GB2RS News Sunday, the 15th of February 2026 The news headlines: Support the RSGB Contest Committees Learn your freedoms and restrictions in relation to repeaters, gateways and packet radio in March's Tonight@8 Check your club's details are up to date on Club Finder The RSGB Contest Support Committee, HF Contest Committee and VHF Contest Committee are looking for volunteers who can help organise, support and manage the Society's contesting activities. While applications from experienced contestants are welcome, the committees would also be pleased to hear from radio amateurs who are new to contesting. If you are interested in volunteering, please contact RSGB General Manager, Steve Thomas, M1ACB, in the first instance, via gm.dept@rsgb.org.uk In February 2024, Ofcom made significant changes to the amateur radio licensing conditions, but how has that affected your freedoms and restrictions in relation to repeaters, gateways and packet radio? In the next episode of Tonight@8, two members of the RSGB Emerging Technology Coordination Committee will answer this question for you. Join Steve Morton, F4VTF and John McCullagh, GI4BWM, live on Monday, the 2nd of March, via the RSGB's YouTube Channel or via its special BATC channel. If you have a question on this topic, ensure you watch the webinar live and submit your question via the live chat feature. Find out more by going to rsgb.org/webinars If you are a member of an RSGB-affiliated club or society, the RSGB is encouraging you to check that your organisation's details are up to date on Club Finder. The RSGB Club Finder allows people to search for local amateur radio groups. Those people could want to join your club, find out more about amateur radio before taking their Foundation licence exam, or perhaps need support for British Science Week activities. Updating your listing is easy. Just log in to your club's Membership Services account and go to the ‘UK Club Finder' section. The form includes a section called ‘Meeting details' where you can add helpful information about disabled access, as well as details about both physical and online meetings. The Society will update Club Finder with any new data between 4 pm and 6 pm every Friday. If you wish your latest information to appear before the weekend, please ensure you update your details before 3 pm on Fridays. If you have any questions about the process, please contact membership@rsgb.org.uk Among the many informative and engaging displays at the RSGB National Radio Centre, you'll find information highlighting the contribution to the war effort made by Voluntary Interceptors who were RSGB Members during World War Two. It is this topic that Josephine Saunders explores in her compelling article “Listening for victory” published in “BRITAIN” magazine. The four-page feature looks at the role that radio amateurs played in the War, and how RSGB volunteers now help to bring this history to life at the RSGB National Radio Centre. She also looks at some of the wide-ranging activities on offer at the NRC, such as the ‘Find the spy transmitter' event held last year. Subscribers to the magazine can read the feature on page 63. It can also be read by going to tinyurl.com/NationalRadioCentre Participation from radio amateurs in this year's British Science Week is already looking to exceed last year's. Several clubs and groups are looking to set up skeds, ranging from South Derbyshire and Ashby Woulds Amateur Radio Group to Crowthorne and Wokingham Without NMI Men's Shed. A sked is a prearranged radio contact with another radio operator at a scheduled time and on a particular frequency. Find out more about these opportunities by going to rsgb.org/bsw and selecting ‘Events happening near you' from the right-hand menu.

Using SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. On Sunday, the 22nd of February, the UK Microwave Group EHF Band Contest runs from 0800 to 1700 UTC. Using all modes on 76 to 241GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday, the 12th of February. It has been a good time for HF DX. Settled geomagnetic conditions and a fairly high solar flux index has meant the ionosphere has had time to shine. With the Kp index not exceeding 4.33, and generally being in the ones and twos, coupled with a solar flux index in the 160s, this has meant that the upper HF bands have been humming. This is despite many relatively minor C- and M-class solar flares. DX heard or worked this week includes stations in Vietnam, India, Australia and New Zealand on the 10m band, even with modestly equipped stations. DX being chased includes the KP5/NP3VI Desecheo Island DXpedition near Puerto Rico. This has been difficult, often because they are running low power on their remotely controlled rigs. But UK stations have got through on all bands from 40 to 10m. Due to deteriorating sea conditions, they have delayed equipment recovery until the 3rd of March, so you still have time to work them. The next big DXpedition to look forward to is 3Y0K from Bouvet Island. Due to technical problems with their ship, the operation has now been delayed and will start around the 26th of February. With the path to Bouvet being almost due south from the UK, propagation predictions suggest that the path should be open from around 0730UTC until 1830UTC, up to 10m, with 21MHz being open from around 0800 to 1000UTC and again from 1600 to 1800UTC. Outside of these times, look for a path on the 20, or even 30 or 40m bands, in the evening and night. FT8 will be the most favourable mode, but CW and SSB are possible. However, remember they will be using split frequency operation. Next week, NOAA predicts that the solar flux index will increase to be in the 160 to 180 range. Geomagnetic conditions may start the week settled, with a predicted Kp index of 2, but we may expect more unsettled conditions as the week progresses, with a predicted Kp index of 4 from the 16th to the 21st of February. So, get your HF Dxing in early next week! And now the VHF and up propagation news from G3YLA and G4BAO The weather is often described as blocked when we see long-lasting high pressure, which hangs around for weeks at a time and is a gift for tropo on VHF. However, right next door to a blocked high you will probably find a low-pressure region, which is also blocked for the same reason. Currently, we are in the middle of a prolonged period of blocked low pressure, hence the rain and absence of tropo. The position of the low varies a bit, of course, so sometimes we will have milder southerly winds with rain and at other times colder northerlies with snow. We have the full variety in the coming week or so, and that means no tropo for VHF operators, but plenty of rain scatter for the GHz folk. The meteor scatter position hasn't changed since last week's news, so we are once again confined to random activity and, for this, early morning hours are usually best. Aurora alerts continue to trickle through, and as we approach the spring equinox, the chances of auroras improve, but there is a little way to go yet. Lastly, thoughts of Sporadic-E remain dormant since we are some way short of the typical early season openings of late April and May. As usual, consider checking the propquest.co.uk graphs occasionally, which have shown minor peaks of the foEs, or critical frequency of the Es layer, in the early evening on some days. The Moon reached perigee, its closest point to the Earth, on Tuesday, the 10th of February. The Moon is moving toward apogee on Sunday, the 22nd of February, meaning path loss will gradually increase throughout the week as the Moon's distance grows. Cosmic background noise is relatively low during this period, which helps maintain a better signal-to-noise ratio. And that's all from the propagation team this week.

GB2RS News Sunday the 8th of February 2026 The news headlines: RSGB member-exclusive DDS programming workshop in Blackpool What are your British Science Week plans? Submit your RSGB 2026 Convention ideas As part of the Society's strategy to support radio amateurs in developing their practical skills, the RSGB will be running a DDS programming workshop in Blackpool on Saturday, the 11th of April, the day before the NARSA Rally. The six-hour workshop, which was first run at the RSGB 2025 Convention, is intended for RSGB members who already have a basic knowledge of Arduino programming. Attendees will learn how to control and program a Direct Digital Synthesiser using a microcontroller and will use this to generate RF. As well as covering the maths behind the programming process, attendees will also gain an insight into vibe coding. So, if 2026 is the year you want to take your programming skills up a notch, this is the event for you. For full information and booking details, visit rsgb.org/practical-events This year's British Science Week runs from the 6th to the 15th of March with ‘Curiosity: what's your question?' as its theme. Several clubs, youth groups and schools have already planned events and activities, and the RSGB's team of Champions are working together to deliver more. You can take part by trying one of the great activity suggestions that the RSGB has on its website. You could get your local WI, Men in Sheds group, school or youth groups or even your own family involved. If you have your own ideas, let the RSGB know; they don't need to be ‘grand', simply demonstrating the magic of radio is enough. Another way to get involved with British Science Week is by taking part in a sked, which is a pre-arranged radio contact with another radio operator at a scheduled time and on a particular frequency. The RSGB National Radio Centre is offering groups and clubs the opportunity to arrange a sked and get its sought-after GB3RS callsign into the logbook. To take part in this unique offering, go to rsgb.org/bsw and select ‘Events happening near you' from the right-hand menu. Contacts must be arranged in advance and would take place between 10 am and 4 pm during British Science Week. Is there a particular topic you'd like to learn more about at the RSGB 2026 Convention in October? Have you been working on some research or a project that you'd like to share with the amateur radio community? Or would you like to see a workshop explaining a new skill you'd like to try? Whatever the idea, submit your proposal to the RSGB by sending the title and at least a one-paragraph summary of your suggestion to convention@rsgb.org.uk If you're not yet an RSGB member and are curious to read RadCom Basics or RadCom Plus, take a look at the RSGB app, which is available for mobile and web. The RSGB has just released a sample edition of each, so whether you are a newcomer or are looking for more technical features, the samples will give you a taster of the Society's digital RadCom supplements. There are only three weeks left until the closing date for entries in the RSGB Construction Competition. The competition is open to all RSGB members and has six categories to enter, ranging from 'Beginners' to 'Construction Excellence'. Whether you are taking your first steps in construction or it is your 50th project, the Society invites you to get involved and be in with the chance to win a cash prize. Find out more by going to rsgb.org/construction-competition. The deadline for entries is the 1st of March 2026. The RSGB has several Regional Team vacancies, including District Representative positions in Hampshire, Leicestershire and Rutland, South Derbyshire and South Nottinghamshire, and also North Lincolnshire. This is an opportunity not only to support the work of the RSGB but to provide help and guidance for local radio amateurs and groups in your area. To find out how to apply or to view other Regional Team vacancies in other areas, go to rsgb.org/volunteers The RSGB is delighted to hear that Wick High School in Scotland is preparing for an ARISS contact later this year. The RSGB School Youth Chair, Chris Aitken, MM0WI,C is the Computing teacher at the school and also runs the school's amateur radio club, GM0WHS. Chris shared the news with the Society, and you can read more by going to rsgb.org/school-zone Please send details of all your news and events to radcom@rsgb.org.uk.

Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and serial number. PA stations also send their province reference. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 5th of February Last week was characterised by a high solar flux index but with a succession of X-class solar flares from active region 4366 on the Sun. Luckily, none of these resulted in a coronal mass ejection, so we got away lightly. The solar flux index stood at 178 on Tuesday, the 3rd of February, with the result that the 10m band was humming. US states logged included Oregon, Nevada, California, Washington and Idaho, all between 1530 and 1730UTC. As we always say, look for a high solar flux index and a low Kp index for DX – in this case, a Kp index of between 1 and 2.33. By comparison, the next day was a washout, possibly thanks to a Kp index increase to 3.67, thanks to a coronal mass ejection, or CME, that passed Earth at 1506UTC. Poor conditions continued on Thursday, the 5th, when the solar wind speed increased to more than 500 kilometres per second, the Kp index increased to 5.33, and maximum usable frequencies across a 3,000km path struggled to exceed 20MHz. Incidentally, February and March are good months for 10m band paths to the US. By April, paths start to drop away and start favouring South America, so if you need US states for your Worked All States award, now is the right time! In the meantime, keep an eye on active region 4366 as it may still have a sting in its tail. This monstrous sunspot group, 15 times the width of Earth, was Earth-centric on Thursday, the 5th. As always, we recommend visiting solarham.com for daily updates on space weather. Next week, NOAA predicts that the solar flux index will be in the 130 to 150 range, although the Kp index might be unsettled at times, with an average Kp index of 3. Friday, the 13th of February, is forecast to be particularly unsettled with a Kp index of 5. And now the VHF and up propagation news from G3YLA and G4BAO The markedly unsettled weather pattern continues to bring a mix of rain and showers and very strong winds at times, plus the threat of snowfall in some eastern and northern areas. This probably means that tropo will be hard to find during the coming week but leaves us with plenty of chances for rain scatter for GHz operators. In the solar-terrestrial domain, the disturbed Sun has once again brought a sequence of flares and coronal mass ejections, or CMEs, which has provided frequent auroral alerts as the Kp index has climbed to 4 or more. Listen for fluttery signals on the LF bands and perhaps ghostly sounding signals on HF and VHF, typically 10m to 2m. Meteor scatter operators must rely upon random meteor activity, but over the whole Earth, this can amount to 25 million meteors or meteoroids per day, so there is every chance that even random activity could produce a path for you if you have a quiet site. The mix of meteor activity and a low Kp index can lead to out-of-season Sporadic-E, given some jet stream weather activity. However, this is currently well south of the Mediterranean in its usual winter position, so any Sporadic-E may be a bit too far south to reach from the UK in the short term. This week, Moon declination is negative all week and falling until Thursday, the 12th of February. Moon window length and peak elevation follow suit. Path losses are rising again as we reach apogee, the Moon's furthest point from Earth, on Tuesday, the 10th of February. 144MHz sky noise is low but rising to high by Thursday, the 12th of February. And that's all from the propagation team this week.

This week's Tech Field Day News Rundown dives into the biggest AI, security, and enterprise shakeups. Tom Hollingsworth and Alastair Cooke deliver this week's Tech Field Day News Rundown, starting with a global push by actors and musicians calling for a “permission-first” approach to AI training, as unions accuse AI companies of using copyrighted works without consent. They also cover growing security concerns around agentic AI after researchers discovered serious vulnerabilities in MCP servers from Anthropic and Microsoft. Snowflake and OpenAI's $200 million partnership to bring governed, production-ready AI into the enterprise data cloud, mounting financial pressure on Oracle with potential mass layoffs and a possible sale of Cerner, high-severity vulnerabilities in the n8n AI automation platform that allow remote code execution. They also discuss a critical Broadcom Wi-Fi chipset flaw capable of taking entire 5 GHz networks offline and new warnings from researcher Jason Meller about AI agent “skills” being weaponized as malware—highlighting how quickly AI ecosystems are evolving into both powerful business tools and major security risks.This and more on the Tech Field Day News Rundown with Tom Hollingsworth and Alastair Cooke.

Now the contest news The CQ World Wide 160m DX Contest started at 2200UTC on Friday, the 23rd and runs until 2200UTC today, Sunday, the 25th of January. Using CW on the 160m band, the exchange is signal report and CQ Zone. American stations also send their state, and Canadian stations send their province. The British Amateur Radio Teledata Group Sprint started at 1200UTC yesterday, Saturday the 24th and runs until 1200UTC today, Sunday the 25th of January. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is your serial number. On Tuesday, the 27th of January, the RSGB SHF UK Activity Contest runs from 1930 to 2230UTC. Using all modes on the 13cm band, the exchange is signal report, serial number and locator. On Wednesday, the 28th of January, the United Kingdom and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 22nd of January 2026 Last week featured a massive aurora that couldn't have been predicted in the previous report. The cause was a large Earth-directed coronal mass ejection on Sunday, the 18th of January at 18:08 UTC. The solar wind speed was above 1,100 kilometres per second, so the impact on the Earth arrived sooner than expected. The result was that the Kp index rose to 8.33 at around 1938UTC on Monday, the 19th, sparking widespread aurora. Such was its intensity that the aurora was visible from Devon, and the Kp index was still at 8 the following day. HF was badly affected with maximum usable frequencies over a 3,000km path, struggling to reach 14MHz on the 20th of January. Luckily, things have now calmed down, but it shows that it is worthwhile keeping an eye on solarham.com for daily updates. HF DX was a little sparse during the height of the geomagnetic storm, but has since recovered. 8Q7JI in the Maldives was reported as being worked on the 20m band using FT8 in the afternoon of Wednesday, the 21st of January. The KP5/NP3VI Desecheo Island DXpedition continues and has been worked from the UK by better-equipped stations. 9X2AW in Rwanda will be operating for the coming two weeks. Lastly, VP2EIO in Anguilla is active until the 31st of January using FT8 and some SSB. NOAA predicts that the solar flux index will start next week around 175, but decline to 165 by Friday, the 30th. Geomagnetic conditions are forecast to be reasonable, at least until the 28th, when we may expect a Kp index of 4 or 5 over a three-day period. And now the VHF and up propagation news from G3YLA and G4BAO The mild unsettled weather is probably going to transform into a cold unsettled pattern during the next week. However, things will stay essentially unsettled with active weather fronts or heavy showers bringing plenty of opportunity for rain scatter on the GHz bands. After the good auroral and auroral-E propagation on the VHF bands early last week, we are in quieter territory now. However, as usual, a daily check on the Kp index will ensure you keep in touch with any sign of a recurrence. As for meteor scatter, we are now firmly in the random meteor period for several weeks and, with no major showers available, the best times will usually be in the early hours before sunrise. Lastly, a mention of Sporadic-E, which might crop up as brief spikes on the propquest.co.uk graphs. The foEs values in January show as isolated peaks from 5 to 7MHz, which is approximately equivalent to 10m and 6m. Perhaps a good way to see where the prospects exist is by using dxmaps.com to find current Sporadic-E paths on the 10 and 6m bands. A second hint can be found by looking at the Sporadic-E blog tab on Propquest to see where the main weather jet streams are located. This is because Sporadic-E paths are often associated with jet streams, especially where they cross mountain ranges like the Pyrenees or Alps. July this year sees maximum Moon declination coinciding with lowest path losses in the northern hemisphere, so there's never been a better time to try EME operating. This week, Moon declination is positive and rising, so Moon window length and peak elevation are increasing. Path losses are falling as we approach perigee on the 29th of January. 144MHz sky noise is low, rising to moderate on the 29th of January. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 8th of January 2026 Now that the dust has settled after the New Year's celebrations, we can get back to our regular propagation reports. The New Year has started with minor disturbed geomagnetic conditions at times, plus lots of C-class solar flares, and a healthy dose of sunspots. As we slide down the slope towards sunspot minimum, we can expect more geomagnetic disturbances and raised Kp indices. But we should still have good HF conditions for a couple of years. The Kp index hit 5 on the 2nd of January, but has otherwise been relatively quiet, often registering less than 1 or 2. And the lack of M- and X-class solar flares means we have had no solar fade-outs. With the solar flux index at more than 150 for much of the time, this bodes well for HF propagation and, as Propquest shows, the maximum usable frequency over 3,000km during daylight has often been more than 28MHz. Unfortunately, this does decline quite quickly after sunset, leaving the maximum usable frequency below 10MHz most of the time. As we head towards spring, we can expect this to improve. DX has been available. Stations worked include V51WH in Namibia on the 12m band using SSB, TZ4AM in Mali on 30m using CW, and ZS7ANF in Antarctica using CW on the 17m band. Next week, NOAA predicts that the solar flux index will be in the 130 to 150 range. Geomagnetic conditions are forecast to be variable, with the Kp index predicted to hit 5 on the 13th and 14th of January, and again between the 17th and 20th of January. So, we recommend you get your HF DXing in before the 13th and around the 15th and 16th, as propagation and maximum usable frequencies will no doubt be affected if the Kp index rises. With the three-week 3Y0K Bouvet Island DXpedition set for early February, now may be a good time to sort out your antennas. Remember that Bouvet is almost due south from the UK, so plan accordingly. More propagation details will be made available nearer the time And now the VHF and up propagation news from G3YLA and G4BAO The unsettled weather pattern continues to provide a variety of challenging weather types with heavy snow and rain, plus strong winds at times. The nature of such patterns in January is that the timing and track of the lows are critical for the rain and snow outcome. Overall, it's likely to be a cold-system week with occasional brief milder interludes as Atlantic fronts move through in the middle of the coming week. The effect on VHF and UHF propagation is limited with tropo unlikely, but there is a significant chance of rain or snow scatter at times for GHz operators. There have been some slight increases in the Earth's Kp index, which responds to solar activity. However, as we are between the peak periods of autumn and spring for aurora, it's probably not a major player this time. Meteor scatter has been a bit more interesting lately due to the peak of the Quadrantids meteor shower on the 4th of January. The shower has a short, intense peak, but spans the period from the 28th of December to the 12th of January. The next major shower isn't until April, so it's back to random activity from this weekend through to the late April Lyrids. Lastly, a reminder that mid-winter Sporadic-E does happen. The 6th of January saw a nice early evening 6m band opening to the Baltic states, moving round to Ukraine and the Balkans later. Recent Quadrantids meteors may have contributed some long-lived metallic ions, which can be focused into thin Sporadic-E patches. It's always worth checking the Sporadic-E Layer Critical Frequency values plotted on the Propquest graphs for short spikes in the purple trace, which could be a sign of potential interest in Sporadic-E on the 10 and 6m bands. For EME operators, Moon declination is negative again, and we are past perigee, so path losses are increasing, and Moon window length and peak elevation are reducing. 144MHz sky noise remains low but rising to high by Friday the 16th. And that's all from the propagation team this week.

