GB2RS News Sunday, the 28th of September 2025 The news headlines: What are your must-see presentations at this year's RSGB Convention? The RSGB invited the MP for Buckingham and Bletchley to the RSGB National Radio Centre for a private visit Listen out for today's special 70th anniversary GB2RS broadcasts Before we begin today's news bulletin, we would like to share a special message from the RSGB President Bob Beebe, GU4YOX, to mark the 70th anniversary of GB2RS. Bob says, “It is with a profound sense of respect and appreciation that today we mark the 70th anniversary of the GB2RS News service. Since 1955, volunteers have given their time and their voice to keep our radio community informed, connected, and inspired. For many of us, GB2RS has been a constant and familiar presence in our radio lives. On behalf of the RSGB, I extend my heartfelt thanks to all who have played a part in this remarkable story for the last seventy years. Today, we honour their legacy and reaffirm our commitment to the values and spirit that the GB2RS News service so proudly represents.”  And now we move to today's news items. The programme for this year's RSGB Convention has nearly 50 presentations for you to enjoy, including leading industry speakers such as Mike Walker, VA3MW from FlexRadio and Hans Summers, G0UPL from QRP Labs. There will also be well-known names such as Neil Smith G4DBN, RadCom Technical Editor Peter Duffett-Smith GM3XJE, Brian Coleman G4NNS and Walt Hudson K4OGO, known to many as ‘Salty Walt'. This annual RSGB event is your only opportunity within the UK to have access to this level of knowledge, learning and networking opportunities. As well as a packed full lecture programme, there will be nearly 20 special interest groups in attendance, so if you are thinking of pursuing a different area of the hobby, this is the perfect time to explore your options. To guarantee a place, you will need to purchase a ticket online via rsgb.org/convention before advance sales close on Sunday the 5th of October. Buying your ticket online not only guarantees your place, but it also saves you money when compared to on-the-door ticket prices. If you are arriving on Friday, why not join a private tour of Bletchley Park at 2.30 pm, which has been arranged especially for Convention attendees. In addition to this, and new for this year, RSGB National Radio Centre volunteer Patrick, 2E0IFB, will be running an informal introduction on getting started with low-earth orbiting satellites. The RSGB Convention takes place from the 10th to the 12th of October at Kents Hill Conference Centre in Milton Keynes. The RSGB was pleased to welcome Callum Anderson, MP for Buckingham and Bletchley, to the RSGB National Radio Centre at Bletchley Park last week. Callum enjoyed seeing the history of radio, watching live CW contacts and listening to his voice coming back from space, having been relayed via a satellite. Callum was invited to meet a small group of senior RSGB representatives who emphasised the important role of amateur radio in encouraging young people into an engineering career. Getting involved in Science, Technology, Engineering and Maths activities gives a great foundation that could lead some young people to follow in the footsteps of radio amateur pioneers who led the development of many wireless technologies that we rely on today. Most importantly, the visit gave the RSGB an opportunity to show the problems that ElectroMagnetic Disturbance can cause to wireless reception. Examples of EMD include household appliances, Broadband FTTC and green energy from solar panels and windfarms, where the signal levels are thousands of times stronger than the expected levels given in ITU recommendations. EMC Chair John Rogers M0JAV and Board Chair Stewart Bryant G3YSX explained that unless the year-on-year increases in background noise are stopped, many critical services and infrastructures could be impacted soon, just as the amateur radio bands are today. The RSGB looks forward to meeting again with Callum, who is the Parliamentary Private Secretary for Science, Innovation and Technology. Don't forget to listen out for three special one-off broadcasts from the RSGB National Radio Centre today. The broadcasts are part of the celebrations, which are taking place to mark the 70th anniversary of GB2RS. Listen out at 1 pm, 2.30 pm and 4 pm. Go to rsgb.org/gb70rs  for details of frequencies and newsreaders. All listeners are welcome to join the pre- and post-News nets, which will be operating using the special event station GB70RS. The RSGB LoRa high-altitude balloon launch took place on Saturday, the 20th of September and was a great success despite tricky weather conditions, which included rain and high winds. The balloon soared at a peak altitude of 48,556 feet before landing in a remote location in the Thursden Valley. Winners of the competition to win a £200 Moonraker voucher will be announced at the RSGB 2025 Convention on Sunday, the 12th of October. If you're wondering what you can do with your LoRa tracker now that the RSGB challenge has finished, go to rsgb.org/lora-balloon for a handy guide on how you can continue the fun.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 25th of September Last week was good for HF propagation for a number of reasons. Firstly, we are now entering autumn, which offers better propagation prospects than summer. Secondly, the solar flux index has remained high at up to 184 as of last Thursday, the 25th. We had a week of near-normal geomagnetic conditions, with a low Kp index, no Earth-directed coronal mass ejections, and a relatively quiet solar wind. These have all combined to give excellent HF propagation, including openings on the 10m band using FM and transatlantic 10m contacts being possible in the afternoon. The maximum usable frequency, or MUF, over a 3,000km path, according to Propquest, has mainly been in excess of 30MHz during daylight hours. The KQ2H repeater in upstate New York, with an output frequency of 29.620MHz, has been loud at times in the afternoon and is a good indicator of HF propagation. Expect it to get better as we enter October. Other US stations have also been heard on the 10m band using FM, including one in Ohio. Steve, G0KYA, was surprised to hear the GB3XMB 10m beacon on 28.287MHz from Waddington, Lancashire this week. Steve remarked that it is 175 miles to Norfolk as the crow flies. He said that the signal didn't sound like backscatter, so that's quite a distance for 10m ground wave. Another DX worked, according to CDXC, included FP5KE, the St. Pierre and Miquelon DXpedition. The station could be heard on everything from Top Band to 10m. V6D in Micronesia has been worked on the 40 and 17m bands using CW. Other highlights include D2USU in Fiji on the 12m band using FT8, and 9Y49R in Trinidad and Tobago on the 10m band using FM. Next week, NOAA predicts the solar flux index may fall to the 159 to 170 range. Geomagnetic conditions are predicted to be poor tomorrow, the 29th, with a Kp index of 5, and again between the 3rd and 5th of October, also with a predicted Kp index of 5. Expect decreased MUFs for a few days until the ionosphere recovers. And now the VHF and up propagation news from G3YLA and G4BAO The next week or so looks to be typical for autumn. It will be a mix of Atlantic weather systems bringing lows and their fronts, which may offer some rain scatter for those on the GHz bands. The other side of the coin is areas of high pressure or mostly weak ridges, in this case mainly affecting the south and east of the country. This is the point where Tropo operators can move in with paths probably favouring the North Sea and Scandinavia up to this weekend and then across to the continent and down to Spain during the coming week. It is worth remembering that Tropo can exist throughout the 24 hours across water and along coasts like the North Sea and English Channel, although the portion of a path overland can weaken during daytime. The meteor scatter prospects remain in the random territory, so they are best in the early morning. Recent activity with geomagnetic disturbances suggests that aurora should continue to be part of the operating list in the coming week. Check for a hollow note or warble on HF signals and for a Kp index greater than 5, then consider turning your VHF arrays to the north. For EME operators, Moon declination reaches its minimum tomorrow, the 29th, so from then on, we will see lengthening Moon windows and increasing peak elevation. The Moon's distance from Earth started to decrease after apogee on Friday, the 26th, meaning path losses are falling. 144MHz Sky noise will be high today, the 28th, and peaks at around 2800 Kelvin tomorrow, the 29th, before dropping back to low for the rest of the week. And that's all from the propagation team this week.

