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

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.

Now the contest news On Tuesday the 22nd of April, the SHF UK Activity Contest runs from 1830 to 2130UTC. Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator. On Thursday the 24th of April, the 80m Club Championship runs from 1900 to 2030UTC. Using PSK63 and RTTY, the exchange is signal report and serial number. The UK and Ireland DX CW Contest starts at 1200UTC on Saturday the 26th of April and ends at 1200UTC on Sunday the 27th of April. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. UK and Ireland stations also send their district code. 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.

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.

GB2RS News Sunday the 27th of October The news headlines: The RSGB releases a snapshot video of the exciting Girlguiding ISS contact You can listen to the Chair of the RSGB's Propagation Studies Committee on the latest episode of the ICQ podcast The RSGB has begun releasing presentations from its 2024 Convention On the 5th of October, in her first official engagement as Girlguiding Patron, Her Royal Highness The Duchess of Edinburgh joined 100 excited Brownies, Guides and Rangers in making a live amateur radio contact with the International Space Station. The event was organised by The Radio Society of Great Britain and Amateur Radio on the International Space Station, or ARISS as it is usually known, in collaboration with the UK Space Agency, Girlguiding Surrey West and Brooklands Museum's Innovation Academy programme. The aim was to promote the engagement and involvement of girls and young women in science, technology, engineering and mathematics. Everyone had a fantastic day and after the contact, the girls enjoyed a variety of STEM activities including making Snail Morse keys, playing Morse battleships, learning about the CubeSat Simulator and making stomp rockets. The RSGB has created a short video snapshot of the day which you can see on its YouTube channel at youtube.com/theRSGB – take a look! The latest episode of the ICQ Podcast is available to listen to online and features RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. During episode 441 Martin Butler, M1MRB talks to Steve about propagation and how the sunspot cycle has taken off to impact conditions positively. They also discuss Ham Radio Science Citizen Investigation, which is also known as HamSCI, a collective that enables university researchers to collaborate with radio amateurs in scientific investigations. To access the interview, select episode 441 at icqpodcast.com and listen from 1 hour and 35 minutes. The RSGB 2024 Convention weekend brought together hundreds in person and thousands via the livestreams. As well as the ‘Convention in a nutshell' video released last week, the Society has now published two of the main presentations. The first is the keynote speech about the future of amateur radio licensing and education by Rafal Lukawiecki, EI6LA. The second looks at inspiring the next generation by the RSGB's two new Youth Champions Chris Aitken, MM0WIC and Rhys Williams, M0WGY. You will find both presentations, as well as the full two days of live stream content, in the RSGB 2024 Convention playlist on the Society's YouTube channel. Remember to subscribe to the channel so you don't miss additional presentations when they're published. There is also still time to share your feedback about the in-person event or the live stream, but the feedback forms will close at the end of this month. Head over to rsgb.org/feedback if you attended the event, or rsgb.org/livestream-feedback if you watched via the livestream. Let the team know what you enjoyed! If you are thinking of taking an amateur radio exam before Christmas, there are two important dates you need to be aware of. The last date you can take an exam at a club, whether online or on paper, is Friday the 13th of December. If you want to take an exam online at home, the last date you can do that is Friday the 20th of December. The RSGB Exams Team will, where possible, post-out exam results before HQ shuts over Christmas and New Year. Exams will resume on Monday the 6th of January 2025 and the booking system will be available over the festive season so you can book exams for January onwards. You can book online on the RSGB website at rsgb.org/exampay On Friday the 18th of October the RSGB, Mill Hill School and a team of radio amateurs in New Zealand took part in a special celebration to mark the centenary of the first successful two-way trans-global communication between radio amateurs in the UK and New Zealand. The original contact between Frank Bell, 4AA in New Zealand and Cecil Goyder, 2SZ in Mill Hill School in North London was re-enacted at the school on a wavelength as close as possible to the original. Members of Goyder's family watched the re-enactment and chatted to pupils. As part of wider celebrations for the day, the school put on activities including a build-a-radio workshop. Students at the school showed significant interest in amateur radio, with several students signing up to be part of a new radio club that will be set up by the school's physics teacher. The overall event was led by RSGB Life Vice-President Don Beattie, G3BJ who said that he was delighted by the success of the event and that it had allowed pupils to learn how ground-breaking that first radio contact was with New Zealand. Call sign G2SZ was operational for four days surrounding the centenary, during which operators achieved approximately 1,250 contacts. To find out more about this unique celebration go to www.gb2nz.com and search for ‘GB2NZ re-enactment' on the RSGB website. The Memorial Day QSO Party is an activity providing participants with an opportunity to honour amateur radio operators who are now Silent Key. The event is being sponsored and managed by the First Class CW Operators' Club and is open to all licensed amateurs. The event begins at 0900UTC on the 1st of November 2024 and ends at 0859UTC on the 2nd of November. More information is available at g4foc.org or by emailing mdqp@g4foc.org or michelecarlone@yahoo.it Ofcom has notified stakeholders that the next release of its licensing service will be delayed due to issues that have arisen during software development. According to the Ofcom website, the delays have impacted Phases 2 and 3 of the planned changes to the amateur radio licensing framework. Phase 2 includes changes to new Intermediate callsigns, special event station rules and restrictions on the number of callsigns an individual may hold. Revised plans are expected to be published soon.

