Do I have the operation of the microphone correct? There are 3 connections on your microphone.


-The tip contact is for push to talk. This is a power line. When grounded tells transmitter relay inside radio to switch from receive to transmit. The microphone diaphragm also uses this power.
-The middle contact (ring) is the audio out and is sent to the pre amplifier in the radio which is voice we here on the other end
-The base or(sleeve) contact is ground used by microphone and is the ground for the push to talk switch that activates the transmit relay in radio


So if I am sending a signal out with no voice that means there is bad connection in the middle or (ring) contact or wiring?