Procesadores Snapdragon X2 Elite y X2 Elite Extreme llegan con 18 núcleos, 80 TOPS de IA y promesa de gran eficiencia  Por Félix Riaño @LocutorCo  Qualcomm presentó en el Snapdragon Summit 2025, celebrado en Hawái, sus nuevos procesadores para computadoras portátiles: Snapdragon X2 Elite y Snapdragon X2 Elite Extreme. Estos nombres marcan la segunda generación de la apuesta de Qualcomm para llevar su experiencia en chips de teléfonos móviles al mundo de las laptops.  En la presentación, Qualcomm explicó que estos procesadores están pensados para competir directamente con Intel, AMD y Apple, tres de los gigantes que han dominado durante años la industria de los computadores. La diferencia es que ahora se habla de integrar más potencia de cálculo, un consumo de energía mucho más eficiente y capacidades de inteligencia artificial nunca vistas en esta categoría.La propuesta de Qualcomm suena sencilla: laptops con Windows que sean rápidas y confiables, que respondan bien al abrir programas de ofimática o al editar fotos y videos, y que puedan manejar videojuegos modernos con gráficos fluidos. Todo esto con la ventaja de que la batería pueda durar jornadas completas, incluso varios días en uso moderado. Qualcomm quiere que Windows sobre arquitectura ARM —un tipo de procesador muy usado en móviles— se perciba tan natural y poderoso como lo es hoy Apple Silicon en los MacBooks.  ¿Y qué significa exactamente todo este mar de siglas técnicas?  Snapdragon es la marca de procesadores de Qualcomm, usada en móviles y ahora en computadores. El nombre X2 Elitemarca la segunda generación de la línea X, que debutó en 2023 con el Snapdragon X Elite. La variante X2 Elite Extremees la más poderosa, con mayor velocidad y eficiencia.La CPU Oryon es el diseño propio de Qualcomm basado en arquitectura ARM. ARM es la sigla de Advanced RISC Machines, un tipo de arquitectura de procesadores conocida por ser eficiente en consumo de energía. Este salto de Qualcomm incluye núcleos que alcanzan frecuencias de hasta 5,0 GHz (gigahercios, medida de ciclos por segundo), lo que permite más operaciones en menos tiempo.Los chips están fabricados en 3 nanómetros. Un nanómetro es una milmillonésima parte de un metro, lo que muestra la miniaturización extrema en la industria.  El mercado de laptops con Windows llevaba décadas dominado por Intel y AMD. Microsoft Surface, una de las líneas más visibles de computadores con Windows, abandonó Intel en algunos modelos al adoptar Snapdragon X. Ahora Qualcomm quiere consolidar ese espacio. Pero la tarea no es fácil: Apple con su M1 en 2020 cambió la percepción de la potencia de chips ARM en computadores. Intel y AMD siguen dominando en potencia bruta y compatibilidad de software.El reto principal de Windows sobre ARM es la compatibilidad. Muchos programas diseñados para arquitecturas x86 (el estándar de Intel y AMD) aún necesitan traducción para correr en ARM. Qualcomm promete que con el X2 Elite y el X2 Elite Extreme habrá mejoras en videojuegos, productividad y hasta en aplicaciones de Adobe como Photoshop y Premiere. La promesa es “multi-day battery life”: autonomía de varios días, que en la práctica podría ser de 14 a 18 horas de trabajo continuo, según lo visto en la generación anterior.  Los datos técnicos impresionan. El Snapdragon X2 Elite Extreme ofrece hasta 75 % más rendimiento que competidores al mismo consumo de energía, según Qualcomm. El NPU, o Neural Processing Unit (Unidad de Procesamiento Neural), alcanza 80 TOPS. TOPS significa Tera Operations Per Second, o un billón de operaciones por segundo, y es la métrica clave para medir potencia en inteligencia artificial. Esto abre paso a funciones como escalado de imagen en tiempo real, generación de fotogramas adicionales y asistentes locales más rápidos.El GPU, o Graphics Processing Unit (Unidad de Procesamiento Gráfico), también sube de nivel con frecuencias de hasta 1,85 GHz y soporte para DirectX 12.2 Ultimate y Vulkan 1.4, que son interfaces de programación para videojuegos modernos. Las laptops podrán conectar hasta tres pantallas en 4K a 144 Hz o en 5K a 60 Hz.La memoria admitida es LPDDR5x, que significa Low Power Double Data Rate 5x, memoria de bajo consumo con alta velocidad, con soporte de hasta 128 GB. Además, los chips incluyen caché de hasta 53 MB, clave para acelerar procesos repetitivos.  En el evento, Qualcomm mostró conceptos futuristas: un PC en forma de frisbee y otro cuadrado como un posavasos que se conecta a pantallas externas. Aunque no sean productos finales, muestran cómo la miniaturización abre paso a nuevos diseños.Los primeros computadores con Snapdragon X2 Elite y Elite Extreme se esperan en la primera mitad de 2026. Fabricantes como Razer ya anunciaron compatibilidad de su software Synapse con esta arquitectura, mientras que Epic Games habilitó su sistema Anti-Cheat para que Fortnite sea jugable en laptops Snapdragon. También se integrarán herramientas como Voicemod, que con el NPU permitirá cambiar la voz en tiempo real durante partidas sin afectar el rendimiento.El anuncio de Qualcomm también es parte de una tendencia: Apple con sus chips M-series, AMD con sus Ryzen AI y ahora Qualcomm con Snapdragon X2 apuestan por integrar potencia de cómputo e inteligencia artificial en cada dispositivo. El resultado: más duración de batería, más rendimiento gráfico y PCs listos para la era de la IA.  Los nuevos Snapdragon X2 Elite y Elite Extreme son la jugada fuerte de Qualcomm para laptops con Windows. Traen 18 núcleos, 80 TOPS de IA y promesas de baterías que duran días. ¿Podrán realmente enfrentar a Intel, AMD y Apple? Cuéntamelo en comentarios y escucha más en Flash Diario.  Qualcomm lanza Snapdragon X2 Elite y Extreme: 18 núcleos, 80 TOPS y batería para varios días en laptops Windows ARM.  

GB2RS News Sunday, the 21st of September 2025 The news headlines: Secure your ticket for the RSGB 2025 Convention before online ticketing closes A reminder to identify yourself clearly when operating The RSGB Outreach Team launches its first official DMR Youth Net Tickets for the RSGB Convention at Kents Hill Conference Centre in Milton Keynes are still available to purchase online, but hurry as advance sales close on Saturday the 4th of October.

