RE K2 Bar Graph Erratic

Elecraft mailing list
 Robie,
My K2 had the same problem that you described after a long period of not being used.  After severaldays of being left powered on  and daily use, the problem went away.
My theory is that bypass capacitors in the K2 may have "reformed" and eliminatednoise in some circuit that was affecting the S meter bar graph.
As Don says, it could also  be a noisy RF gain pot.

Even though the K2 is a dated design it is still a great rig. I would never part with mine.
