether you took part by yourself, at a club night, or with friends and family, the RSGB would love to hear from you. To be included in the RadCom December feature on National Coding Week please send a summary of your activity, along with any photos, to radcom@rsgb.org.uk by the 17th of October. The worksheets will remain on the RSGB website for people to try, so if you would still like to have a go head over to rsgb.org/coding and get involved. The next RSGB Tonight@8 live webinar is tomorrow, Monday the 7th of October. Ian White, GM3SEK will present ‘Aircraft Scatter, the Hitch-Hikers Guide'. Aircraft scatter is about bouncing VHF and UHF radio signals off high-flying aircraft – effectively ‘hitching a ride' with someone else's plane to extend your everyday working range up to 800km. It may sound rather technical, but with some explanations from Ian, aircraft scatter might soon feel very easy. During the talk, Ian will consider how aircraft scatter works, and if it's so useful, why haven't we heard more about it? Join the webinar live at 8 pm on the RSGB YouTube channel or special BATC channel. Find out more about this and other webinars on the RSGB website via rsgb.org/webinars grid.radio is a web application born out of the frustration that Rose, 2E0RXO and many others experienced during spontaneous, often unplanned, Parks on the Air activations. During busy moments, someone would inevitably ask for a Worked All Britain square or another reference that she wasn't prepared for. There wasn't a single, simple resource to quickly gather this information with a fast-loading, modern interface. Many websites would spend more time loading advertisements than displaying the necessary information, delaying communication and increasing the pending pile-up. After several months of facing the same issue and finding herself still unprepared, Rose, a Computer Science graduate, decided to solve the problem with code. She created a fast, free web app that can be installed on the home screen of any phone or tablet or accessed on a desktop computer for pre-activation planning. You can also share links so others can easily find out where you are operating from. Once installed, the app will even work without a data connection. Development is ongoing, with feedback from all amateur radio operators welcomed via the contact details on Rose's QRZ.com page. To learn more about this useful web app visit grid.radio 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.   And now for details of rallies and events The 49th Welsh Radio Rally is taking place today, the 6th, at Llanwern High School, Hartridge Farm Road in Newport.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 3rd of October 2024 In the first week of October, the 10m band began to show what it is capable of. With a solar flux index in the high 200s and calm geomagnetic conditions, DX was plentiful. Nick, VK9DX on Norfolk Island was audible on SSB all morning on Wednesday the 2nd and only wanted to work G stations. This made him popular in the UK, but less so in other countries! Vlad, 5H1WX, on Mafia Island, Tanzania, was another strong signal on the morning of the third. Meanwhile, the 3D2V Rotuma Island DXpedition near Fiji on the 10m band using FT4 was another catch for many people. The Kp index managed to remain low for the first half of the week, but there were warnings that a coronal mass ejection, which was attributed to the X7.1 solar flare on the 1st of October, might upset things later in the week. With a good spread of sunspots, mainly in the Sun's southern hemisphere, there could be more flares over the coming days. Scott Mcintosh, the solar physicist who predicted a busier than average Cycle 25, has now questioned whether we are past solar maximum. The fact that there are now fewer sunspots in the Northern Hemisphere suggests that we may be past the peak, but only time will tell. Meanwhile, NOAA predicts the solar flux index may decline towards the 200 mark next week. The Kp index is predicted to go to 4 this weekend. With four of the ten active sunspot groups now classed as growing, we may expect further solar activity and geomagnetic disturbances over the next seven days. And now the VHF and up propagation news from G3YLA and G4BAO The brief period of high pressure that arrived towards the end of the previous week is currently being nudged away to the east into Europe. The coming week is dominated by very unsettled conditions with a succession of deep lows near or crossing the country and there's even one that contains the remnants of an old hurricane. The result is that next week will provide copious amounts of wet and windy weather, so no Tropo for us, but there may be several areas of heavy rain for a try at rain scatter on the GHz bands. We hope you have all checked out your antennas after last week's reminder since the winds may be quite testing for some areas. The solar conditions have been stirred up recently by several flares so, as usual, keep an autumn watch out for auroras. Lastly, there are plenty of meteor scatter opportunities aside from any random meteor activity. Try investigating one of the many meteor websites to see the full list of options. For EME operators, Moon declination is at its minimum on Wednesday. So, it is a good week for checking out systems before the Sun also gets too low in the sky to make sensible Sun noise measurements over the winter. Path losses are still high but starting to fall. If you're fortunate to have a clear low horizon you'll make some contacts, but with peak Moon elevation only eight degrees on Wednesday, you'll be lucky! 144MHz sky noise in general is high to moderate for the rest of the week. And that's all from the propagation team this week.

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.

