Full Description
Citizens band radio (CB radio), used in many countries, is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or shortwave band. Citizens band is distinct from other personal radio service allocations such as FRS, GMRS, MURS, UHF CB and the Amateur Radio Service ("ham" radio). In many countries, CB operation does not require a license, and may be used for business or personal communications.
The term "QSL" comes from the international Q code and means "I confirm receipt of your transmission". A QSL card is therefore a written confirmation. The sending of QSL cards dates back to the 1920s when AM radio broadcasts were still a novelty and stations wanted to know how far away they were being received.
