Crystals In Radio. These days the envelope detector is a point contact diode such as a 1n34. Hundreds of crystal radio circuits were designed to improve tuning selectivity without loss of sensitivity. In modern radio equipment, there usually is a single crystal, soldered to the circuit board, that serves as the timebase for a. As this resonant phenomenon is repeatable and stable over time, a properly utilized crystal can be the basis of a frequency standard. A crystal radio is basically a high q resonator tied to an antenna and an envelope detector. From a lower frequency, the crystal is ground down (gross error) or acid etched (fine error) until the desired frequency of operation is reached. A lot of this work. There was a time when anyone involved with radio transmitting — ham operators, cb’ers, scanner enthusiasts, or remote control model fans — had a collection of crystals. The hidden magic of crystal radios is that they’re able to capture almost infinitesimal amounts (nanowatts to microwatts) of power from distant transmitter stations and efficiently convert it to sound for our ears.