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 18th of December 2025 Last week, we suffered from the double whammy of a reduced solar flux index and an increased Kp index. The solar flux index went down to 119 by Thursday, the 18th, with the sunspots looking pretty spartan when compared with just a week or so ago. Unfortunately, a coronal hole contributed to a fast solar wind with a south-pointing interplanetary magnetic field or Bz. The net result was a Kp index of 5 and a minor G1 geomagnetic storm. Nevertheless, the maximum usable frequencies, or MUFs, over a 3,000km path mostly remained above 28MHz, at least during daylight hours, and there was DX to be worked. As it's Christmas, let's focus on special calls for the season. YR0XMAS in Romania has been worked on the 20m band using CW and will be active until the end of the month. A little further afield is the 12 Days of Christmas event in the US. It runs until Christmas Day with 12 three-letter callsigns in the W2 and K2 series. You only have to work one to get a certificate, so it should be possible for most amateurs. If you are lucky enough to work all 12, plus a bonus station in Puerto Rico, you can get a special ‘Clean Sweep Plus' endorsement. W2S has already been spotted in the UK, and more details are available by Googling ‘12 days of Christmas ham radio'. Next week, we have another large coronal hole to contend with, which NOAA predicts may push the Kp index to 5 between the 22nd and 26th of December. The good news is that the solar flux index may increase over the same period, perhaps up to 180 by the 28th of December. Make the most of the low bands as we hit the winter solstice, with its long periods of darkness. And certainly check 14 to 28MHz during daylight hours. And now the VHF and up propagation news from G3YLA and G4BAO The tail end of the previous week ended on a dramatically mild, wet and windy note, with heavy rain and gales in places. It might be good for the earth, but little else springs to mind other than some chance rain scatter for the GHz folk. The main feature of this Christmas propagation report is that we have a major change becoming established after this weekend. This change takes the form of swapping out the mild Atlantic pattern for a blocked, cold easterly flow with high pressure parked to the north of the British Isles near the Faroe Islands. If this takes place as suggested by some of the models, then a much colder easterly wind will remain with us for much of the Christmas week. The strength of the high means that the flow is only likely to produce shallow cloud, barely enough for an isolated wintry flurry on the east coast of England. Lighter winds over northern Britain, closer to the high, will possibly allow some tropo, but it is not convincing in view of the shallow dry layer below the inversion. It will mean some sharp frosts are possible where skies clear. Long dark winter nights are potentially good for seeing meteors, and it is worth mentioning two showers this time. The first is the Ursids, which peak around the 22nd and 23rd of December. The second shower to be aware of is the Quadrantids, which peaks on the 3rd and 4th of January. This is a much larger shower than the Ursids, so maybe the one to focus on for radio activity. Aurora remains on the list, especially in view of the large coronal hole recently. As ever, keep an eye on the Kp index for high values, but it is even better to note conditions on the LF bands for signs of ‘watery' sounding signals. The Sporadic-E folklore often speaks of isolated mid-winter events, and, in view of the two meteor showers adding fuel and there being some useful jet streams, it is certainly worth mentioning. Using the jet stream over the Pyrenees for paths to Spain early this week is a good place to start. For EME operators, Moon declination is rising again, and path losses are decreasing. We are past apogee for the month, the point where the Moon is farthest from the Earth. 144MHz sky noise is also reducing again after reaching a peak yesterday, the 20th of December. And that's all from the propagation team this week.

