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

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

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

GB2RS News Sunday, the 26th of October 2025 The news headlines: Get involved with YOTA Month and book your GB25YOTA operating slot today Photos from the VHF and HF contest trophies presentation are now on the RSGB website RSGB gives an update on the QSL Bureau Youngsters on the Air Month takes place in December, and the RSGB would love you to take part in this annual event. Special callsign GB25YOTA will be active throughout the month. Whether you are an individual, club, school, university or social group, this is a fantastic opportunity to host the callsign and get young radio amateurs active on the amateur bands. The Society would love to see Scouts, Girlguiding and Cadet groups taking part too. The RGSB has changed the procedure for booking operating slots this year, so it is easier to see availability. Visit rsgb.org/yota-month and click on the schedule to view which time slots are available. These aren't fixed and can be adjusted to suit your timings. You'll then need to email RSGB YOTA Month Coordinator Jamie, M0SDV via yota.month@rsgb.org.uk to register as a GB25YOTA host and book your slot. Jamie can also help with any questions about taking part for the first time. The Society is aiming for the callsign to be hosted every day during December to enable more youngsters to have a taste of amateur radio. Be part of this great goal and book your operating slot today. The main VHF and HF contest trophy presentations were held at the RSGB 2025 Convention on Sunday, the 12th of October. A list of the winners and photos from the presentation can now be seen on the RSGB website via rsgb.org/trophies and selecting ‘Awards photos galleries' from the menu on the right-hand side. During the presentation, the prestigious ROTAB Trophy was awarded to John Warburton, G4IRN, for outstanding and consistent DX work. The RSGB would like to congratulate John and all the winners who received a trophy. Following the well-deserved retirement of QSL Bureau Manager Richard Constantine, G3UGF, the RSGB Board is making arrangements to ensure the continued smooth operation of the QSL Bureau service. Members should continue to send outgoing QSL cards to PO Box 5, Halifax, as usual. Similarly, incoming cards will continue to be distributed by your existing sub-manager, and stamped, addressed envelopes should still be sent directly to them. The Board is currently finalising new management arrangements for the Bureau and will provide a further update once these are in place. The Board wishes to record its sincere thanks to Richard for his many years of dedicated service to the Society and to the amateur radio community. Following Ofcom's recent implementation of Phases 2 and 3 of the amateur radio licence review, it has updated its main guidance document. Please ensure you use the October 2025 edition so that you are using the latest information. Ofcom has also clarified that if you hold a Special Contest Callsign NoV and you change your individual or club callsign, the SCC NoV is still valid. This is because your Full Amateur Radio Licence reference number has not changed. If you do hold an SCC NoV and you have changed your individual or club callsign, please send an email to scc@rsgb.org.uk  stating your old callsign, your new callsign and your SCC, so the RSGB Contest Support Committee Chair can update the issued SCC list.

It looks like Earth dodged a bullet last week when a large coronal mass ejection, or CME, erupted on the far side of the Sun on Tuesday, the 21st of October. Had that CME been Earth-directed, we could have endured a strong, or possibly an extreme, geomagnetic storm with dazzling displays of aurora. The source of the eruption was possibly sunspot region 4246, which is now past the Sun's west limb. The ACE spacecraft detected high levels of protons streaming past Earth, but they remained below the minor S1 radiation storm threshold. In other news, we have had a quiet geomagnetic week, which has allowed the ionosphere to shine. The solar flux index has been modest, ranging from 130 to 150, but propagation has been aided by improved geomagnetic conditions. During the past week, the 10m band was humming with activity. Lots of stations were preparing for the CQ World Wide SSB Contest, which ends today, the 26th. 8P5A in Barbados has been romping in during the afternoon, as has HZ0YL in Saudi Arabia. Other DX worked last week, according to the CDXC Slack chat group, includes VK9DX on Norfolk Island on 12m SSB; 6O3T in Somalia on 40m CW; and PJ6Y on Saba and St Eustatius using SSB on the 12m band. This last station is a young radio amateurs' DXpedition by the Pacific Island DX Group. Next week, NOAA predicts that the solar flux index will stay in the 140 to 150 range with the Kp index starting the week low but then rising. We may expect a Kp index of 5, or even 6, around the 28th to the 31st of October. Look for auroral conditions and lower maximum usable frequencies during this period. Meanwhile, make the most of the long-range propagation on the higher bands while the Kp index is low. And now the VHF and up propagation news from G3YLA and G4BAO The period of weather up to the end of the week ending the 2nd of November looks distinctly unsettled, with the weather pattern driven by an Atlantic jet stream pointing straight at the British Isles. This will mean that further periods of stormy weather are possible with strong winds and heavy rain. This is not a time to expect much tropo for VHF or UHF, but it is a good period for the GHz bands to explore rain scatter propagation. The foF2 and foEs graphs at propquest.co.uk  have been experiencing some data supply issues recently. It's worth noting that strong jet streams and fast-moving weather systems, as we have now, can bring a chance of out-of-season Sporadic-E. A good example on the evening of Sunday, the 19th of October, can be found if you check the archive tab. This four-hour active period was possibly associated with a slowly advancing jet stream as seen on the Sporadic-E blog tab for that date. Meteor scatter operators had the Orionids, which peaked on the 22nd, to play with last week. The broad zone of activity may continue to provide weakening interest through the coming week. The Kp index has been relatively subdued recently, but the message is once again to continue to monitor for the chance openings by noting when the Kp index reaches 5 or more, or if you start to hear LF CW signals take on a fluttery note. For EME operators, the Moon's declination is at a minimum today, the 26th, so Moon window lengths and peak elevation are both low. Apogee was early on Friday the 24th, so path losses are falling again. 144MHz sky noise rises over the weekend, reaching some 3300K today, the 26th, before falling steadily to low levels the following Friday. And that's all from the propagation team this week.

