Hey Steve,
Thanks much for posting this!
Is your driving loop approximately 10% the diameter of the full size?
If I remember, that's how I did my loops.
Totally awesome to have a vacuum cap!!
Makes the whole design so much nicer.
I picked up a surplus motorized potentiometer to drive my cap and
controlled it with a PIC.
works real nice.
I've been keeping my eye out on ebay for a broken MJF mag-loop.
I'd like to rob the control box and cap assembly out of it.
I like the way they DC control through the coax with inductors.
I know I could build that myself...but all the stuff is already their in
their box :)
Lazy mans home brew!
tnx,
Duane
