I've just posted a new version of my tutorial on RFI, Ferrite Chokes, Baluns, and audio for hams. It has the same filename as the original, but the title shows Rev 1, 25 Jul 07.
The new stuff is primarily confined to pages 29-36, which addresses choke baluns wound with big coax (RG8X, RG8). There is a major update to the Choke Cookbook, based on extensive measurements of these chokes. There are also some additions to the appendices, and a few tweaks and typos fixed throughout the document. This is the first major update since 20 Jan 07. If you're winding any coax chokes, you NEED this update. Enjoy! 73, Jim Brown K9YC _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
