[Elecraft] K4 -- Spectral subtraction noise reduction

[Grant Youngman]

I’ve recently been exploring quite a few of the many SDR receivers on KiwiSDR.  One of the (many) features of this system is an option to select spectral subtraction NR.

I’m now really hyped about the fact that this will be available at some point on the K4.  It works exceptionally well.  So well, that I leave it turned on most of the time.  Often, stations you can barely copy down in the junk literally pop up out of the noise.  Don’t know if this will be available at initial shipment, but it’s certainly something to look forward to if not.  I’ve only tried it on AM and SSB at this point, so not sure about CW.  

Just something else to whet the appetite for that eventual “you’re up” email from Elecraft sales …  :)
