Use a diode from the white wire to feed a buffer that will actually short the center of a power divider resistor pair in series with the ctcss into the exciter/modulator - this needs to hold low except when the correct pl is heard, when pl drifts away or the user unkeys the outbound pl will be turned off instantly - the only side effect is no reverse burst.
