The Superheterodyne Book - Antique Radio Servicing

"The Superheterodyne Book – All About Superheterodynes – How They Work, How To Build and Service Them" by Clyde Fitch, 4th Edition, 1940, 68 pages, Radcraft Publications.

This book was prepared to present in simple and clear terms as possible the theory, design and construction of Superheterodyne receivers. The purpose is to give the reader a handy reference book and guide that will help him in his work, whether he is interested in servicing superheterodynes or plans to design and build them. In any event, a thorough knowledge of the subject will be found the shortest and most sure route to successful receiver performance.

The superheterodyne has always been considered the supreme type of radio receiver. It is more complex and versatile in its actions than other popular types of receivers, and for this reason, has always been found highly fascinating by those who have studied it. However, a highly technical knowledge of all the various components of the supergheterodyne is not absolutely necessary for the practical man; therefore, only sufficient data of this nature to meet practical requirements are given.

The main bulk of the book treats with modern receivers of conventional design (as of 1940). As many varieties as possible of these modern receivers are included so as to give the reader a breadth of vision and not hold him down to fixed rules.
