Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 15th of May 2025 This week, you could be forgiven for thinking that the Solar Cycle 25 maximum is now over. With a reduced solar flux index and an almost blank Sun, there was little to get excited about. By Thursday, the 15th of May, the SFI was 122, but previously, on the 12th, it had been down to 116, which is the lowest it has been for some time. There is still a lot of solar activity going on, but most of it is not conducive to good HF propagation. Over the past week, we have had two X-class solar flares and five M-class events. The X-class events were associated with coronal mass ejections, but these appear to have been directed away from Earth. A fast solar wind has resulted in the Kp index standing at four for a lot of the time, namely on the 9th and 10th of May and again on the 14th and 15th. Unfortunately, this is not uncommon at this point in the solar cycle and adds some evidence that we are now in the declining phase of Cycle 25. Next week, NOAA predicts that things may improve with the SFI set to rise from the 19th of May. It forecasts the SFI will start the week around 115, but then will climb steadily, reaching 145 by the 1st of June. After a brief rise on the 19th with a Kp of four, things then become more settled with a Kp of two between the 22nd and the 28th of May. A large elongated coronal hole became Earth-facing on 16th May, which could cause raised K indices and lower MUFs from today, the 18th of May, onwards. It looks like the best HF F2-layer conditions may occur between the 22nd and 28th of May. And don't forget, despite the HF doldrums, we are now well into Sporadic-E season with short-skip occurring, predominantly on 10m. But more of that shortly. And now the VHF and up propagation news from G3YLA and G4BAO The prolonged spell of high pressure is likely to remain until near the end of this week, so there is plenty of time to get some more Tropo in the log. Cloudier and cooler air over eastern Britain at the end of last week may enhance the Tropo by adding moisture under the inversion. For most places, the strongest Tropo conditions will be overnight and early morning, then they will degrade as the daytime heating destroys the surface temperature inversion. Meteor scatter is declining a little, apart from a few stragglers from early May showers, so it's probably better to keep to the early morning period as your go-to time for meteor scatter to focus on any random input. Rain scatter is unlikely until next weekend, but it might be worth thinking about the GHz bands from this Friday, the 23rd of May, onwards. Aurora is a different matter, and the solar activity is likely to keep things interesting as a large sunspot group rotates into an Earth-facing position. Strong Es opened on Wednesday, the 14th of May, so it's definitely the season to be checking the upper HF and lower VHF bands for Sporadic-E. In this recent opening, the Dourbes ionosonde peaked at an Es critical frequency of 14 MHz, which is a very high value, even for mid-season. There were strong signals from the central Mediterranean on 6m CW, and some may have even got some 2m digital mode action from the brief opening. Check the Propquest NVIS tab for the day to see the details of this event. Although weak jet streams were present, the opening may well have been helped by some very intense, slow-moving thunderstorms over France. Remember to start checking on 10m and, if it's open, look to the higher bands of 6m, 4m, up to 2m. EME path losses are still falling. Moon declination ended last week at minimum but goes positive again this Thursday, the 22nd of May. Moon windows and peak elevation are again rising. 144MHz sky noise is high this weekend, falling back to low as the week progresses. And that's all from the propagation team this week.

GB2RS News Sunday the 29th of September   The news headlines: There is still time to book tickets for the RSGB 2024 Convention The RSGB is helping to promote JOTA activities in October The RSGB has responded to a recent Ofcom Consultation concerning the 2.3GHz band   With just two weeks until the RSGB Convention, this year's event is the place to go if you are interested in anything and everything to do with amateur radio. There will be a host of expert speakers presenting on topics ranging from Sporadic-E and how to use AI to write amateur radio applications, to panel debates on amateur radio modes and presentations on inspiring the next generation of radio amateurs. The presentation summaries and speaker biographies are now available on the RSGB speaker page. AMSAT-UK has started to release news of its presentations too and you can see those on the RSGB's Convention programme. There really is something for everyone. If you haven't already bought your ticket, be sure to secure it by Monday the 7th of October when the online booking process will close. Buying tickets before the event will save you up to £5 off the usual 'on the day' ticket prices. Due to demand, the RSGB has also arranged an extra introduction to microcontroller programming workshop that will take place on the Sunday morning. There are still some tickets available for Saturday's Gala Dinner too. To book your tickets for any part of the weekend or to find out more about the programme go to rsgb.org/convention Jamboree on the Air, also known as JOTA, is taking place between the 18th and 20th of October. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the groups within the Scout Association. Some groups have already shared details of activities that will be taking place over the weekend and the RSGB plans to compile and share a list of these on its comms channels. If you are part of a Scouting group and are planning to get involved with JOTA then please get in touch via comms@rsgb.org.uk with a summary of your station name, callsign and any other relevant information. The RSGB has responded to a recent Ofcom Consultation which would see new users sharing spectrum within the 2.3GHz amateur band. Whilst the new devices may be limited to indoor use, the RSGB has taken the opportunity to highlight concerns regarding the weak signal 2320MHz segment. In addition, the RSGB has also indicated its wish to review the current restrictions that apply to this band that date back to 2013, when it was subject to Public Sector Spectrum Release. The response and background information can be found in the Spectrum Forum web pages at rsgb.org/spectrum-forum The October edition of RadCom includes an article about the very first two-way radio communication between the UK and New Zealand, something that Sir Edward Appleton, radio physicist and Nobel laureate, later described as “probably the most dramatic moment in the history of the development of the short waves.” The contact was between two radio amateurs, one in Mill Hill School, London and the other on a sheep farm in New Zealand. Centenary celebrations will be taking place in New Zealand and at Mill Hill School, and special event callsigns will be active from today until late October. GB2NZ and ZM100DX will be active each day during that period and, for the week of the centenary, the near-actual callsigns used in 1924, G2SZ and ZL4AA, will be active from the 14th to the 20th of October. A commemorative certificate will be available for those who make contacts with the event stations. For more information on the Goyder-Bell award, and to find out more about the centenary celebrations, go to gb2nz.com Lots of amateur radio stations are on the air this weekend for the Railways on the Air event. The occasion marks the anniversary of the first steam-powered passenger railway journey which took place on the 27th of September 1825. The first passenger train ran on a line in the North East of England from Darlington to Stockton. Activity will be centred around 3.65, 7.15 and 14.25MHz.

Newly assigned AR 3835 in the southeast quadrant is the main source and the event looks to have thrown a stream of plasma into space. The latest model suggested a possible passage near our planet by the 25th and it looks like the prediction was correct. The Space Weather Prediction Centre issued a G1 geomagnetic storm watch and visible aurora may be likely at very high latitudes. Expect maximum useable frequencies, or MUFs for short, to decline if the Kp index is above 4 or 5. Other than a large number of C-class solar flares in the past five days, this was the biggest eruptive event to occur. The solar flux index had declined to 172 on Wednesday the 25th but is unlikely to decrease much further. Note that nearly all the sunspots are in the Sun's southern hemisphere at the moment. Meanwhile, daytime MUFs over a 3,000km path are now consistently over 28MHz under quiet geomagnetic conditions. This is good news for fans of the 10m band. Night time MUFs over 3,000km are around 14 to 16MHz, so it looks like we may soon lose the 24-hour DX openings on the 20m band, which are prevalent in the summer months. Increasing solar proton flux at the moment means paths over the Arctic Circle may be compromised. Daytime critical frequencies remain over 8MHz and often reach nearly 11MHz, so NVIS communications around the UK on the 40m band remain commonplace but may disappear later in the evening. NOAA predicts that the solar flux index will increase next week but may not reach the 200s. Keep an eye on solarham.com  for daily updates.   And now the VHF and up propagation news from G3YLA and G4BAO The present run of unsettled weather has become firmly established and, although many parts of the country have not seen the torrential rain and flooding of last week, there will be some rain at times in most parts of the country during the first week of October. There are a couple of brief periods in the models when a weak ridge of high pressure is due to cross southern areas, but these are not seen as great for Tropo. The week beginning Monday the 30th of September sees at least two major lows pass close to northern Britain. One occurs as this weekend draws to a close and there may be another one later in the week. These types of changeable patterns are notorious for problems with detailed predictions beyond a few days, although the general weather type is well forecast. Just a reminder that strong wind events at the end of a long summer can be a big shock to antennas, so now is a very good time to check that all is well in the guying department. Having discounted Tropo as an option, the obvious choice will be rain scatter on the GHz bands, but some of these events may produce very fast-moving echo sources. So, it could be quite a challenge although last week saw plenty of good rain scatter conditions. Meteor scatter is again largely dependent upon random meteors with just a couple of lesser showers, the Kappa Leonids and Sextantids, which see out the end of September. The auroral situation continues to provide some excitement, and the autumn months are a good time of the year for such things. For EME operators, Moon declination is still positive until Tuesday evening, so Moon visibility windows are shortening. Path losses are high with apogee next Wednesday the 2nd of October. Thursday the 3rd sees near-eclipse conditions when the Sun and Moon are close in the sky meaning high noise with wider beam width antennas. 144MHz sky noise is, in general, low for the rest of the week. And that's all from the propagation team this week

GB2RS News Sunday the 15th of September The news headlines: The RSGB is looking for its next Youth Champion Success for an RSGB member at the IARU ARDF Championship Today is the last chance to book early bird tickets for the RSGB Convention The RSGB is looking for its next volunteer Youth Champion.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of September 2024 Last week showed that HF conditions are improving as we head into the autumn. With a solar flux index still above 200, there was plenty of DX available to work. CDXC members reported working VP6WR on the Pitcairn Islands, KH8T on American Samoa and 3D2USU on Fiji, which is not a bad catch for early September. A little closer to home, 9A168TESLA in Croatia has been popping up for short periods celebrating the 168th anniversary of the birthday of electrical pioneer Nikola Tesla. Watch DX Summit closely for operating times. The daylight maximum useable frequency, or MUF, over 3,000 kilometres remains above 28MHz on the whole, although a raised Kp index tends to reduce this. Geomagnetic conditions remained relatively calm with the Kp index below 3 all week. That changed on Thursday the 12th as material from a coronal mass ejection, or CME passed the ACE spacecraft in the early hours. The solar wind speed increased to more than 500 kilometres per second and the Bz swung south. On Thursday the 12th, the Kp index was 5 and the Met Office Space Weather department was forecasting potentially unsettled conditions for this weekend, ending today the 15th. At the same time an X-class flare occurred, with lowered MUFs due to increased D-layer absorption. Two large coronal holes on the Sun's surface are also now Earth-facing and threaten to add to the solar wind this weekend. According to NOAA's predictions, the solar flux index should stay in the 210 to 225 range next week, although a large number of spots are about to rotate off the Sun's visible disk. This may be compensated by an active region that's about to rotate into view. This has been emitting C-Class and lower-level M-flares and could potentially be the same region that produced several energetic eruptions off the far side of the Sun over the past week. Time will tell. And now the VHF and up propagation news from G3YLA and G4BAO The heavy showers at the end of last week produced some good rain scatter, but no QSOs in the UK were noted due to the showers not coinciding with GHz contests and few suitable home stations were active to take advantage of them. After a gradual build-up of pressure over this weekend, ending the 15th, high pressure is suggested by most models during the coming week. However, there is some uncertainty about the position of the high.   Currently, models are favouring the north of Britain and this means that in the south, although still on the edge of high pressure, there could be a brisk northeasterly breeze, which may weaken the inversion prospects. It's not clear if the Tropo will be functioning in time for the 70MHz Affiliated Societies Contest today, the 15th, but should be helpful for the 1.3GHz UK Activity Contest on Tuesday the 17th and the 70MHz UK Activity Contest on Thursday the 19th. Solar conditions are still likely to offer the chance of the occasional elevated Kp index, which is a good sign of possible aurora. It will be interesting to see how things evolve this weekend, ending the 15th, as a series of expected CMEs are due to reach Earth.  The amateur bands between 10m and 2m are the ones to check as well as looking out for ‘watery' sounding signals on the HF bands. Remember it doesn't have to be dark for radio aurora, so don't wait for dusk before checking. Meteor scatter is mainly down to random activity in the coming week. However, with the September Epsilon Perseids stream still active until the 21st, having peaked on the 9th, conditions may be slightly enhanced. For EME operators, Moon declination is negative but rising and going positive again on Wednesday the 18th. Moon visibility windows will continue to rise while path losses decrease as we approach perigee on Wednesday the 18th. 144MHz sky noise is moderate for the whole of next 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 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.

On Sunday the 26th, the UK Microwave Group High Band Contest runs from 0600 to 1800UTC. Using All modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 16th of May 2024 After last weekend's auroral spectacular, it was nice to see the Sun calm down a little and the bands get back to normal. But that didn't last long. To recap, on Friday the 10th of May the Kp index shot up to 9, due to the effects of a number of coronal mass ejections, while the HF bands closed down in the subsequent geomagnetic storm. While there was visible aurora across the UK and Europe, HF propagation suffered and didn't start to recover until the late afternoon on Saturday the 11th. The main culprit, active region 3664, has now rotated out of view, but that doesn't mean we are out of the woods just yet. Solar flares can cause short-term disruption to HF propagation due to their X-rays penetrating deep into the D-region and causing signals to be absorbed. Subsequent coronal mass ejections can cause longer-term degradation of the F2 layer with reduced maximum usable frequencies, noisy bands and auroral conditions.  At the time of writing, the Kp index stood at 6 again so it looks like unsettled geomagnetic conditions are continuing with a moderate G2 geomagnetic storm in progress. Low to moderate activity is now expected, with a slight chance of further strong-class flares. The regions currently on the visible disc are smaller and simpler, with isolated M-flares possible from these. However, a new active region, now rotating into view, has already emitted an X-class solar flare. Next week, the United States Air Force predicts that the solar flux index may remain in the 160 to 180 range. HF conditions remain a lottery as they can be badly affected by solar flares and coronal mass ejections. It is best to keep an eye on solarham.com for updates, and also propquest.co.uk for near real-time reports of the critical and maximum usable frequencies. And now the VHF and up propagation news from G3YLA and G4BAO The weather remains on the unsettled side of things with areas of rain and some thunderstorms over the country, especially the south as we end this week. As this report is being read out, high pressure is becoming established over northern and western Britain. This may eventually take a tenuous hold over the rest of the country during the second half of the coming week and into next weekend, the 25th and 26th. This high pressure, although fairly weak, may help with some Tropo for those in northern Britain in the 144MHz May Contest and the Backpackers Contest this weekend, ending on the 19th. It may also be helpful to those taking part in the 1.3GHz UK Activity Contest on the 21st. However, the conditions may not be of much use in the south as another low arrives from the continent. Overall, rain scatter on the GHz bands will probably be worth exploring in the rainy areas again, since some of the showers may be heavy and thundery. The prospects for Aurora are still worth keeping in mind despite the recent stunning event. Minor non-visible events can still provide a reasonable radio aurora to explore. The Sporadic-E season continues to develop. And with such unsettled weather, there are plentiful jet streams to act as source regions for turbulence, which can propagate up to the E region where they can generate Sporadic-E. We are currently at the tail end of the Eta Aquariids meteor shower. A few meteors from this shower will continue to appear, but no major shower is expected this week. The lowest Moon declination occurs this coming Friday. With the Moon being full on the 23rd, a clear sky should reveal an impressive ‘Flower Moon'. For EME, path loss will still be relatively high, although the Moon is starting to move back towards its closest point to Earth, or perigee. 144MHz sky noise starts the week low but rises to high on Saturday the 25th. And that's all from the propagation team this week.

