Grant,
You peaked my interest. I attempted to find examples of spectral
subtraction and only found talks about it (no audio examples). Would you
happen to know where I might find some examples? Maybe comparing results
between several noise reduction methods?
Thanks!

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 … :)
