Rick, this isn't my first brush with binaural "magic". I got the
latest and greatest DSP599ZX when it came out several years ago
because of the binaural hype and it just didn't do much for me then or
on the Orion now.
It is my understanding that "diversity" is what binaural tries to
simulate. I think that the binaural methods here have all been without
diversity of receiver or antenna. That may be significant.
I have used a Yaesu rig with dual receive (and I kept my OMNI VI with
the opportunity of even trade, btw) and stereo headphones, using
different antennas (diversity of antenna) and found my ability to
"hear" down into the noise really enhanced. Kept the OMNI VI for other
reasons (this was about 6 years ago, still with the OMNI).
I'd rather the dsp engineers refine their basic algorithms for
demodulating weak signals in noise rather than all the NR, binaural,
etc bells and whistles which I've never found a use for. I still
think the Orion could do a better job with the basics of weak signal
reception.
Good point. Two receivers with separate antennas fed into stereo
headphones appears to be a significant enhancement to me. I haven't
done the research, but it may be receive phase angle diversity that the
brain can work with. It may have to do with what separate antennas we
use. Anyone do much with this stuff?
