Foundations of Amateur Radio On your amateur radio journey, you'll likely discover that many transceivers run on 13.8 volt DC, give or take. For example my FT-857d requires 13.8 volt plus or minus 15 percent, with a negative ground, and a current draw of 22 ampere, more on that later. In other words, the power supply needs to be between about 11.7 and 15.9 volts, the same voltage that runs most vehicles with some wiggle room for fluctuating alternator charging cycles. While some radios will absolutely fit in your car, there's plenty where that just isn't the case, even though they're set-up for a 13.8 volt power supply. You might think of it as an anachronism, a few steps removed from spark gap transmitters, but there's more to the story. Most residential power grids run on AC power, at varying voltages and frequencies between 50 and 60 Hz. Across the world there's eight different AC voltages in use between 100 and 240 volts. Some countries use more than one combination and I haven't even looked at three phase power. Perhaps 13.8 volt DC isn't looking quite as odd. With this revelation comes the need to actually have 13.8 volt available in your shack. Converting your grid power to something you can plug your gear into requires some form of transformation, typically achieved with a power supply. Efficient, cheap and plentiful, the switch mode power supply is the most common. Built to a price, they're also often noisy, not just the fan, but noisy from a radio emissions perspective. Amateur radio has very sensitive receivers and as a result you can often hear, or see if you have a waterfall display, RF birdies, a sound reminiscent of a budgie whistling, every 100 kHz or so across the whole radio spectrum. Not something most other equipment cares about, so you're often left to fend for yourself in figuring out how to deal with this phenomenon. There's plenty of filtering techniques and circuits to be found and some of them even work, but for my money, I'd spend it on a power supply that doesn't make noise in the first place. A regulated power supply maintains a constant output voltage or current, regardless of variations in load or input voltage. An unregulated power supply can wander all over the place. Adjustable power supplies allow you to set the voltage, amperage, or both, sometimes with knobs, sometimes using external controls. At this point you might decide that this is all too hard and you want to do away with all this complexity and use a Sealed Lead Acid, or SLA battery, after all, that's what the 13.8 volt is based on, but then you'll need to charge it. Similarly, picking any battery technology requires some form of charging. Another word for charger is: power supply, often a switch mode one, and likely not filtered in any way that matters to you, since batteries, and for that matter solar power inverters, are unlikely to care about RF birdies. I will make mention of linear power supplies. When I started on this journey, this was the strong recommendation from my peers as the most desirable option. Although they're significantly less efficient than switch mode power supplies, only 30 percent versus better than 80 percent, from an RF perspective, they're extremely quiet. Of course, the lack of efficiency reveals itself in the form of heat, which necessitates the application of cooling, from a fan, often a very noisy fan. One potential source of power supply is a computer power supply unit or PSU. Before you go down that route, consider that they're intended for installation inside a case, often generate various voltages at very specific current draws and are not typically known for being RF quiet. After weighing up all the variables, I chose a laboratory grade switch mode current limiting adjustable power supply. It's set to 13.8 volt and it sits on my desk doing its thing. Rated at 1 to 15 volts at 40 ampere, it's now as old as I am in amateur radio terms, well and truly a teenager, it's also overkill, by quite a margin. Remember when I mentioned that my FT-857d is rated at drawing 22 ampere? As a QRP or low power station I typically use my transmitter set to 5 watt, but even when others use it at full power, I have never ever seen it draw more than 12 ampere. That's not to say that it can't draw 22, I've just never seen it. As a benefit of having such a massive overkill in the specifications of my power supply, I can power more than one radio and not notice. Not that they're all transmitting at the same time, or using more than 5 watt, it just doesn't matter. I previously discussed setting a standard for coax connectors in the shack, the same is true for deciding what to pick for power supply connectors. In my case I chose Anderson Powerpole connectors. Pins come in 15, 30 and 45 ampere ratings, are genderless and housings are available in many different colours. When I say genderless, it means that you can join two identical connectors. Within my shack, I use the RACES or ARES Powerpole wiring standard and every single 13.8 volt connection uses it. If I get new gear that uses some other connector, I'll cut the power supply wire in half and terminate both the power supply and the cut off cable using Powerpole connectors. That way my gear will connect to my own power supply and I'll have a universal adaptor cable when I need it. Over the years I've collected an impressive array of adaptors using this method and it's helped immensely when sharing gear with other amateurs. Word of warning, make sure you get positive and negative the right way around when you join your Powerpole connectors, and make sure that you have the red and black housings the right way around too, you can thank me later. If you do this more than a few times, I'd recommend that you spend the money on a proper crimping tool. It makes the experience So. Much. Better. To avoid many of the pitfalls of interference whilst connecting power and coax to the same radio, try hard to avoid running both in parallel, or worse, joined to each other. Instead, attempt to run them in different directions and only cross at right angles if you have to. One thing to consider is the ability to switch everything off immediately. To that end I have a power switch on my desk that isolates all power to the equipment. You'll notice that I have not said anything about grounding or earthing, that's on purpose. Your laws and mine are not the same. Similarly, information you'll find online rarely, if ever, describes the jurisdiction it applies to, so, look at your own rules and implement accordingly.

