[Elecraft] K3 loss of rx signal

[Bill Breeden]

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.

73,

Bill - NA5DX

Yes, those great folks at Elecraft sent me a replacement cable gratis, but I have to deal with this every time I'm on the radio. I've cleaned, tweaked and replaced, and the display problems come back eventually. I'm shopping for making my own, and want to use amphenol solder (clamp) style for RG-58. I've boiled it down to 31-2 and 31-212 (not 31-212RFX). On the technical drawings the pins are drawn as a different shape! I can't see any other difference except for price. I plan on also cabling to the RX ANT In. Several posts were made regarding this subject including a link to the general amphenol BNC page, without sharing which specific part you use. Could you please share the exact part you use and why? Thanks! Jim WN8A
