Radio and Electronics Cookbook is a unique collection of electronics projects, ideal for all electronics enthusiasts and experimenters. The simple step-by-step instructions also make this book ideal for amateurs seeking to build up their electronics skills and knowledge.

The projects draw on the massive enthusiasm and design know-how of the RSGB, the UK's leading federation of radio amateurs. Only a basic acquaintance with electronics construction is assumed, with clear step-by-step instructions and numerous illustrations supplied throughout. The projects are also supported with features on the electronics involved.

The circuits themselves provide a wealth of quick, rewarding construction projects ranging from radio receivers and amplifiers to test equipment, a moisture meter, a desk microphone, a water level alarm, and Christmas tree LEDs.

  • A wealth of DIY and hobby projects
  • Written by experts who really understand home electronics construction
  • Includes factsheets to help you learn electronics basics as you work through the book
