GB2RS News Sunday, the 28th of September 2025 The news headlines: What are your must-see presentations at this year's RSGB Convention? The RSGB invited the MP for Buckingham and Bletchley to the RSGB National Radio Centre for a private visit Listen out for today's special 70th anniversary GB2RS broadcasts Before we begin today's news bulletin, we would like to share a special message from the RSGB President Bob Beebe, GU4YOX, to mark the 70th anniversary of GB2RS. Bob says, “It is with a profound sense of respect and appreciation that today we mark the 70th anniversary of the GB2RS News service. Since 1955, volunteers have given their time and their voice to keep our radio community informed, connected, and inspired. For many of us, GB2RS has been a constant and familiar presence in our radio lives. On behalf of the RSGB, I extend my heartfelt thanks to all who have played a part in this remarkable story for the last seventy years. Today, we honour their legacy and reaffirm our commitment to the values and spirit that the GB2RS News service so proudly represents.” And now we move to today's news items. The programme for this year's RSGB Convention has nearly 50 presentations for you to enjoy, including leading industry speakers such as Mike Walker, VA3MW from FlexRadio and Hans Summers, G0UPL from QRP Labs. There will also be well-known names such as Neil Smith G4DBN, RadCom Technical Editor Peter Duffett-Smith GM3XJE, Brian Coleman G4NNS and Walt Hudson K4OGO, known to many as ‘Salty Walt'. This annual RSGB event is your only opportunity within the UK to have access to this level of knowledge, learning and networking opportunities. As well as a packed full lecture programme, there will be nearly 20 special interest groups in attendance, so if you are thinking of pursuing a different area of the hobby, this is the perfect time to explore your options. To guarantee a place, you will need to purchase a ticket online via rsgb.org/convention before advance sales close on Sunday the 5th of October. Buying your ticket online not only guarantees your place, but it also saves you money when compared to on-the-door ticket prices. If you are arriving on Friday, why not join a private tour of Bletchley Park at 2.30 pm, which has been arranged especially for Convention attendees. In addition to this, and new for this year, RSGB National Radio Centre volunteer Patrick, 2E0IFB, will be running an informal introduction on getting started with low-earth orbiting satellites. The RSGB Convention takes place from the 10th to the 12th of October at Kents Hill Conference Centre in Milton Keynes. The RSGB was pleased to welcome Callum Anderson, MP for Buckingham and Bletchley, to the RSGB National Radio Centre at Bletchley Park last week. Callum enjoyed seeing the history of radio, watching live CW contacts and listening to his voice coming back from space, having been relayed via a satellite. Callum was invited to meet a small group of senior RSGB representatives who emphasised the important role of amateur radio in encouraging young people into an engineering career. Getting involved in Science, Technology, Engineering and Maths activities gives a great foundation that could lead some young people to follow in the footsteps of radio amateur pioneers who led the development of many wireless technologies that we rely on today. Most importantly, the visit gave the RSGB an opportunity to show the problems that ElectroMagnetic Disturbance can cause to wireless reception. Examples of EMD include household appliances, Broadband FTTC and green energy from solar panels and windfarms, where the signal levels are thousands of times stronger than the expected levels given in ITU recommendations. EMC Chair John Rogers M0JAV and Board Chair Stewart Bryant G3YSX explained that unless the year-on-year increases in background noise are stopped, many critical services and infrastructures could be impacted soon, just as the amateur radio bands are today. The RSGB looks forward to meeting again with Callum, who is the Parliamentary Private Secretary for Science, Innovation and Technology. Don't forget to listen out for three special one-off broadcasts from the RSGB National Radio Centre today. The broadcasts are part of the celebrations, which are taking place to mark the 70th anniversary of GB2RS. Listen out at 1 pm, 2.30 pm and 4 pm. Go to rsgb.org/gb70rs for details of frequencies and newsreaders. All listeners are welcome to join the pre- and post-News nets, which will be operating using the special event station GB70RS. The RSGB LoRa high-altitude balloon launch took place on Saturday, the 20th of September and was a great success despite tricky weather conditions, which included rain and high winds. The balloon soared at a peak altitude of 48,556 feet before landing in a remote location in the Thursden Valley. Winners of the competition to win a £200 Moonraker voucher will be announced at the RSGB 2025 Convention on Sunday, the 12th of October.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 25th of September Last week was good for HF propagation for a number of reasons. Firstly, we are now entering autumn, which offers better propagation prospects than summer. Secondly, the solar flux index has remained high at up to 184 as of last Thursday, the 25th. We had a week of near-normal geomagnetic conditions, with a low Kp index, no Earth-directed coronal mass ejections, and a relatively quiet solar wind. These have all combined to give excellent HF propagation, including openings on the 10m band using FM and transatlantic 10m contacts being possible in the afternoon. The maximum usable frequency, or MUF, over a 3,000km path, according to Propquest, has mainly been in excess of 30MHz during daylight hours. The KQ2H repeater in upstate New York, with an output frequency of 29.620MHz, has been loud at times in the afternoon and is a good indicator of HF propagation. Expect it to get better as we enter October. Other US stations have also been heard on the 10m band using FM, including one in Ohio. Steve, G0KYA, was surprised to hear the GB3XMB 10m beacon on 28.287MHz from Waddington, Lancashire this week. Steve remarked that it is 175 miles to Norfolk as the crow flies. He said that the signal didn't sound like backscatter, so that's quite a distance for 10m ground wave. Another DX worked, according to CDXC, included FP5KE, the St. Pierre and Miquelon DXpedition. The station could be heard on everything from Top Band to 10m. V6D in Micronesia has been worked on the 40 and 17m bands using CW. Other highlights include D2USU in Fiji on the 12m band using FT8, and 9Y49R in Trinidad and Tobago on the 10m band using FM. Next week, NOAA predicts the solar flux index may fall to the 159 to 170 range. Geomagnetic conditions are predicted to be poor tomorrow, the 29th, with a Kp index of 5, and again between the 3rd and 5th of October, also with a predicted Kp index of 5. Expect decreased MUFs for a few days until the ionosphere recovers. And now the VHF and up propagation news from G3YLA and G4BAO The next week or so looks to be typical for autumn. It will be a mix of Atlantic weather systems bringing lows and their fronts, which may offer some rain scatter for those on the GHz bands. The other side of the coin is areas of high pressure or mostly weak ridges, in this case mainly affecting the south and east of the country. This is the point where Tropo operators can move in with paths probably favouring the North Sea and Scandinavia up to this weekend and then across to the continent and down to Spain during the coming week. It is worth remembering that Tropo can exist throughout the 24 hours across water and along coasts like the North Sea and English Channel, although the portion of a path overland can weaken during daytime. The meteor scatter prospects remain in the random territory, so they are best in the early morning. Recent activity with geomagnetic disturbances suggests that aurora should continue to be part of the operating list in the coming week. Check for a hollow note or warble on HF signals and for a Kp index greater than 5, then consider turning your VHF arrays to the north. For EME operators, Moon declination reaches its minimum tomorrow, the 29th, so from then on, we will see lengthening Moon windows and increasing peak elevation. The Moon's distance from Earth started to decrease after apogee on Friday, the 26th, meaning path losses are falling. 144MHz Sky noise will be high today, the 28th, and peaks at around 2800 Kelvin tomorrow, the 29th, before dropping back to low for the rest of the week. And that's all from the propagation team this week.

A Clare woman has escaped injury after her boat forming part of a global aid mission to Gaza was allegedly struck by projectiles in a drone attack. Poet and Activist Sarah Clancy who lived in Ballyvaughan for over a decade was on board 'The Spectre' which is among 51 boats in the Global Sumud Flotilla, which is currently in international waters between Greece and Libya. Spain's Prime Minister Pedro Sanchez has now said he will join Italy in sending a military warship to protect the international flotilla. Clancy claims here her boat was struck four times with objects that emitted smoke smelling like sulphur, while the next day the boat's VHF radios were jammed. She says it was a life-threatening situation.
GB2RS News Sunday, the 21st of September 2025 The news headlines: Secure your ticket for the RSGB 2025 Convention before online ticketing closes A reminder to identify yourself clearly when operating The RSGB Outreach Team launches its first official DMR Youth Net Tickets for the RSGB Convention at Kents Hill Conference Centre in Milton Keynes are still available to purchase online, but hurry as advance sales close on Saturday the 4th of October.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 18th of September 2025. Last week we said that it looked like someone had thrown a switch on the Sun and all the sunspots had vanished. Well, this week we're pleased to report they're back! We have eight sunspot groups, spread evenly throughout the Sun's hemispheres. Interestingly, the northern hemisphere sunspots are close to the equator, which is what you would expect at this point in the latter part of the solar cycle. The southern spots are somewhat higher in latitude, perhaps indicating that there might still be the potential for a double peak. On Thursday the 18th, the solar flux index stood at 147 and the Kp index at 2. This suggests that HF conditions might be pretty good, at least until the next geomagnetic disturbance. There have been no M- or X-class solar flares over the past week. The solar wind speed dropped from a high of 800 kilometres per second on Tuesday the 16th, to a more reasonable 538 kilometres per second on Thursday the 18th. However, the Bz has been pointing south at times, which can cause problems with a raised Kp index. The maximum useable frequency, or MUF, over a 3,000km path generally allows for operation between 21 and 24MHz during daylight and 7 and 10.1MHz at night. At 0845UTC on Thursday the 18th, a quick check of the NCDXF beacons on 21.150MHz showed reception of CS3B in Madeira and 4X6TU in Israel. On 24.930MHz, 4S7B in Sri Lanka, ZS6DN in South Africa, and CS3B in Madeira could be heard. On 28.200MHz the only audible beacon was 4X6TU in Israel. The NCDXF beacons are a quick way to check worldwide HF propagation in just three-minutes per band, from 20 to 10m. For more details visit ncdxf.org/beacon HF DX this week has included FP5KE on St Pierre and Miquelon, which is operating until the 26th of September. PJ7K on St. Maarten, which is active until the 22nd of September, was worked; and VK9NT on Norfolk Island, which is operating until the 27th of September, also made it into UK logbooks. Check the DX cluster for the latest spots. Next week NOAA predicts the solar flux index will remain in the range of 125 to 135. The Kp index is forecast to remain low at 2 all week. A coronal hole threatens to push the Kp index higher, perhaps late today, the 21st, or tomorrow, the 22nd. And now the VHF and up propagation news from G3YLA and G4BAO The first part of the coming week will be under the influence of the unsettled weather pattern with lows and fronts affecting the British Isles. So, it feels like there will be a few more days for the GHz rain scatter folk to play. Be aware that even among low-pressure systems there can be fleeting moments of good Tropo. On Friday the 19th there were ideal Tropo conditions over southern Britain and south across Biscay to Spain as well as east across the North Sea. The big change takes place on Wednesday as an area of high pressure starts to build over the UK. This could last through to the end of the week. So, there is plenty of time to develop some good Tropo conditions over large parts of the UK and near-continent. There will probably be an elevated inversion some 1 or 2km above the surface. This will be caused by the high itself and may provide ducting conditions throughout the 24-hour period. This may be supported by temporary surface inversions overnight due to the ground cooling. These features tend to take a while to establish, which suggests that the latter part of the coming week may be the best time to operate. The effect will only just be starting to influence conditions over the western side of the UK for the SHF UK Activity Contest on Tuesday the 23rd. Regarding the aurora prospects, it feels like we should be keeping a watch throughout this autumn period when the Earth's magnetic field couples with the solar wind more effectively. Earlier last week the Kp reached 5, which is a good trigger to get interested in beaming north for those fluttery auroral signals. Meteor scatter remains in between events at the moment with no major showers in the period. So, it's random meteors only which, as we know, tend to favour the early morning, pre-dawn hours. We are outside the traditional Sporadic-E season now but, as you may have noticed on the Propquest graphs, there has been the occasional spike on the foEs plot up to 5MHz or so. This is plenty to generate some strong short-skip European signals on the HF bands, especially 10m. In the morning on Wednesday the 17th, Sporadic-E was probably triggered by the powerful jet stream moving east over the near continent. There may well be further occasions with strong jet streams during the next week, so keep checking the NVIS tab at propquest.co.uk to see if the foEs trace spikes again. Now for an EME update. Moon declination is decreasing, from its maximum on the 14th of September. The Moon's distance from Earth is also increasing until apogee on the 27th and 28th of September. This means path losses are growing over the next week. Sky noise will remain low until the 29th and 30th of September. And that's all from the propagation team this week.
Neste episódio do Santo Angelo Podcast, batemos um papo técnico sobre um dos temas mais desafiadores do áudio: microfones sem fio e RF (Rádio Frequência).Nosso convidado especial é André Breda, professor fundador do @educaudio , que explica de forma clara os conceitos de UHF, VHF, diversidade, interferências e como configurar seu equipamento para evitar quedas de sinal.
Explorando el Futuro: Desafíos Aéreos, Avances de la IA y la Búsqueda de Vida en MarteEn este episodio, exploraremos las últimas innovaciones y los desafíos cruciales en la aviación y el espacio. Abordaremos la colaboración pionera entre ENAIRE y NAV PORTUGAL, que impulsa rutas aéreas libres para optimizar el tráfico y reducir las emisiones de CO2, compensando el prolongado retraso en la implementación del Cielo Único Europeo. También examinaremos las urgentes deficiencias y las demandas de mejora en el Aeropuerto de El Hierro, una infraestructura vital para los habitantes de la isla, discutiendo problemas como la ineficaz gestión del parking, la persistencia del Servicio AFIS, horarios limitados y la escasez de personal, así como la oferta de mediación del Ministro Óscar Puente. Dedicaremos un segmento a la creciente influencia de la Inteligencia Artificial en la aviación, analizando sus aplicaciones en la gestión del tráfico aéreo y en las cabinas de vuelo para mejorar la eficiencia y la seguridad, al mismo tiempo que discutimos los importantes riesgos como la dependencia humana, los sesgos algorítmicos y la ciberseguridad, destacando el concepto de "Automatización Avanzada".

