[Elecraft] The K4's new noise reduction

[Barry]

Olli,
     You are correct. He did give the answer. Mea culpa. Somehow, I 
missed that.

73,

>>>We've recently started testing a new DSP NR (noise reduction) algorithm for the K4. Our early testers are saying it's as good or better than anything else they've used, removing stochastic noise without the characteristic "hollow" sound of earlier algorithms. In my own tests, I'm finding weak SSB signals I simply couldn't copy without it. It goes beyond just reducing listening fatigue. This type of NR operates in the frequency domain, like spectral subtraction, but without the usual artifacts (musical tones) or long sampling delays.