Last week we said that it looked like someone had thrown a switch on the Sun and all the sunspots had vanished. Well, this week we're pleased to report they're back! We have eight sunspot groups, spread evenly throughout the Sun's hemispheres. Interestingly, the northern hemisphere sunspots are close to the equator, which is what you would expect at this point in the latter part of the solar cycle. The southern spots are somewhat higher in latitude, perhaps indicating that there might still be the potential for a double peak. On Thursday the 18th, the solar flux index stood at 147 and the Kp index at 2. This suggests that HF conditions might be pretty good, at least until the next geomagnetic disturbance. There have been no M- or X-class solar flares over the past week. The solar wind speed dropped from a high of 800 kilometres per second on Tuesday the 16th, to a more reasonable 538 kilometres per second on Thursday the 18th. However, the Bz has been pointing south at times, which can cause problems with a raised Kp index. The maximum useable frequency, or MUF, over a 3,000km path generally allows for operation between 21 and 24MHz during daylight and 7 and 10.1MHz at night. At 0845UTC on Thursday the 18th, a quick check of the NCDXF beacons on 21.150MHz showed reception of CS3B in Madeira and 4X6TU in Israel. On 24.930MHz, 4S7B in Sri Lanka, ZS6DN in South Africa, and CS3B in Madeira could be heard. On 28.200MHz the only audible beacon was 4X6TU in Israel. The NCDXF beacons are a quick way to check worldwide HF propagation in just three-minutes per band, from 20 to 10m. For more details visit ncdxf.org/beacon HF DX this week has included FP5KE on St Pierre and Miquelon, which is operating until the 26th of September. PJ7K on St. Maarten, which is active until the 22nd of September, was worked; and VK9NT on Norfolk Island, which is operating until the 27th of September, also made it into UK logbooks. Check the DX cluster for the latest spots. Next week NOAA predicts the solar flux index will remain in the range of 125 to 135. The Kp index is forecast to remain low at 2 all week. A coronal hole threatens to push the Kp index higher, perhaps late today, the 21st, or tomorrow, the 22nd.   And now the VHF and up propagation news from G3YLA and G4BAO The first part of the coming week will be under the influence of the unsettled weather pattern with lows and fronts affecting the British Isles. So, it feels like there will be a few more days for the GHz rain scatter folk to play. Be aware that even among low-pressure systems there can be fleeting moments of good Tropo. On Friday the 19th there were ideal Tropo conditions over southern Britain and south across Biscay to Spain as well as east across the North Sea. The big change takes place on Wednesday as an area of high pressure starts to build over the UK. This could last through to the end of the week. So, there is plenty of time to develop some good Tropo conditions over large parts of the UK and near-continent. There will probably be an elevated inversion some 1 or 2km above the surface. This will be caused by the high itself and may provide ducting conditions throughout the 24-hour period. This may be supported by temporary surface inversions overnight due to the ground cooling. These features tend to take a while to establish, which suggests that the latter part of the coming week may be the best time to operate. The effect will only just be starting to influence conditions over the western side of the UK for the SHF UK Activity Contest on Tuesday the 23rd. Regarding the aurora prospects, it feels like we should be keeping a watch throughout this autumn period when the Earth's magnetic field couples with the solar wind more effectively. Earlier last week the Kp reached 5, which is a good trigger to get interested in beaming north for those fluttery auroral signals. Meteor scatter remains in between events at the moment with no major showers in the period. So, it's random meteors only which, as we know, tend to favour the early morning, pre-dawn hours. We are outside the traditional Sporadic-E season now but, as you may have noticed on the Propquest graphs, there has been the occasional spike on the foEs plot up to 5MHz or so. This is plenty to generate some strong short-skip European signals on the HF bands, especially 10m. In the morning on Wednesday the 17th, Sporadic-E was probably triggered by the powerful jet stream moving east over the near continent. There may well be further occasions with strong jet streams during the next week, so keep checking the NVIS tab at propquest.co.uk to see if the foEs trace spikes again. Now for an EME update. Moon declination is decreasing, from its maximum on the 14th of September. The Moon's distance from Earth is also increasing until apogee on the 27th and 28th of September. This means path losses are growing over the next week. Sky noise will remain low until the 29th and 30th of September. And that's all from the propagation team this week.

Imaginez un Wi-Fi capable de franchir les murs, là où les ondes les plus courtes se brisent d'ordinaire. C'est la promesse qu'esquissent des chercheurs de Princeton, qui viennent de tester avec succès un faisceau “Airy” piloté par intelligence artificielle. Leur découverte pourrait ouvrir la voie à un successeur crédible du Wi-Fi 7, alors que la bande sous-térahertz s'impose comme le nouvel eldorado du sans-fil.Dans leur expérience, un réseau neuronal a appris à sculpter l'onde radio pour lui faire suivre une trajectoire courbe, un peu comme une balle liftée au tennis. Résultat : le signal contourne un obstacle en temps réel, sans s'effondrer. Trois microsecondes suffisent au système pour réagir lorsqu'un passant s'interpose. Une réactivité permise par une approche « informée par la physique » qui évite des calculs trop lourds. Concrètement, de simples modules actifs de metasurface reconfigurent phase et amplitude du signal, sans miroir ni mécanique complexe. Les résultats impressionnent : là où un balayage classique perd des dizaines de décibels, le lien reste stable, même hors champ visible. L'essai a été mené à 120 GHz, une fréquence clé pour la prochaine génération de Wi-Fi. Pour passer du laboratoire aux box domestiques, deux défis demeurent : miniaturiser ces plaques actives et réduire leur consommation. Le saut de performance, lui, fait rêver. Quand le Wi-Fi 7 plafonne à 46 gigabits par seconde sur un canal de 320 MHz, la bande sous-térahertz ouvre la perspective de débits au téraoctet par seconde. De quoi envisager des usages aujourd'hui hors de portée : réalité virtuelle sans câble, streaming en 16K, robotique collaborative. Ici, ce n'est plus la portée qui compte, mais la stabilité du lien à courte distance. Si le marché suit, les premiers routeurs capables de “plier” leurs ondes pourraient apparaître d'ici la fin de la décennie. Reste à standardiser les algorithmes, adapter les protocoles WLAN et produire des metasurfaces abordables. En attendant, une chose est sûre : dans le futur du Wi-Fi, les murs ne feront plus la loi.

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

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 11th of September As of Thursday, the 11th of September, it looked like someone had thrown a switch on the Sun to turn off all new sunspots! Unless there is a big change, there will be no sunspots visible on the Sun's surface today, the 14th. It is clear we are no longer at solar maximum. A bigger problem is a large coronal hole on the Sun's surface, which is rotating to be Earth facing. It is on the Sun's equator, so it is ideally placed for maximum disruption to the Earth. A high-speed solar wind stream should reach Earth by the 14th of September, and geomagnetic storming may be possible at higher latitudes. Expect maximum usable frequencies, or MUFs, to drop and trans-polar paths to be affected once the Kp index rises. HF is now starting to improve as we head towards mid-September. By 1000UTC, Propquest shows that the MUF over a 3,000km path can be as high as 31MHz, as long as the Kp index stays low. This should continue to improve as we head into October. The best DX last week continued to be T30TTT in Western Kiribati, this time on the 40 and 17m bands using FT8. 9J2FI in Zambia also put in an appearance on the 17m band using FT8. TZ4AM in Mali was spotted on the 15m band using SSB. For Morse enthusiasts, HC5AI in Ecuador was working on the 15m band using CW, according to the CDXC Slack chat group. NOAA predicts that the solar flux index will start the coming week at 125 but then gradually improve to reach 145 by the end of the week. As mentioned earlier, the Kp index is set to reach 4 or 5 between the 14th and 16th of September due to the coronal hole. And now the VHF and up propagation news from G3YLA and G4BAO The present spell of unsettled weather is likely to remain the main driver of weather-related propagation modes for the next week. Low-pressure systems are following the jet stream across the Atlantic and over the UK, which is a typical track for this time of the year. This means that we should expect to experience the odd example of rain scatter for the GHz operators, and occasional strong winds will start to test that we have our antennas in good order after the quieter weather during the summer. This is not to say that there won't be any Tropo, but we will have to look for it carefully. In a mobile weather pattern such as this, the periods of high pressure tend to act as separators between the lows and, as a result, they usually move with similar speed. This makes them short-lived and thus not particularly good at establishing strong inversions for Tropo. There are two low-grade possibilities. One is around Tuesday the 16th as a weak transient ridge moves across the country. The second will be as another weak ridge moves across on Friday, the 19th. The meteor scatter situation is still pretty much in a random activity state, although there was a minor shower of the Epsilon Perseids, which peaked on the 9th and may have a few left in the tail-off. However, in general, it's more realistic to assume we're dealing with random activity. Aurora, on the other hand, has been putting in an appearance lately, so keep watching the Kp index for values climbing above 5. Now for an update on EME. Today, the 14th, marks the Moon's maximum declination – its highest point in the sky. Perigee, when the Moon is at its closest point to Earth, was passed on September the 9th, so path losses are increasing. Sky noise is low and will remain so until the 20th to 22nd, when the new Moon is very close to the Sun. And that's all from the propagation team this week.

