How To Build Working Radio Receiver Components Entirely from Scratch. Softcover, 185 pages, 120 photos. "The Voice of the Crystal has a stellar reputation amongst radio geeks, and for good reason. This guide to building radios is filled with great ideas and utterly awesome projects." - Gareth Branwyn, Make Magazine". Fascinating stuff indeed! Highly recommended for the keen constructor - especially those wanting an interesting challenge!" - Rob Mannion, editor, Practical Wireless Magazine. "The Voice of the Crystal is essentially a guidebook to the art of building radio receivers from scratch. "Scratch" doesn't mean components purchased at Radio Shack, or lifted from abandoned gear. This is "scratch" in its most elemental sense -- discarded glass, scrap metal, you name it. (This book) takes the concept of elementary radio to an entirely new level." - Steve Ford, Managing Editor, QST Magazine". I confess when I first saw the book and read the subtitle, I surmised that this book might be too much of a "niche item," something only for subspecialists of a dying art. But this book is broadly educational in a way I never expected. Whether or not you plan to build your own crystal set, this book is a delightful read. Frankly, I couldn't put it down. I can't think of a better way for a fledgling scientist--young or not so young--to make a beginning at learning the secrets of nature." - Sheldon Greaves, The Citizen Scientist.