Foundations of Amateur Radio When you start the process of getting your hobby off the ground, either for the first time, or after a hiatus, you might be left with the impression that the only way to "do amateur radio" is to have a shack, a place where you can set-up your gear, and connected to that gear using coax, one or more antennas. While that's a common scenario, it's not the only one at your disposal. We are after all in the game of communication and over the past few decades options have exploded. Starting closest to the traditional radio, coax and antenna, is to consider indoor antennas. There's many to choose from. You can install one in the same room as your shack, or, you can build your antennas in the roof space, either way, invisible from the outside can sometimes be a requirement. Stealth is a topic all its own, and no doubt we'll get to that another time. A word of caution. If you do have an indoor antenna and associated coax, consider your transmitter power levels, since it's likely that given the close proximity, you'll exceed emissions safety standards, or you'll cause harm to other electronic equipment in the building. QRP or low power is a good way to go if this is something you're considering. If we step away from a traditional radio, coax, antenna configuration, you can build your shack in other ways too. For example, you can use a local repeater which you might trigger from a local handheld radio. Often dismissed as being for local communications only, there are thousands of repeaters across the globe offering a variety of bands, frequencies and modes. Often you can access a local repeater that can be connected to a remote one using a bewildering array of technologies, some using the internet, some using traditional RF. You'll find repeaters on 10m, 6m, 2m, 70cm and 23cm. There's nothing stopping you making your own repeater. You don't even need to go through the effort of making it completely standalone, for example, my Yaesu FT-857d has a detachable face-plate or head, connected to the main body by a short cable. There are plenty of other radios with a similar configuration. Presumably designed for the installation in a vehicle, where the head needs to be near the driver and there's unlikely to be space for the body, you can run a longer cable from the head to the body and install it somewhere more convenient. In my case it was bolted underneath the removable floor into the boot next to the spare tyre. There's several solutions that replace the connecting cable with an internet connection. Now, that internet connection can be across the room, from inside your shack to your garage, or between your shack and a remote hill where you have permission to put up a bit of gear. In fact, the same type of setup can be used to connect to shared radios, and companies like Elecraft, Flex Radio and ICOM make specific remote heads that can operate remote radio equipment, marketed as RF decks, without needing to install and maintain computers at either end, but more often than not, this equipment is brand or model specific. Which raises another option. You can connect to remote equipment across the internet using your computer, which means that your shack might be a computer, a laptop, or a mobile phone and your gear might be in a different country. Many radio clubs have discovered that their often extensive radio shack is virtually unused during the week, and have installed remote equipment to allow you as a member to connect, sometimes as part of your membership, sometimes with an extra fee, since there are costs associated with setting this up and keeping it running. At some point you're going to discuss this with other amateurs and you're potentially going to hear someone tell you that this is not "real radio". Considering over a century of radio evolution, from spark-gap through valves, transistors, integrated circuits and software defined radio, where exactly is the "real radio" line drawn? Is using WSPR, RTTY, FT8, Hellschreiber, Olivia, SSTV, PSK31, Domino, MFSK and thousands of other digital modes "real radio"? If the answer to that is an emphatic "yes", then ask yourself, how do you actually use those modes? The answer looks suspiciously like a computer running digital mode software, either connected to a physical radio in the same room, or connected to one across the internet. In other words, with the proliferation of communication alternatives, amateur radio is evolving. No doubt it will evolve further. So, today, a perfectly viable, and some might say, modern, amateur radio shack might not actually have any traditional RF based radio gear, though perhaps a hand-held might be something to consider when you next treat yourself, not because without it you're not a real amateur, but because it opens your world to other means of communication, something which I think is perhaps even more important than building the perfect shack. In other words, you are not required to have a shack to be a radio amateur, it's just that it brings with it another dimension of engagement and activity. Speaking from personal experience, I miss my functional shack, but it's evolving, so there's that. Next time I'll take a look at antennas, stealthy or otherwise. I'm Onno VK6FLAB

En este episodio de CQ en Frecuencia arrancamos hablando de cambios. Cambio de QTH, nuevas ideas para antenas, y las dificultades reales que aparecen cuando uno se enfrenta a una ubicación distinta, con condicionantes que no siempre son fáciles de resolver. Un episodio muy pegado al día a día del radioaficionado: pensar, probar, adaptar… y tener paciencia. Pero este episodio no se queda solo en lo técnico. Como cierre, te proponemos algo especial. Un cuento de Navidad para radioaficionados, titulado “Una línea gris para una barba blanca”. Una historia que mezcla radio, escucha y un poco de magia, en la que imaginamos que Papá Noel se orienta en la noche de Nochebuena siguiendo la línea gris, ayudado por la actividad de los radioaficionados de todo el mundo. Gracias a nuestros CQ, a nuestros indicativos y a esas señales que mantenemos vivas incluso en fechas señaladas, el viaje se hace posible. Un episodio que empieza hablando de antenas y termina hablando de lo que realmente sostiene a la radioafición: las personas, la escucha… y las señales compartidas. ¿Nos apoyas para que podamos seguir haciendo este podcast?

La Onda Media se apaga. Con ella, desaparece una de las infraestructuras de comunicación más importantes, resilientes y longevas de la historia. En este episodio exploramos qué significa realmente el cierre definitivo de las emisiones de RNE en OM el 31 de diciembre de 2025, y por qué este apagado va mucho más allá de un simple cambio tecnológico. Repasamos la historia de la Onda Media en España: desde los majestuosos transmisores como el de Arganda —cuyo sonido original del NO-DO recuperamos en este episodio— hasta las últimas emisiones de Radio Madrid en AM, cuyo apagado escucharemos en directo. Analizamos qué pierde el país al abandonar esta banda: cobertura nacional con pocos transmisores, robustez ante temporales y apagones, independencia de internet y redes privadas, y un sistema de emergencia capaz de llegar donde la FM y la TDT jamás podrán. También explicamos por qué tecnologías como DRM (Digital Radio Mondiale) podían haber sido la evolución natural de la OM… pero nunca se implantaron en España ni en Europa. Además, escuchamos las explicaciones oficiales de RNE y comentamos sus implicaciones: desde la dependencia de la FM y del streaming hasta la sorprendente idea de usar la TDT para “escuchar” la radio. Y reflexionamos sobre lo que significa que, en un país sin Onda Media, los radioaficionados se conviertan —una vez más— en la red de comunicación más resiliente. Entre historia, técnica, audios originales y crítica constructiva, este episodio es un homenaje a una banda que acompañó a varias generaciones… y una reflexión sobre la oportunidad perdida de modernizarla en lugar de dejarla morir. ¿Nos apoyas para que podamos seguir haciendo este podcast?

En este episodio de CQ en Frecuencia nos acompañará Gaspar Miró, EA6AMM, coordinador global del Intruders Watch System, para descubrir cómo funciona el sistema internacional encargado de monitorizar y documentar aquellas señales que aparecen dentro de las bandas de radioaficionado sin estar autorizadas. Gaspar nos explica cómo se rastrean estas señales, qué herramientas se utilizan, qué tipo de transmisiones suelen detectarse y cómo se organiza el flujo de información entre observadores, coordinadores regionales y entidades reguladoras. Es un trabajo meticuloso, constante y silencioso que permite mantener una visión clara de lo que ocurre en el espectro. Pero también hablamos de sus límites: este sistema no tiene capacidad sancionadora, ni persigue directamente a quienes generan estas señales. Su función es identificar, registrar e informar. Y, como veremos, incluso cuando la documentación es rigurosa, actuar resulta muy complicado, especialmente en el caso de emisiones de origen militar, donde la intervención de las autoridades suele ser prácticamente inviable. Un episodio para escuchar con atención, donde descubrimos qué sucede cuando afinamos el oído y observamos todo aquello que —aunque muchas veces pasa desapercibido— nos revela una realidad fascinante del espectro radioeléctrico. ¿Nos apoyas para que podamos seguir haciendo este podcast?

