Question about this mode.. 3 = full-duplex mode, without repeated audio from main input source when trying out this mode it appears to still TX on the main Input source. We have this connected to our vx7000 repeater and We want full duplex coming in all the time and I think this is the mode i need but when i set it to this it still tx's on main audio input. We want full duplex audio coming in even if the repeater is TXing so we can hang up on a autopatch call if the repeater is in TX mode.. Any thoughts on why duplex =3 still Tx's on main audio input?
