[Elecraft] K3 and phasing & noise cancelling systems

[Jim Wiley]

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 have multiple noise sources with signals coming in from 
different directions, you may be disappointed.  It does a bang-up job on 
the neighbor's plasma-screen TV.
