DXing - listening to far off stations - has long been a part of the crystal set experience. Dxers strive to pull out those weak signals generally not audible with a beginner set. Optimizing a set for DXing requires a better antenna, higher impedance (hi-Q) coils and diodes, and more sensitive and matched headphones. See our technical artiles pages for a flavor of this aspect of the hobby.

Nearly 5,000 US radio stations occupy the AM and Extended AM bands: 530-1600 & 1600-1700. View our The Broadcast Band article for details.

The Society has been growing since 1991; still, some people are flabbergasted to find an entire society dedicated to Crystal Set radios or "Xtal Sets". One web surfer e-mailed, "I was so excited to find your site that I fell off my chair! "The Xtal Set Society publishes a newsletter and numerous books, all of which you can find more information about on this site. A listing of newsletter articles from 1993 through 2007 can be found on the Technical Articles Page.
