Crystal Radios & Parts

Crystal Radios & Parts

The most amazing thing about Crystal Radios is that they require no power to operate.
They get their power from the radio broadcast itself - which is one reason why they generally require a longer antenna than modern radios. Crystal Radios are 'old time' radios that receive AM radio broadcasts and are typically built with a minimum of components. They remain absolutely fascinating at any age. We manufacture what we call the Ultimate Crystal Radio Kit. It is an outstanding Crystal Radio Kit when assembled, and comes complete with everything right down to the sandpaper, brush and wood stain. The kit is available in an easy-to-assemble version, a more complicated 'craftsman' kit for experienced builders, or even fully assembled. Also available is our Antenna Kit as well as components for those who wish to build their own Crystal Radio from scratch.

Germanium Diode

Germanium Diode

Crystal Diode The heart of any crystal radio is the Germanium Diode. Modern silicon diodes require too much power to operate, so they are useless in the extremely low power circuitry of a crystal radio. Germanium Diodes are not as available as...
