Este episodio 163 de CQ en Frecuencia ha dado un giro inesperado durante su preparación. Mi intención inicial era dedicar una nueva entrega de nuestro "Álbum Sonoro de las Entidades DXCC" a Monte Athos, la singular entidad SV/A. Sin embargo, al comenzar la documentación descubrí algo sorprendente: existe muy poca información disponible en castellano sobre este fascinante enclave y sobre las personas que han mantenido viva su presencia en las bandas de radioafición durante décadas. Por eso, este episodio se transforma en un auténtico monográfico dedicado a una de las entidades más peculiares, misteriosas y especiales de todo el programa DXCC. Así que esta semana, en lugar de coger el pasaporte, vamos a solicitar el Diamonitirion, el permiso especial necesario para acceder al Estado Monástico Autónomo de Monte Athos, un territorio único donde la historia, la espiritualidad y la radioafición se encuentran de una forma difícil de encontrar en cualquier otro lugar del planeta. Comenzaremos descubriendo qué es realmente Monte Athos, por qué constituye una entidad DXCC independiente, cómo nació la actividad radioaficionada en este enclave y quiénes han sido las figuras que marcaron su historia, desde el legendario monje Apollo, SV2ASP/A, hasta las activaciones más recientes que han vuelto a situar a Athos en el centro de atención del mundo DX. Pero este episodio incluye además un documento muy especial. Tras mucho investigar, apenas encontré entrevistas al monje Apollo. Las pocas existentes se encuentran en griego y, en la mayoría de los casos, sin traducción ni subtítulos. Así que decidí hacer algo que, sinceramente, creo que merecía existir. He transcrito, traducido y adaptado una de esas entrevistas para que cualquier radioaficionado de habla hispana pueda descubrir la historia, las reflexiones y la personalidad de quien fue durante décadas la voz de Monte Athos en las bandas. Un trabajo realizado a partir del material original compartido por Polykarpos Papadopoulos, a quien agradezco haber preservado este valioso documento histórico, y cuyo enlace encontraréis en las notas del episodio. Y para cerrar el programa, estrenamos una nueva sección que nos acompañará en algunos episodios a partir de ahora. Nuestro joven compañero Nicolás, EA4BTQ, recientemente seleccionado para participar en el campamento YOTA 2026 en Austria, sale al encuentro de otros radioaficionados con preguntas rápidas, directas y espontáneas para descubrir quiénes son las personas que hay detrás de los indicativos. Todo ello en un episodio dedicado a una entidad DXCC que no se parece a ninguna otra. Porque Monte Athos no es solo una referencia en el log. Es historia viva. Es tradición. Es radioafición. ¡Páme! ¿Nos apoyas para que podamos seguir haciendo este podcast?

Stuart M0SGV started soldering at age 8 in the 1950s, building crystal sets with a copper tip heated over a gas cooker. Nearly 70 years later he is still at the bench, building tube transmitters from 1949 magazine circuits, Hans Summers QMX and QDX rigs, a Michigan Mighty Mite, and a high voltage power supply built from scratch to power all of it.In this episode Stuart walks us through a dozen homebrew projects, shares his philosophy on project selection, and offers hard won advice on soldering and why leaded solder is non-negotiable. We also talk about his connections to the Michigan QRP Club and G QRP Club, and his next big project: a QO-100 geostationary satellite transceiver.Join us as we explore how you can get involved in portable radio, QRP, and more in this episode of the All Portable Discussion Zone (AP/DZ).

