Hi Geoff!

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.

I don't think the knob (which I too would like to have) is practical 
given the K2's architecture.
