[HCARC] Baluns and Unun's

[Gary and Arlene Johnson]

I kow about HRO, but I am trying to avoid the $30-90 per Balun if possible. 
Somewhere along the line I have to find something I can HOMEBREW in this 
hobby, and I figured baluns and ununs might be a place to start and 
instructions on how to make each and a source for the parts.

Maybe we need a training session before a meeting on building baluns and 
ununs.  That preceded by a session on basic soldering.
