Tried responding to the original query before but used the wrong
email address and 'fraid it got stuck somewhere for review.
Certainly agree that hardware NB works very well. Takes out power
line noise here handily. I have found one use for the DSP NB and
that is with the
Asian OTH radar. If cranked up to 9, it takes most of it out here in
the OR. As for the NR, opinions vary. When I've listened to SSB
it does sound as if it works fairly well. On CW, it distorts the
signal and reduces the background noise to gurgles. Actually, more
harm than good. Running v2.059d here as well.

I find the NR on the Orion V2.059 to work very well. It does an
effective job of acting like a sort of squelch for SSB and I like the
fact that there aren't alot of artifacts in the process. I didn't
like
the V1.372 NR function as it created a ton of artifacts reminiscent of
an outboard DSP device like the NIR-10 and the "Hear It" speaker
devices. Kind of an underwater sound...
The hardware noise blanker is also quite effective on pulse noises. I
have however found the DSP "side" of the NB to be totally ineffective.
I have never found a situation where it makes any difference or
improvement.
Hope this helps.
