[Milsurplus] BC-221 with noisy tuning

[Glen Zook]

Similar on various versions of the LM- series.  Some models have a trimmer on the crystal and some don't.  I added it to my LM-7 to improve the accuracy.  Just required a ceramic trimmer.

I assumed this was a ham mod because someone has stuck a
paper label on the front of the nomenclature plate. Perhaps an
over-hasty assumption!

The crystal trimmer behind the name plate may have been a modification at
one point in the production cycle, but they were a standard factory item in
all the versions I have seen.
