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.

Download or read book Keep Watching the Skies written by W. Patrick McCray and published by Princeton University Press. This book was released on 2021-08-10 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the Soviets launched Sputnik in 1957, thousands of ordinary people across the globe seized the opportunity to participate in the start of the Space Age. Known as the "Moonwatchers," these largely forgotten citizen-scientists helped professional astronomers by providing critical and otherwise unavailable information about the first satellites. In Keep Watching the Skies!, Patrick McCray tells the story of this network of pioneers who, fueled by civic pride and exhilarated by space exploration, took part in the twentieth century's biggest scientific endeavor. Around the world, thousands of teenagers, homemakers, teachers, amateur astronomers, and other citizens joined Moonwatch teams. Despite their diverse backgrounds and nationalities, they shared a remarkable faith in the transformative power of science--a faith inspired by the Cold War culture in which they lived. Against the backdrop of the space race and technological advancement, ordinary people developed an unprecedented desire to contribute to scientific knowledge and to investigate their place in the cosmos. Using homemade telescopes and other gadgets, Moonwatchers witnessed firsthand the astonishing beginning of the Space Age. In the process, these amateur scientists organized themselves into a worldwide network of satellite spotters that still exists today. Drawing on previously unexamined letters, photos, scrapbooks, and interviews, Keep Watching the Skies! recreates a pivotal event from a perspective never before examined--that of ordinary people who leaped at a chance to take part in the excitement of space exploration.
