Fm crystal radio schematics
WebTraditionally, in a crystal detector radio tuned circuits, a mechanical type variable capacitor is used. For those of you who would like to eliminate this mechanical component, here is a modern version of the classic detector set. This radio, as shown on Figure 1, uses a varactor diode instead of the usual mechanical rotary device. WebMy copy of the Heathkit Crystal Radio of the 50's. This crystal radio is a homemade copy of the Heathkit CR-1 Crystal Radio from the 1950's. It is built in a 6 x 3 x 2 inch deep plastic box, the same size as the original. It uses a double tuned circuit with two ferrite core coils and 100 strand Litz wire.
