[Elecraft] K2 drift

[Bernie KF0QS]

Dear OM's and YL's:

Twice, I've had people tell me my K2 (which I've had on the air for over 3
years) drifts a bit in frequency.  Both times have occurred during long
QSO's so it appears to be a slight drift.

This phenomenon may also explain something else that happens.  Whenever I
set up the filter settings, they work well for a while.  After a while, the
sweet spot (i.e., the point at which the heard signal is in the middle of
the filter bandpass) seems to migrate eventually to about 1khz below
wherever I set it (at least that's where I have to move the RIT to hear the
signal when I switch in the filters).  

Is there a common fix for both these problems, or am I experiencing two
different things.  Any help you can give would be appreciated.

73 de Bernie, KF0QS
