I found this on the internet while doing some research on crystal radios. It is an FM crystal radio. The URL is http://solomonsmusic.net/FM_CrystalRadio.html. I think that it may be worth building, just for fun. Any thoughts?

You can always detect FM with a slope detector...that is, an AM detector tuned off-center. The linearity of this generally sucks, especially for wide band broadcast FM, but it works

I hope to build this soon as I can find the proper variable capacitor (may have to special order it). I will let everyone know.
