[Elecraft] K3S Noise reduction Test

[GRANT YOUNGMAN]

You might want to look at actual (S+N)/N data.  I’m not sure the visual “test”  tells the full story, since these are complex waveforms. 

I did extensive measurement several years ago on the NR functions of the v1 and v2 firmware versions of the TenTec Orion (for some reason, noise reduction not being “magic” surfaces everywhere as a contentious issue), and the measured data did not always match what things ”looked like”.   Not saying they don’t here, but it’s improvement in (S+N)/N that’s the end objective of NR regardless of what the screen shot looks like.

SpectrumLab can measure this directly.  http://www.qsl.net/dl4yhf/spectra1.html
