What's the easiest (cheap, few components, including a uP is OK) way to hook a microphone to a serial radio transmitter (like the Maxstream Xbee) and send low-quality voice audio?
=========================================== Military SINCGARS radios use 16 Kbit Continuously Variable Slope Delta Modulation. So your radios need to handle 2K bytes/sec to transmit voice using this technique.
