[Elecraft] K2 assy: oops: threw out xtal filter bag with alignment# on it

[W3FPR - Don Wilhelm]

Andrew,

It might make a small difference, but you can work around it - assume the
crystal set is 3.7 (the most common) and set the BFO frequencies initially
from that setting. - Those values will work but possibly will not be
optimum.  After you have a functioning receiver, you can use Spectrogram to
set the BFO frequencies so that the center of the passband is at your chosen
sidtone pitch and all will be well.  See my website www.qsl.net/w3fpr
article - Step 3 of K2 Dial Calibration for detailed information on setting
the filters and associated BFOs.
