That's where most people agree that SSB sounds best at that narrow bandwidth. In practice, the best way to get to that BW and FC is by normalizing, then putting the DSP controls into SHIFT/WIDTH mode and adjusting only HI CUT. Use only as much HI CUT as the QRM conditions require. Thanks to W0YK for that valuable tip. I use the 1.8 on SSB, but I told the K3 that it was a 2.1, so it cuts in when the DSP BW is reduced to 2.1 (by using HI CUT). The 1.8 filter sounds great at DSP BW=2.1. DSP BW can be reduced as far as 1.5 if necessary, and SSB remains intelligible.
