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.

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 tuned antenna, high Q coils and HI-Z diodes, and more sensitive and matched headphones. See our technical articles pages for more details.

It's spring! Time to get outside and hang some antennas!

Have you ever tried a Beverage Antenna?

Crystal Sets? Yup, you’ve found an entire site about building Crystal Sets. 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, numerous books, and has parts and kits for purchase. A listing of newsletter articles from 1993 through 2007 can be found on the Technical Articles Page. Click on the earphones at left to browse and enjoy our site. You'll notice we've added parts, kits, and articles on ultrasound too, starting in 2009. --Patricia, The Crystal Queen Mum, Editor, Xtal Society News. Site last updated 05/10/2015.

The May Newsletter was mailed May 1. Dan, W7OIL, has written an article, on the front page, titled "Musings From a Long Winter." He describes hiding antennas from neighbors just in case. Stan Kaplan and Bill Howe have reported on their "A Really Big Crystal Radio." Bill Michna describes his Cigar Box radio; it looks neat. Carl Wick also presents his Cigar Box radio. Several pages of correspondence follow.

Results of the Cigar Box Crystal Radio Challenge were detailed in the March issue. Winners were Bill Holly, Larry Jeffers, Chip Olheiser and Anthony Dunn. An article titled Using a Transistor to Boost Crystal Set Gain was presented by Phil, WØXI.

The January 2015 Newsletter was mailed 12/30/14. To subscribe or download a sample, see the Membership & Newsletter page.

On recent trip to Oklahoma we discovered a bunch of old radio parts stored in the back of a now defunct radio shop of circa ~ 1950. See the lineup of items "sold as is" on our Specials page; just click the link in the left-hand column. Here's a picture of one of the items:
