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

Foundations of Amateur Radio Since becoming a licensed amateur in 2010, I have spent a good amount of time putting together my thoughts on a weekly basis about the hobby and the community surrounding amateur radio. As you might know, my interest is eclectic, some might say random, but by enlarge, I go where the unicorns appear. Over a year ago I mentioned in passing a community called HamSCI. The label on the box is "Ham Radio Science Citizen Investigation", which gives you a sense of what this is all about. It was started by amateur radio scientists who study upper atmospheric and space physics. More formally, the HamSCI mission is the "Continuation and extension of the amateur's proven ability to contribute to the advancement of the radio art." If you visit the hamsci.org website, and you should, you'll discover dozens of universities and around 1,300 people, many of whom are licensed radio amateurs, who are asking questions and discovering answers that matter to more than just our amateur community. For the eighth time the HamSCI community held an annual "workshop", really, an opportunity to get together and share ideas, in person and across the internet, a conference by any other name. Under the banner theme of "HamSCI's Big Year", over two days, 56 people representing 27 different organisations across 61 sessions, tutorials, discussions, tours, posters and demonstrations, explored topics all over our hobby, from the Personal Space Weather Network, capable of making ground based measurements of the space environment, to the Whistler Catcher Pi, a project to record the VLF spectrum to 48 kHz using a Raspberry Pi. You'll find research into HF antennas for the DASI or Distributed Array of Small Instruments project and associated NSF grants, exploring measurements of HF and VLF, combined with GPS and magnetometer across 20 to 30 stations. There's discussions on how to explore Geospace Data, such as information coming from the Personal Space Weather Station network, or PSWS, using the OpenSpace project and dealing with the challenges of visualising across a wide scale, all the way up to the entire known universe. Did I mention that there's work underway to add PSWS compatible receivers to Antarctica? There reports on observations and modelling of the ionospheric effects of the April 2024 solar eclipse QSO party, including Doppler radio, HF time differences, and Medium Wave signal enhancements, not to mention planning and promoting future meteor scatter QSO parties. There's, post-sunset sporadic-F propagation, large scale travelling ionospheric disturbances, GPS disciplined beacons, the physical nature of sporadic-E propagation and plenty more. As you might have heard me say at one time or another, the difference between fiddling and science is writing it down. It means that you'll find every session has accompanying documentation, charts, graphics and scientific papers. Remember, there's eight years of reading to catch up with, or learn from, or play with. The publications and presentations section on the hamsci.org website currently has 526 different entries. You might not be interested in the impact of radio wave and GPS scintillation, or rapid fluctuation in strength, caused during the G5 geomagnetic storm that occurred on the 10th of May 2024, or a statistical study of ion temperature anistropy using AMISR, or Advanced Modular Incoherent Scatter Radar data .. or you might. In case you're curious, "anistropy" is the property of being directionally dependent, in other words, it matters in which direction you measure, which might have some relevance to you if you consider that we think of the ionosphere and radio paths being reciprocal. If it reminds you of isotropy, that's because they're opposites. The point being, that amateur radio is a great many things to different people. If you're a scientist, budding, graduate or tenured, there's a home for you within this amazing hobby. I'm Onno VK6FLAB

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 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.

