Re: 4 pin microphone cobra

 

Rx isnt needed as the radio receives with the n ed for any special mic connections ,? braid is common, You then have the transmit wire and the audio wire , Audio wire is normally inside the braid so as to shield it , You may need to put a capacitor in series with the audio wire to block DC .