In today's episode, we sit down with Dean Bubley, Tech Industry Analyst and Futurist with Disruptive Analysis, to discuss the ongoing conversation over the 6 GHz spectrum. Dean breaks down the politics, policy, and potential of 6 GHz, and we discuss why the band is essential for home, enterprise, and industrial Wi-Fi. We also examine the misconceptions around the “5G and 6G race,” and Dean explains how solutions like dynamic spectrum sharing could offer a better path forward. Tune in to discover how preserving the 6 GHz band for Wi-Fi could shape the future of global connectivity.Dean Bubley: After Budget Bill, Do No Harm to CBRS and 6 GHzFor Wi-Fi AllianceFor Membership InfoGeneral Contact

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

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

GB2RS News Sunday, the 19th of October 2025 The news headlines: · Ofcom implements Phases 2 and 3 of the amateur radio licence review · Share your feedback on the RSGB's 2025 Convention · The RSGB releases a video to help members make the most of its mobile app Following the introduction of the current amateur licensing framework in February 2024, Ofcom has now implemented most of the remaining changes associated with Phases 2 and 3. Ofcom updates its online Licensing Portal to accommodate applications for new M8 and M9 Intermediate callsigns, more flexible special event callsigns, and other changes, including easier revalidation. It also starts a gradual move to single personal call signs. For example, the revocation of lower licence callsigns is automatically triggered by a new application. Both Ofcom and the RSGB have released guidance for radio amateurs about these changes. You can see both documents by going to rsgb.org/guidance-resources. Please also note that the Ofcom licensing portal now requires longer and stronger passwords, so you may need to reset yours first before you can make any changes.

The Worked All Germany Contest started at 1500 UTC yesterday, the 18th, and ends at 1500 UTC today, the 19th of October. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. The CQ World Wide DX SSB Contest starts at 0000UTC on Saturday, the 25th and runs until 2359 UTC on Sunday, the 26th of October. Using SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 16th of October Conditions over the past week have been reasonable with a relatively high solar flux and lower Kp indices. This resulted in a maximum usable frequency, or MUF, over a 3,000km path, in excess of 35MHz. This is just what October was meant to be like! But all good things come to an end and there are a few flies in the ointment coming up. On the 14th, the latest coronal mass ejection, or CME, tracking model from NOAA and the Space Weather Prediction Testbed showed three weak CMEs possibly passing Earth over the next few days.  Although none of them is expected to deliver a large impact to the Earth's geomagnetic field, a combined passage could generate minor G1 to isolated moderate G2 geomagnetic storming.  We are now well and truly into autumn and, with a daytime critical frequency of more than 9 to 10MHz, the 40m band is ideal for QSOs around the UK during the daylight hours. At night, the critical frequency is generally around 5MHz in the early part of the evening, dropping to 3.5 to 3.6MHz as the night progresses. This means that the 80m band is remaining open around the UK for longer, but it may fade out, perhaps towards midnight. October is a great month for HF with the potential for worldwide openings on the higher bands. Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range. Unsettled geomagnetic conditions with reduced MUFs are forecast for the 20th of October and then again on the 25th and 26th, when the Kp index could hit 5. Incidentally, these are the same dates as the CQ Worldwide SSB contest. And now the VHF and up propagation news from G3YLA and G4BAO This next period offers a marked contrast to our recent spell of Tropo weather under high pressure. Today, the 19th, sees a change to a much more unsettled weather type with rain, areas of low pressure, strong winds and showers. This will take Tropo off the agenda for the coming week, and its replacement is likely to be rain scatter for those on the GHz bands. There is no point in trying to time each individual low and front coming through this far ahead, and there is no real scope for any significant intervening areas of high pressure between the lows. So, there is no hint of Tropo next week. The recent solar conditions have again suggested that it's worth looking at the Kp index for signs of aurora, should it go above 5. Next, a few words about meteor scatter, which is gearing up for the Orionids, peaking on Tuesday, the 21st. However, they can have a broad spread with a minor peak preceding the main event. Either way, it's worth checking up on meteor scatter techniques and frequencies before the shower, rather than wondering what to do when it happens. For EME operators, the Moon's declination is falling again and becomes negative today, the 19th, so Moon window lengths and peak elevation follow suit by falling. Path losses are still rising as we approach apogee early on the morning of the 24th.  As we move through 2026, we reach a ‘sweet spot' in June where perigee and the highest declination coincide. This means the lowest path losses occur when we have the longest Moon windows. This cyclic event last occurred in 2018 and will not occur again until 2035.  144MHz sky noise starts the week low until Tuesday, the 21st, when the Sun and Moon are close in the sky. This brings noise problems for Yagi-type antennas with their high beam width. After that, the noise rises too high again for the weekend beginning the 25th of October. And that's all from the propagation team this week.

