ppl have been talking abt this subject for a while, but so far it's looking
like IR might be easier/better. Just for S&G, I had been looking through
Popular Electonics magazine, and they have those little (smaller than a
dime) spy FM transmitters. Supposed to TX to an unused (normally) freq on
the FM band. RX hardware isn't too different from TX hardware. What you
modulate, you must demodulate. About the only big difference is the
amplifier in the Rxvr. Well, just in case nobody had thought about those
little spy transmitters yet.