Cambiar de QTH no es solo mudarse: es volver a empezar desde cero como radioaficionado. En este episodio comparto mis reflexiones, dudas y planes ante un cambio de domicilio que me obliga a mirar con nuevos ojos el tejado, las normativas y las memorias técnicas. ¿Qué pasa cuando el edificio está fuera de ordenación? ¿Podré instalar mis antenas? ¿Cómo convencer a la comunidad de vecinos? Y, sobre todo, ¿cómo mantener viva la radio cuando la burocracia y la urbanística se interponen entre nosotros y las ondas? Durante casi 20 minutos repaso las opciones, los planes A, B y C, y las soluciones de fortuna que todos, tarde o temprano, tenemos que barajar los que amamos este hobby. Una conversación íntima, técnica y muy personal sobre lo que significa seguir haciendo radio… incluso cuando el QTH cambia. Porque, al final, quien quiere hacer radio, se las ingenia. ¿Nos apoyas para que podamos seguir haciendo este podcast?

Today, we're speaking to Euan Lawson, the Editor in Chief of the BJGP, about a number of issues around editing, the future of the journal and how you can get involved with the BJGP.Here's a link to the BJGP Research and Publishing Conference: https://bjgp.org/conferenceThis transcript was generated using AI and has not been reviewed for accuracy. Please be aware it may contain errors or omissions.Speaker A00:00:00.400 - 00:00:55.980Hello and welcome to BJJP Interviews. I'm Nada Khan and I'm one of the associate editors of the bjjp. Thanks for taking the time today to listen to this podcast.In today's episode, we're speaking to Euan Lawson, who is the editor in chief of the bjjp.We're going to have a chat about a number of issues around the future of the Journal, around editorial issues and how you can get involved with the BJJP as well. So, hi, Ewan. Yeah, nice to see you. And just wanted to really start by saying thanks for joining me here today for this podcast.But yeah, thanks for joining me here today, Ewan, just to have a general chat about things going on with BJGP and your role as editor.And yeah, just a chance to catch up about some of your thoughts about issues around academic publishing and then just have a chat generally about other things that you've been thinking about as editor. So how's your week been?Speaker B00:00:57.420 - 00:02:13.730We've already had that conversation before we got here. Now we won't go there again. As you know, it's not been perhaps my ideal week.But as I'm delighted to be here and talking a little bit about what's going on with the Journal and just give a little bit of insight into how things are going, perhaps the biggest thing that we're I've recently written about the impact factor at the Journal, and perhaps the most important thing I need to say is that we don't worry too much about the impact factor.I know we do quite well on the impact factor, but I wrote an editorial which really pointed out that we are much more interested in the real world influence of the journal rather than what is quite a narrow metric about citations. We're more interested in how it affects clinical, how the journal articles affect clinical practice, how they affect policy.And we're really pushing, trying to push in that direction.And once we get into worrying about the impact factor and there are a lot of perverse kind of incentives in academia and it can sometimes result in what's known as questionable research practices and things can just slide away from the ideal a little bit.So that's perhaps one of the things that we're trying to concentrate on most in this coming months and years is just making sure that we keep our impact all about real world rather than anything else.Speaker A00:02:14.130 - 00:02:26.230Yeah, you mentioned questionable research practices and you did talk about this in your editorial or your editor's briefing, but how do you think the Journal can tackle that head on?Speaker B00:02:27.750 - 00:04:23.309I mean, it is challenging because it's.The thing about QRP questionable research practices is that there's like they're a spectrum and they go from really very minor stuff, which is like, you know, giving you, a professor in your department authorship on a paper where they really didn't do anything, to a kind of a. The far end of the spectrum where you start to creep into outright research fraud.And most researchers, and I think particularly in the primary care field though, you know, we'd always got to be. You always. One has to be careful about making assumptions,

En este episodio nos adentramos en un tema que, aunque no siempre se trata de forma directa, está muy presente en nuestras bandas: cómo se vive la radioafición desde la discapacidad. Un espacio donde las limitaciones pueden ser reales, pero nunca definitivas. ️ Participan: Alberto, EA2FIR – Nuevo radioaficionado, invidente, con toda la ilusión de sus primeros pasos en la afición. Paco, EA2FIQ – También recién estrenado con su indicativo, usuario de silla de ruedas, que comparte cómo la radio le ha abierto nuevas puertas. Miquel, EA3GZA – Con trayectoria en la radioafición e invidente, además de locutor profesional en Tarragona, aporta su visión desde la experiencia. Y Alberto, EA7LGA, con quien charlamos del papel de los límites en la radioafición. A los cuatro les planteamos tres preguntas clave: ¿Qué significa para ti la radioafición y qué papel juega en tu vida cotidiana? ¿Has encontrado alguna barrera o dificultad relacionada con tu discapacidad al practicar la radioafición, y cómo las has afrontado? ¿De qué manera la radioafición te ha ayudado a superar limitaciones, conectar con otras personas o sentirte parte de una comunidad? Sus respuestas nos ofrecen una mirada auténtica y diversa sobre cómo la radioafición es compañía, aprendizaje, apoyo y, sobre todo, comunidad. Además en este episodio Repasamos el programa de charlas de Iberradio 2025, con una agenda rica y variada que obliga a elegir entre sesiones paralelas sobre satélites, historia, concursos, diplomas, juventud, expediciones y mucho más.

GB2RS News Sunday, the 7th of September 2025 The news headlines: WRTC, QO-100 and how to have a thriving club – be part of these discussions at the RSGB Convention Listen out for special GB2RS broadcasts from the NRC as part of GB70RS celebrations The RSGB replies to the latest Ofcom 2.3GHz consultation The World Radiosport Team Championship 2026 takes place in the United Kingdom, and Mark Haynes, M0DXR, is the Chairman of the Organising Committee. Join Mark at the RSGB Convention on Saturday, the 11th of October, to find out how the team is progressing for the event, which will host 100 operators from all around the world. If operating via QO-100 is something you would like to try, join Paulo, F5VMJ/G0MUW, as he shares his experience of the mode, including his home setup and how to go portable. In a new-style presentation for this year, representatives from four amateur radio clubs will be joining a panel at the Convention. They will each discuss different aspects of their club activities that are contributing to the club's success and growth. Join the conversation, share your thoughts and experience, and be inspired. If you'd like to get practical during the Convention weekend, there are a variety of opportunities, including three workshops. The majority of workshop tickets are now sold, so book now to avoid disappointment. With only five weeks until the Society's annual Convention, secure your place via rsgb.org/convention. The RSGB Convention takes place at Kents Hill Conference Centre in Milton Keynes between the 10th and 12th of October. This year marks the 70th anniversary of the RSGB's weekly news broadcast, GB2RS. The celebrations continue with three special broadcasts scheduled from the RSGB National Radio Centre, or NRC, on Sunday, the 28th of September. Three Newsreaders will broadcast GB2RS from the NRC on the 40m band, the 2m band and via the QO-100 satellite. These readings will be in addition to those in the weekly GB2RS broadcast schedule. Special event station GB70RS will be used for pre- and post-News nets. In addition, each Newsreader will start the broadcast with a special message from the RSGB President Bob Beebe, GU4YOX. Find out timings and frequencies via rsgb.org/gb70rs  The RSGB has responded to a further Ofcom consultation, which would see new users sharing spectrum within the 2.3GHz amateur band. The latest proposals would enable a new class of short-notice outdoor deployments in the 2320 to 2340MHz range, for up to 14 days at a time. In its response, the RSGB has taken the opportunity to highlight strong concerns regarding the amateur weak signal segment at 2320MHz. This follows earlier Ofcom proposals last year for indoor use only in this frequency range. The response and background information can be found on the RSGB Spectrum Forum web pages. Go to rsgb.org/spectrum-forum  and choose the ‘Papers and consultations' tab on the right-hand side. This month is all about amateur radio and coding for the RSGB.

