My two centalvo's...
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.
73,