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

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 2nd of October 2025 Last week was characterised by very unsettled geomagnetic conditions with a Kp index that reached 7.33 on the 30th of September and was often above 5. This is not good for HF propagation! But what caused this? A high-speed solar wind stream at around 750 kilometres per second, coupled with the Bz component of the Sun's magnetic field pointing south, led to the disruption. But there didn't seem to be any particular solar event that triggered the high-speed solar wind stream. The Russell-McPherron effect is probably to blame. This is a phenomenon where the alignment of the Earth's and the Sun's magnetic fields, during the equinoxes around March and September, allows charged particles from the solar wind to more easily penetrate the Earth's magnetosphere. This enhanced connection leads to more intense geomagnetic storms and increased aurora activity as the Bz aligns favourably with the Earth's magnetic field at these times. This may pass as we get further into October. As a result of the geomagnetic storm, maximum usable frequencies, or MUFs, have often been lower than normal. A quick listen on 28MHz on Wednesday, the 1st of October, confirmed the poor conditions. It's a shame, as October is normally a fantastic month for HF DX. The solar flux index peaked at 187 on the 30th of September, having been above 170 since the 28th of September. Next week, NOAA predicts that the solar flux index will remain above 150 to 160 all week. The good news is that geomagnetic conditions are forecast to improve, with a maximum Kp index of 3. If that comes to pass, we can expect HF to be better after a day or two, and we might be able to make the most of the autumnal conditions for DX. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of unsettled weather, mainly over northern areas, is typical of the season, but it's also common to find high pressure passing by in between the deeper lows. In the current pattern, the highs are mainly for the southern half of Britain. This will bring some good Tropo conditions at times for the VHF and UHF bands.  As we head into autumn, these lifts may linger through much of the morning on some days before the temperature rise breaks down any temperature inversion. A good clue is that it's usually over when the overnight fog clears. On the other hand, there will probably be some good rain scatter opportunities on the GHz bands as the active lows push fronts across the country, especially in the north. There are signs that we may return to high pressure over the country during the RSGB 2025 Convention weekend from the 10th to the 12th of October. We have a meteor shower to play with during the coming week. The Draconids peak on Wednesday, the 8th of October, but the shower stream is spread over the whole of the week. Lastly, there have been some reasonable auroral events recently, so, as usual, keep a watch on the Kp index going over 5 since, as we said earlier, these autumn months are very much favoured for auroral activity. For EME operators, the Moon's declination is increasing and goes positive tomorrow, the 6th, so lengthening Moon windows and increasing peak elevation is the story for the coming week. Path losses continue to fall as we approach perigee on the 8th of October. 144MHz sky noise will be low for much of the next seven days. And that's all from the propagation team this week.

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.

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.

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.

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.

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

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. If you want a peek at what the CC3301 module might look like, the BoosterPack product page has a tantalizing glimpse (https://www.ti.com/tool/BP-CC3301MOD). You can sign up at TI's site for updates on the release schedule, or chat with your DigiKey sales rep and they'll let you know when the part makes it into general distribution. Until then, you can get plenty of TI CC3350 (https://www.digikey.com/short/3z7tqtrp) and CC3351 (https://www.digikey.com/short/hmqzwv5j) bare chips: they're both in stock at DigiKey for immediate shipment! Order today and you'll quickly add low-cost WiFi 6 + BLE support to your next design, with 2.4/5 GHz support so you're ready for any customer or configuration. With ready-to-go software, and great low prices, you can get your design set up with cutting-edge networking without breaking the BOM bank.

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.
