To all who replied - thank you.
I guess I probably knew this, but just couldn't quite get my aging head
around it. I think I was considering the CW filters as just an extension of
the SSB filters without realizing that in changing to CW I was shifting the
passband from the carrier frequency by the amount of my sidetone.
I guess if I set my sidetone to 0 Hz, there would be no shift - and that
makes everything make sense.

Tom,
It should shift exactly by the amount of your sidetone pitch. That is the
way the CW offset works - there is no offset on LSB or USB, but CW is offset
so you can read the frequency of the signal on the K2 display, but be able
to hear it by placing the BFO off to one side or the other by the amount of
the sidetone pitch...