Using CW and SSB on the 80m band, the exchange is signal report, serial number and county code. On Thursday the 21st, the 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 14th of March 2024 What a difference a month makes. We've gone from a solar flux index up to almost 200, to one that is down in the 120s. Over the past week, we have had only two M-class solar flares, which means we have had limited coronal mass ejection activity and therefore low Kp indices. Last weekend's Commonwealth Contest saw UK amateurs making plenty of HF contacts, some with Australia, but everyone agreed that HF propagation was a little lacklustre. There is a daily chance of moderate-class solar flares from AR 3607, the largest sunspot region, but all remaining spots remain mostly small and simple. The solar wind speed has been quite high with sporadic periods of a south-pointing Bz field. This is what has pushed the Kp index to three, but this isn't a big threat to HF. There is a slight chance of unsettled intervals caused by a weak coronal hole near the south centre of the solar disc coupled with the fast solar wind. NOAA reports that active region 3590 has been detected on the far side of the Sun using helioseismology. This may mean that it will still be active and a threat when it returns in a week or so. This region was the source of the X6 solar flare on the 22nd of February – the largest so far in solar cycle 25. Next week, commencing the 18th of March, NOAA predicts that the solar flux index will remain in the 120 to 130 range, although the US Air Force predicts it could reach 150. Geomagnetic conditions are likely to be mainly settled with a maximum Kp index of two or three.  So, this is a reasonable forecast for HF propagation, which should remain open up to 28MHz during daylight hours. This is also a good time for north-south paths, such as the UK to South Africa, and the UK to South America. And now the VHF and up propagation news from G3YLA and G4BAO The continuing theme of unsettled weather will produce further spells of rain and heavy showers and once again provide some rain scatter options on the GHz bands. Another thing to mention is that, as we move towards the latter part of the month, the intensity of showers becomes greater due to the additional warmth improving the effectiveness of the rain scatter process. It is very hard to find any traditional Tropo until we get well into the coming week. It may occur on Thursday the 21st when a high will develop a ridge from Biscay across southern Britain and the near continent. This should provide a chance of Tropo for the final few days of the coming week. Unfortunately, this is not in time for the UK Activity Contest on 1.3GHz on Tuesday the 19th, but the 70MHz UK Activity Contest on Thursday the 21st may be luckier. The north of Britain may start to see the next low bringing rain over that weekend, so although it has an early exit from any Tropo, at least being well north gives Scottish stations a head start for any aurora, which tends to favour the spring months. Meteor scatter remains in the random territory – try just before sunrise for best results. But with the next major shower being the Lyrids in late April, we have a while to wait for an uptick in activity. Lastly, a brief mention of Sporadic-E. It has popped up with some weak events on the Dourbes plots on Propquest, but the main season is still a little way off. Maybe check next month for a heads-up on the lower bands like 28 and 50MHz. Of course, digital modes will get a head start, so best to check the clusters and chatrooms for signs of fleeting activity. Some UK stations reported 50MHz trans-equatorial propagation to Africa last week, so check for that. For EME operators, Moon declination reaches a maximum on Sunday, but path losses are starting to increase again. 144MHz sky noise is moderate, falling to low on Wednesday. And that's all from the propagation team this week.

GB2RS News Sunday the 15th of October 2023 The news headlines: • RSGB Construction Competition • New chair of the RSGB's Exams and Syllabus Group • RSGB 2023 Convention The RSGB recognises the importance of construction as a key element of amateur radio, whether that is using traditional construction skills or is a software or systems engineering project. The Society has launched its 2024 Construction Competition and the deadline for entries is the 1st of March 2024. To enable members across the country, and even the world, to enter, entries will be judged over the internet rather than in person. This year a new category called ‘Antennas' has been introduced so there are five categories you can enter: Beginners; Construction Excellence; Innovation; Software and Systems; and Antennas. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded for the winner of each section, with a bonus for the overall winner, who will also be declared the winner of the Pat Hawker G3VA Award. You can find out more, including how to enter, on the RSGB website at rsgb.org/construction-competition The RSGB is delighted to welcome Andrew Lenton, G8UUG as the new Chair of the Exams and Syllabus Review Group. The Society would also like to thank Donard de Cogan, M0KRK for his hard work and dedication, including chairing the Group for the past three years. You can contact Andrew via esrg.chair@rsgb.org.uk The RSGB 2023 Convention takes place over both days this weekend. There is a fantastic range of presentations on a variety of amateur radio topics. If you haven't already booked, you can buy day tickets on the door or join the Livestream at any time over the weekend. The Livestream contains 12 of the Convention presentations as well as exclusive interviews and additional content. We are asking radio amateurs to register for the Convention Livestream this year. Whether you are there in person, or joining radio amateurs from across the world online, make sure you are part of this major annual event. For more information about the full programme of presentations go to rsgb.org/convention and to register for the Livestream head over to rsgb.org/livestream As we get closer to the ITU World Radio Conference, WRC-23, which starts next month, the future of amateur radio, particularly the 23cm band, is of key importance. The ITU News Magazine has a feature article by IARU President Tim Ellam, VE6SH regarding amateur activity in the 23cm band. This is the topic of a challenging agenda item at the Conference which calls for measures that protect primary radio-navigation services such as Glonass and Galileo from amateur terrestrial and satellite usage. You can read the article by visiting tinyurl.com/TimVE6SH In related news, the IARU also reports that the last formal preparatory meeting ahead of the WRC on this topic was difficult and could not achieve a consensus on measures such as power and bandwidth limits, or frequency restrictions. The IARU supports further efforts and will continue to try to find a solution regarding suitable recommendations, whilst opposing the unwarranted statutory imposition of such. You can read the IARU's post on this subject via tinyurl.com/ITUR23cm  Also, you can hear the latest updates at the RSGB Convention on Sunday, in a talk by IARU expert and RSGB Microwave Manager Barry Lewis, G4SJH.  Jamboree On The Air, or JOTA, is an annual event in which Scouts and Guides all over the world communicate with each other via amateur radio.

The Worked All Germany Contest starts at 1500UTC on Saturday the 21st of October and ends at 1500UTC on Sunday the 22nd of October. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. German stations also send their DOK reference. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of October 2023 We had a period of low geomagnetic disturbance last week, which allowed the upper HF bands to shine. There were lots of reports of DX being worked on the 10m band as the Kp Index sat mainly in the ones and twos, with a maximum of Kp 3.33 for one three-hour period on the 9th. The Solar Flux Index, or SFI, also remained in the 150s and 160s, hitting a maximum of 166 on the 9th. All in all, these were very good conditions for high-band DXing, especially at this optimum time in the calendar. As promised last week, let's take a look at HF paths from the UK to the W8S Swains Island DXpedition in the South Pacific. The good news is that operations are in full swing and are being spotted daily on the DX Cluster. At a distance of approximately 9,500 miles from the UK on the short-path, and 15,300 miles on the long-path, it's quite a distance for signals to traverse. The short-path beam heading you need to select is a polar path at 350 degrees, and for long-path 169 degrees. The best openings to Swains from the UK start on the 20m band from about 0630UTC. As the morning progresses, move up in frequency until you get to the 10m band around 1000 to 1100UTC. This path should remain open until 1500 or 1600UTC, at which point you can drop down to the 12, 15 or 17m bands. Long-path openings may be a lot weaker, with a short opening on the 15m band from 0600 to 0800UTC. Then move to the 12 or 10m bands from 0700 to 0900UTC. There may also be a long-path evening opening from 1800 to 2000UTC on the 17 and 10m bands. The above predictions are for SSB and CW. You may find FT8 openings extend these times a little. For more details, and to compute your own predictions, see VOACAP.com or Proppy at soundbytes.asia/proppy This weekend, ending today the 15th, may see some geomagnetic disturbances due in part to a coronal hole. But, as long as we don't get any coronal mass ejections, this should settle after the weekend.  The Solar Flux Index is predicted to remain in the 150s with a maximum Kp index of two. If this turns out to be true, we should have a good week of DX hunting to come. And now the VHF and up propagation news The coming period of weather offers many changes, and it looks as though we have said goodbye to the warm air, with low pressure controlling events.   Just a gentle reminder to keep an eye on your antennas as this time of year can produce surprisingly rapid developments of deep low-pressure systems with associated strong winds.  Early next week, a temporary high returns to give you a chance to give those antenna supports and guys a once-over while winds are light, and leave the potential Tropo until the evenings and overnight. Incidentally, this new high is essentially a cold air high, so may not be as productive as the recent Tropo of the week just ending. The new high will probably hang around until midweek when it should migrate north to allow an easterly wind across the south. This will probably bring some showery rain along the east coast. It's possible that we may have some rain scatter from these showers. Meteor scatter is always good in October, with high random meteor rates and a number of small showers. Most notable of these is the Orionids Meteor Shower which peaks on the 22nd of October and is active until the 7th of November with an average zenithal hourly rate of around 20. Of course, aurora is also worth keeping in mind if you get any spare time! For EME operators, Moon declination is negative and falling all week, reaching minimum on Friday the 20th with corresponding shortening Moon windows. As we are now past apogee, path losses will continue to fall.  144MHz sky noise starts very high with the annular eclipse on Saturday the 14th. The following week sees it moderate, increasing to a high of over 2000 Kelvin on Thursday. And that's all from the propagation team this week.

The Raspberry Pi 5 is the latest version of one of the world's most popular computers. It was just announced on Thursday and will be released on October 23rd. The new model comes in two versions, a 4GB and an 8GB model, priced at $60 and $80 respectively. Compared to the previous Raspberry Pi 4 models, these prices are only $5 more.Raspberry Pi 5 is faster and improvedOne of the main improvements of the Raspberry Pi 5 is its faster processing power. It features a new Broadcom system on a chip (SOC) with a quad-core CPU running at 2.4GHz and a quad-core GPU. The previous model had a CPU running at 1.8GHz and a GPU with lower clock speed. The new SOC allows for overclocking up to 3GHz, providing even better performance.The GPU of the Raspberry Pi 5 is a video core seven GPU with a stock speed of 800MHz, compared to 500MHz on the previous model. Although overclocking the GPU did not result in significant graphics improvements, the overall performance of the device is noticeably faster for various tasks.Another notable improvement is the inclusion of the RP1 chip, designed by Raspberry Pi, which controls the IO for the USB3 ports, USB2 ports, and Ethernet port. This allows for higher throughput, resulting in faster read and write speeds for USB devices. The Ethernet port remains a gigabit port, providing similar speeds to the previous model. The Wi-Fi card, however, has a faster interconnect to the CPU, resulting in double or more than double the speed of the Raspberry Pi 4 under good conditions.The Raspberry Pi 5 does not come with a fan, but it is recommended to use one to prevent overheating. Without a fan, the device can reach temperatures up to 80 degrees Celsius, which is the throttle point. The official fan, specifically designed for this layout, is available for around $6. It can be easily mounted on the device using the dedicated mounting holes and four-pin header.Overall, the Raspberry Pi 5 offers significant improvements in processing power, graphics performance, and IO throughput compared to its predecessor. It is a highly anticipated computing device that provides faster and improved capabilities for various applications.New Raspberry Pi features power buttonOne of the standout features of the new Raspberry Pi 5 is the addition of a power button, which is a first for the Raspberry Pi line. This power button allows users to easily turn the device on and off without having to unplug it from the power source. However, it is important to note that the power button is not a hard cutoff switch, but rather a soft momentary button that initiates shutdown when pressed.The addition of a power button may not seem like a significant feature, but it offers several benefits. Firstly, it eliminates the need to unplug the device to turn it off, which can be inconvenient and potentially lead to the corruption of the SD card. With the power button, users can safely shut down the Raspberry Pi without the risk of data loss or corruption.Additionally, the power button allows for easier and quicker boot-up times. When the Raspberry Pi is plugged into the power source, it automatically boots up, eliminating the need to manually turn it on. This can be particularly useful in situations where the device needs to be constantly powered on and off, such as in a server setup.Furthermore, the power button is programmable, meaning that users can customize its functionality to suit their needs. Currently, pressing the power button brings up the shutdown menu on the screen. However, it is possible to program it to perform other actions, such as initiating a specific command or launching a particular application. This programmability adds an extra layer of versatility to the Raspberry Pi 5 and allows users to tailor its functionality to their specific requirements.

You can contact Tim with ideas or feedback for future editions via radcombasics@rsgb.org.uk  RSGB Members can access all issues of RadCom Basics by visiting rsgb.org/radcom-basics RSGB Director Ben Lloyd, GW4BML has taken on the challenge of activating ten summits during 12 days on the remote Scottish islands. He will climb some with his partner and fellow radio amateur Martha, and their two-year-old daughter Lyra. This SOTA – or Summits on the Air – challenge combines Ben's favourite hobbies of amateur radio and hiking, but it also sometimes brings with it adverse weather conditions and the need to reach remote islands by kayak! Ben is hoping that by sharing his challenge he will not only inspire radio amateurs to try SOTA, but he will also encourage people who love walking and hiking to try amateur radio. You can catch up with his adventures on the RSGB social media channels and through the special playlist of videos on the RSGB YouTube channel. Go to youtube.com/theRSGB and choose the playlist called “RSGB Director Ben Lloyd, GW4BML - SOTA challenge”. The next Tonight@8 live webinar is on Monday the 2nd of October when Lee Volante, G0MTN will give a presentation aimed at newcomers to contesting. He will explore how contesting began, explain why it is rewarding and fun, and demonstrate how anyone can take part in their first contests with equipment they have today. Watch on the RSGB YouTube channel and find out more on the RSGB website at rsgb.org/webinars The RSGB QSL Bureau reports that, due to unforeseen circumstances, well-known volunteer Roy Taylor, M0RRV is retiring from his post as volunteer sub-manager for the M1 to M7 groups.

A period of minor G1 geomagnetic storming was observed on Tuesday the 26th thanks to an enhanced solar wind stream containing a long-duration southward-facing Bz component. If the solar wind's Bz magnetic field points south, it more easily couples with the Earth's magnetic field, allowing solar plasma to flood in. The net result was a Kp index of 5.67 and visible aurora seen from the UK once again. It is worth reminding people that, at this point in the solar cycle, conditions are being governed more by the Kp index than the solar flux index. A high Kp index generally results in lower MUFs and poor HF conditions. During the week, the solar flux index was around 175, declining to 156 on Thursday the 28th. The number of solar flares also decreased as the week progressed. Next week NOAA predicts that the solar flux index will remain in the range 145 to 155, perhaps hitting 160 on the 7th. NOAA also predicts quiet geomagnetic conditions with a maximum Kp index of 2. As we said last week, at this point in the cycle solar flares and coronal mass ejections are very prevalent and hard to predict. So, do not be surprised if the Kp index goes up again. Otherwise, if it remains low, make the most of the good HF conditions that generally follow. Finally, as it is now October, we can expect another step up in HF conditions as we enter Autumn, so keep an eye on the 10m band, which should be opening up to the US and Canada in the afternoon. There are plenty of 10m beacons to listen for from 28.160 to 28.330MHz, as well as FM repeaters clustered around 29.600MHz.   And now the VHF and up propagation news Last week saw trans-equatorial openings on 50MHz with V51 Namibia reported all over the UK, as far north as Scotland around 1900UTC. On the tropo front, last week was fairly unsettled with a visit from Agnes, our first named storm of the season, which affected the north and west. The coming week is looking much more suitable for VHF radio with high pressure building over the country from Tuesday, bringing a good chance of Tropo as we go through the week. This may not be fully developed for the 144MHz UK Activity Contest on Tuesday the 3rd, but possibly starting to help lift conditions, in the south at least. The high pressure will become more widespread over the next week, but by the following weekend of the 7th and 8th of October, the 1.3GHz Trophy may have to deal with more disturbed conditions in western areas. However, conditions will still probably be good for eastern areas across the North Sea to southern Scandinavia. The meteor scatter prospects are improving as we move towards the October Draconids, which peak on the night of the 8th and 9th. Auroras have also featured recently so should remain in our checklist. Incidentally, although we are technically outside the main Sporadic-E season, Dourbes ionosonde data plotted on the Propquest website have shown occasional ‘blips' in the critical frequency of the Sporadic-E layer, for example to 7.5MHz around 1650UTC on Wednesday the 27th of September. This would certainly be enough for 10m and perhaps even 6m chance openings. ‘If in doubt call CQ' is the take-away message here. Moon declination goes positive on Friday the 29th of September and reaches its peak the following Thursday. This means increasing Moon elevation and lengthening Moon Windows until then. The downside being that path losses are increasing all week ahead of apogee on the 10th of October. 144MHz sky noise starts off low, increasing to 500 Kelvin next Thursday before dropping again for the weekend. And that's all from the propagation team this week.

