What is The Xtal Set Society?

The Xtal Set Society, founded in 1991, is dedicated to once again building and experimenting with radio electronics. Our newsletters are packed full of projects and information about Crystal Radios, mostly dealing with design and electronics issues. Each newsletter contains lead articles---and often, a building project and membership correspondence. Our lead articles are written by members of the Society. Occasionally we reprint a hard to find article from the 1920's or 30's. Members are encouraged to send projects and information to the Society and to correspond with each other.

Over the years we have listed vendors and sent our members elsewhere for parts. We came to realize that some of the national outlets for parts were no longer serving our needs, so we searched until we found manufacturers willing to create parts for the society. You’ll find those on our parts page.

Is there really that much to write about Crystal Sets? Yes! Here are some titles from our lead articles over the last few years: The Design of Unpowered AM Receivers The Simple TRF Set; Radio Outfit in a Headset The Den Two Crystal Set; A Crystal Set Revisited/Reconstructed From Crystal Set to Super Heterodyne; Marconi Type 107-A Tuner; Ten Best Crystal Circuits; Grounded Loopstick Tuner; An FM Xtal Set; Crystal Set Driven by a 400 ft Vertical; The Foxhole Set; Two Quaker Oats Radios; The "Cigar Box" Crystal Radio Set; Measuring Coil Capacitance; A Crystal Headphone from a Cat Food Can; Home-Brew Curve Tracer

We welcome your letters, and we enjoy reading the crystal radio stories sent in by radio enthusiasts. The members of the Xtal Set Society enjoy them too, so we include portions of many of our letters in the Membership Correspondence section of the Xtal Set Society Newsletter. We also publish interesting articles submitted by members of the Society, so if you have something that you think other crystal set builders would like to see, please send it in!
