* The 1976 nonfiction book CB Bible includes glitch in its glossary of citizens band radio slang, meaning " an indefinable technical defect in CB equipment ", indicating the term was already then in use on citizens band.

It does not suffer the interference effects found on citizens ' band ( CB ) at 27 MHz, or the 49 MHz band also used by cordless phones, toys, and baby monitors.

Prior to the change of CB radio from licensed to " permitted by part " ( FCC rules Part 95 ) status, the typical toy walkie-talkie available in North America was limited to 100 milliwatts of power on transmit and using one or two crystal-controlled channels in the 27 MHz citizens ' band using amplitude modulation ( AM ) only.

Voice procedure includes various techniques used to clarify, simplify, and standardize spoken communications over two-way radios, in use by the military, in civil aviation, police and fire dispatching systems, citizens ' band radio ( CB ), etc.

In 1976 Bob Milsap resurrected the act, at first with a novelty single based on the current CB citizens band radio craze, " Hey Shirley ( This Is Squirrely )", and followed by two albums ( one a Christmas release ).

The song's success helped start a fad for citizens band ( CB ) radio.

The communications equipment may include a multi-band receiver / scanner, a citizens band ( CB ) radio, portable “ walkie-talkies ” with rechargeable batteries, and a portable battery-powered television.

Handle with Care is a 1977 comedy movie set in a small town in Nebraska and loosely based on the wide popularity of citizens ' band radio, usually called " CB ", at the time.

Citizens ' Band radio ( also known as CB radio ) is, in many countries, a system of short-distance radio communications between individuals on a selection of 40 channels within the 27-MHz ( 11 m ) band.

Some countries also have personal radio services in the UHF band, such as the European PMR446 and the Australian UHF CB.

In 1948, the original Class D CB Radios were designed for operation on the 460 MHz – 470 MHz UHF band.

In 1958 the Class D CB service was moved to 27 MHz, and this band became what is popularly known as CB.

Part 95 of the Code of Federal Regulations regulated the Class D CB service, on the 27 MHz band, as of the 1970s.

Most of the 460 – 470 MHz band was reassigned for business and public-safety use ; Class A CB is the forerunner of the General Mobile Radio Service ( GMRS ).

Originally, there were 23 CB channels in the U. S .; the 40-channel band plan was implemented in 1977.

Initially, the FCC intended for CB to be the " poor man's business-band radio ", and CB regulations were structured similarly to those regulating the business band radio service.

At that time in Australia, the 11-meter band was still used by licenced ham operators, but not yet available for CB use.

Citizens Band radio ( often shortened to CB radio ) is a system of short-distance radio communications between individuals on a selection of 40 channels within the 27-MHz ( 11 m ) band.

This was unacceptable to the CB lobby partly because the low power would give a short range but mainly because the cost of equipment to operate in this band would be prohibitive.

The CB lobby continued to insist that any CB system had to use the ( US ) 27 MHz band, be AM and a maximum output power of 4 watts ( i. e. the US system ).

CB was eventually legalised on a 27 MHz band but not the band used in the US.

In a related way, some CB enthusiasts took up long-distance communication in a narrow frequency band around 6. 6 MHz, using SSB mode.

This unofficial ' band ' was close to international air travel frequencies and policed more strongly than normal CB radio but reached well into European countries and did not suffer from the high levels of interference on 27 MHz.

In fact, the cost of cutting edge ( at the time ) UHF radio equipment meant that only the more serious CB operator would use the band, a nice though expensive haven for mature CB operators, and radio hams who didn't like the ' red tape ' of amateur radio.

The CB lobby was appeased, until they saw the fine print – the new 27 MHz band used an odd channel offset and frequency modulation, so it was incompatible with the American system.

Radio amateurs using the 28 MHz ten-metre band were particularly offended by CB radios that could transmit into their frequency band.

An example of a transceiver would be a walkie-talkie, or a CB radio.

The film Convoy, inspired by a 1975 song of the same name, explores the camaraderie between truck drivers, where the culture of the CB radio encourages truck drivers to travel in convoys.

Other notable guest stars included: Cesar Romero as Chico's absentee father ; Tony Orlando as Chico's look-alike, the ex-fiance of a hostile woman he wants to date ; José Feliciano, who wrote the theme song, as Chico's womanizing famous-singer cousin Pepe Fernando ; Sammy Davis Jr. as himself ; Herbie Faye appeared as Bernie in the 1975 episode " Louie's Retirement "; Shelley Winters ( reuniting with Albertson, with whom she'd costarred in The Poseidon Adventure ) as the owner of the local bakery, Shirley Schrift ( her real name ); Jim Backus as Ed's friend who uses him as a " beard "— pretending to be playing cards with him when cheating on his wife ( Audra Lindley ); silent-film actress Carmel Myers as a former star who has fallen on hard times, brings in her car for repairs, and stays in the garage while looking for work ; George Takei as Ed's supposed long-lost son from his time in Japan during World War II ; Cesare Danova as Aunt Connie's Spanish aristocrat boyfriend, the Count de Catalan, in the second episode in which she appeared ; comedian Joey Bishop as an inept robber ; Bernie Kopell as a plastic surgeon ; Rose Marie as a CB radio enthusiast with whom a lonely Ed connects on New Year's Eve ; Penny Marshall, as a waitress ; football star Rosey Grier as himself, Della's date for a charity benefit dance ; Larry Hovis as a customer in the second episode of the first season ; and Jim Jordan ( of radio's Fibber McGee and Molly ) as a mechanic who used to be a big businessman, until he was victimized by his own company's retirement-age mandate ).

In many countries CB operation does not require a license, and ( unlike amateur radio ) it may be used for business or personal communications.

There were two classes of CB radio: A and B.

An unsuccessful petition was filed in 1973 to create a Class E CB service at 220 MHz, which was opposed by amateur radio organizations and others.

CB radio was used ( especially by truckers ) to locate service stations with better supplies of fuel, to notify other drivers of speed traps, and to organize blockades and convoys in a 1974 strike protesting the new speed limit and other trucking regulations.

McCall's " Convoy " ( 1975 ) and on television series such as Movin ' On ( debuted 1974 ) and The Dukes of Hazzard ( debuted 1979 ) established CB radio as a nationwide craze in the USA in the mid-to late 1970s.

Rules on authorized use of CB radio ( along with lax enforcement ) led to widespread disregard of the regulations ( notably in antenna height, distance communications, licensing, call signs and transmitter power.

He appeared in an interview ( with clips having fun talking to children on his home CB radio station ) in the NBC Knowledge television episode about CB radio in 1978.

As on the internet, CB radio sometimes encouraged the worst characteristics of anonymity:

CB radio is still used by truck drivers, and remains an effective means of obtaining information about road construction, accidents and police radar traps.

In addition, a new alternative to CB radio is the use of smartphone apps, such as Virtual Walkie Talkie, developed by Ando IX for Android phones.
