I really don't consider a very slight adjustment to the shortwave frequency
every once in a while to be a big deal. For example, listening to the BBC
last evening, on 5975, after an hour or so, the display showed 5974. That's
the kind of drifting we're talking about.

This is perhaps a difference due to frequency range or manufacturing
variation, but if that was the kind of drift I was seeing I would have
never brought it up. The last couple nights I've been listening to R.
Australia on 9580. I tune it so the signal is maxed and the display
reads 9580. A couple minutes later (and I really do mean a couple
minutes), the display reads 9578. This, I assume, is due to tension
in the tuning mechanism. I re-tune to 9580. Five minutes later it
reads 9579. I, again, attribute this to mechanical tension. I re-tune
to 9580. Five minutes later it's back to 9579. Re-tune to 9580. I
start reading while I'm listening and stop paying close attention to
the display. Maybe fifteen minutes later I'm hearing a fair amount of
static and it's clear the radio has drifted again. The display reads
9578. Re-tune to 9580. Fifteen minutes later it's at 9579 again. It
did seem to become more stable at this point.
