Much of this project was based on a "Mystery Crystal Radio" from the 1930s and the ARRL Handbook of 1977 . This is all highly experimental and I can promise the outcome will vary, but it will work. One final note on this coil is the two output connections (a, b) can be reversed for better volume.

Many of the projects described on these pages operate at voltages which are high enough to injure or kill. Do not attempt to build or operate any of these projects …

  • The main part of this book deals with understanding the required concepts to build a good basic crystal radio. Advanced concepts (to be written and posted last) will deal with a number of improvements that can be made to the basic design.
  • Much of this project was based on a "Mystery Crystal Radio" from the 1930s and the ARRL Handbook of 1977 .

  • I have heard, even from a physicist, that it is impossible to build FM crystal radios. On the other hand some experimenters claim that they have built them. This argument intrigued me to try and build an FM crystal radio, which I have done successfully. To my surprise, the result is an astounding performer, pulling in four local stations in Tucson.
