Crystal Set Talking Electronics Everyone wants to make a RADIO. The simplest radio is a CRYSTAL SET. (Sometimes called a Crystal Set Radio or Xtal Radio Set or Crystal Diode Radio.) Crystal radio A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio. It uses only the power of the received radio signal to produce sound, needing no external power. Crystal Radio Circuits techlib The circuit is quite simple but many pitfalls await the novice. The first precaution is most important! The crystal radio works best with a long, high outdoor antenna but the beginner may not fully appreciate the danger of bringing such a wire into the house.
