I would have thought the center pin would be smaller for higher Z connections (???).
Look at the size of the center conductor in a piece of RG-59/U. Although, as usual I may have that completely wrong. 73, Charlie k3ICH -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of [email protected] Sent: Monday, April 03, 2017 8:43 AM To: Guy Olinger K2AV <[email protected]>; LA7NO <[email protected]>; [email protected] Subject: Re: [Elecraft] K3 loss of rx signal I had a similar frustrating problem with a BNC patch lead. I bought some cheap leads at a rally and I didn’t notice that the plugs were 75 Ohms. The leads worked OK, but the centre pin was thicker than the 50 Ohm version and it splayed out the centre connector of the socket, so when I plugged a 50 Ohm patch cable back in, the centre pin did not make contact any more. It took me a long time to find the cause, and now all the 75 Ohm leads are in the bin. 73, Danny, G3XVR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
