About this book

Crystal Clear: Vintage American Crystal Sets, Crystal Detectors, and Crystals (002) by Sievers, Maurice L.. paperback edition. ISBN: 9781886606036.

This book revisits the era of the simple crystal radio set, when a "cats 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. Company histories are given for the Wireless Specialty Apparatus Company and RCA.
