In this episode titled "Ham Radio (Amateur Radio)," host Mike Dell reflects on his youth prior to the Internet and video games, mentioning his limited interaction with CB radio rather than ham radio. He explains the differences between CB and ham radio, particularly the wider range and more diverse frequencies available to amateur radio operators. Mike discusses the various frequency bands in ham radio, starting with UHF, VHF, and HF, detailing their uses and characteristics. He explains concepts like frequency modulation (FM) and amplitude modulation (AM), along with how repeater stations work to extend transmission ranges. Mike also recounts his personal experiences with these frequencies, mentioning how he engaged with fellow hams while fishing and discussing the unique phenomena of tropospheric ducting that allowed him to communicate long distances. He then dives into specific bands, starting with the two-meter band, explaining its popularity, accessibility for new technicians, and how equipment like inexpensive radios can enable communication across towns. Mike also shares anecdotes about his experiences and connections with other ham operators, emphasizing the camaraderie within the amateur radio community. Continuing, he describes several other HF bands, explaining each band's unique properties, propagation characteristics, and modes of communication available within them. Mike touches on historical aspects of obtaining licenses, mentioning how the requirements have shifted over the years, specifically noting the discontinuation of Morse code testing for access to ham radio. Additionally, Mike elaborates on various digital modes that have emerged within ham radio, contrasting them with traditional radio communication, and shares fond memories of his early experiences, such as using packet radio to send messages to his father before email became commonplace. As the episode wraps up, Mike reflects on the significance of ham radio in his life, noting how it has helped him form lasting friendships and connections. He concludes by expressing his commitment to the hobby and the joy he finds in it, inviting listeners to explore the world of amateur radio and reminding them that he will return for the next episode.

GB2RS News Sunday, the 23rd of November The news headlines: Could your skills and experience support the RSGB Board? Let the Society know your plans for British Science Week 2026 The RSGB is looking for a volunteer Accessibility Champion Do you have skills and experience that would make you an asset to the RSGB Board? The RSGB elections process has begun, and there are two routes to becoming a Board Director. This week's focus is on Nominated Directors, and there are two vacancies this year. Nominated Directors are selected by the Society's Nominations Committee, and then the RSGB membership votes to endorse them at the AGM. The closing date for these vacancies is the 5th of December 2025, so don't delay! There is no functional difference between a Nominated or Elected Director, and all serve the Board in the same way for a three-year term. If you'd like to know more about what is required of an RSGB Board Director, the first step is to read the candidate pack for Elected Directors on the RSGB website at rsgb.org/elections  After that, if you'd like to express your interest in being a Nominated Director or would like an informal chat, email the RSGB Company Secretary, Stephen Purser, GW4SHF via company.secretary@rsgb.org.uk Preparations for British Science Week 2026 are already well underway. RSGB British Science Week Co-ordinator Professor Ian Neal, G7IGN, is working on guidance and activity suggestions that you could use to get involved. The annual event is a celebration of science, technology, engineering and maths and is run by the British Science Association. It has chosen ‘curiosity' as its theme for 2026, which fits perfectly with amateur radio. This campaign is a brilliant opportunity for radio amateurs to share their passion with others. This could be through organising an open day for the local community, setting up a buildathon for a club evening, operating a special event station from your local library or even supervising your friends and family in making their first QSO – the options are endless. If this has piqued your interest, and you would like to share your thoughts, ideas and plans with Ian, get in touch via bsw@rsgb.org.uk. You can see what other people did last year and find the RSGB's resource bank at rsgb.org/bsw The RSGB is looking for a proactive and knowledgeable volunteer to serve as its new Accessibility Champion. This important role will focus on ensuring that people with disabilities can fully participate and enjoy everything that amateur radio has to offer. Key responsibilities of the role will be engaging with the amateur radio community, serving as a point of contact and signposting people to resources that can help them, as well as raising awareness of the challenges faced by individuals and sharing inspiring stories. If you have a strong understanding of accessibility issues, ideally with personal experience or professional expertise, and are passionate about inclusion within amateur radio, the Society would love to hear from you. If you're interested in finding out more, including having a chat about the role, please firstly read the full role description on the RSGB website at rsgb.org/volunteers  and then contact RSGB Board Director Nathan Nuttall, 2M0OCC. Did you see the Meteor Beacon Project presentation by Brian Coleman, G4NNS, at the RSGB Convention or on the Convention livestream? Would you like to explore the science that the project supports and be involved in the technical research and activities? Brian is creating a small group to contribute to the ongoing development of the project and will start to record, classify and analyse the data the system can already gather. If you'd like to know more about the project, you can watch Brian's presentation on the RSGB YouTube channel at youtube.com/theRSGB  If you'd like to be part of the ongoing development group, please contact Brian via brian@brcg4nns.org  for a chat about what would be involved. Today is the last day to give the RSGB HF Contest Committee your comments to help shape the rules for HF contests in 2026. The online survey includes questions on ‘Self-Spotting' and ‘Slow speed CW'. You can find the survey online via tinyurl.com/hfcontests Please send details of all your news and events to radcom@rsgb.org.uk. The deadline for submissions is 10am on Thursdays before the Sunday broadcast each week.  And now for details of rallies and events On Sunday, the 30th of November, Bishop Auckland Radio Amateur Club's Rally is taking place at Spennymoor Leisure Centre, County Durham. Traders, catering, ample parking and disabled facilities will be available. For more information and downloadable trader forms, visit barac.org.uk The Mid Devon Amateur Radio and Electronics Fair 2025 will be held on the 7th of December at Winkleigh Sports and Recreation Centre. The doors will be open from 9 am to 1 pm. Entry costs £3 per person and there is no charge for partners and under-16s. For more detail,s contact Phil, G6DLJ on 07990 563 147 or email wrg2024@hotmail.com Now the Special Event news Special event station GB130WRD is active until the 30th of November to mark the 130th anniversary of the discovery of X-rays. Recently, the station was spotted using FT8 on the 40m band. QSL directly to M0KZT. See QRZ.com  for more information. Special callsign GB70RS is in use to celebrate the 70th anniversary of the RSGB's weekly news service GB2RS, which has been running continuously since the 25th of September 1955. A team of amateurs is using the callsign on a variety of bands and modes. QSL via the Bureau, Logbook of the World and eQSL. For more information, visit the GB70RS page at QRZ.com Now the DX news Phill, C21TS, is active from Nauru, OC-031, until the 30th of November. The station is often spotted on the HF bands using FT8. QSL via Logbook of the World or OQRS. Darek, TJ1GD, is operating as TL8GD from the Central African Republic until the 30th of November. He is using CW, FT8 and SSB on the HF bands. QSL via Club Log's OQRS, Logbook of the World or via SP3EOL. Now the contest news On Tuesday the 25th, the RSGB SHF UK Activity Contest runs from 1930 to 2230UTC. Using all modes on the 13cm band, the exchange is signal report, serial number and locator. On Wednesday the 26th, the UK and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. On Thursday the 27th, the 3.5MHz RSGB Autumn Series CW Contest runs from 2000 to 2130UTC. Using CW on the 80m band, the exchange is signal report and serial number. The CQ World Wide DX CW Contest starts at 0000UTC on Saturday, the 29th and ends at 2359UTC on Sunday, the 30th of November. Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ zone. The UK is in Zone 14. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 20th of November After the solar mayhem we reported in last week's GB2RS News, the Sun has been relatively quiet over the past week. The maximum Kp index we saw was 4, on Monday, the 17th of November, but otherwise it was often below 1 or 2. The result is that the ionosphere has been more stable and DX has been more forthcoming. Unfortunately, this coincided with a drop in sunspot numbers, and the solar flux index fell from 163 on the 12th to 123 on Thursday, the 20th. However, 123 is still enough to get things moving, and we have seen some good DX being worked. CDXC's Slack chat group has reported several impressive contacts. VK9DX on Norfolk Island was worked on the 15m band using CW; ZL7/LZ1GC on the Chatham Islands was logged on the 40m band using CW; and S79/OK6RA in the Seychelles appeared on the 10m band using CW. Another interesting spot was JA7BXS on the 80m band using CW on the morning of Thursday, the 20th, showing that the low bands are becoming more interesting as we head into winter. DX on the 80m band has little to do with the solar flux index but can be influenced by geomagnetic disturbances; hence, these quieter periods have allowed the 40 and 80m bands to shine. For the coming week, NOAA predicts that the solar flux index may decline even more, perhaps down to 105 or 110. However, it does look like our run of quiet geomagnetic indices may come to an end, with a Kp index of 5 predicted for the 24th to the 27th of November. In fact, we could have unsettled geomagnetic conditions until the end of the month. So, this may be a good time to start concentrating on the lower bands, such as 40 and 80m. You never know, they might surprise you! And don't forget, the CQ World Wide CW Contest is taking place during the weekend of the 29th and 30th – always a good opportunity for DX. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of unsettled weather is very much in a cold phase, but although it continues to be unsettled, it will be milder and wetter in the coming week. Perhaps more important is that at times it will be very windy with gales in some areas. For propagation, this means that the one feature absent from the present charts is any high pressure to bring tropo conditions. This means that other modes take on more importance. Auroras have provided some recent interest and, although there's nothing dramatic in the immediate future, keep a watching brief for a rising Kp index. A good guide for impending activity is if the Kp index increases above 5. The rain scatter prospects are likely to be good during the coming week as several active frontal systems cross the country. Notably, the evening of Wednesday the 19th saw trans-North sea propagation visible on the Margate 24GHz WebSDR. This extended into the morning of Thursday the 19th, but unfortunately, no coastal stations were around to make QSOs. While rain scatter is a GHz band activity, on the lower band,s you may find some increase in static levels due to lightning activity or even snow static before the weather turns milder. There is not expected to be a strong showing of Sporadic-E in the coming week since we are well out of season. Southern UK stations should continue to watch out for fleeting F-layer DX openings on 50MHz, especially to Africa and Asia. For EME operators, the Moon's declination is at its lowest and negative all week, so Moon window lengths are short and peak elevation is low. We passed apogee on the 20th of November, so path losses are decreasing again. 144MHz sky noise is high today, the 23rd, but will become lower as the week progresses. And that's all from the propagation team this week.

