Book Description
A shortwave radio, without use of satellites, will receive commercial free foreign government supported English language radio programs from thousands of miles away! Shortwave radios can be built at home in a time period of a few hours to a few weeks. This book contains over one hundred illustrations. Written for both the expert and the novice, it provides information for understanding how the radios work, for obtaining the necessary parts, and for constructing the radios. Shortwave radios were first developed in the 1930s and new designs can be built to resemble radios of that era.

Book Description
In July 1923, less than three years after Westinghouse station KDKA signed on, company engineer Frank Conrad began regular simulcasting of its programs on a frequency in the newly-discovered shortwave range. It was an important event in a technological revolution that would make dependable worldwide radio communication possible for the first time. In subsequent years, countless stations in practically all countries followed suit, taking to shortwave to extend reception domestically or reach audiences thousands of miles away. Shortwave broadcasting would also have an important role in World War II and in the Cold War. In this, his fourth book on shortwave broadcast history, the author revisits the period of his earlier work, On the Short Waves, 1923-1945, and focuses on the stations that were on the air in those early days. The year-by-year account chronicles the birth and operation of the large international broadcasters, as well as the numerous smaller stations that were a great attraction to the DXers, or long-distance radio enthusiasts, of the time. With more than 100 illustrations and extensive notes, bibliography and index, the book is also a valuable starting point for further study and research.

Book Description
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. For many in America and beyond, shortwave was an exciting aspect of the new medium. Some still tune the shortwave bands to enjoy the programming. Others pursue broadcasts for the thrill of the hunt. 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.
