A shortwave radio, without use of satellites, will receive commercial free foreign government supported English language radio programs from thousands of miles away! Shortwave radios can be built at home in a time period of a few hours to a few weeks. This book contains over one hundred illustrations. Written for both the expert and the novice, it provides information for understanding how the radios work, for obtaining the necessary parts, and for constructing the radios. Shortwave radios were first developed in the 1930s and new designs can be built to resemble radios of that era.

The Technician's Radio Receiver Handbook is an invaluable tool for anyone involved in the technologies of wireless, cellular telephone, telecommunications, avionics, and other forms of electronic communication using radio waves. The market demand for and use of wireless and telecommunication technology has increased dramatically over the past decade, leaving many technicians and other communications professionals with the need for accurate information on how the newest equipment works and how to fix any problems that arise. Joe Carr, a notable author in the amateur radio and communications markets, explains both the new and old technologies, the science behind the scenes, as well as troubleshooting techniques not found in any other book. The book will also have a companion website including helpful calculation software, customizable spreadsheets, and much more. - Written for technicians and hands-on practitioners in clear, easy-to-read text with many detailed illustrations - Contains information on cutting-edge receiver equipment as well as the most popular types used today in a variety of markets - Destined to be a constant reference and superb training guide for anyone interested in communications technology