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. What lightweight adventures are you looking for next? I'm Onno VK6FLAB

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

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. And on September 4th, Jared will teach you his professional mapping process. Spots for each day are limited and they are filling up. Go to pilotinstitute.com/cuav to see the details and secure your seat.A story that falls squarely into the "what not to do with your drone" category. Out in Lutz, Florida, a 49-year-old man allegedly crashed his drone into a residential home. According to the Hillsborough County Sheriff's Office, the drone was allegedly carrying multiple bags of methamphetamine and fentanyl. In Post Flight, our show where we share more of our opinions, we'll be talking about these stories along with even more nuggets we've found in the Part 108 NPRM and Ag Eagle, who launched a new multispectral camera. We'll see you on Monday for the live and for Post Flight in the premium community! https://www.commercialuavnews.com/inspired-flight-introduces-new-ground-control-stationhttps://www.fox13news.com/news/video-drone-carrying-drugs-crashes-home-suspect-arrestedhttps://dronelife.com/2025/08/20/siflys-q12-breaks-drone-endurance-barriers/https://freeflysystems.com/

QSL via Logbook of the World, eQSL, QRZ.com or via EA5GL. To celebrate the International Amateur Radio Union's 100th anniversary, members of the Atlantic Coast DX and Contest Group are active as CG9IARU throughout August. The station was spotted recently on the 20m band using SSB. QSL via VE9CF. See QRZ.com for more information.  Now the DX news Aldir, PY1SAD is active as 8R1TM from Guyana until the 23rd of September. He is operating CW, SSB and digital modes on all bands and via satellite. QSL via Logbook of the World, eQSL, QRZ.com, or directly to PY1SAD. Don, KW7R is active as V73KW from the Marshall Islands until September. He operates CW and FT8 on various bands. QSL via Logbook of the World. Now the contest news Today, the 24th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. On Tuesday the 26th, the RSGB 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. The World Wide Digi DX Contest starts at 1200UTC on Saturday the 30th and ends at 1200UTC on Sunday the 31st of August. Using FT4 and FT8 on the 160 to 10m bands, where contests are permitted, the exchange is your four-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 21st of August Last week was relatively good from an HF propagation standpoint, with only a few periods with an elevated Kp index thanks to a high-speed solar wind stream from a coronal hole. The Kp index hit 4.67 on the 19th of August and 4 again on the 20th due to the solar wind hitting earth at more than 600 kilometres per second. Luckily, the interplanetary magnetic field remained mostly neutral, or north-facing, and the density was low, saving us from more disruption. Meanwhile, the solar flux index declined to 120 by Thursday the 21st. This is still high enough to affect the ionosphere, but well down on recent highs in the 140s and 150s. The daytime critical frequency has mostly remained above 7.5MHz, meaning the 40m band has managed to remain good for inter-UK contacts. This has also meant that maximum usable frequencies, or MUFs, over a 3,000km path hit 21MHz and even 24.9MHz at times. Nighttime critical frequencies have been around 5MHz, giving an MUF over 3,000km of below 14MHz and sometimes even as low as 10MHz. It may be another month or so before we see daytime F2-layer openings starting again on 28MHz. In the meantime, focus your efforts during daylight on 21MHz and below. T30TTT in Western Kiribati remains one of the DX stations to chase, mostly on 18 and 21MHz. The operators are alternating between using CW, SSB and FT8. Other choice DX worked included Jim, E51JD on South Cook Islands who has been active on the 17m band using SSB. TY5AD in Benin, Africa has been worked on the 10m band using FT8. And 3G1P, an IOTA DXpedition in Chile, was logged on the 15m band using SSB. Closer to home, today, the 24th, is the last chance to work OG0C on the Aland Islands. Next week, NOAA predicts that the solar flux index will remain in the 120s, until the end of the month when it could rise to 130 and even 150. Unsettled geomagnetic conditions are forecast for the 28th of August when the Kp index could hit 4. Otherwise, make the most of the relatively settled conditions over the first half of next week to work some choice DX! And now the VHF and up propagation news from G3YLA and G4BAO After this weekend, the weather changes from a Tropo high pressure pattern to an unsettled story with areas of low pressure and fronts together with wind and rain. This will remove any Tropo options and replace them with a possibility of rain scatter on the GHz bands. The auroral conditions have recently produced minor enhancements, although nothing too exciting so far radio-wise. It's worth noting that the autumn, along with spring, are times of the year when auroras are more likely. So, it's a good time of the year to keep abreast of the Kp index, especially if the Kp index goes above 5. We are at the tail end of the broader period of the Perseid meteor shower, ending today, the 24th. This leaves random meteor activity as the only option for a while. As those of you who are active in the mode already know, it tends to favour the early pre-dawn period for better chances of catching meteor scatter. Sporadic-E is hanging on for the last week or two of the 2025 season, but opportunities become much rarer. You'll need to keep a close watch on band reports to capture these increasingly fleeting events. In the main Sporadic-E season, there are usually two well-defined peaks of activity in the morning and late afternoon. However, in the tail of the Sporadic-E season you are just as likely to find it around the middle of the day as at any other time. The daily Sporadic-E blogs at propquest.co.uk  finish at the end of August, but in some years the last events have extended into the first week of September.  Moon declination is still positive, but falling, going negative on Monday. So, Moon window lengths and peak elevation will follow suit. Path losses are rising again as we approach apogee on Friday the 29th. 144MHz sky noise was low until lunchtime on Friday the 22nd, when the Sun and the Moon were very close in the sky. This continued throughout the Moon window on yesterday, the 23rd, and will revert to moderate-to-low next week.  And that's all from the propagation team this week.

Foundations of Amateur Radio Recently I discussed the idea of listening to the radio spectrum across the internet for the purposes of getting signal into your shack when radios, or in my case, antennas are causing you challenges. I continued to explore and discovered a project by Jacobo EA1ITI, called "radioreceiver". Behind that unassuming name lies a tool born in 2014, that allows you to plug an RTL-SDR dongle into your computer, open up your web-browser, and listen to the radio signals that your dongle can receive. In case you're unfamiliar, an RTL-SDR dongle is a small USB device, looks a lot like a USB thumb drive, jump drive, data stick or flash drive, basically a hunk of plastic with a USB connector on it. An RTL-SDR dongle generally also has some form of antenna connector. It's typically sold as a digital radio and digital television receiver, but websites like rtl-sdr.com sell purpose built ones. They can be found starting at about $15. I realise that this is using a local receiver, with a local antenna, but it's inside a web browser, which is half of what I expected. When you hit the play button in the bottom of the screen, you'll be prompted by your web browser to give permission to access your RTL-SDR dongle and the fun starts. You'll see a live waterfall, hear audio, and have the ability to tune to any frequency you can reach. Depending on your dongle, typically somewhere between 500 kHz and 1.76 GHz. The application consists of seven files, a total of 352 kilobytes that you can store on any web server and run, with one caveat, in order for your web browser to talk to your dongle, it needs to be served using HTTPS. Jacobo has set-up radio.ea1iti.es and I've set-up sdr.vk6flab.com, both showing the same tool. You'll find the code on my VK6FLAB GitHub repository, and of course on Jacobo's. There are some things you need to know. You will need to use a web browser that supports WebUSB, currently that's Chrome, Edge, Opera and several others, sorry, Safari and Firefox don't .. perhaps it's time to talk to Apple and Mozilla. All is explained if you click on the little question mark at the bottom of the screen, it will even tell you if the browser you're using to read the help is compatible or not. If you have an Android phone, you can run this tool too, although you will need to find a way to connect your dongle to your phone. I'm currently limited in my ability to test this and you may need to install some drivers on Windows and Linux, but MacOS and presumably Android, works out of the box. The software also supports offline operation, so you can load it as a Progressive Web App, or PWA, and use it in the field away from the internet. Did I mention that all the decoding is happening inside the web browser, so you can see which code is doing what .. and before you ask, yes, it's minimised in the browser, which you can make into human readable code, but when you look at the source, it shows precisely what is happening, all written in Node.js, TypeScript and JavaScript. It supports CW, SSB, AM, Narrow and Wideband FM and decodes stereo, something which none of my amateur radios do. You might be able to tell that I'm excited. It's because this is providing the basic functionality of a radio inside a web browser, and I didn't need to install it to get started. On the Macintosh I tested this on, I literally opened the web page, plugged in a dongle and hit play. Just so we're clear, just because this is using a web page on a web server, you accessing it will only give you access to your radio not mine. This of course opens the doors to all manner of other fun stuff which I'm expecting to play with for the next little while, and yes, this is also Bald Yak adjacent, I'm aware. In the meantime, you can play with this right now, sdr.vk6flab.com is the place to go. Word of warning, it's addictive and easy to forget it's a radio with an antenna plugged into your computer, so take precautions when electrical storms are about. Look forward to hearing what you discover. I'm Onno VK6FLAB