Podcast ONE: 12 de diciembre de 2025 Podast ONE: Cierre de año en One Digital: apagones, continuidad digital, dudas reales sobre IA, The Game Awards y la ruta a CES y al Mundial 2026.#PodcastONE #one_digital #onedigital #OneDigital #tecnología #inteligenciaartificial #gaming #CES #TheGameAwards #Mundial2026 Escucha aquí el Podcast ONE: 12 de diciembre de 2025 YouTube Live One Digital cierra 2025 con apagones resiliencia digital IA y gaming rumbo a CES y el Mundial 2026 Panorama general del episodio El episodio del viernes 12 de diciembre de 2025 funciona como cierre de ciclo: repasa lo vivido durante el año y aterriza temas prácticos de vida digital, consumo tecnológico, videojuegos, movilidad rumbo al Mundial 2026 y dudas crecientes sobre el uso real de la inteligencia artificial en empresas. Inicio de programa y cierre de año Una despedida con enfoque tecnológico El programa abre con un tono de despedida de año: “cerrar ventanas” para abrir lo nuevo y reconocer que 2025 fue intenso en tendencias, consumo y cambios en la forma de publicar y operar en la era digital. Semana cargada de temas Se anticipa que la semana estuvo marcada por noticias de inteligencia artificial, temporada de compras (Cyber Monday, El Buen Fin, Black Friday) y un ambiente de fin de año que influye en decisiones de consumo tecnológico. Apagón en São Paulo y fragilidad de la vida digital Treinta y seis horas sin luz Se narra una “patoaventura” en São Paulo: un periodo prolongado sin electricidad obligó a improvisar para trabajar, publicar y mantener comunicación, pasando por no-break, laptop, tableta y teléfono, hasta quedarse sin energía disponible. Cuando se va la luz también se cae el mundo La experiencia se usa para mostrar un punto básico: sin electricidad, la conectividad se vuelve incierta; y sin conectividad, incluso acciones simples (comunicarse o publicar) se complican. Clima extremo y ciudad no preparada Se menciona la presencia de vientos muy intensos y la caída de árboles como detonante del apagón, con una lectura crítica: las ciudades que no han modernizado infraestructura (por ejemplo, cableado expuesto) quedan más vulnerables ante eventos climáticos fuertes. Guía práctica de continuidad en casa No-break y protección de equipos Se explica por qué un no-break no solo sirve para “seguir trabajando un rato”, sino para proteger equipos cuando el voltaje regresa de forma irregular. Powerbanks con lógica de capacidad Se propone comprar baterías portátiles con base en la capacidad del celular: si un teléfono tiene alrededor de 5,000 mAh, una batería de 10,000 mAh puede dar margen para una o más recargas según pérdidas y uso. Preparación doméstica para contingencias El episodio sugiere adoptar hábitos de preparación: tener energía de respaldo mínima, contemplar necesidades de varias personas en casa y evitar depender de un solo dispositivo. Publicación móvil y herramientas: lo que sí funciona y lo que estorba El celular como herramienta editorial Se subraya que hoy el teléfono puede resolver tareas periodísticas y de publicación, pero se reconocen límites cuando el flujo requiere edición, inserción de elementos y trabajo fino en WordPress. Modo escritorio en Android y fricciones con tableta Se comenta el uso de funciones tipo “modo escritorio” en Android para operar como si fuera una computadora y la diferencia de experiencia al trabajar en un iPad, donde cambian atajos y hábitos. Almacenamiento saturado: la crisis silenciosa de la productividad Quedarse sin espacio en Google y perder control Se relata el problema de saturación de almacenamiento y su impacto en correo, edición de video y ritmo de trabajo: cuando el espacio se termina, incluso recibir mensajes puede volverse incierto. Video y peso real de los archivos Se habla de la tensión entre grabar en 4K y mantener un flujo sostenible: editar y respaldar consume espacio rápido, y la falta de almacenamiento obliga a bajar calidad o depurar material. Discos duros y salto de costos Se comenta la búsqueda de discos externos de alta capacidad y cómo los precios suben cuando se pasa de capacidades comunes a opciones mayores. Alternativas de respaldo y orden digital NAS como nube personal Se presenta la idea de un NAS como alternativa para quienes quieren una “nube propia”, con almacenamiento local escalable y control sobre el respaldo. Servicios gratuitos con límites Se mencionan opciones de nube gratuita y su costo real: anuncios, limitaciones de descarga o calidad y velocidades variables. Depuración de Drive correo y mensajería Se recomienda revisar archivos compartidos vinculados a cuentas, borrar material repetido y no subestimar el peso de historiales de mensajería, especialmente cuando se acumulan imágenes y videos. Telegram como “bodega” informal Se menciona un uso común: enviarse archivos a uno mismo en Telegram como solución práctica para mover o resguardar material cuando urge liberar espacio. Puebla: gastronomía turismo y producción de contenido Visita al Hotel Cartesiano Se cuenta un viaje a Puebla para conocer restaurantes del Hotel Cartesiano y probar menú de temporada, con enfoque en experiencia gastronómica y atención del equipo en Comedor 360 y el restaurante Custodia del chef Alan Sánchez. Producción visual y fotografía nocturna Se describe la toma de fotografías en el centro, la búsqueda de escenas “instagrameables”, y el uso de aplicaciones para ajustar sombras o profundidad en imágenes. Sonoterapia y experiencia auditiva Se narra una sesión con cuencos y la percepción del sonido como algo envolvente, conectándolo con referencias de audio inmersivo y pruebas de audífonos. Efecto de audio tipo “Torbellino”. Mundial 2026: movilidad en Ciudad de México y efectos en turismo Nuevas rutas y transporte dedicado Se menciona un circuito de trolebús con carril exclusivo para conectar zonas de alta concentración (como Chapultepec) con el Estadio Azteca, con el objetivo de reducir tráfico y facilitar traslados masivos. Tren ligero y alternativas Se comenta la ampliación del tren ligero en el corredor Tasqueña–Estadio Azteca y el crecimiento de opciones como teleféricos urbanos en distintos puntos, como parte de un ajuste gradual de movilidad. Seguridad vial y desorden de micromovilidad Se critica el caos en calles y ciclovías: bicicletas y motos invadiendo espacios, conductas irresponsables y riesgos de infraestructura (como coladeras peligrosas) que pueden causar accidentes. Guía de compra: televisiones para el mundial Por qué se disparan las ventas Se plantea que un Mundial empuja el consumo de televisiones y que el mercado empuja tamaños cada vez mayores con precios más accesibles que años atrás. Antes de comprar: espacio y montaje Se recomienda definir dónde irá la televisión, cómo se montará, cómo se ocultarán cables y si el peso y el transporte son viables. Conexiones mínimas para uso real Se sugiere revisar puertos HDMI y USB para conectar consola, receptor o dispositivos adicionales, incluyendo equipos antiguos si el hogar todavía los usa. Android TV y asistentes Se describe el valor de televisiones con Android TV para instalar aplicaciones y reproducir contenido dentro de la misma red, además de asistentes que permiten acciones simples por voz. Dispositivos externos Se menciona que algunas personas prefieren usar equipos externos (como Roku o Apple TV) aun teniendo televisión inteligente, para mantener control y consistencia de aplicaciones. The Game Awards 2025: ganadores anuncios y lectura del evento Desvelo y presión de publicación Se relata la cobertura del evento en horarios complicados, y el reto de publicar rápido sin sacrificar verificación. El gran ganador de la noche En la conversación se afirma que “Clair Obscur: Expedition 33” fue el juego más premiado, llevándose juego del año y varias categorías relevantes, y se comenta el tono “espectáculo” del evento. Categorías y señales de industria Se mencionan categorías como adaptación, juegos con impacto social, accesibilidad y deportes electrónicos, como prueba de que el evento ya es una vitrina industrial, no solo una premiación. Anuncios y marketing Se comentan anuncios como Lego Batman y la conversación alrededor de juegos muy anticipados, mostrando cómo el evento se usa para lanzar avances y reforzar expectativas. Consolas PC y propiedad del juego Qué comprar: consola o computadora Se discute el dilema de regalos: una consola híbrida como Switch 2 puede ser atractiva por portabilidad, pero una computadora puede dar acceso más amplio a catálogo, precios y flexibilidad. Exclusivos y cruce entre plataformas Se plantea que la exclusividad se ha debilitado y que cada vez más títulos terminan llegando a múltiples plataformas, empujando el juego cruzado. Licencias y el “juego rentado” Se critica que en algunos ecosistemas la compra funciona más como una licencia condicionada que como una propiedad permanente, lo que abre el debate sobre acceso a futuro. Inteligencia artificial: avance real y frustración cotidiana Una semana de pelea contra la herramienta Se describe una experiencia de trabajo donde la IA entrega respuestas incompletas, se distrae del encargo o “alucina”, obligando a corregir y repetir instrucciones en vez de ahorrar tiempo. Adopción en empresas y resultados dudosos Se menciona que muchas organizaciones pagan por herramientas de IA sin lograr uso constante en su plantilla y sin poder demostrar beneficios claros en resultados. Riesgo de burbuja y exageración comercial Se comentan lecturas y cifras circulando sobre inversiones y deuda alrededor de infraestructura de IA, con cautela explícita: no se afirma como hecho cerrado, se plantea como tendencia que requiere confirmación en fuentes confiables. Privacidad visas y control de datos Redes sociales y vida digital como requisito Se cuestiona la posibilidad de que trámites migratorios exijan revisar redes sociales y rastros digitales, y se discute el choque con la idea de privacidad y derecho al olvido. Bancos y trazabilidad Se comenta que bancos y gobiernos pueden reconstruir hábitos de vida a partir de movimientos financieros, y se relatan procesos de validación bancaria que piden datos detallados para mantener cuentas activas. Reacciones internacionales pendientes Se señala que una parte clave es cómo reaccionan gobiernos y reguladores, especialmente fuera de Estados Unidos, ante medidas percibidas como intrusivas. Consumo conectividad y notas de industria Buen Fin 2025 y peso de publicidad Se mencionan cifras de comportamiento de compra y el papel de anuncios y redes sociales en decisiones, además de comparaciones entre compras en línea y en tienda. Telmex y Hyper Wi-Fi 7 de Infinitum Se menciona el anuncio de Hyper Wi‑Fi 7 como promesa de mayor capacidad, menor latencia y soporte para muchos dispositivos, con banda de 6 GHz, a la espera de conocer precios y despliegue real. Supercómputo y ciencia aplicada Se comenta una nota sobre una supercomputadora de HPE y usos científicos como simulación, modelos climáticos y análisis de proteínas, como parte del bloque informativo de la semana. Rumbo a CES y forma de cubrir tecnología Adelantos con embargo Se anticipa cobertura desde CES y se menciona que hay productos vistos previamente de marcas como Motorola y Lenovo, pero que algunos detalles no pueden publicarse por embargo. Velocidad contra calidad Se plantea el dilema editorial: publicar rápido frente a producir piezas bien armadas, verificadas y editadas, evitando transmisiones improvisadas con poca información.

GB2RS News Sunday, the 14th of December 2025 The news headlines: Dr Bob Whelan, G3PJT, is now a Silent Key Two exciting opportunities to make an impact with the RSGB Free RSGB club affiliation for schools, universities and uniformed groups! It is with great sadness that we share the news that Dr Bob Whelan, G3PJT, became a Silent Key on the 4th of December. Bob's contribution to amateur radio was extensive. First licensed in 1961, his main interest was in HF and LF CW operation. In this, he soon became a strong supporter of the Commonwealth Contest, operating from a number of DX locations for the contest over many years. He wrote the book ‘Reflections in a Rosebowl', which covers the history of the Commonwealth Contest, and he put much effort into building an online Commonwealth Contest community. Bob also played a very significant role in the RSGB, the IARU and the First Class Operators Club. For the RSGB, he started as a volunteer member of the RSGB HF Committee and later was President from 2002 to 2003 and again from 2013 to 2014. Our thoughts are with his family and friends. You will be able to read a full tribute to Bob in the February 2026 edition of RadCom. Are you an experienced operations leader who is passionate about delivering exceptional membership services and driving commercial growth? Or are you an advertising agent looking for a new opportunity where you can demonstrate your strong sales capabilities, excellent communication skills, and your ability to build and maintain long-term client relationships? The RSGB is seeking a full-time, highly motivated Operations Manager to be part of its senior leadership team, based at the RSGB HQ in Bedford. This is a key role, responsible for ensuring our members receive outstanding service, and the successful candidate will need to be commercially astute, organised, people-focused, and excited by the opportunity to make a meaningful impact. The Society is also looking for a new contractor or agency to work with, to support the development of RSGB advertising and contribute to the growth of its publications and digital platforms. If you are professional, proactive and excited by either of these opportunities, go to the RSGB website at rsgb.org/careers to find out more. The application deadline for both is the 4th of January 2026. Did you know that amateur radio clubs in schools, universities and uniformed groups can affiliate with the RSGB for free? Your club will benefit from a copy of RadCom in the post each month, as well as access to the RSGB app, where you can read RadCom, RadCom Basics and RadCom Plus. You'll also get special book discounts, promotion of your club's activities, access to RSGB-affiliated club contests, and use of the QSL Bureau. Visit rsgb.org/affiliation and follow the links. How about giving back to the amateur radio community in 2026 by becoming an RSGB Board Director? The RSGB has two Elected Board Director vacancies and wants to ensure that the voices around the table understand and reflect the community it serves. You'll need leadership experience and be keen to play an active part in helping to support the Society's strategic priorities. The Society is encouraging candidates from a diverse range of backgrounds to stand for election. Go to rsgb.org/elections to find out more. The closing date is the 31st of January 2026, so act now. The RSGB Contest Club is excited to report that the third World Wide Award event will be taking place in January 2026. Award hunters can engage in a very enjoyable competition across all HF bands and modes, with many special international calls to work. The RSGB will be activating seven callsigns, all with the suffix ‘WWA'. RSGB members who hold a Full licence may activate the callsign for their country. To find out more, go to rsgb.org/contest-club YOTA Month continues this weekend with special call sign GB25YOTA. Listen out for operators from the RSGB National Radio Centre and the 2nd Marlborough Scouts. Students from Buckie High School, Wick High School and Simon Langton Boys School Radio Club will be active during the week, as well as The University of Sheffield Amateur Radio Club. Next weekend Cambridge University Wireless Society, along with some young visitors, will be active. Listen out and encourage these young operators. View the operating times, bands and modes for each group at rsgb.org/yota-month RSGB HQ will close on Wednesday, the 24th of December 2025, at 2 pm and will open again at 8.30 am on Monday, the 5th of January 2026. In the meantime, if you need information about amateur radio, exams or RadCom, you'll find lots of details on the website at rsgb.org.

