My catalog of Crystal Radio Hookups...

The following catalog features circuit diagrams hand-drawn by myself from various sources (as indicated on each page, see catalog reference). When I first entered the crystal radio hobby, I was amazed and more than a bit intimidated by the sheer variety of circuit possibilities. I began to make my own circuit drawings in order to get a handle on this in addition to finding interesting circuits to construct myself.

To organize the circuits from fairly easy to rather complicated, I put together a simple classification based on the number of Inductors and Tuning Capacitors in each circuit and a few of their main distinguishing features. Better classifications may exist, but this works well enough for my purpose. A legend follows so anyone may break the code.

I provide only minimal information about each circuit. Although an experienced builder may make the calculations to build a radio from the data provided, I mostly intend this for information only. I highly recommend if you wish build a set to consult the original reference.

I intend this document to be printed on double-side letter paper, folded over or cut in half and then bound. My paging system in the document only makes sense when this is done.