GB2RS News Sunday the 17th of September 2023 The news headlines: RSGB Strategic Priorities RSGB 2023 Convention YOTA month The RSGB Board has chosen four strategic priorities for the Society to focus on until the 2024 AGM. These are the growth of amateur radio; membership of the RSGB; spectrum and licensing; and ensuring the continued financial stability of the Society. These priorities will set the framework for the RSGB's activities over the coming months. Both HQ staff and volunteers across the range of RSGB teams will be involved in planning how best to implement these four priorities. Look out for further details in the coming weeks. The RSGB 2023 Convention has a great speaker programme and there are also some fantastic forums to take part in. The RSGB HF and VHF Forums will take place on Sunday, and on Saturday in conjunction with ICQPodcast, the RSGB is offering Convention attendees the chance to discuss two important topics. The first will challenge you to consider and take responsibility for the issues within amateur radio today – for example, is amateur radio just about what you like? Should someone else fix the issues you see? The second forum will focus on QRM and how both newcomers and experienced radio amateurs can sometimes feel frustrated or discouraged by on-air activities. In both forums you can discuss personal experiences, share ideas, and help to promote positive interactions with fellow radio amateurs. You will leave with a notepad full of ideas. The only way to participate in these forums is to be at the Convention, so do book your package or tickets now! Full information about the updated programme, speakers, the drop-in buildathon and the social scene are on the RSGB website at rsgb.org/convention December is Youngsters on the Air, or YOTA, month and is an exciting opportunity for you, your club, school, or social group to host an amateur radio station with the aim of getting youngsters active on the amateur bands. Once approval from Ofcom is received, the RSGB will provide access to the special callsign GB23YOTA and a full list of operating slots will be made available on QRZ.com. These slots will be first-come, first-served, so check your calendars and reserve your place as soon as possible.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of September 2023 While our terrestrial weather this week was variable, it seems our space weather was equally unsettled! We warned last week that it wouldn't take much to cause the Kp index to rise and on Tuesday a coronal mass ejection, or CME, hit the Earth sending the Kp index to 5.67. The Bz component of the interplanetary magnetic field tipped sharply south for a long duration causing visible aurora to be seen across the north of the UK and as far south as Cornwall. This really hit HF quite hard and good signals were scarce. Unsettled radio conditions continued into Wednesday bringing the Maximum Usable Frequency, or MUF, over a 3,000km path down below 18MHz for most of the day. The Kp index was still around 3 or 4 on Thursday, but MUFs were recovering and were at around 28MHz over 3,000km by lunchtime. Next week NOAA predicts that the Solar Flux Index will start the week around 165 and then decline as the week progresses, perhaps ending at around 145 to 150. Geomagnetic conditions are forecast to be quiet, at least until the 23rd when the Kp could rise to four. But at this point in the solar cycle the risk of a solar flare, and subsequent CME, remains high every day, so watch solarham.net for up-to-date information. And finally, a new paper by NASA's Lisa Upton and David Hathaway indicates that sunspot maximum is now forecast to be in the Autumn of 2024. They predict a maximum sunspot number of 135, plus or minus 10, which is slightly larger than Cycle 24's maximum of 116.4, but well below the average of 179 for Solar Cycles 1 to 23. And now the VHF and up propagation news Tropo conditions are still present over southern areas today, the 17th. However, by early next week, low pressure will be a dominant force and the coming week looks very unsettled with rain and quite strong winds at times. This means that any Tropo, either across the southern North Sea or down across Biscay, will not last beyond this weekend, ending today the 17th. The unsettled low-pressure-driven weather will mean that rain scatter is a distinct possibility on some of the more active days. The other propagation modes are the usual fall-backs of meteor scatter using random meteors and aurora, which may not be too far-fetched in view of the geomagnetic activity and visible auroras experienced recently. The September Epsilon Perseids meteor shower has already peaked earlier in the month, but a few lingering meteors may give some truly random radio reflections. Last week there were indications that this normally quiet period after the August Perseids and the forthcoming October Draconids can still provide some interest for persistent meteor scatter enthusiasts. During this coming equinox week, the Moon will reach its lowest declination of the month on the 22nd and 23rd. This point also coincides with the Moon being in Sagittarius, so that sky noise will be very high. This will make moon bounce operations particularly difficult towards the end of the week. And that's all from the propagation team this week.

In his spare time, he will operate CW with 10W. Frans, DJ0TP will be active as TK/DJ0TP from the main island of Corsica, EU-014, until the 3rd of September. QSL via DJ0TP's home call and Logbook of the World. Now the contest news Today, the 13th of August, the Worked All Europe DX CW Contest ends its 24-hour run at 2359UTC. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. On Tuesday the 15th of August, the 1.3GHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on 1.3GHz frequencies, the exchange is signal report, serial number and locator. On Thursday the 17th of August, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. 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 10th of August 2023 Sunspot activity continues as we head towards the solar maximum. Or have we already gone past that point? Identifying solar maximum can only really be done in retrospect. That is after we have already had it! Solar maximum is now forecast for early to mid-2025 so we still have some way to go. Last week the Solar Flux Index declined from 176 on the 5th, to 153 on the 10th. Geomagnetic conditions were mainly settled, other than a Kp index of 6.67 on the 5th. This was due to an incoming plasma cloud from a coronal mass ejection, or CME, that left the Sun on the 2nd of August. We had not one, but two X-class flare events recently. These occurred on the 5th and the 7th. The event on the 5th was long in duration with a peak flux at 2221UTC. Luckily it was from active region 3386, which was right on the edge of the visible solar disk, so any associated CME was directed away from Earth. The second event at 2046UTC on the 7th was also from AR3386, which by now had rotated just out of view of the Earth, so again its associated CME was not Earth-directed. So, we were lucky on both counts. If this sunspot region is still active on its return, we could be in for a rough ride. Keep an eye out from around the 20th of this month when it should reappear. HF conditions have been variable, with occasional F2-layer openings on the 10m band. The 15m band has produced some good DX including 5W1SA in Samoa on FT8. The 17m band produced Roland, TR8CR in Gabon on CW for Laurie, G3UML. S79KW in Seychelles was worked by Hugh, EI2HI on 10m SSB, but it has otherwise been quite quiet. Expect more HF DX activity later next month. Next week, NOAA predicts that the Solar Flux Index will be in the low 160s, with a maximum Kp index of two. If that does pan out, we can expect fairly good HF conditions. But as always, watch out for solar flares and CMEs that can't be predicted terribly well. A solar flare could result in a sudden ionospheric disturbance but that would be relatively short-lived. A CME, which might follow a flare in about two days, could see the MUF drop for a day or more. And now the VHF and up propagation news The brief period of high pressure around the middle of last week will be long gone by the weekend and new Atlantic lows will again dominate the UK weather. At first, this will be mainly over the northern half of Britain before moving to the western side of the country later in the week. This means that any Tropo at the end of the previous week is not here to stay. The low-pressure input will bring rain scatter propagation modes and, since we are supposedly in the summertime, the rainfall events may be quite heavy or even thundery in places, so there may be good scattering for the GHz bands. The Sporadic-E season is still simmering with a few brief moments of single hop within Europe, but also some longer multi-hop paths including to the Far East and VK on 10m. The upper air pattern of jet streams may still be able to trigger a few openings during the coming week, although it is looking much weaker than last week and possibly mainly biased towards northern areas like the Baltic and Scandinavia. Meteor scatter is one mode that should do well, especially at first with the peak of the Perseids this weekend. It can be quite interesting to monitor the 2m meteor scatter calling channel and stand outside watching for meteors, especially if it's a bit warmer! The shower has a broad peak so should still provide activity during the coming week. Lastly, the Sun continues to offer occasional disturbed conditions with a chance of high Kp indices and possible aurora. The easiest solution is to monitor the Kp index and perhaps your favourite Scottish beacon for signs of auroral flutter. With the Moon at maximum declination this weekend, with long Moon visibility windows, it's the Microwave EME contest. Moon apogee is next Wednesday so path losses are at their highest until then. 144MHz sky noise is moderate until late Tuesday when the Sun and the Moon are close in the sky until Thursday when levels drop back to low.    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 TX power. On Monday the 17th of July, the RSGB FT4 Contest runs from 1900 to 2030UTC. Using FT4 on the 80, 40 and 20m bands, the exchange is your report. On Tuesday the 18th of July, the 1.3GHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on 1.3GHz frequencies, the exchange is signal report, serial number and locator. On Thursday the 20th of July, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of July 2023 Last week saw the arrival of one of the biggest sunspots of this cycle. Active region 3363 could swallow the Earth four times over. It is a source of M-class flares, but at the time of writing hasn't produced any X-class events. A new sunspot region 3372 has just rotated into view and has also been the source of eight M-class flares, one of which may have caused a coronal mass ejection that could give a glancing blow to the Earth this weekend – watch this one for more activity as it rotates into an Earth-facing position. Meanwhile, the Solar Flux Index has been hovering around the 200 mark, meaning daytime MUFs over a 3,000km path are around 21MHz, sometimes slightly lower. At night this falls to around 14 to 18MHz so don't write off HF once the sun sets. Next week, NOAA's Space Weather Prediction Centre has the Solar Flux Index around 175. While we have been lucky that Earth has not been subjected to too much geomagnetic disruption, after any disturbance across the weekend, the Space Weather Prediction Centre has forecast that the Kp index will be around two again all week. So it may be ideal for DX, like Silvano 9Q1AA/9Q1ZZ in the Democratic Republic of the Congo, who has been active on the 10 and 15m bands recently. Or the KH8RRC DXpedition to American Samoa which is active until the 18th. Remember, there is DX to be worked – you've just got to pick the right band and time. And now the VHF and up propagation news The predominant theme this week is driven by low pressure systems, meaning further days of heavy rain or thundery showers and a distinct lack of Tropo from areas of high pressure. However, there is a split in the different models' view for southern Britain later in the coming week in which some try to build a ridge across southern UK and France from the Azores high. Check the forecast charts from Wednesday onwards to see which version ‘wins'. In the meantime, the heavy rain will continue the recent good run of rainscatter on the GHz bands. Sporadic-E will probably continue to be a feature on most days somewhere in Europe. Last Wednesday night saw another good opening to Newfoundland. Remember that there are plenty of online clusters and map plots showing where the focus of activity is located. Each day a blog is published on propquest.co.uk detailing the locations of likely Sporadic-E activity, based upon the positions of various weather features suspected of being responsible for the location of Sporadic-E patches. The recent behaviour of the Sun has regularly affected the prospects for VHF propagation by interaction with the Earth's magnetic field giving a high Kp index, above five, which can be a sign of auroral conditions. A high Kp index is potentially a bad thing for Sporadic-E prospects, some operators suggesting that it is possible that solar flare activity may also be a negative influence on Sporadic-E. Meteor scatter prospects continue to improve due to two broad-peaked showers coming up later in the month. This weekend sees maximum Moon declination but losses are high as we approach apogee next Thursday. 144MHz sky noise is moderate until Monday when the Sun is close to the Moon for the whole day's pass, lasting until 9am on Tuesday. After this, sky noise is low for the rest of the week.   And that's all from the propagation team this week

Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and ITU zone. The UK is in zone 27.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of June 2023 The solar flux index stayed in the 150s and 160s last week, which is good news for HF propagation. From a flare and CME perspective, we have been lucky in that we have only had a few solar flares, all of which have been C- or M-class. As a result, the Kp index has remained fairly low, being in the range of one to three after the rise to a Kp of five on the 25th due to the solar wind's magnetic field, or Bz, tipping south. We are, however, still in the summer doldrums, so daytime DX is limited thanks to D-layer absorption. We still recommend checking the bands at night as the MUF over 3,000km is still exceeding 14MHz and often reaching 18MHz at times. During the day Sporadic-E may still keep you entertained on the higher HF bands.   Daytime critical frequencies are around 5.2 to 6.7MHz according to the Dourbes ionosonde, which means you may find close-in contacts tricky on the 40m band at times, whereas more DX distances are still fine. Near vertical incidence skywave or NVIS, 40m signals may not be returned to Earth with that critical frequency. Looking ahead, active sunspot region 3354 was pointing directly at the Earth on Thursday but has so far been behaving itself with mostly C-class flare events. It is still the most likely candidate for a coronal mass ejection, or CME, over the weekend. Next week the Space Weather Prediction Centre has the Solar Flux Index declining to 130 before picking up later in the week to perhaps 145. The Kp index should remain around two unless we have a CME which could see it rising to five with the attendant lowering of the MUF. Meanwhile, you can get an idea of the best times to work various parts of the world by using the free Proppy software at soundbytes.asia/proppy or via VOACAP.com   And now the VHF and up propagation news The next week or so looks likely to continue in a very unsettled theme with low pressure residing over Scandinavia for much of the time and producing a west or north-westerly pattern over the UK. This will mean that tropo propagation will not be a large part of our operations during the period ahead. On the other hand, the frequent spells of fronts with prolonged rain or heavy summer showers will make rain-scatter modes a good use of time on the GHz bands. Talking of scatter modes, we are not in a major meteor shower at present, so random meteors are a good fail-safe although it can entail spending a lot of time in the process. The solar conditions, as previously mentioned, can be unsettled at the moment, and thus there is a potential for radio aurora if the Kp index goes above seven or so, even though daylight makes visible events unlikely at this time of the year. Lastly, the Sporadic-E situation is still our primary focus as we move into July. Days with good jet stream activity over Europe are good signs, whereas a high Kp index or solar flares are generally not so good. Of course, there are many other parameters involved and one of the critical components is likely to be the random meteor count which shows how much meteor debris might be available to make the Sporadic-E patches. In a roundabout way, if you monitor the meteor pings you might get a feel for how the Sporadic-E prospects are stacking up. The Moon declination is negative all week so there will be short Moon windows. Tuesday's perigee means that path losses are at their lowest for the month. 144MHz sky noise is high this weekend but falling back to low levels by the end of the week. And that's all from the propagation team this week.

GB2RS News Sunday the 25th of June 2023 The news headlines: Ofcom consultation on updating the amateur radio licensing framework RSGB Tonight@8 webinar ‘Fly Your Satellite!' programme An Ofcom consultation titled “Updating the amateur radio licensing framework” opened on Friday the 23rd of June 2023. According to Ofcom, the proposals set out in the consultation aim to “provide greater operating freedom for radio amateurs; and make the process of getting and using a licence simpler, clearer and more responsive.” The closing date for responses is the 4th of September 2023. All radio amateurs are strongly encouraged to read the consultation via Ofcom's website directly. You can also find the consultation by visiting rsgb.org/licencereview and clicking the Ofcom logo. The RSGB will provide guidance on how to respond to the consultation via the same web page in due course.  The next RSGB live Tonight@8 webinar will take place at 8pm on Monday the 3rd of July, with Eric P. Nichols, KL7AJ presenting “Receiving antennas are different”. Eric, who has written numerous amateur radio and electronics articles over the past 30 years, says that almost every ham radio station can benefit from a separate receiving antenna. Effective receiving antennas are optimised for best signal-to-noise ratio, not necessarily the greatest gain. Tune in to the RSGB YouTube channel or special BATC channel to hear Eric discuss the countless interesting means of building high signal-to-noise ratio receiving antennas. You can find out more at rsgb.org/webinars The ‘Fly Your Satellite!' programme, initiated by the European Space Agency, presents an exciting challenge for radio amateurs and space enthusiasts worldwide to establish communication via the LEDSAT CubeSat digipeater. This unique opportunity invites participants to connect with the ESA Education Office ESTEC Ground Station in the Netherlands through the satellite digipeater, with a chance to win a special prize – a custom QSL card issued by the ESA Education Office and the LEDSAT team. Running from the 26th of June to the 30th of July, this challenge offers an exciting chance for radio enthusiasts to engage with space technology and demonstrate their communication skills. For more information go to the European Space Agency website at esa.int and search for “Connect and communicate with a satellite via the LEDSAT Digipeater Challenge.” It was with profound shock and sadness that the RSGB learnt of the untimely loss, at the age of 49, of Mr Alexandre ‘Sasha' Kholod, Chairman of the CEPT WRC-23 Conference Preparatory Group. Alex was head of international frequency planning for the Swiss regulator and was widely respected and influential in CEPT and ITU. Of note to amateurs is that he chaired CEPT Project Team C which led to the successful ITU Region 1 50MHz allocation for the amateur service at World Radio Conference 19 in November 2019. His warm and professional personality will be sadly missed.   And now for details of rallies and events The Newbury Radio Rally is taking place today, Sunday the 25th of June.

The Solar Flux Index reached 180 on the 20th of June with a massive spread of sunspots across both solar hemispheres. But an X-class solar flare erupted on the same day. This was only just X-class though, as at X1.1 it barely hit the requirements. Luckily, its associated coronal mass ejection was directed away from Earth. We passed the summer solstice this week so are now heading towards Autumn. Don't worry too much, though, as there is plenty of summer left, complete with its lower daytime maximum usable frequencies and high levels of D-layer absorption. Fortunately, multi-hop Sporadic-E is also bringing occasional DX on the higher bands. As we pointed out last week, nighttime MUFs remain high, partly due to seasonal norms and partly due to the high solar flux. There were reports this week of 15m CW still being open at 3.30 am local time, when Paul, MM0ZBH worked the VP6A DXpedition on Ducie Island. There have also been many reports of VP6A being worked on the 80m band at around 0800 UTC. Next week the Space Weather Prediction Centre puts the Solar Flux Index at around 165 to 180 again. We can expect unsettled geomagnetic conditions once again around the 27th and 28th of this month. Daytime F-layer MUFs over a 3,000km path are generally around 21MHz, but there are occasional surprises. Sporadic-E still dominates on the 10m band. At night, MUFs over 3,000km are often around 14 to 18MHz, again with some surprises at times. And now the VHF and up propagation news After a slow change to a more summer-like pattern of showers and sunshine with occasional fronts in the last week, it does seem like it's a continuation for the coming week. This means further opportunity for rain scatter on the GHz bands and with a reasonable chance of tracking the storms with any of the online weather radars. There will be a tendency for higher pressure close to southern Britain with possible Tropo, which will extend south across Biscay to northern Spain or farther south towards the Canaries and perhaps beyond. It may even offer paths east across the southern North Sea towards Denmark. There have been some reasonable Sporadic-E paths within Europe and beyond to the Americas. Paths have also opened eastwards to the Far East or Middle East and there is no reason not to expect similar for the coming week. As next week progresses, the jet stream distribution may favour paths to Scandinavia and the Baltic, plus across the Atlantic to the States. The recent unsettled solar conditions may affect the prospects for Sporadic-E propagation if the Kp index becomes too high, but on the plus side it could then be worth checking for aurora. Don't forget that random meteors can provide a few chance QSOs using meteor scatter propagation and there have been audible meteor ‘pings' on some Sporadic-E QSOs recently, so they do exist! Moon declination goes negative again on Monday – so shortening Moon windows. Path losses will fall all week, and 144MHz sky noise is low to moderate until next weekend when it reaches more than 2500 Kelvin on Sunday. And that's all from the propagation team this week.