Ce 234e épisode de Pos. Report refait le match de La Boulangère Mini Transat avec ses deux vainqueurs, Mathis Bourgnon, sur le proto Assomast (plan Etienne Bertrand), et Paul Cousin (AFP-Biocombustibles) en série, mais également avec Benoît Marie, deuxième en proto sur son plan Manuard à foils Nicomatic-Petit Bateau.Nous revenons d'abord sur l'annulation de la première étape, forcément frustrante pour Benoît Marie, qui était alors nettement en tête mais a accepté la décision, avant de faire route directement vers les Canaries alors que quasiment toute la flotte s'est réfugiée dans des ports portugais et espagnols.Nos invités confient leur état d'esprit au départ de la deuxième, le 25 octobre, et leur choix de route au moment de quitter les Canaries, avec une trajectoire est pour Mathis Bourgnon, qui l'avait travaillée avant de s'élancer, notamment avec Benoît Marie. Ce dernier raconte ensuite ses deux folles journées en volant, avec à la clé le record des 24 heures en Mini (352,59 milles, à 14,69 noeuds de moyenne), puis sa première sérieuse avarie en retombant d'une vague, avec la perte de son foil tribord et un trou dans la coque à combler. Mathis Bourgnon confie qu'il n'a alors pas vraiment réalisé que son concurrent était handicapé, plus focalisé sur son duel avec Alexandre Demange (DMG Mori Sailing Academy 2).Paul Cousin détaille quant à lui sa stratégie en ce début d'étape, avec une route sud que quasiment tous ont empruntée, mais qu'il fallait savoir doser, avant une seconde partie de transat qui a consisté à bien anticiper les rotations de l'alizé. Les trois marins racontent enfin les derniers jours de course, avec une nouvelle avarie pour Benoît Marie sur son bout-dehors et son spi max, qu'il a réussi dans un premier temps à circonscrire, avant de tout casser à une cinquantaine de milles de l'arrivée et d'appeler Mathis Bourgnon à la VHF pour le féliciter.Ce dernier explique ne pas avoir alors trop compris qu'il allait gagner et avoir vraiment réalisé une fois sur le ponton à Saint-François, dans les bras de ses parents, dont son père Yvon, vainqueur jour pour jour trente ans plus tôt. Paul Cousin confie de son côté l'état de fatigue extrême dans lequel il était au moment de couper la ligne en vainqueur, parce qu'il a beaucoup barré pendant les deux semaines de course, y compris la nuit, pour faire la différence sur ses poursuivants. Nos trois invités finissent par se projeter sur la suite : Paul Cousin rêve de Figaro, Benoît Marie de Trophée Jules Verne, Mathis Bourgnon d'Ocean Fifty ou d'Imoca.Diffusé le 18 novembre 2025Générique : Fast and wild/EdRecordsPost-production : Grégoire LevillainPhoto : Arnaud Pilpré / La Boulangère Mini TransatHébergé par Ausha.

Using all modes on the 4m band, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of November 2025 Last week saw one of the most dramatic auroral events of this cycle. Three X-class solar flares, which sparked coronal mass ejections, joined together to give us a peak Kp index of 8.67, with a solar wind speed in excess of 950 kilometres per second. The result was extensive visible aurora in the US and Canada, although clouds prevented much of its visibility in the UK. The good news from a radio point of view was that the solar wind's Bz, or interplanetary magnetic field, mostly pointed north or was neutral in the latter stages. This saved the Earth from a lot of its effects. The next day, HF propagation appeared to be almost normal with maximum usable frequencies, or MUFs, over a 3,000km path still exceeding 24MHz at times. By Thursday the 13th, it was mostly over 28MHz, although there were times it dropped dramatically, and signals were weak and watery at best. You could tell that there had been some disruption to HF by a lack of spots on the CDXC Slack group. While Stan, ZL7/LZ1GC on Chatham Island had been spotted on the 11th, there was very little to report the next day as the Kp index rose to 5. Next week, NOAA predicts that the solar flux will remain in the 160 to 170 range. However, we can expect a repeat of unsettled geomagnetic conditions this weekend, possibly due to a large coronal hole that became Earth-facing on the 13th. Likewise, the 20th and 21st of November may be unsettled, with a predicted maximum Kp index of 4. After the following weekend, we can also expect more unsettled conditions, especially around the 24th to the 27th, which could see the Kp index rise to 5 or even higher. Expect decreased MUFs and less HF activity if this is the case. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of unsettled weather is likely to continue into the coming week. High pressure is always being kept at arm's length, so there is no real tropo flavour to proceedings. The rain prospects are very strong, with, if anything, too much rain in some areas. During the coming week, colder northerly air will mean that some snow is possible on the northern hills. So there remains a possibility of rain scatter on the GHz bands. After the recent auroral activity, the prospects are worth considering, although it would be surprising if a repeat of the exceptional event of last week were to happen. Nonetheless, stay alert to the Kp index going above 5 and check for activity on the 10, 6, 4 and 2m bands. The event of last week was triggered by three successive days of X-class flares, so for an early ‘heads-up' start with the Sun. The foEs graphs on propquest.co.uk  were interesting for the evening of the Autumn Series contest on the 12th of November. There were some rapid changes in propagation as paths were affected by the F2-layer one minute and Sporadic-E the next.  It is occasionally worth examining the graphs now and again to relate perceived conditions from the radio speaker to actual measurements of the ionosphere. Of course, the data from Dourbes is not necessarily what would have been recorded over the UK, but it gives a good flavour. The takeaway message is that although we think of Sporadic-E as a summer phenomenon, it can play a role outside the main season. Meteor scatter is certainly in the frame this week since the Leonids meteor shower peaks tomorrow, the 17th of November. Since meteors also play a part in Sporadic-E propagation, there is another reason to check the foEs graphs for out-of-season activity. For EME operators, the Moon's declination went negative again on Saturday, the 15th, so Moon window lengths and peak elevation fall accordingly. Path losses are increasing to a maximum at apogee on the 20th of November. 144MHz sky noise is low during all of the coming week except for the whole of Thursday, when the Sun and Moon are close in the sky. And that's all from the propagation team this week.