Look for activity throughout December on the 40 to 10m bands, as well as on the 6m, 2m and 70cm bands using CW, FT8, FM, RTTY and SSB. Jose, HP2AT, is active as H82AT until the 31st of December to celebrate his 35th anniversary in amateur radio. Recently, the station has been spotted using FT8 on the HF bands. All QSOs will be uploaded to QRZ.com, Club Log, eQSL and Logbook of the World. In celebration of the GB2RS News service's 70th anniversary, Sean G7NJX will be active with the GB70RS callsign from the 15th to the 21st of December. Sean will be working on the 80, 40 and 20m bands using CW, FT4, FT8, PSK31, RTTY and SSB. There is a schedule of bands, modes, and operating times for the week on Sean's QRZ.com page. He will also do his best to spot his activity on the DX cluster. Now the DX news Roland, F8EN, is active as TR8CR from Gabon until the end of December. He is operating using CW only. QSL via F6AJA. Now the contest news The ARRL 10m Contest started at 0000UTC yesterday, the 13th, and ends at 2359UTC today, the 14th of December. Using CW and phone on the 10m band, the exchange is signal report and serial number. American and Canadian stations also send their state or province code. Tomorrow, Monday the 15th of December, the RSGB FT4 Contest runs from 2000 to 2200UTC. Using FT4 on the 80 to 10m bands, where contests are permitted, the exchange is your report. On Tuesday, the 16th of December, the RSGB 1.3GHz UK Activity Contest runs from 2000 to 2230 UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator. On Thursday, the 18th of December, the RSGB 70MHz UK Activity Contest runs from 2000 to 2230 UTC. 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 11th of December We had a bit of everything last week, including increased Kp indices, a high solar flux, an X-class solar flare and coronal mass ejections. The solar flux index hit a maximum of 220 on Thursday, the 4th of December. This brought good HF conditions until Sunday, the 7th. The index declined to 169 on Thursday, the 11th, which was still more than enough to excite the ionosphere. We had an X-class solar flare at 0501UTC on Monday, the 8th of December. This originated from large active region 4298, which has now rotated out of view. We also had more than ten M-class solar flares over the past week, showing that the prediction of disturbed conditions on the downward part of the solar cycle still holds true. The Kp index hit 6.33 on Wednesday, the 10th, which disrupted maximum usable frequencies, or MUFs. The net result was that digisonde traces were missing at times, with the MUF over 3,000km being in single figures on Thursday, the 11th of December. To cap it all, we now have a very large Earth-facing coronal hole that threatens HF propagation today, the 14th of December. There has been DX around, but mostly on the lower bands. CDXC's Slack group reports that KP2B on St Croix was worked on the 80m band using FT8 on the morning of Thursday, the 11th of December. TO9W on St Martin was logged on the 40 and 30m bands using CW on Tuesday, the 9th of December. TT1GD in Chad also appeared on the 40m and 20m bands using CW on Monday, the 8th of December. Next week, NOAA predicts the solar flux index will be in the 130 to 140 range. However, as was mentioned earlier, geomagnetic conditions may be disturbed today, the 14th, due to a fast solar wind stream from a coronal hole. Conditions might calm down from the 15th to the 20th, before the Kp index hits 5 around the 21st to the 26th of December. In summary, get your HF DXing in during next week, before auroral conditions take their toll over the Christmas period. And now the VHF and up propagation news from G3YLA and G4BAO The present period of unsettled weather will remain the driving force for weather conditions for most of the country for the period up to Christmas. This will mean that there are likely to be some very windy spells with extensive rain and squally showers. It offers scope for rain scatter operators on the GHz bands, but scarcely any hint of good tropo conditions. One item of interest is the meteor scatter prospects from the Geminids, which peak today, the 14th of December. It is one of the busiest showers of the calendar with a peak hourly rate of 120, so it should provide plenty of opportunities and is worth exploring during the week before and following the peak. The solar conditions have again remained interesting enough with a red alert on the evening of Wednesday, the 10th of December, and there is always the potential for the Kp index to produce signs of auroral radio activity once it goes above 5. Finally, a reminder that this winter period, from mid-December to mid-January, can produce some surprisingly effective Sporadic-E. It's possibly easiest to see by checking the propquest.co.uk graphs to see if the foEs trace is showing any sharp spikes. The 10 and 6m bands are probably the more likely bands to show signs of activity in these winter events, but it's certainly worth checking if the graphs show any promising signs. For EME operators, Moon declination went negative on Friday the 12th of December, meaning shortening Moon windows and decreasing peak elevation. We are past perigee for the month, so path losses are increasing. 144MHz sky noise starts low but increases to high by Friday, the 19th of December, when the Sun and Moon are close in the sky. And that's all from the propagation team this week.

A handful of places still let your nervous system breathe, and Green Bank, West Virginia, is one of them. We sit down with returning guest Andrew McAfee—author, inventor, teacher and licensed electrician—to unpack why the town's famed radio quiet sanctuary is suddenly vulnerable and what it will take to keep it intact. A recent policy shift around 2.4 GHz opens the door to Wi‑Fi meshes, smart meters and new towers that could erase the very conditions that make recovery possible for so many.There's a practical path forward. Children's Health Defense is engaged to push a targeted update to West Virginia state law so protections extend to people, not only the telescope. The strategy is concrete: fund the legal brief, sustain lobbying, and lock in a framework that prevents 2.4 GHz from seeding the very infrastructure Green Bank has long avoided. Andrew also shares how Safe Home helps electrically sensitive residents navigate housing and power-grid issues so they can actually live well in this unique low-EMF area.Your help can make the difference, please consider donating now to this important initiative: https://childrenshealthdefense.org/support/protect-the-national-radio-quiet-zone/Avoid fees by mailing a check to:Children's Health Defense852 Franklin Ave., Suite 511Franklin Lakes, NJ 07417Include a note that the donation is specifically for the "Protect the NRQZ"These special prices are good only through the end of October 2025.

C'est un chantier d'une ampleur rare : l'ARCEP, le gendarme des télécoms, vient de lancer une grande consultation nationale pour réorganiser le spectre radioélectrique français. Objectif : préparer l'arrivée de la 6G et redéfinir la répartition des fréquences entre Orange, SFR, Bouygues Telecom et Free pour la décennie 2030-2040. Un travail d'ingénierie stratégique qui conditionnera notre futur numérique.Chaque opérateur dispose de licences d'exploitation sur des bandes de fréquences, un peu comme des concessions autoroutières. Les bandes dites basses couvrent les zones rurales, les hautes offrent des débits records mais une portée limitée, et les moyennes servent d'équilibre entre les deux. Problème : toutes ces licences expirent entre 2030 et 2035, au moment même où la 6G sortira des laboratoires.Dans un document de 39 pages, l'ARCEP interroge les opérateurs : à quels usages répondra la 6G ? À quel horizon ? Quels besoins en couverture, en puissance ou en mutualisation ? Le régulateur évoque une transition progressive, depuis la 5G « Standalone » actuelle vers une 5G « Advanced », avant le grand saut vers la 6G, plus intelligente et connectée aux satellites. L'un des grands enjeux, c'est la bande des 6 GHz, identifiée fin 2023 comme le futur axe autoroutier du trafic mobile. Un territoire convoité aussi par le Wi-Fi, et qui fait déjà l'objet d'âpres négociations à Bruxelles. L'ARCEP veut défendre la position française avant une décision européenne prévue en 2027.La facture, elle, s'annonce salée. En 2024, les investissements des opérateurs ont déjà atteint 12,4 milliards d'euros. Faut-il privilégier de nouvelles enchères ou des obligations de couverture ? La question reste ouverte. Dernier sujet clé : la connectivité satellite directe, qui permettrait de se connecter sans antenne terrestre. L'ARCEP veut savoir si les opérateurs français sont prêts à partager leurs fréquences avec ces futurs partenaires spatiaux. Les réponses, attendues pour mi-décembre, traceront la carte du mobile français à l'horizon 2040. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