Foundations of Amateur Radio The other day I was handed a sheaf of paper. The person handing it to me, an amateur, was insistent that I take custody of this little collection. I asked what it was that they intended for me to do with it and the response was that because I did things with history, I should do this too. Aside from taking on a new project, trying to juggle life and income, their observation was pretty spot on, even though I had never quite seen it in that way. Over the years I've often explained things in the context of the era in which it came into being, the first transatlantic telegraph cable in 1858, the first 20m contact between the UK and Australia, back in 1925, the founding of the IARU, also in 1925. For some years I've been playing with the idea of documenting the journey from Spark Gap to SDR. I started writing down milestones, collecting information about the various protagonists along the way, attempting to capture their life milestones and their radio related accomplishments. One friend went so far as to take photos of the replica spark gap transmitter in Hobart, Tasmania as used by Douglas Mawson between 1911 and 1914 during their Antarctic expedition. Between being entrusted with the written history of 28 Chapter of the Ten-Ten International Net and today I've started a spreadsheet. If you know me at all, you know that I love a good spreadsheet. This one is pretty simple, date, event, event type, protagonist, note and source. So far I've got about 85 rows. I'm using it to capture milestones directly related to our hobby, when the first EchoLink node went live, when RTTY came to be used on-air, the invention of FM, when we got access to the 2m band, when 160m was taken away during World War II, ultimately, all of it. There is already a website that documents some of this but it's USA centric, even though our community is global, and it does not include any sources, so there's no way to verify any of the events, which I think is essential if you're going to capture this in any meaningful way. I want this list I'm creating to include all manner of amateur related things, the first time F-troop went on-air, the first CQWW, perhaps even every CQWW. I have also set-up a form so you can contribute your events and over time grow it into something that captures what it is that we've done over the years. Perhaps it will grow into a section on Wikipedia, perhaps it will become its own thing, it's too early to tell. As I've said many times, if you didn't write it down, it didn't happen. So, this is me, or us, writing it down. Perhaps we'll be able to find a way to make it through the next 100 years. You can find the Amateur History Project under Projects on my home-page at vk6flab.com - I look forward to reading your contributions. So, thank you Christine, VK6ZLZ for pushing that sheaf of paper into my hands. I hope I'm worthy of the history that it represents. I'm Onno Vk6FLAB

GB2RS News Sunday the 1st of September The news headlines: RSGB collaborates on a special contact with the International Space Station The RSGB's Tonight@8 webinar autumn programme starts tomorrow, the 2nd The RSGB is getting ready for National Coding Week We are delighted to announce that the Radio Society of Great Britain and ARISS, in conjunction with Girlguiding Surrey West and Brooklands Museum including the Innovation Academy, have been collaborating on a special event due to take place on Saturday the 5th of October. Girlguiding President, Her Royal Highness The Duchess of Edinburgh will attend a planned contact with the International Space Station as part of a visit to promote the engagement and involvement of girls and young women in science, technology, engineering and maths. Further details of the contact and the event will be announced in late September. The RSGB's autumn Tonight@8 programme starts this Monday, the 2nd of September. Brian Coleman, G4NNS will give an update on the Meteor Beacon Project which is a cooperation between the worlds of amateur radio and astronomy. The first phase of this project was completed in May 2022 when the UK meteor beacon GB3MBA went on the air from the Sherwood Observatory of the Mansfield and Sutton Astronomical Society. It enabled studies of meteor events over the UK using simple equipment and made possible a range of STEM projects featuring radio and astronomy. The second phase of the project, which Brian will describe in the presentation, is to develop a network of receivers streaming their data via a central server for detailed studies of individual meteor events. You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. To find out more go to the RSGB website at rsgb.org/webinars The RSGB is getting ready for National Coding Week which begins on the 16th of September. This national event is in its 11th year and encourages people of all ages to try coding, or programming as it is also called. During the next few days, the RSGB's Outreach Team will release two new coding activities for you to try on your own, with members of your local club, or at a school or other youth group. These are in addition to the seven activities the Society shared last year. This is a great opportunity to see how coding can link with your usual amateur radio activities, or for you to try something new. If you are planning an activity or an event or would like some support, please email the RSGB National Coding Week Coordinator Nigel Thrower, G3YSW via ncw@rsgb.org.uk  You can find the coding activities on the RSGB website at rsgb.org/coding The British Science Association has announced that applications for kick-start grants will open on the 17th of September 2024.