Download or read book The Early Shortwave Stations written by Jerome S. Berg and published by McFarland. This book was released on 2013-10-04 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The World of Ham Radio 1901 1950 written by Richard A. Bartlett and published by McFarland. This book was released on 2015-01-28 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the first fifty years of the twentieth century, ham radio went from being an experiment to virtually an art form. Because of the few government restrictions and the low monetary investment required, the concept of ham radio appealed to various people. More than just a simple hobby, however, ham radio required its operators to understand radio theory, be able to trace a schematic and know how to build a transmitter and receiver with whatever material they might have available. With the advent of World War II and the increased need for cutting-edge communications, the United States government drew upon the knowledge and skill of these amateur ham radio operators. This book explores the history of ham radio operators, emphasizing their social history and their many contributions to the technological development of worldwide communications. It traces the concept of relays, including the American Radio Relay League, from contacts as close as 25 miles apart to operators anywhere in the world. The book highlights the part played by ham radio in many of the headline events of the half century, especially exploration and aviation "firsts". The ways in which these primarily amateur operators assisted in times of disaster including such events as the sinking of the Titanic and the 1937 Ohio River flood, are also examined.
