The homemade crystal radio is a type common during the 1920s called a "loose coupler" Text on museum label cards: Homemade Crystal Set Radio Receiver with 1920's Brandes Earphones Gift of L. A. Dolson. Radio, the transmission of voice without wires, was an amazing concept in 1920! A crystal set like this one didn't even need an outside power source, but could be listened to only with earphones because the signal received was very faint. Creating ones own crystal set was a popular pastime for science-oriented boys. Eastman Kodak Camera, 1925 T. T. Wentworth, Jr. collection
