You can clearly see how the hula hoop coil couples to the antenna and how the capacitor helps tunes the L-C circuit. Very clever demo.

KC8YOQ DE NG9D – THAT CAP IS AN OLD 365pF THE KIND USED LONG AGO IN AM BC RADIOS. YOU CAN ALSO USE VARICAPS, A LITTLE L-C EXPERIMENT! 73 DE NG9D . .

I looked in all my old bcb radios BUT no luck! Do you have one that you wish to get rid of?

Ha ha… I have been on that station! When I was a kid, we were in the ‘Scholar Bowl’ quiz show. I failed miserably in the topic of Earth Science–but got on the radio. We listened to countless hundreds of hours of WMT in the barn milking cows. I’m building your loop, sir. I have a similar SW receiver.
