A mate did that bit - CM108 I think.

lol - great question. I was very excited at the start and did things like talk to a guy in Spain with 5W and a long bit of wire out in the bush, talked to people 400 km away by pointing a handheld antenna directly at a satellite as it passed overhead, received images directly from the amateur station on the ISS, met a heap of smart old guys who were doing interesting things with radio - designing antennas, setting up repeater networks etc. I went in a couple of competitions (in ham radio this is usually about how many contacts you can make over a time period). But ultimately, it turns out I like interesting technical problems, learning things, and buying stuff I don't need off the internet - more than chatting to people I don't know. So now I'm more into Linux and self-hosting which scratches a lot of those same itches.

I still have a short range radio in the car and a couple of handheld radios. With these I can key into that Raspberry Pi, have the audio travel over the internet and pop out anywhere in the world there's another AllStar point and go over the air to radios there, but I've sold all my HF gear (that allows you to talk direct to anywhere without infrastructure).

It is an interesting, and quite diverse hobby, and there's a lot of cheap Chinese radios, and a bottom tier license in most countries that's easy to obtain (for example without learning Morse code). I'd recommend it to people interested in tech stuff. It's a hobby that might not exist in 50 years - a lot of the radio spectrum allocated to ham radio in the old days was considered worthless, but now governments regard that as a valuable public asset that can be sold to telecommunication companies. Also there's growing interference from digital gadgets and wireless devices that requires innovative solutions to overcome.
