[Elecraft] [K3]- K3 in NAQP SSB

[Brett Howard]

Good tip!  Makes perfect sense but I've just not really done enough
filtering with a real radio to figure this one out.  I have found that
dialing in a bit of shift can tend to help but my radio (TS-450Sat) only has
the set of fixed rocks for filtering.

Not clear how the width was reduced in your operation, but it should be done
with the HI CUT control, not the WIDTH control.  Once you get down to about
1.5kHz width, then you need to increase LO CUT about 100-200Hz for further
width reduction before reducing HI CUT again.  Done this way, most signal
are very intelligible down to 1.5kHz or so.  But using the WIDTH control
gives reduced intelligibility even at 2.2kHz.
