[Kenwood] TS-950SDX ATU Squeal

Darrell, I have the same problem and it is intermittent. The tuner tunes
properly but many times lets out the squeal when tuning or changing bands.
It sounds like a coupling slipping. I took the tuner out once and tried to
see if I could get at a shaft coupling with no success. Let me know if you
find an answer.
