NEVER connect a cable shield to "signal ground" -- this MAKES a Pin One Problem. The only proper connection of a cable shield is the SHIELDING ENCLOSURE (like the chasssis). When you disconnect the shield at one end, you stop shield current. That CAN be an acceptable fix, but it can also CAUSE noise and RF problems because it shields noise from only one end of the cable. 73, Jim K9YC ______________________________________________________________ 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
