Ok does anyone have a link that walks you through selecting the parts,
winding the balun etc... I'd like to make one but just can't find a decent
reference.

Go to the following webpage and order item #1542 for $3.00. You'll
receive three T-43 ferrite toroidal cores measuring 1/2-inch in

When you have the toroids and wire, get back to the group here and we'll
tell you how to wind the balun and/or refer you to a webpage on how to
do it.


Thank you all, will visit a local electronics shop (true electronics shop
that has lots of goodies, not Radio Slack) and pick these or their equivs
up.
