Following World War II, after the Federal Communications Commission lifted its freeze on new radio stations, chiropractor, preacher, and rancher Ben Parker and his wife, Mona Parker, both veteran broadcasters, helped form the Atascosa Broadcasting Co. in 1949. On May 8, 1951, the FCC granted a permit for a station in Pleasanton and had previously issued the requested call sign KBOP, inspired by the term “Bop” associated with what would become Rock and Roll. KBOP offered news, music, and entertainment tailored to a predominately rural South Texas listenership. It first broadcast daily from a studio at the transmitter site on the Parkers’ ranch northwest of town and later from studios in Pleasanton. The station primarily served listeners in the surrounding area, including Atascosa, Wilson, McMullen, and Bexar counties. It became an important venue for country music and alternated that with Spanish-language programming largely ignored by other stations. The Parkers hired and mentored many announcers and musicians. In 1976, they sold the station, which later moved to San Antonio under new call letters and formats. The tower and transmitter built by Mona Parker, the first woman in the U.S. to earn an FCC first class engineering license, still operates at its original location, and the control board used for KBOP’s on-air programming was later displayed in the Longhorn Museum founded by the Parkers. Though the station has been off the air for many years, its call letters still evoke memories and stories from former listeners.
