Fm crystal radio schematics
http://rexresearch.com/xtlradio/xtlradio.htm WebJim. Jim's Crystal Radio Page. This is the schematic diagram of a basic crystal set. The tuned circuits in a crystal radio are composed of a coil (inductor) and a capacitor, usually variable, to allow tuning the circuit to the desired frequency. A crystal set can be made with a single tuned circuit (the detector coil), or with an added tuned ...
