GE EXEC II Configuration
To modify the radio for full-duplex (repeater) operation, follow these steps:
1. Remove Q905 and Q908 on the System Audio Squelch board (SAS board).
2. Install a wire jumper from the Q908 emitter solder pad to the Q908 collector solder pad.
3. Care should be taken not to damage the transmitter PA due to continuous duty operation.
