Newnes Short Wave Listening Handbook

In this handbook, the author has divided the information into two parts, the first covering the "science" side of the subject and the second covering the use of sets. The first section provides information ranging from a few simple electrical "first principles" through a brief treatment of radio transmission methods to simple receivers. The emphasis is on practical receiver designs and how to build and modify them, with several circuits in the book (from the crystal set to converts, regenerative receivers, direct conversion and simple superheterodyne sets). Various "peripherals", such as aerial tuners, filters, preselectors, noiselimiters and CW and RTTY terminal units are also covered. In the second section concerning the use of sets, the author discusses what can be heard, the various bands, propagation, identification of stations, sources of information, QSLing of stations and listening to amateurs. Some computer techniques, such as computer morse decoding and radio teletype decoding are also covered along with computerized record keeping and other applications of the computer in the shack. Interference sources and cures are also investigated.