Foundations of Amateur Radio The other day I witnessed a fellow amateur attempting to guilt another into using LoTW with comments about how their QSO partner would appreciate confirmation via the service, even if they didn't care for it. Before I continue, if you're unfamiliar, when two amateurs make a contact, or a QSO, with each other, then there's generally a log entry at both ends to record the event. Some amateurs, myself included, save up these contacts and count how many continents, countries, states and other entities are recorded in the log. Several amateur radio organisations allow you to claim an award for such a record. However, before they accept your word for it, they require confirmation of the contact, something that the amateur community refers to as a QSL. To recap, a QSO is the contact, a QSL is the confirmation of that contact. Traditionally this was achieved with postcards, known as QSL cards, transported across the globe through various postal services, and coordinated by so-called QSL bureaus, often run by the amateur radio peak body in each country. With the advent of the Internet, much of this process has turned electronic. LoTW is an example of an electronic QSL service, run by the ARRL, the American Radio Relay League. It's not the only such service, but today I'm looking specifically at the Logbook of The World, or LoTW. As I said, LoTW is not the only service and anyone telling you that you must use it is selling you something. Now, that's not why I don't use it, and again, you're free to, but you're not required to. For me there are several issues with LoTW. Having used it for a period, I feel comfortable in expressing some of its shortcomings, but I note that the last time I used it was almost a decade ago. I'll acknowledge that things might have improved or changed, but I have no evidence to suggest that it did. Let's start with how it works. You create a log in a specified format, using an application called TQSL you sign that log, ostensibly linking your identity to that log, then you upload that signed log to LoTW and wait for confirmations of contacts with other LoTW users. Signing is a process where you add information to a file that proves to the recipient that the log was created by you and wasn't modified in transit, which requires that you have a file called a certificate, which is created and sent to you via email by the ARRL, after they've authenticated you. So, first of all, in my opinion, the level of security is absurd and exceeds that of my bank, or my tax department. In addition, proving your identity comes with hurdles if you're not in America where an amateur who registers receives a postcard with an authentication code, made possible by the central database held by the FCC. For everyone else, the ARRL requires that you: "must send a copy of his/her Amateur Radio operating authorization in addition to a copy of one other government-issued document indicating his/her identity", via the post, snail mail, stamp, envelope, the whole thing. I'd also like to observe that at no time has the ARRL linked your identity to your email address, since they haven't asked for it at any point in the verification process. If that's not enough of a security nightmare, in Australia and other parts of the world, amateurs no longer hold a personal license, instead they are members of a so-called class license. There's no public record stating my ownership of my callsign, just that it's allocated. With increased privacy concerns, this is happening elsewhere too. In other words, proving that you are who you say you are is getting increasingly difficult and even if you did, you're sending that information to the ARRL, who you might recall paid a ransom to hackers who infiltrated their network. I've asked and never received a response about what actually happened to the information they continue to hold in relation to me, well that and an email from 2013 which states that "Data is never removed from LoTW." Even so, let's say that you are comfortable sending your information to the ARRL, the process of signing a certificate requires renewal on a regular basis and if you manage to forget, you have the privilege of starting all over again. Let's move on. It's important to remember that this process is to confirm a radio contact between two radio amateurs in order to get a piece of paper to hang on your wall saying that you did so. How do you know that the person you made contact with on-air is the same person who confirmed your contact? Radio isn't authenticated in any way, why should the confirmation be? Remember, before the Internet, this was done with postcards. Security and authentication aside, there's plenty more issues. I hold the callsign VK6FLAB. Several times a year, that callsign is permitted to be AX6FLAB. I like to operate portable in many different locations. Sometimes I sign "/QRP" for low power, generally if the other station is very high power and they're struggling, adding QRP can sometimes act as an incentive to complete the contact. Sometimes I sign Portable, or Mobile, depending on the situation and when I'm moving, I'm not in a specific location. Why am I raising this you ask? Well, turns out that you need to make a new location for every single one you're operating from. You also need to register each callsign and each variation, since apparently VK6FLAB and VK6FLAB/QRP are two different stations and if I sign with AX6FLAB, I need to request another certificate. So, this is increased convenience .. apparently. Then there's the argument that you're missing out. Let's get this straight. As far as I can tell, the bulk of LoTW users are American. For me, a contact with America is a single log entry to add to my continent and country list. Tell me again why I should care about this when I'm not in America? There's a list of 340 DXCC entities, which you can buy from the ARRL for $5.95 plus shipping, because of course in this digital age there's a shipping charge. In other words, this is the ARRL attempting to own the notion of confirming contacts between radio amateurs and in my opinion, being obnoxious about it. Here's another issue. If this was really so marvellous, why hasn't any other peak body adopted the Logbook of The World for their system? Why is there not a WIA version, an RSGB one and for each of the various countries who have closed their local QSL bureau due to lack of funding, since the postal burden on them has exploded to become nonviable? I think that LoTW is a solution looking for a problem, peddled by people who have something to sell and while there was a time that it might have been bleeding edge, that ship has sailed. You're free to use it, but I wouldn't recommend it. If you have never stepped into this, alternatives to explore include ClubLog, eQSL, QRZ, OQRS and plenty of print on demand QSL card services. And if you're searching, apparently QSL is also Queensland Sugar Limited, so pay attention. I should also mention that there's SOTA, Summits, POTA, Parks and other On The Air services that will happily take your log and confirm contacts. Here's a thought, how about we use the fediverse to federate and decentralise the process, or perhaps we might use something as mundane as email. If you want to use LoTW, by all means, go right ahead, but I won't and if I knew how, I'd get the ARRL to remove all my records from it, mind you, I'd have to trust them at their word, because I can't log in to check. I'm Onno VK6FLAB

