Hi friends.

Recently I added a new section to my crystal radios section, showing only my schematic drawings for the crystal sets that I built. The response was very positive as most people look at the schematic first when they are looking for a project to build.

This is understandable as you can quickly gauge the difficulty of a project by a quick look at the schematic.

Instead of going through scores of my pages looking for the project that is right for you, I have assembled the schematics all on 2 pages! So let's get started.

Enjoy. Dave Schmarder – N2DS
