The Worked All Europe DX CW Contest starts at 0000UTC on Saturday, the 9th and ends at 2359UTC on Sunday, the 10th of August. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 31st of July 2025 Last week was very much a repeat performance of the week before. We had relatively calm geomagnetic conditions and few solar flares to contend with. The only flares were minor C-class events. The Kp index never got above 3, and the solar flux index was in the 140s to 150s. The F2-layer maximum usable frequency over a 3,000km path rose to 21MHz but didn't get much higher, which is normal for the summer period. A team from Norfolk Amateur Radio Club was active as GM0FRT/P from the Shetland Islands for the IOTA contest. They were workable from JO02NN on 14 and 21MHz for much of the contest period. The distance to Shetland from central UK is about 887km, or 551 miles. Given the distance involved, the 21MHz openings were probably Sporadic-E, but they were loud for hours on end. Other DX worked last week included T30TTT from Western Kiribati on the 10m band using FT8 over the North Pole. 9M8A from East Malaysia was also on the 10m band using FT8. XW4KV from Laos was on the 12m band operating FT8. 3B9SP on Rodriguez Island put in an appearance on the 17 and 12m bands using FT8. The station was also worked using CW on the 40, 30, 20 and 15m bands. That's not a bad haul for summer DX and if the Kp index can stay low, we could get similar next week. Speaking of which, NOAA predicts that the solar flux index will be in the range of 150 to 160 next week. Unsettled geomagnetic conditions are forecast for the period of the 7th to the 14th of August, with a maximum predicted Kp index of 5. And finally, there is talk of a possible large sunspot group on the far side of the Sun. The region in question belongs to a cluster of spots, including AR 4136, 4139 and 4143, last seen earlier this month. Solar rotation will carry what remains of these regions back into view next week. So, keep an eye on solarham.com  for up-to-date details. And now the VHF and up propagation news from G3YLA and G4BAO The slightly unsettled theme to the weather will remain into next week, although there are signs that high pressure will try to return in the middle of the week for a time. Models disagree on details, with some bringing another thundery low into the south later. This means that there will be some Tropo at times and, in high summer, this tends to be generally strongest around the coasts. To benefit from these conditions inland it's better to wait for night cooling. As usual with thundery weather, it's a good chance to listen for rain scatter on the GHz bands. Another mode that still deserves attention is meteor scatter. Look out for the early stirrings of the August Perseids, which peak around the 12th and 13th of the month.  Surprisingly, Aurora is staying in the limelight. Periodic alerts are suggesting it's worth turning your VHF beams north if you notice any signs of fluttery HF signals or discover the Kp index has risen to 5 or above. If auroral activity appears on the 10 or 6m bands, then check the higher bands as the event develops. Sporadic-E is now in its occasional phase as we move into August. It is less common than in June, but still worth considering. Check the usual cluster maps and Propquest to see how the day is unfolding. Moon declination is negative, falling to a minimum on Tuesday, the 5th. So, Moon windows and peak elevation will also decline. Path losses reached maximum at apogee on the 1st of August, so are starting to fall again. 144MHz sky noise starts the coming week moderately, but will rise to high levels by Monday. It will reach over 300 Kelvin by Tuesday evening before falling back. And that's all from the propagation team this week.

There are many ham radio myths, and let's take a look at them and see if we can bust some of them. Are there only grumpy old men? Is CW better than FT8? Is [insert mode here] killing ham radio? This and much more.Also, it's July, so expect more tangents and stuff off topic than usual.TEHRS is:@labcat73 @LB4FH @LB0FI @LB5JJ @AH6UN_OE4JHW #amateurradio #hamradio #amateurfunk

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

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 24th of July It was a bit of a mixed bag last week. The first half saw settled geomagnetic conditions, but from the 22nd of July, we had a disturbance thanks to output from a solar coronal hole. This saw the Kp index rise to 4.67 and ultimately 5. The stream from the Sun reached around 730 kilometres per second, while the Bz component of the interplanetary magnetic field, or IMF, was mostly neutral with a few brief periods when it pointed slightly south. So, its effects were perhaps not as bad as they could have been. The coronal hole has now rotated out of view, so we may have some better days. Meanwhile, the solar flux index has been in the range of 140 to 150, which is pretty good. There were no M-class or higher solar flares over the past week, which is unusual. So overall, HF propagation was humming, at least until the Kp index hit 5. Maximum useable frequencies, or MUFs, over a 3,000km path during daylight continue to be around 21MHz, but often dip to 18MHz at times. Nighttime conditions can be variable. If the 14MHz band isn't open for you, try 10MHz. Earlier in the week, some daytime tests with WSPR on the 20m band saw stations logged from Australia and the far west of Canada. DP0POL, the Polarstern research vessel doing work in the Artic, was also logged. Next week, NOAA predicts that the solar flux index may decline slightly to be in the range of 130 to 135. Geomagnetic conditions are predicted to be settled until the 1st of August, when the Kp index could rise to 4. This period of unsettled conditions, with reduced MUFs, could last until the 4th of August. And now the VHF and up propagation news from G3YLA and G4BAO We will see the return of a weak ridge of high pressure today. This will last until the middle of the coming week. The second half of the week will be a little more unsettled with some occasional spells of rain. This suggests that some Tropo is possible, before a gradual swap over to rain scatter. However, high pressure near the Azores may still influence the western side of Britain. This week will see the peak of two meteor showers, the Alpha Capricornids and Delta Aquariids. These are worth checking out, if only to get your practice time in before one of the major showers of the year – the Perseids on the 12th and 13th of August. Barely a day passes without some auroral alert, and this can be an exciting mode. Several good indicators are available, such as when the Kp index is above 5, or watery-sounding signals on the 40 and 20m bands. If you hear these, try looking north on the 6, 4 or 2m bands. Sporadic-E continues to be mentioned on the clusters somewhere in Europe on most days. But remember that it's a very localised mode and is rarely available for everyone at the same time. The best way to track it down is to use the clusters and a good list of beacons, to see who your ‘locals' are working on FT8. It's a very hit-and-miss mode. Meteor activity is a good indicator, whereas a high Kp index is a bad one. Whether it happens is often a balance between many opposing components. So, even a potentially good day may not be good where you are. The good news is that the last openings of the summer can occur into the first week of September. Moon declination is still positive but going negative again on Tuesday, the 29th. Moon windows and peak elevation will reduce. Path losses are rising now as we are past perigee. 144MHz sky noise starts the coming week low but will rise to moderate by the weekend. And that's all from the propagation team this week.

