[Elecraft] Cal Fil possibilities in the K2

[Don Wilhelm]

Peter,

Tom (N0SS) gave you a correct answer, so all I can do is to say part of it
in another way.

When you are set up with Spectogram, position both the CW and CW REV BFOs to
center the passband around your the sidetone frequency that you have chosen.
Note that CW and CW REV are similar to LSB and USB - in other words,  the CW
BFO will be on the lower side of the passband while the CW REV BFO will be
on the upper side of the passband.  You will not see it that way in the
Spectogram display unless you look carefully - the passband should flip
around the center frequency when you get it right (i.e. the audio
frequencies below the filter center in CW mode will become the frequencies
above the filter center in CW REV)  If the filter shape were perfectly
symetrical you would not be able to see it at all, but if you look closely
at the slightly jagged edges on the filter slope, you can see the effect.

73,
Don
