[android-developers] Re: android's radio transmitter API?

Stop and think a second about the problem from a non-technical
standpoint.

It takes governmental approval to market a transmitter -- and often
even to operate one.

While there are bands in which unlicensed devices can operate,
marketing devices in those bands still requires certification they
only operate in those bands!

So even if *technically feasible* to give your device this sort of
control, I'm pretty sure any settings that might control it are
restricted by the radio firmware. I can't see them getting approval
otherwise. I don't know of any device which has gotten approval where
remaining within the proper band depended on *unlicensed users*
operating it within the proper band.

Receivers are another matter entirely. I upgraded my Nexus One, and
got an FM radio in the bargain. Software Defined Radio (SDR) is a cool
technology!

I've heard of people extracting the chip and playing with it, but
that's definitely the hard way to go. You can get Software Defined
Radio boards, and pair them with the phone (perhaps even "pair" as in
"bluetooth"). Google "Software Defined Radio" and "Nexus One" or
"Android", and you'll find a lot of interesting links and projects.