Ron Demcko, WA2TBQ, found his way into electronics—and later amateur radio—thanks to the early influence of his older brother, John, KD7JR. From a young age, Ron funded his growing passion for kit building and radio experimentation by buying and reselling surplus electronic gear, a resourceful start that helped pave the way for his formal education. Today, Ron is a recognized expert in the field of radiation-resistant passive components, essential for military and space applications. On the air, CW remains his favorite mode. We cover all of this and much more in this episode of QSO Today.

GB2RS News Sunday the 20th of July 2025 The news headlines: The RSGB launches GB70RS awards to celebrate 70 years of GB2RS New volunteer RSGB STEM Champion announced Visit the RSGB National Radio Centre during the summer holidays The RSGB's weekly news broadcast, GB2RS, is celebrating its 70th anniversary this year. To mark the occasion, the Society is inviting you to collect awards for listening and logging GB2RS News broadcasts between Friday, the 1st of August and Tuesday, the 30th of September. There are four categories, including a basic listener award and a regular listener award. Full details of the programme, the rules and how to apply for your certificate are available by searching GB70RS at QRZ.com. To read about the awards and wider celebrations that are taking place for the 70th anniversary of GB2RS, go to rsgb.org/gb70rs RSGB Board Director, Ben Lloyd, GW4BML, has appointed Ian Stevenson, G3YNU, as the volunteer RSGB STEM Champion. This new role fits with the RSGB's strategy to bring amateur radio to new audiences and to highlight the link between amateur radio and science, technology, engineering and maths. Ian brings a wealth of experience to this role, having been a mathematics teacher for ten years, with a further 23 years in Higher Education as a Senior Lecturer in ICT and Education. Ian also played a pivotal role in establishing the RSGB School Links Project, which introduced classroom activities that connect amateur radio with the school curricula. The project was established following Tim Peake's Principia mission to the International Space Station, which included ten UK ARISS school contacts during Tim's time in space. In his new RSGB role, Ian is enthusiastic about fostering close ties with STEM organisations and STEM ambassadors across the UK, including those already engaged with the RSGB. If you'd like to contact Ian to share suggestions that may enhance the RSGB's STEM outreach programme, you can contact him via stem.champion@rsgb.org.uk If you are looking for an activity to keep the children busy during the summer holidays, why not plan a visit to the RSGB National Radio Centre at Bletchley Park? The knowledgeable and welcoming volunteers will be on hand to give an introduction to radio technology, how it works and why it is still relevant today. There are interactive displays as well as the opportunity to get a certificate for sending your name in Morse code. There will also be three more of the successful Spy Transmitter events during the summer, so keep an eye on the Bletchley Park website and the RSGB comms channels if you'd like to take part. Start planning your visit by going to rsgb.org/nrc. Don't forget that as a membership benefit, RSGB members can visit the world-famous Bletchley Park estate, including the RSGB National Radio Centre, for free.