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 11th of September As of Thursday, the 11th of September, it looked like someone had thrown a switch on the Sun to turn off all new sunspots! Unless there is a big change, there will be no sunspots visible on the Sun's surface today, the 14th. It is clear we are no longer at solar maximum. A bigger problem is a large coronal hole on the Sun's surface, which is rotating to be Earth facing. It is on the Sun's equator, so it is ideally placed for maximum disruption to the Earth. A high-speed solar wind stream should reach Earth by the 14th of September, and geomagnetic storming may be possible at higher latitudes. Expect maximum usable frequencies, or MUFs, to drop and trans-polar paths to be affected once the Kp index rises. HF is now starting to improve as we head towards mid-September. By 1000UTC, Propquest shows that the MUF over a 3,000km path can be as high as 31MHz, as long as the Kp index stays low. This should continue to improve as we head into October. The best DX last week continued to be T30TTT in Western Kiribati, this time on the 40 and 17m bands using FT8. 9J2FI in Zambia also put in an appearance on the 17m band using FT8. TZ4AM in Mali was spotted on the 15m band using SSB. For Morse enthusiasts, HC5AI in Ecuador was working on the 15m band using CW, according to the CDXC Slack chat group. NOAA predicts that the solar flux index will start the coming week at 125 but then gradually improve to reach 145 by the end of the week. As mentioned earlier, the Kp index is set to reach 4 or 5 between the 14th and 16th of September due to the coronal hole. And now the VHF and up propagation news from G3YLA and G4BAO The present spell of unsettled weather is likely to remain the main driver of weather-related propagation modes for the next week. Low-pressure systems are following the jet stream across the Atlantic and over the UK, which is a typical track for this time of the year. This means that we should expect to experience the odd example of rain scatter for the GHz operators, and occasional strong winds will start to test that we have our antennas in good order after the quieter weather during the summer. This is not to say that there won't be any Tropo, but we will have to look for it carefully. In a mobile weather pattern such as this, the periods of high pressure tend to act as separators between the lows and, as a result, they usually move with similar speed. This makes them short-lived and thus not particularly good at establishing strong inversions for Tropo. There are two low-grade possibilities. One is around Tuesday the 16th as a weak transient ridge moves across the country. The second will be as another weak ridge moves across on Friday, the 19th. The meteor scatter situation is still pretty much in a random activity state, although there was a minor shower of the Epsilon Perseids, which peaked on the 9th and may have a few left in the tail-off. However, in general, it's more realistic to assume we're dealing with random activity. Aurora, on the other hand, has been putting in an appearance lately, so keep watching the Kp index for values climbing above 5. Now for an update on EME. Today, the 14th, marks the Moon's maximum declination – its highest point in the sky. Perigee, when the Moon is at its closest point to Earth, was passed on September the 9th, so path losses are increasing. Sky noise is low and will remain so until the 20th to 22nd, when the new Moon is very close to the Sun. And that's all from the propagation team this week.

The RSGB Convention takes place at Kents Hill Conference Centre in Milton Keynes between the 10th and 12th of October. This year marks the 70th anniversary of the RSGB's weekly news broadcast, GB2RS. The celebrations continue with three special broadcasts scheduled from the RSGB National Radio Centre, or NRC, on Sunday, the 28th of September. Three Newsreaders will broadcast GB2RS from the NRC on the 40m band, the 2m band and via the QO-100 satellite. These readings will be in addition to those in the weekly GB2RS broadcast schedule. Special event station GB70RS will be used for pre- and post-News nets. In addition, each Newsreader will start the broadcast with a special message from the RSGB President Bob Beebe, GU4YOX. Find out timings and frequencies via rsgb.org/gb70rs The RSGB has responded to a further Ofcom consultation, which would see new users sharing spectrum within the 2.3GHz amateur band. The latest proposals would enable a new class of short-notice outdoor deployments in the 2320 to 2340MHz range, for up to 14 days at a time. In its response, the RSGB has taken the opportunity to highlight strong concerns regarding the amateur weak signal segment at 2320MHz. This follows earlier Ofcom proposals last year for indoor use only in this frequency range. The response and background information can be found on the RSGB Spectrum Forum web pages. Go to rsgb.org/spectrum-forum and choose the ‘Papers and consultations' tab on the right-hand side. This month is all about amateur radio and coding for the RSGB.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 3rd of September Last week's aurora may have come as a bit of a surprise! The propagation segment for GB2RS is usually written on a Thursday, but the aurora was sparked by a solar flare that took place two days later, at 2002 UTC on the 30th of August. As we don't have a crystal ball, we couldn't have predicted it! The Kp index hit 3 late on the 1st of September, with aurora visible over much of the UK. HF propagation was affected with sudden swings in the maximum usable frequency over most of the day on Tuesday, the 2nd of September. At the time of writing, a geomagnetic storm watch remains in effect with the solar wind speed above 500 kilometres per second. September is a good month for aurora due to the Russell-McPherron effect, when the Earth's axis aligns perpendicularly to the Sun-Earth line during the equinox. This creates ideal conditions for a reconnection between the solar wind and Earth's magnetic field. So, keep an eye on solarham.com for daily updates. The Sun remains active with plenty of sunspots. The solar flux index stood at 187 on Wednesday, the 3rd, down from 202 the day before. HF propagation remains good, out of the auroral periods, and as we progress into September, it should improve even more. Some of the best DX this week included VK2/SP9FIH on Lord Howe Island using the Superfox FT8 mode, and T30TTT on Western Kiribati using both CW and FT8. Other choice DX included 3C3W in Equatorial Guinea on FT8, TJ1GD in Cameroon on 20m CW, and 5H8HZ in Tanzania on 30m FT8. Next week, NOAA predicts the solar flux index will decline to 160, and then perhaps 125. Unsettled geomagnetic conditions are forecast until the 10th, with a maximum Kp index of 4 predicted. This may be due to a large elongated coronal hole on the Sun's surface, which became Earth-facing on Wednesday, the 3rd. And now the VHF and up propagation news from G3YLA and G4BAO Rain and sequences of low pressure will drive the weather agenda for much of the coming week. The only reasonable chance of Tropo appears to be Friday and Saturday with high pressure to the southeast and support for paths to the continent and across the North Sea. It is worth noting that, in general, short-lived highs like this one do not have the necessary time to generate a strong, elevated inversion before declining. So don't expect too much. Rain scatter, on the other hand, is much more likely to be worth considering for the gigahertz stations next week, with plenty of rain events coming along. The Sporadic-E season daily blogs have now finished for this year, but you may still find it worthwhile looking at the Dourbes graph at propquest.co.uk. You will notice the odd blip on the foEs trace, so keep it in mind for the 10 and 6m bands – at least for the next week. Meteor scatter is still in random territory for this period. We are between the Perseids in mid-August and the Draconids, which peak on the 8th of October. This means that the pre-dawn morning hours will be good times to try. There were some auroral signals during the 2m UK Activity Contest on Tuesday, the 2nd. We are coming into the autumn season when conditions tend to be more favourable for aurora. The message is, of course, to monitor the Kp index for values rising above 4 or 5. Remember, these three-hourly planetary readings can smooth out shorter-duration peaks, so maybe don't wait for it to get to the dizzy heights of 6 or 7 before taking an interest. Moon declination is still negative, not going positive until Monday, the 8th. So, Moon window lengths and peak elevation will continue to increase. Path losses are still falling until perigee on Wednesday, the 10th. 144MHz sky noise is low all week. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 28th of August 2025 This week saw a change in HF propagation with a perceptible move towards more autumnal conditions. The 10 and 12m bands have started opening up to the USA, at least on FT8. As we move into September, this will improve further. Also, as we head towards the Autumnal Equinox, we can expect better conditions on north-south paths, such as the UK to South Africa. The week saw the solar flux index climb to 226 on Thursday, the 28th, thanks to a host of sunspots, mainly in the Sun's southern hemisphere. Over the last seven days, the Sun also provided us with 12 M-class solar flares. Any associated coronal mass ejections, or CMEs, were not Earth-directed, so these had little effect, and the Kp index stayed firmly at 3 or below. The latest updates suggest that there is only a ten per cent chance of a strong X-class solar flare. FT8 continues to be the preferred HF mode, or so it seems, with stations in China, Japan, Indonesia and Cameroon making their way into UK logs on the 12m band. The 10m band has also been humming with South America rolling in during late afternoon and early evening. This can only get better as we move into September and October. NOAA predicts that the coming week will start with a solar flux index of 155 tomorrow, the 1st. This may be a little pessimistic, but we'll see. It also predicts that the solar flux index will drop off as the week progresses, ending the week at 125. Geomagnetic conditions are forecast to be good for the first half of the week, but then decline from the 4th of September. Batten down the hatches as a Kp index of 6 is forecast for the 5th, with unsettled conditions lasting until the 10th of September. Check for auroral HF signals on the 5th, or even the possibility of visible aurora from the UK. We recommend you get your HF DXing in early next week! And now the VHF and up propagation news from G3YLA and G4BAO Last week saw some lovely late-season Sporadic-E on the 6 and 4m bands, including Spain, Italy, and east into Ukraine. There was an opening to Brazil on the 24th that reached as far as East Anglia, but, as usual, stations on the south coast and west of the country had the best of the transatlantic QSOs. This is the last bulletin in the nominal 2025 Sporadic-E season, which lasts from May to August. However, last week was a good reminder not to give up too soon, as there were several CW and SSB paths showing up, particularly on the 10 and 6m bands. There were also a few reports on the 4m band. The daily Sporadic-E blogs on propquest.co.uk come to an end today, the 31st, but the site will continue to provide the maps as usual. To help you, notes on how to interpret the maps are available on the website. Thanks to all the Sporadic-E operators who have submitted logs to the various clusters this year. The change over to unsettled weather is now complete, and we will see rain and thunderstorms in most areas from time to time. It's a good period to check out rain scatter propagation if you are set up for the gigahertz bands. The heavier rain is well-captured by the many online rain radar displays to help you track the most active scattering volumes, which move with the stronger winds quite high up in the atmosphere. Speeds of 30 to 60 miles per hour are common. There is one note of contrast with the model evolution after midweek. One branch sticks with low pressure to the following weekend, while another outcome tries to bring in a ridge of high pressure and a chance of Tropo propagation. If the latter turns out to be the actual evolution, it may prove useful for the 144MHz Trophy and Backpackers Contest next weekend. However, it may not have arrived in time for the 144MHz UK Activity Contest on Tuesday. The solar conditions are still providing some interest for auroral propagation, but with a Kp index less than 3, nothing of use radio-wise. Look for a Kp index increase beyond 7 for that. Meteor activity is currently between major showers, so expect random activity, which suggests early mornings for checking out meteor scatter prospects. Moon declination is negative, reaching a minimum on Monda,y the 1st. So, it's a week to check out your equipment rather than to operate. With the Sun still high in the sky, it's easy to check system performance with Sun noise. Path losses started to fall after apogee on Friday the 29th. 144MHz sky noise is close to 3,000 Kelvin on Monday, dropping back to moderate on Wednesday. And that's all from the propagation team this week.

Allen Hall: Welcome to the Uptime Wind Energy Podcast. Hold on tight. I told my producer before we started, this is gonna be a. Bumpy rise. So for all our listeners, hold on. Uh, it's a lot of news in the wind and solar world at the minute. Phil Tarro is in California. Joel Saxon is back from Australia in Austin, Texas, and first up is the Federal Department of Transportation. Complaining about how close wind turbines could be to railroads and create an interference, and it'd be a safety crisis. Uh, federal transportation officials and a new scientific research report, [00:01:00] Joel, are sounding an urgent alarm about wind turbines being. Too close to railroad tracks and a comprehensive study from California's Tehachapi Pass Wind Farm confirms, quote unquote confirms that wind farms can severely interfere with critical radio communications used by trains. Now, uh, what they don't want you to do is to read the report. That's what they don't want you to do. And, uh, as a group of engineers, we're going to read the report and see what it says. And what it says is that they have a safety system on trains because they used to run into each other quite often. And what they've done is they have a overriding system that's run by radio communication that if a train goes too fast and some of these more frequented train tracks or in. High density population bases like Chicago or Baltimore, one of these places that they can actually slow the train down or stop the train in some cases, what it sounds like if they're [00:02:00] on a collision course, and that becomes important on commuter rails. And, um, if they have toxic chemicals on trains, that they don't want them to have accidents. So they put the system in. And the system is based on Joel. The world's oldest communication form. Joel Saxum: It's VHF radio, right? So to those of you that don't know what VHF radio is, it's basically like, uh, close to the frequencies you'd use as a walkie-talkie as a kid. Um hmm. Right. Uh, or a CB radio. Right. We're, we're quite a ways past that now. Uh, so wifi, cell modems, satellite communications are all regular things within basically any other industry. Uh, of course, but this one, yeah, we're still using VHF technology that we used. I, that's been around for a long time for radio communication back from World War ii. Or before that? Oh yeah. Allen Hall: Right around World War ii. How far do those, uh, walkie-talkie radios typically Joel Saxum: work? Well, it depends if you, I guess if it depends if you buy 'em from Walmart or if you buy 'em a, [00:03:00] a, a professional one. But, uh, depending on what watt radio is in 'em, I mean mile two miles maybe. Allen Hall: Exactly. And that's how this train system works. So every. Couple of miles, they have a repeater to transmit the signal up and down the train tracks. Well, it became really important because, you know,

Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. On Tuesday the 26th, the RSGB SHF UK Activity Contest runs from 1830 to 2130UTC. Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator. The World Wide Digi DX Contest starts at 1200UTC on Saturday the 30th and ends at 1200UTC on Sunday the 31st of August. Using FT4 and FT8 on the 160 to 10m bands, where contests are permitted, the exchange is your four-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 21st of August Last week was relatively good from an HF propagation standpoint, with only a few periods with an elevated Kp index thanks to a high-speed solar wind stream from a coronal hole. The Kp index hit 4.67 on the 19th of August and 4 again on the 20th due to the solar wind hitting earth at more than 600 kilometres per second. Luckily, the interplanetary magnetic field remained mostly neutral, or north-facing, and the density was low, saving us from more disruption. Meanwhile, the solar flux index declined to 120 by Thursday the 21st. This is still high enough to affect the ionosphere, but well down on recent highs in the 140s and 150s. The daytime critical frequency has mostly remained above 7.5MHz, meaning the 40m band has managed to remain good for inter-UK contacts. This has also meant that maximum usable frequencies, or MUFs, over a 3,000km path hit 21MHz and even 24.9MHz at times. Nighttime critical frequencies have been around 5MHz, giving an MUF over 3,000km of below 14MHz and sometimes even as low as 10MHz. It may be another month or so before we see daytime F2-layer openings starting again on 28MHz. In the meantime, focus your efforts during daylight on 21MHz and below. T30TTT in Western Kiribati remains one of the DX stations to chase, mostly on 18 and 21MHz. The operators are alternating between using CW, SSB and FT8. Other choice DX worked included Jim, E51JD on South Cook Islands who has been active on the 17m band using SSB. TY5AD in Benin, Africa has been worked on the 10m band using FT8. And 3G1P, an IOTA DXpedition in Chile, was logged on the 15m band using SSB. Closer to home, today, the 24th, is the last chance to work OG0C on the Aland Islands. Next week, NOAA predicts that the solar flux index will remain in the 120s, until the end of the month when it could rise to 130 and even 150. Unsettled geomagnetic conditions are forecast for the 28th of August when the Kp index could hit 4. Otherwise, make the most of the relatively settled conditions over the first half of next week to work some choice DX! And now the VHF and up propagation news from G3YLA and G4BAO After this weekend, the weather changes from a Tropo high pressure pattern to an unsettled story with areas of low pressure and fronts together with wind and rain. This will remove any Tropo options and replace them with a possibility of rain scatter on the GHz bands. The auroral conditions have recently produced minor enhancements, although nothing too exciting so far radio-wise. It's worth noting that the autumn, along with spring, are times of the year when auroras are more likely. So, it's a good time of the year to keep abreast of the Kp index, especially if the Kp index goes above 5. We are at the tail end of the broader period of the Perseid meteor shower, ending today, the 24th. This leaves random meteor activity as the only option for a while. As those of you who are active in the mode already know, it tends to favour the early pre-dawn period for better chances of catching meteor scatter. Sporadic-E is hanging on for the last week or two of the 2025 season, but opportunities become much rarer. You'll need to keep a close watch on band reports to capture these increasingly fleeting events. In the main Sporadic-E season, there are usually two well-defined peaks of activity in the morning and late afternoon. However, in the tail of the Sporadic-E season you are just as likely to find it around the middle of the day as at any other time. The daily Sporadic-E blogs at propquest.co.uk finish at the end of August, but in some years the last events have extended into the first week of September. Moon declination is still positive, but falling, going negative on Monday. So, Moon window lengths and peak elevation will follow suit. Path losses are rising again as we approach apogee on Friday the 29th. 144MHz sky noise was low until lunchtime on Friday the 22nd, when the Sun and the Moon were very close in the sky. This continued throughout the Moon window on yesterday, the 23rd, and will revert to moderate-to-low next week. And that's all from the propagation team this week.

The Convention takes place between the 10th and 12th of October and is a must-do on every radio amateur's calendar. The RSGB Awards Manager has introduced a new awards series for amateur radio contacts with stations across all UK country and Crown Dependency prefixes. The Worked All UK and Crown Dependency Prefixes Award offers several different sub-sets, with the rules varying slightly for each. The idea for the award was put forward as a way of encouraging, or tapping into, intra-UK activity as well as encouraging contact with UK amateurs. Get involved with this new award by going to rsgb.org/awards and selecting ‘Worked All UK and Crown Dependency' from the right-hand menu. You can find details of other awards offered by the Society using the same link. National Coding Week takes place during the third week of September, and the RSGB is dedicating the whole of the month to amateur radio and coding activities. This year, the Society has created two new activities for you to try. Both build on worksheets it shared in previous years; however, you don't have to have done those first. The Python Pocket Morse activity has been developed by the RSGB Maker Champion Tom Wardill, 2E0JJI and is a low-cost opportunity to learn some Morse and programming together. The exercise will cover using a BBC Micro:bit V2 and the ‘more advanced' Python programming instead of the previous block programming mode. It is intended as a gentle introduction to both Python and small computer programming and can be done without any previous knowledge of the micro:bit. You can download the full instructions by going to rsgb.org/coding and selecting ‘Python Pocket Morse' from the right-hand menu. The other new activity is the LoRa balloon challenge. As well as the manual, which guides you through the process of building your own LoRa tracker and seeing how far your signal can reach, the Society has released a video in which Fraser, MM0EFI, demonstrates the process. Find both on the RSGB website at rsgb.org/lora-balloon International Lighthouse and Lightship Weekend started at 0001UTC on Saturday, the 16th and ends at 2400UTC today, the 17th of August.

Now the contest news On Tuesday the 19th, the RSGB 1.3GHz UK Activity Contest runs from 1900 to 2130 UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator. On Thursday the 21st, the 70MHz UK Activity Contest runs from 1900 to 2130 UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. On Sunday the 24th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800 UTC. 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 14th of August Last weekend was characterised by unsettled geomagnetic conditions caused by a massive coronal hole on the Sun. At one point, the Kp index got up to 6, with a corresponding decrease in maximum usable frequencies, or MUFs. The Dourbes Digisonde failed to record much at all over six hours. Luckily, that disruption had passed by Monday the 11th as the ionosphere started to get back to normal. Meanwhile, the solar flux index reached a peak of 153 on the 10th, before dropping back to 140 on Thursday, the 14th. There have been numerous C-class solar flares and ten M-class events over the past five days, but nothing of note. The MUF over a 3,000km path exceeded 24.9MHz at times, but has generally been between 21 and 24MHz. Another coronal hole is Earth-centric at the moment and could cause some disruption, with increased Kp indices by tomorrow, the 18th or Tuesday the 19th. HF DX has been good at times, with the stand-out station being T30TTT in Western Kiribati. The station has been worked on many bands, including 20, 15 and 10m using CW, as well as FT4 and FT8. After two weeks, there will be just one operator who is there until mid-September. So you have plenty of time to work him. Stanley, AH6KO, in Hawaii, has also been spotted on the 15m band using CW. This is a relatively rare opportunity and good for anyone chasing their Worked All States award. A little closer to home is Henri, OJ0JR on Market Reef, who has been easily workable on the 30m band using FT8. Get in quick, though, as he is only there until tomorrow, the 18th. Next week, NOAA predicts that the solar flux index will remain in the 140 to 150 range. Unsettled geomagnetic conditions are forecast for tomorrow, the 18th, until Wednesday the 20th, probably caused by the coronal hole mentioned earlier. Better conditions are predicted for the 23rd to the 27th with a maximum Kp index of 3. And now the VHF and up propagation news from G3YLA and G4BAO Last week's propagation highlights were SSB and CW QSOs between the UK and Las Canarias on both the 23 and 13cm bands between G4GLT, EA8DMF, ED8BRZ and EB8AYA. There may be more Tropo next week with high pressure close to, or over, the British Isles. However, at this time of the year, any Tropo will be due to temperature inversions. These can be at the surface and are especially persistent over water, so look for marine paths across the North Sea or up the east coast to Scotland. Other potentially good marine paths might be across the Channel or Biscay to Spain and beyond. The hot days of high summer break down these surface inversions over the land during the day so, if your station is inland, your best chances of Tropo in summer will often be overnight and until mid-morning. Inversions can also be elevated in the region of the high pressure, say between 1 and 2km above ground, giving good DX prospects that are not affected by the heating of the summer day. In this high-pressure period, it is much more likely to be a surface inversion that drives the Tropo. There will be little rain in prospect except for parts of Ireland, South Wales and southwest England, where a few thundery showers are possible. However, these will not be particularly good for rain scatter. There continue to be some aurora alerts, so monitor the Kp index and if it is rising to, say, 6, try beaming north on the 10, 6, 4 and 2m bands in turn to see if any genuine auroral signals are coming back. Lastly, the Sporadic-E season is coming into its closing weeks. 10m is a good band to check first. If Sporadic-E is very short-skip there, try moving up to 6m or beyond for a strong event. Digital modes are best, so use these to get clues as to where the CW and SSB paths might show up next. Meteor scatter operators have been very busy during the Perseids meteor shower. The Perseids should still provide some activity in the coming week. Moon declination is positive and rising until Tuesday the 19th, so Moon window lengths and peak elevation will follow suit. Path losses are rising again as we are now past perigee. 144MHz sky noise is low to moderate all next week. And that's all from the propagation team this week.

Using FT8 on the 70cm band, the exchange is a report and a four-character locator. Stations entering the four-hour contest may also enter the two-hour contest. On Thursday, the 14th, the RSGB 50MHz UK Activity Contest runs from 1900 to 2130 UTC. Using all modes on the 6m band, the exchange is a report and four-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 7th of August Over the last week, we had nearly ideal solar conditions for HF propagation. These included low geomagnetic indices and a reasonable solar flux index, hovering around the 150 mark. Other solar events of note included six M-class solar flares. The only stumbling block is the time of year, with summer seeing lower maximum usable frequencies, or MUFs, and poorer propagation due to changes in ionospheric chemistry. We will have to wait another month or so to see conditions pick up. The main HF DX this week has been T30TTT from Western Kiribati, mainly on FT8 and CW and focusing on the 20 and 17m bands. TJ1GD from Cameroon was worked on the 17m band using FT8. E51KEE on the South Cook Islands was logged on the 17 and 15m bands using CW. And finally, AH6KO in Hawaii was worked on the 15m band using CW. But this may all be set to change. A coronal mass ejection observed on Tuesday, the 5th, may deliver a glancing blow to the Earth's geomagnetic field. This may also coincide with an expected high-speed stream from a very large coronal hole on the Sun's surface. NOAA predicts that the Kp index could rise to 5 or 6. The hole is so large and elongated that we could see unsettled conditions occurring in the coming week. NOAA predicts unsettled geomagnetic conditions from the 11th to the 14th of August. It also predicts more unsettled conditions from the 18th to the 22nd, with a maximum Kp index of 5. Expect reduced MUFs and poor HF conditions, especially for paths over the poles. And now the VHF and up propagation news from G3YLA and G4BAO The main setting for the weather pattern over the next week is a tendency for high pressure in the south and lower pressure to the north of Britain. There may be some input from a low over France around the middle of the week. This might introduce some thundery showers and a chance of rain scatter on the GHz bands. Meanwhile, occasional weak frontal systems will bring patchy rain to the far northwest, but probably not so good for rain scatter opportunities. The Tropo at this time of year can be very good around the coasts and occasionally inland overnight. However, it tends to weaken inland during the heating of the day. Out at sea, temperatures remain fairly constant and maintain an ideal cool, moist layer at the sea surface overlain by a layer of warm, dry air from the land. This provides Tropo 24 hours a day, seven days a week. Mid-August is good for meteor scatter with the peak of the Perseids on the Tuesday night of the 12th and 13th. Apart from digital-mode QSOs, it's good for late summer evening sky watching. It is fascinating to listen to the VHF SSB meteor scatter frequencies while watching to get the full experience. It's a broad shower, so don't worry if you must pick a night either side of the peak. The chances of an aurora are not zero, with further minor alerts to remind us that it's worth checking. The main mode for DX is probably still going to be Sporadic-E, which has roughly another four weeks to run. Don't expect something every day, as it tends to become more random towards the latter part of the season. Moon declination is negative, but rising again, so Moon window lengths and peak elevation will increase. Path losses are also falling, reaching a minimum at perigee on Thursday, the 14th of August. 144MHz sky noise is low to moderate all next week. And that's all from the propagation team this week.

The Worked All Europe DX CW Contest starts at 0000UTC on Saturday, the 9th and ends at 2359UTC on Sunday, the 10th of August. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 31st of July 2025 Last week was very much a repeat performance of the week before. We had relatively calm geomagnetic conditions and few solar flares to contend with. The only flares were minor C-class events. The Kp index never got above 3, and the solar flux index was in the 140s to 150s. The F2-layer maximum usable frequency over a 3,000km path rose to 21MHz but didn't get much higher, which is normal for the summer period. A team from Norfolk Amateur Radio Club was active as GM0FRT/P from the Shetland Islands for the IOTA contest. They were workable from JO02NN on 14 and 21MHz for much of the contest period. The distance to Shetland from central UK is about 887km, or 551 miles. Given the distance involved, the 21MHz openings were probably Sporadic-E, but they were loud for hours on end. Other DX worked last week included T30TTT from Western Kiribati on the 10m band using FT8 over the North Pole. 9M8A from East Malaysia was also on the 10m band using FT8. XW4KV from Laos was on the 12m band operating FT8. 3B9SP on Rodriguez Island put in an appearance on the 17 and 12m bands using FT8. The station was also worked using CW on the 40, 30, 20 and 15m bands. That's not a bad haul for summer DX and if the Kp index can stay low, we could get similar next week. Speaking of which, NOAA predicts that the solar flux index will be in the range of 150 to 160 next week. Unsettled geomagnetic conditions are forecast for the period of the 7th to the 14th of August, with a maximum predicted Kp index of 5. And finally, there is talk of a possible large sunspot group on the far side of the Sun. The region in question belongs to a cluster of spots, including AR 4136, 4139 and 4143, last seen earlier this month. Solar rotation will carry what remains of these regions back into view next week. So, keep an eye on solarham.com for up-to-date details. And now the VHF and up propagation news from G3YLA and G4BAO The slightly unsettled theme to the weather will remain into next week, although there are signs that high pressure will try to return in the middle of the week for a time. Models disagree on details, with some bringing another thundery low into the south later. This means that there will be some Tropo at times and, in high summer, this tends to be generally strongest around the coasts. To benefit from these conditions inland it's better to wait for night cooling. As usual with thundery weather, it's a good chance to listen for rain scatter on the GHz bands. Another mode that still deserves attention is meteor scatter. Look out for the early stirrings of the August Perseids, which peak around the 12th and 13th of the month. Surprisingly, Aurora is staying in the limelight. Periodic alerts are suggesting it's worth turning your VHF beams north if you notice any signs of fluttery HF signals or discover the Kp index has risen to 5 or above. If auroral activity appears on the 10 or 6m bands, then check the higher bands as the event develops. Sporadic-E is now in its occasional phase as we move into August. It is less common than in June, but still worth considering. Check the usual cluster maps and Propquest to see how the day is unfolding. Moon declination is negative, falling to a minimum on Tuesday, the 5th. So, Moon windows and peak elevation will also decline. Path losses reached maximum at apogee on the 1st of August, so are starting to fall again. 144MHz sky noise starts the coming week moderately, but will rise to high levels by Monday. It will reach over 300 Kelvin by Tuesday evening before falling back. And that's all from the propagation team this week.
In Episode 2 of the Prep Comms MURS Mini-Series, Caleb Nelson dives deep into what really determines your performance on MURS. Spoiler: it's not power. It's your antenna, your coax, your terrain—and how well you understand what you're working with. This isn't theory. These are real-world setups from real users—from the hills of Pennsylvania to the silence of Utah. You'll learn exactly what works and why, including gear recommendations that Caleb personally uses on his family farm and in mobile scenarios. Topics Covered: Real listener feedback on MURS performance The truth about 2 watts and how far it can really go VHF vs. UHF performance in rural terrain Coax cable explained (RG8X vs LMR-400) Legal antenna height and why it matters Why MURS is not private—and why that's still okay Mentioned in this Episode:
This is the VIC 4 VETS, Weekly Honored Veteran. William “Bill” Sabastian Salfen SUBMITTED BY: A regular listener _____________________________________________________________ Hi Vic and Ken! I hope this veteran will fit nicely into you and Vic's wonderful daily/soon-to-be-weekly tribute to veterans. I hope you can offer some acknowledgement of a local hometown hero from the past. As I stated before, I neither need nor desire recognition for offering his story - if you use it, can you just say a regular listener brought him to your attention? I worked in Bridgeton, Mo for 16 years, which was where I met Bill Salfen. He was a close, longtime friend of the business owner, and was around quite frequently in all of my years working there, dying the same year I left the business in 2014. Bill showed me multiple official documents regarding his service time, his capture and imprisonment, and eventual release. I have no reason to question his words. I spoke with Bill often about his WWII escapades as a B-24 Bomber Pilot who was shot down and captured by Nazis, then imprisoned at Stalag 1 as a POW. There are a couple different articles I've found stating his age (either 20 or 21) at capture, but Bill personally told me he was 20 when he was shot down - according to him (as well as other sources I've seen over the years) he was the youngest bomber pilot (NOT Co-Pilot) in the US Army Air Forces at the time. Regardless...he was just out of his teens, and Captaining (piloting) a US B-24 Bomber against an enemy force! After his war experiences, Bill became very active in Food Search type programs, and had a specially insulated van he would collect groceries in to distribute to the homeless, and to the food banks in the St. Louis area. In his own words, he told me that he did so because during his time in captivity, he found out all about real hunger, and knew firsthand the pain experienced from it. Bill told me that he had wires holding his jaw together from a German soldier "knocking his face loose" with the buttstock of a rifle during his capture, and true to his nature (as I knew him, anyway) he also said that he didn't blame the German soldier; "after all I (we, the US) was killing Germans and their families." Bill had visible scars all over both arms from German Shepard attacks he sustained during both his initial capture and his multiple escape attempts from Stalag 1. He told me he tried 3 times to escape, and was recaptured each time. The tip of one of his fingers was missing up to past the nail where, he told me, they put it in a bench vise and tortured him by squeezing it, then releasing it, then squeezing the damaged fingertip again the next day and the next, until, as he told me, he finally talked and they pinched the damaged fingertip completely off. He was unashamed about talking, and he had nothing to be ashamed of, in my opinion. I feel very honored to have met and known for years this man that I personally consider to be a true American Hero from WWII. He is a 69 year Founding member and first Captain of VFW POST 5077, O'Fallon MO, a 33 year volunteer at Operation Food Search St. Louis MO and St. Mary's Parish Bridgeton, MO, retired Teamster, union negotiator and 17 year subject of Wash U Memory and Aging Study.