More information about the contest and the award programme are available at iparc.de  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 24th of October 2024 Last week's solar conditions couldn't have been much better. We had a week of high solar flux indices, relatively calm geomagnetic conditions and, other than an X-class solar flare, not much else to report. The solar flare originated from active region 3869 and reached a strong X3.3 in the early hours of October 24th. This event was associated with a coronal mass ejection, or CME, based on solar dimming following the event, but because the flare location was located off the east limb, it was directed mostly away from Earth. Once again, all the sunspots are in the southern hemisphere, but activity appears to be growing. This could spell trouble over the next week. This weekend, the 26th and 27th, the CQ Worldwide SSB contest is taking place and conditions should be excellent, with a combination of high solar flux and autumnal HF conditions. Maximum usable frequencies, or MUFs, are generally higher than 28MHz from dawn until dusk. Nighttime MUFs over 3,000km are still just above 14MHz, although you might get better results by dropping down to 10MHz if the 20m band doesn't work for you. Next week, NOAA predicts that the solar flux index may rise again, perhaps hitting 185 as we enter November. However, this current bunch of sunspots, which are rotating to be Earth-directed next week, appear more active and we could see more solar flares and CMEs, which could throw a spanner in the works. A solar flare could impact the ionosphere by increasing D-layer absorption, for up to an hour or so, and possibly launch a coronal mass ejection. If a CME hits the Earth, expect the MUF to plummet, at least for a day or two until the ionosphere recovers. And now the VHF and up propagation news from G3YLA and G4BAO The Autumn Equinox period brought some amazing ionospheric propagation to 50MHz on Thursday last week with stations in the UK working morning paths to VK, JA, DS and XV among others. Typically for 50MHz DX, the skip zones were sharp and moved rapidly. Stations even a few kilometres apart experienced very different signals and paths. Those with a low noise floor had a huge advantage as signals were generally weak in the UK and only good for FT8. However, some reports of a VK station at +5 bucked this trend. Next week will offer some reasonable Tropo conditions, although not without some occasional interruptions from weak frontal systems, especially in the far southwest and the far northwest of Britain. It's not clear if these represent good rain scatter options, but they are more likely to temporarily curtail any Tropo for a while. The solar conditions continue to feed the occasional aurora alert our way, so it's always good to monitor the Kp index for signs of it increasing above 4. It won't always go on to produce a radio aurora, but it's worth keeping an eye on things. The meteor scatter prospects continue to be elevated by the decline of the Orionids, which peaked on Tuesday the 22nd, and the Taurids, which are a very low-rate shower, but technically cover a broad period into December. The Leonids are the next major shower, but that doesn't peak until mid-November. Lastly, looking at the out-of-season Sporadic-E prospects, there are always days with minor enhancements of the critical frequency of the Sporadic-E layer, as shown on the propquest.co.uk graphs. Certainly, there are stronger jet streams available in the autumn and winter, but other elements of Sporadic-E are not so favourable. It's usually a very marginal outcome at best, but good enough for the 10 or 6m bands and mostly for digital modes such as FT8.  It could well be that trans-equatorial propagation, or TEP, is a more fruitful venture. For EME operators, Moon declination is positive, but falling, going negative on Tuesday the 29th. Path losses are rising, reaching a maximum at apogee on the morning of Wednesday the 30th. 144MHz sky noise is low until Friday the 1st of November when the Sun and Moon are close in the sky. And that's all from the propagation team this week.

