There was a thread on this just recently here. I just got the radio-man (AM/FM) today and it's decent, easy to learn the protocol if you want to do your own thing, and the software that comes with it works with XP.
Sure. Here's a screenshot. It's old Windows 95 software and still works. Amazing! Well, the mute and volume controls don't work very well but that's probably an XP thing. The sound isn't the best, but I'm in the basement and picking up quite a few stations so I figure it will be great in the car. It's powered off the serial port and I'm sure the RTS line has to be high. Not sure about DTR. Anyway, I think a USB adapter would work as long as it doesn't take more than the max USB power requirements.
Ooh, no. Try looking at the picture on your touchscreen. It's pretty hard to hit some of the buttons like tune and scan, but I'm sure there will be more software available for it soon. Want pics of the guts? There's a big chunk of steel in it for weight and let's see... a PIC16C56-XT/50, Sony CXA1238M, 2614FS and an AM coil. I'll be doing a USB mod on it tonight I think.
Yep. I chopped up a USB cell phone data cable I had laying around, but now I can't figure out how to connect it. As far as I can tell it doesn't pull much power though so it should be good for a serial-USB thing.
