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. 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.

from the outset, the government attempted to regulate cb radio with license fees and call signs, but eventually they abandoned this approach. enthusiasts rushed for licences when the doors opened at post offices around australia in mid-1977 and by the end of the first quarter of 1978 an estimated 200,000 licences were issued (australia's population in 1978 was 14.36 million). the regulations called for one licence per cb radio. the price for a licence in 1977 was au$25 per year (in mid 1977 the australian dollar exchange rate was au 90 cents to us $1), a not insubstantial amount for the average australian wage-earner. australian cb radio uses am, usb, and lsb modes (no fm) on 27 mhz, allowed output power being 4 watts am and 12 watts ssb. when uhf cb was first legalised the 27 mhz cb band was intended to be closed to australian cbers in 1982 and only the 477 mhz uhf band was to continue, but this did not eventuate. the first 477 mhz cb radio in 1977 was designed and made in australia by philips and was a 40 channel cb called the fm320.
