The shafts on those controls can become worn where the shaft exits the
body of the control, and that will allow an excessive amount of 'wobble'
in the shaft and knob. The solution is to replace the controls. The
VFO pot was improved a year or so ago, so if you have to older one with
the blue body, the new one will be better and last a lot longer.
Another temporary solution is to remove the knobs and add some sort of
washer (like a properly sized O-ring) between the panel and the knob.

I have been using my K1 mobile for about a year and a half now, and am noticing
that the 3 main controls - volume, RIT/XIT, and the main tuning control are now
fairly loose and wiggle about a bit when I am operating them. They don't seem to
be moving together like the circuit board that they are mounted on is loose, but
I may be wrong on that. Any ideas on tightening them up? I did not build this
radio, so I am not too familiar with what goes on inside it yet.
