Citizens band radio also known as CB radio is, in many countries, a system of short-distance radio communications between individuals typically on a selection of 40 channels within the 27 MHz 11 m band. In many countries, CB operation does not require a license, and unlike amateur radio it may be used for business or personal communications.

Like many other two-way radio services, citizens band channels are shared by many users. Only one station may transmit at a time; other stations must listen and wait for the shared channel to be available.

It is customary for stations waiting to use a shared channel to broadcast the single word "Break" followed by the channel number, updating dog microchip information a lull in the conversation. A number of countries have created similar radio services, with varying technical standards and requirements for licensing.

Although licenses may be required, eligibility is generally simple. The citizens band radio service originated in the United States as one of chat personal radio services regulated by the Federal Communications Commission FCC.

These services began in to this web page citizens a radio band for personal communication e. Class B radios had simpler technical requirements, and were limited to a singles frequency range. Al Gross established the Citizens Radio Corporation during the late s to manufacture Class B handhelds for the general public. Ultra-high frequency UHF radios, at the time, were neither dating nor affordable for the average consumer.

There were only 23 channels at the time; the first 22 were taken from the former amateur radio service meter greek, and channel 23 was shared with radio-controlled devices.

Some hobbyists continue to use the designation "11 meters" to refer to the Citizens Band and adjoining frequencies. There are several other classes of personal radio services for specialized purposes such as remote control devices. During the s, the service was popular among small businesses e. By the late s advances in solid-state electronics allowed the weight, size, and cost of the radios to fall, giving the public access to a communications medium previously only available to specialists.

After the oil crisis the U. CB radio was used especially by truckers to locate service stations with better supplies of fuel, to notify other drivers of speed trapsand to organize blockades and convoys in a strike protesting the new speed limit and chat trucking regulations. One leader was able to almost single-handedly coordinate an interstate highway blockade of hundreds of tractor-trailers in eastern Pennsylvania using the citizens band radio in his truck. His name was J.

Edwards and his "handle" on air nickname was "River Rat". The blockade began on I and quickly spread throughout the country, with River Rat's messages literally being relayed from one area of trucks to the next. McCall 's " Convoy "[10] providing inspiration for songs like Breaker-Breaker from the Outlaws and truckers legendary, and on television series such as Movin' On debuted in and The Dukes of Hazzard debuted established CB radio as a nationwide craze in the United States in the mid- to late s.

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 Similar to internet chat rooms a quarter-century later, CB allowed gippsland to get to know one another in a quasi-anonymous manner.

As with the internet, CB radio usage allowed the worst characteristics of anonymity. Originally, there were 23 CB channels in the U.

Several people had 22A, but not many had 22B. Channel 9 was officially reserved for emergency use by the FCC in Many CBers called channel 19 "the trucker's channel". Channel 11 was originally restricted by the FCC for use as the calling channel. The original FCC output power limitation for CB radios was "5 watts DC input to the final amplifier stage", which was a reference to the earlier radios equipped with tubes.

With solid state radios becoming more common in the s, registration specification was rewritten by the FCC at the same time the authorized channels were increased to The current specification is simply "4 watts output AM or 12 watts output SSB " as measured at the antenna connector on the back of the radio.

The old specification was often used in false advertising by some manufacturers who would claim their CB radios had "5 watts" long after the specification had changed to 4 watts output.

The older channel radios built under the old specifications typically had an output of around 3. The FCC simply rounded up the old "5 watts DC input to the final amplifier stage" specification to the new "4 watts output as measured at the antenna connector on the back of the radio", resulting in a far simpler and easier specification.

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.

Until[13] only channels and 23 [14] could be used for "interstation" calls to other licensees. Channels and were reserved for "intrastation" communications among units with the same license. It was common for a town to adopt an inter-station channel as its "home" channel. This helped prevent overcrowding on Channel 11, enabling a CBer to monitor a town's home channel to contact another CBer from that town instead of a making a general call on Channel Business caught on to this market, and introduced marine CBs containing a weather band WX.

There was a lot of controversy about whether or not the Coast Guard should monitor CB radio, but they did, using Motorola base stations installed at their search and rescue stations. CB has lost much of its original appeal due to development of mobile phonesthe internet and the Family Radio Service.

Changing radio propagation for long-distance communications due to the year sunspot cycle is a factor at these frequencies. In addition, CB may have become a victim of its own popularity; with millions of users on a finite number of frequencies during the mid-to-late s and early s, channels often were noisy and communication difficult.

This caused a waning of interest among hobbyists. Business users such as tow-truck operators, plumbers and electricians moved to the VHF business-band frequencies. The business band requires an FCC license, and usually results in an assignment to a single frequency.

The advantages of fewer users sharing a frequency, greater authorized output power, clarity of FM transmission, lack of interference by distant stations due to "skip" propagation, and consistent communications made the VHF Very High Frequency radio an attractive alternative to the overcrowded CB channels. Channel 9 dating restricted by the FCC to only emergency communications and roadside assistance.

CB radio is still used by truck drivers, and remains an effective means of obtaining information about road construction, accidents and police speed traps. At that time in Australia, the meter band was still used by licensed ham operators and Emergency Services, [21] but not yet available for CB use. A number of CB clubs had formed by this time which assigned call signs to members, exchanged QSL cardsand lobbied for the legalisation of CB. The new RB regulations came in on January 1, and the last official registration date for channel sets was January 31, After this date, use of unregistered channel CB sets was deemed illegal and unlicensed sets were no longer be eligible to be licensed.

The 18 channel band plan used 16 channels of the 23 channel CB radios plus 2 extra channels, namely The original channels 1,2,3,4,10,21 and 23 were deleted from the 18 channel band plan. So channel 1 on an 18 channel was actually channel 5 on a 23 channel radio. 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 and by the end of the first quarter of there had been an estimatedlicences issued Australia's Population in was The regulations called for one licence per CB radio. UHF is Mhz, with an output power of 5 Watts. Australians refer to heavy transport drivers as "Truckies", a local variation article source the American term "Truckers".

In IndonesiaCB radios were first introduced about when some transceivers were imported illegally from Australia, Japan and the United States. The dates are hard to confirm accurately, but early use was known around large cities such as JakartaBandungYogyakartaSurabaya and Medan. The frequency band is HF, Channel 9 is reserved for emergencies, and channel 11 is a calling channel.

Channel 9 is reserved for emergencies, and channel 11 for calling. A short-range simplex radio communications service for recreational use is from Frequencies for Digital PMR are from In the UK, small but growing numbers of people were illegally using American CB radios during the late s and early s.

The power-reduction switch is also useful in reducing TV interference. MPT also restricted antennas to a maximum length of 1. Over the next several years antenna regulations were relaxed, with antenna length increasing to 1.

On September 1, the UK added the usual 40 frequencies Persons using illegal equipment or accessories still risk prosecution, fines or confiscation of equipment, although this is rarely enforced. AM and SSB on the freeband and amplifier use are common among enthusiasts. Packet radio is legal in the UK, although not widely used. Although the use of CB radios in the Registration is limited they are still popular, especially with the farming community, truckers and mini-cab services.

The normal calling and truckers' channel is channel 19, although many truck organisations and groups use other channels to avoid gippsland. CB radio is not a worldwide, standardized radio service.
