    So interesting, in fact fascinating. The crystal sets on your page are wonderful. I am in the process of building a crystal set now again (we did previously in boarding school - 60 years ago!) and will be coming back to your pages for hints and circuits often. There is something immensely satisfying in being able to receive radio signals with the minimum of basic components. I haven't tried a foxhole radio yet, but that's on my agenda.