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of August 2024 We had a good week for HF propagation, at least until we had a Kp index of 5.67 on Wednesday the 28th. This was caused by the Bz component of the interplanetary magnetic field moving into a south-pointing position. Luckily, it didn't last long and geomagnetic conditions were back to normal by Thursday. The solar flux index remains above 200 with no sign of it dropping. But solar flare activity has not diminished either with 16 M-class flares over the past seven days and more than 60 C-class events. There remains a 55% chance of a further M-class flare and a 10% chance of an X-class event. Tuesday the 27th saw some good activity on the upper HF bands with the 10m band opening up at times. VK has been heard on 28MHz in the mornings, which bodes well for the coming months. The top DX choice this week has been CY9C on Saint Paul Island near Newfoundland. The team is active on all bands until the 5th of September using CW, SSB, FT8, Super Fox and RTTY. VOACAP Online shows that the 20 and 17m bands offer the best chance for a contact and are open from 0900 to 2000 UTC. The 30m band is another strong contender from 2000 to 1000 UTC. Next week, NOAA predicts that the solar flux index will start at around 250 but could end the week at 275. As always, it estimates the Kp index will be at 2 all week, but this will depend upon coronal mass ejections, so keep an eye on solarham.com for daily updates. If a solar flare and associated coronal mass ejections do occur, expect the Kp index to rise after about 48 hours, with a lowering of the maximum useable frequency. And now the VHF and up propagation news from G3YLA and G4BAO The autumn season usually brings thoughts of Tropo since areas of high pressure can often be a feature of this time of year. Most models predict that there will be high pressure moving in to offer Tropo conditions today, the 1st. Thereafter, the models differ, and some bring low pressure over the country for much of the coming week, while others maintain a high-pressure story and the continuation of Tropo. This is potentially useful for the 144MHz UK Activity Contest on Tuesday and Wednesday and, if it lasts, the 144MHz Trophy Contest next weekend along with the Backpackers contest on Sunday the 8th. With the uncertain feel of the forecast at the moment, we may find rain scatter is the main option on the GHz bands. Meteor scatter is again reduced to non-shower random events with just a minor shower, the Aurigids, peaking on the 31st of August. This shower has produced brief unexpected outbursts with a zenithal hourly rate of around 30 to 50 per hour in 1935, 1986, 1994 and 2019. Random meteor flux is at its annual maximum in September with relatively good rates, especially during morning hours. Pre-dawn is the best time to try. The solar conditions continue to provide chance auroras. Keep one eye on the Kp index and lock the frequency of some northern European beacons into your rig's memory. Lastly, it's the nominal end of the 2024 summer Sporadic-E season and the daily blogs on Propquest have finished. However, some years can produce surprise Sporadic-E events during the first week of September. Moon declination starts the weekend still high but falling, going negative again on Thursday the 5th. So, Moon visibility windows will also fall, as will the peak Moon elevation. Moon apogee is also next Thursday so path losses are still increasing. 144MHz sky noise is low until Monday but, shortly after moonrise that day, the Sun and the Moon become close in the sky and continue to be until after moonset on Tuesday. This means sky noise will be very high, especially at VHF, due to wide antenna beamwidths.  And that's all from the propagation team this week.

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

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of August 2024 Well, so much for the experts! NOAA predicted that the solar flux index would fall last week when it increased to a whopping 303 on Thursday the 8th. But this high solar flux number was accompanied by a strong risk of solar flares, so it was not all plain sailing. We have had 15 M-class and two X-class solar flare events over the past three days and the threat remains high. Coronal mass ejection activity on Wednesday resulted in NOAA and the Space Weather Prediction Centre warning of possible moderate G2 geomagnetic storming towards the later part of week ending the 11th of August. This could see the Kp index rise and the maximum usable frequency fall. Hopefully, conditions will improve after the weekend. Last week was a good one for HF propagation with a high solar flux index and low Kp index. The 10m band was open to Brazil in the late afternoon, and this appeared to be F2-layer propagation and not multi-hop Sporadic-E. Meanwhile, the 15m band has perhaps been the DX band of choice with long openings to the Far East, at least on FT8, and North America at the same time. HF conditions should also improve as we move into September, but more on that closer to the time. Attention now shifts to N5J on Jarvis Island, an uninhabited 4.5-kilometre-squared coral island in the South Pacific Ocean, about halfway between Hawaii and the Cook Islands. The DXpedition is active on all bands and their website at Jarvisisland2024.com can provide you with personalised propagation forecasts – let us know if you work them. Using Proppy at soundbytes.asia or VOAcap at voacap.com, shows that 20, 17 and 15m  short-path seem to offer the best chance of working the DXpedition, with morning openings from around 0600 to 1000UTC. There is also a potential long-path opening between 1800 and 2000 UTC, with a possibility of the 10m band at 1900 UTC. Both are near polar paths and may be adversely affected by a high Kp index. CDXC members with good stations have already reported QSOs with N5J on the 17m band using FT8. Next week, NOAA predicts the solar flux index will be in the range of 185 to 240. Geomagnetic conditions will depend on whether we have more solar flares and coronal mass ejections, and the chance of those remains high. An Earth-facing coronal mass ejection could send the Kp index soaring, and that will no doubt lead to reduced maximum useable frequencies and noisy bands. So, fingers crossed for more quiet geomagnetic conditions and low Kp indices! And now the VHF and up propagation news from G3YLA and G4BAO The summer tries to deliver but, overall, the pattern has a