I'm a Ham radio operator, and interested in building my own real 2m/70cm transceiver that I can put in my car, complete with a little display to impress my friends and such. So these Pi articles interest me, but I'm more interested in interfacing a microcontroller to a real quality transmitter that can operate at, say, 25+ watts.<p>Ideally I'd like for this project to run Android, and drive my car stereo too, and do a bunch of other crazy things like GPS.<p>There's surprisingly little information out there on how to approach such a project. I've looked for components I could use on Sparkfun, and there's not really anything that jumps out at me, for either building 2m/70cm transceivers, or even for doing the stereo amplifier part.<p>I did find this fascinating article, though: <a href="http://hackaday.com/2013/02/28/hacking-a-ham-radio/" rel="nofollow">http://hackaday.com/2013/02/28/hacking-a-ham-radio/</a>
