Crystal Radios

Ben Tongue of Blonder-Tongue Laboratories has written extensively on crystal radios and crystal detectors. You can find the articles here. Ben is deceased. I have collected the articles and turned them into pdfs along with some other crystal radio stuff. As soon as I up load them I will post a link to the package.

The zipped package of Crystal Radio pdfs can be downloaded here.

What got me started on this was Diode Detectors for RF Measurement. And what got me into that was the design of an SWR Meter. I will publish that design when the board layout is complete.

Engineering is the art of making what you want from what you can get at a profit.