GB2RS News Sunday the 18th of June 2023 The news headlines: His late Majesty, King Hussein of Jordan's UK amateur radio equipment Coding and amateur radio RSGB Convention 2022 presentations   The Radio Society of Great Britain is delighted to announce that Her Majesty Queen Noor of Jordan has chosen to donate the UK amateur radio equipment of His late Majesty, King Hussein of Jordan to the Society. His Majesty was a great ambassador for amateur radio and, whenever his official duties allowed him, his radio callsign JY1 could be heard on the amateur bands. His Majesty always operated modestly, never announcing himself as King Hussein, always just ‘Hussein from Jordan'. A permanent display is being organised at the RSGB National Radio Centre so that the equipment can be used to help inspire people to get involved in amateur radio and promote communication, friendship and understanding throughout the many countries and cultures of the world. The RSGB extends its thanks to Her Majesty for this generous donation. National Coding Week has been run for many years in the third week of September. Coding is used increasingly in amateur radio, and the BBC Micro:bit and the Arduino have made it easier for radio amateurs of all ages to discover more about this. As part of its commitment to encourage youngsters into amateur radio and to support lifelong learning, the RSGB will be providing resources and creating coding activities for people to get involved in throughout the month of September. The Society is keen to hear from volunteers who have ideas for this initiative and would like to be part of it. Further details will follow but, if you're interested, in the first instance please contact Exam and Syllabus Review Group member John Hislop, G7OHO via g7oho@rsgb.org.uk The RSGB has released two further Convention 2022 presentations. In the first, Noel Matthews, G8GTZ provides an introduction to the challenges of operating on 122GHz and gives an overview of the VK3CV-designed transverter boards which have put operation within the reach of amateurs without requiring advanced electronic and mechanical engineering skills. He tells the story of how he and Dave, G1EHF used the boards to work up from their first QSO over 2km to breaking the UK record for 122GHz at 36.5kms. Secondly, in a presentation called “HF propagation – what do the numbers mean?” RSGB Propagation Studies Committee Chair Steve Nichols, G0KYA unravels what terms such as Solar flux index, SSN, A and K index, and Solar Wind Speed mean and explains how to find the best HF conditions. You can watch both on the RSGB YouTube channel at youtube.com/theRSGB After serving for nine years, the RSGB Trophy Manager is retiring and the Society is looking for a new volunteer for this role. The position is part of the RSGB Volunteer Leadership Team, reporting to the Board. Working in close relationship with the three Contest Committees and the RSGB General Manager, the Trophy Manager looks after the RSGB's trophies arranges for their engraving and presentation to recipients and maintains the trophies' history. If you are interested in applying for the role or would like to find out more, please email gm.dept@rsgb.org.uk The G-QRP Club is running a fun event called the Summer Sizzler from Saturday the 17th to Sunday the 25th of June. This is not a contest, rather it is a relaxed on-air QRP event. It is an ideal opportunity to meet and greet new and old friends, to test your latest homebrew creations and to fill the bands with friendly QRP activity. The best logbook for the event will win the inaugural GM3OXX trophy. This will be decided upon by adjudicators and will not necessarily be awarded to the entrant with the most contacts. Unusual or remarkable logbooks have just as much chance of winning.

The Kp index never rose above three and was mostly ones and twos. This was no doubt helped by no M-class or higher solar flares and no Earth-directed coronal mass ejections. A large filament did break away from the Sun on the 12th of June, but luckily it was directed away from Earth. The solar flux index declined to the mid-140s after reaching 172 on the 6th of June. Paul, GM4ULS sent in an impressive log of 10m SSB contacts with Brazil, Argentina, Chile and Uruguay. These were mostly during the late afternoon although Paul says the openings often started around noon. F2-layer propagation was the first thought, but closer analysis suggests that these were more likely to be multi-hop Sporadic-E. If these contacts die out as we progress through the summer that should confirm that they were multi-hop Sporadic-E. Paul does have one tip. He listens to 27.555MHz, which is the SSB CB calling frequency. If he hears activity there he then fires up on the 10m band. Other DX this week has included VP6A on Ducie Island in the South Pacific. This DXpedition should be active until the 26th of June, so there is still plenty of time to work them. 8Q7KB in the Maldives should also be on until the 21st of June. Next week, the Space Weather Prediction Centre thinks the Solar Flux Index will start the week at around 150, rising to 170 as the week progresses. After a geomagnetic disturbance this weekend that may see the Kp index rise to four, and is likely caused by a coronal hole on the Sun's surface, we may expect quieter conditions next week with a maximum Kp index of two.   And now the VHF and up propagation news There has been some excellent Sporadic-E and super Tropo propagation during recent UK Activity Contest events. This is high-season for Sporadic-E, so it's worth a few notes to sharpen your DX potential. There are often two main 'windows' of activity: mid-morning and late afternoon or early evening. For early risers, there can be a surprise ‘window' of activity around 0600 to 0700UTC on some days and this is particularly useful for paths across the pole to Japan and the Pacific. The tendency is for openings to migrate westwards. Paths across Eastern Europe will be replaced by new paths to Italy or even Iberia as the particular event ‘window' migrates west. In this peak season the Sporadic-E operating ‘windows' may almost merge into one continuous activity period, especially on the lower bands such as 10m and 6m. As paths to Portugal fade, the new cycle may be starting with paths to Scandinavia and the Baltic. Multi-hop paths will be weaker than single-hop, and often more fleeting due to the complex geometry required, making the slower data modes frustrating. Add this to frequency spreading, and sometimes slick, fast CW can be the best mode if you can find the activity. The prolonged high pressure has provided some very good Tropo paths, particularly across the North Sea to Scandinavia. This may not be so reliable in the coming week as low-pressure moves in and offers heavy thundery showers as a source of rain scatter for GHz operators.  Meteor scatter and aurora are always possible, but Sporadic-E will probably be too much of a distraction. Sunday sees peak Moon declination but with apogee this coming Thursday, path losses will be at their highest.  144MHz sky noise is moderate until Saturday afternoon when the Sun and Moon are very close in the sky, spoiling the weekend for VHF EME. This “close to eclipse” condition persists until Sunday night after which noise levels are low to moderate for the rest of the week. And that's all from the propagation team this week.

GB2RS News Sunday the 21st of May 2023 The news headlines: Youngsters on the Air camp RSGB Board appointment RadCom Basics Editor   The RSGB has announced the team of young members who will be representing the Society and the UK at this summer's Youngsters on the Air camp. The event, hosted by the Hungarian Radio Amateur Society MRASZ, will take place in Gyor, Hungary between the 5th  and the 12th of August. The team is made up of team leader Alexander, 2E0FMZ and members Henry-James, M7HJR; Hannah, M7YYQ and Jake, M7JNS. You can read more about the camp and the team on the RSGB website at rsgb.org/yota-hungary The RSGB Board has decided to co-opt Ian Shepherd, G4EVK as a Board Director until the 2024 AGM. Please see the Board's explanation of this appointment on the Society's website at thersgb.org/go/boardcoopt The RSGB is sad to report that RadCom Basics Editor Lee Aldridge, G4EJB wishes to retire later this year. The RSGB thanks Lee for all his hard work and effort in the making of RadCom Basics. If you are interested in taking on the role of RadCom Basics Editor, please email radcom@rsgb.org.uk Last year, the RSGB was approached by the BBC to find experts to contribute to its planned series ‘The Secret Genius of Modern Life'. For episode one, which takes a look at the bank card, Neil Smith, G4DBN re-created the Great Seal Bug – a wooden seal, gifted to the US embassy in Moscow in 1945, and which contained a covert listening device. The technology developed for the bug was an early example of RFID, which is what allows contactless card payments to work. Neil has now released a series of fascinating videos on his YouTube channel which explain the history of the Bug as well as the mechanical design and machining needed to re-create it. You can find the videos in Neil's playlist on ‘Machining and Microwaves' and you can watch the original BBC Two programme on BBC Sounds – this episode is available for a further seven months. The RSGB National Radio Centre welcomes thousands of people through its doors each month and needs to expand its team of volunteers. If you are interested in becoming an NRC volunteer, you should enjoy meeting people and be prepared to work a minimum of one – preferably two – days per month. The team is particularly interested in recruiting new volunteers who are able to work at the weekend. The National Radio Centre has a fabulous set-up and full training on using the GB3RS radio station will be given. You will be joining a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information about volunteering, please email NRC Coordinator Martyn Baker, G0GMB via nrc.support@rsgb.org.uk Interest in QRP activity is as strong as ever in the worldwide amateur radio community.

The Kp index never got above three – a miracle given the recent disruption due to coronal mass ejections and coronal holes. The proton flux from the Sun has declined as well. However, an M9 solar flare on Tuesday from active region 3310, and numerous C-class flares, maybe a precursor to more flare activity next week. With a solar flux index in the 130s and 140s, HF conditions have been quite good. Daytime maximum usable frequencies over a 3,000km path have usually exceeded 21MHz, with 24MHz seeing occasional F2-layer openings, as well as sporadic E propagation. At the moment, the 10m band is mainly open to Sporadic-E propagation with more DX paths now locked out until the Autumn. This is in line with predictions, as the ionosphere changes in the Northern Hemisphere summer with a change to more diatomic elements, which are harder to ionise. So, will our luck hold out next week? The Space Weather Prediction Centre forecasts that the Solar Flux Index, or SFI, will decline slightly to the 120s and this weekend should be geomagnetically settled. However, it is predicting that the Kp index will rise again from the 23rd of May. It suggests that the Kp index may hit four or even five for a few days before becoming more settled again from the 30th. The US Air Force disagrees and thinks the SFI will be higher, perhaps hitting 145 and even 155 by the 28th. It agrees that we are in for more unsettled geomagnetic conditions from the 24th to the 28th, possibly due to a coronal hole rotating into an Earth-facing position. So, expect MUFs to decline if the Kp index goes up, with poor overall HF conditions. It is certainly looking like this weekend may see the best conditions for HF, so we suggest you get your DXing in right now, with 14 to 21MHz offering the best prospects.   And now the VHF and up propagation news The upcoming weather week will be predominantly high-pressure driven, with an elongated region of high pressure from the Azores to Scandinavia. However, there is still scope for a few blemishes and as we end the current week it comes as isolated showers, especially in the south and weakening fronts over north-western Britain. Early next week, a brief period with low pressure over the near continent will threaten some heavier rain for south-eastern areas. Concentrating on the high-pressure part of the story, this means Tropo is a strong player and will hopefully be in attendance for the 144MHz May Contest and 144MHz Backpackers Contest this weekend.  Remember that, in the summer months, Tropo becomes much weaker over the land during the stronger heating of the daytime sunshine but can become quite widespread overnight and around coasts. The rainfall component can lead to good rain scatter options, especially as the summer usually produces more intense rainfall, so performs better as a scatterer on the GHz bands. The other primary propagation mode is going to be Sporadic-E as we move into the peak summer months. Follow the position of jet streams on the upper air charts, shown on propquest.co.uk and described in a daily blog. Don't forget there are always modes like aurora and meteor scatter, which can add to the excitement, but will need to be checked each day. Moon declination is at its highest this weekend for the Dubus EME 10GHz and up SSB/CW contest, peaking on Monday. With apogee next Friday, path losses will continue to increase. 144MHz sky noise is moderate early next week becoming low by Thursday. And that's all from the propagation team this week.

GB2RS News Sunday the 14th of May 2023 The news headlines: Coronation activities RSGB Trophy Manager Women in Engineering Day   Although the Coronation itself has taken place, the RSGB's Coronation activities run until the end of June.

The good news is that the solar flux index was at 170 by Thursday, but the bad news was that we had two episodes where the Kp index hit five and there were at least five M-class flares.  At least one of these flares was responsible for a coronal mass ejection, or CME, which swept past the Earth on the 10th of May with a solar wind speed close to 700km/s. Although it was fierce, it was relatively short-lived and the Kp index was back to three on Thursday the 11th. The CME caused the maximum usable frequency over 3,000km to decline to around 21MHz at times on Wednesday, but by Thursday morning it was back up to nearly 28MHz. The high proton flux also caused problems on the 10th of May. The protons, mainly from CMEs, move down the Earth's magnetic field lines into the polar regions and cause massive ionisation of the polar D region leading to increased, or total, absorption of HF waves. This effect may last for as long as ten days and is called a Polar Cap Absorption event, or PCA. This affects signals going over the poles, such as the UK to the west coast of Canada and the USA, or to Japan and the far east. Meanwhile, we are now underway with the Sporadic-E season, so make the most of the short skip and potential multi-hop Sporadic-E DX on 14 to 28MHz. Next week, the Space Weather Prediction Centre has the Solar Flux Index declining slightly into the 150s. This is still more than enough to maintain DX on 21MHz and higher at times. It also predicts that the Kp index will be no higher than a stable 2 all week. However, that is hard to believe, with the level of solar activity at the moment, and we could reasonably expect the Earth to be hit with a CME or two at some stage. This could see the Kp index rising with the potential of reduced MUFs at times.   And now the VHF and up propagation news After a very unsettled end to the week, with lots of rain scatter reported, it will soon quieten down as a ridge of high pressure builds across the country to give some limited Tropo opportunities for the start of the weekend. This will not last long and by this evening, it will be heading back to unsettled with low pressure, heavy rain and rain scatter. This unsettled theme will last through the first half of the new week together with strong north-easterly winds. Thereafter, high pressure will build again for the second half of the week, providing further Tropo options. Keep a watch for Aurora, especially in view of the current unsettled solar state. CMEs will mean a very unsteady Kp index and anything higher than five should get your attention for auroral propagation. No significant meteor showers are expected this week, but QSOs using random meteors are always a possibility in the dawn hours. Likely to be of interest in the summer months ahead, there have already been Sporadic-E openings on 6m CW and FT8 into Europe. Early evening trans-equatorial 6m FT8 QSOs to South America, the Indian Ocean and the South Atlantic were reported from the UK last week. Check Propquest.co.uk for daily blogs and make use of the DX cluster and map plots to see where the actual centres of activity are located. Timings can be a bit random early in the season, but there tend to be two ‘openings' per day – one in the morning and a second during the late afternoon or early evening. Moon declination is rising, going positive again next Tuesday. But last Thursday's perigee means path losses are on the increase. 144MHz sky noise is low until Friday when the Sun and Moon are close in the sky for the whole Moon window. Things return to normal early on Saturday and sky noise is moderate. And that's all from the propagation team this week.

  GB2RS News Sunday the 23rd of April 2023 The news headlines: RSGB Coronation activities RSGB AGM announcements and videos RSGB Board Chair   The RSGB is delighted that Ofcom has confirmed that the callsign GB23C can be used for the RSGB's Coronation Special Special Event Station. Cray Valley Radio Society members led by Bob, M0MCV and Dave, G4BUO are organising the flagship amateur radio station that will use this callsign from the 3rd to the 8th of May. The Special Special Event Station will be on the grounds of the Old Royal Naval College, along the riverside in Greenwich. From the 10th of May onwards, the callsign will be available for individuals and clubs to use until the end of June 2023, and further details about this will be announced shortly. Ofcom has also kindly agreed to a block of 676 Special Special Event Station callsigns for the RSGB's Be a Connect activity for the Coronation. These are GB23BAA to BZZ, which will be available throughout May and June. More details on how to obtain one of these will be given next week, but meanwhile, you may wish to find a beacon site you could activate one or more times for this event. Finally, if you are planning outreach activities with local clubs and groups, take a look at the paper circuit template the RSGB has just shared on its website – go to rsgb.org/coronation and choose the coronation activity ideas tab in the right-hand menu. The RSGB's AGM was held online last Saturday, the 15th of April. If you missed the live event, you can see the results of the elections and follow links to the trophy awards and the construction competition winners on the RSGB website via rsgb.org/agm. You can also catch up on the full live stream or watch individual sections on the Society's YouTube channel. The RSGB has released separate videos of the outgoing President's review of 2022, its new short Convention promo, and the interesting presentation about preparing the GB2RS propagation reports by the RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. You can see them all in the RSGB 2023 AGM playlist on YouTube via youtube.com/theRSGB   Following the RSGB AGM on Saturday the 15th of April, a brief Board meeting was held to consider necessary appointments. The Board was aware that Stewart Bryant, G3YSX, who had been in a dual role since the recent resignation of Richard Horton, G4AOJ, had expressed a willingness to continue as Chair if required. It was agreed that Stewart should be co-opted to the Board under the terms of Article 37 and was asked to join the meeting. Stewart was then elected unanimously to serve as RSGB Board Chair until the 2024 AGM. This a reminder now that SOS Radio Week 2023 starts at midnight on the 1st of May and concludes at midnight on the 31st of May. It is an opportunity to support the many voluntary organisations in the British Isles whose members volunteer to save the lives of others at risk around the many miles of its coastline, and out at sea. These organisations include the Royal National Lifeboat Institution, the National Coastwatch Association and numerous independent lifeboat and coastal rescue groups.