Alors que le Wi-Fi 7 commence tout juste à s'installer dans nos foyers, l'industrie prépare déjà la suite. Le constructeur TP-Link a annoncé avoir réalisé la première transmission de données en Wi-Fi 8, aussi connu sous le nom technique 802.11bn. Une démonstration effectuée à l'aide d'un prototype développé avec un partenaire resté anonyme, qui marque une étape clé vers le futur standard du sans-fil, attendu d'ici la fin de la décennie.Mais attention : le Wi-Fi 8 ne cherche pas à battre des records de vitesse. Son véritable objectif, c'est la fiabilité. Selon Qualcomm, l'un des acteurs majeurs du projet, ce nouveau standard représente « un pivot fondamental » : il s'agit moins d'augmenter le débit que d'assurer une connexion stable dans des environnements complexes et saturés.Le Wi-Fi 8 fonctionnera sur les mêmes bandes que son prédécesseur — 2,4, 5 et 6 GHz — pour un débit théorique maximal compris entre 46 et 48 Gbit/s. Mais les vraies innovations se cachent ailleurs :-la technologie Enhanced Long Range (ELR) pour améliorer la portée,-Distributed Resource Units (DRU) pour mieux répartir les canaux entre appareils,-et Unequal Modulation (UEQM), capable d'adapter le signal à chaque terminal connecté.Selon Qualcomm, ces avancées permettront de réduire la latence et les pertes de paquets d'environ 25 %, un gain crucial pour le jeu vidéo en ligne, la réalité augmentée, ou encore les applications industrielles. Pour TP-Link, cette première démonstration confirme la stabilité du signal et la fiabilité du « beacon », l'identifiant propre au Wi-Fi 8. Le projet s'inscrit dans l'initiative Ultra High Reliability (UHR) de l'IEEE, qui vise à maintenir une connexion fluide même dans les zones perturbées — stades, usines, campus ou transports. Les premières spécifications sont attendues en 2027, pour une certification officielle mi-2028. Les premiers routeurs suivront sans doute peu après. Hébergé par Acast.

Bald Yak 13, Monitoring the Sun .. small steps

Foundations of Amateur Radio The other day I received an email from Frank K4FMH asking me about an idea I'd worked on some time ago, namely the notion that I might monitor solar flux at home using a software defined radio. At the time I was attempting to get some software running on my PlutoSDR and got nowhere fast. Before I continue, a PlutoSDR, or more formally an ADALM Pluto Active Learning Module by Analog Devices, is both a computer and a software defined radio receiver and transmitter in a cute little blue box. I've talked about this device before. It's an open design, which means that both the software and hardware are documented and available straight from the manufacturer. Out of the box it covers 325 MHz to 3.8 GHz. You can connect to a PlutoSDR using USB or via the network, wireless or Ethernet, though I will mention that neither of those last two is currently working for me, but more on that later. Encouraged by Frank's email, I set out to explore further and came across a 2019 European GNU Radio days workshop, which discussed some of the tools that are available for the PlutoSDR, accompanied by two PDF documents walking you through the experience. One comment around why the PlutoSDR uses networking as one of the connectivity options spoke to me. From a usability perspective, networking makes it easier to access the PlutoSDR from a virtual machine, since most of the time that already has network connectivity, whereas USB often requires drivers. As you might recall, network connectivity is one of the many things that I'm trying to achieve with a project that I'm calling Bald Yak, since by the time we're done, there's not going to be much hair left from all the Yak Shaving. The Bald Yak project aims to create a modular, bidirectional and distributed signal processing and control system that leverages GNU Radio. As a result, I set about trying to actually walk myself through those PDF tutorials .. and got stuck on the first sentence on the first page, which helpfully states: "The necessary prerequisites have been installed on the local lab machine." It went on to supply a link to a page with instructions on how to acquire those very same prerequisites. Two days later, after much trial and error, I can now report that I too have these installed and because I cannot help myself, I made it into a Docker container and published this on my VK6FLAB GitHub page. To put it mildly, there's a few moving parts and plenty of gotchas. As an aside, if you think that installing Docker is harder than installing these tools, I have some news for you .. trust me .. by a long shot .. it's not. Right now I'm working on writing the documentation that accompanies this project such that you can actually use it without needing to bang your head against the desk in frustration. Mind you, the documentation part of this is non-trivial. For reasons I don't yet understand, my Pluto does not want to talk to the network directly over either WiFi or Ethernet, and connecting over USB through a virtual machine inside a Docker container is giving me headaches, so right now I'm connected across the network to a Raspberry Pi that's physically connected to the Pluto. As a result, I can now use the tools inside my Docker container, connected to the Pluto through the Pi and if you're curious, 'iiod' is the tool to make that happen .. more documentation. At this point you might well ask, why bother? This is a fair question. Let me see if I can give you an answer that will satisfy. Monitoring solar flux typically occurs at 2.8 GHz, which is outside the range of RTL-SDR dongles which top out at about 1.7 GHz. For the PlutoSDR however, it's almost perfectly within the standard frequency range. One of the tools that is introduced by the talk is an application called 'iio-scope', which as the name suggests, is an oscilloscope for 'iio' or Industrial I/O devices, of which the PlutoSDR is one. As an aside, the accelerometer in your laptop, the battery voltage, the CPU temperatures, fans, and plenty of others, are all 'iio' devices that you can look at with various tools. So, once I've finished the tutorials, I suspect that I will understand a little better how some of the various parts of the PlutoSDR hang together, and I can set it up to monitor 2.8 GHz. Of course, that's only step one, the next step is to make a Raspberry Pi record the power levels over time, better still, record it on the PlutoSDR itself, and see if we can actually notice any change .. without requiring anything fancy like a special antenna, some massive filters, a special mount and all the other fun and games that no doubt will reveal themselves in good time. It also means that, if I got this right, I have the beginnings of the bits needed to get the PlutoSDR to talk to GNU Radio. Why? Because I can, and because Frank asked, also Yak Shaving.

EYE on NPI - Qualcomm &amp; Arduino UNO Q Microcontroller Board

Adafruit Industries

This week's EYE ON NPI is as mysterious and powerful as the extra-dimensional being from Star Trek (https://en.wikipedia.org/wiki/Q_(Star_Trek)) - it's the new Arduino UNO Q (https://www.digikey.com/en/product-highlight/a/arduino/uno-q-microcontroller-board) microcontroller board, released as part of the Qualcomm/Arduino acquisition announcement (https://www.qualcomm.com/news/releases/2025/10/qualcomm-to-acquire-arduino-accelerating-developers--access-to-i). This Uno-shaped board is packed with both an STM32 microcontroller and a Qualcomm Dragonwing microprocessor so you get the best-of-both-worlds: 3.3V/5V logic compatibility with timers and ADCs, plus a full Debian install and AI support for running local vision models. We last checked in on Arduino we were reviewing their new announcements based on a partnership with Renesas: the Arduino Nano R4 SoC (https://www.youtube.com/watch?v=QLAI41ZfCfw) which is a miniaturized version of the UNO R4 (https://www.youtube.com/watch?v=uw0EU8urz5M). These boards feature an Arm microcontroller, with lots of fun on-board accessories like an LED grid, Qwiic connector, and WiFi/Bluetooth module. These boards represented a bump in capabilities over the classic UNO R3 (https://www.digikey.com/en/products/detail/arduino/A000073/3476357) but are still under-powered compared to the 'Portenta' line (https://www.digikey.com/en/products/detail/arduino/ABX00045/15294134). So, when we see the Arduino UNO Q (https://www.digikey.com/short/qc9d09fm) is a merging of three separate 'strands' of Arduino development history. One, it's shaped and has hardware-compatibility with the classic UNO which has been their mainstay for decades. Two, it has the powerful microcontroller type that the Pro line features. And three, it revives some of the Linux-based boards that Arduino had previously released like the Yun (https://www.digikey.com/en/products/detail/arduino/A000008/4486331), Tian (https://docs.arduino.cc/retired/boards/arduino-tian/) and Tre (https://docs.arduino.cc/retired/boards/arduino-tre). What sets the Q apart is that this time instead of being just a chip-supplier partnership, Arduino has been acquired as a subsidiary of Qualcomm (https://www.qualcomm.com/news/releases/2025/10/qualcomm-to-acquire-arduino-accelerating-developers--access-to-i) which means that there's going to be first-class engineering support for the onboard Dragonwing processor. Speaking of, let's take a look at the hardware included in the new Q! There's two chipsets on each board: the big processor is a Qualcomm Dragonwing™ QRB2210 (https://www.digikey.com/en/products/detail/qualcomm/QRB-2210-0-NSP752-TR-00-0/27904331) - 64-bit System-on-Chip with 4 × Arm Cortex-A53 running at 2.0 GHz and Adreno 702 GPU running at 845 MHz for 3D graphics. This chip runs mainline Debian OS with upstream support so you can configure a kernel and distribution image without needing patches. Arduino and Qualcomm distribute their own ready to go image too (https://docs.arduino.cc/tutorials/uno-q/update-image/). This chip has modern A/V support with both CSI camera and DSI MIPI display capability to match. Those high speed connects are available on the dual 60-pin bottom connects - while there isn't a sub-connect board right now, it's likely that Arduino will develop one soon. Meanwhile, you can use their documentation (https://docs.arduino.cc/hardware/uno-q/) such as STEP and Gerber files if you want to start adding a direct-plug integration into your hardware now. The second chipset is a STM32U585 Arm Cortex-M33 with 2 MB Flash, 786 kB SRAM and running at 160 MHz - it runs the Arduino Core via Zephyr OS and from the block diagram, looks like it communicates with the main core via UART and SPI. The STM is what handles GPIO, PWM, ADC, DAC, timers, etc since it is 3.3V logic and has some 5V logic-level compatibility. The main headers on the Arduino - and some of the bottom extra headers - expose the STM logic so you can connect standard sensors, OLEDs, relays etc. While there are some GPIO from the Dragonwing also available, they're 1.8V logic and are already allocated in the Linux Device tree. The Arduino UNO Q (https://www.digikey.com/short/qc9d09fm) is available for pre-order right now from DigiKey for a door-busting $44! We've already put in our order, and we'll do a project to check it out as soon as it arrives. After you get your pre-order in, check out some of the projects that have already been published to get a sense of the Q's capabilities like this MAME emulation arcade cabinet (https://projecthub.arduino.cc/jcarolinares/arduino-uno-q-arcade-cabinet-machine-39dd38) or face-recognition car (https://www.youtube.com/watch?v=EGDxAXpH_Ag). You can start dreaming of what you'll be able to do with a full computer + microcontroller board that fits where your old UNO R3 would fit, while you wait for the shipping notification.

