EXACTLY RIGHT. Twisted pair, in general, provides very good rejection of hum, buzz, and RFI, and CAT5/6 is VERY VERY GOOD twisted pair. Shielding doesn't hurt, but it doesn't help either. Twisting is enough. The important thing is to follow Joe's advice on wiring. 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