UK and Ireland stations also send their District Code.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of April 2023 We had a surge in sunspot activity over the last week, pushing the solar flux index up to a maximum of 178, although it subsequently declined to 147. Solar flare activity was quite subdued after a frantic period from the 13th to the 15th that saw 40 C-class flares and two M-class flares erupt. This activity was mostly centred around active region 3282 in the northwest quadrant. Geomagnetic conditions were unsettled for a time around the 18th and 19th with the Kp index hitting a maximum of 4.3. This appears to have been due to enhanced activity from a coronal mass ejection and continuing coronal hole activity that saw the solar wind speed hit more than 600km/s and the Bz swing south. The critical frequency was down below 7MHz on the morning of Wednesday the 19th, which impacted near-vertical incidence skywave signals around the UK. This impacted maximum useable frequencies, which struggled to exceed 21MHz over a 3,000km path on Wednesday, although by Thursday they were back over 28MHz again. A critical frequency of more than 10MHz meant the 40m band was once again suitable for close-in contacts around the UK. There were many reports of DX being worked later on during the week, with Australia and New Zealand topping the bill on 18MHz and 28MHz. Next week NOAA has put a more positive spin on sunspot activity. The Solar Flux Index is predicted to be in the range of 168 to 172 for the first half of the week, falling to around 160 in the second half. But we could be in for a bumpy ride geomagnetically, with the Kp index predicted to hit five on Wednesday the 26th of April through to Monday the 1st of May. This may be due to the return of solar phenomena that occurred 27 days ago and saw the Kp index get up to 4.67. Meanwhile, a very large solar coronal hole, albeit positioned very south on the Sun's surface, and a much smaller one on its equator, threaten HF conditions this weekend. Keep an eye on the real-time solar wind from the ACE spacecraft for signs of a rise in speed and a southward-pointing Bz interplanetary magnetic field on solarham.net.  This could push to Kp index higher, perhaps to four.   And now the VHF and up propagation news The Sporadic-E season is nearly upon us. Remember it will usually activate on 28MHz and then higher bands will follow if the event intensifies. There have been some 50MHz FT8 paths flagged up on DXmaps.com, although some may have been tropo. The recent large high pressure centred over Scandinavia has been a bit subdued as regards Tropo. Much of the time, the air nearer the surface has been fairly dry with little sign of banks of sea fog over the North Sea, which would suggest better ducting potential.   We are now entering a phase with low pressure on the charts, initially over the south of Britain, but edging north for a time before drifting out across the North Sea.  This could produce some rain scatter on the GHz bands, especially should any heavy April showers develop. Early next week a ridge will edge south across the UK in a colder northerly weather pattern, so although high-pressure returns, it may not be especially good for tropo. The third changeover comes after midweek when a milder south-westerly returns with active fronts bringing rain and unsettled weather, especially to the north and west. This could mean further opportunities for rain scatter on the GHz bands and perhaps a hint of tropo in the Southeast towards the continent. Aurora and meteor scatter are well worth considering, and the Lyrids shower peaks on Sunday the 23rd. The message is to monitor meteor scatter frequencies and the clusters for signs of activity and, of course, try putting out a CQ call! Moon declination is positive and rising, meaning increasing Moon time and increasing peak elevation until peak declination on Tuesday. Moon apogee is next Friday so path losses increase all week. 144MHz sky noise is moderate to low. And that's all from the propagation team this week.

GB2RS News Sunday the 16th of April 2023 The news headlines: Nominated Board Director Vacancy Regional Forum Facebook pages SOS Radio Week   If you are an RSGB Member you still have time to apply for the RSGB Nominated Board Director vacancy. The RSGB needs a strong and effective Board and this could be your opportunity to be part of that. The deadline for applications is Monday the 17th of April. To find out more, go to the volunteer vacancies section of the RSGB website at rsgb.org/volunteers or, for an informal discussion, please email Nominations Committee Chair Stephen Purser, GW4SHF at nominations.chair@rsgb.org.uk The RSGB Regional Forum has created Facebook pages for each of the 13 regions. These pages focus on regional amateur radio communities and are moderated by members of the RSGB Regional Team. Whilst the pages share a similar style, they are very different in content. Selected posts are created by the RSGB moderators to maintain some news content from the RSGB, but the main content comes from clubs, individual licensees and also event organisers in those regions. The pages also provide a forum where anyone can ask for help with any part of the hobby. Clubs are positively encouraged to post news and events on the pages. You can find them on Facebook by searching for ‘RSGB Region' and the number of your local region, for example, ‘RSGB Region 1'.

According to a paper in Frontiers in Astronomy and Space Sciences, by solar scientist Dr Scott Macintosh, the solar maximum may now be coming between late 2023 and mid-2024. So, make the most of the higher Solar Flux Index now! Solar activity picked up nicely over the past week. The solar flux index rose to 154 and there were eight active regions on the Sun's visible face by Thursday the 13th. Nevertheless, daytime maximum usable frequencies, or MUFs, remain down a little, which has probably more to do with seasonal ionospheric changes than reduced sunspot activity. As we head towards Summer we will see the daytime F2-layer MUF decline further before it picks up again in the Autumn. We also saw some M- and C-class solar flare action this week, but this was not really enough to cause serious problems to the ionosphere. Next week NOAA predicts the Solar Flux Index will continue to increase, perhaps peaking at 160 around the 16th to 18th of April. Unsettled geomagnetic conditions are forecast for the 18th, perhaps with the Kp index rising to four. The forecast for International Marconi Day on the 22nd of April is for a Solar Flux Index of 155 and a declining Kp index of three, which bodes quite well for the event. In all, the Solar Flux Index is expected to be in the range of 140 to 160 for the rest of the month.   And now the VHF and up propagation news A big contrast is coming next week, so it's time to dust off the VHF gear again! The unsettled weather of this last week will make a complete swap over to more settled high-pressure systems next week.  Initially, on Sunday this will appear as a ridge over the North Sea from a large high over Scandinavia. This will then gradually extend across the country and will eventually be joined by a second high west of Britain.  The end result will be enhanced Tropo prospects in the coming week and potentially good conditions for the 23cm UK Activity Contest on Tuesday the 18th and the 4m UK Activity on Thursday the 20th. Those who enjoy rain scatter propagation in this current showery weather will have to look for other modes by Sunday, once the high pressure builds. As we are coming out of the Winter lull in meteor shower activity, with the medium-rate Lyrids peaking on the 23rd of April at 0100UTC with a Zenithal Hourly Rate, or ZHR, in the 20s, it's well worth a look for meteor scatter contacts. The end of April normally prompts a return of isolated Sporadic-E reports on the 10m band and perhaps even with data modes on 6m. The upper troposphere jet stream charts suggest it's got some potential, especially between Mediterranean countries although not quite so positive for paths nearer to home. The solar conditions may continue to offer a random chance of some aurora, so remember to keep an eye on the Kp index if it goes above five.   For EME operators, the Moon perigee is on Sunday so path losses are at their lowest. Moon declination is rising, going positive on Tuesday meaning increasing Moon time and increasing peak elevation passes. 144MHz sky noise is low, but the Moon is close to the Sun on Wednesday and Thursday meaning high Sun noise for those days. And that's all from the propagation team this week.

We were free of major solar flares with only one M-class flare occurring on the 20th. Geomagnetic conditions were mainly settled as well, but that could change this weekend thanks to a large coronal hole. The massive coronal hole on the Sun became Earth-facing on Thursday. A coronal hole is an area on the Sun's surface with open magnetic field lines, which allows plasma to flow out. They appear dark when photographed in extreme UV light. Although the bulk of the hole is south of the Sun's equator, a long finger reaches out to the equator, which makes it a potential threat to Earth. All eyes will be on the Kp index over the weekend as we expect it to increase, possibly dramatically as the solar wind impacts us. Solar wind speeds are likely to be in excess of 600km/s and continue into the weekend, resulting in isolated G1 storm levels. Keep an eye on solarham.net for updates. We are now at the spring equinox, so it is prime time for auroral activity. The spring equinox traditionally brings greater solar activity which results in an increased frequency of auroral displays. It is also a prime time for north-south HF paths, such as the UK to South Africa, and the UK to South America. Next week, the US Air Force predicts that the solar flux index will decline slightly to bring it into the range of 130 to 140. Once the weekend's solar storm declines, we may expect a few days of relatively calm geomagnetic conditions before another period of unsettled space weather is predicted for Thursday the 30th and Friday the 31st. This could see the Kp index rise to five once again.   And now the VHF and up propagation news The overall unsettled nature of the current weather pattern is likely to continue for much of the period through to the end of next week, except for a brief ridge of high pressure crossing the country after the weekend. This might offer the only tropo potential for VHF operators. The rest of the time will probably be beset by bands of rain, showers and, at times, strong winds and introduce the prospect of some rain scatter on the GHz bands. It's a week to focus on fleeting tropo, rain scatter and aurora as modes of choice. As we said earlier, the aurora is worth looking out for since the solar conditions are still very disturbed. As usual, good indicators are the Kp index values, which ideally should be five or greater to get our attention. The meteor shower calendar is still in its quiet period, and with no major showers to look for, it would be best to try your luck with random meteors, which tend to peak just before dawn. The Sporadic-E season has not started yet but is getting closer, say from mid-April on 10m, perhaps. For EME operators, Moon declination reaches maximum next Tuesday meaning long Moon availability windows. Path losses increase throughout the week and 144MHz sky noise starts out moderate, falling to low next weekend. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 16th of March 2023 Last week was split in two, in terms of HF propagation. The first half of the week was characterised by excellent high-band conditions, with many people commenting on how good things were. The Kp index was low, there was a lack of solar flares and the solar flux index was high – perfect for HF. There were reports of openings to Hawaii and Alaska on 10m and Bob, MD0CCE said 10m had been open to the Pacific every night for the last five or six days. But it didn't last and by Wednesday it all went pear-shaped. The Earth was hit by a fast-solar wind with a southward-pointing Bz on Wednesday the 15th, which increased the Kp index to 5.67. Its impact on the ionosphere was quick and very damaging, to such an extent that the two ‘local' Digisondes at Fairford and Chilton couldn't detect the F2 layer, leaving their traces blank. It happened again on Wednesday evening, with the Kp index hitting 5.67 once again. Luckily, it didn't last long and the Kp index was back down to less than two by the morning and the MUF over 3,000km was back over 28MHz by mid-morning on Thursday. Next week, NOAA predicts that the solar flux index will remain in the range of 135 to 145. Unsettled geomagnetic conditions are forecast for the 20th but, as we know, anything can happen at this point in the solar cycle. Look for a low Kp index but, above all, get on the bands and see what you can work! And now the VHF and up propagation news The unsettled weather pattern seems likely to continue through the coming week driven by an undulating jet stream over the British Isles. This will mean, for yet another week, there is unlikely to be much good Tropo. It's not all bad news though, since the unsettled part of the weather story may introduce some rain scatter on the GHz bands. The mention of jet streams should, in a month or so, raise the promise of some Sporadic-E activity, which is often geographically related to the position of jet streams. It's probably a bit early for that, although it could be worth considering a look at 10 and 6m as we move towards the end of the month. 10m, and 6m if you're in the far South West, can also give some good Trans Equatorial propagation, this time of year. This is typical of the changeover period from the southern hemisphere to northern hemisphere Sporadic-E activity. As usual, the chance of aurora is still around, so keep a watch out on the clusters or spaceweather.com for all the latest news. Early-morning random meteors should stay on the checklist too. For EME operators, moon declination is low but rising, going positive again on Wednesday meaning Moon availability windows will lengthen. The Moon is at perigee today, so path losses are at a minimum. 144MHz sky noise is low this week, apart from the whole of Tuesday when the Sun and Moon are close to an eclipse. It is perhaps worth reminding new licensees that preparing a good list of HF and VHF beacons to monitor can be worthwhile, especially in quieter times before the summer Sporadic-E season gets underway. And that's all from the propagation team this week.

GB2RS News Sunday the 18th of December 2022   The news headlines: Train the Trainers courses RSGB Convention videos Planning Advisory Committee recruitment   After a forced break during Covid, the RSGB will be restarting Train the Trainers courses in the spring of 2023. It is hoped that three courses will be run across the country. The team would like to run the courses where demand is greatest, rather than arrange three courses where there is no demand. If you are an existing trainer, or would like to become one, and would like to attend a course during the year, please contact  g7lfc@rsgb.org.uk  The team would also like to hear from clubs that are willing to host a course so that it can match demand with availability. For further details about the course, what it covers and what is required from hosts, please visit rsgb.org/train-the-trainers The RSGB has released four individual presentations from its 2022 Convention which cover a wide and interesting range of topics. Philip Lawson, G4FCL gives an introduction to test equipment whilst Phil Catterall, G4OBK talks about adventure radio in Europe. Taking a look back into history, Dr David Abrutat provides a fascinating insight into Bletchley Park and the Y Services between 1939 and 1945. Finally, as a link with December's YOTA month, young radio amateurs Dan McGraw, M0WUT and Hamzah Shah, 2E0HXS share their experiences and learning from the YOTA summer camp in Croatia this year. Find these and other RSGB Convention presentations on its YouTube channel at youtube.com/theRSGB The RSGB Planning Advisory Committee assists RSGB Members with planning advice. It is looking to recruit additional committee members to help with this valuable service. You should be involved with, or retired from, a discipline associated with the planning process or have a good working knowledge of the planning process.

Using all modes on the 1.3GHz band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 16th of December 2022 Things hotted up last week with a healthy increase in sunspot activity. The number of sunspots ramped up, giving us a solar flux index of 165 by Thursday. The other upside was the fact that geomagnetic conditions were quite settled with the Kp index remaining between one and three all week. There were some downsides. We have had an increase in the number of solar flares, with a total of 14. Of these, 11 were M-class. This is all happening around active region 3165, which is now a prime candidate for an X-class solar flare, the most powerful. There were reports of poor HF propagation on the morning of the 15th, which can possibly be attributed to the solar flares on the Sun. The graph of the maximum useable frequency, measured at Dourbes, looks rather like a roller coaster ride, with the extrapolated MUF over 3,000km being more than 38MHz at 9.15am and below 19MHz 20 minutes later. The moral of this story is that if HF propagation seems to fail just give it 20 minutes and see if it recovers. According to NOAA, the high solar flux index won't continue for much longer. It predicts that the SFI will reduce to between 115 and 120. The Kp is also predicted to stay low, at least until the 22nd when it is forecast to rise to five, possibly because of a returning coronal hole from 27 days ago. And finally, both the Chilton and Fairford Digisondes are offline at the moment, so please select Dourbes if using Propquest.co.uk And now the VHF and up propagation news The cold weather will be displaced as a temporary mild spell brings higher temperatures, plus wet and windy weather, during this weekend.  Eventually, colder westerly air with showery troughs will return from the west, but still with further bands of rain. There will probably be some good rain and snow scatter opportunities for the GHz bands. Tropo looks a bit thin, although there may be a brief enhancement on Sunday morning to France and the Low Countries but this will be gone by the afternoon. The other modes like meteor scatter and aurora are still a consideration, but much less predictable. With the Geminids meteor shower past its peak, there are two minor showers to look out for this week. The Leonis Minorids are active from the 5th of December to the 4th of February, reaching a maximum on the 20th of December with a low Zenithal Hourly Rate, or ZHR, of around five. The Ursids are active from the 17th of December to the 26th of December reaching a maximum on the 22nd of December, also with a low ZHR of around 10. Moon declination went negative on the 17th, so Moon windows will continue to shorten and zenith angles decrease. EME path losses are falling as we head towards perigee on Christmas Eve. 144MHz sky noise is increasing all week and on Friday we get close to an eclipse, so it will be very high during the whole Moon pass. Lastly, to repeat the ‘heads up' from last week about midwinter Sporadic-E, it is still worth mentioning since it usually becomes a reference after the event, and it would be nice to be there before it happens! So, employ the usual check of HF and VHF clusters from 10 to 4m and use www.propquest.co.uk and its EPI or Es probability index plots to see where the most likely areas for Es are located. Like summer events, rarer mid-winter Es are often associated with powerful jet streams and this unsettled weather is a good source for these. And that's all from the propagation team this week.