En el episodio 160 de CQ en Frecuencia hablamos de uno de los aspectos más importantes —y muchas veces más olvidados— de nuestra estación de radio: la alimentación eléctrica. Comentamos por qué nuestros equipos trabajan a 13,8 voltios en corriente continua, la importancia real del amperaje, cómo influye la sección del cable en el rendimiento del equipo y qué problemas pueden provocar unas malas conexiones o una instalación deficiente. También hablamos de fuentes lineales y conmutadas, distribución DC, ferritas, masas, conectores Anderson Powerpole y el papel fundamental de los fusibles en cualquier estación de radioaficionado. Además, repasamos la celebración del XX Mercarradio de Torrent, en Valencia, viajamos hasta la remota entidad DXCC Bouvet, 3Y, y terminamos recordando el próximo encuentro QRP organizado por el grupo Conecta Radio Canarias este miércoles. ¿Nos apoyas para que podamos seguir haciendo este podcast?

En el episodio de esta semana de CQ en Frecuencia nos vamos a tres frentes muy distintos… pero igual de interesantes para cualquier amante de la radio. Por un lado, seguimos con la parte más didáctica y hablamos del ancho de banda, un concepto clave que muchas veces tocamos en nuestros equipos sin tener del todo claro qué hace realmente. Veremos cómo influye en la recepción, cómo ajustarlo correctamente y por qué puede marcar la diferencia entre escuchar limpio… o lleno de interferencias. En el apartado de DX, ponemos el foco en una entidad poco habitual y muy buscada: San Félix Island, una referencia que despierta el interés de muchos cazadores de entidades por su rareza y localización remota en el Pacífico. Y además, nos acercamos a la actividad en portable con el meeting SOTA de primavera en Bronchales, un evento que combina radio, montaña y buen ambiente entre colegas de afición, en plena naturaleza. Un episodio variado, con técnica, DX y actividad en campo… como nos gusta en CQ en Frecuencia. ¿Nos apoyas para que podamos seguir haciendo este podcast?

En este episodio arrancamos mirando al aire con una de esas historias que nos recuerdan por qué la radio sigue teniendo magia. Hablamos de la última activación del grupo Conecta Radio de Canarias, una cita ya habitual en QRP en HF… La conexión Canarias - Península, en esta ocasión, aunque ya desde QTH, nos dejó un contacto muy especial en VHF: más de 1.500 km entre Galicia y Canarias gracias a un canal de propagación troposférica típico de estas fechas. Escucharemos el QSO entre EA1FTW, en un SOTA desde Ourense, y EA8CAZ desde Tenerife, en una de esas aperturas que hay que aprovechar cuando el Atlántico decide “abrirse”. Después nos vamos hasta Oviedo para charlar con Kike, EB1RD, del Radio Club Vetusta, sobre la próxima edición del Mercau Astur Radio, que se celebrará el 16 de mayo de 2026. Y cerramos estrenando nueva sección: un recorrido por las entidades DXCC. Empezamos fuerte con una de las más raras y deseadas… P5, Corea del Norte. Radio, experiencias, eventos y DX… todo en un mismo episodio. ¿Nos apoyas para que podamos seguir haciendo este podcast?