We had just closed the bomb bay doors after releasing bombs over Kassel when our plane took two bursts of flak. One hit the left wing and the other went into the tail section. The hit in the wing took out the #1 and #2 engines, so that made it impossible to keep a heading without complete cross control of ailerons and rudders. Needless to say, loss of altitude was very rapid. We rode it down to 1,500 feet, at which time we bailed out and soon were captured. After Salfen and I bailed out, the aircraft entered a flat spin, crashed and burned. We were told that Robert Doherty's parachute failed to open and the seven-surviving crew of nine were captured by the Nazis.” William Salfen had been missing in action since 7-October 1944 and was a prisoner of war for 188 days. The St. Charles Weekly Banner reported on 24-May 1945, William Salfen in Stalag Luft 1 was liberated by the Russians.

This is the VIC 4 VETS, Weekly Honored Veteran. William “Bill” Sabastian Salfen SUBMITTED BY: A regular listener _____________________________________________________________ Hi Vic and Ken! I hope this veteran will fit nicely into you and Vic's wonderful daily/soon-to-be-weekly tribute to veterans. I hope you can offer some acknowledgement of a local hometown hero from the past. As I stated before, I neither need nor desire recognition for offering his story - if you use it, can you just say a regular listener brought him to your attention? I worked in Bridgeton, Mo for 16 years, which was where I met Bill Salfen. He was a close, longtime friend of the business owner, and was around quite frequently in all of my years working there, dying the same year I left the business in 2014. Bill showed me multiple official documents regarding his service time, his capture and imprisonment, and eventual release. I have no reason to question his words. I spoke with Bill often about his WWII escapades as a B-24 Bomber Pilot who was shot down and captured by Nazis, then imprisoned at Stalag 1 as a POW. There are a couple different articles I've found stating his age (either 20 or 21) at capture, but Bill personally told me he was 20 when he was shot down - according to him (as well as other sources I've seen over the years) he was the youngest bomber pilot (NOT Co-Pilot) in the US Army Air Forces at the time. Regardless...he was just out of his teens, and Captaining (piloting) a US B-24 Bomber against an enemy force! After his war experiences, Bill became very active in Food Search type programs, and had a specially insulated van he would collect groceries in to distribute to the homeless, and to the food banks in the St. Louis area. In his own words, he told me that he did so because during his time in captivity, he found out all about real hunger, and knew firsthand the pain experienced from it. Bill told me that he had wires holding his jaw together from a German soldier "knocking his face loose" with the buttstock of a rifle during his capture, and true to his nature (as I knew him, anyway) he also said that he didn't blame the German soldier; "after all I (we, the US) was killing Germans and their families." Bill had visible scars all over both arms from German Shepard attacks he sustained during both his initial capture and his multiple escape attempts from Stalag 1. He told me he tried 3 times to escape, and was recaptured each time. The tip of one of his fingers was missing up to past the nail where, he told me, they put it in a bench vise and tortured him by squeezing it, then releasing it, then squeezing the damaged fingertip again the next day and the next, until, as he told me, he finally talked and they pinched the damaged fingertip completely off.

GB2RS News Sunday the 27th of July The news headlines: RSGB confirms more speakers for its Convention in October Get involved with the RSGB LoRa high-altitude balloon challenge The RSGB releases a high-contrast logbook to improve accessibility The RSGB has shared details of more presentations that you can enjoy at its Convention in October. If you'd like to broaden your technical knowledge, you'll enjoy presentations by Bob Burns, G3OUU, on ‘Getting the most from an oscilloscope' and ‘Ladder crystal filter design'. As part of the Society's focus on supporting modern amateur radio operating practices, Paul Galwas, M0WLG, will be discussing ‘Can we ‘DX' over an IoT mesh?'. The comprehensive programme of speakers also includes Dr Marcus Walden, G0IJZ, who will explain the numerical modelling of the historical Grimeton VLF antenna, and Paul Beaumont, G7VAK, who will take ‘A brief look at Number Stations: 1950 to the present'. With even more captivating and thought-provoking speakers already confirmed, you'll need to purchase a ticket to guarantee attendance. Buy your tickets before Monday, the 11th of August, to ensure you receive early-bird ticket pricing. Tickets are available to purchase via rsgb.org/convention National Coding Week takes place in the third week of September, and the RSGB is once again dedicating a whole month to amateur radio and coding activities. As part of the Society's strategy to encourage practical skills development, it is inviting you to take part in its LoRa high-altitude balloon challenge. The project has been developed by the RSGB Outreach team and takes place on Saturday, the 20th of September. The balloon will be equipped with a LoRa digipeater, and your challenge is to follow the instructions provided and build a LoRa tracker. If your tracker build is successful, it will beam up packets to the airborne relay, which will transmit them to a local i-gate. Your goal is to get your signal the furthest distance from the launch. Anyone can enter, but to win one of the prizes, you need to be an RSGB member. Get involved as a single operator or as a team in your RSGB-affiliated club. The RSGB is delighted that Moonraker is sponsoring this event and will award a £200 Moonraker voucher to the winner of each category. Find out how to get involved with this exciting LoRa event by going to rsgb.org/lora-balloon The RSGB is proud to announce the release of a new high-contrast logbook designed to support amateur radio operators with visual impairments or learning difficulties. Responding to feedback from members and accessibility advocates, the RSGB developed the logbook with wider spacing and a high-contrast black-and-yellow design to improve ease of use. This release reflects the RSGB's wider commitment to improving accessibility across all areas of the Society and amateur radio as a whole. The organisation continues to explore ways to make the hobby more inclusive and user-friendly for all participants. This version will be available through Amazon and is expected to be a useful addition for both seasoned operators and newcomers looking for a more accessible logging option. As part of its long-term vision, the RSGB is looking to recruit a dedicated team to assess and enhance accessibility throughout the Society and help shape a more inclusive future for amateur radio. If you're interested in contributing to this important initiative, please email RSGB Board Director Nathan Nuttall, 2M0OCC, via 2m0occ@rsgb.org.uk Since the launch of its DMR project in May, the RSGB Outreach team is delighted that four schools and one homeschool have signed up. The project aims to help young people get on the air and build their confidence in making QSOs. Each of the successful applicants will be loaned a TYT DMR handheld radio and a Pi-Star-based hotspot. The RSGB Youth Chair and Youth Champion for Schools, Chris Aitken, MM0WIC, is supporting two new school amateur radio clubs that have chosen this as an entry-level activity for their club members. DMR is particularly useful in a school club scenario where antenna placement is a challenge and can be easily deployed, giving young people access to the world. During the summer holidays, the DMR handsets will be used at the West Sussex International Jamboree with Regional Representative 10, Simon Harris, G4WQG, attending the event and Wick High School Radio Club member Jacob, MM7IFL, supporting remotely via DMR. Listen out for further updates after the summer when the RSGB plans to get a youth net operational on Brandmeister Talk Group 23554. The net aims to encourage young operators to get on the air and become comfortable with QSO structure and general rag-chewing. If you want to start a school club or are interested in being part of the DMR project, email Chris via youthchampion.school@rsgb.org.uk The prospect of a USA constellation of 240 commercial satellites that would use 430 to 440MHz for wideband control and telemetry has prompted an unprecedented response from the amateur radio community to a Federal Communications Commission, or FCC, consultation. FCC Proceeding 25-201 would see AST SpaceMobile utilise much of 430 to 440MHz for downlinks, as well as a series of ground stations around the world. The RSGB and several other IARU member societies, along with the ARRL and over 2,000 individuals, have submitted comments to this consultation. The IARU itself has also issued a statement on the matter. Links for this, including the RSGB response, can be found on the RSGB website. Go to rsgb.org/spectrumforum and then choose the ‘Papers and consultations' option in the right-hand menu. Following the main submission deadline of the 21st of July, the FCC process has further phases to go through. Amateur radio operators are invited to take part in a special operating event in August, celebrating the rich history of the UK's wartime and Cold War airfield bunkers.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 24th of July It was a bit of a mixed bag last week. The first half saw settled geomagnetic conditions, but from the 22nd of July, we had a disturbance thanks to output from a solar coronal hole. This saw the Kp index rise to 4.67 and ultimately 5. The stream from the Sun reached around 730 kilometres per second, while the Bz component of the interplanetary magnetic field, or IMF, was mostly neutral with a few brief periods when it pointed slightly south. So, its effects were perhaps not as bad as they could have been. The coronal hole has now rotated out of view, so we may have some better days. Meanwhile, the solar flux index has been in the range of 140 to 150, which is pretty good. There were no M-class or higher solar flares over the past week, which is unusual. So overall, HF propagation was humming, at least until the Kp index hit 5. Maximum useable frequencies, or MUFs, over a 3,000km path during daylight continue to be around 21MHz, but often dip to 18MHz at times. Nighttime conditions can be variable. If the 14MHz band isn't open for you, try 10MHz. Earlier in the week, some daytime tests with WSPR on the 20m band saw stations logged from Australia and the far west of Canada. DP0POL, the Polarstern research vessel doing work in the Artic, was also logged. Next week, NOAA predicts that the solar flux index may decline slightly to be in the range of 130 to 135. Geomagnetic conditions are predicted to be settled until the 1st of August, when the Kp index could rise to 4. This period of unsettled conditions, with reduced MUFs, could last until the 4th of August. And now the VHF and up propagation news from G3YLA and G4BAO We will see the return of a weak ridge of high pressure today. This will last until the middle of the coming week. The second half of the week will be a little more unsettled with some occasional spells of rain. This suggests that some Tropo is possible, before a gradual swap over to rain scatter. However, high pressure near the Azores may still influence the western side of Britain. This week will see the peak of two meteor showers, the Alpha Capricornids and Delta Aquariids. These are worth checking out, if only to get your practice time in before one of the major showers of the year – the Perseids on the 12th and 13th of August. Barely a day passes without some auroral alert, and this can be an exciting mode. Several good indicators are available, such as when the Kp index is above 5, or watery-sounding signals on the 40 and 20m bands. If you hear these, try looking north on the 6, 4 or 2m bands. Sporadic-E continues to be mentioned on the clusters somewhere in Europe on most days. But remember that it's a very localised mode and is rarely available for everyone at the same time. The best way to track it down is to use the clusters and a good list of beacons, to see who your ‘locals' are working on FT8. It's a very hit-and-miss mode. Meteor activity is a good indicator, whereas a high Kp index is a bad one. Whether it happens is often a balance between many opposing components. So, even a potentially good day may not be good where you are. The good news is that the last openings of the summer can occur into the first week of September. Moon declination is still positive but going negative again on Tuesday, the 29th. Moon windows and peak elevation will reduce. Path losses are rising now as we are past perigee. 144MHz sky noise starts the coming week low but will rise to moderate by the weekend. And that's all from the propagation team this week.
Most people don't even know what MURS is—and that's exactly why it works so well. In this first episode of the Prep Comms MURS Mini-Series, Caleb breaks down the quiet power of the Multi-Use Radio Service: a license-free, analog-only VHF service with just five channels and a lot of practical potential. You'll learn about its roots in the old business band, what the “Color Dot” frequencies mean, why MURS is legal without a license, and how it fits into a low-key family comms plan. Privacy, power limits, antenna rules, and gear you can actually use—it's all covered here. Listen in, and discover why MURS might be the perfect base layer in your emergency communications setup. In this episode: The FCC origin of MURS and its roots in the Business Band (DOT and STAR channels) What MURS can and can't do legally (no digital, no repeaters) Antenna height limits and the truth about privacy tones How MURS works around barns, homes, driveways, and family outings Why VHF still outperforms UHF in open terrain My own family's use of MURS as part of the Cascade Protocol Mentioned in this episode: Free MURS + Business Band Frequency Guide PDF: MURS Frequency PDF Recommended MURS radios & antennas (Caleb's gear list): Caleb's Amazon Store: Search MURS Want to go deeper?