rather unsettled flavour to it for the coming week. On the positive side, we see a transient area of high pressure crossing southern Britain over this weekend, ending today the 11th. This could give some Tropo conditions but, after this, the Atlantic westerly flow brings a succession of fronts and showers to most areas. In terms of propagation, this suggests that rain scatter will have the best of it in the week ahead. The Sporadic-E season remains a good fallback and surprised us in East Anglia mid-morning on Tuesday the 6th of August with 144MHz Sporadic-E propagation to YU, HA, 9A and LZ moving around towards Italy as the opening progressed. All were workable with 100W and a white stick antenna on FT8. For the coming week, the jet stream activity will probably start by favouring paths to Scandinavia and the Baltic. Later in the week, a new jet stream will drive southeast into Iberia, opening up chances for paths to EA and CT. The Perseids meteor shower this week will provide welcome new fuel for Sporadic-E and, as a result, like most years, we'll see openings into the first week of September. The meteor scatter highlight is the Perseids meteor shower, which peaks on Monday and Tuesday. So, there are plenty of opportunities to try a new mode or fill in some missing grid squares if you are already involved in meteor scatter. Many websites explain what it's all about, but one to start you off is g7rdx.co.uk  Also, try looking for videos of meteor activity on SDR radios to get an idea of what it all sounds like. The solar conditions lately have been rather disturbed. It would not be surprising if the Kp index was to suggest that aurora could be a possibility if it gets to 5 or higher. Moon declination is negative and reaches minimum on Thursday the 15th, which means there will be short Moon visibility windows and low peak elevation. Path losses will decrease throughout the week and 144MHz sky noise is low over the weekend, but climbing to reach a high peak of over 3200 Kelvin on the 15th.  And that's all from the propagation team this week.

Using CW on the 80, 40 and 20m bands, the exchange is signal report, serial number and transmitter power. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of July 2024 We had another week of reasonably settled geomagnetic conditions and a high solar flux index. The solar flux index was at 214 on Thursday the 11th, while the Kp index has been around 2 to 3 all week. That's generally good news for HF.  However, a small coronal hole is now facing Earth and a solar wind stream flowing from this zone was predicted to reach Earth by the 13th of July. This could result in an elevated Kp index and lower maximum useable frequencies, or MUFs for short. It probably won't last too long, so expect conditions to be back to normal by tomorrow, the 15th. Active region 3738 is dominating the Sun's surface but has only been the source of minor C-class solar flares and will remain a threat for moderate M-class flares. All other regions have been mostly stable. The daytime MUF over a 3,000km path has often exceeded 24.9MHz, with some better-equipped stations reporting contacts into Australasia on the 10m band. Night-time MUFs over a similar distance are still consistently above 14MHz. Make the most of this as they are likely to drop as we head out of summer and into autumnal conditions. The MUF is extrapolated from the Dourbes ionosonde data and should only be used as a guide – it may often be higher, especially in some directions. The most sought-after DX this week has been K8K/K8R in American Samoa. The DXpedition is testing out all systems on all bands, using CW, SSB and FT8, ahead of the upcoming Jarvis Island DXpedition. The station has been worked from the UK on the 30 to 10m bands, mainly by well-equipped stations, and has been testing the FT8 Superfox mode with some success. Otherwise, contestants in the RSGB's 80m SSB Club Championship on Wednesday the 10th reported fair conditions, but a very, very noisy band. Noise is often a limiting factor, especially on the lower HF bands. Next week, NOAA predicts that the solar flux index may decline to the 180 to 190 range. Geomagnetic conditions may be unsettled today, the 14th, with a Kp index of 4 at times. The second half of the coming week should be more settled, as long as we don't have a coronal mass ejection. And now the VHF and up propagation news from G3YLA and G4BAO The overall picture is of unsettled weather still being around for the coming week, but there will be some temporary moments of weak high pressure to alleviate incessant rain. As we end the current week, pressure will rise over western areas bringing a chance of Tropo for paths down the Irish Sea and across Biscay. There will also be a second period of high pressure for a time in the middle of next week, favouring the south. This gives us at least a chance of Tropo for this week's UK Activity Contests on the 23cm and 4m bands. The ‘unsettled' part of the story is worth noting, especially if we get some heavy thundery downpours, which should be great for rain scatter. Continuing with scatter modes, there is always meteor scatter as a diversion and the advice is to look in the early hours before daybreak when random meteors are more likely. Solar conditions are still not entirely settled so there remains a chance of aurora should the Kp index rise to 5 or more. The Sporadic-E season is still doing good business within Europe, but it feels as though it's not been quite so noticeable as during June for UK stations. The jet stream pattern is trying to help next week with several useful segments over northwest Europe, which should improve the chances of Sporadic-E paths from the UK into the continent. Moon declination went negative again on Friday the 12th, which also corresponds to apogee, the point at which the Moon is furthest from Earth. So, Moon peak elevation and path losses will continue to fall again next week. 144MHz sky noise starts low early next week rising to a high of 2100 Kelvin on Friday. And that's all from the propagation team this week.

