    Description

    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 and Perikon Detector Stands 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.
