Why would you think that? Properly designed, an air core balun and a ferrite core balun are electrically identical.
I did not mean to imply there's an inherent "defect" in ferrite cores, but they have limitations that air core inductors do not that must be considered in any design using them. We accept those limitations because toroidal cores also have major advantages over air core inductors, such as smaller size and inherent magnetic self-shielding. 73, Ron AC7AC -----Original Message----- They also didn't do much except make us feel better. Ferrite core chokes actually DO something useful. The cracked balun was poorly designed, so it overheated. That's a DESIGN mistake, not a "defect" of ferrite cores. 73, Jim K9YC ______________________________________________________________ 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
