Crystal radio - Wikipedia

WebA 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 It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena.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 … Web1, and the schematic is shown in Fig. 2. The RF input tank, unlike many simple designs, provides "tracking," in that the input tuned circuit changes frequency when the oscillator is tuned. RF tuning is performed by Dl, and oscillator tuning by D5. Both di- odes are Motorola MV209 varac- tors, which act as voltage- variable capacitors. RF energy is northern lights zoom background gif
