Wired backwards
the mic is the that came with radio,I get sound only after key the mic
have the same idea with Laron and Walker...that the microphone may be wrongly wired. Have the pin opened and play around with the wiring therein to identify the receiving and transmission wires. When got it correct, you will hear sound when not keying and able to transmit when press on the PTT button.

I would assume you have wired it incorrectly or have tried another 4 pin mic such as an midland which are wire differently for the galaxy, ranger, connex, cobra an undien 4 pin mics. Galaxy Radios DX959 MOSFET Final Service Manual

Hi Anonymous, I want to help you with your question, but I need more information from you. Can you please add details in the comment box? --Is the mic comes with the radio or a new one? --Do you hear the sound only when you press the mic and once you release it's off again?