En 2019, Dojo s'annonçait comme l'un des projets les plus ambitieux de Tesla : un supercalculateur maison capable de traiter les flux vidéo envoyés par sa flotte de véhicules pour perfectionner conduite autonome et robotique. Au cœur du système, la puce D1, conçue en interne, devait libérer Tesla de ses fournisseurs traditionnels. Mais les retards techniques se sont accumulés, et les départs en série ont eu raison de l'initiative. Plusieurs cadres clés ont quitté le navire pour fonder DensityAI, une start-up développant des solutions similaires. En 2025, Peter Bannon, dernier chef du programme, les rejoint avec une vingtaine d'ingénieurs. Elon Musk confirme alors l'abandon de Dojo : Tesla se concentre désormais sur deux nouvelles puces, AI5 et AI6, produites avec TSMC et Samsung.L'histoire avait pourtant commencé avec de grandes ambitions : chaque puce D1 contenait 354 cœurs cadencés à 2 GHz, vingt-cinq d'entre elles formant un bloc de calcul de 9 pétaflops. L'objectif final ? Plus de 100 exaflops de puissance, grâce à 3 000 blocs assemblés. Un lancement prévu en 2024, déjà doté d'un investissement dépassant le milliard de dollars. Mais au fil des ans, les départs se sont multipliés : Jim Keller en 2018, Ganesh Venkataramanan en 2023, Milan Kovac, David Lau… et même Omead Afshar, proche collaborateur de Musk. Trop de pertes pour maintenir le projet à flot.Aujourd'hui, Tesla revoit sa stratégie : l'AI5 reste fabriquée par TSMC, l'AI6 sera produite par Samsung au Texas dans le cadre d'un contrat de 16,5 milliards de dollars jusqu'en 2033. Ces nouvelles puces, conçues pour l'inférence mais capables d'entraînement, équiperont les futures plateformes de robotaxis et systèmes robotiques. Pour les calculs les plus lourds, Tesla continuera à s'appuyer sur Nvidia et AMD. Un recentrage industriel et stratégique, qui promet des délais plus courts et une intégration rapide. Mais un contraste saisissant avec l'enthousiasme de septembre 2023, lorsque Morgan Stanley estimait que Dojo pourrait ajouter 500 milliards à la capitalisation de Tesla… Un rêve aujourd'hui rangé au placard.

On Thursday, the 14th, the RSGB 50MHz UK Activity Contest runs from 1900 to 2130 UTC. Using all modes on the 6m band, the exchange is a report and four-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 7th of August Over the last week, we had nearly ideal solar conditions for HF propagation. These included low geomagnetic indices and a reasonable solar flux index, hovering around the 150 mark. Other solar events of note included six M-class solar flares. The only stumbling block is the time of year, with summer seeing lower maximum usable frequencies, or MUFs, and poorer propagation due to changes in ionospheric chemistry. We will have to wait another month or so to see conditions pick up. The main HF DX this week has been T30TTT from Western Kiribati, mainly on FT8 and CW and focusing on the 20 and 17m bands. TJ1GD from Cameroon was worked on the 17m band using FT8. E51KEE on the South Cook Islands was logged on the 17 and 15m bands using CW. And finally, AH6KO in Hawaii was worked on the 15m band using CW. But this may all be set to change. A coronal mass ejection observed on Tuesday, the 5th, may deliver a glancing blow to the Earth's geomagnetic field. This may also coincide with an expected high-speed stream from a very large coronal hole on the Sun's surface. NOAA predicts that the Kp index could rise to 5 or 6. The hole is so large and elongated that we could see unsettled conditions occurring in the coming week. NOAA predicts unsettled geomagnetic conditions from the 11th to the 14th of August. It also predicts more unsettled conditions from the 18th to the 22nd, with a maximum Kp index of 5. Expect reduced MUFs and poor HF conditions, especially for paths over the poles. And now the VHF and up propagation news from G3YLA and G4BAO The main setting for the weather pattern over the next week is a tendency for high pressure in the south and lower pressure to the north of Britain. There may be some input from a low over France around the middle of the week. This might introduce some thundery showers and a chance of rain scatter on the GHz bands. Meanwhile, occasional weak frontal systems will bring patchy rain to the far northwest, but probably not so good for rain scatter opportunities. The Tropo at this time of year can be very good around the coasts and occasionally inland overnight. However, it tends to weaken inland during the heating of the day. Out at sea, temperatures remain fairly constant and maintain an ideal cool, moist layer at the sea surface overlain by a layer of warm, dry air from the land. This provides Tropo 24 hours a day, seven days a week. Mid-August is good for meteor scatter with the peak of the Perseids on the Tuesday night of the 12th and 13th. Apart from digital-mode QSOs, it's good for late summer evening sky watching. It is fascinating to listen to the VHF SSB meteor scatter frequencies while watching to get the full experience. It's a broad shower, so don't worry if you must pick a night either side of the peak. The chances of an aurora are not zero, with further minor alerts to remind us that it's worth checking. The main mode for DX is probably still going to be Sporadic-E, which has roughly another four weeks to run. Don't expect something every day, as it tends to become more random towards the latter part of the season. Moon declination is negative, but rising again, so Moon window lengths and peak elevation will increase. Path losses are also falling, reaching a minimum at perigee on Thursday, the 14th of August. 144MHz sky noise is low to moderate all next week. And that's all from the propagation team this week.

