A sample illustration from “Making a Transistor Radio”
Those of you who are ham radio operators (especially QRPers) are familiar with the name George Dobbs (G3RJV). In 1972, Reverend Dobbs wrote a book called, Making A Transistor Radio and now it’s available online.
Making A Transistor Radio is a clear, simple, step-by-step guide to building your own transistor radio. In each stage of the process you’re rewarded with a working radio. In addition, you’ll learn about all of the stages of a working receiver.
Perhaps what I love best about this book–besides the fact that is resembles the mountains of electronics books I poured through in my youth–are the illustrations. Each illustration describes exactly how each component of the radio should be built, leaving nothing to be pondered.
If you’ve ever wanted to build your own radio, from scratch, this is a great place to start.
