It's the lie detector going off.

Are you running an external speaker? How high is your mic gain? Have you checked your coax connections? What kind of Coax are you using? Are you using talkback?

There are a lot of good things in life to pinch......
Coax isn't one of them.

Is the coax damaged because of this pinch? If it was pinched to the point of it affecting the transmission I would think about getting another piece of coax. Just to be on the safe side..Or have someone check your SWR and make sure it is in an acceptable range. Even though its not squealing anymore there could be some internal damage that could have a bad end result to your radio.
