Operating with a massive 50,000-watt clear-channel signal, AM 740 Houston—known on air as NewsRadio 740 KTRH—stands as a heavyweight in Texas media. Owned by iHeartMedia, this station blankets Southeast Texas with continuous news, weather updates, traffic reports, and conservative talk programming. From morning drive-time updates to late-night syndicated broadcasts, understanding how this powerhouse operates reveals a lot about regional media influence.
For decades, the station has served as the primary entry point for emergency alerts across the region while shaping local political conversations. Whether you're tracking daily commutes or following breaking Texas headlines, looking at the history, lineup, and signal mechanics explains why this frequency remains a staple for millions of listeners.
The Technical Powerhouse: Signal and Coverage
You can't talk about AM 740 Houston without looking at the physics behind its reach. Operating at 740 kHz on the AM dial, KTRH holds a coveted clear-channel allocation. This classification means the station operates with high power—specifically 50,000 watts—allowing its signal to travel massive distances, particularly after sunset when AM radio waves bounce off the ionosphere.
- Daytime Coverage: Blankets the entire Greater Houston metropolitan area and stretches deep into surrounding counties.
- Nighttime Reach: Reaches across multiple U.S. states and parts of the Gulf of Mexico under favorable atmospheric conditions.
- Backup Platforms: Simulcasts on digital streams via the iHeartRadio platform and select HD subchannels to combat urban electrical interference common on the AM band.
According to the Federal Communications Commission, AM broadcasting relies heavily on groundwave propagation during daylight hours, which explains why high-wattage stations like KTRH maintain such a dominant footprint across flat terrain like the Texas Gulf Coast.
Core Programming and On-Air Lineup
The station relies on a blend of aggressive local reporting and high-profile syndicated conservative talk. This dual approach keeps listeners tuned in throughout the workday.
Morning Drive and Local News
Weekdays kick off with Houston's Morning News, anchored by Jimmy Barrett. This block focuses heavily on local breaking stories, regional politics, real-time traffic updates, and economic developments specific to Harris County and beyond.
Midday and Afternoon Talk Heavyweights
Following the morning block, the schedule shifts toward personality-driven commentary and national political discourse:
- The Michael Berry Show: A staple of Texas talk radio known for sharp social commentary and regional cultural insights.
- National Syndication: Airing major programs including The Clay Travis and Buck Sexton Show and The Sean Hannity Show.
History and Evolution of the Frequency
The station's roots stretch back nearly a century. First licensed in April 1922, KTRH moved to the 740 kHz frequency in 1942 following major federal reallocation of North American radio bands. Over the decades, it transitioned from a general-interest CBS affiliate into a dedicated news-and-talk format.
Throughout major historical events—from twentieth-century space race milestones in Houston to modern natural disasters like Hurricane Harvey—the station has functioned as a critical communication lifeline.
