update on this thread.i acquired recently a milspec ptt.i dont know if its modified or not but i saw a small capacitor and a resistor in it.when i first fielded my comms combo ( authentic swimmer headset,milspec ptt and tri 152 radio it was all working.until recently i had no mic function and was only able to receive transmission from an frs radio.how do i fix the ptt to make it function again?
