I "fiddled" with HI CUT a lot at first, to determine how narrow I could go
and still maintain excellent intelligibility.  Once I settled on 1500 Hz, I
asked INRAD to make some 1500 Hz roofing filters (actually about 1600 Hz)
for contest work.  Like you, my SSB bandwidth (DSP: 1500 Hz, crystal filter:
1600 Hz) hasn't been touched for three years.