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

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 17th of July. Space weather has been a bit like our terrestrial weather this week. We have had sunspots, some C-class solar flares, some coronal mass ejections and a large coronal hole – unsettled, you could say! Luckily, the coronal mass ejections were not Earth-directed, but the Kp index did rise to 5 on the 15th of July and again late on the 16th of July. The large coronal hole, which may have been responsible, is well south on the Sun's surface and should rotate out of Earth's view by the beginning of the coming week. Meanwhile, the Sun appears to have woken up, spot-wise, with 11 groups on the 17th of July, four of which are classed as growing, while two are stable and three are declining. Two groups are unclassified at this time. This resulted in an increase in the solar flux index to 152 on Thursday, the 17th. Overall, this means quite reasonable HF conditions considering the time of year. Recent DX spots included the JW0V DXpedition to Svalbard on both SSB and FT8, and C93RRC in Mozambique on 17m CW, plus 30, 20 and 10m FT8. Conditions have been up and down, with daytime maximum usable frequencies, or MUFs, over a 3,000km path reaching 28MHz at times, but then quickly declining to 18 or 19MHz ten minutes later. All we can advise is to keep listening! Nighttime MUFs over a 3,000km path have generally been exceeding 10MHz, and occasionally reaching 14MHz. We may start to see nighttime 14MHz openings tailing off as we head into late July. Next week, NOAA is a little pessimistic with a predicted solar flux index in the range of 118 to 130. Unsettled geomagnetic conditions, with a possible Kp of 4, are forecast for Tuesday, 22nd of July. And now the VHF and up propagation news from G3YLA and G4BAO The unsettled weather over this weekend will continue through the first part of the coming week. Some of the rain will be heavy and possibly thundery, so there is a good chance of rain scatter on the GHz bands. After mid-week, the pattern may change enough for a weak ridge of high pressure to build close to the UK and this may offer some Tropo opportunities. It may not be strong enough for it to persist through the warmth of a July day. Thus, most places will have better Tropo prospects overnight. The solar conditions have recently fired off a steady stream of aurora alerts, and we should probably expect similar in the coming week. Meteor scatter is often on people's minds during late summer since we have two showers towards the end of this month and, of course, next month's Perseids. This month, both the Delta Aquariids and the Alpha Capricornids peak around the 30th of July, but we are already in the broad spread of dates for activity. Sporadic-E is still happening on most days somewhere within Europe, but even UK stations can expect regular FT8 activity and a fair chance of CW or SSB paths for stronger events. Last Wednesday saw another early afternoon opening into the USA. These stronger events need a low Kp index, below 3, and some jet stream activity to generate turbulence that can spread upwards to the E region. In the coming week, we will certainly have some jet stream activity, so it should be worth monitoring your favourite beacons for activity. It's always helpful to have a list of favourite beacons at the ready to cover a range of directions. For example, one in Finland, Poland, Hungary, Italy and Spain should cover it. Moon declination is positive again, reaching maximum on Tuesday, the 22nd, with associated long Moon windows and high peak elevation. Path losses continue to fall until perigee today, Sunday, the 20th. 144MHz sky noise is moderate, but Thursday the 24th sees the Moon and Sun close in the sky until early the following day. And that's all from the propagation team this week.

