Hi Helmut,
Could you pls process the analog parts of Mark's sample using the HPSDRs
noise reduction algorithms and post the results here for comparison?
Another gentleman tried the NR2 algorithm last year:

However the NR2 algorithm at that time was not effective at such low SNRs.
Thanks,
David

Thanks Mark! This result would be impressive, if reproducable. We refer
to our tests with 700C together with innovative HPSDRs using high
efficient noise reduction algorithms. As you see, we trust in digital
solutions, where we can detect possible improvement.

A comparison between 700D and SSB, recorded over a 40m path, with
approximately the same TX power (100W PEP).

I've spliced in the decoded 700D audio into the analog recording where
the 700D transmission started...
