Hmmm. Interesting. So when you say "scramble wound coil" do you mean just some random wire wound by hand without regard to turns or wire gauge?

Yup, that's exactly what I do. I forget how many turns I put on the T.P. tube, but I'd say about 75-100 of plain enameled copper wire.

You might want to check with the "experts" to see if you fancy that idea before doing it. I'm not known for following "rules" too closely .... your results may vary.

cheers

EDIT :: I have toyed with the idea of using a surplus variable IF transformer (and removing the capacitors) as a coupling device but I never got that far.