Brad Donald Johnson of MacGregor, VK4BRA whose old call was VK4AIR passed away on 25 March 2026. Brad VK4BRA had been in radio from 1976 as many of us were , as a CBer. Brad passed with a full licence in Amateur Radio in 1979 and worked as a light and sound engineer in his own business. He is survived by 2 sons. The next Ipswich WICEN-supported event is the Brisbane Trail Marathon on April 26 held in the South D'Aguilar National Park. It features the ultimate trail running challenge. Start and finish is at Enoggera Reservoir, The Gap. This is a big event so I'm sure the club's WICEN coordinator will not turn away any additional volunteer radio operators and supporters to work the various safety check points along the trail. If you have never participated before, you will be paired with an experienced operator. To volunteer please contact Paul at VK4PMCPaul@outlook.com I'm John VK4JPM, Secretary of the Darling Downs Radio Club. By the time you hear this, RedFest will be over, and I know there will be people we met who have forgotten our email address already, so here it is: secretary@ddrci.org.au and the home page is at ddrci.org.au, which is where you'll find all the details on what follows. This week reminders that our next club tech and chat meeting will be streamed and in person, and for this month is a week later on Monday 20th of April. No doubt those who return from RedFest will have a bit of show and tell - so bring stuff along - and we have some tech discussions following our outing at John Moyle. And watch this space: there could be a surprise guest. the next bimonthly club lunch is due and that's going to be on 26 April at the Southern Hotel in Toowoomba... south, down Ruthven Street. We've booked the table, and festivities start from 1200. By the way, the hotel has erected a massive solar array which doubles as over-cover for car parking. Quite clever. * last week I mentioned that we're doing another run of licence assessments, and you don't have to be in Toowoomba to work with us. We have four ACMA-accredited advanced assessors, which means we're qualified to take all kinds of special conditions into account, including remote delivery. If you are thinking of getting or upgrading a licence, please talk to us, and start by sending an email to education@ddrci.org.au. * Personal admission: life has been hectic and I didn't get to this week's QRP transmitter project even though I have a cupboard full of Raspberry Pi boards. And I'm still trying to get to Großreinemachen which is the big magic cleanup. But... while you're waiting for me to claim success, why not try this week's challenge which is "operate in an uncommon digital mode". There's a hint on the website at hamchallenge.org, and scroll down to week 16. We love hearing from members and anyone interested in amateur radio. To do that, and to be added or removed from our mailing list, drop a line to secretary@ddrci.org.au. Everything we do is on the website at ddrci.org.au, and you can trust that to be correct. So the reminder: why not come and say hi to us at the club meeting or club lunch in a week. BIG hint: that's a way of achieving the challenge from week 17. Simples! And the club net follows the Sunday morning edition of QNEWS on VK4RDD at 1000 actual time. Until next week, I'm John VK4JPM. 73 from Darling Downs Radio Club.

FE DE ERRATAS: No es la primera vez que el ojo humano ve la cara oculta de la luna, como comento en el episodio...Misiones Apolo anteriores ya tuvieron esa suerte en su órbita lunar. Errare humanum est y rectificar también es humanum. Mientras grabamos este episodio, una nave tripulada del programa Artemis program viaja hacia la Luna. Pero más allá del cohete, la cápsula o la propia misión… hay algo mucho más silencioso y absolutamente crítico: el enlace de comunicaciones. ¿Cómo se mantiene una conversación a casi 400.000 kilómetros de distancia? ¿Qué hace posible que una señal llegue, se reciba y se entienda en condiciones extremas? En este episodio exploramos las bases reales de las comunicaciones espaciales: las bandas de trabajo (S, X y Ka), la infraestructura que lo sostiene todo en Tierra y los límites físicos a los que se enfrenta cualquier enlace de radio en espacio profundo. Y lo hacemos desde un punto de vista muy cercano: el paralelismo con el rebote lunar (EME). Porque lo que ocurre en Artemis no es magia… es la misma radio que usamos nosotros, llevada al límite. Además, analizamos el papel de nuevas tecnologías como el sistema O2O, basado en comunicaciones láser, que promete multiplicar la cantidad de datos transmitidos desde el entorno lunar sin sustituir —al menos de momento— a la radio tradicional. Un episodio sobre señales débiles, precisión extrema y una idea fundamental: que desde una estación de radioaficionado… hasta una misión tripulada alrededor de la Luna, todo consiste en lo mismo. Que una señal llegue. ¿Nos apoyas para que podamos seguir haciendo este podcast?

En este episodio respondemos a una consulta muy habitual entre quienes están empezando (o retomando) la radioafición: el miedo a hacer contactos en inglés. Y ya te adelanto algo… no necesitas saber inglés para hacer radio en inglés. Hablamos de operativa básica, de cómo lanzarse sin miedo y de por qué, al final, todo se reduce a unas pocas estructuras que se repiten constantemente en los QSOs. Además, incluimos un ejemplo práctico de contacto completo para que veas que es mucho más sencillo de lo que parece. También comentamos la DXpedition XX9W en Macao, una entidad DXCC interesante, con historia propia y no siempre fácil de trabajar desde EA. Una buena oportunidad para meterla en el log o trabajarla en nuevas bandas y modos. Y, como no podía ser de otra forma, ponemos el foco en el CQ WPX Contest, que se celebra este próximo fin de semana (28 y 29 de marzo). Un concurso dinámico, ideal tanto para principiantes como para operadores más experimentados, perfecto para poner a prueba la estación… o simplemente disfrutar de la radio. Y para cerrar, nos metemos en un tema más técnico pero muy útil: ¿Qué es una dummy load y para qué sirve realmente? Una explicación clara y práctica sobre este elemento imprescindible para hacer pruebas sin salir al aire y cuidar nuestra estación.

