This is an unique collection of useful and intriguing data for the traditional and modern radio amateur and the high-tech listener. Familiar radio topics are covered more concisely than in any similar book (for example, abbreviations and codes, symbols, formulae and frequencies) but the most interesting sections of the book deal with the newer features of the ham world - AMTOR, packet radio, slow scan TV, computer decoding, airband and maritime glossaries and so on. Based on the best selling Radio Amateur and Listener's Pocket Book, this Handbook has been completely rewritten and expanded to include new chapters on broadcast listening, instruments and interference. As a single source for a wealth of information and data, the Data Handbook is the most comprehensive and useful volume available, and will find a place in even the most crowded shack.
