I am mostlly a CW operator, and find that the Orion II NR (v2.044A), with a
wide (6 kHz) roofing filter (tnx Bob, K8IA, for that tip) does help pull
out the weak ones on 160 and 80 meters. I don't have the "golden ears" of
some of you phone ops, but agree that on SSB, the NR does seem to attenuate
the high frequencies.
However, to me that appears to be a software issue, not something that
would justify trading in the rig for an Orion III. In addition, there seems
to be a consensus that a better spectrum display is something best done
externally. So, as the guy who started this thread about an Orion III wish
list, it looks like we're down to only two major items: better data I/O (to
feed the panadaptor, Skimmer, etc.) and a sub-receiver with the same features
as the main receiver.
The former can easily be done as a factory mod (or, for the brave, a user
mod), which leaves us with the sub-receiver as the main justification for an
Orion III at all. Is that enough? What do you think?

Hi all,
I agree. I'd go with an external panadapter. Why are people rumbling about
an Orion III? Let's get the O-II finalized first. I am still waiting for
an upgrade that will improve the NR part of the rig. One that, when you
activate it, will truly reduce the noise WITHOUT altering the audio
quality
of the voice you're receiving.
On some signals it seems to work okay but mostly it distorts the audio and
acts erratically and I am running ver. 2.044A. Different settings of the
AGC threshold and manual AGC level do not seem to make much difference.