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

On Sunday the 20th, the RSGB International Low Power Contest runs from 0900 to 1600 UTC. Using CW on the 80, 40 and 20m bands, the exchange is signal report, serial number and transmitter power. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 10th of July 2025 Last week was characterised by settled geomagnetic conditions, but a relatively low solar flux index. The Kp index hit 5.33 on the 6th and 7th of July but was otherwise around 1 or 2 for the rest of the week. These settled conditions were helpful to HF propagation, although the maximum usable frequency over a 3,000km path didn't get much above 21MHz. This is likely to be due to the HF summer doldrums, and we are unlikely to see it rise much more until September, once the F2 layer has switched to autumnal propagation conditions. Meanwhile, the solar flux index remained steadfastly in the range of 115 to 120. This is enough to provide fair propagation, but not enough to set new DX records! But there was DX to be worked, including T30TT in western Kiribati, on the 20 and 15m bands using the FT8 Fox and Hounds mode. Also, ZD7FT was operating on St Helena Island on the 17m band using SSB, and C94RRC was active on the 10m band from Mozambique using FT8. Laurie, G3UML on the CDXC Slack group, commented that there was a lot of DX around, including FP/KV1J on the 17m band using SSB on Miquelon Island. Additionally, TY5AD was on the 17m band using CW from Benin. And FY4JI was on the 17m band using SSB from French Guiana. Now the bad news. A very large solar coronal hole will begin to face Earth this weekend. A solar wind stream flowing from this zone is expected to reach Earth with the main influence occurring today, the 13th, and tomorrow, the 14th. If the Bz of the plasma cloud points south, we can expect disturbed geomagnetic conditions and a reduction in the maximum usable frequency, or MUF for short. NOAA predicts unsettled conditions, with a Kp index of 4 between the 15th and 16th of July. The solar flux index is expected to be in the range of 105 to 125 for the next week. And now the VHF and up propagation news from G3YLA and G4BAO The hot weather continues to set the agenda in the short term. Something to note is that for VHF and UHF Tropo ducting, the ideal is for warm, dry air to sit on top of cool, moist air. These conditions are commonplace over the nearby seas as hot, dry air moves out across the coast to overlay the cool, moist air near the sea's surface. Think of the North Sea, English Channel, Irish Sea and Biscay as being very good Tropo paths in high summer. But the award goes to the Mediterranean, where very strong ducting conditions are pretty much a given if you happen to be sitting on an exotic holiday beach.  Back at home... if you live inland, then you will be out of luck during the heat of the day since there is no cool, moist surface air. But in the evening, as the ground cools and perhaps cool sea air moves inland, you could find yourself coupled into the Tropo conditions that those on the coast have been enjoying all day. In other words, for most of the country, Tropo will be better overnight and early morning. The other modes are worth checking of course, especially Sporadic-E, which is continuing to give some paths on most days, at least for digital modes, but also for those using SSB or CW.  Most days, there will be some direction available from the UK on the 10m band, and perhaps on the 6m band, with many online clusters to show you where the current paths are located. We really must get used to the idea that Sporadic-E can be very localised, and you will only know about it if someone calls CQ. If you do that, you may be surprised by how good conditions have been all along! Disturbed solar conditions should keep aurora as a possibility. Meteor scatter is often worth checking, with two showers peaking later in the month. The middle part of the coming week looks like turning more unsettled for a time, so rain scatter is also an option for the GHz bands. Moon declination is increasing again, reaching maximum on Tuesday, and path losses are falling. So, it's time to put the feeder back into the dish. 144MHz sky noise is moderate to start the week but decreasing to low after the weekend. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of July 2025 It looks like the Space Weather Prediction Centre, which supplies the forecasts for NOAA, were overly cautious last week. Despite predicting geomagnetic disturbances, we had quite a calm week. The Kp index rose to 3.33 on a few occasions, but that was it. We ended up with settled geomagnetic conditions and a solar flux index in the 120s to 130s. A warning about the impact of a coronal mass ejection, or CME, which left the Sun on the 28th of June, appeared to come to nothing. This made a much-needed change to the unsettled conditions of previous weeks. As a result, maximum usable frequencies, or MUFs for short, over a 3,000km path have been above 21MHz at times. At night, MUFs over the same path have been consistently above 14MHz, which is normal for this time of year. In the summer, we can expect to see nighttime MUFs being consistently higher than in the winter, due to a change in ionospheric chemistry. Unfortunately, this also means that daytime MUFs are lower than in winter, leaving 28MHz open to Sporadic-E instead. According to DXMaps.com, it appears that most Sporadic-E openings on the 10m band have favoured the southeast of the UK towards Italy, Turkey and Greece. Back to F2-layer propagation now. On the 20m band, E51JD, operating from the South Cook Islands, was spotted on SSB by Laurie, G3UML, on Thursday morning. KH7AL/KH9 on Wake Island, and T30TTT on Kiribati, have also been worked on the 20m band using FT8. Next week, NOAA predicts that the solar flux index will be in the 125 to 145 range. Geomagnetic conditions are predicted to be quiet, apart from the period around the 11th and 12th of July, when the Kp index may rise to 4. And now the VHF and up propagation news from G3YLA and G4BAO This hot weather has provided some nice marine Tropo around the coasts recently as hot, dry air advects across the cooler, moist surface layer. We have also been able to see the duct move inland in the evenings. The hybrid weather pattern of low pressure to the north of Britain and high pressure to the south will continue to produce some Tropo paths, particularly across the Channel, Biscay and North Sea.  Northern areas of Britain will see occasional fronts and active weather systems, together with breezier weather, making Tropo unlikely here. The higher pressure to the south means that rain scatter may not feature much unless isolated thunderstorms develop when weak weather fronts eventually reach these southern areas. In the north, it's a different matter, and there could be some heavier rain that might produce some rain scatter on the GHz bands. Meteor scatter did well during June with several important showers to boost chances. July offers two showers. The first is the low-hourly-rate Alpha Capricornids, and the second is the Delta Aquariids. Both of these peak around the 30th of July, so we have a while to wait. There have been some minor auroral events recently, and it's always possible that solar activity could lift the Kp index high enough, but we are not expecting great things. Keep a check on the Kp index at spaceweather.com  to see if anything is happening. The Sporadic-E season has had occasional good days, but for much of the time, the focus of activity has been too far into Europe for the whole country to take advantage of it. To begin the coming week, the position of the jet streams suggests paths to northern Europe and the Baltic will offer best results. Later in the week, the emphasis shifts to the Balkans and Italy, and then to Iberia. The Moon reaches apogee tomorrow, the 7th, where path losses are at their highest. Moon declination is negative all week, with the lowest, or the most negative, on Wednesday, the 9th. 144MHz sky noise is moderate but increasing to a high of around 2,300 Kelvin on Wednesday. And that's all from the propagation team this week.

