KWJB (Arizona)
KWJB was the call sign for several radio stations in Globe, Arizona. Two separate licenses on the 1240 kHz frequency, and an FM station on 100.3 MHz, used the call letters. The first KWJB signed on in 1938, being joined by the FM station in 1958. After going silent October 29, 1960, the licenses of both stations were ordered revoked by the Federal Communications Commission (FCC) in 1961 along with all other stations owned by Gila Broadcasting. A second AM station in Globe on the same frequency, but a different license, operated as KWJB between 1969 and 1975. History Original KWJB The Sims Broadcasting Company put KWJB on the air in the summer of 1938, broadcasting on 1210 kHz. In 1939, KWJB joined KTAR's Arizona Broadcasting Company (ABC) network as part of the latter's expansion from two stations to five. Broadcasting initially as a daytime-only station, it was approved for unlimited operation in October 1939 with 250 watts. In March 1940, the station relocated to new studios in ...

Call Sign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi station ...

Radio Stations Disestablished In 1975
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and ...
