An Adventure in Crystal Radio

This 12-minute video explores a crystal radio built around a germanium diode and the home-construction of a rock-crystal galena diode using a cat's whisker probe. A 'spark-gap transmitter' is also heard through the crystal receiver. The book mentioned in this video, 'Wireless Priest: Archibald Shaw and the Maritime Wireless Telegraph Company', can be purchased online. In Australia, the cheapest site (as of Feb. 2025) is 'The Nile' online bookstore.
