Heathkit may be out of business but you can still get old and old-style crystal radio kits from www.xtalman.com. I put this one together with my six-year-old: Can you tell? Crystal radios use germanium diodes because they have a lower voltage drop than silicon, and are therefore more sensitive to weak radio signals.