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

Foundations of Amateur Radio The other day Randall, VK6WR, encouraged me to get on-air. He described it like this: "There is a mystery signal on 40m that you can try your new Universal Radio Hacker skills on. It appears to be a FSK signal separated by 7kHz with the two signals at 7.0615 and 7.0685 MHz. Each of them on their own sounds a bit like a Morse signal, but my CW decoder decodes junk. But if you can see it on a spectrum scope, it is clearly FSK because either one of them is on at any time." He went on to say: "You'll need an SDR to receive the signal given the separation, but could be a fun investigation!" Having just discovered "Universal Radio Hacker", a tool that can help you decode radio signals, that sounded like something I'd love to have a go at. Unfortunately, after the demise of my main workstation last year, my current set-up doesn't allow me to do such recordings, but Randall, ever the gentleman, provided a recording of the signal. He writes: "This was captured with gqrx demodulating the signal as SSB audio with the VFO tuned to 7.060, so both "signals" are there, one very low freq and one very high freq." If you're curious, I've uploaded the file as it was shared with me to my VK6FLAB GitHub repository under "signals". Over the next two days I spent my time attempting to decode this signal. I opened up Universal Radio Hacker and spent delightful hours getting precisely .. nowhere. Some of that is absolutely my unfamiliarity with the tool, but this is a great exercise in learning on the fly, where truth be told, I tend to live most of my life. It wasn't until several hours later that I decided I should at least listen to the audio. To my ear it sounded like 25 WPM Morse Code, but being still in the learning phases, while my brain was triggering on the sequences, decoding wasn't happening. Of course I could cheat and forward the audio to one of my fellow amateurs, but the actual message wasn't really the point of the exercise, at least not at this stage. Instead I fired up "multimon-ng" which has an in-built Morse decoder. I spent some hours doing more Yak Shaving than I was expecting, but even then, I still didn't get more than gobbledegook out of the process. I used "Audacity" to shift one of the signals by one wavelength and mixed them together. This allowed me to reduce the noise significantly, but still none of my tools did anything useful. In case you're wondering why, if you have a tone and noise and shift one signal by the wavelength of the tone, then mix them, the tone adds to itself, but the noise, random in nature, is just as likely to add as it is to subtract, so in effect, you're increased the signal to noise ratio. After multimon-ng failed, I tried an online Morse decoder, which gave me all manner of text, but none of it made sense to me. Of course it's possible that this is someone rag chewing in a different language, but I couldn't make any sense of the thing. I did come up with some issues that prompted me to create the signal repository. I realised that I didn't have any known "good" signals. Previously I'd tried decoding a sample FT4 signal, but that went nowhere, mainly because the signal was noisy. So, what I'm going to do over the next couple of weeks is create some clean, as-in, computer generated, known signals, and add them to the repository. The aim is to have a known good starting point to learn from. In software development this technique is often used to limit the number of unconstrained variables. In our case, if I generate a known good Morse Code signal, then I can learn how to use Universal Radio Hacker to decode it, so when I come across an unknown signal, I can use the techniques I learnt to attempt to decode it. Feel free to make pull requests with known good signals yourself. RTTY, PSK31, WSPR, FT8, etc. Feel free to include non-amateur modes. One thing, I'm not looking for off-air recordings of signals, yet, that can come later, right now I need signals that are pure, as-in, as I said, computer generated. Of course at some point, perhaps sooner rather than later, I'll discover that generated signals are no easier to decode than off-air recordings, but that's for another day. Meanwhile, you too can play. Download one or more sample files and decode them. Let me know what you learn. I'm Onno VK6FLAB

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

Last week, we mentioned a large coronal hole on the Sun that might cause problems. The hole is so large that it is still Earth-centric seven days later. We had expected the hole to increase the Kp index due to the solar wind emanating from it. However, as of Thursday, the 19th of June, conditions remained quiet with a Kp index of 2. As geomagnetic conditions have remained calm this past week, it has been quite good for HF. 15m has been one of the better bands, with openings to both the east and west, depending on the time. As is the way nowadays, most of the activity has been on FT8, but it has opened up opportunities to work the Far and Middle East, as well as South America. The solar flux index has generally been in the range of 130 to 150, with a peak of 161 on the 15th of June. The Sun has been active, with a near X-class solar flare being observed around sunspot region 4114. This peaked at 1805 UTC on the 15th of June. There was also an X-class solar flare at 21:49 UTC on the 17th of June. This latter event was late in the evening, so it had little impact on the UK, other than to potential paths to the west. Maximum usable frequencies, or MUFs for short, declined a little during the past week, with openings on 21MHz becoming a little scarcer. It is useful to operate as close to the MUF as possible to minimise the effects of D-layer absorption and maximise the chances of working DX. Next week, NOAA predicts the solar flux index will be in the range of 125 to 145. Unsettled geomagnetic conditions are forecast for the period from the 24th to the 27th of June, with a maximum predicted Kp index of 5. If the Kp index is low, then we have a good chance of 21 MHz openings to South America in the evening. As we pass the summer solstice, we may even expect 14 MHz to remain open to DX throughout the night. We can also expect Sporadic-E to continue to provide short-skip openings on 28 MHz, and even the lower HF bands, such as 14, 18, 21, and 24 MHz. And now the VHF and up propagation news from G3YLA and G4BAO After a week of high pressure, this weekend returns to something more normal with showery rain and a series of weather fronts and showery interludes in the coming week. This will mean that rain scatter on the GHz bands is worth considering. Also, since we are into the summer season, the chances of some rain being heavy and thundery is a good signal for rain scatter. This sequence of low-pressure weather suggests that high pressure and Tropo will be less likely to make a big impact on the coming week's operating log. Any sign of high pressure will tend to be towards the south of the UK and over the continent. In very hot weather, the conditions can be good for low-level surface ducts across cooler seas. So, if you are tempted, then go for coastal or maritime paths up the east coast or across Biscay, for example. Meteor scatter may benefit from the late June Bootids, which peak on Friday, the 27th of June and the daytime Beta Taurids, which peak on the 28th of June. These are small showers, but they can also be important for contributions to long-lived metallic ions, which are the building blocks of Sporadic-E propagation. Aurora continues to appear with occasional radio events, but there is too much daylight for anything visual. As an alternative, you might see glimpses of noctilucent clouds low down on the northern horizon. These form in the mesosphere, at about 80km, as ice crystals form on meteor dust and can exhibit complex wave patterns. These are both good omens for Sporadic-E. The summer Sporadic-E season is well underway now. It is advisable to check the usual cluster maps and the propquest.co.uk  website for daily updates. It's also worth making use of the longer daylight and weather patterns over the polar regions for paths to the Far East. The Moon reaches perigee, its closest point to Earth, tomorrow, the 23rd, so path losses are low. Moon declination also reaches a maximum positive value on the 25th of June. This will mean that there are long Moon windows. 144MHz sky noise is moderate, increasing to high by tomorrow, the 23rd. The New Moon is on the 25th of June, so expect high noise levels due to its proximity to the Sun. And that's all from the propagation team this week.