Such is the challenge of writing propagation predictions. Nevertheless, after the X1.5-class flare on the 10th of June, things settled again and, at the moment, there are no incoming coronal mass ejections, or CMEs for short, to report. With a Kp index of less than 1 on Thursday the 13th, and a solar flux index of 165, it looks like HF conditions could be quite good. However, the Sun's proton flux has increased and is close to the 10 million electron volts warning threshold. This means that paths through the polar regions might be disrupted. Protons can herald the arrival of a CME two or three days later, although NOAA is not predicting any disruption. On the 13th of June, the critical frequency was between 7 and 8MHz, meaning a maximum useable frequency over a 3,000km path of around 21 to 24MHz. The 10m band will be open, mainly to Sporadic-E. However, F2-layer propagation on the 10m band will be sparse. NOAA predicts the solar flux index will fall to around 155 today, the 16th, before climbing again to around 195 in a week. Geomagnetic conditions are predicted to be quiet all week, but that may be because solar flares and CMEs are hard to predict at this point in the solar cycle. As always, make hay on the HF bands while the Sun shines! And make the most of the Sporadic-E propagation on the higher HF bands as June is probably a peak month for this. Finally, the latest sunspot data show that the average sunspot number for May was 171.7, the highest in 22 years. However, the ARRL reports that shortwave conditions were above average on only six days out of the entire month of May, and mostly poor on half of the days due to geomagnetic disturbances and solar flares. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of seemingly endless, poor weather is struggling to provide much Tropo. The general theme is low pressure bringing weather fronts with rain or, if not that, then scattered heavy showers. This again points to rain scatter for the GHz Bands as the mode worth exploring. There is just one glimmer of Tropo hope in that the latest model predictions are starting to inject the notion of a ridge developing over southern areas, initially around mid-week but perhaps more so at the end of the week. Although, it's fair to say that other models hang on to the low-pressure theme. That said, it's worth checking from the middle of next week onwards. There are no significant meteor showers this week so continue to check for random meteors around dawn. The solar conditions have continued to trickle charge the auroral oval with an occasionally enhanced Kp index indicating possible aurora. This is unlikely to be visible at this time of the year although, if you are outside with a clear view to the north, you might be rewarded with a seasonal look at noctilucent clouds to make up for it. High-summer Sporadic-E propagation is providing daily contacts so it's worth checking the bands each day. The daily blogs always have something to show on the 10m band and many days there are reports of contacts on the 6m band. Remember these openings are not always reachable from all parts of the UK. One of the characteristics of Sporadic-E is that at each end of the path the ‘signal footprint' is very small. Even in a busy opening, signals may still pass you by but you should continue to monitor in case a Sporadic-E path opens up that does include your station at one end! Moon declination is negative again from this weekend, ending today the 16th. EME path loss was at its highest at apogee on Friday the 14th. 144MHz sky noise starts the week low but rises steadily, reaching over 3,000 Kelvin on Friday the 21st. And that's all from the propagation team this week.  

GB2RS News Sunday the 2nd of June 2024  The news headlines: Nominations for IARU President and Vice President have been ratified The next RSGB Tonight@8 webinar is coming up RSGB National Radio Centre to operate D-Day anniversary special event stations   IARU member societies have ratified the nomination of Tim Ellam, VE6SH/G4HUA and Thomas Wrede, DF2OO as IARU President and Vice President, respectively, for a five-year term which began on the 9th of May 2024. On starting his 4th term as President, Tim Ellam thanked member societies for their support, congratulated Thomas Wrede on his election as Vice President, and also offered a special and heartfelt thank you to Ole Garpestad, LA2RR who retired as IARU Vice President. You can read more on this story via the IARU website at tinyurl.com/IARU2024 The RSGB Tonight@8 webinar this Monday, the 3rd of June, examines how amateur radio can be accessible and enjoyable even if you have sight, hearing or mobility difficulties. Three radio amateurs will explain how they have adapted their equipment, written software or used extra support from the RSGB or other radio amateurs, to enable them to enjoy all that amateur radio has to offer. There will also be input from Sight Matters, an Isle of Man charity helping to assist over 700 visually impaired members. The charity has recently discovered how much amateur radio can offer people with visual impairments and it has formed the Sight Matters Amateur Radio Club. This aims to encourage new people into the hobby and to help assist existing licence holders back onto the air. Whether this webinar is relevant to you, a friend or colleague, or you're in a club that is wondering how to support all radio amateurs to enjoy the hobby, make a note of the date and be inspired! You can watch and ask questions live on the RSGB special BATC channel or YouTube channel at youtube.com/theRSGB The RSGB's National Radio Centre will be operating a special event callsign GB2DAY to commemorate the 80th anniversary of the D-Day landings during World War Two. The station will be active between the 6th  and 9th of June. In addition, volunteers will be hosting the special demonstration station GB1SOE on Saturday the 15th of June. Don't forget that RSGB members can gain free entry to Bletchley Park and the RSGB's National Radio Centre by downloading a voucher from the RSGB website: rsgb.org/bpvoucher The RSGB Board recently spent an afternoon visiting RSGB Headquarters, meeting staff and gaining a more detailed understanding of the work of this professional team. Later that day, the Board received training from members of the senior team about their specialist areas. During the Board meeting the following day, the Board decided to continue with its chosen four strategic priorities until the 2025 AGM. These priorities are the growth of amateur radio; membership of the RSGB; spectrum and licensing; and ensuring the continued financial stability of the Society. To make further progress with the outcomes of the recent growth workshop, the Board allocated a member of its team to champion each of the seven workstreams. Each workstream champion will now create a volunteer team, prioritise work tasks, set measurable objectives, define what success looks like, list deliverables and establish reporting mechanisms and frequency. More details will be shared about these over the coming months. Do you have some spare time to support fellow radio amateurs? Are you passionate about the future of amateur radio? Do you like a challenge? The RSGB currently has volunteer vacancies for Regional Representatives in Region 7 South Wales, and Region 12 England East and East Anglia. Could you fill one of those roles?

