Planning and Engineering of Shortwave Links
Description:
A concise account of planning and design of shortwave links in the 1.5 to 30 MHz frequency band with a view to their practical application. This edition incorporates the new frequency allocation plan published by the UIT in Geneva in 1982, plus the new designations for classes of emission, comparing these to the former designations. Discusses the phenomena along a radio path that cannot be influenced by technical means, and also includes the recommendations and reports of the CCIR for achieving freedom from interference and requirements for quality and reliability of transmission. Also provides information on the technical properties of transmitting and receiving antennas important when attaining specified parameters. To reduce calculations to a minimum, it provides diagrams and nomograms from the technical literature. Extensive references.