On Sunday the 14th, the Practical Wireless 70MHz Contest runs from 1200 to 1600 UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 3rd of September Last week's aurora may have come as a bit of a surprise! The propagation segment for GB2RS is usually written on a Thursday, but the aurora was sparked by a solar flare that took place two days later, at 2002 UTC on the 30th of August. As we don't have a crystal ball, we couldn't have predicted it! The Kp index hit 3 late on the 1st of September, with aurora visible over much of the UK. HF propagation was affected with sudden swings in the maximum usable frequency over most of the day on Tuesday, the 2nd of September. At the time of writing, a geomagnetic storm watch remains in effect with the solar wind speed above 500 kilometres per second. September is a good month for aurora due to the Russell-McPherron effect, when the Earth's axis aligns perpendicularly to the Sun-Earth line during the equinox. This creates ideal conditions for a reconnection between the solar wind and Earth's magnetic field. So, keep an eye on solarham.com for daily updates. The Sun remains active with plenty of sunspots. The solar flux index stood at 187 on Wednesday, the 3rd, down from 202 the day before. HF propagation remains good, out of the auroral periods, and as we progress into September, it should improve even more. Some of the best DX this week included VK2/SP9FIH on Lord Howe Island using the Superfox FT8 mode, and T30TTT on Western Kiribati using both CW and FT8. Other choice DX included 3C3W in Equatorial Guinea on FT8, TJ1GD in Cameroon on 20m CW, and 5H8HZ in Tanzania on 30m FT8. Next week, NOAA predicts the solar flux index will decline to 160, and then perhaps 125. Unsettled geomagnetic conditions are forecast until the 10th, with a maximum Kp index of 4 predicted. This may be due to a large elongated coronal hole on the Sun's surface, which became Earth-facing on Wednesday, the 3rd. And now the VHF and up propagation news from G3YLA and G4BAO Rain and sequences of low pressure will drive the weather agenda for much of the coming week. The only reasonable chance of Tropo appears to be Friday and Saturday with high pressure to the southeast and support for paths to the continent and across the North Sea. It is worth noting that, in general, short-lived highs like this one do not have the necessary time to generate a strong, elevated inversion before declining. So don't expect too much. Rain scatter, on the other hand, is much more likely to be worth considering for the gigahertz stations next week, with plenty of rain events coming along. The Sporadic-E season daily blogs have now finished for this year, but you may still find it worthwhile looking at the Dourbes graph at propquest.co.uk. You will notice the odd blip on the foEs trace, so keep it in mind for the 10 and 6m bands – at least for the next week. Meteor scatter is still in random territory for this period. We are between the Perseids in mid-August and the Draconids, which peak on the 8th of October. This means that the pre-dawn morning hours will be good times to try. There were some auroral signals during the 2m UK Activity Contest on Tuesday, the 2nd. We are coming into the autumn season when conditions tend to be more favourable for aurora. The message is, of course, to monitor the Kp index for values rising above 4 or 5. Remember, these three-hourly planetary readings can smooth out shorter-duration peaks, so maybe don't wait for it to get to the dizzy heights of 6 or 7 before taking an interest. Moon declination is still negative, not going positive until Monday, the 8th. So, Moon window lengths and peak elevation will continue to increase. Path losses are still falling until perigee on Wednesday, the 10th. 144MHz sky noise is low all week. And that's all from the propagation team this week.

