On a fixed-tuned display, the P3 and P3SVGA waterfalls were displaying drifting bars of noise that moved with the VFOs, but could not actually be heard on either receiver of the K3 - in other words, they were internally generated spurious signals. When I replaced the supplied BNC cable with a disreputable-looking patch cable from the junk box, the problem disappeared.
On cutting away the plastic covers from the BNC crimp connectors, the metal sleeve on both connectors was found to be incorrectly crimped. The tool had been applied too far away from the connector body so that the crimp was squeezing mostly the soft cable, but failing to provide a solid 360deg clamping pressure onto the braid. > >My K3/P3 experience has been first-rate, but I suggest Elecraft should >take a look at their BNC cable supplier and consider upgrading for >future shipments. > Agreed. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
