What is the transceiver CB?

Radio or transceiver CB) Citizen (CB) is a two -way communication device that individuals operate on approved frequencies in different countries. The technology was established in the United States in 1945, when the Federal Communication Commission (FCC) officially approved the frequency band for CB transmissions. In the sixties, CB became a popular accessory to most long -distance truckers who transported goods across the country, and also spread to other businesses and countries. The ranges are used in other countries. The use of CB radio in most cases does not require a broadcast license. It is open to personal or business use and is based on a simplex system where the unit can only transmit when there is no one else, and cannot transmit and accept Songnals simultaneously. The European Union in general, Canada and the United Kingdom have similar systems. They also have Asian nations such as Indonesia and Malaysia, and Australia in 1980.

Social changes in the United States at the beginning of the 70th years drove the purpose of CB transceiver to higher heights, when the Arab oil embargo from October 1973 to March 1974 made expensive and rare in the US. This led to an increased level of air traffic transceiver CB between truckers and other small businesses that relied on fuel to survive. They shared the location of open fuel stations and speed traps according to law enforcement, as the reduced speed limit on federal motorways in 1973 also entered into force to support protection. Transport businesses that are responsible for most of the movement of goods in the United States are day -long for fast transit and easily accessible fuel for profit.

At the end of the 1960s and early 1970s, types of transceivers were more portable because progress in electronics in a solid state meant that they could be installed in cars,on motorcycles and more. Progress in technology in recent years has also reduced the use of CB transceiver because it is replaced by more convenient communication methods such as mobile phones and wireless internet services. The design of the Simplex transceiver CB does not work well when it is difficult to operate at the frequency, because at once only one person can speak. This has led to a decrease in the use of the CB transceiver, although most of the contrary truckers still have active units installed in their cabins for emergencies.