GB2RS News Sunday the 31st of August 2025 The news headlines: Plan your RSGB Convention weekend with the newly released programme Volunteer for the RSGB as the Honorary Mature Members' Officer RSGB representatives and practical activities at the National Hamfest  Have you bought your ticket for this year's RSGB Convention yet? The weekend's draft programme has just been released, detailing all the inspiring speakers that the Society has lined up for your enjoyment. If you want to improve your technical knowledge, be sure to add the presentation by Hans Summers, G0UPL from QRP Labs, to your must-see list. Hans will introduce the concept of polar modulation SSB, along with the story of the practical implementation of polar modulation SSB in the QRP Labs QMX and QMX+ transceivers. Perhaps you'd like to get some operating tips? In which case, Walt Hudson, K4OGO, is one to add to your weekend schedule. Walt, also known as ‘Salty Walt', will discuss different types of antennas and his experience with them when operating portable. If you'd like to discover something new within amateur radio, then join Kjetil Vinorum, LB4FH, for a presentation on ‘elmering' in an online world. In addition, Mike Walker, VA3MW, will present an exclusive look at the new Aurora transceiver from FlexRadio Systems and will showcase how the Aurora pushes the boundaries of software-defined radio. With a wide-ranging programme to spark your interest, three exciting workshops, the Special Interest Groups room, GB3HQ and much more, this year's Convention is one not to be missed. The event takes place between Friday the 10th and Sunday the 12th of October at Kents Hill Conference Centre in Milton Keynes. Tickets are selling fast, so to view the full programme and book, go to rsgb.org/convention  The RSGB has announced an exciting new volunteer role, which will be tasked with attracting older people to amateur radio. The Honorary Mature Members' Officer will also be responsible for retaining and engaging with our existing senior members. The individual will research organisations or groups with memberships that include older people who may be interested in amateur radio as a hobby. They will also help to identify ways the RSGB can support lifelong enjoyment of amateur radio, including accessibility, training and social engagement. If you are an RSGB member and interested in this role, go to rsgb.org/volunteers  to read the full description. If you'd like to apply or have a chat about the role, email the Nominations Committee Chair, Will Richardson, 2E0WYA via nominations.chair@rsgb.org.uk The RSGB will have a large presence at the National Hamfest at Newark Showground on Friday, the 5th and Saturday, the 6th of September. In addition to an extensive book stall and membership stand, the Society will be running a range of exciting practical activities and demonstrations. These include a semi-interactive display of the CubeSat and a web-based dashboard from a Tiny Ground Station running remotely. There will be the opportunity to play ‘MORSE', a minimalist, wave-based strategy game operated with just two controls. You can also have your CW skills tested at a range of speeds. On Saturday, there will be an opportunity to get hands-on, building a Kanga FM receiver kit. The activities are all free of charge, and there is no need to book in advance. Members of the RSGB Board, staff and representatives from specialist committees and teams will also be in attendance and are looking forward to meeting you, answering your questions and offering support.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 28th of August 2025 This week saw a change in HF propagation with a perceptible move towards more autumnal conditions. The 10 and 12m bands have started opening up to the USA, at least on FT8. As we move into September, this will improve further. Also, as we head towards the Autumnal Equinox, we can expect better conditions on north-south paths, such as the UK to South Africa. The week saw the solar flux index climb to 226 on Thursday, the 28th, thanks to a host of sunspots, mainly in the Sun's southern hemisphere. Over the last seven days, the Sun also provided us with 12 M-class solar flares. Any associated coronal mass ejections, or CMEs, were not Earth-directed, so these had little effect, and the Kp index stayed firmly at 3 or below. The latest updates suggest that there is only a ten per cent chance of a strong X-class solar flare. FT8 continues to be the preferred HF mode, or so it seems, with stations in China, Japan, Indonesia and Cameroon making their way into UK logs on the 12m band. The 10m band has also been humming with South America rolling in during late afternoon and early evening. This can only get better as we move into September and October. NOAA predicts that the coming week will start with a solar flux index of 155 tomorrow, the 1st. This may be a little pessimistic, but we'll see. It also predicts that the solar flux index will drop off as the week progresses, ending the week at 125. Geomagnetic conditions are forecast to be good for the first half of the week, but then decline from the 4th of September. Batten down the hatches as a Kp index of 6 is forecast for the 5th, with unsettled conditions lasting until the 10th of September. Check for auroral HF signals on the 5th, or even the possibility of visible aurora from the UK. We recommend you get your HF DXing in early next week! And now the VHF and up propagation news from G3YLA and G4BAO Last week saw some lovely late-season Sporadic-E on the 6 and 4m bands, including Spain, Italy, and east into Ukraine. There was an opening to Brazil on the 24th that reached as far as East Anglia, but, as usual, stations on the south coast and west of the country had the best of the transatlantic QSOs.   This is the last bulletin in the nominal 2025 Sporadic-E season, which lasts from May to August. However, last week was a good reminder not to give up too soon, as there were several CW and SSB paths showing up, particularly on the 10 and 6m bands. There were also a few reports on the 4m band. The daily Sporadic-E blogs on propquest.co.uk  come to an end today, the 31st, but the site will continue to provide the maps as usual. To help you, notes on how to interpret the maps are available on the website. Thanks to all the Sporadic-E operators who have submitted logs to the various clusters this year. The change over to unsettled weather is now complete, and we will see rain and thunderstorms in most areas from time to time. It's a good period to check out rain scatter propagation if you are set up for the gigahertz bands. The heavier rain is well-captured by the many online rain radar displays to help you track the most active scattering volumes, which move with the stronger winds quite high up in the atmosphere. Speeds of 30 to 60 miles per hour are common. There is one note of contrast with the model evolution after midweek. One branch sticks with low pressure to the following weekend, while another outcome tries to bring in a ridge of high pressure and a chance of Tropo propagation. If the latter turns out to be the actual evolution, it may prove useful for the 144MHz Trophy and Backpackers Contest next weekend. However, it may not have arrived in time for the 144MHz UK Activity Contest on Tuesday. The solar conditions are still providing some interest for auroral propagation, but with a Kp index less than 3, nothing of use radio-wise. Look for a Kp index increase beyond 7 for that. Meteor activity is currently between major showers, so expect random activity, which suggests early mornings for checking out meteor scatter prospects. Moon declination is negative, reaching a minimum on Monda,y the 1st. So, it's a week to check out your equipment rather than to operate. With the Sun still high in the sky, it's easy to check system performance with Sun noise. Path losses started to fall after apogee on Friday the 29th. 144MHz sky noise is close to 3,000 Kelvin on Monday, dropping back to moderate on Wednesday. And that's all from the propagation team this week.

