Foundations of Amateur Radio #140 – How should I promote my contest?

The act of telling someone about something is promoting it, not in a marketing sense, just an awareness sense. The act of not telling someone is keeping a secret.

Radio amateurs, and I have no doubt, people who are not, like to plan things. They set-up contests, on-air activities, organise swap-meets, build websites, write articles, invent things, build stuff, and all manner of other amazing activities. Some amateurs talk about what they’ve been up to, but most just sit quietly, hoping that their brilliance will be discovered by someone.

Of course that rarely happens.

Let’s imagine a contest. It’s an activity that you’d ideally want other amateurs to participate in, talking to yourself, on your own is like being a broadcaster and I can tell you, that’s a tough gig. A contest is about making contacts between different participating people.

So, your contest, it’s going to have rules, a planned outcome, say more QRP activity on 40m, and it’s going to run at a particular time. I’ve lost count of the times where that’s the sum-total of effort put into organising a contest. Of course the contest flops, since no-one knew about it, and often that’s the end of it.

So, what can you do to actually get a head start in making this contest work?

For starters, you should figure out who the audience for this contest is. If you set it up on 160m and aim for beginners you’ll have a problem, since they’re not allowed on that band. So, the audience is based on the rules of the contest and of course one influences the other.

Once you’ve got a defined audience, and no, all the amateurs on the planet is not a valid audience, since by that metric you could also say all the taxi-drivers in New York city, and while that is a defined group, it’s unlikely that (more…)

Foundations of Amateur Radio #139 – Antenna gain and polar chart magic

If you’ve ever been on the hunt for an antenna, and let’s face it, in amateur radio that’s pretty likely, you’ll get information about the gain of an antenna. Often someone will tell you that this one has 12 dB gain, versus that one which only has 9 dB.

As an aside, I’ve seen a few videos where people are comparing sound levels and mention that without the fan, there is only 3 dB less noise. What they don’t realise is that 3 dB means HALF the noise.

The same is true with an antenna. That 9 dB antenna has half the gain of a 12 dB antenna.

In the past I’ve talked about gain. It’s always in comparison to something else. If I say “that antenna has 12 dB gain”, I’m actually saying: “that antenna has 12 dB gain when compared with an isotropic source”. To jog your memory, an isotropic source is a theoretical source of electromagnetic radiation. It cannot actually exist. It radiates uniformly in all directions.

Now when we talk about gain, we’re saying that our new funky antenna radiates better in some or other direction than an isotropic source.

As a consequence of this, it also means that it radiates worse in other directions.

So antenna gain is a trade-off between radiating everywhere like an isotropic source, and only radiating in one direction like a laser beam. As an aside, a laser beam could be seen as an antenna for light. It radiates much better in one direction than in any other, and given that light is also an electromagnetic radiation, we’re still playing in the same area of physics. (more…)

Wireless Institute of Australia Seeks Amateur Radio Power Increase

Foundations of Amateur Radio – Episode 137 Virtual Radio

There is a feeling of anticipation in the air, the year has started, there are so many different ideas bubbling through my mind that I feel like an excited puppy dog wagging its tail.

I’ve been playing with a wonderful piece of software called GNU Radio, more on that in a moment.

So, I have for a while been dissatisfied with the offerings of SDR software. There is lots of development going on, lots of new toys being invented and many different hives of activity in this area.

It’s not unlike the progression from reel-to-reel based radio broadcasting via VHS tape, to computers with audio files. There are lots of solutions solving specific problems, but there are also a group of solutions looking for a problem and only time will sift out which one is worth the effort.

In amateur radio we deal with valves, resistors, capacitors, inductors, transistors, integrated circuits, crystals, connectors, solder and many, many different physical things.

I’m a computer guy, have been since I was in primary school. I grok computers, more-so than any aspect of anything else. Amateur radio was intended as an escape from this world, but initially to my dismay, but now to my delight, computers are making serious inroads into the hobby. Not just as peripherals that take care of logging, messaging, propagation forecasting and the like, but as integral parts of the radio. (more…)
