K3 - 50 Hz Shift

[Roland Guidry-2]

Working the WPX contest this weekend, I tried using the Shift when the DSP
filter was as narrow as 50-100 Hz for some very weak contacts due to QRM. K3
performed beautifully on CW I might add, but I think the shift adjustment in
50 Hz increments is too large. I would often lose the station I was trying
to work.
 
I would have perferred something smaller even as low as 10 Hz. Is it just
me, or is this something that can be menu adjusted in the future. I think
this would only be needed in CW/Digital modes.

Hi Roland,

I suppose this functionality is in relation with what is called "DSP
control granularity" and what was mentioned by Wayne some time before
in reaction to 10Hz step in PITCH adjustament and PITCH min/max frq
requests.
So I suppose it is tied together and was declared that after some more
critical jobs there is some hope to generally change "DSP control
granularity" to 10Hz.

73!

Maybe the shift increment should change automatically, so it is always
significantly less than the bandwidth.

Yes, my experience also.  50 Hz steps are too much
at the narrower DSP filter settings.  10 Hz would be
good and BW less than 200 Hz.
