what year did the cb radio come out
Citizens band radio The citizens band radio service originated in the United States as one of several personal radio services regulated by the Federal Communications Commission (FCC). These services began in 1945 to permit citizens a radio band for personal communication (e.g., radio-controlled model airplanes and family and business communications). In 1948, the original CB radios were designed for operation on the 460–470 MHz UHF band.[3] There were two classes of CB radio: "A" and "B". Class B radios had simpler technical requirements, and were limited to a smaller frequency range. Al Gross established the Citizens Radio Corporation during the late 1940s to manufacture Class B handhelds for the general public.[4]
FM broadcasting in the UK The UK government is planning for a switchover from FM to digital radio once take-up and coverage meets certain criteria. Successive Governments have admitted that FM VHF Band II analogue radio would not cease until the majority use digital, so no actual date has ever been agreed. Digital listening figures however consistently include Satellite, DTT and online streaming, not just DAB. In any case there is a commitment to maintain community FM Radio. This means that as long as there are significant numbers of listeners on FM in the United Kingdom no government is likely to take the politically unpopular decision to turn off analogue. Support for the FM Switch Off in the UK is limited.[citation needed]
