[Elecraft] Is NR effective on ssb?

[O. Johns]

Folks,

I wonder if anyone has an A-B comparison audio recording that shows a SSB signal that is UNINTELLIGIBLE with NR off become INTELLIGIBLE with NR on?   (Note NR, not NB which is a different animal altogether.)

Maybe it is my ultra-high-noise urban environment, but I have not found any combination of settings of NR, RF gain, AGC, etc., etc. that lets me copy a SSB signal that I can't already copy without NR.  And I use the good Yamaha headphones that have been discussed on the reflector.  My theory is that S8 noise flummoxes the NR algorithm so much that it actually becomes a hindrance.  Maybe it can't really distinguish high noise from voice.

This is not to criticize Lyle or the K3.  I imagine that these algorithms have their limits no matter what radio they are run on.