Foundations of Amateur Radio Recently I saw a social media post featuring a screenshot of some random website with pretty charts and indicators describing "current HF propagation". Aside from lacking a date, it helpfully included notations like "Solar Storm Imminent" and "Band Closed". It made me wonder, not for the first time, what the reliability of this type of notification is. Does it actually indicate what you might expect when you get on air to make noise, is it globally relevant, is the data valid or real-time? You get the idea. How do you determine the relationship between this pretty display and reality? Immediately the WSPR or Weak Signal Propagation Reporter database came to mind. It's a massive collection of signal reports capturing time, band, station and other parameters, one of which is the Signal To Noise ratio or SNR. If the number of sun spots, or a geomagnetic index change affected propagation, can we see an effect on the SNR? Although there's close on a million records per day, I'll note in advance that my current approach of taking a daily average across all reports on a specific band, completely ignores the number of reports, the types and direction of antennas, the distance between stations, transmitter power, local noise or any number of other variables. Using the online "wspr.live" database, looking only at 2024, I linked the daily recorded WSPR SNR average per band to the Sun Spot Numbers and Geomagnetic Index and immediately ran into problems. For starters the daily Sun Spot Number or SSN, from the Royal Observatory in Belgium does not appear to be complete. I'm not yet sure why. For example, there's only 288 days of SSN data in 2024. Does this mean that the observers were on holiday on the other 78 days, or was the SSN zero? Curiously there's 60 days where there's more than one recording and as a bonus, on New Years Eve 2024, there's three recordings, all with the same time stamp, midnight, with 181, 194 and 194 sun spots, so I took the daily average. Also, I ignored the timezone, since that's not apparent. Similarly the Geomagnetic Index data from the Helmholtz Centre for Geosciences in Potsdam, Germany has several weird artefacts around 1970's data, but fortunately not within 2024 that I saw. The data is collected every three hours, so I averaged that, too. After excluding days where the SSN was missing, I ran into the next issue, my database query was too big, understandable, since there are many reports in this database, 2 billion, give or take, for 2024 alone. Normally I'd be running this type of query on my own hardware, but you might know that I lost my main research computer last year, well, I didn't lose it as such, I can see it from where I am right now, but it won't power up. Money aside, I've been working on it, but being unceremoniously moved from Intel to ARM is not something I'd recommend. I created a script that extracted the data, one day at a time, with 30 seconds between each query. Three hours later I had preliminary numbers. The result was 6,239 records across 116 bands, which of course should immediately spark interest, since we don't really have that many bands. I sorted the output by the number of reports per band and discovered that the maximum number of days per band was 276. This in turn should surprise you, since there's 365 days in a year, well technically a smidge more, but for now, 365 is fine, not to mention that 2024 was a leap-year. So, what happened to the other 90 days? We know that 78 are missing because the SSN wasn't in the database but the other 12 days? I'm going to ignore that too. I removed all the bands that had less than 276 reports per day, leaving 17 bands, including the well known 13 MHz band, the what, yeah, there's a few others like that. I removed the obvious weird band, but what's the 430 MHz band, when the 70cm band in WSPR is defined as 432 MHz? I manually created 15 charts plotting dates against SNR, SSN, Kp and ap indices. Remember, this is a daily average of each of these, just to get a handle on what I'm looking at. Immediately several things become apparent. There are plenty of bands where the relationship between the average SNR and the other influences appear to be negligible. We can see the average SNR move up and down across the year, following the seasons - which raises a specific question. If the SNR is averaged across the whole planet from all WSPR stations, why are we seeing seasonal variation, given that while it's Winter here in VK, it's Summer on the other side of the equator? If you compare the maximum average SNR of a band against the minimum average SNR of the same band, you can get a sense of how much the sun spots and geomagnetic index influences the planet as a whole on that band. The band with the least amount of variation is the 30m band. Said differently, with all the changes going on around propagation, the 30m band appears to be the most stable, followed by the 12m and 15m bands. The SNR across all of HF varies, on average, no more than 5 dB. The higher the band, the more variation there is. Of course it's also possible that there's less reports there, so we might be seeing the impact of individual station variables more keenly. It's too early for conclusions, but I can tell you that this gives us plenty of new questions to ask. I'm Onno VK6FLAB

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.

