There are several possibilities on this kind of problem.

Some things to try:

1. Put one or more snap-on ferrites on the coax. You may have an "RF
in the shack" problem which is feeding back into the mike circuit. If
this fixes it, you have an antenna problem, most likely a poor, i.e.
non-resonant ground.

2. Add some more coax and get the TX farther away from the antenna.

3. Try it on a dummy load. Is the squeal still there? If so, a
possible power supply problem.

Good luck.
