[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