professorjrod@gmail.comWhat if your “all-in-one” router is doing too much—and your Wi‑Fi “speed” isn't the real bottleneck? We pull back the rack door and trace the digital bloodstream from SOHO setups to enterprise backbones, translating jargon into choices you can actually make. Starting with LANs, WANs, WLANs, and SANs, we map how scope changes design, cost, and risk, then contrast the convenience of a home gateway with the clarity of dedicated roles—routers, switches, firewalls, and load balancers—working like a well-tuned orchestra.We get tactile with the gear: NICs and their 48‑bit MAC addresses, patch panels that keep closets sane, and switches that forward with CAM tables instead of shouting like hubs. You'll hear where managed switches earn their IP address (management only), why VLANs and QoS matter, and how Power over Ethernet (802.3af/at/bt) cuts clutter while powering VoIP phones, APs, and cameras with fewer failure points. From copper categories (Cat6/6A) and clean terminations to testers, toners, and taps, we highlight the unglamorous steps that prevent the worst outages.Then we cut the cord. We chart Wi‑Fi's arc—802.11a/b/g to n, ac, and 6/6E—clarifying bands, channels, MIMO, and OFDMA so your network stops fighting itself. We talk survey tools, interference traps, and when to steer clients to the right lanes. Fiber gets its due as the distance champion—single‑mode for long haul, multi‑mode for shorter runs—with connector gotchas that can burn hours. And because connectivity is more than Wi‑Fi, we touch Bluetooth peripherals, RFID access, NFC payments, and long‑range links that fill gaps where cables can't go.To anchor the learning, we run quick cert‑style questions—switches and MACs, routers and IPs, PoE's true advantage, and Wi‑Fi 5's 5 GHz focus—so you can test yourself in real time. Whether you're building a home lab, prepping for CompTIA, or planning an upgrade at work, you'll leave with practical mental models and checklists you can use today.

Though not widely discussed, EMFs have been classified by the World Health Organization as a Class 2B possible carcinogen and are linked in over 2,000 studies to issues like:DNA damageNeurological disordersSleep disruptionCardiovascular diseaseFertility problemsArthur's background in biology and engineering, plus personal experiences with illness in his family, led him to explore the health risks of EMF exposure and design protective clothing through HAVN.As technology evolves (especially with 5G and 6G), EMF exposure is increasing. Newer tech requires more antennas and emits stronger frequencies, especially in urban areas and smart homes filled with connected devices.Even wearables like fitness trackers (e.g., WHOOP) and cell phones—due to proximity—may be worse offenders than Wi-Fi routers. EMFs are likened to pollution: invisible, everywhere, and cumulative in their effects over time.Arthur emphasizes reducing exposure, especially during sleep (1/3 of your life!), as a powerful first step. His top free or low-cost tips:Put your phone on airplane mode or keep it out of the bedroom at night.Turn off your Wi-Fi router overnight (via timer plug if necessary).Avoid sleeping with wearables like WHOOP or smartwatches.Keep devices off your body when not in use.Use EMF meters (offered by HAVN) to detect high-emission areas in your home.Arthur developed HAVN Clothing (spelled HAVN, removing “EMF” from “haven”) to shield essential organs from EMF without compromising modern life. Their proprietary WaveStopper fabric blocks 99.7% of EMFs (400 MHz–40 GHz) using silver fiber mesh.Available products include:PajamasUnderwearHats and beaniesGaiters for thyroidBlanketsHoodies for travelThese are particularly helpful for people living in apartments or dense urban environments where community EMF exposure is high. For beginners, Arthur recommends starting with headwear, underwear, and sleepwear to protect the most vulnerable organs during sleep.If you're interested in online personal training or being a guest on my podcast, "Over 40 Fitness Hacks," you can reach me at brad@over40fitnesshacks.com or visit my website at:www.Over40FitnessHacks.comAdditionally, check out my Yelp reviews for my local business, Evolve Gym in Huntington Beach, at https://bit.ly/3GCKRzV

How small is small?

Foundations of Amateur Radio I've owned a Yaesu FT-857d radio since becoming an amateur and at the time I was absolutely blown away by how much radio fits inside the box. It's smaller than most of the commercial radios I'd seen when I bought it. I came across a video by Michael KB9VBR, the other day showcasing a wooden cigar box with a complete, well, almost complete POTA, or Parks On The Air, activation kit. I say almost, since Dave KZ9V, the owner of the kit, points out that the box doesn't contain an antenna. It made me wonder how small is small? According to RigPix, the lightest transmitter on an amateur band, in this case, the 5 GHz or 5cm band, is an Amateur TV transmitter. Weighing in at 3.9 grams. The Eachine TX-06 is capable of FM with about 18 MHz of bandwidth with an audio sub-carrier. Of course, that's not a transceiver, but I thought it worth mentioning in case you needed an excuse for something tiny in your shack, besides, as far as I can tell, there's never too much Amateur TV in the world. I've built a crystal radio on a breadboard which is tiny, but it doesn't transmit, so to set the stage, I think we need to limit ourselves to transceivers, that is, a device capable of both transmitting and receiving, on amateur bands. Before continuing I'd like to express my thanks to Janne SM0OFV, for the rigpix.com database that he's been maintaining, in notepad, since 2000. Without the invaluable information documented for the currently 7,512 radios, I'd be spending an awful lot of time hunting for information. Moving on, the FaradayRF board is a transceiver, capable of using 900 MHz or the 33cm band. It comes in at 30 grams, but without a computer it's a circuit board with potential. The PicoAPRS by Taner DB1NTO, is a 2m transceiver specifically for APRS, weighs in at 52 grams and similar in look and a third of the weight of an Ericsson T18 mobile phone. Speaking of mobile phones, the PicoAPRS does WiFi and Bluetooth, can pair with your phone and act as an AX.25 modem. I'll confess, I'm drooling. Moving right along, for 70cm there's a Rubicson Walk 'n' talk, weighs in at 65 grams. Mind you, the RigPix database puts this under the "License-free / PMR446" section which comes with a sage warning, check your local laws before transmitting. There's a few Alinco DJ-C models for different markets that operate on 2m or 70cm, weighing in at 75 grams. The ADALM Pluto weighs 114 grams, but you'll need a USB power supply of some sort to make it do anything. It can operate between 70 MHz and 6 GHz, but the user interface is limited to a single button and LED, so if you want to interact with it, you'll need some external technology. Moving on to HF transceivers, weighing in at 199 grams, without the bag, but all the options, is the Elecraft KH1. Transmits on 40m, 30m, 20m, 17m and 15m and receives between 6 and 22 MHz. It's CW only, but you can receive SSB. If CW isn't your thing, RTTY and PSK can be used on the 40m band with a Silent System Handy PSK 40. Presumably the Handy PSK 20 runs on 20m. Both weigh in at 250 grams. The Zettl P-20xx SSB does SSB, AM, FM and CW, transmits on 10m, 11m, 12m and 15m as well as the MARS frequencies and receives between 14 and 30 MHz, weighs 300 grams. Even comes with CTCSS. Another Elecraft model, the KX2 weighs in at 370 grams, does 80m to 10m and the WARC bands, does SSB, CW and data. Mind you, you'll also need to add the weight for the microphone and paddles, and factor in a computer if you want to do more than PSK and RTTY. The Expert Electronics SunSDR2 QRP does 160m to 10m, the WARC bands and 6m. Weighs in at 500 grams, has a network port and two independent receivers. Operates at 5 Watts. There's no user interface, unless you count the reset and power buttons, so I'm not sure if it can operate on any mode with just a microphone, but given the "Depending on software" disclaimers throughout, I'm going to guess you'll need to bring a computer to make it sing. The Risen RS-918SSB does all HF amateur bands between 160m and 10m, has a user interface and display, even a big tuning knob, has built-in FreeDV and does FM, SSB and CW. I'd hazard a guess that this is the lightest self-contained transceiver that you can take out on a POTA mission to a park. Weighs 623 grams and comes with an internal battery. The Elecraft KX3 also does 160m to 10m, and 6m, with a 2m option. Weighs in at 680 grams, but that doesn't include any options. And finally, we pass 1 kilogram and hit 1,100 grams and discover a radio that does all bands and modes, the Icom IC-705 with a battery, but no antenna. The Yaesu FT-817, FT-817dn and FT-818 weigh 70 grams more, but that weight includes both a battery and antenna. Of course there are other options. For example, there's the (tr)uSDX by Manuel DL2MAN, and Guido PE1NNZ, does 80m, 60m, 40m, 30m and 20m, CW, SSB, AM and FM. Comes in a kit, weighs 140 grams. It's not on RigPix, so I only know about it because it was mentioned by Dave KZ9V. Similarly, I bumped into, wait for it, a single transistor transceiver called the Pititico, in case you're wondering, Pitico means very small in Portuguese and Pititico means very very small. Designed by Miguel PY2OHH, it comes in various revisions, including one by Ciprian YO6DXE, also known as DX Explorer on YouTube, complete with a circuit board design, and with some modifications can do AM in addition to CW. It's also not in the RigPix database and I have no idea what it weighs. The point being that this rundown is intended as a starting point to explore how small you can really get and still activate the Park or Peak you intend to. While you're contemplating weight, remember to account for power, control, and most importantly an antenna or six. Again, big thank you to Janne SM0OFV, for the rigpix.com website. Also, thank you for the memories of the Spectravideo SV-318 and SV-328, the last time I bumped into one of those was in 1980-mumble when I was working in a computer shop on the Haarlemmerstraat in Leiden, Mr. Micro Zap, if you're curios.