GB2RS News Sunday the 20th of November 2022 The news headlines: December is YOTA Month Transatlantic Centenary Tests 2022 RSGB Construction Competition   December is Youngsters On The Air month. This is an opportunity for individuals, clubs, groups and schools to run an amateur radio station with the aim of getting youngsters active on the air. The RSGB is inviting applications to host the special callsign GB22YOTA. To register your interest email Jamie, M0SDV at yota.month@rsgb.org.uk with details of the activity you are planning. Please include your name, organisation and the callsign of the Full licensee who will host the activation. To see the GB22YOTA activation schedule, visit the GB22YOTA page at qrz.com. The RSGB is hosting the Transatlantic Centenary Tests 2022 on the HF bands for the month of December. Unlike those of the 1920s, which consisted of one-way communication, this event will encourage worldwide two-way communication with UK and Crown Dependency stations. There will be a series of awards available for making QSOs with those who are activating historic RSGB callsigns. The Club Log team has kindly agreed to provide the supporting infrastructure for this. The Society is looking for RSGB members to take part and make this historic event a success. You can read more on page 54 of the December RadCom and be inspired by the RSGB Convention Transatlantic Test presentation on the RSGB YouTube channel. To find out how to take part, go to rsgb.org/tct Do you enjoy amateur radio construction? Would you like to try making something for the first time? The RSGB's Construction Competition welcomes entries in four categories – Beginners, Construction Excellence, Innovation, and Software. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded for the winner of each section, with a bonus for the overall winner who will also be declared the winner of the Pat Hawker G3VA Trophy. The deadline for entries is 1 March 2023 so you have plenty of time to construct something during the long winter evenings. To find out more, including how to enter, see the full details on the RSGB website at rsgb.org/construction-competition Most of you will have experienced RF interference problems of one sort or another over the years. In this world of advanced digital technology and increasing wireless connectivity, the probability of interference is high and increasing rapidly. This is giving rise to an ever-increasing pollution of the radio spectrum which is threatening all wireless communication. To counter these problems, the RSGB EMC Committee makes the relevant authorities aware of issues by taking measurements and surveying any available documents and reports. The committee needs volunteers to help with that task. Deep technical knowledge or experience in EMC work is not necessary, but ideally, candidates should have a good understanding of radio. If you are an RSGB member and would like to help, please contact emc.chairman@rsgb.org.uk The RSGB's National Radio Centre at Bletchley Park will be closed from Tuesday the 22nd of November until Friday the 25th of November for the upgrading of essential equipment and the installation of a new fire alarm system. The Society apologises for any inconvenience this causes. The RSGB's Examination Standards Committee has published its annual report, covering the operation of amateur radio exams during the calendar year of 2021. Search for Examination Standards Committee on the RSGB website at rsgb.org and you can read the report in the minutes, papers and reports sub-page.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 18th of November 2022. The good HF conditions continued last week with a low Kp index and a reasonable solar flux. But is that all about to change? The problem is a large coronal hole in the Sun's southern hemisphere, which became geoeffective on Thursday. The hole is at mid-latitude, so is not completely in line with Earth. But its large size means that we could see a strong solar wind, which may hit the Earth this weekend, potentially pushing the Kp index up for a couple of days at least. Sunspots have been adequate rather than outstanding. The main active groups have now rotated out of view, but there are some new ones just appearing over the Sun's limb. The HF bands have been excellent and many newer amateurs have had their first taste of 10m in full flow. Next week NOAA predicts that the solar flux index could decline to the range 105-115. The Kp index is predicted to rise to four at least until the 22nd. We may then get respite for a day or two before it rises again to three or four. In other words, we have probably seen the best of the settled HF conditions for a while. Just what effect the enhanced solar wind and increased Kp index this weekend will have on maximum usable frequencies is hard to predict. Typically, an increased Kp index can result in reduced MUFs, but whether we will see it impact 10 metres, especially with the predicted lower SFI, we will just have to wait and see. And now the VHF and up propagation news After last weekend's excellent tropo, with 24GHz propagation from the South East of England to the near continent, we now have a seemingly never-ending period of unsettled weather continuing through the coming week. This is driven by a strong jet stream flow across the Atlantic. Since it's a low pressure and rain scatter period once again, it's worth a reminder that, although we are way out of season with regards to Sporadic-E, it can still be seen on the foEs graphs on the Propquest.co.uk website and can be particularly useful for the LF bands. Focusing back on VHF and above, the prevalence of low pressure during the week suggests Tropo is unlikely to entertain us. The only modes remaining to discuss are meteor scatter as we slowly fade from the peak of the Leonids, and finally the prospect of a random aurora if we have further disturbed solar conditions. This week's active meteor showers are the Alpha Monocerotids which are active until November the 25th and reach a low ZHR maximum on Monday the 21st of November. Also, the November Orionids, are active until December the 6th but don't peak until the 28th. Moon declination went negative on Saturday so Moon windows will shorten and zenith angles decrease. Path losses are still low but with perigee on Friday, path losses will fall all week. 144MHz sky noise slowly increases, reaching a maximum of over 2,500 Kelvin on Friday. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 21st of October 2022 We had another great week of HF propagation, helped no doubt by a very low geomagnetic Kp index meaning the ionosphere remained settled. Despite the solar flux index declining to 113 by Thursday, 10m has been highly active with openings every day. We have had good daily 10m openings, even out as far as the west coast of the USA for well-equipped stations. Next week NOAA predicts that the solar flux index will continue to remain in the 110-120 range. This is not extreme but would be enough for good propagation on all of the upper HF bands if we don't have any geomagnetic disturbances. A rather large coronal hole is rotating into view and should become Earth-facing on the 21st. This is fairly low on the Sun's face so might not impact us as badly as a coronal hole on the solar equator would. But, nevertheless, its size suggests that any disturbance might be long-lived. If so, expect its plasma to hit Earth late Saturday or Sunday. NOAA also predicts that the Kp index will rise on Wednesday the 26th of October with the index rising to five. Quite what will cause this is unclear, although it could be the return of an active region that took the Kp index to six 27 days ago. Once that clears, we may expect good conditions on 10m to hopefully continue, so make the most of them. And now the VHF and up propagation news The current transition to changeable autumnal conditions is fully complete and proving very difficult to shift. This means that the breezy unsettled weather with low-pressure systems pushing fronts across the country will continue during the period. This may produce some rain scatter options, although it's not a big 'shout-out' compared to the intense thunderstorms of high summer. There will be some high pressure nearby over the continent, but it's not likely to be a big Tropo player and remains largely out of reach from the UK. One minor meteor shower, the Leonis Minorids peaks on Tuesday the 24th of October, but the ZHR is low. Aurora could crop up on occasion during the coming week and, after recent activity levels on 6m, there is still a chance of Sporadic-E. This recent activity just shows that we should probably learn to regard it as an option, especially on FT8, even in the nominal ‘close season' for Es. Moon declination goes negative today, Sunday, so Moon windows continue to shorten as the week progresses. With perigee next Saturday, path losses will fall throughout the week. 144MHz sky noise starts low, but there is a partial solar eclipse on Tuesday the 25th so that day will be an EME washout. After the eclipse, the noise rises slowly from 380K to around 3000K next Saturday, making it a noisy week for EME. And that's all from the propagation team this week.

Anti matter, matter Shadow, light Black, white. Neither can exist without the other, they represent opposing extremes, they are fundamental to every thing. Without the prism [eye, mind, brain] splitting and filtering the light as separate frequency, every thing would appear in its most fundamental form. The eye, brain or mind provide the mechanism to perceive the frequencies between those extremes. The story of frequency has played out over the last 100 years, think about consumer electronics they have progressed perfectly in-line with the RF spectrum ... beginning with radio moving through TV, microwaves, personal computers, video games, mobile phones, internet, wifi etc etc. Look at computers, the speed of the processors has moved through the ranges to a band of UHF [ultra high frequency] 300MHz to 3GHz, not much has changed in terms of speeds for over a decade. RF spectrum shows the human progression, the story of technological development, from the lower natures to the higher. An expression of the human condition. Fundamentally though, I believe that it is all as simple as black and white and the visible light spectrum is used to our detriment. Certain frequencies of color will command an action RED = STOP or a RED + BLUE = STOP, but i dont know why. Red is the “just do it” [sounds familiar] and the Blue is the “why”, this is represented clearly in the signs and symbols that adorn almost all road sides. Certain public officers use sirens and flashing red & blue, it is confusing because you are seeing the action to stop but the blue of the higher mind may question. Further, some uniforms also carry a checkerboard black & white pattern, as a lapel, again representing the extremes with no context thus could infer confusion. Lastly, the game of chess at the basic level each “character” or “piece” is featured in mythology, stories and royal titles. A reset of the game, the check mate, in which all pieces are placed back into position.

Using all modes, stations exchange their 4-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 1st of July 2022. Last week was not a good one for HF propagation in general. There were many complaints from amateurs about poor conditions that can be explained by a combination of low solar flux levels and unsettled geomagnetic conditions. The SFI started the week last Sunday at 102 but then dropped to 98 the following day. It subsequently continued to drop, reaching 92 by Thursday. At the same time, the Kp index reached five and it continued to be unsettled into Monday. The effects on the ionosphere were not good, with maximum usable frequencies over a 3,000km path struggling to reach 18MHz. Conditions improved as the week went on with F2-layer MUFs back into the 21MHz region by Thursday. This is fairly typical of Summer ionospheric conditions, leaving Sporadic-E as the likely main propagation mode on 10 metres until the Autumn. Next week NOAA predicts that the solar flux index will start to climb again, perhaps peaking at 140 by the 11th of July. Geomagnetic conditions are predicted to be stable with an average Kp index of two, until the 10th when it could reach four. As long as we don't have any coronal mass ejections during this time this could mean slightly better F2-layer conditions next week. As always, Sporadic-E may provide loud short-skip signals on the upper bands. Watch out for multi-hop Es paths which are harder to predict. And now the VHF and up propagation news. With VHF National Field Day, this weekend we would all like conditions at their best, and with the Sporadic-E season still in full swing, that's a possibility. The position of the jet stream is often instrumental in defining the directions that perform for Es and this weekend it looks to be a close-by jet stream over the near continent. This means paths towards central and southeast Europe plus the Baltic and Scandinavia. You might be able to get some notion of how it's developing by Googling and looking at the ionosonde from Dourbes in Belgium for spikes in the foEs trace. With low pressure close to Scotland over the weekend, it's only southern UK under a weak ridge that will see any Tropo. This will typically be better overnight and around the coasts for paths into the continent across the North Sea or the English Channel. So unless you are on the coast, your tropo options will diminish early this Sunday morning once the solar heating starts to break down the overnight temperature inversion. The UKAC 144MHz contest on Tuesday evening looks a better prospect with high pressure nudging towards western Britain and a chance that conditions may be slightly up, even for more northern stations. With some showery episodes likely, rain scatter is always a possibility, but decaying as the high moves in later. The clusters should tell you if aurora or random meteor scatter are viable options. Just one meteor shower this week, the July Pegasids active from the 4th of July to the 14th, but its Zenithal Hourly Rate is low at around five. Meteor showers in July are at their best around the end of the month, particularly the Southern delta-Aquariids, peaking on the 30th of July. The maximum ZHR of this shower is around 25 over two days. The radiant of this shower is above the horizon in the UK during the night and early morning. Moon declination goes negative this coming Wednesday so expect lower peak elevation and shortening Moon visibility windows for EME. Path losses are dropping as we head towards perigee a week on Wednesday. 144MHz sky noise is low all week. And that's all from the propagation team this week.

GB2RS News Sunday the 26th of June 2022 The news headlines: RSGB joins IARU Region 1 meeting GB70D on air from the Isle of Man Tonight@8 on Monday RSGB volunteers and staff contributed to the IARU Region 1 Interim meeting at Friedrichshafen on Thursday the 23rd of June. The meeting covered topics across HF, VHF and UHF as well as Microwave and EMC matters. This included the latest state of preparations for WRC-23 where agenda item 9.1B on the protection of satellite navigation systems, such as Galileo in the 23cm band, was of prime interest. Slides showing the current state and this potentially significant threat to the radio amateur and amateur satellite services have been published on the RSGB special focus page at rsgb.org/wrc-23. The IARU, supported by the RSGB, continues to work hard to reduce any impact. The Queen's Platinum Jubilee station GB70D is based on the Isle of Man. On Tuesday the 28th, it will be based in the grounds of Government House. It is hoped that the Lieutenant Governor of the Isle of Man and Lady Philippa will participate for several periods during the day. The station plans to operate on 2m, as well as SSB and CW on most bands from 40m up. Operations start around 9.30am. Tonight @8 will take place on Monday, the 4th of July. This is the final lecture before the summer break. Peter Duffett-Smith, G3XJE will be looking at Radio waves and antennas…and all that. His presentation covers a range of antenna-related information so there should be something for everyone. Tonight@8 webinars are live-streamed on the RSGB's YouTube channel, YouTube.com/thersgb. The 98-year-old 200kW Alexanderson alternator, callsign SAQ, will not be able to air on Alexanderson Day, Sunday the 3rd of July. This is due to difficulties in obtaining components in the ongoing maintenance work. The Alexander Association welcomes visitors to the museum on the 3rd from 10am to 4pm. Together with the World Heritage Grimeton Radio Station they will offer many activities for the whole family during the day. There will be two transmitter startups with SAQ, but without any transmission over the antenna. National society in Iceland, IRA, reports on the renewal of special authorisation to use 50MHz. Icelandic licensees have been granted increased power licenses in the 50-50.5MHz frequency range until the 31st of September. Full licensees are allowed to use up to 1kW and Novice licensees up to 100W.

Next Sunday, the 3rd of July, the 3rd 144MHz Backpackers contest runs from 1000 to 1500UTC. Using all modes, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 24th of June 2022. As predicted, the solar flux index fell back this week, but it didn't fall as low as experts predicted. On Thursday, it stood at 129, but with three sunspot groups about to rotate off the visible surface, it looks like it may now fall lower. We are now well and truly into the summer season for HF propagation, which can be characterised as providing lower maximum usable frequencies during the day, but higher MUFs at night. Sporadic-E remains the most common mode of propagation on the higher bands, with F2-layer MUFs over 3,000 kilometres generally not exceeding 21MHz for most of the day. But more on Sporadic E in the VHF segment of this report. The good news is that 20 metres stays open later, often providing paths over 3,000km up until midnight. The higher bands, that is 17 metres, 15 metres and perhaps 12 metres, may generally provide good paths to South America in the evenings, with 20-metre paths being the last to close. But we're afraid we may have to wait until September to see good reliable paths into North America on HF once again. Next week, NOAA predicts that the SFI will remain around the 100 mark, so we may expect lower MUFs again, apart from Es openings. Geomagnetic conditions should generally be quiet with a maximum Kp index of two once we get over any disturbance this weekend due to a high-speed solar wind stream. And now the VHF and up propagation news. The recent very warm and humid weather has produced some occasional Tropo with the British Isles being on the edge of high pressure, mainly over the near continent. This may still happen occasionally in the coming week, but the fundamental characteristic for next week is low pressure and unsettled weather over the UK. This will produce some rain, with thunderstorms a possibility, and rain scatter will crop up as a useful mode on the upper GHz bands at times. The many online weather radar displays will allow you to keep a track of storms as they develop. When low pressure is centred over the country the showers may be longer-lasting and not decay overnight, so this period looks more promising than the usual mainly daytime shower distribution. The Sporadic-E season is in full swing, but in a rather restrained way since openings have been fairly limited and often fleeting. The presence of jet streams on the weather charts is a good indicator of regions where Es is more likely and the coming week offers a good variety of options, so if Sporadic-E is hard to find then perhaps other parameters may not be optimal; for example, the meteor input is a crucial component in the development of Es. Check the daily conditions for jet streams on the Propquest.co.uk EPI maps and Es blog. The June meteor showers, mentioned last week, continue into early July so keep checking meteor scatter conditions between the Es. With the Moon at maximum declination on Wednesday, Moon windows are long this week. Today, Sunday the 26th of June, the Moon is at apogee, or its furthest point from Earth, so path losses are at their highest, and for around four hours after UK Moonrise on Wednesday the Sun is close to the Moon so noise will be high at that time. And that's all from the propagation team this week.