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

AC Infinity is revolutionizing indoor grow room automation with its latest smart grow technology ecosystem. Brand specialist Brandon from AC Infinity showcases how the new Controller AI+ – an AI-powered environmental controller – works with the AC Infinity app to dynamically adjust your grow tent climate by regulating fans, lights, pumps, and more. This intelligent controller learns your environment, smoothing out temperature and humidity swings (optimizing VPD) and eliminating the need for constant manual tweaks. We explore how these innovations make indoor growing easier and more efficient, giving growers the power to monitor and fine-tune conditions remotely via WiFi or Bluetooth right from a smartphone. In addition to the AI controller, the video introduces AC Infinity's wireless UIS dongles that eliminate cable clutter by linking devices to the controller over a secure 2.4 GHz signal. We demonstrate how one controller port can now manage multiple fans or lights wirelessly, streamlining your grow tent setup. You'll also see the new AI Power Strip, a smart outlet strip that lets you automate grow devices and plug-in sensors (like humidifiers, heaters, or CO₂ monitors) even without a main controller – an affordable entry point for smart grow automation. The discussion highlights AC Infinity's upgraded Cloudray S2 oscillating clip-on fans (Gen2), built for continuous 24/7 operation to keep air flowing, as well as their long-awaited smart dehumidifiers (in 3L, 5L, and 7L models) that maintain ideal humidity levels and even allow you to recycle the collected water for your humidifier. Finally, we touch on AC Infinity's comprehensive product lineup – from grow tents, LED lights, and climate controllers to nutrients (in partnership with Athena) – solidifying their status as a one-stop shop for fully integrated indoor grow systems. Throughout the interview, we emphasize AC Infinity's dedication to quality, innovation, and customer support, including active community engagement via the weekly “AC Infinity After Dark” podcast and frequent product giveaways.

This year marked the centenary of the unique mechanical Alexanderson Alternator transmitter at Grimeton near Varberg in Sweden. GB2RS Newsreader and NRC volunteer Brian Hardy, G4BIP, travelled to Sweden for a special 70th birthday trip with his partner Hilary, G7SOI. On the 2nd of July, they were able to watch SAQ being operated on a frequency of 17.2kHz as part of the celebration. Brian was even allowed to key up the station in advance of the formal transmission and send some test messages. Despite SAQ having a power output of 80kW, nobody came back to his CQ call! However, it was a big tick on his 'bucket list'! The station is usually fired up twice a year and is well worth a visit.

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

A new law restores the FCC's authority to auction spectrum and requires at least 800 MHz to be sold, potentially pulling it from the 6 GHz and CBRS bands currently used for Wi-Fi and rural broadband. While mobile carriers like AT&T and Verizon support the move for 5G expansion, critics warn it could slow Wi-Fi and harm small ISPs that rely on those bands. The law reverses earlier efforts to protect 6 GHz for unlicensed use and reflects growing pressure from the wireless industry, now backed by former FCC Chair Ajit Pai, who leads a major telecom lobby.

GB2RS News Sunday, the 13th of July 2025   The news headlines: The RSGB announces speakers for its annual Convention in October Get involved with chasing awards this summer RSGB Regional Representatives elect a new Regional Forum Chair The RSGB is delighted to announce that the Keynote Speaker for its 2025 Convention will be Professor Lucie Green. She is a Professor of Physics and a Royal Society University Research Fellow at the Mullard Space Science Laboratory of the University College London. She has also presented many TV and radio programmes, including The Sky at Night and Stargazing Live. During her talk, Professor Green will provide an update on the proposed Moon-Enabled Sun Occultation Mission, which she is working on with fellow UK researchers. The project will enable the team to study the conditions that create solar storms, leading to improvements in forecasts of space weather on Earth. As well as releasing details of the Keynote Speaker, the RSGB has published a teaser of its Convention programme. This includes Neil Smith, G4DBN, who will share his experience of taking complex ideas and turning them into stories that connect with wider audiences. Many of you will be familiar with Neil from the popular BBC series “The Secret Genius of Modern Life”, for which he recreated a device invented by Leon Theremin. Bill Rothwell, G0VDE, will show you that DXpeditions don't always need to involve masses of equipment, and that one person can make a successful trip with only the luggage they carry. RSGB Propagation Studies Committee member Gwyn Griffiths, G3ZIL, will explore Travelling Ionospheric Disturbances, whilst Brian Coleman, G4NNS, will give you the latest update on the UK Meteor Radar System. Read the full list of confirmed speakers by going to rsgb.org/convention  and selecting the “RSGB 2025 Convention speakers” option from the right-hand menu. The RSGB 2025 Convention is taking place at Kents Hill Conference Centre between the 10th and 12th of October. Book your ticket now and join like-minded people for a fun-filled weekend. Set yourself a challenge this summer and get involved with awards chasing. The RSGB awards are open to everyone, whatever your age, licence level and personal interests. They encourage you to push yourself further, learn something new and can even help you to make tweaks to your station to maximise performance. If HF is your mode, then visit rsgb.org/awards  and get involved with the IARU Region 1 Award, which encourages you to make contacts with member countries. If VHF or UHF is your preference, then challenge yourself to the 50MHz Continents and Countries Award. Several Foundation awards are aimed at getting new licensees on the air and helping build confidence. For younger RSGB members, there are two awards designed to show the breadth that amateur radio offers. The RSGB Scouts, Cadets and Girlguiding Youth Champion, Samuel McCutchion, 2E1UEL, recently completed the Radio Surfer Award and shared his experience with us. Read how he got on by going to rsgb.org/award-stories  At a recent meeting of the RSGB Regional Forum, the RSGB Regional Representatives elected George Crawford, MM0JNL, as the Regional Forum Chair. George represents Scotland South and Western Isles as the Representative for Region 1. He got involved in amateur radio in 2020 and gained his Full licence by March 2021. George has also been a GB2RS Newsreader. Along with the rest of the Regional Team, George is keen to continue to help RSGB members and the wider amateur radio community, and to promote amateur radio and the Society at public events. He will be attending Kirriemuir Show on the 19th of July to showcase amateur radio to the agricultural and rural communities. You can hear more details about that in the Special Event News section of this week's GB2RS News. Last week, senior RSGB staff and some members of the RSGB Board met for two days to discuss the next implementation phase of the Society's strategy. The discussions covered several topics, including how to ensure the Society stays relevant to the modern radio amateur. Those discussions led to some initial plans for the next six months that focus on one or two clear goals. More details of the plans will be shared over the coming weeks, including in strategy updates and at the ‘Meet the Board' session at the RSGB Convention in October. Following the RSGB's attendance at Dayton and Friedrichshafen, it was also noted that the Society is held in high esteem around the world and that many other national societies are keen to learn from the RSGB's achievements. Ben, M7FRS and John, G0JDL, are hoping to be operating aeronautical mobile in a Cessna 172 for about an hour tomorrow, Monday the 14th, over the skies of Norfolk and Suffolk. The pair will be departing from Beccles Airfield at around midday. They will initially be on the 2m band FM calling frequency of 145.500MHz before changing frequency. As per the new licensing arrangements, they will be using less than 500mW. Listen out for them, as they'd love to get you in their log!  During this weekend's IARU HF World Championship, five stations will be active on the 80 to 10m bands using SSB and CW and tested under field conditions. They will be using the exact planned equipment for the WRTC 2026 event as a trial. The operating location will be a cluster of sites within the grounds of the Euston Estate in Suffolk. QSL via M0OXO's OQRS. There will be two awards available for chasers during this event, so listen out for the following callsigns: GB0WR, GB2WR, GB5WR, GB8WR and GB9WR.

Now the contest news The IARU HF Championship started at 1200 UTC on Saturday, the 12th and ends at 1200 UTC today, Sunday, the 13th of July. Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and ITU Zone. The UK is in Zone 27. The GR2HQ Challenge also started at 1200 UTC on Saturday, the 12th and ends at 1200 UTC today, Sunday, the 13th of July. Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and ITU Zone. The UK is in Zone 27. Today, the 13th, the UK Microwave Group 24, 47, and 76GHz Contest runs from 0900 to 1700 UTC. Using all modes on 24 to 76GHz frequencies, the exchange is signal report, serial number and locator. On Tuesday the 15th, the RSGB 1.3GHz UK Activity Contest runs from 1900 to 2130 UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator. On Wednesday the 16th, the RSGB 80m SSB Club Championship runs from 1900 to 2030UTC. Using SSB on the 80m band, the exchange is signal report and serial number. On Thursday the 17th, the RSGB 70MHz UK Activity Contest runs from 1900 to 2130 UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. On Saturday the 19th, the RSGB 70MHz Trophy Contest runs from 1400 to 2000 UTC.