GB2RS News Sunday, the 15th of June 2025 The news headlines: Book now to secure your place at the RSGB 2025 Convention The RSGB launches the “SES Cookbook” The RSGB Operating Advisory Service issues advice The RSGB annual Convention is a fantastic opportunity for radio amateurs to meet, learn and share experiences. Whether you're newly licensed or have years of experience, there is always more to discover. That's why the Society is excited to introduce this year's theme: “Discover, Learn, Progress”. Whether you want to discover something new, learn more about a particular aspect of amateur radio, or progress and develop your skills, you'll find something at the Convention to explore and enjoy. The prestigious event will take place between October 10th and 12th at Kents Hill Conference Centre in Milton Keynes. Book now to secure your place in joining like-minded people for what is also one of the best social events in amateur radio. Take advantage of the early-bird prices by going to rsgb.org/convention. The Society is delighted that the event will be sponsored again by Martin Lynch and Sons. Special event stations are popular around the world and a great source of fun and excitement for organisers and QSO chasers. They can also be a fantastic tool for outreach, allowing you to demonstrate amateur radio and encourage people to find out more. But how do you organise an event to achieve all those objectives? The RSGB has just launched a new web section that focuses on special event stations. For RSGB members and Affiliated Clubs, there is an online guide called the SES Cookbook, which offers a wide range of practical guidance to help you deliver the best experience for your visitors and the organisers. The guide covers a wide range of topics, including how to apply for a special event station callsign, the stages of the planning process, publicising your event to attract visitors and how to make a good number of contacts. For non-RSGB members, there is a simple guidance document that outlines the main things to consider when planning this type of event. The new section also draws together existing information about permanent special event stations as well as QSL guidance. If you're planning an event for this year, or even for next year, now is the time to make the most of this comprehensive guide. Go to rsgb.org/ses  to find out more. The RSGB Operating Advisory Service, or OAS, provides advice to members on dealing with situations that are not within the spirit of amateur radio. From time to time, this activity goes beyond what is classed as acceptable behaviour and requires action to be taken. In these circumstances, the OAS recommends reporting the matter directly to Ofcom and to the police in the case of issues which could be classed as harassment, stalking or hate crimes. Experience has shown that this carries more weight coming directly from the people hearing or suffering the problem rather than a third party, such as the RSGB. If you hear anything that is not acceptable behaviour, contact the RSGB OAS first, and the team will suggest the correct course of action. Once Ofcom and the police have issued reference numbers, these should be passed to the Operating Advisory Service. You can contact OAS via oas@rsgb.org.uk The RSGB has submitted responses to a pair of Ofcom consultations. The first considered a series of licence exemption updates, including arrangements for some visiting radio amateurs to the UK. The second concerned filing procedures for the growing number and variety of satellites. Both replies were developed by the RSGB Spectrum Forum, drawing on its members' wide breadth of expertise. The Spectrum Forum expects that there will be further updates to both topics. Find the full replies by going to rsgb.org/spectrumforum  and selecting the ‘Papers and Consultations' option from the right-hand menu. The RSGB recently announced two new volunteering opportunities. The RSGB CW Champion will help the Society in taking Morse code to new audiences. Tasks will vary from developing the CW content on the RSGB's website through to developing and supporting a team of enthusiastic individuals who can support CW-related activities. The second role requires an individual with experience in science, technology, engineering and mathematics. The RSGB STEM Champion will help the Society to reach new audiences, build relationships with related organisations and encourage more young people into STEM careers. Go to rsgb.org/volunteers  to read the full role descriptions and learn how to apply.

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

On my birthday this year, I traveled to a nearby Park and activated the Park on 12-meter FT8. I love working the 12-meter band when it is open, which is not often.Equipment used in this video:ICOM IC-705 - https://amzn.to/3Zbg5avTarheel Little Pro HP - https://tarheeldesigns.com/portable-antennasM&P Coax - https://hr2.li/cablesBecome a supporter of this podcast: https://www.spreaker.com/podcast/ham-radio-2-0--2042782/support.

GB2RS News Sunday, the 25th of May 2025 The news headlines: Apply to become the RSGB's new CW Champion The Tonight@8 series continues in June with Morse code Could you be the RSGB's new STEM Champion? As part of the RSGB's ongoing strategy to take amateur radio to new and diverse audiences, it is seeking to appoint a volunteer CW Champion. Whilst the need for a CW test has been removed from the licensing requirements, there is still a strong interest in the mode. Recent communications and activity involving Morse have received high levels of interest, and the Society would like to do all it can to encourage and promote CW within the hobby. This new role will take the lead with activities including managing RSGB web content relating to Morse code and contributing to the GB2CW broadcasts. The volunteer will also be tasked with building a team of enthusiastic individuals who can support CW-related activities undertaken by the Society. This role is intended to help take Morse to new audiences with an emphasis on learning and development to further the skills of RSGB members. Read the full role description, as well as details of how to apply, by going to rsgb.org/volunteers The next webinar in the Tonight@8 series is on Monday, the 2nd of June.

