Anyone got a circuit diagram?

$137.50... Dang.. Maybe I should start selling loops.. They sure
seem to be proud of them when they apply the price tag.
This is my version of the same appx thing, except using a
simple PVC frame. Can be built for chump change if you have
an old BC variable laying around. *If not , the caps can be
bought on the web.. I scrounge mine out of old analog stereo
receivers, radios, etc..

Yeah, I was thinking how fast I could mass produce say a dozen at a
time.
