KSLR (630 AM) is a commercial radio station in San Antonio, Texas. It is owned by the Salem Media Group and airs a Christian talk and teaching radio format. The studios and offices are on McAllister Freeway in San Antonio. Current station staff includes Chad Gammage - General Manager, Chris Lair - Operations Director, and Barry Besse - Program Director & Morning Ministry Host.

KSLR transmits with 5,000 watts by day, but at night when radio waves travel farther, it reduces power to 4,300 watts. It uses a directional antenna at all times. The transmitter and four-tower array are off Rigsby Avenue (U.S. Route 87) in China Grove.[2]


KSLR airs shows from national religious leaders such as Greg Laurie, Chuck Swindoll, David Jeremiah, Alistair Begg, Jim Daly, J. Vernon McGee and John MacArthur. Several local San Antonio pastors are also heard. Hosts buy time on KSLR to air their programs and seek donations for their radio ministries.
