Still time to get those new antennas up before the first frost!
Crystal Sets? Yup, youve 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 07/17/2014.
