[Elecraft] [K2]K2 filters continue to "drift" out of alignment

[K1FFX]

I thought I would close the loop on this issue.

It turned out that my "fix" last Fall was just a partial or temporary fix
and the BFO did, in fact, continue to drift.  So, I finally went ahead and
did the procedure which you recommended, which I hesitated to do at the
time.  I removed L33 and reflowed the solder for the two BFO crystals.  It
turned out that removing L33 was actually straight-forward ... or maybe I'm
just getting better at this.  It just took good magnifiers and a little
patience.

In any case, this seems to have fixed the problem.  The "center frequencies"
moved back to about where they were when I first built the K2 and receiver
performance has been restored.

Thanks again for the advice.

Best -
