[Elecraft] K3 and phasing & noise cancelling systems

[Gary Smith]

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 give the 
NCC-1 a try. 

The price of a new one for an experiment that may well not work is 
more than I can afford. So if anyone has a NCC-1 they are not finding 
useful, please contact me directly, a good used one is at least worth 
trying out; if it works, it would be a Godsend.

It would be awesome if Elecraft encompassed this in a K3 update but 
I'm not holding my breath on this one. 

Thanks & 73,

Gary