Using CW on the 80m band, the exchange is signal report and serial number.    Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 22nd of May 2025 A high-speed solar wind, originating from a massive coronal hole, took its toll on HF this past week. During the weekend of the 17th and 18th, the Kp index was above four for nine of the three-hourly recording periods. Unfortunately, the feed from the Dourbes Digisonde failed over this period, so we can't comment on what effect this had on maximum usable frequencies, or MUFs for short. Later in the week, geomagnetic conditions improved, despite the coronal hole still being Earth-centric, and the Kp index fell to more reasonable levels, sometimes in the ones and twos. An M3.2 solar flare was observed at 08:21 UTC on the 19th of May. The source was located off the northeast limb, so perhaps we can expect more as it turns to become more Earth-facing. Unfortunately, the solar flux index also fell to lower levels, reaching 119 by Thursday, the 22nd. In fact, on that day, it had been below 120 for more than seven days. But all is not lost, as a solar flux of more than 100 is usually enough to keep the HF bands open. MUFs over a 3,000km path have generally reached 21 MHz and have often peaked at 24 MHz at times. It is quite normal for the F2-layer MUF not to reach 28MHz due to a change in the ionospheric chemical make-up in the summer – the so-called summer doldrums. However, Sporadic-E may keep 10m alive, so don't write the band off. Propagation, at the moment, favours paths into the southern hemisphere, although each band can have different characteristics at different times. A quick play with the propagation tool at tinyurl.com/propcharts  will show you what we mean. Next week, NOAA predicts that the solar flux index will remain around 120 until the 27th of May, after which it could rise to 140 by the end of the month. Unsettled geomagnetic conditions are forecast for the period from the 28th of May to the 2nd of June. This could see the Kp index peak at five or six with corresponding drops in the MUF and DX. As we are now on the downward portion of this solar cycle, we may expect more geomagnetic disturbances from coronal holes and coronal mass ejections. And now the VHF and up propagation news from G3YLA and G4BAO The long run of fine settled weather seems to have drawn to a close. We have a period of changeable and, at times, wet and windy weather to deal with over the coming week. I doubt we will see much, if any, Tropo except perhaps towards the end of the week as some models show a new high building as we move into June.  Before then, the various fronts and showers will bring several spells of rain and a much greater chance of rain scatter on the GHz bands than recently. The solar conditions have again provided weak auroral events, with fluttery signals on the HF bands being a good indicator, since the bright evenings and early dawns leave little chance of any visual clues. As usual, the measure to follow is the Kp index. So, look out for values of Kp going above five to generate interest. Meteor scatter is declining as the last of the Eta Aquariids play out, following a long tail from the peak on the 6th of May. Meteors also make up the content of Sporadic-E because, as they burn up, they produce long-lived metallic ions that can be focused into thin layers of Sporadic-E. There are some less well-known meteor showers in June. So, next week there may be more to say. In the meantime, random meteors and declining Aquariids will have to suffice. Now, on to Sporadic-E. This is beginning to be the primary mode in these summer weeks. It is sensible to check during main operating windows in the morning, late afternoon and early evening. Ideally, we require meteor input, a low Kp index, plus some weather triggers to set up atmospheric gravity waves which produce the right wind shear in the E region. Jet streams are usually the best clues for where Sporadic-E might form.  Use the daily Sporadic-E blog on the Propquest website to get an insight of the current day's weather patterns – see propquest.co.uk   If you have very limited time and have still not worked Sporadic-E, just checking 50MHz in the late afternoon will ensure that you make a start this year. EME path losses are still falling as the Moon reaches perigee, its closest point to Earth, on the 26th of May. Moon windows and peak elevation are again rising, reaching a maximum on the 29th of May. 144MHz sky noise is low and remains low as the week progresses. And that's all from the propagation team this week.

Hello and welcome to episode 69 of The DX Mentor – A discussion with Jim, WB2REM. Thank you for joining us. I'm Bill, AJ8B.If this is the first time you are joining us, Welcome! We have a back catalog covering many aspects of DX. Please check us out. If you like what you find, please subscribe to always be notified of a new podcast!    Another way to keep in touch and to see what we are up to is via the DX Mentor Facebook page. I will be posting aboutupcoming podcasts as well as other DX events so please follow us.  Our guest today is Jim, WB2REM. Jim is an experienced, passionate operator and the conversation should be lively and informative.Here is the Mission Statement for this DXPedition: "In the spirit of the 7163/7156 MHZ DXGroup, this DXpedition was formed to provide the Amateur Radio Community with the opportunity of working the Faroe Islands on 6-160 Meters. We plan to be active on SSB, CW and FT8. We also hope to get to know the Amateur community in the Faroe Islands and when possible, explore the natural wonders of the islands, when not operating.