But is that all about to change? Active region 3664 has returned. It is now named 3697 and has already emitted an X1.4-class solar flare. You may recall that it was AR 3664 that caused the aurora that was visible all over the UK around the 10th and 11th of May. As Solarham.com says, “The chances for an Earth-directed eruption will increase with each passing day as the active sunspot region turns into a better geoeffective position.” Scientists now believe that the coronal mass ejection associated with the long-duration X1.4-class flare on Wednesday the 29th may pass close enough to Earth to generate moderate G2 geomagnetic storming beginning on the 31st of May – just in time for this weekend's National Field Day! Otherwise, HF propagation has generally been good with decent F2-layer openings up to 21 and even 24MHz at times. The 17 and 15m bands look to provide the best DX, with paths to the east in the morning, and to the west during late afternoon and early evening. The 10m band is subject to Sporadic-E openings, with F2-layer openings mainly restricted to paths to South Africa and South America. Next week, NOAA predicts that the solar flux index will be in the 165 to 200 range, with quiet geomagnetic conditions. However, that is perhaps a little optimistic as active region 3697, or perhaps 3691, could easily throw a spanner in the works, with a flare and associated CME potentially sending the Kp index skywards. So, as always, keep an eye on the current state of the Sun at solarham.com, and work the bands while they are open! And now the VHF and up propagation news from G3YLA and G4BAO The close of the current week offers a temporary return of high pressure for this weekend. This should be good for some Tropo conditions for western parts of the UK. The weather turns a bit more unsettled going through the coming week, especially over northern Britain, but also occasionally in the south. Rain at this time of the year can often be heavy and thundery with good prospects for GHz bands rain scatter, but this may have to wait for the end of next week when a low moves north from France towards the southern UK. The early part of June is a time of several minor meteor showers. These should offer scope for meteor scatter operators as well as provide some fuel for Sporadic-E propagation which rocket measurements show consists of long-lived meteor ions. Sporadic-E propagation is often associated with the position of jet streams in the upper troposphere due to the turbulence that these fast-flowing currents of air generate. In the coming week, the jet stream pattern becomes much weaker, although still with a few options. Daily blogs are available at Propquest.co.uk  for those who are interested. Don't ignore the prospects for multi-hop transatlantic paths to the United States and particularly the Caribbean, which are usually well supported in the early part of the season before the upper winds over the Caribbean change over to high-summer slacker flow.  Equally, multi-hop Sporadic-E paths to the Far East are worth checking in the early morning following the effects of the now displaced northerly meandering jet stream flow across northern Russia. Moon declination went positive again on Saturday the 1st of June, so the coming week will see lengthening Moon windows. EME path loss is falling, reaching a minimum at perigee today, Sunday the 2nd of June. 144MHz sky noise is low apart from Thursday when the Sun and Moon are close in the sky. And that's all from the propagation team this week.

