[Elecraft] Rig drift

[Ron D'Eau Claire]

If you use RIT or, as I prefer, SPLIT, then you just tune to put the
signal in the center of the IF bandpass without changing the xmit
frequency. There should be no reason to shut down and recalibrate even
if it is drifting. That's what I do if I sit down to a cold rig. Of
course, it isn't even apparent unless I am using an IF selectivity of
less than 400 Hz. 

It does sound like you have an excessive amount of drift, Earl. I can't
speak from experience because my K2 sits in a shack where the
temperature extremes are about 50 to 80F (10 to 27C).

==========================================================

As I mentioned, I can live with the VFO frequency drift with
temperature, but I cannot take time out during contests to periodically
recalibrate the xtal filters using Spectrogram, which is necessary to
keep the received signal within the narrow cw filter bandpass even
during slow temperature changes.

That is the intolerable part of it.
