I have Inv L connected to RX1 of my K3 and Hi-Z triangle connected to Aux RX
but no canceling system. I have to do this canceling in my head and it works
to the extend. I think, if you connect Hi-Z to one of the inputs of noise
canceling device and some noise antenna (TX antenna for example) to another
input, you will be able to do what you want. But then, switching the
direction of HI-Z will require readjustment of canceling device every time
you do that.

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 &
noise cancelling systems and how well they work to null out
interference. I'm leaning toward the DXEngineering NCC-1 although the
price is very high and that is holding me back from buying one right
now.
I have Amtrak 100' from my Inv-L transmit and HI-Z Triangular
antennas and Amtrak's 25KV arcing is killing me on the low bands. I'm
wondering if anyone here has a steerable antenna system similar to
the HI-Z that they use for Rx with their sub receiver and... one of
the MFJ or DXE phasing/noise cancelling systems.
If so, how do you have your K3 set up to handle the different systems
and how do you connect your noise cancelling unit so as to still
steer your Rx antenna?
Thanks