Solar activity reached a new peak for this cycle this week, with the solar flux index hitting 180 on Thursday the 19th. This was partly down to the very large active region 3014, which is almost big enough to be seen with the naked eye if suitable precautions are taken. To put this into perspective, the sunspot number is 147, which is higher than the estimated smoothed maximum prediction of 115 for Cycle 25. Meanwhile, geomagnetic conditions have been favourable with the Kp index moving between one and three since Monday. This is all good news and is being reflected in the band conditions at the moment, with round-the-world echoes being heard on some DX signals. Make the most of them as there is the ever-present threat of X-class solar flares to contend with. Two active regions, which have already been emitting X-class flares, are about to rotate into view.  The USAF predicts that the SFI may stay above 175 until at least Wednesday, before declining into the sub-150 range. This is at odds with the NOAA prediction, which never really thought that the SFI would get to 180 last week. In other words, it is anyone's guess what we will get! Don't forget that Sporadic-E is also livening up the upper HF bands and providing strong short-skip signals. These can often link into multi-hop Es or join with F2-layer hops to give surprise long-distance DX that is hard to predict. We have never had it so good for some time and let's hope it continues into the Autumn when HF can really come into its own. And now the VHF and up propagation news. It seems we are in a typical summer unsettled pattern with areas of thundery rain and heavy showers drifting north from France. This will obviously keep rain scatter as an option. Summer can also be a time of strong Tropo, especially around coasts and over the adjacent seas. This is because a strong temperature inversion can develop over cool seas with areas of mist and fog at sea level overlain by warm dry air blowing off the continent. These paths are likely to persist over long periods, particularly across the North Sea, English Channel and Irish sea with extended options south across Biscay. To finish off we have the early stirrings of the 2022 Sporadic-E season, which is starting to show some promising signs, and not just on digital modes. A major controlling influence is often associated with the presence of jet streams nearby and the upper air forecast charts suggest that there should be some reasonable opportunities during the coming week. Don't forget that jet stream upper air charts are available daily with commentary on the Propquest.co.uk website. There is no major meteor shower this week, but we are at the tail end of the Eta Aquarids shower, which began in late April and is generally regarded as petering out next weekend. Eta Aquarids are associated with Halley's Comet. But don't expect to see the comet until 2061! The Moon will be waning throughout this week with decreasing declination and increasing distance as it moves towards apogee and that, therefore, leads to increasing path loss. Moon libration will be low.  This week's TK/HB9CRQ Corsican EME microwave DXpedition should enjoy favourable lunar path conditions if the weather cooperates. And that's all from the propagation team this week.

GB2RS News Sunday the 24th of April 2022 The news headlines: Two new GB2RS broadcasts Take part in SOS Radio Week VMARS nets The RSGB GB2RS News Service is delighted to announce two new broadcasts on Sundays. With a nod to how it all started back in 1955, we have introduced a transmission using amplitude modulation. This takes place in the 80m band on 3650kHz at 8 am UK time from the station of G4JBD in Bedfordshire. The intended coverage is the Midlands and the South East of England but it may be heard more widely when propagation is favourable. For those in the South West Glasgow area who are busy on Sunday mornings, we are now offering an evening broadcast on 2m. Delivered by 2M0GUI on 145.525MHz FM, the transmission is at 6.30 pm UK time. Every year thousands of people get into difficulty around our coast. Thousands of unpaid volunteers swing into action to save and rescue them. SOS Radio Week celebrates the work of these selfless volunteers. Amateur radio stations get on the air to raise awareness of the invaluable work of the Royal National Lifeboat Institution, National Coastwatch Institution and the many independent lifeboat and rescue organisations around our coasts. The activity starts at 0000UTC on the 1st of May and concludes at 2359UTC on the 31st. Participants are encouraged to become an official Registered Station and make as many contacts as possible, mentioning the reason for the event during their contact. For further details visit sosradioweek.org.uk The Vintage Military Amateur Radio Society will be displaying at the Blackpool Rally today. They have regular nets on 3.615MHz at 8.30 am on Saturdays using AM and at 8 pm on Wednesdays using USB to facilitate the use of ex-military equipment. On Fridays, the frequency remains as 3.615MHz at 7.30 pm using LSB. More at www.vmars.org. As part of the forthcoming Jubilee celebrations, the RSGB has announced further details of its GB70 special event station activities. The seven SES callsigns will be active across the Jubilee weekend, from the 2nd to the 5th of June, on multiple bands and modes by various clubs. After that weekend, these special callsigns will be available for activation by RSGB affiliated clubs or individual RSGB members until the 28th of June. Each callsign has a volunteer coordinator responsible for allocating operating slots in a published schedule. They will also collect the log files from those who have been activating the calls. For further information see the GB70 page in the RSGB Jubilee web section at rsgb.org/jubilee. Provisional results for the 2021 IARU Region 1 Marconi Memorial VHF Contest are available.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 22nd of April 2022. Last week was characterised by solar flares – lots of them! There were numerous strong flares, although the majority occurred in the early hours and so didn't affect the ionosphere over Europe. Solar flare events can cause short-lived radio blackouts as the energetic photons penetrate deep into the D-layer. Solar activity during the past 30 days has increased drastically with five of the top 10 strongest flares of Cycle 25 detected during this period alone. We have also had very strong sunspot activity with the solar flux index peaking at 160 on Thursday the 21st. The current crop of four sunspot groups probably means we can expect the SFI to stay high until at least early next week. NOAA predicts the SFI will stay above 130, but we may get even higher figures for a time. It also predicts a maximum Kp index of two next week, although that could easily rise if we get hit by matter from any incoming CMEs, which are getting more prevalent as the cycle continues. The good news is that, at the time of writing, it didn't look like we will get any coronal hole activity. There have been numerous reports of good conditions on the higher bands - 21, 24 and 28MHz – including openings to TX5N on the Austral Islands. Braco, 8Q7DX, who is on holiday in the Maldives, has also been worked. There have also been some signs of early Sporadic-E with very loud openings to Spain on 10 metres. So if the SFI stays this high and we don't get many geomagnetic disturbances it could be a good week for HF. And now the VHF and up propagation news. We have a classic spring start to things with low pressure over the near continent, aided by the increasing warmth of the spring sunshine, while colder regions to the north become home to high pressure near Iceland. Between the two, we will have a strong and cold-feeling east to northeasterly wind over the UK; not really the setup required for Tropo, since the strong winds and turbulence destroy any temperature inversion. The changes come along after this weekend as the low weakens and a ridge of high pressure extends south across the country with much lighter winds and a chance of Tropo, especially overnight. It is possible that isolated showers may offer a little rain scatter, but not a high probability. It would be better to consider possible aurora and meteor scatter as your exotic modes. In this closing part of April, the best is within reach, since Sporadic-E is a serious possibility on 10m and perhaps 6m. Use the beacons and clusters to guide you, but if you start to adjust to your summer operating rule of checking for Es mid-morning and late afternoon or early evening, then Es QSOs will soon come. The Winter minimum of meteor show activity is at an end with Sporadic meteor rates increasing towards their usual maximum in late summer. The Lyrids shower has passed the peak but continues to be active until the 30th. Moon declination starts the week negative with low peak moon elevations and short visibility windows but turns positive again on Thursday. Path losses are on the increase again as we are past perigee. 144 MHz sky noise is low all week except Saturday afternoon when the Sun and Moon are close in the sky for the five hours leading up to Moonset at approximately 1900hrs. And that's all from the propagation team this week.

GB2RS News Sunday 25th July 2021 The news headlines: RadCom Basics latest issue NRC Net to close DARC reports survey results   The latest issue of RadCom Basics is now available from the RSGB website. In this edition, you can read about split frequency operation and more on logging and eLog, amongst other subjects. RSGB Members can read previous editions of RadCom Basics by going to rsgb.org/radcom-basics. You can register at the same address to receive notification of subsequent issues as they become available. As life returns, we hope, to a degree of normality, the regular weekday National Radio Centre net will cease. Instead, at 10.30 am on 3.737MHz an informal gathering will take place for those that want to call in and have a QSO. The RSGB would like to thank Nigel, G4RWI, who ran the NRC 80m net every day in 2020 and on weekdays throughout 2021. There were over 400 nets with hundreds of callers and thousands of QSOs. The German national society, DARC, has published the results of the amateur radio survey they conducted for the IARU. They had 550 respondents. The results are available via the DARC website, in German. There are some similarities with the RSGB's survey, as well as opinions on FT8 and licensing. On the third weekends of April and May, the IARU Region 1 organised the first 50MHz and 70MHz Machine Generated Modes-only contests. The official results are now published at iaru-r1.org. Congratulations to G4PLZ, who achieved top placing in both contests in the 6-hour section. His best DX on 50MHz was in excess of 1700km, and he achieved almost 1600km on 70MHz. In line with Government advice, Bletchley Park has relaxed their requirement for mask-wearing and social distancing. Their visit-booking system is still in place. Whilst the RSGB acknowledges that the legal requirement of Covid precautions has been reduced, we wish to take a more cautious approach at the National Radio Centre. As space in the NRC is restricted and there is limited airflow, the wellbeing of visitors and volunteers is paramount. This means many Covid precautions such as face coverings and social distancing within the NRC will still be required. The GB3RS station is still unavailable for visiting amateurs, but we will bring you news when this situation changes. As GB2RS continues to expand, it is a pleasure to extend a warm welcome to two new newsreaders. Leigh, M5GWH has joined the existing team in the Stoke-on-Trent area. Essex newsreaders have been joined by Richard, G0NAD. In addition to reading a brand-new broadcast on 70cm, Richard is also assisting with the 4m service in that area. And listeners in the north of England may like to note that the 145.525MHz broadcast from MM0JNL is now additionally covering Northumbria. The QSL Bureau sub-manager for the G4T-Z group is retiring and a replacement volunteer to distribute cards to this active sub-group is urgently needed. If you are an RSGB Member with time, a little space, some basic computer skills plus the desire to help your fellow members, the bureau would like to hear from you. You can find out more by emailing qsl@rsgb.org.uk. And now for details of rallies and events Before travelling to any rally or event, please check the event's website as there may be alterations or cancellations due to the current restrictions. Finningley ARS Car Boot will be outdoor only on the 25th of July, with doors opening at 10 am. It is located near M18 junction 2, Doncaster. Admission is £3.

Now the contest news With different parts of the UK having different lockdown restrictions, please make sure you follow the appropriate regulations. Keep yourself and fellow amateurs safe. The 24-hour Islands On The Air Contest ends its run at 1200UTC today, Sunday the 25th. Using CW and SSB on the 3.5 to 28MHz bands on which contests are permitted, the exchange is signal report, serial number and your IOTA reference. Stations on the UK mainland are IOTA reference EU-005; a full list can be found at iota-world.org. The UK Microwave Group Contest runs from 0600 to 1800UTC today. Using all modes on the 5.7 and 10GHz bands, the exchange is signal report, serial number and locator. On Monday, the 6th FT4 Series will run between 1900 and 2030UTC using the 80m band. The exchange is your 4-character locator. On Tuesday the SHF UK Activity Contest takes place between 1830 and 2130UTC. Using all modes on the 2.3GHz and up bands, the exchange is signal report, serial number and locator. The Worked-All-Britain 144MHz Low Power Contest will take place on Saturday the 31st of July between 1400 and 1800UTC. The input power is limited to 10 watts and the full rules are on the WAB website. Entries are to be with the contest manager by the 10th of August. Due to the easing of restrictions, the mobile and portable categories will be resumed; but the organisers ask that entrants ‘please act sensibly'. On Saturday, the Fourth 144MHz Backpackers Contest runs from 1400 to 1800UTC. Using all modes, the exchange is signal report, serial number, locator and postcode. The 144MHz Low Power contest also takes place on Saturday from 1400 to 2000UTC. Using all modes, the exchange is signal report, serial number, locator and postcode. Next Sunday, the 1st of August, the 432MHz Low Power Contest runs from 0800 to 1200UTC. Using all modes, the exchange is signal report, serial number, locator and postcode. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 23rd of July Sunspot numbers were down at the start of the week but increased dramatically as the week went on. By Thursday the solar flux index was up to 94 with a sunspot number of 86. There were six active regions visible on the Sun. Although many of these sunspots were quite small and not very complex, they all contributed to the higher solar flux, which is now nudging 100. The region that was active on its last rotation, 2835, and was responsible for multiple coronal mass ejections, appears to have quietened. Nevertheless, the Sun may well be more active next week as some of the regions have produced low-level C-class flare activity over the past few days.  NOAA reports that solar cycle sunspot progression over the past several months has actually been ahead of the cycle 25 forecast. This may bode well for the future. HF propagation remains dominated by Sporadic-E, with daily openings on the upper bands. F2-layer propagation is at seasonal levels, with openings up to 14 and sometimes 18MHz being recorded. We are not seeing much in the way of 21MHz F-layer propagation, but that will kick in as we head into Autumn. Thirty metres, or 10MHz, remains a band to check overnight with MUFs over a 3,000km path typically exceeding 10MHz. Due to all this activity, NOAA has upped its forecast for the coming week. It now has the solar flux index at 85 next week, rising to 90. The geomagnetic prediction is for a maximum Kp index of 2, possibly due to a lack of coronal holes. However, it is too early to say whether we may have any solar flares and CMEs from the new regions currently rotating into view. And now the VHF and up propagation news. After some very good days of Tropo recently, it seems that the picture will look very different in the coming week. The decline of the high pressure will be complete by this weekend and heralds a week of unsettled weather with showers or longer periods of rain. On the upside, this puts rain scatter back on the agenda for the microwave operators. Sporadic-E is still a good contender for DX although heading into August usually thins out the activity. The meteor input to E layer ionisation should keep hopes alive of renewed openings. The jet stream placements are mainly favouring the path to the south into Iberia initially, before moving east later to open up other more eastern parts of Europe. Around we go again into another lunar cycle with negative, but increasing declination, this week. This of course means that we'll see the Moon for longer as each day progresses. Declination goes positive on Thursday, but losses will rise daily after last Wednesday's perigee. Random or sporadic meteor rates are approaching their annual maximum around now, and the Southern delta Aquarids meteor shower is under way. This has a broad ZHR peak of 25 running from the 26th of July through to the 31st. Note that in Europe, the shower radiant is only above the horizon during the night and early morning. There are some other minor showers peaking next week, so we should see excellent meteor scatter conditions. And that's all from the propagation team this week.

GB2RS News Sunday 4th July 2021 The news headlines: Join Monday's Tonight @ 8 NRC closure for tree felling GM0GMN to lead IPA Amateur Radio Section Don't forget to join the RSGB's Tonight @ 8 webinar on Monday evening. RSGB EMC Chair John Rogers, M0JAV will explain how to assess your station against ICNIRP EMF levels. The EMC Committee has been working hard to help all radio amateurs understand more about how to comply with the new Ofcom licence conditions. So take this chance to hear from an expert and ask questions. Tonight @ 8 will take a break in August and then will be back with another great programme for the autumn. To find out more about this and previous webinars, go to rsgb.org/webinars. The RSGB National Radio Centre at Bletchley Park will be closed on the 5th and 6th of July. This is due to the large tree in the immediate vicinity of the NRC being felled. It is planned to re-open on Thursday the 8th as usual. Note that the NRC is not open on Wednesdays. Following the very sad passing of Regional Representative Tom Reilly, G0NSY, the International Police Association has appointed James, GM0GMN to lead their UK Amateur Radio Section. James is keen to make contact with current and former members of the group and to encourage new members. To contact James, see QRZ.com. Following the update from Ofcom to their guidance What you need to know as an Amateur Radio user, the RSGB has updated its calculator to version rsgb10a. This can be found on the EMF pages of the website at rsgb.org/emf. Please treat this as a beta release and report any problems to m0jav@rsgb.org.uk. The main changes are to implement band dependent antenna gain and the low power compliance condition in line with Ofcom's change to guidance. The other changes made by Ofcom to their calculator were already in the RSGB version. Have you ever thought about taking up an awards challenge as part of your amateur radio activities? Whether you enjoy HF or VHF/UHF, the RSGB awards are open to everyone, whatever your age, licence level and personal interests. Along the way, you will learn more about propagation, experiment with equipment and make tweaks to your station to maximise performance. Awards encourage you to push yourself further. The RSGB has launched a new web page that highlights the stories of radio amateurs who enjoy chasing awards. Take a look and be inspired by them at rsgb.org/award-stories. The GB2RS service is seeking a newsreader to cover the Western Isles of Scotland. You would be joining an existing team as a reserve reader and there are opportunities for more than one applicant to broadcast the News on Sunday using HF, VHF or UHF. You should be an RSGB Member and have good coverage of the region. If you want to find out more without obligation, please contact the GB2RS Manager at gb2rs.manager@rsgb.org.uk. A date for your diary now. The popular Churches and Chapels on the Air event will take place on the 11th of September. Most activity takes place on the 80 and 40m bands. Please register your station with organiser John, G3XYF, see QRZ.com. And now for details of rallies and events We heard from several rally organisers that their events will not be taking place this year. Rugby ATS regrets that it is not able to run its rally this year, but they look forward to seeing everyone next year on Sunday the 21st of August 2022. The organisers of the Welsh Radio Rally, which was due to take place in October, have said that it will return in 2022. They would like to thank the traders and visitors that have supported them over the years and look forward to seeing everyone again in 2022. Also cancelled are the East Sussex Wireless Revival and McMichael rally & boot sale, both originally planned for next Sunday, the 11th. On a much brighter note for later this month, the Finningley ARS Car Boot bring & buy is scheduled to go ahead on Sunday the 25th of July. You can check for updates at g0ghk.com/cbr21 Finally, the Wiltshire Radio Rally, Electronics Fair & Car Boot Sale is planned to go ahead on Sunday the 1st of August.

