Foundations of Amateur Radio

Starting in the wonderful hobby of Amateur or HAM Radio can be daunting and challenging but can be very rewarding. Every week I look at a different aspect of the hobby, how you might fit in and get the very best from the 1000 hobbies that Amateur Radio represents. Note that this podcast started in 2011 as "What use is an F-call?".

Finding your path in this hobby

Foundations of Amateur RadioAs you might recall, recently I stumbled on an excellent list of 52 weekly challenges put together by Fabian, DJ5CW and friends. You can find it at hamchallenge.org. As I've previously mentioned, it contains activities right across the amateur spectrum, from designing a QSL card to making a contact on 80m or 160m, with everything in between. It's an excellent tool to set a weekly goal to achieve and I recommend that you have a go. It's not the only interesting tool

Foundations of Amateur RadioThe other day I was sitting on the couch lounging about when I came up with an idea and there and then I picked up a circuit board, soldered down a hundred or so components and built a noise cancelling gadget, all within about an hour .. right there, on my couch. Yeah, that didn't happen, least of all, my soldering skills are not up to scratch, never mind the couch. I did however build a noise cancelling circuit, on my couch, in about an hour, but no soldering iron

WSPR beacon QSY to 15m

2025/01/18

Foundations of Amateur RadioFor quite some time I have operated a WSPR or Weak Signal Propagation Reporter beacon on the 10m band. If you're not familiar with it, I've dialled the power right down to 10 dBm, or 10 milliwatts. You'd think that this would be a fool's errand, but it was heard 13,945 kilometres away. Of late the reports have been far and few between, despite the 10m band being quite active. Encouraged by a friend playing on 15m, I made the decision to change bands. At the moment this

Foundations of Amateur RadioThe other day I noticed a flurry of QSL card designs come across my screen and it sparked me into action on actually creating such a card for myself. I've previously talked about what I think of the current offerings in terms of validating contacts, but having a QSL card design is step one of confirming a contact, well, technically step two, since you have to make the contact first. I'm intending to use SVG as the design platform, since it's a text file that describes

2025/01/04

Foundations of Amateur Radio Life is messy. This is not a revelation. We attempt to organise this chaos by using all kinds of magic incantations, to-do lists, new year resolutions, plans, projects and anything else you might have in your arsenal. The same chaos reigns, in how we make progress. Some days are harder than others. I'm mentioning this because I've seen a couple of amateurs share all the things they didn't achieve last year. If we used that metric, I could point out that I didn't win the

Foundations of Amateur Radio As you might know, a little while ago I started a new project. "The Bald Yak project aims to create a modular, bidirectional and distributed signal processing and control system that leverages GNU Radio." In embarking on this adventure I've been absorbing information as I go whilst explaining what I've learnt to anyone who will sit still long enough. Credit to Glynn VK6PAW and Charles NK8O for their patience. For most people, me included, the introduction to GNU

Foundations of Amateur Radio In the analogue world you throw up an antenna, turn on your radio, tune to a station and sound comes out. Aside from propagation restrictions, you don't particularly care when you do this. In contrast, if you fire up a WSPR or Weak Signal Propagation Reporter, each transmission lasts 110.6 seconds, every 120 seconds, starting on the even minute. An FT8 signal takes 12.6 seconds within a 15 second window. In other words, to use WSPR or FT8 you need to both transmit and

Bald Yak - week 3 - Push To Talk

Foundations of Amateur Radio ·

2024/12/14

Foundations of Amateur RadioWhen you key your transceiver, as-in, you trigger the Push To Talk or PTT button, you close a switch that activates the transmitter and in turn allows your voice to make it through the microphone and radio, via the coax out to the antenna and the world. When you release the button, the transmission stops. This is pretty much how we're taught that a radio transceiver works, essentially switching between transmit and receive, depending on the state of that magic

Foundations of Amateur RadioBald Yak, week 2 During the week an interesting question was put to me. Am I going to make this into a GNU Radio tutorial? In short, no and yes. At this point I know enough about what I'm attempting, to recognise that I'll be deep diving into the bowels of GNU Radio and the inevitable idiosyncrasies that a large project like that has and as a result I'll likely have to explain the context in which something broke, which will no doubt result in me having to walk you

