Standards? What standards? I quit having trouble when I started making my own cords with the 10 mm pins. I use the kind with a wrap around solder connection to the shield inside the cover. I also use teflon jacketed shielded coax of one size or another. Very permanent. Very shielded. Never melts when soldering. Bad cords and connectors are responsible for so much trouble 73, Guy K2AV __ 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 Message delivered to arch...@mail-archive.com

There also is an issue that caused me a lot of grief until I figured it out: some pins on RCA plugs are not long enough to contact the tongues on some RCA jacks. This could be an issue with the shoulders of the jacks or the shape of the shell of the plug. But the result is that the pin just barely, barely makes contact with the tongue, which is a recipe for all kinds of undesired behavior. I bought a little bag of simple RCA plugs with a longer pin and I now make all my RCA pinned cords myself. All the ready-made off the shelf cords have short pins. 73, Guy K2AV On Friday, September 16, 2016, wrote: > To those who replied to my plea... > Many thanks for your input. > Delving further into the rig it seems that when you put an RCA plug into > the socket it bends the centre tab down to complete a circuit and gives the > 12vhaving checked the volts etc there is 12v (fuse is fine) at the base > of the RCA but putting a plug in doesn't fully complete the circuit hence > no volts going out.