Interview with Sam Riggall, Managing Director & CEO of Sunrise Energy MetalsOur previous interview: https://www.cruxinvestor.com/posts/sunrise-energy-metals-srl-400m-for-nickel-cobalt-developer-1954Recording date: 26th August 2025Sunrise Energy Metals (ASX:SRL) is developing what would become the world's first primary scandium mine in New South Wales, Australia, as global supply chains face unprecedented disruption from China's strategic export controls. The company's Syerston project aims to address Western nations' urgent need for secure access to this critical technology metal.In April 2025, China imposed sweeping export restrictions on scandium, classifying it as a dual-use material with both civilian and military applications. This decisive move has effectively severed Western access to 85% of global refined scandium supply and 100% of metallized scandium required by the semiconductor industry. CEO Sam Riggall describes the situation as creating "inherent limitations that Chinese supply will never be able to service in western markets going forward."The supply crisis comes at a critical juncture for scandium demand across three strategic sectors. In semiconductors, scandium enables the radio frequency filtering that made 5G technology possible, with military applications operating up to 13 GHz and next-generation technology proven to work beyond 20 GHz. The aerospace industry values scandium-aluminum alloys for their exceptional strength-to-weight ratios, while the fuel cell sector relies on scandium for enhanced performance and longevity in solid oxide systems.Sunrise's geological advantage positions it uniquely to capitalize on this supply vacuum. While Chinese producers extract scandium at concentrations of 10-20 parts per million from waste streams, Sunrise's deposit contains 600-700 ppm grades - a 70-fold concentration advantage. "When you look at primary mine supply, particularly high concentration, you cannot find a lower cost point than what you will get out of the ground in central New South Wales," Riggall emphasizes.The project's strategic importance extends beyond economics. At planned capacity of 40-50 tons annually, Sunrise could theoretically replace 100% of China's current production, addressing critical national security concerns for Western defense contractors. The company expects to complete its feasibility study by September 2025, with estimated capital requirements around $100 million and an 18-month construction timeline, positioning it to meet urgent Western supply security needs in this pivotal technological battleground.View Sunrise Energy Metals' company profile: https://www.cruxinvestor.com/companies/sunrise-energy-metalsSign up for Crux Investor: https://cruxinvestor.com

Using an SDR as measuring equipment

Play Episode Listen Later Aug 23, 2025 5:14

Foundations of Amateur Radio The other day I stumbled on a random post by Gary N8DMT which caused me to view the world in a different way. The post outlined combining a PlutoSDR and an application called SATSAGEN to measure the frequency characteristics of a coupler. Aside from a detailed description, the post includes a couple of excellent photos showing the PlutoSDR connected to the coupler and the output piped back into the Pluto. Before I continue, a PlutoSDR is a Software Defined Radio or SDR, officially it's called the ADALM Pluto Software Defined Radio Active Learning Module. It's essentially a full-duplex radio and computer in a box. It runs Linux and connects to the world via USB, and of course radio, unofficially between 70 MHz and 6 GHz. I've talked about this device before. When I say full-duplex, I mean that it can transmit and receive at the same time. Gary's post triggered something unexpected in me. The notion that you could use two patch leads, one connected to the transmitter, the other connected to the receiver, joined together by a device that you might want to test. It immediately reminded me of another device that was given to me, a NanoVNA, a device that's specifically designed to measure things like impedance, frequency response, generate Smith charts and all manner of other characteristics. Not only that, it also reminded me of another device, a TinySA, specifically designed to analyse spectrum and to generate signals. Both the NanoVNA and TinySA are lovely tools, but in looking at the post it suddenly occurred to me that their functionality, at least superficially, appears to mirror the PlutoSDR, in that you can create a signal and then measure that signal. Turns out that I'm not the first to make this observation. For example, the YouTube channel "From Concept To Circuit" goes through the process of describing precisely the concepts behind both a spectrum analyser and a network analyser while showing the programming code in Python. The channel also provides that code in a GitHub repository, which includes several other very interesting examples, like a beamforming transmitter as well as a beamforming receiver, also covered on YouTube. Another example is a tool I already mentioned, SATSAGEN, by Alberto IU1KVL, which implements a wideband spectrum analyser. Although it's Windows only, Alberto includes information on how to run it using Wine under Linux and MacOS. As a bonus, SATSAGEN in addition to the PlutoSDR, also supports RTL-SDR dongles, HackRF, USRP, RSP1, AirSpy, and many others. If text is more your thing, "retrogram-plutosdr", shows a spectrogram in your terminal window. Check out the "r4d10n" GitHub repository belonging to Rakesh VU3RGP, who says that the "retrogram" project is "hacked from" the "RX ASCII Art DFT" example, which you can find on the Ettus Research GitHub repository. One thing to consider is that the various GitHub repositories I've pointed at, will give you access to the moving parts of how all this works. I will mention that my favourite tool in this space continues to be GNU Radio, but I understand that you might not want to roll your own tool from parts. That said, rolling your own is in my experience a great way to discover precisely what you don't know and to come away learning more, but then, that's just me. Regardless of your chosen tool, I think the takeaway should be that when you try something new, even if it's only new to you, the idea of writing down what you discovered and sharing it, is a fantastic way to grow our community. Remember, just because something is old hat to you, doesn't mean that it is to the person you share it with. Besides, based on the current global birth rate, there's at least a thousand babies born during the past four minutes, some of whom will become radio amateurs, so, share. Said differently, if you come across a person who has never heard of the "Diet Coke and Mentos" thing, it's your job to immediately drag them to the nearest grocery store and introduce them. In case you're wondering, xkcd 1053. Now, I'm going to update the firmware on my PlutoSDR and have a play, I already know about the Mentos, but if you don't, you're in for a treat. What are you going to do next? I'm Onno VK6FLAB

Welcome to your weekly UAS News Update. We have four stories for you this week: SiFly sets world record for endurance, Inspired Flight releases a new controller, FreeFly Fest, and a man arrested in Florida for allegedly crashing a drug-loaded drone into someone's house.First up this week, California-based drone manufacturer SiFly has officially set a new Guinness World Record for flight endurance. Their Q12 prototype quadcopter completed a flight lasting an incredible 3 hours and 11 minutes. This absolutely shatters the previous record for a small, electrically powered multi-rotor drone by almost a full hour. The record-setting flight took place on July 26th in California's Salinas Valley and was certified by an official Guinness adjudicator on-site.Inspired Flight Technologies has just launched a new ground control station, the GS-ONE. This is a rugged, handheld controller aimed squarely at professional operators in commercial, industrial, and government sectors. It's designed to integrate seamlessly with Inspired Flight's own IF800 Tomcat and IF1200 UAS platforms.The GS-ONE features a 7-inch, glove-compatible touchscreen that boasts 2,000 NITs of brightness. That's going to be fantastic for a sunlight-readable experience out in the field. It has an NDAA-compliant 2.4 GHz radio with up to 6 miles of range and hot-swappable batteries that provide up to 5 hours of continuous runtime. The whole thing is housed in an IP55-rated enclosure for durability. On the inside, it's running Android 14 on a Qualcomm QCS6490 processor with 8 gigs of RAM and 128 gigs of storage. It's also packed with connectivity, including LTE, WiFi 6, and Bluetooth 5.2. We visited FreeFly for their yearly partner's event in Washington State. It was packed with announcements, including: Alta X Gen 2, A Firmware update for first Gen Alta X, FreeFly Platforms are back on Blue List, Several Astro Max upgrades, Ember toolbox for FreeFly's high speed cameras, A 1,000,000 lumen spotlight light called the Flying Sun, and even more cool LiDAR and camera tech. Also at the show was a Verizon demo where they flew a FreeFly Astro Max from both Florida and from Alaska using 4 and 5G. Pilot Institute is hosting three separate workshops. On September 2nd, join me, Vic Moss, Amy Wiegand, and Jared Janacek for a deep dive into the regulations, technology, and business strategies that are shaping the future of the drone industry.Then on September 3rd, I'm personally teaching a workshop on how to build your drone business.
