[Elecraft] L-34 Tuning Adjustment on K-2

Thu Jan 3 20:53:01 2002

I'd suggest you do the second crystal filter modification, which allows
for a more optimal setting of L34 for CW while better equalizing USB and
LSB center pitch. From my initial experiments with this mod, I recall
that the peak is more defined as well.

Sorry to leave off your name or call, but you didn't supply it!
