This is what I'm thinking:
Code: Select all
Pin 1 Ground. Only one needed, disable pin from radio 2 cable.
Pin 2 Mobile transmit audio. Radio 1 only, disable pin from radio 2 cable.
Pin 3 Enable / disable VRS -- disable both; using switch
Pin 4 Mobile PTT output. To Radio 1 only, disable pin from radio 2 cable.
Pin 5 12v input. Only one needed, disable pin from radio 2 cable.
Pin 6 Mobile receive audio. Combine both pins from radios 1 & 2.
Pin 7 Mobile COR Detect. Combine both pins from radios 1 & 2.
Pin 8 Local mic audio. Not needed, disable both pins from radios 1 & 2.
Pin 9 On Air Detect. Not needed, disable both pins from radios 1 & 2.