As part of the RSGB's strategic growth priority, it wants to inspire people from different communities to find out more about amateur radio. That is why the Society has introduced a new category this year called “Reimagination”. If you think your project could be interesting to the maker community, or you have an idea that could encourage people from groups such as Men's Sheds to try amateur radio, this is the category for you. If it is radio-related but motivates non-radio amateurs to find out more, the RSGB welcomes your entry! There are six other categories, which means there really is something for everyone. You must be an RSGB member to enter, but you can live anywhere in the world, as entries will be judged online to allow you to participate and demonstrate your creativity remotely. The deadline for entries is the 1st of March 2026, and you have an opportunity to win a cash prize. For full details of the competition, including the other categories, visit rsgb.org/construction-competition If you're thinking of taking an amateur radio exam before Christmas, be aware that the last date you can take an online exam, either at a club or at home, is Monday, the 22nd of  December. The RSGB Exams Team will, where possible, post out exam results before HQ shuts over Christmas and New Year. Exams will resume on Monday, the 5th of January 2026 and the booking system will be available during the festive season, so you can book exams for January onwards. You can book your exam online at rsgb.org/exampay RSGB Board Director, Ben Lloyd, GW4BML, is delighted to announce Derek Hughes, G7LFC as the new volunteer RSGB Brickworks Champion. The Brickworks scheme consists of 23 tasks that give an insight into different aspects of amateur radio. Derek brings a wealth of knowledge and experience to this role, having previously been involved in the development and running of the Brickworks scheme. He currently serves as Chairman of the Quantum Amateur Radio & Technology Society. Derek is committed to building strong relationships with clubs across the UK, including those already engaged with RSGB initiatives.

Earlier in the week, the 10m band was working very well, with Australia romping into the UK by mid-morning. But later in the week, everything had changed. Solar activity was high with multiple X-class and strong M-class solar flares. At least three coronal mass ejections, or CMEs, were expected to graze or directly hit Earth, sparking strong geomagnetic storms on the 6th and 7th of November. The X-ray flare on the 4th of November was the first seen since June and came from active region 4274 – a large sunspot group which helped push the solar flux index to 147. The Kp index climbed to 6.67 in the early hours of the 6th of November. Later that morning, maximum usable frequencies, or MUFs, were badly affected, with a maximum of 18MHz over a 3,000km path as a strong G3 geomagnetic storm was in progress. So, it looks like good DX on the higher bands may be off the cards for a few days. However, one interesting contact was noted on the CDXC Slack chat group when ZL7/LZIGCC was spotted on 14.005MHz using CW at 10.30 am on Thursday, the 6th. Interestingly, the current solar activity is nearly all in the Sun's northern hemisphere, so are we heading for a second peak in Cycle 25? Next week, NOAA predicts that the solar flux index may decline to the 130 to 145 range. Geomagnetic conditions are predicted to remain unstable until around the 12th of November. With active region 4274 rotating to be more Earth-facing, we may expect more solar activity, such as solar flares and coronal mass ejections, before things quieten down. And now the VHF and up propagation news from G3YLA and G4BAO We are becoming well acquainted with mild, unsettled weather, and as a result, there were plenty of rain scatter options on the GHz bands in the last week. These are likely to continue through the coming week. Tropo is not completely out of the frame in the extreme south and east, albeit fleetingly, but for most of the UK, it is unlikely to be a strong feature. As in recent weeks, a few auroral alerts are coming through, but so far, nothing too dramatic is showing up on the VHF bands. Meteor scatter looks more interesting as we move into mid-November. The Leonids, one of the more important meteor showers in the calendar, peaks just after next weekend on Monday the 17th and Tuesday the 18th, so we should expect to see some increasing activity as we progress through the coming week. The UK Activity Contest events feature 432MHz on Tuesday 11th, when the eastern side of the UK may have one of the fleeting moments of tropo to the east and south. Later in the week, on Thursday the 13th, it's the turn of 50MHz. Conditions look weaker for tropo for the 50MHz UK Activity Contest, but still favour the extreme east of England, if there is any left by then. Meteor scatter or even aurora might come to the rescue for this one. For EME operators, the Moon's declination is at its highest this weekend, ending today, the 9th, so Moon window lengths and peak elevation are also at their greatest. Path losses are now increasing as we passed perigee on the 5th of November. 144MHz sky noise is low and at its lowest midweek. And that's all from the propagation team this week.

The NRC team was recognised “For inspiring all Generations about Amateur Satellites by providing a unique insight into the world of radio communications”. The awards are organised by the British Interplanetary Society. The award was accepted by RSGB General Manager Steve Thomas, M1ACB; NRC Coordinator Martyn Baker, G0GMB; and NRC Volunteers Patrick Wood, 2E0IFB and Brian Hardy, G4BIP. In his acceptance speech, Steve Thomas thanked Martyn and the 65 volunteers for the work that they do in welcoming over 80,000 visitors to the NRC each year. He also said that through the Society's public outreach and STEM activities, it aims to help generate and support future RF engineers who may one day work in the space or related industries. Congratulations to the whole NRC team for this fantastic recognition of the great work you do! Have you ever considered how to engage more girls and women with amateur radio? This question was discussed by a panel of female radio amateurs at the RSGB Convention last month. The group touched on topics including accessibility to in-person activities, support and encouragement, as well as the potential obstacles to attracting more women into amateur radio. The discussion is now available to watch in the RSGB 2025 Convention playlist on the RSGB's YouTube channel via youtube.com/thersgb, and it would be great to use for a club night to start conversations and to help inspire new plans. You can also see the “How to encourage thriving clubs” panel discussion in the same playlist, where four clubs shared the activities that are helping them to gain members. Don't forget to subscribe to the channel to be the first to hear about new videos when they are released. Tomorrow, the 3rd of November, join Graham Somerville, M3ZGS, owner and managing director of DSP noise cancellation specialists bhi Ltd, for November's Tonight@8 webinar.