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

Ein Standpunkt von Felix Feistel.Seit etwa 2020, parallel zu einer nicht existenten Coronapandemie, wird das 5G-Netzwerk massiv ausgebaut. So ist Deutschland mittlerweile fast flächendeckend mit dem neuen Netz abgedeckt. (1) Beworben (2) wird 5G mit den überlegenen Fähigkeiten gegenüber 4G. So könne 5G zehnmal so viele Daten pro Sekunde übermitteln und auf einem Quadratkilometer bis zu eine Millionen Geräte verbinden. Damit ist 5G die wesentliche Voraussetzung für das Internet der Dinge (IoT), sowie für das autonome Fahren (3), beides Technologien, die derzeit von finanzstarken Konzernen vorangetrieben werden.Dabei nutzt 5G nicht nur alle Frequenzen zwischen 700 MHz und 2,6 GHz, die schon von den bisherigen Mobilfunkstandards genutzt werden, sondern darüber hinaus Frequenzen bis 3,8 GHz. Für manche Anwendungsmöglichkeiten werden zudem Hochfrequenzen im sogenannten Millimeterbereich zwischen 24 und 27,5 GHz benötigt. Diese Frequenzen zeichnen sich durch sehr kurze Wellenlängen von wenigen Millimetern aus. (4)Während die technischen Vorteile der neuen Technologie stark hervorgehoben werden hört man wenig über die Auswirkungen auf die Umwelt und die menschliche Gesundheit dieser Frequenzen. Diese scheinen im Angesicht des technischen Fortschrittes von untergeordneter Bedeutung zu sein. Dabei stufte die WHO den Mobilfunk bereits im Jahr 2011 als„potenziell krebserregend“ (5)ein. In Bezug auf 5G stellt die WHO dann allerdings lapidar fest, dass bislang keine gesundheitlichen Risiken durch elektromagnetische Strahlung festgestellt werden konnten, erklärt dabei aber auch, dass bislang kaum Studien durchgeführt wurden. (6) Zu ähnlichen Ergebnisse kommt das deutsche Bundesamt für Strahlenschutz (BfS).Die WHO stützt sich bei ihrer Einstufung der Risiken durch Mobilfunkstrahlung im Wesentlichen auf die Ergebnisse der Internationalen Kommission für den Schutz vor nicht-ionisierender Strahlung (ICNIRP) (7). Dabei handelt es sich um eine deutsche Organisation, die teilweise aus öffentlichen Geldern finanziert wird und in räumlicher Nähe zum Bundesamt für Strahlenschutz untergebracht ist. (8) Sie legt international die Richt- und Grenzwerte, etwa die Spezifische Absorptionsrate, den sogenannten SAR-Wert, fest. Dieser beträgt bei modernen Geräten zwischen 0,10 und 1,99 W/g. Dabei gilt: Je höher der SAR-Wert, desto größer der erwärmende Effekt auf Gewebe. (9)Die ICNIRP geht bei ihren Risikobewertungen jedoch sehr selektiv vor. So hat sie in einer 2018 veröffentlichten Richtlinie zu gesundheitlichen Auswirkungen von elektromagnetischen Frequenzen die 2011 von der WHO getroffene Einschätzung als „potenziell krebserregend“ beispielsweise gar nicht mit aufgenommen.

Paul Wright “We're covering 28 square miles with the same cost it takes to dig one mile of fiber—and we're doing it with gigabit speeds.” — Paul Wright, Chief Revenue Officer, CBNG In a timely conversation on Technology Reseller News, Publisher Doug Green interviews Paul Wright, Chief Revenue Officer of Cambridge Broadband Networks Group (CBNG), to examine a growing concern: fiber broadband rollouts in the U.S. are failing to meet demand, especially in rural and hard-to-reach communities. Wright proposes a viable, scalable alternative—Fixed Wireless Access (FWA)—driven by 5G and CBNG's next-generation point-to-multipoint microwave radios. CBNG, with a legacy of delivering carrier-grade radio equipment since 2000 and over 350,000 radios shipped globally, is launching a new 5G NR platform that delivers up to 5 Gbps. Wright illustrates how the economics of FWA are revolutionizing broadband planning: for the same cost of trenching one mile of fiber (about $40,000), CBNG's solution can cover 28 square miles with high-speed wireless internet. Wright explains how FWA uses licensed spectrum and advanced 5G technologies—like beamforming and standalone operation—making it ideal for quick deployments. With BEAD funding recently liberalized to allow alternatives to fiber, CBNG's timing is critical. “Now it's about cost and speed of delivery,” Wright notes, “and FWA is winning on both counts.” The setup is simple: a small antenna on a home or business connects to a hub station, and installation takes under an hour. Wright envisions municipalities, entrepreneurs, and WISPs driving connectivity forward without waiting on major carriers. While fiber has its place—especially in greenfield builds—Wright emphasizes that FWA is no longer just a stopgap. “It's a practical long-term solution,” he says, “especially when fiber may never come.” CBNG's 5G NR solution operates in the 39 GHz band, with upcoming support for 24–30 GHz. It's designed for ease of use and fast ROI, especially for those holding licensed spectrum. Learn more: https://www.cbng.co.uk

IEEE 802.11ax Wi-Fi 6 and 6E represent major advancements in wireless technology, particularly for industrial environments, due to their incremental efficiency, scalability, and bandwidth. Key features like OFDMA allow multiple devices to communicate simultaneously on subdivided channels, reducing latency and improving spectrum use. Wi-Fi 6E introduces the 6 GHz band, significantly expanding available bandwidth and alleviating congestion. While private cellular network alternatives are increasingly popular, they are often more expensive and complex to implement. Wi-Fi 6E provides a cost-effective, reliable alternative that supports digital transformation initiatives like Phoenix Contact's Digital Factory Now, enabling efficient data transport for AI, digital transformation, and automation.Learn more about the Innovative benefits of Wi-Fi 6 and 6E in Industry in this informative podcast.Additional Resources are available at:Industrial WLAN with Wi-Fi 6 | Phoenix ContactIndustrial and Outdoor Wireless LAN Market Size Forecast | ARC Advisory GroupAlso feel free to reach out If you have any questions or would like further information about industrial Wi-Fi:Danny Walters, Product Marketing Specialist for Wireless Products, Phoenix Contact USADanny Walters | LinkedIndwalters@phoenixcontact.comChantal Polsonetti, Vice President Industrial Network Infrastructure & Industrial Edge, ARC Advisory GroupChantal Polsonetti | LinkedIncpolsonetti@arcweb.comIndustrial WLAN with Wi-Fi 6 | Phoenix ContactWireless LAN – the standard for wireless Ethernet.

