  • The history of our hobby

    Foundations of Amateur Radio

    The other day I was handed a sheaf of paper. The person handing it to me, an amateur, was insistent that I take custody of this little collection. I asked what it was that they intended for me to do with it and the response was that because I did things with history, I should do this too.

    Aside from taking on a new project, trying to juggle life and income, their observation was pretty spot on, even though I had never quite seen it in that way. Over the years I've often explained things in the context of the era in which it came into being, the first transatlantic telegraph cable in 1858, the first 20m contact between the UK and Australia, back in 1925, the founding of the IARU, also in 1925.

    For some years I've been playing with the idea of documenting the journey from Spark Gap to SDR. I started writing down milestones, collecting information about the various protagonists along the way, attempting to capture their life milestones and their radio related accomplishments. One friend went so far as to take photos of the replica spark gap transmitter in Hobart, Tasmania as used by Douglas Mawson between 1911 and 1914 during their Antarctic expedition.

    Between being entrusted with the written history of 28 Chapter of the Ten-Ten International Net and today I've started a spreadsheet. If you know me at all, you know that I love a good spreadsheet. This one is pretty simple, date, event, event type, protagonist, note and source. So far I've got about 85 rows. I'm using it to capture milestones directly related to our hobby, when the first EchoLink node went live, when RTTY came to be used on-air, the invention of FM, when we got access to the 2m band, when 160m was taken away during World War II, ultimately, all of it.

    There is already a website that documents some of this but it's USA centric, even though our community is global, and it does not include any sources, so there's no way to verify any of the events, which I think is essential if you're going to capture this in any meaningful way.

    I want this list I'm creating to include all manner of amateur related things, the first time F-troop went on-air, the first CQWW, perhaps even every CQWW. I have also set-up a form so you can contribute your events and over time grow it into something that captures what it is that we've done over the years. Perhaps it will grow into a section on Wikipedia, perhaps it will become its own thing, it's too early to tell.

    As I've said many times, if you didn't write it down, it didn't happen. So, this is me, or us, writing it down. Perhaps we'll be able to find a way to make it through the next 100 years.

    You can find the Amateur History Project under Projects on my home-page at vk6flab.com - I look forward to reading your contributions.

    So, thank you Christine, VK6ZLZ for pushing that sheaf of paper into my hands. I hope I'm worthy of the history that it represents.

    Foundations of Amateur Radio To get into the hobby of amateur radio is easy, but that doesn't mean it's simple. I was introduced to the hobby three times. The first time I was a Sea Scout in the Netherlands. It was JOTA, the annual Jamboree On The Air and radio amateurs across the planet were set up at various Scouting locations with their stations showing off how to make contact with far away places. My memory of it is brief. I recall a green heavy army tent with radios on a table. There was noise everywhere. I was told that I was hearing a station in Brazil, which seemed incongruous, given that I was standing on an island surrounded by other Sea Scouts, a place where I had been camping and sailing for several years. We trooped out of the tent and ten minutes later I broke a finger playing a game where you sat on a mast trying to upend the other person using a canvas bag with a jib in it. I was unceremoniously upended and landed poorly and broke the middle finger on my right hand. Being a teenager that was of course a source of immediate ridicule and innuendo and getting a dink, that's Aussie slang for getting a ride on the back of the pushbike of my boatswain to the local hospital, after rowing from the island to the mainland caused me to completely forget that amateur radio experience. The second time I came across the hobby was through my then manager, Ian, whom I now know as VK6KIH, but at the time he was a quiet spoken man thrust into the role of manager. The introduction came in the form of a Daihatsu Charade with a massive, what I suspect, was a 40m HF whip. The amateur radio aspect made little or no impression. The antenna, clearly much too large for such a tiny vehicle, did. I don't recall ever talking about amateur radio or even seeing his setup. Come to think of it, I'm not sure if I ever have. The third time I came across the hobby was at a dinner table surrounded by fellow "dogcow" geeks. One of them, Meg, then with the callsign VK6LUX showed us her brand new shiny purchase, a drone, that could be controlled remotely via WiFi on 2.4 GHz. She went on to tell us that the range was pretty limited because it was WiFi, but because she was a radio amateur, she was going to experiment with an amplifier. This was permitted because as I learnt, the 2.4 GHz WiFi frequencies are shared with amateur radio. You might know it as the 13cm band. I asked about this thing called amateur radio. I wanted to know what was involved, how would you become one, what would it cost, you know, all the things everyone always asks. I was told that there'd be a course in two weeks with an exam the weekend after. I asked if we needed a group booking and was told to "just rock up". So I did. I got my license in 2010 and my world changed forever. I will add, just to make sure that if you're planning to do this, that during my course I discovered that my license wouldn't permit my use of the 13cm band, so I'd have to upgrade. I promptly purchased the requisite course material and started reading. In the mean time I got distracted by the activities at a local club, then I bought a radio, then I was told I wasn't a real amateur because I only had a beginners' license, so to prove a point, I started having fun with my license. I haven't stopped since. Now, some, or maybe all of this, I've shared before. Here's something new. I'm a so-called A.F.O.L, or an Adult Fan Of Lego. It's not a guilty pleasure, I'm happy to admit it. I have too much Lego around me. My oldest set is from 1964, House with Garage, number 324-2. It's not complete any longer, the car is long gone, the garage door weights are broken off, but it has pride of place in my living room. History does not reveal how I came into possession of it. Best I can reconstruct is that in the deep dark corners of Australia it takes a little while for kits to arrive, since I was born after the kit came into existence. I do know that I had it before 1976. The other day I was watching a documentary about Lego and one thing stood out to me. I'll share the entire quote by Kjeld Kirk Kristiansen the then President and CEO of The Lego Group: "During the 1990s, we kept thinking that much more should be done for the adult "hobbyist builders," as we called them at the time. Most people on the management team thought we should concentrate on children instead, but I felt that a person could have an inner child at any age." Why this is important is because of my activities as a radio amateur. We as a community keep saying that we should grow, that we're losing too many people, that we need to engage with S.T.E.M., or Science, Technology, Engineering and Mathematics. Whilst that may be true and whilst JOTA and Scouting might give us exposure to fresh new people, there's a massive community of adults who already know about our hobby. They just don't yet know how it might interact with them, personally, or how they might find it interesting, or engaging, rewarding, and all the...

