Thanks to all who responded. The "haunting" is now over. I adjusted
the VFO knob to put a bit more pressure on the felt washer and now it
stays put when I turn loose of the knob.

Good afternoon,
Now that I have your attention, I don't really think that my K2 is
haunted, but it does seem to want to tune itself.
As I tune the knob up and down the bands and come to the frequency that
I want to listen or transmit on, I stop turning the knob and I take my
hand off. The knob is fully stopped when I do this. As I watch the
readout after taking my hand off, the frequency starts to change slowly,
sometimes adding (or subtracting) as much as 80 hz to the frequency at
which I stopped the knob. The knob is actually turning by itself. It
may go either direction and seems not to be correlated to whichever
direction of rotation I was using when I stopped turning.
I have been using the K2 regularly on the HF bands only for the past few
weeks. Since building the unit last spring, I have used it mainly as an
IF rig on the microwave bands. Until the last day or two, I haven't
noticed the "self tuning" feature.
Perhaps this phenominom has been previously noted and a fix found. I
cheerfully admit that I haven't done any research in the Elecraft
Archives.
So....what say ye about this?
Dave, K4TO
