[Elecraft] Cal Fil possibilities in the K2

[Peter Lutz AA6AV]

Gang,
Since I now have all the options of interest in my K2, I want to make sure
the filter calibrations are "correct", or at least as good as can be.  I have
been experimenting with Spectrogram, following the approved documentation, 
but I still have problems.  It appears that there are two adjustments
available for each filter position.  I can set the width and the BFO
frequency.  But I seem to be missing something when it comes to setting
the position of the dial frequency when I change modes.  Should a clean,
centered CW signal remain centered in the bandpass when I switch from
CW to CW Rev.?  I loose the signal completely and have to re-tune quite
a bit to find the signal again.  Should it work this way, or do I have
something badly out of adjustment?
To put it another way, can I adjust the filter width, BFO frequency, and
center frequency of each mode the way I want all at the same time?
