I have a pair of 6 or 7 year old T7400's single pin radios and the problem I'm having is with my headsets. I have a Devgru Swimmer and Bravo Comtac II with PTT.
I plug them into the radio but they don;t work. I looked at the manuals and did as they said but the radios go to VOX operation.
My question is am I missing something in the menu somewhere or is it time to by a new radio?
