Thank to all for the replies!
After talking with the tech at DXE it appears the problems involved
in removing my QRM with something like the NCC-1 are iffy at best.
After numerous failed attempts at using different Rx antennas, my
best chance to reduce the noise to better levels appears to

Subject: [Elecraft] K3 and phasing noise cancelling systems
I've been having terrible RFI issues on the low bands, sometimes its
up to 10M but usually its from 40M down with 160M being the most
affected. I've become aware of the MFJ and DXEngineering phasing

I have a NCC-1, and it works well. My antennas are a vertical-firing
cubical quad for 75 meters (NVIS antenna) and a low 80-meter dipole
(noise sense antenna). I do not have a steerable array. Keep in mind
that the noise cancelling unit will null out noise from ONE direction
only. If you
A couple of years ago I proposed that Elecraft modify the firmware in
the K3 to allow the phase of the local oscillator in either the main
receiver or the subreceiver to be adjusted in some way (possibly by
using a couple of front panel buttons to be used as increment/decrement
controls).
