[Elecraft] K3S Noise reduction Test

[Robert Cunnings]

Well, not exactly... the K3S doesn't have the ability to perform the 
phase shifting for noise cancellation.

However, the K3 has antenna OUT and IN jacks which allow the use of the 
NCC-1 (now NCC-2) from DX Engineering to perform the noise cancellation. 
I've been doing this for years and it works well. I posted the details on 
this list earlier:

I need noise cancellation more and more as the RF environment in my 
neighborhood grows more hostile each year.
