If 'IF Shift' is not useful for CW, then the K2 has something better
than IF Shift already. Set up the SSB FL2 thru FL4 filters carefully so
that FL2 is more narrow than FL1 (the OP1 filter), then FL3 is about 200
Hz more narrow than FL2, and FL4 is even more narrow than FL3.
Use Spectrogram (or equal) to determine the actual filter width - the
numbers displayed on the K2 will not be correct for these wide filters, and
set the low frequency corner of the passband at 300 Hz for all the filters.
Spectrogram will show the proper passband positioning.
I did this and then found myself an AM BC station and tweaked the
filters for best intelligibility. I've been very pleased with the
results!
