Wiring

In order to determine which UART commands needed to be sent to the radio, and how the radio responds, I used a Bus Pirate by Dangerous Prototypes
I also built a small Cat5 cable breakout that split the cable between the radio and microphone, and allowed me to probe it while it was in operation.

Microphone to Radio

Notes

• A single 0x06 packet is sent approximately once per second by the microphone to the radio as a type of keepalive
