The OP said cost was important and that he was a software geek rather than a RF geek. Can you re-transmit on a nearby frequency without blasting the receiver off the air? There are low cost chips that send digital (RS-232 bandwidth) signals over ISM bands. Are there similar chips that send an analog signal such that "phase" would be a sensible term? -- These are my opinions.
