FW: [Elecraft] Rig drift

WHOA! there.

The filters drift right along with everything else. You don't have to touch
them. If they are drifting independently, that a WHOLE 'nuther story.

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.
