Re: Tarnished Silver as a Crystal Radio Detector
I suppose that the main requirement of the detector material is that it can be made non-linear in some way. Hence many combinations of metals and general junk with corrosion/tarnish may work to a degree. As I have mentioned before on the forum when discussing crystal sets, I live not far from a long defunct lead and mineral mining area, and with a bit of patience and good eyesight you could still find galena crystals on the overgrown spoil heaps.
