Downward-expansion only for SSB, and DE plus bandpass filtering for CW. I
have found that in SSB, anything that cuts into the high-end of the bandpass
reduces the ability to copy.
In my experience, NR seems to work for CW, but I have never heard an NR
scheme on any radio that helped me copy an SSB signal that I couldn't copy
without NR. I have a feeling that anything that would work better on SSB
would require massive processing power that is not now available or
affordable, and/or introduce unacceptable latency issues.

Let me pose a question to you guys:
Regarding the NR function in the Orion
What approach would be best suited if TenTec allowed you to choose your
poison?

Grant,
Actually I've now gotten several off-line requests for just such a
reference. I used to have several books and magazines that talked about
it.
I've told everyone that I will go and search through the "stuff" I've got
in
the house and see if I can find any of those documents. I used to have a
lot of these references.
