I have a spool of magnet wire and several round forms on which to wind coils. If I know the gauge of wire, and the diameter of the coil form, is there a way to calculate the number of turns required to receive the AM band? ….or any other bands?
My air-variable cap is from an old Hallicrafters and I believe it’s appx 500pf.
Thank you!
I think the on-line calculators are easier. https://www.crystalradio.net/professorcoyle/index.shtml
Lots of good crystal radio resources on this site.
