Description
Deutsch: Detektorkristalle mit Verkaufsverpackung aus Blech
English: Crystals for use in cat's whisker detectors in crystal radios, with manufacturer's shipping box. The cat's whisker detector was an antique radio component used in radio receivers in the early 1900s. It consisted of a fine wire touching the surface of a mineral crystal. It functioned as a crude diode to rectify the radio signal, extracting the modulation from the radio carrier wave. The text on the box lid says in part: "Highly sensitive detector crystal"
