![]() ![]() Following the invention of the transistor in 1947which revolutionized the field of consumer electronics by introducing small but powerful, convenient hand-held devicesthe Regency TR-1 was released in 1954 becoming the first commercial transistor. If you've ever wanted to learn radio from the inside out, here's your chance. The first step of this project is to build the Crystal Radio - Budget Cuts 140 pF, which will involve building the ferrite rod coil, selecting the tuning capacitor, using a suitable germanium diode, and establishing proper earth and antenna. A transistor radio is a small portable radio receiver that uses transistor -based circuitry. The LS is a high-impedance piezoelectric headphone like the vintage 2000 crystal earpiece. But any diode will work, only with less volume. * Image rejection and noise analysis methods Building this is an excellent start in understanding how AM radios work: A crystal AM radio The diode is ideally a germanium diode, like the OA81, as it has a lower forward volt drop. Open the radio by removing all the screws. The only tool you should need is a small screwdriver. This will be a wheel or slider that changes stations. * In-phase, quadrature, and AM broadcast signals The only thing you need for this project is an AM/FM transistor radio, an older model that has a physical adjustment for tuning rather than digital. * Transistor and differential-pair oscillators * Basic and advanced Superheterodyne radios Simple Crystal Radio One-Transistor Amplifier/Detector TL431 Crystal Radio Amplifier Crystal Radio RF Amplifier Very High Gain Crystal Earphone Amplifier.
