For the first time, an amateur radio book with a video course appeared on the Russian market. The developments of the author of the book and his articles are widely known to readers of the most popular magazines for radio amateurs. And he wrote this practical book for those who have embarked on a difficult and interesting path from “teapot” to “pro” - after all, moving on this path is very difficult! In an easy and accessible form, the book explains the structure and operating principles of seven different designs. The devices are placed in order of increasing complexity, and are mastered step by step. The highlight of the book is that the designs of each Step were created by the author in several versions on different element bases - either on transistors, or on microcircuits, or on microcontrollers - so that you can clearly see and similarities and differences between circuit solutions. Where some circuit design options are not feasible (for example, an amplifier on a microcontroller), they are naturally not in the book. Real designs in a retro version are also interesting: on lamps, relays, thyratrons - this is how they were in the times of our fathers and grandfathers. The author developed, manufactured, tested and put to work all the designs considered - this is confirmed by the numerous videos contained on the disk attached to the book . The book will be of interest to all readers who want to expand their knowledge and practical skills in radio electronics. The book is accompanied by a disk on which a video course is recorded, videos demonstrating working structures, and there is a layout of printed circuit boards of all designs in electronic form. For all designs on microcontrollers, programs with source codes are provided on the disk. The disc contains a large amount of reference information for radio amateurs.
