How to make a batteryless (crystal set) radio ... 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. A typical circuit diagram for a Crystal Set Radio is given below where inductor or coil L1 is tuned by variable capacitor VC1 to the transmitter frequency. Crystal Radio Circuits | Crystal Set Circuits ... In reality there may have been little to choose between the different crystal radio circuits, but each one optimised the performance in a different way. Basic crystal radio circuit. The circuits for crystal sets could be very simple. Some simply employed a tuned circuit, a crystal detector and a pair of headphones. 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. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena.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.

The antenna, of course, captures the radio waves travelling through the air and converts them into alternating current. In order for current to flow, a […] 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. An FM Crystal Set Electron Bunker The low R 0 would normally make them a bad choice as a crystal set detector (galena aficionados notwithstanding). However, it appears that this particular resonator circuit has a very low resonant RF output resistance, which turns out to be a good match to the diodes. For more info on this, see Article #4 on Ben Tongue's site. This low RF ...

How to Make Build a Crystal Radio Step by step instructions for making a tunable crystal radio. This is a radio that gets its power from the radio waves. I made it almost entirely from junk except for the diode (1N34 germanium ... If you are like me, you may have arrl.org High Sensitivity Crystal Set Build a “crystal radio” that does not require an outside antenna or ground by using a new zero voltage threshold MOSFET. Bob Culter, N7FKI the circuit topology, which was motivated by a similar circuit using a JFET and battery gate bias configuration developed by David W. Cripe, NE4AM (formerly KC3ZQ).4 The Build an Antique Style Crystal Radio: 9 Steps (with Pictures) A crystal radio, or crystal set as it is sometimes called, is a radio that only uses the power of the radio waves picked up by the antenna to generate the sound heard in the head phones. The reason it is called a crystal set is because they use a mineral crystal as a diode for the detector in the circuit.
