If you want to read about another person´s obsession this is the book for you. It recounts how I and a band of friends in Sweden and abroad listened to signals from satellites from the secretive Soviet Union and other nations throughout the Cold War years and beyond. You will read bout how we kept a watch on cosmonauts and secret satellites using simple equipment always on "the trailing edge of technology". Richard Flagg, Robert Christy and Mark Severance have contributed chapters that provide their perspective on our common obsession. We were all part of the Kettering Group of satellite trackers led by the legendary Geoff Perry.