Darling Downs Radio Club news. Coming up on 10 May we're running our inaugural annual club Foxhunt and family day. The actual hunt will start at 1030 and will run no further than a 15 km radius from the starting location at Peacehaven Park in Highfields, just north of Toowoomba. The Fox frequency will be 145.650 kHz, and the hunt is going to be staged so that experienced hands and rank beginners can both have fun. Doesn't matter where you are in the state; we'd love you to come and join us - we already know of a few distant households who will come to stay in Toowoomba overnight, and the aim is to be as social as possible. The hunt will start from Peacehaven Botanic Park on Kuhls Road in Highfields and is also the location for the post-hunt BBQ. Tons of parking, easy access, wet-weather protection, and great family amenities. Our next club tech session is on Monday, 12 May, when Simon VK4TSC will join us from the Brisbane WICEN group to guide us on the WICEN state of mind, and talk about the Hip Pocket Challenge Horse enduro, which has been rescheduled for Southbrook on 28 June. Hello, I'm Geoff Emery, VK4ZPP, and I've been thinking. A comment about the quality of the image on one of the free-to-air TV channels started me thinking about progress. Compare the sound reproduction of a portable cassette player to a digital machine, and you can appreciate the way things have improved. With television, the images that we get when archived material is shown are appalling compared to the images we saw on the screens in our living rooms 30 or more years ago. Just as the digital TV was a vast improvement over the old PAL services, the newer HD is another jump ahead in home entertainment. This brought me around to thinking about the radios that I have used in the past. Budgets being what they are on the domestic front, most of my rigs have been 2 nd hand, so already showing their ages by the time I got to use them. From hybrid to fully solid-state HF radios, there seems not to be much difference in performance. For someone who started listening on the large console receiver dominating the lounge room and then went through home-made and commercial simple sets, it was amazing at the time what the multiband and multimode brand-name transceiver could do. Still, as most of us will have experienced, these older rigs had their own characteristics which made them good, but at times finicky and annoying on reception. They are perfectly usable, but you have to tolerate overlapping signals and front-end overload, from time to time, as they represent the technology of the period of manufacture. More recently, I was able to purchase an Asian SDR as my introduction to the multicoloured scrolling display. What a great little rig that has yet to do duty out in the rig. It is versatile and every bit a good as the best shortwave rig that I have owned. Over the past couple of weeks, I have been fortunate to use a full-blown 100W SDR transceiver made by a major Japanese company. Before receiving this piece of kit, I watched several online videos and took note of what users and reviewers had to say. I must say that I have yet to put a signal on air, and I have to fight the electrical noise which envelopes this QTH, but the received signals and sensitivity just blow me away. I am using a shortened centre-loaded vertical antenna in a poor location, but pulling voices out of nothing is amazing. There can be no trace on the display, and the audio is readable. There can be close-by signals without heterodyning, and I have yet to find out how this unit handles a really close-by and strong signal. I suspect it will use the AGC to the best advantage and still provide a clean signal through the speaker. I am impressed with the improvements that digital technology is providing now, and I hope we all appreciate the engineering developments for our recreation. I'm Geoff Emery, VK4ZPP, and that's what I think. How about you?

  GB2RS News Sunday, the 27th of April 2025   The news headlines: RSGB delegates attend special IARU Region 1 Interim Meeting in Paris Join the RSGB in celebrating World Morse Day Be part of the RSGB's team at the Youngsters on the Air summer camp The RSGB is participating in the International Amateur Radio Union Region 1 Interim Meeting in Paris this weekend. The event is of particular historical significance as it coincides with the centenary of the founding of the IARU in 1925, as well as the 75th anniversary of the establishment of IARU Region 1 in 1950. The French host society, REF, is also marking its 100th anniversary. This year's meeting in Paris reflects a broader scope than in previous years and, for the first time, includes ‘Youth Matters' on the agenda. It also covers the usual focus areas of HF, VHF, UHF and Microwave, as well as Electromagnetic Compatibility. The RSGB has been a key contributor to the meeting, submitting papers that include future options for the 23cm band and the harmonisation and protection of HF bands. Three delegates from the RSGB are attending the meeting in person, including the newly appointed RSGB President Bob Beebe, GU4YOX. There will be eight other RSGB representatives attending remotely. The meeting serves as both a celebration of amateur radio's rich heritage and a forward-looking forum to address the challenges and opportunities facing the global amateur radio community. You can view meeting documents at conf.iaru-r1.org  In celebration of the centenary of the IARU the RSGB has created a web page to share information about its part in the celebrations. This includes a link to an RSGB archive video from the IARU meeting in Paris in 1950, as well as the RSGB's July 1925 T & R Bulletin that contains an announcement detailing the formation of the IARU. Go to rsgb.org/iaru-centenary for further details. Today, Sunday the 27th of April, is World Morse Day. The day honours the birthday of the inventor of Morse code, Samuel Morse, who was born on this day in 1791. To celebrate the occasion, the RSGB has released a video with a question in Morse code for you to answer. Once you have used your Morse skills to decipher the question, get involved by leaving your answer in the comments section under the post. You can view the video on the RSGB YouTube channel via youtube.com/theRSGB or search for @theRSGB on Facebook or X. The deadline to apply to be the Team Leader for this year's Youngsters On The Air Summer Camp is Friday, the 2nd of May. This year's camp takes place between the 18th and 25th of August near Paris and is a chance of a lifetime for young RSGB members to represent their country and their national society. If you are an RSGB member, aged between 21 and 30, and are able to motivate a team of young people, then the RSGB would love to hear from you.

