The NCC-1 is an excellent unit; the NCC-2 adds a TX antenna input port. 
It is most useful on 160 and 80, and still useful on 20. In all cases, 
success depends on your noise sources and the antennas you can phase. 
But it still boils down to the fact that you can usually only cancel one 
direction at a time.

I'm on 8 acres, so I have six RX antennas -- two reversible Beverages 
and a pair of VE3DO loops. I bought a very nice 8x2 RX antenna switch 
from K9AY, and feed the two outputs to the NCC-1. I also feed the K3 RX 
out to it, so that I can phase any of those antennas with the current TX 
antenna.