Using all modes on 1.3 to 3.4GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 30th of October Last weekend saw HF shine as stations took part in the CQ World Wide SSB Contest. Geomagnetic conditions remained settled and DX was plentiful, with contacts possible as far afield as Alaska to the west and China to the east. Given the unsettled conditions we have had recently, it was a welcome break as radio amateurs filled their logs with far-flung DX. As we enter November, we can still expect the fine autumnal conditions that made October so good. However, as the month progresses, we can also anticipate improvements in LF band DX. So keep an eye on the 80 and 40m bands. The solar flux index has declined somewhat and is now standing at 118. This is still enough to get the 10m band humming, but it is a far cry from the 200-plus we saw at sunspot maximum. Nevertheless, get on the bands and work the DX while you can. Two large coronal holes, one in the Sun's northern hemisphere and one in the southern hemisphere, have been the sources of a fast solar wind stream. We may expect more geomagnetic disturbances today, the 2nd. Also, active region 4246 is now coming around the Sun's limb again and could be worth keeping an eye on. It has been emitting solar flares while behind the Sun, so look out for more activity upon its return. For the coming week, NOAA predicts that the solar flux index could increase, perhaps starting the week at around 135 and increasing to 150 by the 9th of November. The first half of the week should be quiet geomagnetically, but we may expect more unsettled geomagnetic conditions around the 7th to the 9th of November, when the Kp index could increase to 5. Expect maximum usable frequencies to be depressed until the Kp index recovers. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of unsettled weather remains the focus for the foreseeable future. Previous model runs had suggested the possibility of high pressure returning by the end of the coming week, but this is no longer the case. The RSGB 144MHz CW Marconi Contest, which ends at 1400UTC today, the 2nd, looks to be under the influence of low pressure rather than any tropo-producing highs. With the unsettled pattern continuing, the optional modes might be rain scatter for the GHz bands, but not tropo. The chances of aurora are there, and after a very auroral-sounding 40m band on Wednesday, the 29th of October, when the Kp index hit 4, we should remain alert to changed conditions on the high HF and VHF bands. However, it probably needs something higher, like a Kp index between 5 and 7, before getting excited about radio effects.  The meteor scatter options look reasonable as we move into November, but the next important shower, the Leonids, doesn't peak until the 17th. We do, however, enter the edge of the stream later in the coming week. A final note of caution is that this unsettled type of weather pattern can produce rapidly developing lows and bring damaging winds to some parts of the country. So, take the opportunity on the quieter days to check that antennas are secure. For EME operators, the Moon's declination is negative and rising, going positive today, the 2nd of November. So, Moon window lengths and peak elevation are both rising. Path losses are still falling as we approach perigee on the 5th of November. 144MHz sky noise is low all week, rising to medium by next weekend. And that's all from the propagation team this week.

It looks like Earth dodged a bullet last week when a large coronal mass ejection, or CME, erupted on the far side of the Sun on Tuesday, the 21st of October. Had that CME been Earth-directed, we could have endured a strong, or possibly an extreme, geomagnetic storm with dazzling displays of aurora. The source of the eruption was possibly sunspot region 4246, which is now past the Sun's west limb. The ACE spacecraft detected high levels of protons streaming past Earth, but they remained below the minor S1 radiation storm threshold. In other news, we have had a quiet geomagnetic week, which has allowed the ionosphere to shine. The solar flux index has been modest, ranging from 130 to 150, but propagation has been aided by improved geomagnetic conditions. During the past week, the 10m band was humming with activity. Lots of stations were preparing for the CQ World Wide SSB Contest, which ends today, the 26th. 8P5A in Barbados has been romping in during the afternoon, as has HZ0YL in Saudi Arabia. Other DX worked last week, according to the CDXC Slack chat group, includes VK9DX on Norfolk Island on 12m SSB; 6O3T in Somalia on 40m CW; and PJ6Y on Saba and St Eustatius using SSB on the 12m band. This last station is a young radio amateurs' DXpedition by the Pacific Island DX Group. Next week, NOAA predicts that the solar flux index will stay in the 140 to 150 range with the Kp index starting the week low but then rising. We may expect a Kp index of 5, or even 6, around the 28th to the 31st of October. Look for auroral conditions and lower maximum usable frequencies during this period. Meanwhile, make the most of the long-range propagation on the higher bands while the Kp index is low. And now the VHF and up propagation news from G3YLA and G4BAO The period of weather up to the end of the week ending the 2nd of November looks distinctly unsettled, with the weather pattern driven by an Atlantic jet stream pointing straight at the British Isles. This will mean that further periods of stormy weather are possible with strong winds and heavy rain. This is not a time to expect much tropo for VHF or UHF, but it is a good period for the GHz bands to explore rain scatter propagation. The foF2 and foEs graphs at propquest.co.uk  have been experiencing some data supply issues recently. It's worth noting that strong jet streams and fast-moving weather systems, as we have now, can bring a chance of out-of-season Sporadic-E. A good example on the evening of Sunday, the 19th of October, can be found if you check the archive tab. This four-hour active period was possibly associated with a slowly advancing jet stream as seen on the Sporadic-E blog tab for that date. Meteor scatter operators had the Orionids, which peaked on the 22nd, to play with last week. The broad zone of activity may continue to provide weakening interest through the coming week. The Kp index has been relatively subdued recently, but the message is once again to continue to monitor for the chance openings by noting when the Kp index reaches 5 or more, or if you start to hear LF CW signals take on a fluttery note. For EME operators, the Moon's declination is at a minimum today, the 26th, so Moon window lengths and peak elevation are both low. Apogee was early on Friday the 24th, so path losses are falling again. 144MHz sky noise rises over the weekend, reaching some 3300K today, the 26th, before falling steadily to low levels the following Friday. And that's all from the propagation team this week.

Hi from the Darling Downs Radio Club for Sunday 26 October, or whatever date it happens to be when you hear this broadcast. I'm John VK4JPM, Secretary of the Club with a heap of good news for this week. Firstly congratulations to highly enthusiastic club member Brad, who last weekend upgraded himself from Shortwave Listener to Foundation Licensee. It might even be that by the time you hear this Brad will be on air as VK4BLL. Our next member meeting is Monday 10 November at regional Scouts HQ in Victory Street Newtown. EMR is the topic - that's Electro Magnetic Radiation, the stuff that happens when charged particles are accelerated and put to some hopefully good use. Beyond the need to do something useful with the radiation comes the requirement to understand how to play safe. Too little EMR and you won't be able to communicate with anyone. But when there's too much EMR you might well have problems ranging from annoyed neighbours to seriously dangerous health issues. We're being joined by John VK4JBE who will introduce an EMR Safety Site Management Book, designed to help amateurs record all the information necessary to use the WIA and RSGB tools, and ensure that you are complying with the requirements of your ACMA license. John has taken other clubs through this topic and the feedback has been very strongly positive... rather like some of the EMR that he will discuss. That's on Monday 10 November from 1900 AEST and held in person at Victory Street, and also by telepresence. All the detail is on the website - go to the home page which is ddrci.org.au and wait for the scroller to cycle around to the item for the meeting. And if you have questions, send a note to secretary@ddrci.org.au so that we can get you answers. Coming up later in the year we're looking at a Foxhunt, a BBQ end-of-year lunch, and a meeting devoted to getting the best out of the ridiculously cheap Chinese handhelds that everyone seems to have these days. We'd love to know your thoughts on these ideas, and don't be afraid to tell us. Secretary@ddrci.org.au. Oh, and there's still time to renew your club membership if you haven't done that yet. Just go to the home page and click the big red button that says "Join our club: click here". It can't be simpler than that. Until next week, thanks for tuning in and all the best from the Darling Downs Radio Club. This is Allan VK4HIT with news from Ipswich and District Radio Club. Last weekend on Saturday October 18 the club hosted a major JOTA/JOTI event at the Denmark Hill clubhouse. A total of 153 enthusiastic young people turned up across the day. Of this number there were 40 Guides, 80 Joeys and Cubs and 33 Scouts and Venturers. The day ran from 9am to 8pm with Joeys and Guides present before 1pm and Scouts and Venturers after 3pm. Various activities included orienteering (using handhelds) in the bush adjacent to the clubhouse (Denmark Hill Conservation Park), electronic kit building, 20 computers for JOTI chats, as well as Minecraft, and the obligatory contacts made on VHF via All Star and HF. The 2025 JOTA/JOTI event was supported by eight members from the Ipswich and District Radio Club. It was a great day, only interrupted by a late storm which did its best to try and launch a gazebo in the direction of Toowoomba! Reporting from Ipswich this is Allan, VK4HIT. From Kevin VK4UH here, President of the Brisbane VHF Group and Convener of the QTech 2025 conference, to be held in Brisbane. The two-day conference will run over the weekend of the 1st and 2nd of November and is being held at the conference facilities of the Kedron Wavell RSL in Chermside, one of Brisbane's northern suburbs.

