[Elecraft] Realign xtal filter for changed sidetone frequency?

[Sverre Holm]

Thanks for answers. I guess the reason why you have to realign the BFO
settings is that the K2 processor only stores BFO D/A values (0...255)
for the varicaps, not the actual frequencies, so it has no way of
knowing how to add/subtract frequencies.

I envy those of you who can realign those filters quickly and accurately
though. This is the one single issue with the K2 that I never seem to
get comfortable with. I have tried Spectogram and other methods. My
filters may be fine when aligned, but I get the feeling that they drift
out of tune after a while - even after I installed the reduced
drift-modification for the BFO.
