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

4 KHz receive passband *already works* with the FM filter.  Simply set
FC (shift) = 2.0 - 2.2 and dial in the desired bandwidth.  The *only*
reason that one does not get the full bandwidth is that shift is less
that 1/2 the width. The actual bandwidth achieved with the K3 in shift - width mode is [FC (Shift) + BW/2]
