[Elecraft] K3 Standard internal Noise

[donovanf at starpower.net]

I own several P3s and all were supplied with cables that are very 
susceptible to external RFI because of their very poor quality BNC 
connectors. I replaced the cables and my P3s have never had an RFI 
problem again. The Elecraft supplied cables went in the trash bin.

The coax cable supplied with the P3 at some period in time was known to be faulty.
