What an alternative to enameled wire?

A crystal radio does not use batteries. It draws electric power from the radio signal.
In theory, a Tesla generator draws electric power from the sun by connecting a circuit between the ionosphere (magnetosphere) and the earth.
Remember, light is just the visible spectrum of electromagnetism.

@mdnghtrdrr i found some kits at xtalman d o t com
they even have one with a tube. i think im going to buy one there

@lai2ke4 is a thinner or thicker gauge more beneficial? does it matter?

Do you have a schematic of your radio?

@mdnghtrdrr No, since I don't do that based on a single schematic but do modifications all the time. Just search the net, there are hundreds of them.

is it possible to make one without enameled wire?

I've recently built same the kind of crystal radio as yours. I tried adding two different kinds of variable capasitors between the coil but both of them don't work. The radio channels keep changhing by itself. Could you please tell me what should I do?

If you look closely, there are actually two coils. One antenna and one trap. The two variable capacitors connected in parallel with these two coils.
