Thanks guys! as soon as I hit the post button I thought oh boy,,,here it comes!!!!!!! what I'm doing is making a couple of crystal radios!!! I have a walnut size hunk of pyrite and it picks up good,,, this is just a forty year old hobby of mine,,,I finally got a razor blade radio to work after many, many tries. I know Nada about rock hunting and was thinking if you guys found it when looking for knapping stuff I may hit you up on that 'JW' thanks JEFFW