Foundations of Amateur Radio In the community of radio amateurs scattered around the planet we have a habit of getting together with others to have fun in whatever shape that takes. The obvious ones are HAMfests, car boot sales, raffles and other amateur adjacent pursuits, but we also do things like licence training, weekly on-air nets, contesting, portable activations, climbing mountains, or hills, setting-up in parks, or lighthouses, we set-up on a field day, just for fun, and find excuses, sorry, reasons, for any number of other activities. Some of these are solitary affairs, but many are best enjoyed shared with multiple friends, both old and new ones. Having been a member of this community since 2010 I've come to observe an aspect of this community that is odd, to say the least. We organise all these events, but rarely promote it beyond a single email to three people, if that. It's almost as-if the average organiser thinks that their event permeates the community by magic osmosis. Even if there is any form of promotion, there's sometimes a date and time, but hardly ever does it show that time in UTC, even if it's a radio event, it's like we've forgotten that radio waves pass through time zones, or there is a misconception that everyone on the planet knows what your local timezone is, let alone if it's summer or winter time at the time of the event. So, what does promoting your event look like if you actually want people to know about it? For starters, you should consider who you want to have as a participant. A local HAMfest is unlikely to attract people from around the globe, but Friedrichshafen and Dayton are examples that contradict that notion. A VHF-only event might be intended for local amateurs, but what if it allows for satellite or digital contacts, like say via Allstar, IRLP or Echolink? Similarly, you might run a weekly on-air net, but have visitors from around the planet. The point being, that your audience might not be exactly what you initially think. In other words, there might be people playing from further afield. Consider that when you announce what time the event starts, and finishes. Speaking of finishing, adding an expected closing time is helpful for participants where only one member of the family lives and breathes amateur radio and the rest just want to get on with their respective lives, so consideration is welcome. Aside from telling your audience when and for how long the event goes, adding a location is not optional. You'd be surprised how many events say things like: "it's again in the usual location", or "we're at the community hall" without ever publishing an address. I can tell you, it's fun discovering that the name of the hall isn't unique. Now, for the big one. After putting the information together about the event itself, where and how do you announce it? For starters, on your own website, in whatever form that takes. It serves two purposes, announcing to the world what is happening, but it's also the definitive place where the right information is published. This is important because things change, get cancelled, moved, updated, whatever. Life isn't static, so you need to define a place where the official announcement lives. At this point I'd like to mention that this is often where promotion stops. It's easy to think that in your universe everyone you know is aware of your website, but that's just not true. A single place to publish is not the end of the process, it's the start. Then you need to use things like the local news broadcast, the national news broadcast, the international news broadcasts, contesting websites and calendars, social media, fediverse and whatever else you can get your hands on. You need to include it in your own club news, in club newsletters from other clubs, on the local amateur notice board, you need to talk about the event on-air, share it during on-air nets and if it's recurring, tell the world that it's going to happen again next year. Nothing here is revolutionary, it's not like launching a rocket into space, this is basic common sense and you too can do this. If you need help, ask. So, if you have an event that you want to have participants for, you need to make noise. Publishing the announcement at the local planning department in Alpha Centauri 50 years before the event is going to cause issues, as will defining the date for an annual event as: When the June solstice is on a weekday (Monday through Friday), the weekend following shall be the weekend of the event. When the June solstice falls on a Saturday or Sunday, that weekend shall be the weekend of the event, but only for the Winter field day, the Summer one requires you to count back four weekends, or forward, depending on if you're talking about the Spring or Summer event, and add one if it falls on the weekend. In case you're wondering. No, I didn't make that up. It's real. I'll leave you to ponder how you'd add such an event to your family calendar. I'm Onno VK6FLAB

To read about the awards and wider celebrations that are taking place for the 70th anniversary of GB2RS, go to rsgb.org/gb70rs RSGB Board Director, Ben Lloyd, GW4BML, has appointed Ian Stevenson, G3YNU, as the volunteer RSGB STEM Champion. This new role fits with the RSGB's strategy to bring amateur radio to new audiences and to highlight the link between amateur radio and science, technology, engineering and maths. Ian brings a wealth of experience to this role, having been a mathematics teacher for ten years, with a further 23 years in Higher Education as a Senior Lecturer in ICT and Education. Ian also played a pivotal role in establishing the RSGB School Links Project, which introduced classroom activities that connect amateur radio with the school curricula. The project was established following Tim Peake's Principia mission to the International Space Station, which included ten UK ARISS school contacts during Tim's time in space. In his new RSGB role, Ian is enthusiastic about fostering close ties with STEM organisations and STEM ambassadors across the UK, including those already engaged with the RSGB. If you'd like to contact Ian to share suggestions that may enhance the RSGB's STEM outreach programme, you can contact him via stem.champion@rsgb.org.uk If you are looking for an activity to keep the children busy during the summer holidays, why not plan a visit to the RSGB National Radio Centre at Bletchley Park? The knowledgeable and welcoming volunteers will be on hand to give an introduction to radio technology, how it works and why it is still relevant today. There are interactive displays as well as the opportunity to get a certificate for sending your name in Morse code. There will also be three more of the successful Spy Transmitter events during the summer, so keep an eye on the Bletchley Park website and the RSGB comms channels if you'd like to take part. Start planning your visit by going to rsgb.org/nrc. Don't forget that as a membership benefit, RSGB members can visit the world-famous Bletchley Park estate, including the RSGB National Radio Centre, for free.

This year marked the centenary of the unique mechanical Alexanderson Alternator transmitter at Grimeton near Varberg in Sweden. GB2RS Newsreader and NRC volunteer Brian Hardy, G4BIP, travelled to Sweden for a special 70th birthday trip with his partner Hilary, G7SOI. On the 2nd of July, they were able to watch SAQ being operated on a frequency of 17.2kHz as part of the celebration. Brian was even allowed to key up the station in advance of the formal transmission and send some test messages. Despite SAQ having a power output of 80kW, nobody came back to his CQ call! However, it was a big tick on his 'bucket list'! The station is usually fired up twice a year and is well worth a visit. You can discover much more, including a fascinating YouTube video of the centenary event, via alexander.n.se The UK Six Metre Group's AGM will be held via Zoom on Sunday, the 27th of July 2025 at 17:00 UTC.

Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator. On Thursday the 24th, the RSGB 80m Club Championship Data Contest runs from 1900 to 2030 UTC. Using RTTY and PSK63 on the 80m band, the exchange is signal report and serial number. The RSGB IOTA Contest starts at 1200 UTC on Saturday, the 26th and ends at 1200 UTC on Sunday, the 27th of July. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report, serial number and IOTA reference. On Sunday the 27th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800 UTC. 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 17th of July. Space weather has been a bit like our terrestrial weather this week. We have had sunspots, some C-class solar flares, some coronal mass ejections and a large coronal hole – unsettled, you could say! Luckily, the coronal mass ejections were not Earth-directed, but the Kp index did rise to 5 on the 15th of July and again late on the 16th of July. The large coronal hole, which may have been responsible, is well south on the Sun's surface and should rotate out of Earth's view by the beginning of the coming week. Meanwhile, the Sun appears to have woken up, spot-wise, with 11 groups on the 17th of July, four of which are classed as growing, while two are stable and three are declining. Two groups are unclassified at this time. This resulted in an increase in the solar flux index to 152 on Thursday, the 17th. Overall, this means quite reasonable HF conditions considering the time of year. Recent DX spots included the JW0V DXpedition to Svalbard on both SSB and FT8, and C93RRC in Mozambique on 17m CW, plus 30, 20 and 10m FT8. Conditions have been up and down, with daytime maximum usable frequencies, or MUFs, over a 3,000km path reaching 28MHz at times, but then quickly declining to 18 or 19MHz ten minutes later. All we can advise is to keep listening! Nighttime MUFs over a 3,000km path have generally been exceeding 10MHz, and occasionally reaching 14MHz. We may start to see nighttime 14MHz openings tailing off as we head into late July. Next week, NOAA is a little pessimistic with a predicted solar flux index in the range of 118 to 130. Unsettled geomagnetic conditions, with a possible Kp of 4, are forecast for Tuesday, 22nd of July. And now the VHF and up propagation news from G3YLA and G4BAO The unsettled weather over this weekend will continue through the first part of the coming week. Some of the rain will be heavy and possibly thundery, so there is a good chance of rain scatter on the GHz bands. After mid-week, the pattern may change enough for a weak ridge of high pressure to build close to the UK and this may offer some Tropo opportunities. It may not be strong enough for it to persist through the warmth of a July day. Thus, most places will have better Tropo prospects overnight. The solar conditions have recently fired off a steady stream of aurora alerts, and we should probably expect similar in the coming week. Meteor scatter is often on people's minds during late summer since we have two showers towards the end of this month and, of course, next month's Perseids. This month, both the Delta Aquariids and the Alpha Capricornids peak around the 30th of July, but we are already in the broad spread of dates for activity. Sporadic-E is still happening on most days somewhere within Europe, but even UK stations can expect regular FT8 activity and a fair chance of CW or SSB paths for stronger events. Last Wednesday saw another early afternoon opening into the USA. These stronger events need a low Kp index, below 3, and some jet stream activity to generate turbulence that can spread upwards to the E region. In the coming week, we will certainly have some jet stream activity, so it should be worth monitoring your favourite beacons for activity. It's always helpful to have a list of favourite beacons at the ready to cover a range of directions. For example, one in Finland, Poland, Hungary, Italy and Spain should cover it. Moon declination is positive again, reaching maximum on Tuesday, the 22nd, with associated long Moon windows and high peak elevation. Path losses continue to fall until perigee today, Sunday, the 20th. 144MHz sky noise is moderate, but Thursday the 24th sees the Moon and Sun close in the sky until early the following day. And that's all from the propagation team this week.

GB2RS News Sunday, the 13th of July 2025 The news headlines: The RSGB announces speakers for its annual Convention in October Get involved with chasing awards this summer RSGB Regional Representatives elect a new Regional Forum Chair The RSGB is delighted to announce that the Keynote Speaker for its 2025 Convention will be Professor Lucie Green. She is a Professor of Physics and a Royal Society University Research Fellow at the Mullard Space Science Laboratory of the University College London. She has also presented many TV and radio programmes, including The Sky at Night and Stargazing Live. During her talk, Professor Green will provide an update on the proposed Moon-Enabled Sun Occultation Mission, which she is working on with fellow UK researchers. The project will enable the team to study the conditions that create solar storms, leading to improvements in forecasts of space weather on Earth. As well as releasing details of the Keynote Speaker, the RSGB has published a teaser of its Convention programme. This includes Neil Smith, G4DBN, who will share his experience of taking complex ideas and turning them into stories that connect with wider audiences. Many of you will be familiar with Neil from the popular BBC series “The Secret Genius of Modern Life”, for which he recreated a device invented by Leon Theremin. Bill Rothwell, G0VDE, will show you that DXpeditions don't always need to involve masses of equipment, and that one person can make a successful trip with only the luggage they carry. RSGB Propagation Studies Committee member Gwyn Griffiths, G3ZIL, will explore Travelling Ionospheric Disturbances, whilst Brian Coleman, G4NNS, will give you the latest update on the UK Meteor Radar System. Read the full list of confirmed speakers by going to rsgb.org/convention and selecting the “RSGB 2025 Convention speakers” option from the right-hand menu. The RSGB 2025 Convention is taking place at Kents Hill Conference Centre between the 10th and 12th of October. Book your ticket now and join like-minded people for a fun-filled weekend. Set yourself a challenge this summer and get involved with awards chasing. The RSGB awards are open to everyone, whatever your age, licence level and personal interests. They encourage you to push yourself further, learn something new and can even help you to make tweaks to your station to maximise performance. If HF is your mode, then visit rsgb.org/awards and get involved with the IARU Region 1 Award, which encourages you to make contacts with member countries. If VHF or UHF is your preference, then challenge yourself to the 50MHz Continents and Countries Award. Several Foundation awards are aimed at getting new licensees on the air and helping build confidence. For younger RSGB members, there are two awards designed to show the breadth that amateur radio offers. The RSGB Scouts, Cadets and Girlguiding Youth Champion, Samuel McCutchion, 2E1UEL, recently completed the Radio Surfer Award and shared his experience with us. Read how he got on by going to rsgb.org/award-stories At a recent meeting of the RSGB Regional Forum, the RSGB Regional Representatives elected George Crawford, MM0JNL, as the Regional Forum Chair. George represents Scotland South and Western Isles as the Representative for Region 1. He got involved in amateur radio in 2020 and gained his Full licence by March 2021. George has also been a GB2RS Newsreader. Along with the rest of the Regional Team, George is keen to continue to help RSGB members and the wider amateur radio community, and to promote amateur radio and the Society at public events. He will be attending Kirriemuir Show on the 19th of July to showcase amateur radio to the agricultural and rural communities. You can hear more details about that in the Special Event News section of this week's GB2RS News. Last week, senior RSGB staff and some members of the RSGB Board met for two days to discuss the next implementation phase of the Society's strategy. The discussions covered several topics, including how to ensure the Society stays relevant to the modern radio amateur. Those discussions led to some initial plans for the next six months that focus on one or two clear goals. More details of the plans will be shared over the coming weeks, including in strategy updates and at the ‘Meet the Board' session at the RSGB Convention in October. Following the RSGB's attendance at Dayton and Friedrichshafen, it was also noted that the Society is held in high esteem around the world and that many other national societies are keen to learn from the RSGB's achievements. Ben, M7FRS and John, G0JDL, are hoping to be operating aeronautical mobile in a Cessna 172 for about an hour tomorrow, Monday the 14th, over the skies of Norfolk and Suffolk. The pair will be departing from Beccles Airfield at around midday. They will initially be on the 2m band FM calling frequency of 145.500MHz before changing frequency. As per the new licensing arrangements, they will be using less than 500mW. Listen out for them, as they'd love to get you in their log! During this weekend's IARU HF World Championship, five stations will be active on the 80 to 10m bands using SSB and CW and tested under field conditions. They will be using the exact planned equipment for the WRTC 2026 event as a trial. The operating location will be a cluster of sites within the grounds of the Euston Estate in Suffolk. QSL via M0OXO's OQRS. There will be two awards available for chasers during this event, so listen out for the following callsigns: GB0WR, GB2WR, GB5WR, GB8WR and GB9WR.

