We learn how to assemble structures of any complexity.” This book will help modernize and expand on some of the basic designs. You will learn how to read circuit diagrams, work with a soldering iron, and create many interesting homemade products. You will learn how to use a measuring instrument, design and create printed circuit boards, and learn the secrets of many professional radio amateurs. In general, you will gain enough knowledge to further master electronics on your own. The book also contains a small reference book on radio components, which may also be of interest to professionals. This textbook is written in accessible and simple language, without unnecessary literary lyrics. To introduce young radio amateurs to electricity and various measurement quantities, a basic comparison method was used. Next to each circuit diagram is an image with the appearance and pinout (location of pins) of radio components. Everything is described in detail, sometimes the installation of a particular device is presented so that you can visually see what should happen.
