Шпионские штучки, или Секреты

In this book discusses the features of circuit solutions used to create the miniature transistor radio devices. The respective chapters provide information about the principles of operation and characteristics of individual components and stages, concepts, and other information necessary for self-construction of simple radio transmitters and radio microphones. A separate chapter is devoted to the practical transistor designs microtransmitter systems short-range communication. The book is intended for novice amateur radio operators who are interested in the peculiarities of circuit solutions nodes and cascades of miniature transistor radio devices.