On Thursday the 17th, the RSGB 70MHz UK Activity Contest runs from 1900 to 2130 UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. On Saturday the 19th, the RSGB 70MHz Trophy Contest runs from 1400 to 2000 UTC. Using all modes on the 4m band, the exchange is signal report, serial number, locator and the first two letters of your postcode. On Sunday the 20th, the RSGB International Low Power Contest runs from 0900 to 1600 UTC. Using CW on the 80, 40 and 20m bands, the exchange is signal report, serial number and transmitter power. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 10th of July 2025 Last week was characterised by settled geomagnetic conditions, but a relatively low solar flux index. The Kp index hit 5.33 on the 6th and 7th of July but was otherwise around 1 or 2 for the rest of the week. These settled conditions were helpful to HF propagation, although the maximum usable frequency over a 3,000km path didn't get much above 21MHz. This is likely to be due to the HF summer doldrums, and we are unlikely to see it rise much more until September, once the F2 layer has switched to autumnal propagation conditions. Meanwhile, the solar flux index remained steadfastly in the range of 115 to 120. This is enough to provide fair propagation, but not enough to set new DX records! But there was DX to be worked, including T30TT in western Kiribati, on the 20 and 15m bands using the FT8 Fox and Hounds mode. Also, ZD7FT was operating on St Helena Island on the 17m band using SSB, and C94RRC was active on the 10m band from Mozambique using FT8. Laurie, G3UML on the CDXC Slack group, commented that there was a lot of DX around, including FP/KV1J on the 17m band using SSB on Miquelon Island. Additionally, TY5AD was on the 17m band using CW from Benin. And FY4JI was on the 17m band using SSB from French Guiana. Now the bad news. A very large solar coronal hole will begin to face Earth this weekend. A solar wind stream flowing from this zone is expected to reach Earth with the main influence occurring today, the 13th, and tomorrow, the 14th. If the Bz of the plasma cloud points south, we can expect disturbed geomagnetic conditions and a reduction in the maximum usable frequency, or MUF for short. NOAA predicts unsettled conditions, with a Kp index of 4 between the 15th and 16th of July. The solar flux index is expected to be in the range of 105 to 125 for the next week. And now the VHF and up propagation news from G3YLA and G4BAO The hot weather continues to set the agenda in the short term. Something to note is that for VHF and UHF Tropo ducting, the ideal is for warm, dry air to sit on top of cool, moist air. These conditions are commonplace over the nearby seas as hot, dry air moves out across the coast to overlay the cool, moist air near the sea's surface. Think of the North Sea, English Channel, Irish Sea and Biscay as being very good Tropo paths in high summer. But the award goes to the Mediterranean, where very strong ducting conditions are pretty much a given if you happen to be sitting on an exotic holiday beach. Back at home... if you live inland, then you will be out of luck during the heat of the day since there is no cool, moist surface air. But in the evening, as the ground cools and perhaps cool sea air moves inland, you could find yourself coupled into the Tropo conditions that those on the coast have been enjoying all day. In other words, for most of the country, Tropo will be better overnight and early morning. The other modes are worth checking of course, especially Sporadic-E, which is continuing to give some paths on most days, at least for digital modes, but also for those using SSB or CW. Most days, there will be some direction available from the UK on the 10m band, and perhaps on the 6m band, with many online clusters to show you where the current paths are located. We really must get used to the idea that Sporadic-E can be very localised, and you will only know about it if someone calls CQ. If you do that, you may be surprised by how good conditions have been all along! Disturbed solar conditions should keep aurora as a possibility. Meteor scatter is often worth checking, with two showers peaking later in the month. The middle part of the coming week looks like turning more unsettled for a time, so rain scatter is also an option for the GHz bands. Moon declination is increasing again, reaching maximum on Tuesday, and path losses are falling. So, it's time to put the feeder back into the dish. 144MHz sky noise is moderate to start the week but decreasing to low after the weekend. And that's all from the propagation team this week.
GB2RS News Sunday, the 6th of July 2025 The news headlines: Don't miss tomorrow's RSGB Tonight@8 webinar on UK Bunkers on the Air Get involved with the GR2HQ challenge RSGB appoints a new CW Champion The next episode in the Tonight@8 series is tomorrow, Monday, the 7th of July. During the webinar, Tony Hodge, M0TNI and Jason Dale, 2E0JIV, will discuss their journey into amateur radio, what they enjoy about it and how they got involved in UK Bunkers on the Air. UKBOTA is a programme and awards scheme that encourages radio amateurs to activate Royal Observer Corps and other types of bunkers in the United Kingdom. The webinar will be livestreamed on the Society's YouTube channel and special BATC channel, allowing you to watch and ask questions live. Find out more by going to rsgb.org/webinars The IARU HF Championship contest begins in less than a week, and the RSGB Contest Committee is encouraging both individuals and clubs to get involved. During the contest, Headquarters Stations represent their countries, with the RSGB's station GR2HQ being run by a network of about a dozen stations around the UK and islands. Get involved with the GR2HQ challenge and work the stations between 1200 UTC on Saturday, the 12th of July and 1200 UTC on Sunday, the 13th of July. Certificates of Achievement will be available for all stations, and those stations achieving high scores will receive Certificates of Merit. For the full rules, go to the GR2HQ Challenge page on the Contest Committee website via rsgbcc.org RSGB Board Director Mark Jones, G0MGX, is delighted to announce that Laura Robertson, MM7BFL, has agreed to take on the volunteer role of the RSGB CW Champion. Laura will head up the RSGB's Morse-related activities and become an advocate for the use of CW. In her role, Laura will also help the Society to take CW to new audiences, with an emphasis on learning and development to further the skills of its members. Laura is a member of CWops and volunteers in the CW Academy team as a co-advisor, primarily assisting EU-based amateurs who are enrolled on the courses. She is often active on the HF bands using CW in POTA and SOTA activities, as well as from her home station. You can contact Laura via cw.champion@rsgb.org.uk. The RSGB has received a lot of interest in supporting this role, and in due course, it will be in contact with those who have said they would like to join a Morse support team. When was the last time you revalidated your licence? Ofcom notes that whilst it is a requirement to revalidate your licence every five years, it is recommended to do it annually. Put a reminder in your diary to revalidate your licence soon, as Ofcom has stated that it intends to implement phases two and three of the planned updates to the amateur radio licensing framework later this year. These phases include changes to new and Intermediate callsigns and rules for special event stations. You can find guidance on the process by going to the RSGB website and searching ‘licence revalidation'. As well as FAQs, you'll also find a link to a step-by-step video by Ofcom, which shows you the process of revalidating your licence using the online licensing portal.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of July 2025 It looks like the Space Weather Prediction Centre, which supplies the forecasts for NOAA, were overly cautious last week. Despite predicting geomagnetic disturbances, we had quite a calm week. The Kp index rose to 3.33 on a few occasions, but that was it. We ended up with settled geomagnetic conditions and a solar flux index in the 120s to 130s. A warning about the impact of a coronal mass ejection, or CME, which left the Sun on the 28th of June, appeared to come to nothing. This made a much-needed change to the unsettled conditions of previous weeks. As a result, maximum usable frequencies, or MUFs for short, over a 3,000km path have been above 21MHz at times. At night, MUFs over the same path have been consistently above 14MHz, which is normal for this time of year. In the summer, we can expect to see nighttime MUFs being consistently higher than in the winter, due to a change in ionospheric chemistry. Unfortunately, this also means that daytime MUFs are lower than in winter, leaving 28MHz open to Sporadic-E instead. According to DXMaps.com, it appears that most Sporadic-E openings on the 10m band have favoured the southeast of the UK towards Italy, Turkey and Greece. Back to F2-layer propagation now. On the 20m band, E51JD, operating from the South Cook Islands, was spotted on SSB by Laurie, G3UML, on Thursday morning. KH7AL/KH9 on Wake Island, and T30TTT on Kiribati, have also been worked on the 20m band using FT8. Next week, NOAA predicts that the solar flux index will be in the 125 to 145 range. Geomagnetic conditions are predicted to be quiet, apart from the period around the 11th and 12th of July, when the Kp index may rise to 4. And now the VHF and up propagation news from G3YLA and G4BAO This hot weather has provided some nice marine Tropo around the coasts recently as hot, dry air advects across the cooler, moist surface layer. We have also been able to see the duct move inland in the evenings. The hybrid weather pattern of low pressure to the north of Britain and high pressure to the south will continue to produce some Tropo paths, particularly across the Channel, Biscay and North Sea. Northern areas of Britain will see occasional fronts and active weather systems, together with breezier weather, making Tropo unlikely here. The higher pressure to the south means that rain scatter may not feature much unless isolated thunderstorms develop when weak weather fronts eventually reach these southern areas. In the north, it's a different matter, and there could be some heavier rain that might produce some rain scatter on the GHz bands. Meteor scatter did well during June with several important showers to boost chances. July offers two showers. The first is the low-hourly-rate Alpha Capricornids, and the second is the Delta Aquariids. Both of these peak around the 30th of July, so we have a while to wait. There have been some minor auroral events recently, and it's always possible that solar activity could lift the Kp index high enough, but we are not expecting great things. Keep a check on the Kp index at spaceweather.com to see if anything is happening. The Sporadic-E season has had occasional good days, but for much of the time, the focus of activity has been too far into Europe for the whole country to take advantage of it. To begin the coming week, the position of the jet streams suggests paths to northern Europe and the Baltic will offer best results. Later in the week, the emphasis shifts to the Balkans and Italy, and then to Iberia. The Moon reaches apogee tomorrow, the 7th, where path losses are at their highest. Moon declination is negative all week, with the lowest, or the most negative, on Wednesday, the 9th. 144MHz sky noise is moderate but increasing to a high of around 2,300 Kelvin on Wednesday. And that's all from the propagation team this week.
Elvis and Barb are back (once again) with more amazing conversations that they got at the exocad (https://exocad.com/) booth during the 4 days at IDS 2025 in Cologne, Germany (https://www.english.ids-cologne.de/). First up is two gentlemen out of Columbia that their lab 70 years ago decided that it was easier if they just started manufacturing their own materials. Juan David Jaramillo and Luis Diego Monsalve talk about the history of New Stetic (https://www.newstetic.com/en/), the regulation of getting it into 65 different countries, the world of making dental anesthesia, and how they use IDS as a way to connect with customers from around the world. Then we bring back the wonderful Steve Campbell from Nexus Dental Laboratory (https://nexus.dental/)in the UK. Steve is at IDS speaking for exocad and the new exocad ART (https://exocad.com/our-products/exocad-art). He talks about how with exocad, AI, and a video of a patient talking, we can create a video of the patient talking with their new teeth that haven't even been made yet. Steve also updates on Nexus since the last recording and the importance of encouraging your technicians to do better then you. Lastly we talk to Dr. Nicolas Rohde from VHF Milling Machines (https://www.vhf.com/en-us/). Dr. Rohde started with a business degree and a PhD in Organizational Practices. While in Maryland during school, he meets his wife and takes a job with a implant company and that's how he into dental. That company was a reseller for VHF mills and that is how he found them Dr. Rohde talks about moving back to Germany to run the US division, what sets their mills apart from others, and why they take the time to have their own CAM software to run their mills. Take it from Jennifer Ferguson from Ivoclar. If you have a PM7 (https://www.ivoclar.com/en_us/products/digital-equipment/programill-pm7) or are thinking about getting a PM7 (Take it from Barb, you should), on July 1st Ivoclar is launching the "Ivoclar Block Module" that can speed up milling emax (https://www.ivoclar.com/en_us/products/digital-processes/ips-e.max-cad) by 45%!!

Using all modes on the 2m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 25th of June. Last week was good from a geomagnetic disturbance point of view. Up until Wednesday the 25th, the Kp index had not been higher than 3.67 and had mostly been in the ones and twos. This helped HF propagation to a great extent. Sunspots have been present with the solar flux index sitting at 120 on Wednesday, the 25th. A look at the visible disk at solarham.com shows five sunspot groups facing Earth. None are ground-breaking, but they are at least helping to keep the solar flux index relatively high. Daytime F2 MUFs over a 3,000km path have been reaching 18MHz and even 21MHz at times, with 14MHz being more reliable. Sporadic-E continues to make 28MHz a useful band for short-skip, with much of Europe being workable mid-morning on the 25th, at least using FT8. Estonia, Germany, Poland, and Finland were all easily worked on FT8, but nothing was heard on the usual 10m CW and SSB frequencies. Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range. Unsettled geomagnetic conditions are forecast for the 1st to the 3rd of July, when the Kp index could reach 4. And conditions may become unsettled again on the 6th and 7th, again with a predicted Kp index of 4. But in the meantime, make the most of the Sporadic-E on the 10m band, as it won't last forever! And now the VHF and up propagation news from G3YLA and G4BAO The more traditional summer weather, with patchy rain and showers, is likely to continue for a bit longer. The more persistent rain is likely in the north, closer to low pressure near Iceland, whereas the rain may be more intermittent in southern areas, closer to high pressure over France. This probably rules out any significant Tropo in northern Britain over the coming week but does allow for the occasional enhancement in the southern half of the country. Most areas will have some rain scatter opportunities for the GHz band operators, although perhaps fewer in the south than in the north. The solar conditions have quietened down a little in terms of aurora recently but as we said last week, don't forget to look north in the twilight sky for signs of the pale noctilucent cloud. This is a high-summer phenomenon. See if you can detect any wave patterns, like ripples on a sandy beach, in the cloud. The month of June tends to be quite good for meteor input, and the last of the set, the June Bootids, peaked on Friday the 27th. So, there should be some good chances for hearing the odd ping or two or even seeing one in the evening sky after dusk. The primary mode of interest is still Sporadic-E, which is in full swing and doubtless being topped up by the Bootids meteors, which produce the main ingredient of Sporadic-E propagation – long-lived ions as they ablate, or burn up, upon entering the atmosphere. In terms of the usual search for the placement of Sporadic-E events geographically, the main jet stream interest is likely to be across the northern part of Europe for the coming week. This suggests trying paths to Scandinavia and the Baltic states, whereas for triggers due to upper air ridge patterns, use the more southern routes. The Moon has passed perigee for this month, so path losses are rising. Moon declination is still high, not going negative until Tuesday, the 1st of July. 144MHz sky noise is low, increasing to moderate by next weekend. And that's all from the propagation team this week.

