Horsepucky. If RF is getting into the K3, the radio has a design flaw. And it does -- improperly terminated shields, also known as "the pin 1 problem," which is a well known and well documented cause of RFI. The ONLY proper connection of a cable shield is ZERO LENGTH to the CHASSIS, and NOT through an RF choke! 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