GB2RS News Sunday, the 19th of October 2025 The news headlines: · Ofcom implements Phases 2 and 3 of the amateur radio licence review · Share your feedback on the RSGB's 2025 Convention · The RSGB releases a video to help members make the most of its mobile app Following the introduction of the current amateur licensing framework in February 2024, Ofcom has now implemented most of the remaining changes associated with Phases 2 and 3. Ofcom updates its online Licensing Portal to accommodate applications for new M8 and M9 Intermediate callsigns, more flexible special event callsigns, and other changes, including easier revalidation. It also starts a gradual move to single personal call signs. For example, the revocation of lower licence callsigns is automatically triggered by a new application. Both Ofcom and the RSGB have released guidance for radio amateurs about these changes. You can see both documents by going to rsgb.org/guidance-resources. Please also note that the Ofcom licensing portal now requires longer and stronger passwords, so you may need to reset yours first before you can make any changes. The RSGB's 2025 Convention took place last weekend and brought together hundreds in person, as well as many more from across the globe who watched via the livestream. The Society is already receiving an overwhelming amount of positive feedback. If you did attend the Convention and haven't yet completed the feedback form, please go to rsgb.org/feedback  and share your thoughts. If you were unable to attend in person and watched the livestream, the RSGB would also love to hear your feedback. Please visit rsgb.org/livestream-feedback  and let the team know what you thought of the online event. The feedback forms will be closed at the end of October. The livestreams for both days will remain available for everyone to watch on the Society's YouTube channel via youtube.com/thersgb. Whether you want to sit back, relax and enjoy the whole programme or use the timestamps to watch a particular topic, you'll find something to enjoy. As well as talks from the weekend, you'll find exclusive interviews and pre-recorded videos. The RSGB has released a short video explaining how to get the most out of its new mobile app. The Society has received great feedback about the new app and wants to ensure everyone enjoys the full functionality.

On Thursday the 23rd, the RSGB Autumn Series SSB Contest runs from 1900 to 2030 UTC. Using SSB on the 80m band, the exchange is signal report and serial number. The Worked All Germany Contest started at 1500 UTC yesterday, the 18th, and ends at 1500 UTC today, the 19th of October. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. The CQ World Wide DX SSB Contest starts at 0000UTC on Saturday, the 25th and runs until 2359 UTC on Sunday, the 26th of October. Using SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 16th of October Conditions over the past week have been reasonable with a relatively high solar flux and lower Kp indices. This resulted in a maximum usable frequency, or MUF, over a 3,000km path, in excess of 35MHz. This is just what October was meant to be like! But all good things come to an end and there are a few flies in the ointment coming up. On the 14th, the latest coronal mass ejection, or CME, tracking model from NOAA and the Space Weather Prediction Testbed showed three weak CMEs possibly passing Earth over the next few days.  Although none of them is expected to deliver a large impact to the Earth's geomagnetic field, a combined passage could generate minor G1 to isolated moderate G2 geomagnetic storming.  We are now well and truly into autumn and, with a daytime critical frequency of more than 9 to 10MHz, the 40m band is ideal for QSOs around the UK during the daylight hours. At night, the critical frequency is generally around 5MHz in the early part of the evening, dropping to 3.5 to 3.6MHz as the night progresses. This means that the 80m band is remaining open around the UK for longer, but it may fade out, perhaps towards midnight. October is a great month for HF with the potential for worldwide openings on the higher bands. Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range. Unsettled geomagnetic conditions with reduced MUFs are forecast for the 20th of October and then again on the 25th and 26th, when the Kp index could hit 5. Incidentally, these are the same dates as the CQ Worldwide SSB contest. And now the VHF and up propagation news from G3YLA and G4BAO This next period offers a marked contrast to our recent spell of Tropo weather under high pressure. Today, the 19th, sees a change to a much more unsettled weather type with rain, areas of low pressure, strong winds and showers. This will take Tropo off the agenda for the coming week, and its replacement is likely to be rain scatter for those on the GHz bands. There is no point in trying to time each individual low and front coming through this far ahead, and there is no real scope for any significant intervening areas of high pressure between the lows. So, there is no hint of Tropo next week. The recent solar conditions have again suggested that it's worth looking at the Kp index for signs of aurora, should it go above 5. Next, a few words about meteor scatter, which is gearing up for the Orionids, peaking on Tuesday, the 21st. However, they can have a broad spread with a minor peak preceding the main event. Either way, it's worth checking up on meteor scatter techniques and frequencies before the shower, rather than wondering what to do when it happens. For EME operators, the Moon's declination is falling again and becomes negative today, the 19th, so Moon window lengths and peak elevation follow suit by falling. Path losses are still rising as we approach apogee early on the morning of the 24th.  As we move through 2026, we reach a ‘sweet spot' in June where perigee and the highest declination coincide. This means the lowest path losses occur when we have the longest Moon windows. This cyclic event last occurred in 2018 and will not occur again until 2035.  144MHz sky noise starts the week low until Tuesday, the 21st, when the Sun and Moon are close in the sky. This brings noise problems for Yagi-type antennas with their high beam width. After that, the noise rises too high again for the weekend beginning the 25th of October. And that's all from the propagation team this week.

This show has been flagged as Clean by the host. Hello again. this is Trey. This is part 2 in my Cheap Yellow Display (CYD) Project series. You can find Part 1 in episode 4472 . We previously left our handy hero learning about the technology of the CYD, but without a compelling reason to begin using one. As we rejoin the topic, it was Winter Field Day 2025 (Jan 25 & 26, 2025). Winter Field Day is an annual event where amateur radio operators from around the world gather some portable radio equipment and setup somewhere away from their normal base of operations. It is designed to encourage operators to practice their emergency preparedness skills in unfavorable weather. Usually, they will run their equipment using batteries or generators. I chose this day because I knew there would be a good amount of radio traffic. I had just finished tuning my first handmade inverted-V dipole antenna for use on the 10 meter amateur radio bands. These span 28 MHz to 29.700 MHz. I had the antenna connected to a 10 meter transceiver to listen in on the radio traffic. Yes, I will include pictures of the antenna in the show notes. Scanning through the lower end of the band resulted in receiving a number of very strong continuous wave signals. Continuous wave, is abbreviated CW in amateur radio circles, and it stands for morse code signals transmitted over radio frequencies. The tones indicating dots and dashes of Morse code were clearly audible through the radio's speaker. "WAIT! STOP! Time out!!" I can hear you shouting as you listen. "This is supposed to be a discussion of the ESP32 CYD. What does this have to do with amateur radio?" You are absolutely right. Now hold your horses and we will get there. I barely learned Morse code as a child, and I used it a bit as an aviator in the '90s (while always being able to reference a visual representation of the Morse beside the actual letters). Thus, I never became proficient. Shortly after Winter Field Day 2025, I began taking lessons on Morse code, with the goal of becoming proficient at both sending and receiving at around 20 words per minute. This training may be a topic for another episode in a different series, as my journey advances. Scanning further up the band, I also identified some digital transmissions (Probably FT-8) and many voice transmissions. The antenna was working, at least for receiving. For a little back history, I have held an amateur radio license since 2016, and quickly progressed all the way to an Extra Class, giving me permission to use all of the amateur radio frequencies allowed within the United States in the High Frequency (HF), Very High Frequency (VHF), and Ultra High Frequency (UHF) bands. However, to this point, I have only operated in the VHF and UHF bands, and have done so using mobile and handheld transceivers. I inherited some HF equipment from a close friend who went silent key in 2023, and I was only now trying to use it. You can learn more about my friend, and about the term "Silent Key" in episode HPR3922 https://www.hackerpublicradio.org/eps/hpr3922/index.html ) On field day, there was far too much traffic, and it was too intimidating for me to make my first attempt at transmitting on the HF bands. This would have to wait until later. But I did need to determine how well my antenna would transmit. I began to ponder my options. I really did not want to talk to anyone until I had listened to more QSOs and I could implement proper practices. The term QSO the amateur radio term for radio conversations. I also have no interest in digital modes (yet). I like the simplicity of voice and CW. There I am, back at Morse code again. What if there was a way that I could transmit a signal in Morse code and get reliable feedback on signal propagation, without the need to try to reply to any responses? It would need to be an accurate, repeatable, properly structured and timed Morse code transmission, more than my training (at that point, or even this point) could accomplish. This was something to think about. And think about. And think about... Tune in to the next episode in the series to learn where these thoughts led me, and how all this relates to my CYD project. Provide feedback on this episode.