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

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

Foundations of Amateur Radio Over the years I've talked about different ways of using our license to transmit. I've discussed things like modes such as voice AM, FM, and SSB, and digital modes like FT8, WSPR, RTTY, FreeDV, Hellschreiber, Olivia and even Morse code. Recently it occurred to me that there is something odd about how we do this as a community. Now that I've realised this it's hard to unsee. Let me see if I can get you to the same place of wonder. Why is it that we as amateurs only use one such mode at a time? Let me say that again. With all the modes we have available to us, why do we only use one mode at a time, why do we get our brain into the mindset of one activity, stop doing that in order to move to another mode? It's weird. Amateur radio is what's called "frequency agile". What I mean by that is we are not restricted to a fixed number of channels like most, if not all other radio users. We can set our transmission frequency to whatever we want, within the restrictions imposed by our license conditions, and start making noise. There's agreement on what mode you can use where, but within that comes a great deal of flexibility. We have the ability to find each other. Call CQ and if the band is open and your station is transmitting a signal, the chance is good that someone somewhere on planet Earth will respond. We change frequency at will, almost without thought, but why don't we do this with modes? The closest I've seen is local VHF and UHF contests where you get different points depending on which mode you're using, and even that seems hard fought. It's weird. We have an increasing range of Software Defined Radios, or SDR, where your voice, or incoming text, can be transformed to a different mode at the touch of a button, but we rarely if ever actually use this ability. In case you're thinking that the restriction relates to the availability of SDR in the average amateur radio shack, most amateur modes fit within a normal audio stream and that same flexibility could be applied to the vast majority of transmitters scattered around the globe, but to my knowledge, it isn't. Why is that? Better still, what can we do about it? Can we develop procedures and processes to make us more, let's call it "mode agile", giving us the ability to change mode at the same ease as we change frequency? What would a "mode and frequency agile" amateur look like? What processes would you use? Right now the best we have is to QSY, or announce that we're changing frequency, but I've never heard anyone use that to describe a change of mode. Of course it's possible that I've led a sheltered life and not been on-air enough, but if that's the case, I'd love to hear about it. So, what is stopping us from becoming even more flexible? Do we need to practice this, develop better tools, teach new amateurs, have multimode nets, invent new modes that share information across different modes simultaneously, build radios that can transmit on different frequencies, or something else? I'm Onno VK6FLAB

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

  GB2RS News Sunday, the 6th of April 2025   The news headlines: Last chance to submit your question ahead of Saturday's RSGB AGM Tom Wardill, 2E0JJI has been appointed as RSGB Maker Champion Reduced exam slots over Easter weekend The RSGB 2025 AGM is taking place at 10 am next Saturday, the 12th of April. The Society is encouraging RSGB members to take the time to vote for the two resolutions that need your approval. During the AGM, Board members will be answering your questions. Whether your question is about the RSGB, the Board, any of the RSGB services or even the future of amateur radio, your contribution to the discussion is important. Priority is given to questions submitted live by Zoom or by the Society's web form, so get in touch now rather than waiting for the live chat option on the day. The Zoom question deadline is 9 am on Monday, the 7th of April, and the deadline for submitting a written question is when voting ends at 0900 on Thursday, the 10th of April. Following the formal business of the AGM, the RSGB is delighted that RSGB President John McCullagh, GI4BWM will be sharing his review of 2024.

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

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

GB2RS News Sunday the 23rd of March 2025 The news headlines: The RSGB launches its new web app RSGB Elected Board Director unopposed candidates are announced Full details of the RSGB 2025 AGM have been released The RSGB is excited to give you a first look at its new app! The web version has just been launched and is a one-stop shop for all RadCom publications and club newsletters. You can find the web version at rsgb.org/radcom It gives RSGB members easy access to over ten years of back issues of RadCom, as well as RadCom Basics and Plus. The Society will be adding more back issues of RadCom from the archive in the coming months, making it even more valuable. All you need is your RSGB membership portal details to access the editions. If you're not an RSGB member, you can still view a sample edition of RadCom through the web version of the app. If you like what you see, you can become an RSGB member via rsgb.org/join which will give you access to the back issues of RadCom and its sister publications. Watch this space for news of the release of the RSGB mobile app later this year. For some roles in the RSGB elections, a single nomination was received. These include the two vacancies for Elected Board Directors. Peter Bowyer, G4MJS and Mark Savage, M0XIC will each take up the role of Board Director at the end of the RSGB AGM on the 12th of April 2025. Both were interviewed separately to enable RSGB members to hear their views on the current issues facing amateur radio and the Society. Their answers were combined into two videos: the first ‘short' video is just two quick questions, and the second video is a more in-depth interview. You can watch them both on the RSGB website and its YouTube channel. For more information about each of these unopposed candidates, see the April 2025 issue of RadCom or go to rsgb.org/candidates The RSGB 2025 AGM will take place at 10 am on Saturday the 12th of April. The event will be held online to ensure that as many members as possible can watch and take part. The formal business of the meeting will include the results of members' votes on the resolutions and details about the election.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The 10 operators made almost 90,000 QSOs on 160 – 6 meters on CW, SSB, RTTY, and FT8. Our guests today are Adrian, KO8SCA, Johannes, PA5X, and Joe, W8GEX. This past weekend, the W8S DXpedition was recognized as the 2023 SWODXA DXpedition of the Year! At that time of this recording, we did not know that this group would be the DXpedition of the Year. "From October 4, 2023 until October 17, 2023 an international team of 10 operators will be active from Swains Island as W8S. QRV on all HF bands in CW, SSB, FT8 and RTTY with 6 stations from 2 separated camps." Introductions W8GEX – Joe went to Swains in 2012. He is the co-host. I think this will be a great conversation.

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

Tune in for a journey through the intriguing and impactful world of ham radio with Linus Balsys, L2YH. in this QSO Today.

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

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