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. 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. How to make a batteryless (crystal set) radio ... CRYSTAL SET. The simplest radio receiver, known as a Crystal Set, consists of nothing more than a coil, tuning capacitor, diode detector, and a pair of earphones. Basic Technology of Quartz Crystal Resonators 4timing Home Up Quartz Crystal Technology Oscillator Technology MCF Technology Manufacturing: Basic Technology of Quartz Crystal Resonators. Quartz crystal resonators (often called “crystals”) are widely used in frequency control applications because of their unequalled combination of high Q, stability, small size and low cost. Crystal Radio Page A Set with a FET and a LM386 Amplifier. My latest set uses a Schottky diode, a FET and a LM386 audio amplifier. It has minimum loading on the tuned circuit for maximum selectivity. Dave's Crystal Radio Set DX Notes Page DX Crystal Set Building Notes. In writing this page, my first thought was to call it "conclusions". Conclusions is such a final sounding word and while these are my conclusions, I better be careful about calling them final. Building a crystal radio set OpenLearn Open University A crystal set is the most basic type of radio receiver. It is capable of receiving AM (amplitude modulated) transmissions, which are generally found on the long, medium and short wave bands. Crystal oscillator A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric resonator, a crystal, as its frequency determining element. Crystal is the common term used in electronics for the frequency determining component, a wafer of quartz crystal or ceramic with electrodes connected to it.