GB2RS News Sunday, the 22nd of June 2025 The news headlines: Introducing the RSGB's team of young radio amateurs for YOTA Paris The RSGB celebrates International Women in Engineering Day The RSGB Exam Standards Committee publishes its annual report The RSGB has announced the team of young members who will be representing the Society at this summer's Youngsters on the Air camp. The event, hosted by the French national amateur radio society and the IARU, will take place at the historic Château de Jambville near Paris between August 18th and 25th. The team is comprised of team leader Leon, 2E0VUF, and team members Sophie, M7IJG, and Emily, M7HPU. You can read more about the camp and the team on the RSGB website at rsgb.org/yota-camp The RSGB knows that amateur radio is a great foundation for careers in Science, Technology, Engineering and Mathematics, or STEM as it is often known. That's why, for International Women in Engineering Day tomorrow, Monday the 23rd of June, the Society is sharing stories of female radio amateurs involved with STEM. From a young radio amateur who was inspired by an ARISS contact, through to a Professional Transmitting Engineer at Woofferton Transmitting Station, each one of them has a love for amateur radio and STEM activities and the career opportunities they present. Read more about them on the RSGB website at rsgb.org/inwed. The Society will also be sharing the profiles on its X and Facebook pages throughout the day tomorrow, the 23rd. Get involved by liking and sharing these motivational stories. The RSGB Examinations Standards Committee, or ESC, has published its annual report, relating to activities in 2024. The report shows that overall candidate numbers have increased to above pre-pandemic levels and are well above the extrapolation of the declining trend over the decade before the pandemic. The ESC believes that this is probably due to the availability of remote invigilation for online examinations taken at home and the increase in provision of distance learning courses, making the hobby much more accessible than in the past. You can read the full report on the RSGB website by going to rsgb.org/esc and choosing the ‘Minutes, papers and reports' option in the right-hand menu. Whether you are just starting to learn Morse code or are already an experienced operator, the GB2RS Morse Practice web page is just what you need to brush up on your skills! Created by GB2RS Newsreader Graham, G4JBD, you can select different sections of the latest RSGB news, which are then played in Morse code at the pitch and speed of your choosing. What makes this resource unique is that you can also add in different degrees of man-made noise and natural band noise, which gives you a very realistic experience of copying Morse code under poor propagation or contest conditions. Graham has recently updated the page with more options. One of these is the Farnsworth timing, which can play the individual characters at a selectable speed while allowing separate adjustment of the gap between the characters. The new version works well on smartphones and displays the text with a real-time pointer as the Morse code is sent. The GB2RS Morse Practice page can be found at tinyurl.com/gb2rsmorse Bath Based Distance Learning's next Full licence course runs from August to December, with exams in January. There is no charge for the training, but applicants must work through some pre-course material and complete a quiz to be eligible for a place. To request full details and an application form, email Bath Based Distance Learning's Team Leader, Steve, G0FUW via g0fuw@bbdl.org.uk The next in the popular 145 Alive series will take place on Sunday, the 20th of July. The event will run from 12 pm to 3 pm. There will be nets on the 2m band operating in most Maidenhead Squares across England, Scotland, Wales and Ireland. To take part on the day, all you need to do is call into a local net and make contact with others. The organisers are looking for more net controllers. If you are interested, email 145aliveuk@gmail.com. You can find more information, including details of the nets, the operators, their locations and operating frequencies on the 145 Alive Events Facebook page.

Last week, we mentioned a large coronal hole on the Sun that might cause problems. The hole is so large that it is still Earth-centric seven days later. We had expected the hole to increase the Kp index due to the solar wind emanating from it. However, as of Thursday, the 19th of June, conditions remained quiet with a Kp index of 2. As geomagnetic conditions have remained calm this past week, it has been quite good for HF. 15m has been one of the better bands, with openings to both the east and west, depending on the time. As is the way nowadays, most of the activity has been on FT8, but it has opened up opportunities to work the Far and Middle East, as well as South America. The solar flux index has generally been in the range of 130 to 150, with a peak of 161 on the 15th of June. The Sun has been active, with a near X-class solar flare being observed around sunspot region 4114. This peaked at 1805 UTC on the 15th of June. There was also an X-class solar flare at 21:49 UTC on the 17th of June. This latter event was late in the evening, so it had little impact on the UK, other than to potential paths to the west. Maximum usable frequencies, or MUFs for short, declined a little during the past week, with openings on 21MHz becoming a little scarcer. It is useful to operate as close to the MUF as possible to minimise the effects of D-layer absorption and maximise the chances of working DX. Next week, NOAA predicts the solar flux index will be in the range of 125 to 145. Unsettled geomagnetic conditions are forecast for the period from the 24th to the 27th of June, with a maximum predicted Kp index of 5. If the Kp index is low, then we have a good chance of 21 MHz openings to South America in the evening. As we pass the summer solstice, we may even expect 14 MHz to remain open to DX throughout the night. We can also expect Sporadic-E to continue to provide short-skip openings on 28 MHz, and even the lower HF bands, such as 14, 18, 21, and 24 MHz. And now the VHF and up propagation news from G3YLA and G4BAO After a week of high pressure, this weekend returns to something more normal with showery rain and a series of weather fronts and showery interludes in the coming week. This will mean that rain scatter on the GHz bands is worth considering. Also, since we are into the summer season, the chances of some rain being heavy and thundery is a good signal for rain scatter. This sequence of low-pressure weather suggests that high pressure and Tropo will be less likely to make a big impact on the coming week's operating log. Any sign of high pressure will tend to be towards the south of the UK and over the continent. In very hot weather, the conditions can be good for low-level surface ducts across cooler seas. So, if you are tempted, then go for coastal or maritime paths up the east coast or across Biscay, for example. Meteor scatter may benefit from the late June Bootids, which peak on Friday, the 27th of June and the daytime Beta Taurids, which peak on the 28th of June. These are small showers, but they can also be important for contributions to long-lived metallic ions, which are the building blocks of Sporadic-E propagation. Aurora continues to appear with occasional radio events, but there is too much daylight for anything visual. As an alternative, you might see glimpses of noctilucent clouds low down on the northern horizon. These form in the mesosphere, at about 80km, as ice crystals form on meteor dust and can exhibit complex wave patterns. These are both good omens for Sporadic-E. The summer Sporadic-E season is well underway now. It is advisable to check the usual cluster maps and the propquest.co.uk website for daily updates. It's also worth making use of the longer daylight and weather patterns over the polar regions for paths to the Far East. The Moon reaches perigee, its closest point to Earth, tomorrow, the 23rd, so path losses are low. Moon declination also reaches a maximum positive value on the 25th of June. This will mean that there are long Moon windows. 144MHz sky noise is moderate, increasing to high by tomorrow, the 23rd. The New Moon is on the 25th of June, so expect high noise levels due to its proximity to the Sun. And that's all from the propagation team this week.
GB2RS News Sunday, the 15th of June 2025 The news headlines: Book now to secure your place at the RSGB 2025 Convention The RSGB launches the “SES Cookbook” The RSGB Operating Advisory Service issues advice The RSGB annual Convention is a fantastic opportunity for radio amateurs to meet, learn and share experiences. Whether you're newly licensed or have years of experience, there is always more to discover. That's why the Society is excited to introduce this year's theme: “Discover, Learn, Progress”. Whether you want to discover something new, learn more about a particular aspect of amateur radio, or progress and develop your skills, you'll find something at the Convention to explore and enjoy. The prestigious event will take place between October 10th and 12th at Kents Hill Conference Centre in Milton Keynes. Book now to secure your place in joining like-minded people for what is also one of the best social events in amateur radio. Take advantage of the early-bird prices by going to rsgb.org/convention. The Society is delighted that the event will be sponsored again by Martin Lynch and Sons. Special event stations are popular around the world and a great source of fun and excitement for organisers and QSO chasers. They can also be a fantastic tool for outreach, allowing you to demonstrate amateur radio and encourage people to find out more. But how do you organise an event to achieve all those objectives? The RSGB has just launched a new web section that focuses on special event stations. For RSGB members and Affiliated Clubs, there is an online guide called the SES Cookbook, which offers a wide range of practical guidance to help you deliver the best experience for your visitors and the organisers. The guide covers a wide range of topics, including how to apply for a special event station callsign, the stages of the planning process, publicising your event to attract visitors and how to make a good number of contacts. For non-RSGB members, there is a simple guidance document that outlines the main things to consider when planning this type of event. The new section also draws together existing information about permanent special event stations as well as QSL guidance. If you're planning an event for this year, or even for next year, now is the time to make the most of this comprehensive guide. Go to rsgb.org/ses to find out more. The RSGB Operating Advisory Service, or OAS, provides advice to members on dealing with situations that are not within the spirit of amateur radio. From time to time, this activity goes beyond what is classed as acceptable behaviour and requires action to be taken. In these circumstances, the OAS recommends reporting the matter directly to Ofcom and to the police in the case of issues which could be classed as harassment, stalking or hate crimes. Experience has shown that this carries more weight coming directly from the people hearing or suffering the problem rather than a third party, such as the RSGB. If you hear anything that is not acceptable behaviour, contact the RSGB OAS first, and the team will suggest the correct course of action. Once Ofcom and the police have issued reference numbers, these should be passed to the Operating Advisory Service. You can contact OAS via oas@rsgb.org.uk The RSGB has submitted responses to a pair of Ofcom consultations. The first considered a series of licence exemption updates, including arrangements for some visiting radio amateurs to the UK. The second concerned filing procedures for the growing number and variety of satellites. Both replies were developed by the RSGB Spectrum Forum, drawing on its members' wide breadth of expertise. The Spectrum Forum expects that there will be further updates to both topics. Find the full replies by going to rsgb.org/spectrumforum and selecting the ‘Papers and Consultations' option from the right-hand menu. The RSGB recently announced two new volunteering opportunities. The RSGB CW Champion will help the Society in taking Morse code to new audiences. Tasks will vary from developing the CW content on the RSGB's website through to developing and supporting a team of enthusiastic individuals who can support CW-related activities. The second role requires an individual with experience in science, technology, engineering and mathematics. The RSGB STEM Champion will help the Society to reach new audiences, build relationships with related organisations and encourage more young people into STEM careers. Go to rsgb.org/volunteers to read the full role descriptions and learn how to apply.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 12th of June 2025 Propagation was a mixed bag last week, with occasional Kp index rises but a solid solar flux index, which hit 141 on Thursday, the 12th. We also had some sporadic-E short-skip conditions on the HF bands, which brought some surprises. We are now in June, so the summer HF doldrums are well underway. But that doesn't mean that the fun has gone from the HF bands. Daytime maximum usable frequencies over a 3,000km path have been around 18 to 20 MHz, so the main active band has been 20m. Paul, GM4ULS, reports that there was a spectacular inter-G event on the morning of Tuesday, the 10th of June. Whilst activating special event station GB70RS from Perth, he worked a mini pile-up of English stations from anywhere between Southampton and Manchester. This was between 0949 and 1022 UTC on 14.210 MHz. He said it sounded like the 40m band at times! We think this was probably a Sporadic-E event, which often creates strong but short-lived paths across the UK on the HF bands in the summer. We normally think of Sporadic-E as affecting the 10m band, but the lower bands are also often implicated. Have you worked anything unusual via Sporadic-E? If you have, please send your reports to radcom@rsgb.org.uk Otherwise, DX on the HF bands has been a little sparse, with paths opening to South Africa and South America on the 20 and 17m bands at times. Perhaps this is a good time to work some Summits on the Air or World Wide Flora and Fauna stations in Europe. These are usually QRP stations that appreciate your contacts. Next week, NOAA predicts the solar flux index will be in the 120 to 130 range. Unfortunately, geomagnetic conditions are predicted to be unsettled, thanks mainly to the return of a massive coronal hole on the Sun. Disruption was due to start around the 14th, but due to the hole's size, this could continue for at least three days with a maximum Kp index of 6. Expect the HF bands to be disrupted with lower maximum usable frequencies as the plasma in the solar wind hits the Earth. It may be a good time for visible aurora hunting, though. And now the VHF and up propagation news from G3YLA and G4BAO The high summer conditions have brought an increasing chance of Sporadic-E, particularly on digital modes, with DXmaps.com plots showing plenty of paths on most days. Many of these are possibly associated with turbulence generated by jet streams in the weather part of the atmosphere. These send atmospheric gravity waves upwards to affect the E region. It's this association with specific weather features that makes Sporadic-E sporadic in a geographical sense. If so, in the coming week, the jet streams are mainly over the northern fringe of Europe. These suggest a better chance of paths to Scandinavia with fewer options to the south to support paths to the Mediterranean and the Balkans. In any event, June is high season for Sporadic-E, so remember to check the 6m band either mid-morning or late afternoon. The early thundery weather at the end of last week was useful for rain scatter on the GHz bands, and it is just possible it will return for the end of the coming week. In between times, it will be a high-pressure story that will dominate and may well produce some useful Tropo conditions. However, note that in the hot days of summer, inversion conditions and Tropo will be better at night and tend to weaken by the middle of the morning. Meteor scatter will have been boosted by two showers on the 7th and 8th of June, and, since they were broad peaks, there should be some meteor input left to see us through the coming week. For EME, sky noise is dropping. Low declination is now starting to decrease. So, Moon windows and peak elevation are improving. EME conditions are classed as poor to moderate today, the 15th of June, but are then good on the 21st and 22nd of June. And that's all from the propagation team this week.

