Crystal radio construction
WebA miniature crystal radio with ferrite rod tuner, by Doug Edwards. The Crystal Radio Society (the Xtal Set Society) has books, plans, parts, even kits, and a journal. The society was started in 1991 as amateur interest rekindled in crystal radios -- for the third time. Also on online forum, history and projects. WebA crystal radio, or crystal set as it is sometimes called, is a radio that only uses the power of the radio waves picked up by the antenna to generate the sound heard in the head phones. The reason it is called a crystal set …
