Alexander Patterson, head of Project Z, a US government organization hidden from the world under a lonely stretch of Texas desert, discovers a secret is not safe—a dark and dirty secret. Only two people know that the Space Shuttle Challenger tragedy was no accident. But on a computer disk drive, long ago relegated to the dusty corner of a forgotten scrap heap, a dead man's tale lies buried in the bits and bytes. Roger Howard, a newly appointed UCLA professor, buys a pile of old drives for his class in data recovery. And as the students begin to recover data, one of them is murdered. But Patterson knows the secret is still not safe until all threats are removed. He just didn't realize removing Roger Howard, an ordinary college professor, would not be easy.
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.