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

Hey everyone, Alex here

The increasing popularity of Asian food presents many exciting business opportunities, but also some challenges. Many of these specialty restaurants are family-owned, and lack the corporate structure you'll find at larger chains. And a lot of them are located in rural places that make centralized distribution difficult. Servicing these types of businesses requires a personal touch, and a lot of relationship building to understand their individual needs. That makes the barrier to entry pretty high, and creates a pretty large moat around the companies already established in the sector. That includes HF Foods Group, led by CEO Felix Lin. HF trades on NASDAQ under the symbol HFFG and they are a leading distributor of international and specialty foods service solutions to restaurants, wholesalers and other customers in the food supply chain in the United States. Before taking on the role of CEO, Felix served as President and Chief Operating Officer of HF Foods Group and has been a key part of developing, implementing, and executing on the company's comprehensive transformation plan. Felix joins us to discuss how HF Foods Group made such strong inroads in the Asian food market, and how they plan to leverage their position in the marketplace, and smart capital allocation, to create opportunities for future growth.

Hey everyone, Alex here

Hello, I'm Geoff Emery, VK4ZPP, and I've been thinking. Well the space weather is jostling us about with interesting solar activities over the past week. This is a great challenge for the DX chaser on the shortwave bands as conditions can vary in short order with coronal mass ejections causing ionising effects in the atmosphere. The next couple of days could be amazing as we get the benefits of solar flares which continue in this cycle. This is a rare happening when we have two consecutive long weekends, an occurrence which stirs the embers in many an Aussie chest. It seems that the gods of weather are being kind for Easter allowing people to enjoy their preferred activities with sunshine for a change. Whether the following weekend will be so fortunate as thousands gather to participate in the Anzac memorials, we will have to wait and see. One thing that has been filtering through my thinking is how little we seem to consider amateur radio and modern housing solutions. With more and more people living in apartments and suburban homes being erected on postage stamp sized allotments, the opportunity to maintain a reasonable working HF station is getting more limited. When we could look at a yard of 810 square metres as being the average, there was enough space to generally have some sort of antenna system. Whether it was horizontal such as the once ubiquitous G5RV, a doublet or a modest tower with a commercial beam, the options were available. Now many of the people who had these facilities have moved into smaller residences, maybe granny flats, apartments a few stories high and even supported accommodation. Each of these situations has its own set of limitations for a once active ham. Yes there is internet linked means and VHF and UHF repeaters but for the died in the wool HF operator it can be like losing an arm or a leg when they can no longer make the skeds with people they have known over the air. For the youthful person juggling study, work and perhaps romance, the proverbial dance card is already close to full and even although they may have enjoyed amateur radio when circumstances were different, they find themselves effectively isolated from the hobby. Mobile operations have always been an option for those fortunate enough to have access to a vehicle but many people don't have that option so home based operation is their only opportunity to stir the aether again. What I see is many people who could be more active but who are functionally denied access. The value of video sharing sites is good but I don't see much material aimed at the so-called house bound amateur. I don't get to see much of the current overseas magazines as they have disappeared from the newsagent shelves but from our own publication it seems authors aren't engaged is this side of the hobby. Perhaps clubs could think this over and find some ways forward. I'm Geoff Emery VK4ZPP and that's what I think…. how about you?