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 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 As you might know I'm in the process of building a cross-platform, open source, contest logger. Right now that project is at the stage where there is a proof of concept that you can use and install as a progressive web app on any web browser. It's intended as a starting point for discussion. Note that this is a long way from the stage where you might want to actually use it for any contest, it's not feature complete and if it breaks you get to keep both parts. It's currently cunningly named "contest-logger". No doubt that will change. I'm collecting suggestions for features using the GitHub issue tracker, which you're welcome to contribute to. Behind the scenes, I'm writing the documentation that describes how I want to actually develop and design this application. What kinds of things are important, what will drive the process, all the planning stuff that sets up the project. Of course I'm doing this whilst writing articles, looking for work and dealing with the health-care fun and games associated with being alive. While my project is nowhere near finished, truth be told, it really needs to start first, I've come across a different tool written by a fellow amateur Michael K6GTE. This tool is written for Linux only in Python and is in Beta release at this point. This means that you can install and run the application and most of the functionality works. The application is called Not1MM. Here's what Michael has to say about his efforts: Not1MM's interface is a blatant ripoff of N1MM. It's NOT N1MM and any problem you have with this software should in no way reflect on their software. If you use Windows you should run away from this and use some other program. I personally don't. While it may be possible to get N1MM working under Wine, I haven't checked, I'd rather not have to jump through the hoops. Currently this exists for my own personal amusement. Something to do in my free time. While I'm not watching TV, Right vs Left political 'News' programs, mind numbing 'Reality' TV etc... Michael goes on to say that: The current state is "BETA". I've used it for a few contests, and was able to work contacts and submit a cabrillo at the end. I'm not a "Contester". So I'll add contests as/if I work them. I'm only one guy, so if you see a bug let me know. I don't do much of any Data or RTTY operating. This is why you don't see RTTY in the list of working contests. The Lord helps those who burn people at the... I mean who help themselves. Feel free to fill in that hole with a pull request. You can find Not1MM on Michael's GitHub repository ready for your testing and experimentation. It's also available as a PyPi package if you're already familiar with Python. In my opinion, one thing that this tool does well is consider how contest logging can be customised for individual contests and likely it will serve as inspiration for how I intend to implement the plugins in my own project. I've also submitted a patch to Not1MM so you can use Docker to install it on your own machine or at least see what the requirements are to make it run in your environment. I'm thrilled to have discovered this tool and hope that it solves some of your contest logging issues on your Linux workstation. What features are you hanging out for in your contest logging adventures? Feel free to share your bug reports and feature requests to either Michael's project, or mine, or both. I'm Onno VK6FLAB

Foundations of Amateur Radio We describe the relationship between the power of a wanted signal and unwanted noise as the signal to noise ratio or SNR. It's often expressed in decibels or dB which makes it possible to represent really big and really small numbers side-by-side, rather than using lots of leading and trailing zeros. For example one million is the same as 60 on a dB scale and one millionth, or 0.000001 is -60. One of the potentially more perplexing ideas in communication is the notion of a negative signal to noise ratio. Before I dig in how that works and how we can still communicate, I should point out that in general for communication to happen, there needs to be a way to distinguish unwanted noise from a desired signal and how that is achieved is where the magic happens. Let's look at a negative SNR, let's say -20 dB. What that means is that the ratio between the wanted signal and the unwanted noise is equivalent to 0.01, said differently, the signal is 100 times weaker than the noise. In other words, all that a negative SNR means is that the ratio between signal and noise is a fraction, as-in, more than zero, but less than one. It's simpler to say the SNR is -30 dB than saying the noise is 1000 times stronger than the signal. Numbers like this are not unusual. The Weak Signal Propagation Reporter or WSPR is often described as being able to work with an SNR of -29 dB, which indicates that the signal is about 800 times weaker than the noise. To see how this works behind the scenes, let's start with the idea of bandwidth. On a typical SSB amateur radio, voice takes up about 3000 Hz. For better readability, most radios filter out the lower and upper audio frequencies. For example, my Yaesu FT857d has a frequency response of 400 Hz to 2600 Hz for SSB, effectively keeping 2200 Hz of usable signal. Another way to say this is that the bandwidth of my voice is about 2200 Hz, when I'm using single side band. That bandwidth is how much of the radio spectrum is used to transmit a signal. For comparison, a typical RTTY or radio teletype signal has a bandwidth of about 270 Hz. A typical Morse Code signal is about 100 Hz and a WSPR signal is about 6 Hz. Before I continue, I should point out that the standard for measuring in amateur radio is 2500 Hz. This is significant because when you're comparing wide and narrow signals to each other you'll end up with some interesting results like negative signal to noise ratios. This happens because you can filter out the unwanted noise before you even start to decode the signal. That means that the signal stays the same, but the average noise reduces in comparison to the 2500 Hz standard. This adds up quickly. For a Morse Code signal, it means that turning on your 100 Hz filter, will feel like improving the signal to noise ratio by 14 dB, that's a 25 fold increase in your desired signal. Similarly, filtering the WSPR signal before you start decoding will give you roughly a 26 dB improvement before you even start. But there's more, since I started off with claiming that WSPR can operate with an SNR of -29 dB. I'll note that -29 dB is only one of the many figures quoted. I have described testing the WSPR decoder on my system and it finally failed at about -34 dB. Even with a 26 dB gain from filtering we're still deep into negative territory, so our signal is still much