Thanks to all who replied.


I would ultimately prefer to see the firmware modified slightly to further
narrow the bandwidth instead of a post-AF stage filter.

It seems, using MixW to analyze the output viewing the waterfall, that at
300Hz the bandwidth is actually closer to 600Hz wide, 300Hz wide either
side of center frequency.  I was hoping the 300Hz filter would be 300Hz
edge-to-edge, not 300Hz either side of the VFO frequency.