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

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

We are used to seeing depression one way: tears, extreme sadness, never leaving the house, pure misery. But for many of us, we experience depression differently. High functioning depression, a kind of depression where an individuals presents as seemingly 'fine' if not successful and thriving is on the rise. But despite outside appearances, it's just as debilitating as the depression we expect. In today's episode we discuss: The bad vs. sad stigma present in society What we expect depression to look like + why that harms people What HF depression really looks like What factors increase the likelihood The link between overachievers, childhood trauma + hyperindependence How to support a loved one with HF depression How to cope ourselves + so much more Listen now!

Foundations of Amateur Radio Recently I started an experiment I plan to run for a year. Using a WSPR beacon and a dummy load I'm transmitting 200 mW, 24 hours a day across all bands supported by my hardware, in this case it covers 80m, 40m, 30m, 20m, 17m, 15m, 12m, and 10m. The aim of the experiment is to determine if, and to what extent my dummy load can be heard outside my shack. Why? Because I've not seen anyone do this and because a dummy load is widely believed to not radiate, despite evidence to the contrary. Together with the transmission side, I've also configured an RTL-SDR dongle, initially with the telescopic antenna it came with, now, since my HF antenna isn't being used by the beacon, I'm using it instead. It's about five metres away from the beacon, outside. It's a helically wound whip resonant on the 40m band built by Walter VK6BCP (SK). It's what I've been using as my main antenna for the past seven years or so. While I'm telling you this, my beacon has been heard by my dongle 1,182 times across all eight bands. Some of those reports were from inside the shack, some from outside, some while I was monitoring a single band, and for the past week or so, I've been monitoring all the bands supported by "rtlsdr_wsprd", 18 in all. Purposefully, this includes some bands that I'm not transmitting on, because who knows what kinds of harmonics I might discover? The receiver changes band every half hour, so over time when I monitor a band will shift across the day, this is deliberate. I don't know when a stray transmission might suddenly appear and this will give me the best chance of hearing it, short of using 18 different receivers. At this time, my beacon hasn't been heard by any other station. I'm not expecting it to, but that's why I'm doing this experiment in the first place. I'm not in any way reaching any sense of "DX on a dummy load", but it got me thinking. My beacon can be heard, albeit by me, from five meters away. So it's radiating to some extent. I've already discussed that this might come from the patch lead between the beacon and the dummy load, or it could be the dummy load itself, or some other aspect of the testing configuration. Regardless of the situation, there is a signal coming from my beacon that's wirelessly being heard by a receiver. That's the same as what you'd hope to achieve with any antenna. So, in what way are an antenna and a dummy load different, and in what way are they the same? Whenever someone asks this, the stock answer is that an antenna radiates and a dummy load doesn't. My experiment, 20 days in, has already proven that this distinction is incomplete, if not outright wrong. Even so, if we take it on face value, and we say, for argument's sake, that a dummy load doesn't radiate and an antenna does, then how do we materially distinguish between the two? How does an antenna compare to a dipole, Yagi or vertical antenna and where does the isotropic radiator fit in this? The best I've come up with so far is a spectrum line comparing the various elements. Let's say that at one end of the spectrum is a dummy load, at the other is an isotropic radiator, to refresh your memory, that's the ideal radiator, it radiates all RF energy in all directions equally. Somewhere between the two ends is a dipole. We might argue if the dipole sits equally between a dummy load and an isotropic radiator, but where does a Yagi or a vertical fit in relation to the dipole? Also, if you turn a Yagi in the other direction, does it change place? So, perfect this notion is not, but here's my question. What's the measurement along the axis between the dummy load and the isotropic radiator? It's not SWR, since the ideal antenna and a dummy load share the same SWR, unless this line is a circle that I don't know about. It might be Total Radiated Power expressed in Watts, but that seems counter intuitive. It would mean that in order to determine the effectiveness of an antenna we'd need to set-up in an anechoic chamber, basically a warehouse sized room where incoming radiation is shielded to some predetermined standard. Do we measure gain using a VNA and call it a day, or is there something else going on? Remember, we're attempting to quantify the difference between a dummy load and an antenna. In case you're wondering, I'm asking the question. In the 15 years I've been part of this community, I've never seen any coherent response. The Internet seems to return a variation on the radiation vs. not-radiation pattern, but so far I've not seen anyone quantify this, or perhaps I haven't understood it while it was staring me in the face. I even checked the syllabus for the three license classes in Australia. The single reference that the regulator appears to specify is that at the introductory level you are required to, wait for it, recall that when testing a transmitter, a non-radiating load, or dummy load, is commonly used to prevent a signal from being radiated. Very illuminating. Obviously my dummy load is of the wrong type, the radiating variety. Which begs the question, if there's an ideal radiator, is there a theoretical ideal dummy load that doesn't radiate in any way, and if so, how far away on this line is it from my actual dummy load? Over to you. What are your thoughts on this? Better yet, got any references? I'm Onno VK6FLAB