This week's EYE ON NPI is a super connector - it's the Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) with 2.4GHz and 5GHz WiFi 6 support, plus optional Bluetooth LE, in a low cost co-processor you can add to any microcontroller project you have to instantly IoT-ify it. This family of chips is a big upgrade in the CC3 family, and looks like a very competitive solution to existing market chips - we're excited to see how TI has adapted to the existing market to bring this compelling offering. Oh the TI CC3x series, how you've grown! We first met you back when it was the CC3000, a radical WiFi co-processor with the (at-the-time) astonishing price of ~$10 per module. At the time, we crafted an Arduino-compatible shield and a breakout board (https://learn.adafruit.com/adafruit-cc3000-wifi/overview) as well as an Arduino port of the TCP/IP mini-stack so that folks could do amazing things like get the time (https://learn.adafruit.com/adafruit-cc3000-wifi/internettime), read a web page (https://learn.adafruit.com/adafruit-cc3000-wifi/webclient) or even send a Tweet (https://learn.adafruit.com/adafruit-cc3000-wifi/sendtweet). The big thing was making it so you weren't spending the $50 it cost up-till-then to add a full-linux-system-as-peripheral (https://www.adafruit.com/product/1498). Since then, TI has released some updated versions, such as the CC3100 (https://www.digikey.com/short/9cp431pr), which added 802.11n and lower power draw - we saw it featured in a few micropython projects (https://blog.adafruit.com/2016/08/24/micropython-name-badge-from-emf-2016/) thanks to the core driver support (https://github.com/micropython/micropython/tree/master/drivers/cc3100). And after that, the CC3200 series (https://www.digikey.com/short/9289jcq3), which added TLS/SSL support and had an internal ARM Cortex-M4 that could run code on its own, like MicroPython! (https://github.com/micropython/micropython/blob/master/ports/cc3200/README.md) So it's no surprise that TI is continuing to press their WiFi family forward, to now the CC33xx! The new Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) comes with 4 variants: the CC330x have 2.4GHz WiFi only, where-as the CC335x add 5GHz for an additional cost. Likewise, the CC33x0 have only WiFi, and the CC33x1 have WiFi+BLE. Since all the chips / modules are pin-compatible, you can develop with one and then change in production to whatever final setup suits your product. Like the earlier chips, these chips are expected to be connected to a main processor: either a microcontroller or microcomputer, over SPI or SDIO. SPI will work great for your smaller micros, SDIO is great when you have the speed and bandwidth to shift a lot more data around. When connecting over BLE, use the UART-with-flow control - that's the standard for a "BTLE Host Controller Interface" communications (https://www.bluetooth.com/wp-content/uploads/Files/Specification/HTML/Core-60/out/en/host-controller-interface/uart-transport-layer.html). Of course, there's no way you'll want to write a driver for this kind of complex chip - so visit the CC33xx software download page (https://www.ti.com/tool/CC33XX-SOFTWARE) which has software in the form of Linux kernel patch/drivers for beefy chips, or an microcontroller with an RTOS - follow their porting guide to get it running on a non-TI chipset (https://dev.ti.com/tirex/explore/node?node=A__AEIJm0rwIeU.2P1OBWwlaA__CC33XX-RTOS-MCU__dzPVh4K__LATEST) Now you're probably saying "OK cool but I don't want to do a bunch of RF layout, I want a nice tinned module i can slap down and connect my RP-SMA or chip antenna" - and not surprisingly, it looks like there's a CC3301 module (https://www.ti.com/product/CC3301MOD) in pre-production with an optimistic budgetary price of $2.88 - that's for 2.4GHz + BLE. For the 5GHz CC3351MOD (https://www.ti.com/product/CC3351MOD) the price is $3.50. Sans BLE the CC3350MOD (https://www.ti.com/product/CC3350MOD) is $3.13.

This initiative is part of the ongoing Khafre Research Project, which utilizes advanced satellite technology to explore the site's concealed architecture.​Key Discoveries:Subsurface Structures: The SAR scan revealed five small, room-like structures within the Khafre Pyramid, centrally located above the chamber known as the "Belzoni Chamber," which contains a sarcophagus previously misidentified as the pharaoh's tomb. ​Vertical Shafts: The team identified eight large vertical structures, possibly wells or shafts, extending over 6,500 feet across and reaching depths of approximately 2,000 feet beneath the pyramid. ​Vast Underground Complex: The findings suggest the presence of a substantial subterranean network beneath the Giza Plateau, potentially corresponding to the legendary "Halls of Amenti" described in ancient Egyptian mythology. ​Methodology:The team employed Synthetic Aperture Radar (SAR) technology, utilizing X-band microwaves (10 GHz, 3 cm wavelength) to detect subtle surface vibrations caused by deep underground voids. This non-invasive technique allowed the researchers to infer the presence of hidden structures without physical excavation. Skepticism and Expert Opinions:Despite the groundbreaking nature of these findings, some experts have expressed skepticism:​Professor Lawrence Conyers, a radar expert at the University of Denver, questioned the technology's capability to penetrate the dense limestone of the pyramids to such depths, suggesting that the idea of an underground city is "a huge exaggeration." ​Conclusion:The Khafre Research Project's findings have sparked both intrigue and controversy within the archaeological community.

Les horloges atomiques sont les instruments de mesure du temps les plus précis au monde. Elles permettent de définir la seconde avec une précision extrême et jouent un rôle clé dans des technologies comme le GPS et les communications. Mais comment fonctionnent-elles exactement ?La base du temps : les atomesContrairement aux horloges classiques qui utilisent des ressorts ou des pendules, les horloges atomiques mesurent le temps grâce aux propriétés des atomes. Plus précisément, elles exploitent la fréquence des oscillations des électrons lorsqu'ils changent d'énergie à l'intérieur d'un atome.L'atome le plus couramment utilisé est le césium-133. Lorsqu'il est soumis à des ondes électromagnétiques, ses électrons peuvent passer d'un état d'énergie à un autre en oscillant à une fréquence extrêmement stable : environ 9 192 631 770 oscillations par seconde. Cette fréquence est utilisée pour définir la seconde.Un processus précis de mesure1. Vapeur d'atomes de césiumOn commence par chauffer un échantillon de césium pour en extraire des atomes sous forme de vapeur.2. Sélection et excitationLes atomes passent ensuite dans un champ magnétique qui sélectionne uniquement ceux dans le bon état d'énergie. Ils sont ensuite exposés à des ondes micro-ondes à une fréquence proche de 9,19 GHz.3. Résonance parfaiteSi la fréquence des micro-ondes est parfaitement ajustée, un maximum d'atomes change d'état d'énergie.4. Détection et ajustementUn détecteur mesure combien d'atomes ont changé d'état. Si le nombre est maximal, cela signifie que la fréquence des micro-ondes est correcte. Sinon, elle est ajustée pour atteindre la valeur exacte.Une précision inégaléeGrâce à ce processus, les horloges atomiques modernes peuvent atteindre une précision telle qu'elles ne retarderaient que d'une seconde tous les 30 millions d'années ! Les modèles les plus avancés, utilisant des atomes de strontium ou d'ytterbium, sont encore plus précis.Applications des horloges atomiquesElles sont essentielles pour :- Le GPS : les satellites utilisent des horloges atomiques pour synchroniser les signaux et permettre une localisation ultra-précise.- Les télécommunications : elles garantissent la synchronisation des réseaux.- La physique : elles aident à tester des théories fondamentales comme la relativité d'Einstein.En résumé, une horloge atomique utilise les vibrations ultra-régulières des atomes pour mesurer le temps avec une précision inégalée, révolutionnant ainsi notre manière de compter les secondes !

New cellular network deployments are often associated with new frequency bands. 6G will likely use the upper mid-band from 7-24 GHz. It is called the “golden band” since it provides more spectrum than in current 5G networks and features decent propagation conditions. In this episode, Erik G. Larsson and Emil Björnson discuss the coexistence issues that must be overcome when operating in this band and how much spectrum we can expect to utilize. The future role of multi-antenna technology and its associated challenges are detailed, including the emerging “Gigantic MIMO” term. The prospects of exploiting near-field propagation effects in 6G and the road towards distributed cell-free MIMO are also covered. You can read Emil's paper about Gigantic MIMO here: https://arxiv.org/pdf/2407.05630 Nokia has a white paper about coverage evaluation: https://onestore.nokia.com/asset/213702 Music: On the Verge by Joseph McDade.
