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.
