[TenTec] Tutorial on RFI, Ferrite Chokes, Baluns, and Audio for Hams

[Jim Brown K9YC]

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!