The Solar Eclipse QSO Party (or SEQP), is an on-air event coming up on April 8, the same day as the next total solar eclipse. The SEQP is a great opportunity for hams to contribute data to studies of Earth's ionosphere, the part of our atmosphere that makes radio communications possible, and all you have to do is get on the air and operate as you normally would. The lead organizer of HamSCI, Dr. Nathaniel Frissell, W2NAF, joins us in this episode to explain how to get involved.

Foundations of Amateur Radio Have you ever had a day when nothing you started actually got anywhere? I've had a fortnight like that. Several weeks ago I wrote a couple of articles about emergency communications and its tenuous relationship with our hobby. As a result I managed to get a week ahead of myself and started using that week to do some long overdue analysis of the WSPR or Weak Signal Propagation Reporter data set. I've started this process several times and I finally had a whole fortnight to come to grips with 6.7 billion rows of data. Spoiler alert, it hasn't happened yet. The data contains a record of every reception report uploaded to WSPRnet.org since Tuesday 11 March 2008 at 22:02 UTC. It's published in compressed comma separated value text files and after previously spending weeks of wrangling I managed to convert each one into an sqlite3 database. This wrangling was required because some amateurs used commas in their callsigns or grid squares, or backslashes, or both, and SQLite import isn't smart enough to deal with this. After doing this conversion, I could actually query 191 different databases. I could collect the results and three weeks later I'd have an answer, just in time to download the next month of data. Garth VK2TTY suggested that I look into parquet as an alternative. No joke, This Changed My Life. I managed to convert all the compressed CSV files to parquet, a process that took a day, rather than a week with SQLite, and then I could start playing. If you're going to do this yourself, make sure you have a big empty hard disk. After a few false starts, the report that previously took three weeks, returned in three hours, and if we're getting technical, since I know this will make at least somebody laugh, the parquet files are stored on a USB drive connected to an iMac that has the directory mounted via sshfs to a virtual Linux desktop machine that's running the duckdb binary inside a Docker container running on a different virtual Docker machine. If you're keeping track, the database travels across USB via two SSHFS mounts to duckdb and it still only takes three hours. So, impressed doesn't even begin to describe my elation. If you're asking "why?" - the answer is that I don't run untrusted binary executables on my host machine. This allowed me to start doing what-if queries when I discovered a fun issue. A chart I generated with minimum, average and maximum power levels over time showed that there was at least one station that was claiming that it was transmitting with 103 dBm. For context, that's multiple times the power of HAARP, the High-frequency Active Auroral Research Program which in 2012 was the most powerful shortwave station using "only" 95.5 dBm, or 3,600 kilowatts, and only 2 dBm shy of the 105 dBm or 32 megawatts used by AN/FPS-85, part of the US Space Force's Space Surveillance Network, able to track a basketball-sized object 41,000 km from Earth. In other words, 103 dBm is less of a whisper and more of a roar. Funnily enough, not every receiver on the planet reported these transmissions, but more than one did, so the issue is at the transmitter. Unfortunately, when I started looking for reports using more than 60 dBm, there were plenty to choose from, over 18 thousand. While that's less than 0.0003%, it made me wonder how much of the data is dirty and what should I do about it? There's other examples of dirty data. My beacon has been reported on 24 MHz, which is odd, since my licence conditions do not permit me to use that band. Odder still is that several other beacons, normally on 28 MHz like me, were also reported on 24 MHz by the same station. How often does that happen? I've previously reported the missing data from the hybrid solar eclipse in 2023, just under two hours and 12 minutes before the eclipse and the 38 minutes following it was missing. I've not yet checked to see if it magically reappeared. Then there's the faulty decodes. I've talked about this before. Different WSPR versions are better or worse at decoding and the point at which it breaks down varies. In other words, some decoded data is inevitably wrong. I have previously charted activated grid squares. Apparently, all of Earth, yes, all of it, has at one time or another been used both as a transmission or reception site. Including point Nemo, the top of Mount Everest, all of the arctic and antarctic and plenty more out of the way places, like say the Surveyor Generals Corner located in the Ngaanyatjarraku shire - look it up. Interesting patterns emerge when you split activations down per band. It's not clear if those are decoding artefacts or man made claims. I've asked the HamSci community for guidance, since dropping incorrect data on the floor doesn't seem to be the right way to go about things, and whilst correcting data seems obvious, what do you change it to and how do you know what's correct? So, no progress to show for two weeks of work and barely enough to whet your appetite to get on air and make some noise. Some days are like that. I'm Onno VK6FLAB
