Condición: Very Good. xi,462p. illus. 24cm. ; OCLC: 786699 ; LC: TK6561; Dewey: 621.384131 ; This book is of "particular interest to transmitter design engineers and which will be useful to those engaged in transmitter operation and maintenance. Certain portions should also be of interest to the advanced amateur. It is assumed that the reader has at least attained the necessary knowledge required to obtain a commercial operator's license. Therefore no attempt has been made to go into the elementary principles of electricity. Conversely, the book does not give mathematical derivations of the equations presented throughout the text. The analysis of transmitter operation has been developed by first grouping and discussing circuits and components common to all transmitting equipment. Chapter 12 is devoted to the discussion of the particular characteristics of transmitters in specific services. Measurement techniques particularly applicable to transmitters are described in Chap. 13, and finally a brief summary of hazards associated with transmitters is given in Chap. 14. ; Contents: Frequency-control Techniques -- R-F Power Amplifiers -- Power Tubes -- Coupling Circuits -- Amplitude Modulation -- Angle and pulse modulation -- Power supplies -- Control and protective circuits -- Cooling -- R-F components -- Transmitter characteristics -- Transmitter measurement techniques -- Hazards associated with transmitters. ; red cloth with silver lettering ; no dustjacket ; ex-lib, stamps, label, date due, pocket ; else VG.
