Summary

Description
Svenska: Kristallmottagare, kristallen och avkännaren av märke "Ideal" D.R.P. (Deutsches Reichs Patent)
English: Cat's whisker detector, an antique radio component, from a Swedish crystal radio receiver. It consists of a fine wire attached to an adjustable arm that touches the surface of a crystal of galena (lead sulfide). It was used in crystal radios from about 1906 to World War 2. It functioned as a crude semiconductor diode, rectifying the AC radio signal to extract the audio (sound) signal from the radio frequency carrier wave.
