[Elecraft] noisy VFO's

[Pete Smith]

Recently, my VFOA knob got a little wobbly, and then it started dragging 
heavily, only when turned clockwise.  I took the knob off and discovered 
that the top one of the two control nuts had worked loose entirely, and 
the bottom one was loose.  Tightened them back up and readjusted the 
drag, and everything was fine again.  Perhaps yours is another variation 
on this theme.
