KTRH (740 AM) is a commercial radio station licensed to Houston, Texas. It airs a news/talk radio format and is owned by iHeartMedia, Inc. Its studios are along the West Loop Freeway (I-610) in the city's Uptown district. The transmitter site, a four-tower array, is in unincorporated Liberty County, off Cox Road in Dayton.[2] KTRH is one of the oldest radio stations in the United States, first licensed to Austin on April 22, 1922. Programming is also heard on co-owned KODA's HD 2 subchannel at 99.1 MHz, and on the iHeartRadio platform. KTRH is Southeast Texas' primary entry point station for the Emergency Alert System.
KTRH broadcasts with 50,000 watts around the clock, the highest power permitted by the Federal Communications Commission for commercial AM stations. But because it transmits on AM 740, a Canadian clear channel frequency, the station uses a directional antenna to protect Class A station CFZM in Toronto. During the day, the station provides at least secondary coverage to most southeast Texas, as far west as Austin and San Antonio and as far north as College Station and Lufkin, as well as much of southwestern Louisiana. At night, to protect CFZM, the station switches to a directional pattern with a significant null to the east, concentrating the signal in Houston, the Golden Triangle and Victoria.
