KJJF (88.9 FM) is a National Public Radio member station in Harlingen, Texas, United States. KJJF, with its transmitter located in Lozano, signed on the air in April 1991 as KMBH-FM and began airing NPR programming in June of the same year. KMBH-FM's signal was limited mainly to Cameron County, Texas until July 1992, when satellite station KHID 88.1 FM McAllen began broadcasting with its transmitter located in Alton, covering the Hidalgo County area.
On April 3, 2015, RGV Educational Broadcasting announced that it would change KMBH-FM's call letters to KJJF effective April 7th. The new call sign honors RGV Educational Broadcasting founder Bishop John Jacob Fitzpatrick; it also distinguishes the radio station from former sister station KMBH television, which was sold to R Communications several months earlier.
