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. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena. This component is now called a diode. WebTo make a crystal radio coil, you need 26 SWG, which is 0.4572 mm, or 0.018 inches. You can get this from almost all electronics stores. Although this type of coil works best, it does not perform as well as a proper radio …
