![]() The crystal radio receiver (also known as a crystal set) is a very simple kind of radio receiver. It gets its name from its most important component, known as a crystal detector, originally made with a piece of crystalline mineral such as galena. It needs no battery or power source and runs on the power received from radio waves by a long wire antenna.
