Has anyone ever heard of anything like the experiment I am currently
concocting? I have taken an Amidon T50-2 toroid form and wrapped it with 57
turns of #32 enamaled wire, giving it an inductance of 16 uH, then wrapped
over that layer with 150 turns of #36 wire. The first layer (16 uH) I am
using for tuning my home-built active antenna, and am relying on resonance
to send a signal through the outer layer, which I *think* should act like a
step-up transformer for that signal. This layer is grounded on one end, and
feeds into the first stage of amplification on the other. And it does seem
to work, only the toroid seems to resonate at around 10 MHz with my tuning
capacitor set to 114 pF, when it should (I thought) resonate at something
lower, like around 3.7 MHz.

And like I said, the step-up transformer part does seem to work, but I can't
tune as low as I would like. Has anyone ever hear of anyone else trying
anything like this? If so, what is it called, and where can I find info on
the subject?

Many thanks for any help...
