KTSA (550 AM "107.1 and 550 KTSA") is a commercial radio station in San Antonio, Texas. KTSA is owned by Alpha Media and airs a talk radio format. The studios, offices and three-tower transmitter are on Eisenhauer Road in San Antonio. Most hours begin with world and national news from ABC News Radio. Weekdays feature mostly local talk hosts by day, with some syndicated shows in afternoons and nights, including Dave Ramsey, Lars Larson, Dana Loesch and Red Eye Radio. Weekends include programs on money, health, home repair, cars, gardening and pets. Some weekend shows are paid brokered programming. FM Translator KTSA programming can also be heard on FM translator K296GK at 107.1 MHz. Since KTSA is a Class B station broadcasting with 5,000 watts twenty four hours per day, the FM translator doesn't necessarily improve coverage, but it does afford listeners the ability to listen to high fidelity sound on the FM band. History Early Years KTSA was first licensed, with the sequentially assigned call sign WCAR, signing on the air on May 9, 1922. It was owned by John C. Rodriguez's Alamo Radio Electric Company at 608 West Evergreen Street. (Before January 1923, radio stations in Texas were given call letters beginning with W.) WCAR was the first licensed radio station in San Antonio, however it was the second to begin broadcasting, taking the airwaves shortly after the short-lived San Antonio Express station, WJAE, debuted on August 5. WCAR was initially assigned to the sole available "entertainment wavelength" of the time, 360 meters (833 kHz), which required it to establish a time-sharing agreement with the other local stations. A schedule published on August 16, 1922 covering the next five days reported that WCAR and WJAE had an evening broadcast slot of one hour each. In late 1924 WCAR was reassigned to 1140 kHz. The call sign changed from WCAR to KTSA in early 1927, reflecting the slogan "Kum To San Antonio", and later that year the station was assigned to 1130 kHz. On November 11, 1928, with the implementation of the Federal Radio Commission's (FRC) General Order 40, KTSA was assigned to 1290 kHz on a time-sharing basis with KFUL in Galveston. KTSA's full-time operation began on April 29, 1933, after the FRC approved WCAR's purchase and shutting down of KFUL. In 1935, KTSA moved to 550 kHz, increasing its daytime coverage area by going from 1,000 to
