While working in this part of the firmware, could 4K receive
passband be made to work with the 13KHz FM filter as well?
Thanks, Bill AE6JV

The K3's SSB receive passband can be widened to as much as 4.0
kHz if you have a 6.0 kHz crystal filter. This is useful for
ESSB in particular. However, there's a minor problem with the
present firmware that requires a workaround (for now).
The trick is that you have to have LO/HI CUT selected rather
than SHIFT/WIDTH. If you select LO/HI CUT, then NORMalize the
passband, you can adjust HI CUT to as high as 4.00, and the
DSP's bandwidth will be set up accordingly.
If you have WIDTH/SHIFT selected, you may only be able to get
the DSP's bandwidth up to 3.50 kHz, even though the display
says 4.00.