Foundations of Amateur Radio Just over a year ago, the ARRL, the American Radio Relay League, the peak body for amateur radio in the United States and one of the oldest of such organisations, experienced an incident. During the weeks following, the ARRL was tight-lipped about the extent of the incident and most amateurs only really noticed that services were off-line or slow to respond. After months of delay and disinformation, the ARRL finally revealed that it was the subject of a ransomware attack and that it had paid a million dollar ransom. It went on to blame the authorities for its silence. Mind you, it didn't tell me personally, it made public statements on its website. Similarly when I specifically contacted the ARRL to discover what information of mine it held, and what the status of that information was, the ARRL responded that I should refer to its public statements. It continued to state that my information was not compromised, since it only lived in LoTW, the Logbook of The World, the system it uses to coordinate the verification of amateur radio contacts, which are used to distribute awards like the DXCC and Worked All whatever. Imagine my surprise when I received an email this week, sent from "memberlist@arrl.org" to my non-amateur radio email address. I confirmed with several amateurs that they too received this email. Informative, to a point, but likely well beyond anything intended by its author, it stated that LoTW was being updated with associated down time, incidentally, inexplicably, coinciding with the 2025 ARRL Field day, and it "will be fully migrated to the cloud". It went on to solicit donations. It made no reference whatsoever to the ransomware attack. There's a lot hidden in that email. Although the attack last year was linked to the outage associated with LoTW, the ARRL has continued to claim that the LoTW data was not impacted by the ransomware attack, but the email reveals that the system is being migrated to the cloud, in other words, right now, it's not in the cloud. Which begs the question, where is the server infrastructure for LoTW today, and more importantly, where was it a year ago when its systems were compromised? From a public post by Dave AA6YQ, dated the 2nd of February 2021, in response to a message about a January LoTW committee meeting, we know that the LoTW server "now employs the current version of an SAP database engine". A month before that, Dave wrote another informative email that indicated that 105 thousand callsigns submitted logs to LoTW in the last 1,826 days or the five years between 2016 and 2021. There were logs from 21 thousand callsigns in the week prior to that January post. In all, according to Dave, there were 153,246 callsigns who submitted contacts to LoTW. The LoTW committee meeting minutes are no longer available from the ARRL website, but I have a copy. The document states that there were 1.2 billion contacts entered into LoTW, big number right? The next line tells us that this resulted in 262 million QSO records. I wonder what happened to the other billion records? This activity was generated by 139 thousand users using 200 thousand certificates. For context, every VK callsign automatically comes with an AX callsign, but LoTW requires that you separately register each with its own certificate. As someone who has been playing with databases since the 1980's I can tell you that LoTW is a tiny database. For comparison, the WSPR database is an order of magnitude larger, not to mention, more active. I have no insight into the business rules within the LoTW database, but the fact that updates are being processed in batches and that it regularly has delays indicates a level of complexity that I cannot account for. As an aside, the LoTW committee document lists 10 members. Dave is not one of those listed. It makes me wonder who else has access to this database. Note that I have no reason to believe that Dave's information is questionable, nor that he has access that he shouldn't, he was after all a member of the LoTW committee from 2013 until 2017 when the ARRL removed all development resources from the LoTW. I'm asking who else has access and why? While we're here, who has been doing maintenance and updates on this system over the past seven years? Moving on. The database for LoTW contains information from amateurs all over the planet, including those in Europe where the GDPR, the General Data Protection Regulation, enacted in 2016, is extremely strict on the security and disclosure of personal data with very heavy penalties for breaches. The GDPR requires notifications be sent within 72 hours of a breach, and that an organisation must designate a data protection officer. I wonder who has that role at the ARRL and I wonder if they told anyone? Did any European amateurs receive personal notification from the ARRL about their data, I know I didn't. My first activation of LoTW was in 2013, now twelve years ago. I received certificate expiry messages in 2016 and 2019. Since then there have been no such messages. That's unsurprising, since I stopped using LoTW once I discovered just how broken it was. Don't get me started on portable and QRP variants of my callsign. My care factor is low as to when I last actually used it, since attempting to dig up that information would take considerable effort, but I can guarantee that it was before 28 October 2019, when the last certificate expired. You might come to this point and ask yourself why am I digging into this at all? Let me ask you some questions in addition to those I've already mentioned. SAP, the database system which apparently runs LoTW, had 254 CVEs, or Common Vulnerabilities and Exposures listed, in 2020 alone. It continues to have exploits. When was SAP updated and is it up to date today? Is it credible that LoTW wasn't compromised during the ransomware attack? Does the ARRL know this for sure, or did it just not detect the compromise? We know that LoTW was down during the incident and according to the UptimeRobot service showed outages on the 14th of May 2024 but we still don't know exactly when this attack started. As you might know, the ARRL is also the headquarters for the IARU International Secretariat, the administration body for the global representation of our hobby. It presumably shares infrastructure with the ARRL, but at no point in the past year have we been advised of the impact of this breach to the IARU. What information is stored in LoTW and why has the ARRL continued to ignore requests for disclosing the specific information it holds on the users of that system? I know for sure that it knows my callsigns and my email address. I also know for sure that it required identity documents to prove my identity and right to use those callsigns. I have been told in writing that LoTW never deletes anything, so what does it store and can I delete all my records and if-so, how? Why did I receive an update about the upgrade for LoTW when I'm clearly not an active user of the system? The memberlist@arrl.org is used for all manner of services, including the propagation updates, and the three other ARRL bulletins. In other words, this address is used for a myriad of messaging. Is this information stored in a database and if so, where is this database? Was it compromised? What information is stored in that database? Are my details in that database, are yours? While discussing this LoTW update email with other amateurs, I was informed by one amateur that even after they stopped being a member of the ARRL, as a direct result of the ransomware attack and the discontinuation of the delivery of QST magazine they paid for, the ARRL continued to send regular email updates as-if they were still a current member. Where is that data stored and how are the ARRL not considered a source of SPAM? While we're exploring the blurred lines between being a member of the ARRL and not, why did it send the update about the incident via email to its members on 21 August 2024 and update the website a day later, and why did it not send that same email to me and every other amateur directly? Why does the ARRL continue to ignore its obligations in relation to the personal information it clearly and demonstrably holds? The GDPR has been a fact of life since 2016. It's not optional if you store data for European citizens, but the ARRL doesn't even mention it on their privacy policy page. Did European users receive specific notification about the breach, now a year ago, which clearly the ARRL had both the capacity and obligation to? Has the GDPR been invoked by European amateurs? Should it? You could attempt to explain all this as incompetence or mismanagement. That's a response, but it doesn't pass the sniff test. For example, implementing SAP is a non-trivial process. I have over 40 years professional experience in the ICT field and I'm not sure I would stick up my hand to have a go at doing this. Mind you, if I did, there's no way I'd choose SAP, I'd find an open source solution, but that's just me, not to mention that SAP license costs are significant, this in an organisation asking users for donations. The thing is, we're talking about a system that's now at least 22 years old, running in an organisation that's been around for over a century, an organisation that deals in regulation and legalese at the very foundation of its existence. In other words, there's a massive amount of legal and technical skill and history available within the organisation, but we're still seeing this level of at best questionable, at worst illegal behaviour.

SCRIPT:Amateur Radio Newsline Report 2471 for Friday, March 7th, 2025 Amateur Radio Newsline Report Number 2471 with a release date of Friday, March 7th, 2025 to follow in 5-4-3-2-1.The following is a QST. A survey reveals some important trends in Brazilian amateur radio. Huntsville's new museum of communications and technology is open -- and the founder of the Hurricane Watch Net becomes a Silent Key. All this and more as Amateur Radio Newsline Report Number 2471 comes your way right now.** BILLBOARD CART**SURVEY GIVES DETAILED SNAPSHOT OF HAM RADIO IN BRAZILPAUL/ANCHOR: Our top story takes us to Brazil where a recent survey is providing a detailed look at trends among hams in South America's largest nation. Jeremy Boot G4NJH shares some of its findings.JEREMY: An important snapshot of the state of amateur radio in Brazil has provided the national ham radio society and the telecommunications regulator with insights into relevant trends. The sampling of 940 hams in 27 states and 350 cities was conducted in May of 2024 by Guillermo Crimerius, PY2BIL, a member of the board of the Sao Paulo chapter of LABRE, the Liga de Amadores Brasileiros de Rádio Emissão. Guillermo told Newsline that the findings are also being shared with the regulator ANATEL.He said that the findings held no surprises but many details were nonetheless significant. Brazil's ham radio community remains predominantly male, with women comprising only 2 percent of the hobby. Survey results also showed that hams are an aging population in Brazil: 72% are between 40 and 70 years old, with most of them between 40 and 60. While new licensees continue to join Brazil's ham community every year, there is low membership in clubs and associations, giving little opportunity for the networking and skills training usually provided by them. Guillermo writes: [quote] "This scenario has had an impact on new generations of hams,who face difficulties in learning the essential technical matters and especially the operational and cultural activities."