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

Ralph speaks to Washington Post columnist Dana Milbank about the Trump Administration's path of destruction in our federal government. Then, Ralph welcomes legendary public interest lawyer Alan Morrison to discuss the President's authority to impose tariffs and other constitutional questions.Dana Milbank is a nationally syndicated op-ed columnist for the Washington Post. He also provides political commentary for various TV outlets, and he is the author of five books on politics, including the New York Times bestseller The Destructionists and the national bestseller Homo Politicus. His latest book is Fools on the Hill: The Hooligans, Saboteurs, Conspiracy Theories and Dunces who Burned Down the House.I shouldn't be amazed, but Mike Johnson never ceases to amaze me with the rapidity with which he'll just drop to his knees whenever Trump says something.Dana MilbankWe're going to know this shortly, but it does appear that Trump's honeymoon may be over in the House as the conservatives finally seem to be finding their backbones. But I've thought that might happen before and then only to find out that they, in fact, they could not locate their backbones. So I don't want to be premature.Dana MilbankTrump seems to be gambling (and the administration seems to be gambling) that ultimately the Supreme Court is going to a wholesale reinterpretation of the Constitution to grant these never-before-seen executive powers, and it's possible that he's right about that. We're not going to know that. There have been a couple of preliminary rulings that seem friendly to Trump, but none of those is final, so we can't really be sure of it.Dana MilbankMy guess is that Chief Justice Roberts is seeing his legacy heading toward the ditch after his decision of Trump v. United States, where he said that Presidents cannot be criminally prosecuted….My guess is he's going to unpleasantly surprise Trump in the coming months.Ralph NaderAlan Morrison is the Lerner Family Associate Dean for Public Interest & Public Service at George Washington Law School. He currently teaches civil procedure and constitutional law, and previously taught at Harvard, NYU, Stanford, Hawaii, and American University law schools. He has argued 20 cases in the Supreme Court and co-founded the Public Citizen Litigation Group in 1972, which he directed for more than 25 years.It's inevitable that even for a non-economist like myself to understand that [the costs of tariffs] are going to be passed on. Other than Donald Trump, I don't think there's anybody who believes that these taxes are not going to be passed on and that they're going to be borne by the country from which the company did the exporting.Alan MorrisonIt's an uphill battle on both the statutory interpretation and the undue delegation grounds, but our position is rather simple: If the Congress doesn't write a statute so that there's something that the government can't order or do, then it's gone too far. In effect, it has surrendered to the President its power to set policy and do the legislative function. Interestingly, Trump has trumpeted the breadth of what he's doing here. He calls it a revolution. Well, if we have revolutions in this country, my copy of the Constitution says that the Congress has to enact revolution and the President can't do it on its own. So we think we've got a pretty strong case if we can get it to court.Alan MorrisonOne of the things that I've been struck by is that laws alone cannot make this country governable. That we can't write laws to cover every situation and every quirk that any person has, especially the President. We depend on the norms of government—that people will do things not exactly the way everybody did them before, but along the same general lines, and that when we make change, we make them in moderation, because that's what the people expect. Trump has shed all norms.Alan MorrisonNews 4/9/251. Our top story this week is the killing of Omar Mohammed Rabea, an American citizen in Gaza. Known as Amer, the BBC reports the 14-year-old was shot by the Israeli military along with two other 14-year-old boys “on the outskirts of Turmus Ayya” on Sunday evening. Predictably, the IDF called these children “terrorists.” According to NJ.com – Rabea formerly resided in Saddle Brook, New Jersey – Rabea's uncle sits on the board of a local Palestinian American Community Center which told the press “The ambulance was not allowed to pass the checkpoint for 30 minutes, a denial in medical treatment that ultimately resulted in Amer's death…[his] death was entirely preventable and horrifically unjust. He was a child, a 14-year-old boy, with an entire life ahead of him.” The Rachel Corrie Foundation, founded in honor of the American peace activist killed by an Israeli bulldozer while protesting the demolition of a Palestinian home, issued a statement reading “Rabea's death…was perpetuated by Israeli settlers who act with impunity…We believe that if our own government demanded accountability…Rabea would still be alive.” The Council on American-Islamic Relations (CAIR) has sent a letter to Attorney General Bondi demanding an investigation, but chances of the Trump administration pursuing justice in this case are slim.2. Meanwhile, President Trump seems to be driving the U.S. economy into a deep recession. Following his much-publicized tariff announcement last week – which included 10% tariffs on uninhabited Heard and McDonald Islands – the S&P dipped by 10.5%, among the largest drops in history, per the New York Times. Far from making Trump back off however, he appears dead set on pushing this as far as it will go. After the People's Republic of China responded to the threat of a 54% tariff with a reciprocal 34% tariff, Trump announced the U.S. will retaliate by upping the tariff to a whopping 104% on Chinese imports, according to the BBC. Reuters reports that JP Morgan forecasts a 60% chance of a recession as a result of these tariffs.3. In more foreign affairs news, on Friday April 4th, South Korea's President Yoon Suk Yeol was officially removed from office by that country's Constitutional Court, “ending months of uncertainty and legal wrangling after he briefly declared martial law in December,” per CNN. The South Korean parliament had already voted to impeach Yoon in December of 2024. The court's decision was unanimous and characterized the leader's actions as a “grave betrayal of the people's trust.” Upon this ruling being handed down, Yoon was forced to immediately vacate the presidential residence. A new election is scheduled for June 3rd. Incredible what a political and judicial class unafraid to stand up to lawlessness can accomplish.4. Speaking of ineffectual opposition parties, one need look no further than Texas' 18th congressional district. This safe Democratic district – including most of central Houston – was held by Congresswoman Sheila Jackson Lee from 1995 until her death in 2024. According to the Texas Tribune, Lee planned to run yet again in 2024, triumphing over her 43-year-old former aide Amanda Edwards in the primary. However, Lee passed in July of 2024. Edwards again sought the nomination, but the Harris County Democratic Party instead opted for 69-year-old former Houston Mayor Sylvester Turner, per the Texas Tribune. Turner made it to March of 2025 before he too passed away. This seat now sits vacant – depriving the residents of central Houston of congressional representation and the Democrats of a vote in the House. Governor Gregg Abbot has announced that he will not allow a special election before November 2025, the Texas Tribune reports. This is a stunning Democratic own-goal and indicative of the literal death grip the gerontocratic old guard continue to have on the party.5. One ray of hope is that Democratic voters appear to be waking up the ineffectual nature of the party leadership. A new Data for Progress poll of the 2028 New York Senate primary posed a hypothetical matchup between incumbent Senator Chuck Schumer and Democratic Socialist firebrand Congresswoman Alexandria Ocasio-Cortez – and found AOC with a staggering lead of 19 points. This poll showed AOC winning voters under 45 by 50 points, over 45s by eight points, non-college educated by 16 points, college educated by 23 points, Black and white voters by 16 points, and Latinos by 28. Schumer led among self-described “Moderates” by 15 and no other group. It remains to be seen whether the congresswoman from Queens will challenge the Senate Minority Leader, but this poll clearly shows her popularity in the state of New York, and Schumer's abysmal reputation catching up with him.6. Another bright spot from New York, is Zohran Mamdani's mayoral candidacy and specifically his unprecedented field operation. According to the campaign, between April 1st and April 6th, volunteers knocked on 41,591 doors. No mayoral campaign in the history of the city has generated a grassroots movement of this intensity, with politicians traditionally relying on political machines or enormous war chests to carry them to victory. Mamdani has already reached the public financing campaign donation cap, so he can focus all of his time and energy on grassroots outreach. He remains the underdog against former Governor Andrew Cuomo, but his campaign appears stronger every day.7. Turning to the turmoil in the federal regulatory apparatus, POLITICO reports Secretary of Health and Human Services Robert F. Kennedy Jr. has eliminated the Freedom of Information Act offices at the Centers for Disease Control, and other HHS agencies. An anonymous source told the publication that HHS will consolidate its FOIA requests into one HHS-wide office, but “Next steps are still in flux.” In the meantime, there will be no one to fulfill FOIA requests at these agencies. This piece quotes Scott Amey, general counsel at the Project on Government Oversight, who said this “sends a wrong message to the public on the administration's commitment to transparency.” Amey added, “I often say that FOIA officers are like librarians in knowing the interactions of the agency…If you don't have FOIA officers with that specific knowledge, it will slow down the process tremendously.”8. At the Federal Trade Commission, Axios reports the Trump administration has “paused” the FTC's lawsuit against major pharmacy benefit managers, or PBMs, related to “the drug middlemen…inflating the price of insulin and driving up costs to diabetes patients.” The case, filed against CVS Caremark, OptumRx and Express Scripts was halted by the FTC in light of “the fact that there are currently no sitting Commissioners able to participate in this matter.” That is because Trump unlawfully fired the two remaining Democratic commissioners Alvaro Bedoya and Rebecca Slaughter. In a statement, former FTC Chair Lina Khan called this move “A gift to the PBMs.”9. One federal regulatory agency that seems to be at least trying to do their job is the Federal Aviation Administration. According to the American Prospect, the FAA has “[has] proposed [a] rule that would mandate Boeing update a critical communications malfunction in their 787 Dreamliner plane that could lead to disastrous accidents.” As this piece explains, “very high frequency (VHF) radio channels are transferring between the active and standby settings without flight crew input.” The FAA's recommendation in is that Boeing address the issue with an update to the radio software. Yet disturbingly, in one of the comments on this proposed rule Qatar Airways claims that, “[they have] already modified all affected…airplanes with … [the recommended software updates] …However … flight crew are still reporting similar issues.” This comment ends with Qatar Airways stating that they believe, “the unsafe condition still exists.” Boeing planes have been plagued by critical safety malfunctions in recent years, most notably the 2018 and 2019 crashes that killed nearly 350 people.10. Finally, on a somewhat lighter note, you may have heard about Bryan Johnson, the tech entrepreneur dubbed “The Man Who Wants to Live Forever.” Johnson has attracted substantial media attention for his unorthodox anti-aging methods, including regular transfusions of plasma from his own son. But this story is not about Johnson's bizarre immortality obsession, but rather his unsavory corporate practices. A new piece in New York Magazine focuses on the lawsuits filed against Johnson by his all-too-mortal workers, represented by eminent labor lawyer Matt Bruenig. This piece relays how Johnson “required his staffers to sign 20-page NDAs,” and an “opt-in” document which informed his employees they had to be comfortable “being around Johnson while he has very little clothing on” and “discussions for media production including erotica (for example, fan fiction including but not limited to story lines/ideas informed by the Twilight series and-or 50 Shades of Grey.)” Bruenig says, “That stuff is weird,” but his main interest is in the nondisparagement agreements, including the one Johnson's former employee and former fiancée Taylor Southern entered into which has further complicated an already thorny legal dispute between Johnson and herself. Now Bruenig is fighting for Southern and against these blanket nondisparagement agreements in a case that could help define the limits of employer's power to control their workers' speech. Hopefully, Bruenig will prevail in showing that Johnson, whatever his pretensions, truly is a mere mortal.This has been Francesco DeSantis, with In Case You Haven't Heard.

There are a variety of antennas that a ham can use on the VHF and UHF bands, from simple whips, all the way up to directional beams. This month's podcast walks you through the various types and their use cases.
The Kenai Peninsula Borough School District on Monday published a list of nine schools it's thinking about closing as a way to balance its budget for the upcoming fiscal year. For several years the U.S. Coast Guard's emergency VHF radio system has experienced outages across Southeast and the Gulf of Alaska. Nine rural fire departments on the Kenai Peninsula are getting more than $80,000 in grants to boost firefighting efforts.
The latest ENA Podcast takes a look at the rare, but potentially dangerous, threat of viral hemorrhagic fevers in the emergency department. Mary Choi with Centers for Disease Control and Prevention talks about what ED nurses and emergency departments need to consider when it comes to identification, treatment and mitigating the spread of VHF.
Foundations of Amateur Radio The other day I noticed a flurry of QSL card designs come across my screen and it sparked me into action on actually creating such a card for myself. I've previously talked about what I think of the current offerings in terms of validating contacts, but having a QSL card design is step one of confirming a contact, well, technically step two, since you have to make the contact first. I'm intending to use SVG as the design platform, since it's a text file that describes an image, so I can use my favourite command line tools, like "grep", "sed", "cut" and "awk" to replace parts of the file, so I can make a personal card for every contact, but that's a story for another day. Accompanying the rush of new card designs was an intriguing hash tag, #hamchallenge. Looking into this further I discovered a project by Fabian DJ5CW with an accompanying website, hamchallenge.org. When you go there, and you should, you'll discover 52 challenges with varying levels of difficulty that you can use as inspiration to do something with your hobby. The usual suspects are there, things like week 42, receive an SSTV image, or week 50, receive an APRS message or beacon. Then there are those like week 38, make a contact on Morse code, and week 19, simulate an antenna. It goes well beyond those essential skills into important stuff like, week 14, implement and describe a backup solution for your ham radio log, and week 24, make a contribution to an Open Source ham radio software package. Not all challenges require an amateur license either. For example, week 32, listen to a broadcast station from another country, is open to anyone with a sense of wonder. The difficulty level is included in a challenge, so week 17, which VHF or UHF repeater is closest to you, is marked as easy, where week 3, work another continent on 80m or 160m, is marked as hard. There's also helpful information about a challenge, for example week 6, take part in a contest, includes a link to the contestcalendar.com website where you'll find most if not all amateur radio contests. Of course this is your hobby and it's not up to me to tell you what to do, but I have to say that the items in this list are exciting, they speak to me and I have to say that I'll be taking inspiration from this list and I recommend that you do too. Not all of the challenges will be something new to everyone. I've already built an antenna, participated in a contest, worked a 10m FM repeater and several other things on this list, but if I'm going to make a Morse Code contact, I'm sure going to have to find some time to actually, you know, learn Morse. I know this will come as music to the ears of several of my amateur friends. There will be challenges that speak to you more than others, week 21, create a GNU radio flowgraph, is right up my alley, but that might not be the case for you. If you feel inspired, week 47 encourages you to submit an idea for the Ham Challenge next year. So, thank you to Fabian for the efforts and many amateurs who have already contributed to this adventure. What a beauty. I'm off to finish my QSL card. I'm Onno VK6FLAB

Adam Kimmerly, K6ARK, discovered amateur radio almost by accident through his participation in the San Diego Mountain Rescue organization. Adam's ham radio interests evolved from VHF to HF SOTA, or Summits on the Air, learning CW, and reaching SOTA Mountain Goat status. The need for light weight kits to carry to the most difficult to reach summits demanded new expertise in antenna design and construction with 3D printing. K6ARK tells his ham radio story in this QSO Today.
