GTX GTX GTX - PL/DPL/CSQ Detect Where ?

Post by USGOVTECH »

I need to interface a GTX to a repeater controller for an auxiliary receiver set up. I need a logic signal either active low or active high (COR/COS) where in the radio can I get these signals ?

On the Spectra the LED only indicates squelch has been broken not CTCSS or DPL. If the mtx is anything like the spectra the audio PA has an enable line which is essentially COS (code/tone decode AND squelch). This is pin 10 on the audio PA module on the spectra.
