    Experimental Semiconductor Crystal Radio Crystal Radio Diode Cast in Brass Cup
    Size, Color and shape may vary from pictures
    Chalcopyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula CuFeS2.
    Chalcopyrite has
    electrical characteristics suitable for use as a detector in Crystal Radios.
    The "Perikon" Crystal Radio detector for example used two minerals, A Fixed Cup Chalcopyrite and
    Zincite
    or Bornite in the movable section.
    Cast Bornite Crystals Coming Soon to my eBay Store.
    It is also possible that
    Chalcopyrite will also work in a standard cat whisker detector stand but may require some type of circuit biasing.