Consider nominating an amateur radio operator 18 years of age or younger -- someone who has talent, promise and a commitment to the spirit of ham radio. Find application forms on our website arnewsline.org under the "YHOTY" tab. Nominations are now open. We are accepting nominations through May 31st.**BRANDMEISTER DMR PHASING OUT SOME RADIO IDSPAUL/ANCHOR: Certain Radio IDs that have been in use on the Brandmeister DMR network are going away later this year. Sel Embee KB3TZD explains.SEL: The Brandmeister DMR network has announced that it is phasing out its support of certain Radio IDs that do not comply with the Mobile Country Code, or MCC, numbering system. This means that by June, radio operators with certain DMR IDs will need to request new numbers to be assigned to their radios. The first phase of these changes will begin on the 1st of June, when Brandmeister will stop supporting five-digit CAP+ IDs. Starting on the 1st of January, 2026, radios with seven-digit personal radio IDs that begin with the numeral 1 will also stop working on the network. In making this announcement, Brandmeister assured repeater operators that it will continue indefinite support of repeaters that have six-digit radio IDs.Brandmeister said in its announcement in late February that this an effort to address improperly numbered Radio IDs – something Brandmeister has been trying to contain for seven years. It said on its website: [quote] The Brandmeister DMR platform is a constantly evolving system, requiring regular optimizations and maintenance to ensure its efficiency, reliability, and alignment with global open standards.” [Endquote]New IDs can be obtained through Radio ID (Radio Eye Dee) dot net (Radioid.net).For further instructions visit the Brandmeister link that appears in the text version of this week's newscast at arnewsline.orgThis is Sel Embee KB3TZD.[DO NOT READ: news.brandmeister.network](NEWS.BRANDMEISTER.NETWORK, AMATEUR NEWS DAILY)**3 IRISH "KILMOLIN CLUSTER" BEACONS GO QRT TO RELOCATEPAUL/ANCHOR: A trio of beacons in Ireland have been taken out of service in preparation for being moved, as we hear from Jeremy Boot G4NJH.JEREMY: In Ireland, three beacons that have been operating from a site south of Dublin have gone QRT to allow for their relocation. The EI4RF, EI1KNH and EIØSIX beacons have been part of what is known as the Kilmolin cluster. They had been hosted by Paddy Geoghegan, EI5HS, who became a Silent Key last year.The beacons, which have a new owner, went off the air in mid-February and are expected to slowly come back. According to reports on groups.io and the SWLing Post blog, the EI4RF 4-metre beacon is expected to be the first to return, perhaps by May just as sporadic-E season begins. The EIØSIX beacon is expected to follow sometime afterward on 6-metres. It was unclear how and when service will be restored on the EI1KHN beacon, which operated on 40 and 60 MHz. It is also unclear whether this beacon will need to be assigned a new callsign.This is Jeremy Boot GF4NJH.(EI7GI BLOG, QRZ.COM, SWLING POST)**UNIVERSITY IS W. BENGAL'S 1ST TO HAVE HAM CLUB STATIONPAUL/ANCHOR: Students and faculty in India are celebrating the establishment of the first state-of-the-art shack on a West Bengal state university campus. Graham Kemp VK4BB tells us more.GRAHAM: Aliah University, a state university that created for the education of many of India's minority populations, is about to become the first university in West Bengal with its own state-of-the-art ham radio club station.The announcement was made in late February in connection with a seminar held on the Kolkata campus introducing students and faculty to various aspects of amateur radio. The one-day session, held on the 24th of February, covered emergency communications and radio technology and included hands-on experience for the estimated 250 attendees. It was led by members of the West Bengal Radio Club, the Indian Academy of Communication and Disaster Management and organized by the school's Department of Electronics and Communication Engineering. A number of other schools have hosted similar amateur radio workshops throughout the region, which is a coastal area subject to violent storms and other natural disasters that rely on alternate forms of communication. This is Graham Kemp VK4BB.(MILLENNIUM POST)**BROADCAST TRADE SHOW DROPS RECEPTION FOR HAMSPAUL/ANCHOR: Hams will no doubt be among those visiting the National Association of Broadcasters annual trade show again this year but something will be missing, as we learn from Ralph Squillace KK6ITB.RALPH: The annual trade show of the National Association of Broadcasters is welcoming industry professionals once again this year to Las Vegas in April. One traditional event will be missing from this year's show, however: There will be no separate reception for amateur radio operators.Hams, of course, are still welcome. Indeed, many broadcast professionals - especially those on the engineering side - enjoy an active and robust time on the air on the amateur bands. A posting on the Radio World website said that this year's ham reception was not on the schedule. The reception had been hosted for a long time by Bob Heil K9EID, who became a Silent Key last year.The article said that organizers are hoping to [quote] "reinvent the event for next year by exploring fresh partnerships and innovative ideas." [endquote]In the meantime, licensed hams who work in the industry can still look forward to the usual opportunities for networking and learning about new technology. The NAB Show takes place between April 5th and 9th at the Las Vegas Convention Center.This is Ralph Squillace KK6ITB.(RADIO WORLD)**BREAK HERE: Time for you to identify your station.

We learn more from Jason Daniels VK2LAW.JASON: It's still early in the game for the newly organized not-for-profit DX India Foundation but the team has already announced ambitious plans to increase India's presence on the DX map. As part of its mission to activate rare IOTA islands, conduct DXpeditions and provide DX and POTA chasers with a chance to work different entities in India, the team has its sights set on Arnala Island, IOTA number AS-169, which is near Mumbai. According to an announcement from the team, the island has had no amateur radio activity since 2006. Hams from the DX India Foundation have applied to use the callsign AU2M and hope to be on the air from the 29th of May through to the 1st of June. Later plans include a 10-day adventure to the Lakshadweep archipelago off the coast of Kerala [CARE-ruh-luh] in southern India.The DX India Foundation has also established an online forum in groups.io to encourage a sense of international community for chasers and activators. In between trips, the foundation's activity will be focused on training and mentoring other radio operators.This is Jason Daniels VK2LAW.(DX INDIA FOUNDATION)**HUNTSVILLE'S ‘SIGNALS' MUSEUM OPENS IN ALABAMAPAUL/ANCHOR: Huntsville, Alabama, home of the Huntsville Hamfest, has a new way to celebrate technology and, of course, amateur radio. To welcome the museum and honor the spirit and advancements made in technology, Newsline is departing from the norm this week. This report is being read via artificial intelligence and a correspondent known as AI-Drew.AI-DREW: On March 1st, the SIGNALS Museum of Information Explosion opened its doors to what founders hope will be an immersive and hands-on environment for visitors. The museum, housed a short drive from where the Huntsville Hamfest is held each year, has an array of exhibits devoted to communications technology in all its forms throughout history. Amateur radio operators who are visiting will be particularly interested in the ham shack, a welcoming space for regional radio clubs and other radio operators to meet or work on building equipment. The museum also has an on-site radio tower.Whether you live in the area or plan to visit Huntsville this year, the museum will welcome you. Visit their website at signals hyphen museum dot org.

