But you CAN build a crystal radio for the FM (VHF) range. I thought not also but I've seen it elsewhere. The antenna coil is a tiny thing in that case, for it to receive in the VHF range.
Anyone notice these crystal/foxhole radios actually sound better than a normal AM radio? I mean, I can actually HEAR high frequencies like the S in speech and things like that and there's no way something like this could receive FM.
@855h0le He could have the "plates" such that one is inside the bottom of the first cup, half diameter. Then the other plate of the capacitor goes half way around the bottom of the other cup. There would be the single inner plastic cup as a di-electric. Then as you turn the outer cup, the "plates" (whatever used, maybe aluminum strips?) would then variably overlap thus changing the capacitance.
This dude kicks ASS! Such a simple, yet useful manner. Thanks so much for this video!!

How did you make your variable capacitor? Did you use plans from a website? What is the URL?
