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.

To an outsider, the world of ham radio is one of basement transmitters, clunky microphones, Morse code, and crackly, possibly clandestine, worldwide communications, a world both mysterious and geeky. But the real story is a lot more interesting: indeed, there are more than two million operators worldwide, including people like Walter Cronkite and Priscilla Presley. Gandhi had a ham radio, as do Marlon Brando and Juan Carlos, king of Spain. Hello World takes us on a seventy-year odyssey through the world of ham radio. From 1927 until his death in 2001, operator Jerry Powell transmitted radio signals from his bedroom in Hackensack, New Jersey, touring the worlds most remote locations and communicating with people from Greenland to occupied Japan. Once he made contact with a fellow ham operator, he exchanged postcards known as QSLs cards with them. For seven decades, Powell collected hundreds of these cards, documenting his fascinating career in amateur radio and providing a dazzling graphic inventory of people and places far flung. This book is both an introduction to the fascinating world of ham and a visual feast for anyone interested in the universal language of graphic design.

In 1873 Scottish physicist James Clerk Maxwell first advanced the idea that there might be electromagnetic waves that were similar to light waves, a startling concept to the scientists of his day. About 13 years later, German physicist Heinrich Hertz demonstrated in his laboratory that electromagnetic radiation did indeed exist. But it was not until after Hertz's death that a young Italian named Guglielmo Marconi got the idea for a practical communications system based on Hertz's work. Marconi was surprised and disappointed that the Italian government was not interested in his newly discovered wireless communications system, and thus he took his equipment to England. From that point on, the wireless became identified with Britain. From these beginnings, wireless radio became the basis of a revolution that has resulted in the satellite communications of today. This history first looks at Marconi's invention and then explores its many applications, including marine radio, cellular telephones, police and military uses, television and radar. Radio collecting is also discussed, and brief biographies are provided for the major figures in the development and use of the wireless.

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.

Ham Radio is Alive and Well, is packed full of useful information for both new radio amateurs as well as members of the Quarter Century Club. Anyone interested in amateur radio who reads this book is guaranteed to learn something new. This read ranks right up there with so many of the ARRL (American Radio Relay League) books and publications. If you enjoyed reading 200 Meters & Down, or The World of Ham Radio, 1901-1950, you will be fascinated with this text. Gary writes as if he is having a conversation with you over a cup of coffee while he explains many lesser-understood topics in such a manner that anyone can understand them. He shares what he has learned in recent years, and explains how ham radio has evolved and lived on amidst smartphones, PCs, and the Internet. The hobby is not dying but instead thriving and actually GROWING! Gary talks about "traditional" ham radio; the stuff hams did and continue to do using HF radios, antenna tuners, wire and/or beam antennas, working DX, QSLing, and contesting. It is about what he remembers from the past, and what is currently happening in the field of ham radio today. You will find bits and pieces of history as well as a little humor blended among many of the various subjects. This transcript is a must read for any inactive radio amateur and the licensee who wants to learn a little bit more than he already knows about this magnificent hobby. As Tim Duffy, K3LR, COO of DX Engineering, wrote in his forward of the book, "Whether you are a long time Ham Radio enthusiast or just getting started, you will find this book hard to put down."

An in-depth look at a century of radio history—and its continuing relevance in a radically changed world. A century after Marconi’s experimental transmissions, this book examines the history of radio and traces its development from theories advanced by James Clerk Maxwell and Heinrich Hertz to the first practical demonstrations by Guglielmo Marconi. It looks back to the pioneering broadcasts of the BBC, examines the development of broadcast networks in North America and around the world, and spotlights radio’s role in the Second World War. The book also features the radio programs and radio personalities that made a considerable impact on listeners during the “Golden Era.” It examines how radio, faced by competition from television, adapted and survived. Indeed, radio has continued to thrive despite increased competition from mobile phones, computers, and other technological developments. Radio Broadcasting looks ahead and speculates on how radio will fare in a multi-platform future.

In the early twentieth century, the magic of radio was new, revolutionary, and poorly understood. A powerful symbol of modernity, radio was a site where individuals wrestled and came to terms with an often frightening wave of new mass technologies. Radio was the object of scientific investigation, but more importantly, it was the domain of tinkerers, “hackers,” citizen scientists, and hobbyists. This book shows how this wild and mysterious technology was appropriated by ordinary individuals in Germany in the first half of the twentieth century as a leisure activity. Clubs and hobby organizations became the locus of this process, providing many of the social structures within which individuals could come to grips with radio, apart from any media institution or government framework. In so doing, this book uncovers the vital but often overlooked social context in which technological revolutions unfold.