He has become a Silent Key, as we hear from Randy Sly W4XJ.RANDY: It can be said that the seeds of the Hurricane Watch Net were planted in 1965 as Hurricane Betsy raged its way through the Bahamas, making landfall in the US that September. Gerald Murphy, K8YUW, who was stationed by the US Navy in Rhode Island at the time, was also handling messages and phone patches for the Intercontinental Amateur Radio Net. When hurricane-specific traffic started to overwhelm the regular net's messages on their 20m frequency, Gerry suggested that those messages be handled 5 kHz higher. Marcy Rice, KZ5MM, who was in the Panama Canal Zone QSY'd with him up to 14.325 MHz and that was the genesis of the Hurricane Watch Net.The net has become the backbone of a robust communications system during storm season. Trained hams share advisories, data and post-storm damage information in affected areas with national hurricane centers in the US and, when needed, Canada.Gerry, who became a Silent Key on the 25th of February at the Ohio Veterans Home in Sandusky, leaves behind this vibrant legacy. He served as net manager from September of 1965 until February of 1988, staying on afterward as assistant net manager. Health issues compelled him to retire from the net in March 1991.The Hurricane Watch Net has been planning an on-air special event in September to mark its 60th anniversary. Net manager Bobby Graves,KB5HAV, told Newsline [quote] "I was hoping and praying Jerry would make it to see his creation's 60th Anniversary this coming Labor Day....We will endeavor to make it even more special." [endquote]Gerry was 88.This is Randy Sly W4XJ.(BOBBY GRAVES, KB5HAV; EDDIE MISIEWICZ, KB3YRU)**WORLD OF DXIn the World of DX, Chris, WA7RAR, is on the air until the 16th of March from Barbados, IOTA Number NA-ØØ21. He is using the callsign 8P9CB, operating SSB and CW on 20-10 metres. Some of his locations are POTA sites. See QRZ.com for QSL details.Rockwell, WW1X, is using the callsign VP5/WW1X from Providenciales, IOTA Number NA-ØØ2 in the Turks and Caicos Islands from the 8th through to the 15th of March. This is a QRP operation using only SSB, although Rockwell has not ruled out occasional use of FT8. QSL via LoTW.Listen for Aldir, PY1SAD, who is using the callsign 8R1TM from Georgetown, Guyana, between the 11th of March and the 26th of April. Aldir is using CW, SSB and the digital modes on the HF bands. He is also operating via satellite.

They are using the callsign HL1ØØIARU. See QRZ.com for QSL details.(425 DX BULLETIN)**KICKER: ECHOES OF A DIFFERENT WAY TO LEARN CWPAUL/ANCHOR: We end this week's report with an alternate way in which some hams in New Zealand got to learn and practice CW while having real QSOs. We'll let Jim Meachen ZL2BHF explain how it happened.JIM: If you've ever wondered whether Echolink is a viable mode for teaching or learning CW, just ask Ted ZL1BQA, who is proud to have logged a respectable number of CW contacts during the recent Jock White Memorial Field Day in New Zealand. Studying CW for almost a year with the Franklin Amateur Radio Club, Ted was able to restart his long-ago code skills in sessions led by the club president Peter Henderson ZL1PX. It was done over Echolink.Ted had enrolled last May along with three younger members who were first-time learners - Francois, ZL4FJ, Steve, ZL1TZP and Steve ZL1SPR. With only Ted able to copy Peter's signal over HF, the club followed a suggestion made by Gary ZL1GAC: try Echolink, a computer-based ham radio mode that incorporates VoIP technology. Loading CW software onto his computer, Peter was able to send the code intended for each session, confident that everyone had an equal chance of copying clearly.Weekly sessions soon expanded to twice a week as the students concentrated on letters, then numbers - and eventually basic punctuation.After a break in the action, the club is back on Echolink with CW sessions three nights a week. As for Ted, he's on a roll. Peter told Newsline in an email that he has resumed making CW contacts on a daily basis on HF using the Vibroplex that once collected dust instead of QSOs.This is Jim Meachen ZL2BHF.(QUA, Peter Henderson, ZL1PX)**Have you sent in your amateur radio haiku to Newsline's haiku challenge yet?

In this episode, Matt and Chris take a look at a recent developmental psychology paper on the social evaluation of young babies. Do they display a preference for agents who are nice to others or could they care less at the babbling age? This is a large-scale, multi-lab, preregistered replication effort of a rather influential paper so it ticks all of Chris' Open Science boxes, but how does Matt react? Is he stuck in his pre-replication crisis paradigms? Join us to find out and along the way find out about baby Matt's psychotic tendencies, how cats feel about cucumbers, and how Matt narrowly escaped being eaten by a big ol' crocodile.Paper Reference: Lucca, K., Yuen, F., Wang, Y., Alessandroni, N., Allison, O., Alvarez, M., ... & Hamlin, J.

Walt Hudson, K4OGO, has always lived by and had a love of the sea, pursuing a career in ship building, beginning in Port Smith, Virginia.  While he always had an interest in radio, including Citizens band radio, it wasn't until just a few years ago that Walt became a ham radio operator. Since he is always near the shore, operating portable QRP SSB from the water's edge and making DX contacts is what excites him.  K4OGO loves to experiment with vertical antennas on the beach to fine tune his technical and operating skills.  K4OGO is my QSO Today.

Adam Kimmerly, K6ARK, discovered amateur radio almost by accident through his participation in the San Diego Mountain Rescue organization.  Adam's ham radio interests evolved from VHF to HF SOTA, or Summits on the Air, learning CW, and reaching SOTA Mountain Goat status.  The need for light weight kits to carry to the most difficult to reach summits demanded new expertise in antenna design and construction with 3D printing.  K6ARK tells his ham radio story in this QSO Today.

My guest this week is Willi Kraml, OE1WKL, creator of the Morserino CW code practice machine .  Willie  discovered amateur radio as a boy in Lindz, Austria, but had to wait until the legal age of 16 to get his license.  With his doctorate in linguistics, Willi pursued a career in IT security with KPMG.  When his local makerspace needed an Arduino project around amateur radio, the Morserino code practice system was born.  OE1WKL discusses the delivery of over 10,000 Morserinos, his projects, and his contributions to amateur radio in this QSO Today.
