Re: Cw Signal Shift with Filter Change

Is this something that just happened, or has it possibly always been
there unnoticed?  In any case, a change to the BFO frequency of one or
all filters is in order.

The condition should be cured by doing a filter alignment.  I highly
recommend using Spectrogram to do that task.  See my website
www.w3fpr.com - article on K2 Dial Calibration, the filter alignment
info is in part 3 of that article.
