As radio developed in the early 1920s, the focus for most people was the AM band and stations such as KDKA, the first broadcast station. There was, however, another broadcast method that was popular among many early enthusiasts?shortwave radio. As is true today, the transmission of news and entertainment programs over shortwave frequencies permitted reception over great distances. This book fully covers shortwave broadcasting from its beginning through World War II. A technical history examining the medium's development and use tells the story of a listener community that spanned the globe. Included are overviews of the primary shortwave stations operating worldwide in the 1930s, along with clubs and competitions, publications and prizes. A rich collection of illustrations includes many QSLs, the cards that stations sent to acknowledge receipt of their transmissions and that are much prized by long-distance collectors.