weaker than the noise. There are several phenomena that affect the decoding of a signal. To give you a sense, consider using a limited vocabulary, like say the phonetic alphabet, or a Morse character, the higher the chance of figuring out which letter you meant. This is why it's important that everyone uses the same alphabet and why there's a standard for it. To send a message, WSPR uses an alphabet of four characters, that is, four different tones or symbols. Another is how long you send a symbol. A Morse dit sent at 6 words per minute or WPM lasts two tenths of a second, but sent at 25 WPM lasts less than 5 hundredth of a second This is why WSPR uses two minutes, actually 110.6 seconds, to send 162 bits of data, lasting just under one and a half seconds each. If that's not enough, there's a processing gain. One of the fun things about signal processing is that when you combine two noise signals, they don't reinforce each other, but when you combine two actual signals, they do. Said in another way, signal adds coherently and noise adds incoherently. To explain that, imagine that you have an unknown signal and you pretended that it said VK6FLAB. If you combined the unknown signal with your first guess of VK6FLAB and you were right, the unknown signal would be reinforced by your guess. If it was wrong, it wouldn't. If your vocabulary is small, like say four symbols, you could try each in turn to see what was reinforced and what wasn't. There's plenty more, things like adding error correction so you can detect any potentially incorrect words. Think of it as a human understanding Bravo when the person at the other end said Baker. If you knew when to expect a signal, it would make it easier to decode, which is why a WSPR signal starts at one second into each even minute and each symbol contains information about when that signal was sent, which is why it's so important to set your computer clock accurately. Another is to shuffle the bits in your message in such a way that specific types of noise don't obscure your entire message. For example, if you had two symbols side-by-side that when combined represented the power level of your message, a brief burst of noise could obliterate the power level, but if they were stored in different parts of your message, you'd have a better chance of decoding the power level. I've only scratched the surface of this, but behind every seemingly simple WSPR message lies a whole host of signal processing magic that underlies much of the software defined radio world. These same techniques and plenty more are used in Wi-Fi communications, in your mobile phone, across fibre-optic links and the high speed serial cable connected to your computer. Who said that Amateur Radio stopped at the antenna connected to your radio? I'm Onno VK6FLAB

Foundations of Amateur Radio Yesterday I finally discovered the missing piece of information that will allow me to create a project that I've, if not outright spoken about, at least hinted at. In an ideal world by now I'd have built a proof concept and would be telling you that I've published a GitHub repository under my callsign for you to explore. If wishing made it so. Unfortunately, currently sitting at a keyboard for anything longer than ten minutes or so makes it nigh on impossible to stand up, so you'll have to make do with hand waving and gesticulation rather than actual code, but for now, that's all I have. Consider this a design specification if you're so inclined. So, big idea. Imagine that you have a device that can listen to radio frequencies. This device is connected to a network and it shares the data to any number of different listeners which might each do something different with the information. If you were to do this in the way we watch YouTube or listen to streaming audio, each listener would get their own unique copy of the data. If you have ten listeners, you'd have ten streams crossing your network, even if everyone was enjoying the exact same video or audio at the exact same time. Instead I want the data coming from the device to have only one stream on the network and for as many different listeners or clients to access it as required at the same time. Let's get specific here for a moment. I'm talking about using a software defined radio, could be a $25 RTL dongle, could be any SDR, that is tuned to a part of the spectrum, let's say the entire 40m band, and sends that radio information digitally onto the network. This network could be your local network, or it could theoretically be the internet, for now, let's just put it out on our own network. So, you have a copy of the entire 40m band streaming across your network. Great, now what? Well imagine that you want to decode RTTY on 7.040. You fire up your decoder, point it at the network stream and decode RTTY. Then you want to decode a WSPR signal, at 7.0386. You fire up your WSPR decoder, point it at the network stream and decode WSPR. Then you want to decode FT8 on 7.056, same deal, fire up your decoder, point it at the network stream and decode FT8. Now you want to compare two different RTTY decoders. Fire them both up, point them both at the same stream, decode both, simultaneously. Of course you could do this with CW signals, with SSB signals, with any decoder you have lying around, Olivia, Hellschreiber, AM, Packet, whatever. All these decoders could be running independently but together on the same band. You could add a tool that shows a waterfall display of the same data on a web page, or play some of the decoded data to your headphones, or record it to disk, or do spectral analysis, all at the same time. The information that you're processing is on the network once. You don't have to flood your network with multiple copies of the 40m band, the only limit is how much CPU power you can throw at this and to be frank, most computers on the globe today spend much of their time waiting for you to do something, so processing a bit of data like this is not going to tax anything built in the past 20 years or so. The missing ingredient for this was a Linux tool called netcat, or nc. It allows us to distribute the information across the network using a technique called broadcasting. So, RTL dongle, data extracted by a tool called rtl_sdr, distributed across the network using netcat and used by as many clients as you can think of. The proof of concept I'm working on uses Docker to build a bunch of different containers, or clients if you like, that each can do a different task with the same stream. When I've got something to show and tell, you'll find it, predictably, on my GitHub page. Oh, if you want to run the same thing for say the 80m band, you can. Now you have two network streams, one for 40m, one for 80m and as many decoders on your network as you have CPU cycles to play with. If all this sounds like magic, you've seen nothing yet.
