[Richard Fjeld]

Have you tried Rx equalization to reduce the hiss?

  I'm in the early stages of trying this out but thought I'd share in interest of helping someone else. 

  I've been using AGC threshold 10. 
  Im always fiddling with attenuator and rf gain. 

  I was listening to some activity on 20 & 40 and began playing with agc settings. 
  I ended up at a threshold that is totally not what I suspected to like. 2. You've got to be kidding,right,2?

  The downside is this can really decrease volume available especially with NR. I've just been using this a night and morning but one thing is apparent, I'm not constantly fiddling with attenuator and rf gain anymore. 
  Threshold 2 slope 5-10. 
  Noise level s5 on 20m. 

  I also picked up a GAP/BHI speaker and like the NR. It doesn't reduce volume as much. The best K3 match I found is NR F8-2 or 3. I really don't wish to use NR. 

  The hiss I've been complaining about with hi cut above 2.4 or 2.5 is drastically reduced also. I don't like 3.0 but 2.8 is pretty good. 

  I've got to spend more time in the saddle with these settings but I'm putting this out there for anyone else having pains with noise/rf gain.

  Once again bottom line: I'm not constantly fiddling with attenuator and rf gain with threshold 2.
