Maratracs do not have that connector.

Most everyone uses the MIC HI line and the stock preemph/limiter and have excellent TX audio.

If you must have "flat audio", input to pin 6 U651A thru a 220 K resistor and a coupling cap. This still goes thru the deviation limiter stage.

External TX PL tone can be inputed to pin 13 of the interconnect, P6. Use a 4.7k series resistor and a coupling cap.
