Hey Grnt,
I would be more than happy to send both radios to you!
I am not suggesting that either radio can create something from nothing.
What I am stating as "fact" is that both my other radios have the ability to
not inject raspy noise on top of original signal...which in turn allow me to
appreciate the better s/n ratio. The Orion can't deliver that due to the
noise it injects with the signal. There is a threshold somewhere where this
introduced distortion diminishes.
I have done several a/b/c with the same signal/antenna and find the NR on
the Orion II worthless for cw work with signals at or slightly above the
noise floor.

[p';/.q> The bottom line
As an afterthought, I'll be happy -- if someone would provide one or both
of
these two radios -- to replicate the tests I ran on the Orion I/II
regarding
Nr driven improvement in SNR vs. receive bandwidth. Alternatively, I'd be
happy to discuss the methods and systems used in some detail so that the
tests could be replicated by anyone else wanting to take it on.
The results from the first round gave the nod to the original Orion NR
code,
quite better than the Orion II revision. Neither were good at narrow
bandwidths (and I'd wager the 1000MP or TS-2000 suffer the same fate, not
because I have second sight, but because of the physics of noise). You
can
find the data back in the archive -- I lost a disk drive along the way,
and
no longer have the original posting in my mail archive.
Might be an interesting comparison, and would certainly wrap some facts
around what are otherwise anecdotal rants (in stereo) about who's is
better.
If you can find me an NR in-radio-function or external box -- amateur
radio
equipment, affordable, no DARPA or NIST projects worth big bucks -- that
actually works the miracles attributed to it at all times, in every case,
I'll buy it. Shucks, I'll buy TWO. Or at least nominate it for radio
saint-hood :-)
