Wiring a cb or ham radio microphone?

Hi. I've constructed a 40 metre transceiver. The mike wiring diagram shows ( mic signal / mic ground /ptt / ptt ground).  Can anyone tell me the correlation with  (common / rx / tx / audio)
Thanks Ken

Since you haven't gotten an amateur radio guru here, Google for amateur radio or amateur radio microphone and contact your local amateur radio club or one of the amateur radio web sites like this one http://mds975.co.uk/Content/amateur_radio_projects....

Sorry I should have been more specific it was built from a kit.

Passed my Foundation test last week and waiting on acknowledgement.

without seeing a cct diagram I am guessing:

Common = ground

audio= mic signal


rx = no idea.

It may be that the plug expects you to use a headset/Mic so the rx is the audio feed for the headset. The talk may be VOX controlled.

I assume you know the laws about transmitting?

Err, you say, you constructed it. Just have a look in your build-documentation. Hope, you documented any step of your design process.
