The success of transistor radios led to transistors replacing vacuum tubes as the dominant electronic technology in the late 1950s. [28] The transistor radio went on to become the most popular electronic communication device of the 1960s and 1970s. Billions of transistor radios are estimated to have been sold worldwide between the 1950s and ...
A Soviet clone of this radio is called Saratov, named after the city where it was manufactured. While being similar externally, it is fully different internally. It is a nine-transistor TRF receiver with transformerless audio amplifier, while the prototype is a six-transistor superheterodyne, and its audio amplifier uses transformers.
The Toot-a-Loop Radio or Panasonic R-72 was a novelty radio made by Panasonic Japan in the early 1970s. This radio was designed to be wrapped around the wrist. It also came with stickers for customizing the unit. Reception was the AM broadcast band only - no FM (the FM version of this radio is called RF-72).
The RCA model R7 Superette superheterodyne table radio. This is a list of notable radios, which encompasses specific models and brands of radio transmitters, receivers and transceivers, both actively manufactured and defunct, including receivers, two-way radios, citizens band radios, shortwave radios, ham radios, scanners, weather radios and airband and marine VHF radios.
The all-transistor car radio was a $150 option. [51] [52] [53] The Sony TR-63, released in 1957, was the first mass-produced transistor radio, leading to the mass-market penetration of transistor radios. [54] The TR-63 went on to sell seven million units worldwide by the mid-1960s. [55]
The rocket radio was also used as an emergency radio, because it did not require batteries or an AC outlet. The rocket radio was available in several rocket styles, as well as other styles that featured the same basic circuit. [38] Transistor radios had become available at the time, but were expensive. Once those radios dropped in price, the ...