Foundations of Amateur Radio The other day I went on my first POTA or Parks On The Air adventure, this time I was on my own. If you recall, my power company announced yet another planned network outage and I felt that I could use this time without electricity to my benefit, for a change. As is traditional, I did all the prior planning to prevent pretty poor performance. I made a list, checked that all the items on the list were in my kit, packed the kit days before, put it all ready to go in the hallway the night before, packed the car on the day and set out on my adventure. I will confess that I was slightly more sweaty than anticipated when I set off because the umbrella in the boot of my car has a nasty and recurring habit of getting in the way, specifically it stops things from getting pushed right to the full depth of the boot. Mind you, it wasn't until I started getting agitated that I realised that it wasn't the umbrella's fault entirely this time, since as it turns out, the folding chair that I was attempting to jam in place doesn't actually fit longways into the boot. Anyhoo, I set off and visited the local petrol station. I was not prepared for a customer to spend 15 minutes dribbling the last bit of diesel into their pretend Sports Utility Vehicle, but he looked like he was up for a fight, so I smiled sweetly and waited for him to pay and move his box on wheels. After paying for my own fuel and driving off, the pressure in my bladder had gotten beyond the "cross your legs and hope for the best" stages and I swiftly made my way to the nearest shopping complex where a local pharmacist helpfully told me that there were no toilets in the building and that the local hotel or fast food joint were the place to relieve the pressure. One problem .. they were both closed. At this point I was in pain, and discovered that I couldn't read the screen on my mobile phone in the lovely sunlight, because it was set to battery saving mode, since my charger was at home where the power was out. After disabling the battery saving mode I opened the local public toilet map shortcut on my phone, and discovered that fortunately the shortcut still worked, opening up my default browser, which suddenly didn't want to display a map. Copied the URL to another browser, still in pain, finally a map. Click on the nearest icon and it navigates me there from Darwin, or over 4,000 km from where I actually am. Luckily it has the GPS location which I copy and then paste into my mapping app, and I can finally navigate to the nearest toilet. Several comment worthy navigation moves later, I drive into the car park, lock the car, painfully shuffle to the building, do my business in the very clean facilities and then decide that I should just stop, sit, and take a breath. So, I get in the car and discover that my partner was right when they heaped scorn on our newly acquired thermos cup. It really does hurt your nose when you try to drink from it and the sharp edges in your mouth do nothing to make the experience joyful. Meanwhile there's some trucks moving around in the car park and a guy walks up to the car to ask me if I can move because they want to move a third, or was it forth, truck into the space. I swallow my sip of restorative coffee, wipe the now wet bridge of my nose, and move the car, only to be blocked from leaving the exit thanks to the slowest reversing truck I've ever encountered, one who then proceeds to sit at the next intersection for five minutes without indicating where it was going. Are we having fun yet? I finally made my way to the main road where I attempt to calm my nerves with the help of a Morse code edition of my podcast. It's been the only exposure I've had to Morse for way too long. This accompanies me to my first destination, breakfast. I'm going to skip past the drivers in the centre lane driving at 10 km per hour below the posted speed limit, or the ones who think that jumping out of a side street in front of you is normal and safe driving practice. At every traffic light I celebrate the pause with a sip from my coffee and a furtive wipe of my nose which is being assaulted by the lid of the cup. I arrive at my breakfast destination and fear the worst. Their car park is almost empty. I've never seen it this quiet and I didn't check to confirm that they were open, or not. I look at my map application and remember to turn my phone back to battery saving mode. According to the Internet, my cafe is open, so I cross my fingers and get out of the car. To my delight, they are absolutely open, make me a lovely breakfast and provide the needful for lunch too .. I have a big day planned after all. After enjoying breakfast and hot chocolate, with two marshmallows, I get back in the car and navigate to my planned set-up location. As I drive into the park I notice something that I hadn't the last time I was here. I'm descending, as-in, the deeper into the park I go, the more I go downhill. That in and of itself isn't a cause for concern, were it not for the fact that the local repeaters are on the hilltops that overlook the city and I'm several hills inland and travelling into a valley. I'm keeping my eyes open for side roads and alternatives, but gamely proceed to the formal entrance of the park, where I pay my $17 to have a car with a maximum of 12 passengers enter the National Park. I drive to the location I have planned and discover that there's a car park quite close to the gazebo I've earmarked, so I park there. I figure that before I get all set-up in the gazebo for a day of radio, I should first check what I can learn from where I'm parked, especially since I'll need to pull the gear out of the car either way. Before I get out of the car, I attempt to mark my actual location on the map, only to discover that there's no mobile phone coverage, so much for using Echolink as a fallback. I pull out the folding table which neatly fits next to the car, dig out the coax from the boot and lead it out the passenger door. The other end is connected to the boot-lip mount that has been there for years. In case of failure I did bring a magnetic base, but I'm optimistic. I remove the HF and VHF multi-band antennas from their storage spot, taped to the driver side rear passenger roof grab handle and pull out the previously errant folding chair. All is going well. I pull out the spare coax and my anxiety spikes a little, this is what I think might be what causes me to come unstuck. It's a 10 meter or so length of coax, it's untested, terminated with BNC and I'm concerned that I didn't bring enough adaptors beyond the BNC to PL259 and the SO239 barrel I packed hastily the night before. I push away my fear, since I'm not needing this right now and continue to unpack the radio, noticing that to my immense relief, the knobs are still attached, set it all up, pull the power cable from the 12 Volt, 80 Amp hour AGM Deep Cycle battery, "ideal for 4WD, caravan and camping trailers", which I bought four years ago to power my dash cams and radio. It's automatically charged by a 360 Watt DC to DC converter that's connected to the alternator in the car - because I don't want my dash cams, or radio for that matter, to stop me from starting the car. Ask me how I know. The power leads are long enough to make it out of the boot and I connect the inline volt meter to the battery, 12.6 Volt, the same as what I saw when I checked it a week earlier. I mount the VHF multi-band antenna, connect it to the radio after pulling out the N-Type to PL259 adaptor which is on the list and part of the standard kit. I take a breath and turn on my radio. Tune to the local repeater frequency and hit the PTT. The radio is set to 5 Watts and I'm hoping to hear the repeater tone. Nothing. I check all the repeaters in my radio, about seven of them, none of them do anything. Then .. I hear a click. I've been "on-air" for all of three minutes. I notice the radio is turned off. I've seen this before, sometimes stray RF gets into something and causes the radio to stop. I turn it back on and notice the voltage on the display of the radio, 9.65 Volts. That .. is .. not .. good. I check the inline volt meter, it doesn't even display anything. I turn off the radio to save what little power I have. I take a moment to consider and attach the HF antenna, hoping that I can run the radio for a few seconds to check the local 10m repeater. All is good to go, turn on the radio and it won't even turn on, just flickering on and off. I feel like I want to cry, but there doesn't seem to be any point. I pack everything back up, the water, my hat, the radio, the coax, the antennas, the table, the chair, put it all back in where it came from, even the sandwich I was going to have for lunch. After slowly reversing out of the car bay, looking carefully at the ground to make sure I didn't leave anything behind, I make my way out of the park. I've been there for a grand total of 29 minutes. I briefly entertain the idea of going to the nearest electronics store and spending $50 on a small battery, but I don't actually have a working charger, and spending several hundred dollars on a charger and battery is not really in my budget at the moment. Whilst I was driving home I got a notification that the power was out at my QTH. I got home 52 minutes after the power went out. It stayed off for the next six hours. So much for being productive. My friend Charles NK8O, tells me that his first few activations were a bust. He's a Sapphire POTA activator with 609 activations across 372 parks, so, there's hope for me yet. In looking back at this adventure, I was planning for failure. I'd thought through all the different permutations of what might happen. Not for one moment did I consider that my battery might be a single point of failure. That said, there were hints that not all was well. The 12.6 Volts was one hint, the fact that my dash cams have been acting up was another. I had been on the hunt for a battery monitor for the past two years to discover precisely what was going on, but I haven't found one that doesn't require a specific app that needs to know where you are or what's in your diary, so I put it out of my mind. As it happens, that was where I made my rookie mistake. Mind you, part of me knows that I don't have another battery anyway, so it really didn't matter if the battery was faulty or not. Either way, I wasn't going to connect my radio to my car battery, I learned that lesson well over a decade ago. I'm back to the drawing board. It's unlikely we'll use that location to activate for the 750th edition of F-troop, but when I get my power situation sorted out, it's still a lovely place to get on-air and make some noise.

