Batboard

Hi,

I am putting up a simple repeater, will be using GP300 as the RX.
Can somebody tell me where to tap the 'COR' on the PCB, would really like to use it.

As mentioned in an earlier post, to tap the voltage from the top speaker outlet , what will be the circuit diagram to give a clean audio to the MIC in of the TX.

Thanks in advance and in anticipation.

The GP300 transceiver was used as the transmitter and another one for the receiver in several low power repeaters.
One, the SysTel, is a good example.

There is not a COS, but there is switched DC from the bridged audio amplifier driving the speaker, both sides of the speaker float..
Let's call that RUS, receiver unsquelch that can include proper PL/DPL detect also. The voltage goes to about 3.4 volts.

Thanks Will ,
I am also in need of a simple circuit by which audio from the GP300 can be fed to the TX Mic in.
Hope somebody can help me in this.

Regards
Bijoy
