Crystal radios can receive such weak signals without using amplification only due to the great sensitivity of human hearing, [3] [48] which can detect sounds with an intensity of only 10 −16 W/cm 2. [49] Therefore, crystal receivers have to be designed to convert the energy from the radio waves into sound waves as efficiently as possible.
The sound quality of antique radios depends on the technologies used in the set. The type of speaker is the main differentiator, with mains or battery also making a significant difference. All valve sets produce 2nd harmonic distortion, which is fairly euphonic. Some also produce significant 3rd harmonic distortion, which is less pleasant to ...
A transistor radio is a small portable radio receiver that uses transistor-based circuitry. Previous portable radios used vacuum tubes , which were bulky, fragile, had a limited lifetime, consumed excessive power and required large heavy batteries.
Self-oscillation reduced the quality of its reception of an AM (voice) radio signal but made it useful as a CW (Morse code) receiver. The beat signal between the oscillation and the radio signal would produce an audio "beeping" sound. The oscillation of the regenerative receiver could also be a source of local interference.
The KLH Model Eight FM table radio, circa 1960. A table radio is a small, self-contained radio receiver used as an entertainment device. Most such receivers are limited to radio functions, though some have compact disc or audio cassette players and clock radio functions built in; some models also include shortwave or satellite radio functionality.
The Realistic DX-60 is a multiband radio. The radio receives 3 MHz to 27 MHz AM shortwave in three bands, 26.965 MHz through 27.405 MHz HF CB in one band, 540 kHz to 1620 kHz standard AM broadcast in one band, and 87 MHz to 108 MHz monaural standard broadcast FM. The DX-60 existed in two versions, model 12-764 and a nearly identical but ...
A Trans-Oceanic model Y600. Shown on the left is a modern shortwave radio for comparison. The Trans-Oceanic (abbreviated T/O) was a brand of portable radios produced from 1941 to 1981 by Zenith Radio. They were characterized by heavy-duty, high-quality construction and their performance as shortwave receivers. [1] [2]
A radio receiver may be a separate piece of electronic equipment, or an electronic circuit within another device. The most familiar type of radio receiver for most people is a broadcast radio receiver, which reproduces sound transmitted by radio broadcasting stations, historically the first mass-market radio application. A broadcast receiver is ...
