Perhaps the enhancement could be a BFO that is adjusted by a front panel
control?
This would be nice, and I presume that you mean that the knob would
maintain the location of the BFO in relation to the passband along with
the sidetone pitch. Currently it's possible to adjust the pitch from the
menu (although this is not a one-knob operation!), but in order to keep
the selected pitch inside a narrow passband, you need to do the CAL FIL
procedure.
So the knob that you refer to would have to cause the microprocessor to
recalculate the VCO offset that is used to place the selected pitch at a
given location in the filter passband. This is what happens when you run
CAL FIL.
This is the one feature that I really wish the K2 had. My TS-940 and
756-ProIII both have this, and I find it very helpful. It's not only nice
to be able to customize the sidetone pitch, but I like to tweak it easily
via a front-panel knob every so often during long operating periods, like
contests - adjusting the sidetone (and zero-beat point) up or down a little
from time to time seems to help minimize ear (or is it brain?) fatigue.
If the filters are not set too narrow I find that the RIT does this for me.
