[Elecraft] K3 loss of rx signal

[Gmail - George]

Bill,
Try using a sharp soldering aid to "tighten" the female connector contact on 
the K3 & P3.
Pry the female center contacts inward just a bit.

Jim,

I too had an issue with a couple of cables between my K3 and P3. Had to
wiggle the cable every few days to get rid of the extra noise on the
P3.  Finally replaced the cable with a 3 foot Amphenol BNC cable, part
number 115101-30-36.00 and have never had the issue again.  The cable is
made with LMR-100, which is skinny and flexible.  It's currently in
stock at Mouser for $18.66.
