Citizens Band Radio

Citizens Band Radio

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. Citizens' Band is distinct from the FRS, GMRS, MURS and amateur ("ham") radio. 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.

A number of countries have created similar radio services, with varying technical standards and requirements for licensing. While they may be known by other names, such as the General Radio Service in Canada, they often use similar frequencies (26 to 28 MHz), have similar uses, and similar technical standards. Although licenses may be required, eligibility is generally simple. Some countries also have personal radio services in the UHF band, such as the European PMR446 and the Australian UHF CB.

    The hills and waters o’er,
    When a band of exiles moored their bark
    On the wild New England shore.”

    “Denouement to denouement, he took a personal pride in the
    certain, certain way he lived his own, private life,
    but nevertheless, they shut off his gas; nevertheless,
    the bank foreclosed; nevertheless, the landlord called;
    nevertheless, the radio broke,

    And twelve o’clock arrived just once too often,”
    —Kenneth Fearing (1902–1961)
