As a good starting place, I'd recommend the American Radio Relay League (ARRL) "Radio Amateur's Handbook". that is certainly the convential approach, but something like the new motorola single chipper which has just enough dsp umph to work on audio would work very nicely, too (as long as you are trying to modulate two audio signals, not one audio and one rf). -- REALLY, instead of hyping low impact soles, I think what we need are more low impact souls.