Foundations of Amateur Radio Recently I received a question in relation to the Bald Yak project. If you're not familiar, "The Bald Yak project aims to create a modular, bidirectional and distributed signal processing and control system that leverages GNU Radio." I know that I've said that several times now and I suspect I'm going to say it several more times before we're done. I was asked about a specific radio and if this project could make it use a frequency that the supplied software didn't cover. The answer is deceptively simple and if you know me at all, you know what's coming: "It depends". As with many things, what it depends on is not fixed. I'll come back to the question, but I'm making a diversion past a magical place, the local hardware store. You can buy everything you need to build a house with the caveat that some assembly is required. GNU Radio is similar for building a signal processing system, but, wait for it, some assembly is required. In the context of GNU Radio this means that you'll need to collect all the bits and wire them together, fortunately you're unlikely to need Personal Protective Equipment or access to a First Aid Kit, unless of course the idea of playing with computers gives you palpitations, in which case I'd recommend that you go see your doctor. One of the less obvious things you'll come across with GNU Radio is how to bring signal processing into the physical realm, in other words, how do you get a signal into your computer, known as a "source", and get it out, called a "sink". The ability to talk to physical hardware arrives in roughly three different ways. Let's call them, "native", "library", and "abstraction". Native access requires that GNU Radio already knows about the hardware out of the box. Library access requires that the hardware manufacturer has provided software libraries, also known as drivers, allowing GNU Radio to communicate, and finally, abstraction is where a third party has written a library that knows how to talk to hardware from different manufacturers. The distinction between these is almost arbitrary, for example abstraction might require a driver from a hardware manufacturer. Similarly, because all this software is open source, native can include software from other projects, like the RTL-SDR blocks from Osmocom, Open Source Mobile Communications, and UHD blocks written by Ettus Research, which in turn can be seen as an abstraction. As I said, some assembly required. I will point out that this provides a great deal of flexibility, albeit at the cost of complexity, there's still no such thing as a free lunch. At this point you might shake your head and run away. I get that, it can be daunting. Before you do, consider the scenario where you have a working system and you upgrade your hardware. In a GNU Radio world you'll need to figure out how to configure the new hardware and then all your other stuff will continue to work. The alternative is upgrading each of your applications to connect to your new radio and in doing so, run the risk of making your old radio obsolete, even if you are collecting them .. let's say for posterity rather than hoarding .. because radio amateurs never hoard anything .. right? Back to the original question. Can GNU Radio make a radio use frequencies that the software that came with the radio cannot? As I said, "it depends". First of all, the hardware needs to actually be able to support the frequency. Then someone needs to have written a library to use that frequency, then GNU Radio needs to be able to use that library. That said, the chances of that happening are much higher than the chance of the hardware manufacturer rolling out this feature within your lifetime. Before you start yelling at me, yes, this is manufacturer dependent, some provide open source tools, many still don't. There are alternative ways to access different frequencies. The PlutoSDR is a computer and radio in a box. You can connect to it, change some settings and have it access a whole lot more frequencies. In some ways it's like adding or removing jumpers on a traditional circuit-board. Another approach is to use an up- or down-converter. Essentially a piece of hardware connected between antenna and radio that translates frequencies to different bands. A down-converter allows you to use the 23cm band on a radio that's only capable of 70cm. Similarly, an up-converter allows your 70cm radio to hear HF signals. If you see a symmetry here, you didn't imagine it. You need both to transmit and receive, sold together in the same box as a transverter. Just so we're clear, the radio is still using the 70cm band, but the RF coming in and out of the antenna connected to the transverter is on a different band entirely. It's why my Yaesu FT-857d has three menu options, 89, 90 and 91, to adjust the display to show the actual RF frequency. As an aside, you could use this functionality if your radio is off frequency by a known amount. As I've said before, GNU Radio is a powerful tool. It contains many different moving parts, the system is complex and unwieldy, but with it comes the promise of doing some amazing stuff. The whole point of the Bald Yak project is to make this all accessible to the wider amateur community, not just computer geeks and software radio nerds. If you have questions, feel free to drop me a line. I'm Onno VK6FLAB

