AND each generic type -- ferrites and powdered iron -- have many variations that are VERY different from each other. The ferrite types are different as a result of their chemical MIX, and every MIX is designed for a different use -- that is, suppression over one range of frequencies and/or inductance in a different range of frequencies. See the RFI tutorial on my website about these matters. 73, Jim Brown 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
