Building Your First Crystal Radio

A total waste of money. I found myself looking for the rest of the book, as there are no instructions for actually building a radio. Sample sentence: "More advanced radios have more parts and more complex schematic drawings". That's as detailed as this book gets.

Everything in this book can be found in the introductory pages of other books on the subject, other books that go on to provide far more useful information. You definitely could not build a crystal set given the information in this book.
