Thanks Scott. I will wire the 13.8v to the volume to turn her on and off. So you think the two yellowish orange black push button wires can't be wired to the mic pins of the radio to prekey up for me automatically while keying the mic?

thundir

Hi Scott, Thanks for the response.There is 3 wires. at the bottom end. (1)Red wire to 13.8 voltage source. (2)Black to ground. and (3) blue wire to mic audio wire. This leaves me to the 2 wires at the switch. Couldnt I just disconnect the switch and connect one end of the wire to the TX side of pins...
