This processor controls the 2m and 70cm transceivers. There are two radios.
Each consist of one COMM processor, one 2m transceiver and on 70cm transcevier.
A static network of gates takes care of assigning radios to MPU and CRX.
+ Optional: connect the "soundcard"(IDM) output to the audio input of the 2m transceiver
+ to send out audio.
Tasks:
- initialize and control the 2m and 70cm transceivers