Now the Special Event news Coventry ARS is running two special event stations until May 2022 to celebrate Coventry being the City of Culture. GB1COC & GB8CCC will be running most days, with GB8CCC passing between members of the club. Dates and times will vary. Now the contest news With different parts of the UK having different lockdown restrictions, please make sure you follow the appropriate regulations. Keep yourself and fellow amateurs safe. This weekend is the RSGB VHF National Field Day. It runs for 24 hours until 1400UTC today, the 4th. Using all modes on the 50MHz to 1.3GHz bands, the exchange is signal report, serial number and locator. Please note that with the current Covid-19 restrictions, teams with multiple operators should ensure they are following the regulations in their area. Today, the 4th of July, is the 3rd 2m Backpackers contest. It runs from 1100 to 1500UTC. Using all modes, the exchange is signal report, serial number and locator. On Monday the CW leg of the 80m Club Championships runs from 1900 to 2030UTC. The exchange is signal report and serial number. On Tuesday the 144MHz FM Activity Contest runs from 1800 to 1855UTC. It is followed by the all-mode 144MHz UK Activity Contest from 1900 to 2130UTC. The exchange for both is the same, signal report, serial number and locator. On Wednesday, the 144MHz FT8 Activity Contest runs from 1900 to 2100UTC. The exchange is your report and 4-character locator. On Thursday it is the turn of the 50MHz UK Activity Contest, running from 1900 to 2130UTC. Using all modes, the exchange is signal report, serial number and locator. Next weekend the IARU HF Championship runs for 24 hours from 1200UTC on the 10th to 1200UTC on the 11th. Using CW and SSB on the 1.8 to 28MHz bands, where contests are permitted, the exchange is signal report and ITU Zone. For the UK that is 27. The UK Six Metre Group Summer Marathon runs until the 1st of August. Just exchange your 4-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 2nd of July. Well, NOAA certainly got the sunspot predictions wrong last week. It said that the solar flux index would be in the range 76 to 78 with a maximum Kp index of two. As it turned out, the SFI ended up way higher than this, peaking at 94 on Thursday. Active sunspot regions 2835 and 2836 ended up being bigger and more vigorous than predicted, pushing the sunspot number to a high of 53. This bodes well for the future and could mean that Solar Cycle 25 is now truly under way. The CDXC group has reported 10m FT8 openings to China, Japan and South Korea, plus 10m and 12m openings to the Caribbean and South America. Sporadic-E has started to tail off a little as we enter July and this is probably not helped by an increase in the Kp index to four on Wednesday night. The major IT outage at the University of Massachusetts Lowell continues. This means there is still no ionosonde data on the Propquest.co.uk website for foF2 graphs at the moment. Luckily, you can still access the live Chilton ionosonde data directly at ukssdc.ac.uk/ionosondes, although you may need to register. A check on Thursday showed that the critical frequency mid-morning over the UK was around 4 to 4.5MHz, meaning a maximum useable frequency over a 3,000km path of about 16.5MHz. Other than Sporadic-E openings, we can't expect the MUF to rise much further until the Autumn. NOAA predicts the solar flux index will decline from around 92 to perhaps 85 next week, as regions 2835 and 2836 rotate off the visible face of the Sun. Geomagnetic conditions are predicted to remain relatively calm with the Kp index at two to three. And now the VHF and up propagation news. Tropo opportunities have gradually diminished over the tail end of the week just gone. We had a super North-South duct up the East Coast on Wednesday evening allowing a close-to 700km 10GHz Tropo QSO between Keith, GM4ODA/P at IO99IV in Shetland and Neil, G4DBN in IO93NR, who's almost at sea level on the Humber estuary. We are now left with what is essentially a low pressure-driven weather pattern, with a small low crossing southern England early in the week. This will mean that periods of rain or heavy and possibly thundery showers are likely, so good for rain scatter on the GHz bands. The main development will see low pressure over the British Isles or just to the west. The accompanying upper air pattern suggests a jet stream becoming established just to the south, over the near continent. This is a perfect location for supporting Sporadic-E paths into much of Europe, should other factors be in favour. The jet stream strength also looks to be a bit stronger again, which is another good sign. Just keep in mind that the band will seem dead if you don't call CQ! Mid-morning and late afternoon to early evening are going to be the most profitable times to do that. Moon declination is positive and rising again so Moon visibility windows will lengthen. With apogee on Monday, path losses will be high. There are no significant meteor showers until the end of the month, so continue to look around dawn for the best random meteor scatter opportunities. And that's all from the propagation team this week.

In today's episode: Samsung has partnered with Google to bring Wear OS to its smartwatches with its own version called One UI Watch, which promises faster performance, better syncing and battery life. We have leaked renders of the forthcoming Z Flip3 and Galaxy Buds2, confirming most things we knew so far. Infinix has a concept device which won't go on sale anytime soon, but features 160W super fast charging, colour-changing back glass, curved display and periscope zoom with up to 60x magnification. OnePlus Nord 2 has gotten a leaked render, thanks to 91Mobiles, which shows the same front display (minus the extra selfie camera) and a back camera grid that looks like the OnePlus 9. Qualcomm has announced its latest high-end chip, the Snapdragon 888+, which has CPU clock speeds of up to 3GHz. Nothing's first TWS earbuds will be unveiled on July 27th. ACCC has warned people to keep their AirTags from children, as the easily-accessed coin-cell battery could be swallowed by the little ones. Plus: Lenovo's got some new tablets and a smart clock.

GB2RS News Sunday 27th June 2021   The news headlines: Covid-19 affects VHF NFD Tree-felling to interrupt National Radio Centre Durham is 13 Colonies bonus station   Covid restrictions are extending into July and this means that VHF NFD is taking place with more controls in place than the organisers were hoping for. It is still viable to run the contest on the 3rd and 4th of July, but it will require some additional precautions and control to be exercised by entrants. All entrants, group organisers and individuals involved must fully comply with all local Covid-19 restrictions and advice that apply at the time of the event. This includes, but is not limited to, social distancing, meeting people outside of their household/bubble and travel restrictions. Any enclosed operating space such as a car, caravan or a tent without two open sides is treated as an indoor location and will be subject to the tighter limits on the number of people visiting that space for the duration of the contest. The rules are different in each of the devolved nations and are regularly changing. So please satisfy yourself that you are compliant with your local rules at the time of the contest. The RSGB National Radio Centre at Bletchley Park will be closed on the 5th and 6th of July whilst a large tree is felled in the immediate vicinity. Booked entries to Bletchley Park itself are unaffected. Durham & District ARS is participating as one of the bonus stations in the 13 Colonies Special Event. The event began in 2009 as a way of celebrating American Independence with the original 13 colony States of 1776. Since the UK was a major historical player in the Revolutionary War, GB13COL from England will present an added challenge. The event will run from 1300UTC on the 1st of July to 0400UTC on the 8th. The primary focus of the event will be the HF bands, including VHF & UHF for QSOs using SSB, CW, FM and various digital modes. There is also an opportunity to exchange QSL cards with all 13 Colony State stations, plus the bonus stations. For further information go to 13colonies.us. A polite reminder now concerning the frequencies used each Sunday by the RSGB's GB2RS News service. The News is intended for all radio amateurs and listeners, and a clear frequency ensures that it may be heard as widely as possible. The national frequencies on HF are 1990, 3643, 3650, 5398.5 and 7127kHz. Some of these frequencies carry a succession of broadcasts from more than one location. On VHF and up, the principal frequencies for more localised broadcasts throughout the day are 70.425, 145.525 and 433.525MHz. Most amateurs appreciate that no individual or organisation has ownership of any frequency on the amateur bands, it has always been ‘first come first served'. But, in the case of GB2RS, there is a restriction on how far the broadcast is allowed to move to avoid interference. So, whether you're a club planning to set up a regular net, a contest station rapidly jumping frequencies, or someone just looking for a spot to call CQ, if it's a Sunday please spare a thought for the RSGB's volunteers who are trying to deliver the news. The full GB2RS frequency list and transmission times can be viewed at rsgb.org/gb2rsschedule and many webSDRs label the News spots on their waterfall displays. The RSGB would like to thank amateurs for respecting these frequencies. The Youngsters On The Air Contest's first round is complete and the claimed results have been posted on the YOTA website at contest.ham-yota.com. Worldwide participation was very good. In the YOTA-class categories, more than 100 entries were from contesters between 7 and 25 years old, and three entered as short wave listeners. There were more than 600 entries of participants above the age of 25, with the oldest participant at age 87. The next round will be on the 8th of July. Today, the 27th is the final day of the three-day Ham Radio World event. Instead of physically meeting in Friedrichshafen participants are able to listen to lectures, look at exhibiting companies and view the virtual exhibition site. Go to www.darc.de and click on the Ham Radio World advert at the top of the page, then chose the English language option for more information. The vintage Alexanderson alternator transmitter in Grimeton, Sweden, will conduct its annual Alexanderson Day transmission on the 4th of July using its usual callsign, SAQ. The CW transmission will be on 17.2kHz, CW. Startup and tuning for the first SAQ transmission will take place at 0830UTC, with a message transmission to follow at 0900UTC. Startup and tuning for the second SAQ transmission will take place at 1130UTC, with a message transmission to follow at 1200UTC.

It runs from 1400UTC on the 3rd to 1400UTC on the 4th. Using all modes on the 50MHz to 1.3GHz bands, the exchange is signal report, serial number and locator. Please note that with the current Covid-19 restrictions, teams with multiple operators should ensure they are following the regulations in their area. Next Sunday, the 4th of July, is the 3rd 2m Backpackers contest. It runs from 1100 to 1500UTC. Using all modes the exchange is signal report, serial number and locator. The UK Six Metre Group Summer Marathon runs until the 1st of August. Just exchange your 4-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 25th of June. We had another week that was largely dominated by Sporadic-E openings. It is worth pointing out that Sporadic-E can and does have a blanketing effect on HF signals, which can prevent them from reaching the F2 layer of the ionosphere. This means that predictions created by a program like VOACAP or ITURHFPROP can often be over-optimistic. VOACAP and ITURHFPROP do not take into account seasonal Sporadic-E and, in any event, the localised and changing nature of Sporadic-E clouds means it would be very hard to make monthly median predictions. During the summer months, take computerised propagation predictions with a pinch of salt. While short-skip propagation may be better at times, longer distance signals may in fact be worse than the predictions. Sunspot region 2833 has now rotated out of view off the Sun's edge and we can expect the solar flux index to decline from the 80 reached on Thursday. The good news is that at least two returning regions, 2830 and 2831, will be turning back into view over the weekend. A lack of coronal holes means geomagnetic conditions should remain quiet over the next week. NOAA predicts the solar flux index will be in the range 76-78 with a maximum Kp index of two. Lastly, due to a major outage at the server in the States at the University of Massachusetts Lowell, there is no ionosonde data on the Propquest.co.uk website foF2 graphs at the moment. The server has been subjected to a cyber attack and restoration of the academic services rightly takes priority; the graphs will be there as soon as the server is back online. And now the VHF and up propagation news. It's another week of mixed fortunes for VHF/UHF users, with a tendency for high pressure over northern areas after the unsettled weather moves through during the tail end of this week. It eventually leaves an area of low pressure close to, or over, southern areas and this remains in place for much of the next week. Towards the end of the week, another low will drift south across eastern areas. The best chance of Tropo is over Scotland and Ireland, while unsettled and potentially thundery weather will be a good source for some rain scatter activity in southern areas. The Sporadic-E prospects are looking a bit quiet at first, but as a new upper-low moves into the southern UK and France, we should see prospects improve again into next week, particularly for paths to Iberia and the eastern Mediterranean. Moon declination goes positive again on Friday, so peak Moon visibility windows and peak elevations will increase. Path losses will rise throughout the week. The June Bootids meteor shower peaks today. And that's all from the propagation team this week.

GB2RS NEWS Sunday the 25th of April 2021 The news headlines: 400 lockdown nets for Hambleton Martin, G3YJO on Radio Four Free Contest University online   On the 22nd of April, Hambleton ARS passed the 400th consecutive day of a net on 2m FM. It was started during the Covid-19 lockdown to keep members and amateurs in the area in touch and able to summon help or assistance if required. The net starts at 11 am on the calling frequency and usually moves to S18 if clear. All amateurs are invited to join in and, so far, over 70 different stations have been logged. The net controller is usually Tony, G3MAE, who has ‘missed’ less than five days of operating during that time. A Cabin Fever award is available for any station taking part, issued by Tim, G0TYM via email, see QRZ.com. This week, Radio 4’s programme, The Life Scientific, featured Professor Sir Martin Sweeting, G3YJO. He is the pioneer of microsatellites. He talked about his progress from UOSAT 1 via Cubesats to the Surrey Satellite Technology sale to Airbus. You can hear the interview online via BBC Sounds. The Dayton Hamvention may have been cancelled for 2021, but the Contest University will still take place on the 20th of May. It will be held online, free of charge, via Zoom, starting at 1300UTC. Registration is open at contestuniversity.com. There is an IET webinar about amateur radio on the 12th of May starting at 7.30 pm. You might be interested to see how the presenter, Phil Gould, presents the hobby to the audience. It is a free lecture, entitled To the other side of the world and beyond: An appreciation of amateur radio. Go to events.theiet.org and scroll through until you reach the 12th of May.

The UK Six Metre Group Summer Marathon runs from the 1st of May to the 1st of August. Just exchange your 4-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 23rd of April. Last week was marked by solar flares, perhaps giving us a taste of things to come as the solar cycle progresses. The Kp index hit four on Monday after the weekend’s high of five. But luckily things then calmed down and we have been seeing the Kp index down to two overall. There was even one three-hour period where it was zero. We have had more sunspots this week, which are always welcome. Region 2817 has now rotated off the Sun’s visible disk, but regions 2816 and 2818 have been very active. They pushed the solar flux index to 86 on Monday, but it was back down to 78 by Thursday. The first M-class solar flare since the 29th of November 2020 was observed around region 2816 in the Sun’s southeast quadrant at 2342UTC on the 19th of April. Luckily, this occurred at night so had zero effect on the ionosphere over the UK. A coronal mass ejection, or CME, associated with this flare has been assessed as passing just behind Earth, but the Met Office’s space weather team said there was a slight chance of a glancing blow in the coming days. A long-duration C-class flare around the same region occurred at approximately 0415UTC on the 22nd and looks to have produced a possible Earth-directed CME. If this is the case, we may expect the Kp index to rise, perhaps early in the weekend, resulting in reduced maximum usable frequencies. HF conditions have been relatively lacklustre this week, although there has been some activity on 10m FT8. EA has been copied, perhaps via early-season Sporadic-E, and Bob, VP8LP on the Falkland Islands has put in an appearance during the late afternoon, as have numerous South American stations. Daytime MUFs over a 3,000km path have generally struggled to exceed 18MHz at times, although there have been the odd DX openings on 21, 24 and even 28MHz. Next week NOAA predicts the SFI will remain low, perhaps even dropping into the high 60s. Geomagnetic conditions are predicted to be generally quiet with a maximum Kp index of three. But do look out for further solar flares, which could cause short-lived disturbances on HF and the strong possibility of coronal mass ejections that could impact the Earth one or two days later, depending on the solar wind speed. And now the VHF and up propagation news. Conditions are starting out with a Tropo frame of mind into this weekend, but there are hints of a small low tracking south across Scotland at the end of this weekend, and probably across the North Sea to establish low pressure to the east of the UK after midweek. This will probably mean that the Tropo period is weakened gradually and with further lows near southern Britain at the end of the week, there is likely to be a subtle shift to rain scatter propagation for the GHz bands. We keep flagging up the forthcoming Sporadic-E season and clusters show it's just getting underway in an FT8 sense. It will no doubt start to show up with 10m or 6m beacons soon, so worth checking your favourite beacon list regularly. If you haven’t got one yet, this would be a very good time to save a list of half a dozen frequencies for each band in the rig memories to make sure you can check for openings easily. From a jet stream perspective, initially, paths to Scandinavia look promising and by midweek probably more towards southeastern Europe and Ukraine. Moon declination went negative today, so Moon windows are short and the Moon is at low elevation. The upside is that we have low path losses with perigee tomorrow (Monday). The April Lyrids meteor shower produced some good meteor scatter QSOs last week and with the Eta-Aquarids set to peak on the 5th of May, the new meteor scatter season is well underway. Look at the usual frequencies for the mainly digimode activity. And that’s all from the propagation team this week.
