[Elecraft] Is NR effective on ssb?

[O. Johns]

David,

This is exactly how I would describe all the audio A-B examples I've seen/heard posted on the web, including Hector's and the ones with the LINGUA audio processor posted by Juergen.

Maybe that is all we can ask.  Oftentimes, when I'm tired and the band is disappointing, the noise begins to sound TO ME like speech.  If a human can't tell the difference reliably, how can we expect a DSP to do so?

For me, in my very high noise environment, even with the RF gain backed off, the noise interacts with the NR to give a hollow ringing cavern effect with the voices at the very back of the cavern.  Unless the ssb signal is pretty strong in the first place, the NR does not improve my experience.

But I'd still like to learn how to do it.  If someone in a similar high-noise environment has found the magic settings, please post them for the rest of us to try.

73,
