This book revisits the era of simple crystal radio sets, when a "cat's whisker", piece of galena and a coil of wire were all that was needed to tune in a radio signal. It contains hundreds of photos and magazine ads identifying thousands of crystal radios and detectors made in the U.S. from 1920 to 1950. Presents company histories of four of the most influential manufacturers - Wireless Specialty Apparatus Company, Radio Corporation of America, Philmore Manufacturing and Western Manufacturing Company.