Foundations of Amateur RadioIn the process of developing something from scratch there are a great number of things that need doing. When you start it's unclear what's the most important thing, but experience has told me that starting, anywhere, is the best way to get runs on the board. Here's a smattering of what I'm talking about. What do we call this thing? How will we license it? What does it do? How will we determine what is required and what is nice to have? How will we avoid reinventing the

Foundations of Amateur Radio Thirteen years ago I opened my mouth to express my thoughts on what to do with an amateur license after hearing an operator complain they needed more power to talk to a station across 600 kilometres, whilst I used the same 10 Watts to communicate with a station nearly 15,000 kilometres away. In all, I've shared my thoughts some 700 times, documenting my journey though this majestic hobby, describing what I've been up to, reporting my successes and failures, sharing my

Foundations of Amateur Radio The hobby of amateur radio is one of experimentation and change. For decades this came in the form of circuit diagrams, components and scrounged hardware from anything that wasn't bolted down. New functionality came with the aid of a soldering iron. More recently, functionality comes from participation in the global electronics market where you can buy any radio you like and have it shipped to your door within hours at an unbeatable price. Mind you, buying all those

Foundations of Amateur RadioOver the past weeks, actually, probably more accurately years, I've been carrying around an idea. It's been bubbling away and I've been trying very hard to make it solidify into something that I could explain and then hopefully attack. Today I woke up with a hunger to do some radio and ultimately tell you about it. To get to a point where my Aha! moment emerged, I need to provide some history. Traditional radio activities involve variations on a radio plugged into an

The venerable QSL bureau

2024/10/26

Foundations of Amateur Radio One of the oldest global aspects of our hobby, other than actually using the radio, is the QSL bureau. It uses a postcard-like system to confirm that two stations made contact, sent via the postal service as a so-called QSL card. Of course, that only works if you have each other's address which after World War II was somewhat difficult. As a result the QSL bureau was born. Intended as a single point of contact for a country, a local QSL bureau consists of one or more

Amateur Radio connects you in unexpected ways

Foundations of Amateur Radio One of the unexpected benefits of this hobby is how it provides you with the ability to connect to others in ways that are not directly related to radio. Take for example Steve. Steve appears at unpredictable times and locations, been hunted by citizens and scientists and unlike Steve's potential invisible cousin, the proton arc, has been photographed by aurora hunters many times. It looks like observations go back as far as 1705. In 2017, physics professor Eric

Foundations of Amateur RadioEvery now and then you come across an idea that throws you for a loop. It comes seemingly out of nowhere and once you've seen it, you cannot unsee it. It's a lot like a 1929 painting I like called "The Treachery of Images", also known as "Ceci n'est pas une pipe", or in English, "This is Not a Pipe" by Belgian surrealist painter René Magritte. If you're not familiar with it, it's a painting of a pipe, and by being a painting, it's not a pipe. Obviously. Before I go

Foundations of Amateur RadioThe other day I was packing the car to go on a little trip an hour out of the city to see the Milky Way. I briefly entertained the idea of bringing my radio gear with me to get on air to make some noise. I resisted the urge, mainly because thinking about this didn't fill me with joy, rather it made me groan. Now to be absolutely clear, I adore going out into the scrub with my radio gear. I love getting on air and making noise. I like doing this with friends. If the

Foundations of Amateur Radio Over the past few months I've been investigating the history of the IARU, the International Amateur Radio Union, to help it celebrate a century of amateur radio achievements. If you're a radio amateur and you pay anyone a membership fee, I have questions for you.

Foundations of Amateur Radio As I sit here, away from my shack, I'm overlooking a picturesque valley that I'm visiting for a couple of days to see the stars. I learnt recently that my SO, Significant Other, had never seen the Milky Way with their Mark One Eyeball and we thought that it would be fun to remedy that. One of the challenges in accomplishing this is that we're surrounded by light almost everywhere we go. Street lights, porch lights, car lights, stadium and building lights, traffic
