The discovery and development of shortwave technology during the 1920s and 1930s permitted radio stations worldwide to transmit their programs over long distances for the first time, and the
thrill of hearing faraway broadcasts produced a dedicated American audience. Developments in shortwave radio from its inception through the war years were covered in the author's On the Short
Waves, 1923-1945: Broadcast Listening in the Pioneer Days of Radio (McFarland, 1999; paperback 2007). This book picks up the story in 1945, with the postwar resumption of organized shortwave
listening. The companion volume, Broadcasting on the Short Waves, 1945 to Today (McFarland, 2008), focuses on the world's shortwave stations. All three volumes are richly illustrated and
indexed, and feature extensive notes.
