You need to check the Microphone setting in Skype.
Open Skype, Click on Tools - Audio Settings, then in Microphone settings click the down arrow and select the built-in microphone then save the settings.
If the microphone you selected doesn't work then select a different one.

I have feedback when transmitting

Check your audio settings. Feedback is a condition caused when you are transmitting and your audio is coming out of a speaker (headphone) and is picked up by the microphone. Try turning your audio down; reducing your microphone gain; and perhaps using a wind sock (microphone cover) over your microphone to reduce the amount of feedback audio entering into the microphone (manual pg 13).

Trying to determine the cause of intermittent signal from microphone on a vx 4600 radio

Yes, short or lack of a good ground. It could also be the cord attached to the mic. The mic itself should provide the needed feedback to the radio that a mic is plugged in. Do you have anything connected to the accessory jack in the back of the radio? That can cause the same issue.

hello there,
Well you have not supplied much information-------- How ever I will give it ago, it seems as if you have a microphone problem. If you have two such radios do the Microphones unplug from the actual Radio, if so interchange them and see if the other Radio produces the same sympton then it's probable it is in the Microphone! If you cannot exchange microphone as I suggest I am afraid it will need servicing by some one confident to carry it out.
Best of luck,
