Crystal Sets—Build 'em for Fun

摘要

Oh, those dear little crystal sets! We built them as kids, we are still building them as adults, and they continue to stand as popular homebrew items among radio amateurs and electronic enthusiasts of all ages. What is so special about crystal sets? They are easy and fun to assemble and get working, they are original free-play radios, and they also make handy survival radios for emergency preparedness. Experimenting with different circuit configurations and detectors is another reason for the great interest in crystal sets.