Thank you to everyone who has responded to the RSGB's call for Jamboree on the Air participation. Samuel McCutchion, M0UEL, is the RSGB Youth Champion for Scouts, Cadets and Guides and has compiled a list of Scouting groups that are involved with the annual event. To view the list, go to rsgb.org/jota  and select the ‘JOTA Stations on the Air' link on the right-hand side of the page. If you are planning to get involved with JOTA and would like to be added to the list, please get in touch via youthchampion.scouts@rsgb.org.uk  with a summary of your station name, callsign and any other relevant information. The RSGB would love to see your photos of Scouts getting involved with JOTA, so tag @theRSGB and also use #JOTAJOTI to be involved in the conversation on social media. If you're not involved with a JOTA station, do listen out for them on the air and encourage the young operators. This year's event is taking place between the 17th and 19th of October. Volunteers at the RSGB National Radio Centre had a particularly busy weekend at the end of September. It was 1940s weekend at Bletchley Park for which the Centre set up the GB1SOE station, and over the weekend, RSGB volunteers welcomed almost 1,100 visitors through the doors. If you'd like to be part of this engaging and motivated team, the NRC Coordinator is currently looking for a volunteer specifically to join the Friday team. If you'd like to find out more about this role, email Martyn Baker, G0GMB via nrc.support@rsgb.org.uk RAF Air Cadets Exercise Blue Ham will take place on the 60m band from 0700 to 1600UTC over the weekend of the 18th and 19th of October. To operate, you must be a Full licence holder. More details can be found on the alphacharlie.org.uk  website. The RSGB wishes to record, with sadness, the passing of GB2RS Newsreader Peter Valentine, G0NQZ, at the grand age of 101. Age was no barrier to Peter. At a mere 96, he walked 96 miles for his local hospital charity, and he was still broadcasting GB2RS from Eastbourne in his 100th year. He was described by a fellow Newsreader as a true ambassador for amateur radio. Peter had a wonderfully distinctive voice on the air, and for many years, he also read a talking newspaper for the blind. Our thoughts are with Peter's wife, Heather and family. Please send details of all your news and events to radcom@rsgb.org.uk. The deadline for submissions is 10 am on Thursdays before the Sunday broadcast each week.  And now for details of rallies and events Today, the 12th of October, the Autumn Dartmoor Radio Club Rally is taking place at Yelverton War Memorial Hall, Meavy Lane, Yelverton.

The Worked All Germany Contest runs from 1500 UTC on Saturday, the 18th, to 1500 UTC on Sunday, the 19th of October. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 8th of October We finally got rid of the high-speed solar wind stream, which caused havoc on the HF bands. But we are not out of the woods yet! Last week saw the Kp index hit 6.67 on the 2nd of October, and it was often up around 4 or more. Even though the Kp index eventually reduced, the ionosphere took its time to recover, and things were not back to near normal until Tuesday, the 7th. Meanwhile, the solar flux index decreased to 131 by the 8th, so the HF bands were hardly humming by this time. DX on the 10m band was hard to find. Openings to Europe were commonplace, but longer paths were not so good, with only weak North American stations being heard later in the day. A minor G1 geomagnetic storm watch was in effect for 48 hours from the 7th of October, when at least one faint coronal mass ejection was predicted to pass the Earth. Only minor C-class solar flares occurred during the week, but that didn't help too much. CDXC members were reporting DX, such as V85T in Brunei on 15m and A52G in Bhutan on 20m – both using CW. However, there was not much to work on the higher bands. Southerly paths were a little better with 5X2I in Uganda reported on the 17m band using FT8. Next week, NOAA predicts that the solar flux index will be in the range of 130 to 140, but it is also predicting geomagnetic disturbances today, the 12th. After that, the Sun may quieten a little with a maximum Kp index of 2 for the rest of the coming week before more geomagnetic disturbances. The Kp index is forecast to be 4 or 5 during the weekend of the 18th and 19th. And now the VHF and up propagation news from G3YLA and G4BAO The coming week is dominated by high pressure, either over the UK or near enough to influence the propagation and provide a prolonged period of Tropo weather. It's probably worth mentioning a few ground rules about Tropo operating. Firstly, large areas of high pressure can produce widespread lift conditions due to the strength of the elevated temperature inversion 1 to 1.5km above the ground. The longer the high lasts, the lower this descends, so limiting the maximum distance across the centre of the high. Try beaming around the edge rather than across the centre. Secondly, there may be surface temperature inversions at night or in foggy weather, and these will provide temporary enhancements. Thirdly, the clue for a good ‘radio' temperature inversion is the presence of fog or layers of cloud, which give a better moisture contrast and ducting prospects. One last point. Try other modes like SSB or CW rather than sticking to repeaters which can get very crowded in lift conditions. There is no rain scatter in the frame this week, and the Draconids meteor shower has just passed, so back to random activity on that front. On the 8th of October, the Sporadic-E graphs at propquest.co.uk  showed that there had been occasional spikes up to 5MHz or so. This may liven up the 10m band if we get any more. There have been a few weak auroral events, but nothing too exciting. For EME operators, the Moon's declination is still increasing, reaching its peak today, the 12th, so long Moon windows and high peak elevation continue. Path losses are rising again after perigee on the 8th. 144MHz Sky noise will be moderate to low for the coming week. And that's all from the propagation team this week.

Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 2nd of October 2025 Last week was characterised by very unsettled geomagnetic conditions with a Kp index that reached 7.33 on the 30th of September and was often above 5. This is not good for HF propagation! But what caused this? A high-speed solar wind stream at around 750 kilometres per second, coupled with the Bz component of the Sun's magnetic field pointing south, led to the disruption. But there didn't seem to be any particular solar event that triggered the high-speed solar wind stream. The Russell-McPherron effect is probably to blame. This is a phenomenon where the alignment of the Earth's and the Sun's magnetic fields, during the equinoxes around March and September, allows charged particles from the solar wind to more easily penetrate the Earth's magnetosphere. This enhanced connection leads to more intense geomagnetic storms and increased aurora activity as the Bz aligns favourably with the Earth's magnetic field at these times. This may pass as we get further into October. As a result of the geomagnetic storm, maximum usable frequencies, or MUFs, have often been lower than normal. A quick listen on 28MHz on Wednesday, the 1st of October, confirmed the poor conditions. It's a shame, as October is normally a fantastic month for HF DX. The solar flux index peaked at 187 on the 30th of September, having been above 170 since the 28th of September. Next week, NOAA predicts that the solar flux index will remain above 150 to 160 all week. The good news is that geomagnetic conditions are forecast to improve, with a maximum Kp index of 3. If that comes to pass, we can expect HF to be better after a day or two, and we might be able to make the most of the autumnal conditions for DX. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of unsettled weather, mainly over northern areas, is typical of the season, but it's also common to find high pressure passing by in between the deeper lows. In the current pattern, the highs are mainly for the southern half of Britain. This will bring some good Tropo conditions at times for the VHF and UHF bands.  As we head into autumn, these lifts may linger through much of the morning on some days before the temperature rise breaks down any temperature inversion. A good clue is that it's usually over when the overnight fog clears. On the other hand, there will probably be some good rain scatter opportunities on the GHz bands as the active lows push fronts across the country, especially in the north. There are signs that we may return to high pressure over the country during the RSGB 2025 Convention weekend from the 10th to the 12th of October. We have a meteor shower to play with during the coming week. The Draconids peak on Wednesday, the 8th of October, but the shower stream is spread over the whole of the week. Lastly, there have been some reasonable auroral events recently, so, as usual, keep a watch on the Kp index going over 5 since, as we said earlier, these autumn months are very much favoured for auroral activity. For EME operators, the Moon's declination is increasing and goes positive tomorrow, the 6th, so lengthening Moon windows and increasing peak elevation is the story for the coming week. Path losses continue to fall as we approach perigee on the 8th of October. 144MHz sky noise will be low for much of the next seven days. And that's all from the propagation team this week.