Welcome to Episode #71, and today we're talking about one of the great elements of the hobby — QRP. That's right, making contacts across states, across continents, even across oceans… all with less power than it takes to light up a nightstand lamp. In this episode, we'll explore what QRP really means, the history and philosophy behind running low power, the gear and antennas that make it possible, and the community of hams who thrive on doing more with less. Along the way, I'll share stories, tips, and even a challenge for you to try the next time you're on the air.

En este episodio del podcast hablamos de radioafición, onda corta y estaciones misteriosas. Escuchamos un fragmento real de una estación de números en farsi conocida como V32, detectada a finales de febrero de 2026. Esta transmisión, probablemente dirigida hacia Irán, emite grupos de números cifrados y ha sido objeto de interferencias (jamming) por parte de transmisores iraníes. Analizamos sus frecuencias, horarios y posible origen en Europa, y qué podría significar dentro del contexto geopolítico actual. También escuchamos una grabación reciente de Voice of the Islamic Republic of Iran (IRIB) captada en 15.135 kHz en la banda de 19 metros, una de las pocas emisiones que todavía mantiene Irán en onda corta, después de que muchas de sus transmisiones internacionales se hayan trasladado a onda media, satélite e internet. Además, charlamos con EA1FTW, que acaba de alcanzar los 1000 puntos como activador en SOTA (Summits on the Air), lo que le convierte oficialmente en “Mountain Goat” o cabra montesa, uno de los hitos más conocidos dentro del programa SOTA. Y obviamente, cuento mis primeras experiencias con una antena end-fed instalada en la fachada, con la que ya han salido contactos interesantes: Bouvet en FT8 Anguilla en fonía Todo esto demuestra que, incluso con una simple antena de hilo, la radioafición y la onda corta siguen conectando el mundo. ________________________________________ Temas del episodio • Estación de números V32 en farsi • Espionaje y mensajes cifrados en onda corta • Voice of the Islamic Republic of Iran (IRIB) en 15.135 kHz • Propagación en la banda de 19 metros • SOTA – Summits on the Air y el logro Mountain Goat • Antenas end-fed y DX desde casa • Contactos de radioafición en FT8 y fonía ________________________________________ ¿Nos apoyas para que podamos seguir haciendo este podcast?

En este episodio nos vamos de madrugada hasta la sede del Radio Club Fene, EA1RKF para vivir desde dentro su participación en el CQ World Wide 160-Meter Contest. Escuchamos el ambiente real del shack durante la noche del concurso: ruido de banda, contactos y conversaciones entre operadores mientras intentan sacar señales débiles en la exigente banda de 160 metros. La estación trabajó con unos 800 vatios sobre una delta loop monobanda elevada con una grúa de 40 metros, logrando finalmente 152 contactos y una puntuación reclamada de 23.991 puntos, con estaciones principalmente europeas y un DX destacado con Israel. Además, repasamos el Diploma Día de Andalucía, que este año celebra su quinta edición, y terminamos el episodio con algunas primeras impresiones y “batallitas” probando una nueva antena End-Fed en configuración sloper. ¿Nos apoyas para que podamos seguir haciendo este podcast?

In this video, Rex Harper (W1REX) shares the remarkable history of the Tuna Tin II, one of the most beloved homebrew QRP radios in amateur radio.Originally designed by Doug DeMaw (W1CER), the Tuna Tin II began as a simple, clever transceiver built into a literal tuna can. Over the years, the design was adopted by multiple ham radio clubs, evolving into a variety of kits as different organizations took on production and sales.Rextells how the design changed hands, how the kits evolved, and how the Tuna Tin II ultimately ended up under his stewardship. He also tells the story of taking the original Tuna Tin II on the road—touring ham radio events and sharing its history with fellow operators.Rex's QRPme website: https://www.qrpme.com/Join us as we explore how you can get involved in portable radio, QRP, and more in this episode of the All Portable Discussion Zone (AP/DZ).

Join me for my first Parks on the Air (POTA) activation using the brand-new ICOM IC-7300MK2 HF transceiver!

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