  • Keep It Simple Stupid

    Foundations of Amateur Radio

    The other day I lamented to a fellow amateur that my shack was not functioning well. Specifically, my main workstation died three months ago and ever since I've been struggling to reclaim my productivity. One aspect of that is my desk. For half a decade or so I've had my computer clamped to a rolling lectern. It allowed me to move around my office as my mood and the light from the window changed.

    During the weekly net I'd move my lectern and computer next to my radio and host the net whilst logging on my computer.

    That's no longer possible because of a number of reasons, so instead I was trying to accomplish the same thing on a tiny 13 inch screen which didn't work for me. My friend asked me why I hadn't just extended the microphone lead from my radio, so I could sit at my now stationary computer and still key the microphone. I located an Ethernet joiner, an Ethernet cable and did just that. Simple. Job done.

    Then I started wondering why I wasn't on HF with my station and if there was a simple solution that was eluding me. Spoiler alert, it still eludes me. The requirements are not too complicated, well at least in my mind they're not.

    I want to operate on HF. I want the computer to not be physically, or specifically, electrically connected to the radio, in any way. I need to be able to use logging software that tracks the radio band, mode and frequency. I'd like to use digital modes, I'd like to have a computer controlled voice keyer and I do not want to run Windows and if I can at all help it, I'd like to spend as little time as possible doing this without spending an arm and a leg.

    So, then I started wondering what this looks like for other people. What kinds of compromises have you made in your shack? What have you accomplished and how did you get there? What choices of hardware and software did you make, and why? Did you give up, or face the challenge head on? How did you gather information and how did you find out what others did?

    Not for a moment do I think that this is a simple thing to solve, but it's clear to me that I'm so far down the complicated rabbit hole that I'd like someone to show me the light at the end of the tunnel to make some progress.

    Of course I've not been idle while all this is happening. I configured a Raspberry Pi, a small single board computer, to talk to my radio via USB. I connected a sound card to the audio connector on my radio. Theoretically this should give me all that I need, but the difference between theory and practice is common knowledge, in theory it works, in practice it doesn't. The Pi is a few years old, but it's not doing much at all. It connects to my network wirelessly, so my main computer isn't physically connected to the radio, but it's still pretty unreliable and I have to say, calling CQ, either using voice or digital modes, should be rock solid. You don't want your radio to keep transmitting after it's supposed to and other little issues like that.

    So, how did you do this? I'm interested to know. I'm not the first person to run into this issue and I'm not the last. Your experience might help me and it might help others. Drop me an email, cq@vk6flab.com and I look forward to hearing about your adventures.
