Mine was like that a long while ago also. If I pressed it inwards while
slightly rotating it, it was OK. I remember reading in the archives that it
probably needed replacement, but thought that I had nothing to lose by
spraying it with contact spray.  The spray solved the problem and has done
so for probably a couple of years and at least 1500 QSOs. If you want to try
this then the front panel needs to be removed to access the pot.