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. If you're wondering what you can do with your LoRa tracker now that the RSGB challenge has finished, go to rsgb.org/lora-balloon for a handy guide on how you can continue the fun.

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.

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. You will be able to buy a Convention ticket on the door but not at the reduced rate that is available now. Your ticket will give you access to numerous presentations including two on the funding available to interesting and innovative amateur radio projects. The RSGB Legacy Fund supports a wide range of projects and Legacy Committee Chair, Richard Horton, G4AOJ will give some recent examples that have been allocated funding. He'll also talk you through how the application and approval process works. The California-based Amateur Radio Digital Communications foundation has its roots in amateur radio and the technology of internet communication. Steve Bunting, M0BPQ and Chris Smith, G1FEF will give an overview of ARDC's grants which are also open to international charities, non-profits, schools and universities. If you're thinking of a new project that would benefit amateur radio or help to bring it to new audiences, these are two presentations you won't want to miss! Find details on these and all the other Convention presentations via rsgb.org/convention  You'll also find a new web page outlining what else is happening during the weekend. If you're attending the Convention for the first time, then pop along to the RSGB's new ‘welcome desk' on the Friday evening from 6.30pm to 7.30pm and then from 8pm to 9pm. The desk is aimed at first-time or solo attendees, although anyone can come and say hello. A member of the RSGB HQ team and other RSGB volunteers will be on hand to greet you and introduce you to like-minded people, and act as a familiar face throughout the weekend if you need any help. The RSGB Convention takes place between the 10th and 12th of October. Every radio amateur knows that it is important to identify yourself clearly when operating. This includes the mandatory use of a Regional Secondary Locator, or RSL, if you hold an Intermediate callsign in the 2-series. For example, your callsign would start with 2E0 if you're in England or 2M0 if you're operating in Scotland. This mandatory use of the RSL is shown in the Ofcom licence conditions. You can find a link to that document on the RSGB licence updates web page at rsgb.org/licence-review Calling all young radio enthusiasts wherever you are in the world! The RSGB Outreach Team is thrilled to launch its first official DMR Youth Net.

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 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.

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.

GB2RS News Sunday, the 7th of September 2025 The news headlines: WRTC, QO-100 and how to have a thriving club – be part of these discussions at the RSGB Convention Listen out for special GB2RS broadcasts from the NRC as part of GB70RS celebrations The RSGB replies to the latest Ofcom 2.3GHz consultation The World Radiosport Team Championship 2026 takes place in the United Kingdom, and Mark Haynes, M0DXR, is the Chairman of the Organising Committee. Join Mark at the RSGB Convention on Saturday, the 11th of October, to find out how the team is progressing for the event, which will host 100 operators from all around the world. If operating via QO-100 is something you would like to try, join Paulo, F5VMJ/G0MUW, as he shares his experience of the mode, including his home setup and how to go portable. In a new-style presentation for this year, representatives from four amateur radio clubs will be joining a panel at the Convention. They will each discuss different aspects of their club activities that are contributing to the club's success and growth. Join the conversation, share your thoughts and experience, and be inspired. If you'd like to get practical during the Convention weekend, there are a variety of opportunities, including three workshops. The majority of workshop tickets are now sold, so book now to avoid disappointment. With only five weeks until the Society's annual Convention, secure your place via rsgb.org/convention. 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. Two exciting activities have been developed for you to get involved with. Whether you are a complete beginner or an experienced coder, you can get stuck into both the Python Pocket Morse activity and the LoRa high-altitude balloon challenge. Don't forget to let the Society know how you get on. Share your story and photos with the RSGB Communications Team via comms@rsgb.org.uk RSGB Board Chair Dr Stewart Bryant, G3YSX, has announced that Peter Bowyer, G4MJS, is stepping down from his role as RSGB Director due to an unexpected and significant increase in his professional duties.

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.

Using all modes on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. On Sunday the 7th, the Worked All Britain 2m SSB Contest runs from 1000 to 1400 UTC. Using SSB on the 2m band, the exchange is signal report, serial number and Worked All Britain Square. This year, the QRO and QRP contests are combined. The full rules are available on the Worked All Britain website. On Sunday the 7th, the 5th RSGB 144MHz Backpackers Contest runs from 1100 to 1500 UTC. Using all modes on the 2m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 28th of 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.

Now here's your hosts, Allen Hall, Joel Saxon, Phil Totaro, and Rosemary Barnes.  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,

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.

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.

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.

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. He donated his remains to that Study and to Washington University School of Medicine. -"William “Bill” Sabastian Salfen was born 16-Sept 1922 in Dardenne, St. Charles County Missouri. -His parents were Sebastian J "Boss" Salfen (1886–1961) and Josephine "Phinnie" Sattler (1893–1974). -He had one brother, Harold. William attended St. Charles High School. According to the Federal Census, the family lived on Main Street in O’Fallon in 1940. -William Salfen joined the Army Air Corps in June 1942. In September 1942, Bill completed a 12-week Flight Training course at Missouri University. " -"On 27-Jun 1943, William arrived at Corsicana Field from the San Antonio Aviation Cadet Center. -William Received his Army Air Corps Silver Wings and 2nd Lieutenant commission at Frederick Field in Oklahoma on 11-Jan 1944. -William Salfen was assigned to the 44th Bomb Group, 506th Bomber Squadron (Heavy) of the 8th Air Force in England. -They were the first 8th Air Force Bomb Group to be equipped with B-24 Liberators. -On 7-Oct 1944, William Salfen’s plane was damaged, and the crew was forced to bailout. The U.S. Army's 44th Bomber Group Crash Report of the bombing states that his aircraft, #789, was last seen in vicinity of Kassel at 1224 hours. #1 and #2 engines had been knocked out by flak and it fell out of formation, under control. It was last heard from at approximately 1239 hours calling on VHF for fighter support." The following is a first-hand report from Lt. Donald B. Iden, the Co-Pilot: “Our plane was nicknamed "LAKANOOKIE", model B-24 (serial #42-50789), and it took flak which disrupted two of its engines. The bombing raid was on a German tank factory. 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.

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

Becoming Mode Agile

Foundations of Amateur Radio

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.

Down the rabbit hole he went into the land of SDR, or Software Defined Radio. The magical crossection of abandonware, software geek passion projects, and radio nerdism left him with a few more nuggets to add to his Signals Intelligence repetoire, and will make for a chaotic (but hopefully informative) show and tell. More info at https://www.rtl-sdr.com/Matter of Facts is now live-streaming our podcast on our YouTube channel, Facebook page, and Rumble.

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

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
