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.
