But it all comes as the result of a lot of serious study, and of listening to others who have done the same. W1HIS was the guy who I first saw articulate the significance of using a serious common mode choke at the feedpoint, and he published a serious tutorial on the topic. The only thing he got wrong was that his winding instructions were wrong because he didn't know how to measure the chokes accurately, and he didn't quite understand the chokes at the time he wrote it. he also didn't know about the newer #31 material, which I knew about because of my previous research.
Likewise, much of what I've learned about RFI, including the importance of twisted pair in rejecting RFI, is the result of learning from other members of the EMC Working Group of the AES Standards Committee, of which I've been Vice-Chair for ten years, (especially Neil Muncy and Bill Whitlock), and from studying the work of Henry Ott. They're the smart guys! 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