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."

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. This is Graham Kemp VK4BB.(MILLENNIUM POST)**BROADCAST TRADE SHOW DROPS RECEPTION FOR HAMSPAUL/ANCHOR: Hams will no doubt be among those visiting the National Association of Broadcasters annual trade show again this year but something will be missing, as we learn from Ralph Squillace KK6ITB.RALPH: The annual trade show of the National Association of Broadcasters is welcoming industry professionals once again this year to Las Vegas in April. 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. The NAB Show takes place between April 5th and 9th at the Las Vegas Convention Center.This is Ralph Squillace KK6ITB.(RADIO WORLD)**BREAK HERE: Time for you to identify your station. We are the Amateur Radio Newsline, heard on bulletin stations around the world including the WB3GXW repeater in Silver Spring, Maryland and simultaneously on EchoLink Conference Server Node 6154 on Saturdays at 8 PM and Sundays at 7 PM Eastern time.**DX INDIA FOUNDATION PREPARES FOR DXPEDITIONNEIL/ANCHOR: In India, there's a new DX foundation that has lots of energy and ambition - and plans for a rarely activated island. 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. He is using the callsign 8P9CB, operating SSB and CW on 20-10 metres. Some of his locations are POTA sites. See QRZ.com for QSL details.Rockwell, WW1X, is using the callsign VP5/WW1X from Providenciales, IOTA Number NA-ØØ2 in the Turks and Caicos Islands from the 8th through to the 15th of March. This is a QRP operation using only SSB, although Rockwell has not ruled out occasional use of FT8. QSL via LoTW.Listen for Aldir, PY1SAD, who is using the callsign 8R1TM from Georgetown, Guyana, between the 11th of March and the 26th of April. Aldir is using CW, SSB and the digital modes on the HF bands. He is also operating via satellite. See QRZ.com for QSL details.Members of the Korean Amateur Radio League are on the air in March and April to celebrate the centenary of the International Amateur Radio Union. They are using the callsign HL1ØØIARU. See QRZ.com for QSL details.(425 DX BULLETIN)**KICKER: ECHOES OF A DIFFERENT WAY TO LEARN CWPAUL/ANCHOR: We end this week's report with an alternate way in which some hams in New Zealand got to learn and practice CW while having real QSOs. 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?

Færre unge skal gå på gymnasiet, som vi kender det i dag. I stedet får de unge en ny og mere praktisk orienteret gymnasial uddannelse, EPX. HF og de kommunale 10. klasser lukkes, samtidig med at adgangskravene til de almene gymnasier hæves fra 5 til 6. Det er blevet klart med den nye uddannelsesreform, som netop er landet.

This week, we've got the final file from Felix's Hong Kong adventure, and we've undoubtedly saved the best til last. Zoë Abelson, better known on Instagram as @watchgirloffduty has built a life and a career hunting down rare timepieces. These days that business has coalesced into Graal Watch, which makes her the perfect person to find that obscure reference. We chat with Zoë about the pros and cons of hunting other people's grails and explore the ambiguities implicit in the watch dealers' role as tastemakers, as well as what those tastes are looking like today: pro tip — smaller watches are where it's at. Before all that, Andy and Felix tackle the thorny issue of giving Andy's dad a watch. Let us know in the comments what you think that watch was.  Interview with Zoe Abelson (11:56) Graal Watch Zoe Abelson on Instagram Zoë Abelson at HF.10's ‘Whose Birkin is it Anyway' panel Like watches?
