I need an indication that PTT is active from the XPR4000 radio, preferably via the rear accessory connector to operate a muting circuit.
First thought is to probe the rear PTT input and hope that it mirrors the state of the Mic PTT.
Internal modification of the radio is NOT allowed so I will not be looking at monitoring the state of the TX LED on the front panel.
Has anyone done this?
