Mike,
The spacing is about 15 mm like the article I followed to build it
suggested.
I think I have it working now. Don't think the card was connected!
duh.
But that wire down the center just doesn't seem like it would matter
after
all that center casing is part of the wire if in fact you do solder
one in!

Pete
