[Elecraft] Noise Nuller

[David Gilbert]

I didn't say that either.  Not at all.  I said that the local solar 
panel noise THAT I HEAR hasn't yet migrated into any of the FT8 
frequencies for me.

By the way, I previously offered to test the noise you hear using my 
NoiseNuller application.  All you have to do is record the output of 
your K4 in stereo while in diversity mode, with the recording preferably 
being of a desired signal being affected by your noise. I don't care 
what frequency you choose ... only whatever is bothersome for you.  You 
could use almost any combination of your existing antennas for the test 
... or even make multiple recordings using different pairs of antennas.  
I'll run that recording(s) through my application while making a screen 
video capture of it, and then post it to YouTube for you to see whether 
it helps or not. Maybe it will ... maybe it won't.

So far you haven't bothered to take me up on my offer.  You just keep 
telling everyone how bad your noise is for you.
