[Elecraft] KX3 settings for 80SSB nighttime

[kg9hfrank at gmail.com]

Folks I have had a KX3 for years and used it mostly on CW (ok.. 95%).
With my rotator cuff surgery, I am up most of the night and listen on 75SSB.

I see NR, and of course PBT I/II as well as the RX EQ.  It dawned on me that I have never adjusted any of them.
Of note is PBT I/II where I am not getting full advantage of the optional filter.

The background noise at my QTH seems to be mostly atmospheric and S-5.  Any preliminary set-up that I can follow?
