550 KTSA

550 KTSA San Antonio's source for national, international, and local news. KTSA (550 AM) is a News-Talk formatted radio station in San Antonio, Texas. R.

The radio station began as WCAR, founded by John C. Rodriguez of the Alamo Radio & Electric Company in September, 1922. WCAR was the second radio station in San Antonio, taking the airwaves shortly after WJAE which only lasted a few months. For a time the Express News Corporation owned the station. In the 1950s rock and roll radio Pioneer Gordon McLendon bought KTSA and made it one of the first To

p 40 stations in America. KTSA became an overnight sensation because of the music and outrageous for the time promotions including a "Flagpole" sitter in the O. Mitchell Dodge Used Car lot on Broadway, and the KTSA Easter Egg Hunt which swamped San Pedro Park with thousands of listeners searching for a $1000 KTSA Golden Egg. McLendon sold KTSA in the 1960s but the station remained one of San Antonio's most listened-to stations until the advent of FM stereo radio. KTSA was a Top 40 format "55-KTSA" until Fall 1986 when it changed to News/Talk format that it is today. Current Lineup:

KTSA Morning News w/ Trey Ware -- 5a-7a
Ware and Rima -- 7a-9a
