You're stuck in 610 South traffic. The sun is beating down on the hood of your truck, and the brake lights in front of you look like a long, angry string of Christmas lights. The game started ten minutes ago. You could try to pull up a choppy stream on your phone and prop it against the dashboard, but we both know that’s a recipe for a cracked screen or a fender bender. Honestly, if you want to listen to Astros game broadcasts the right way, you need to embrace the airwaves. There is something about baseball on the radio that just hits different. It’s the crack of the bat without the sensory overload of flashing digital ads behind home plate. It’s the voice of Robert Ford and Steve Sparks painting a picture that’s often more vivid than what you see on a 4K screen.
Radio is the heartbeat of Houston sports. While the TV deals get messy and streaming apps demand another $20 monthly subscription, the radio signal just hangs out there in the atmosphere, waiting for you to grab it.
The Best Ways to Listen to Astros Game Broadcasts Right Now
If you are within a hundred miles of Minute Maid Park, your primary lifeline is KBME 790 AM, better known as Sportstalk 790. They are the flagship. They’ve been the home of the Stros for years, and for good reason. The signal is solid, though it can get a little fuzzy if you’re driving under some of those massive overpasses near the Beltway. When the schedule gets weird—like when there’s a conflict with other major sporting events—the games sometimes flip over to KTRH 740 AM. That 50,000-watt blowtorch of a signal can be heard all the way in Louisiana and deep into Central Texas on a clear night. It’s kinda legendary.
For the Spanish-speaking faithful, TUDN Radio Houston 93.3 FM is where the magic happens. Francisco Romero and Alex Treviño bring an energy that is arguably higher than the English booth. Even if your Spanish is a bit rusty, the excitement in their voices when Yordan Alvarez hammers a ball into the upper deck is universal.
If you aren't near a traditional radio, you’ve basically got two digital paths. The first is the MLB App. Look, it’s not free, but it’s cheap. For about $30 a year (or a few bucks a month), you get the home and away radio feeds for every single team, not just the Astros. The best part? No blackouts for radio. While the TV side of the MLB App is a nightmare of "this content is restricted in your area" messages, the radio feed works everywhere. You can be in the middle of a hiking trail in Oregon and listen to the local Houston broadcast without a hitch.

Then there’s SiriusXM. If you have a satellite subscription, the Astros are usually tucked away in the 170-190 channel range. It’s great for road trips where you’re bouncing between cell towers and local stations are fading into static.
Why Robert Ford and Steve Sparks are Essential
People underestimate how hard it is to call a baseball game on the radio. On TV, the announcer can stop talking for thirty seconds because you can see the pitcher adjusting his cap. On the radio, silence is death. Robert Ford is a pro’s pro. He’s got this smooth, rhythmic delivery that never feels rushed. He gives you the score and the inning every few minutes—which is the most important thing for a listener who just tuned in.
Then you have Steve "Sparky" Sparks. He’s a former big-league knuckleballer, and he sounds like a guy you’d want to grab a beer with at a Crawford Street bar. He’s quirky. He notices the tiny things, like how a pitcher’s grip changed or why a runner took a slightly wider turn at first. Their chemistry is what makes you want to listen to Astros game feeds even when you’re sitting right in front of a television. A lot of fans actually mute the TV and sync up the radio audio, though the delay can be a real pain to manage.
Dealing with the "Digital Delay"
Speaking of delays, we have to talk about the "spoiler" problem. If you are listening via a streaming app like iHeartRadio or the MLB App, the audio is usually 30 to 60 seconds behind the actual live action. If you have "score alerts" turned on your phone, you’ll get a buzz saying "Altuve homers" before you even hear the pitcher wind up. It ruins the moment. Honestly, the only way to get true, real-time play-by-play is an old-school AM/FM transistor radio. It’s instantaneous. No buffering. No lag.

Where to Find the Astros Radio Network
The Houston Astros Radio Network is actually pretty massive. It isn't just a Houston thing. There are dozens of affiliate stations across Texas and Louisiana.
- Beaumont: KLVI 560 AM
- Bryan/College Station: WTAW 1620 AM
- Corpus Christi: KSIX 1230 AM
- Austin: KTXX 104.9 FM (usually)
- San Antonio: KTKR 760 AM
The list changes slightly every season as contracts are renewed, but the core remains the same. Most of these stations carry the full pre-game and post-game shows, too. The post-game call-in shows are where you get the real flavor of the fanbase—the overreactions, the celebrations, and the "fire the hitting coach" rants that make sports talk radio so entertaining.
The Technical Side of the Broadcast
Ever wonder why AM radio still exists? It’s about the wavelength. AM signals travel along the ground (groundwaves) and can bounce off the ionosphere at night (skywaves). This is why you can sometimes pick up listen to Astros game broadcasts on 740 AM while driving through the desert in New Mexico at 11:00 PM. FM radio is "line-of-sight," meaning if there’s a big hill or a building in the way, the signal drops. For a team with a massive geographic footprint like the Astros, AM is still king.
However, the interference is getting worse. Electric vehicles (EVs) are notorious for generating electromagnetic noise that messes with AM reception. In fact, some car manufacturers tried to remove AM radio from their dashboards entirely recently. Thankfully, there was a big pushback from broadcasters and emergency management agencies, so for now, your dashboard is safe. If you’re in a Tesla or a Ford Lightning and the static is unbearable, your best bet is switching to the car’s built-in TuneIn app or CarPlay to stream the flagship 790 AM feed, assuming you have the data.

Is the iHeartRadio App Free?
Yes and no. You can download the iHeartRadio app for free and search for "Sportstalk 790." Most of the time, you can hear the pre-game analysis and local talk shows for free. However, MLB has very strict "geofencing" rules. When the actual first pitch is thrown, the digital stream on iHeartRadio might cut over to national programming or a generic sports feed because they don't have the digital rights to stream the play-by-play for free to everyone.
This is the most frustrating part for fans. You think you’ve found a loophole, and then—bam—as soon as the game starts, the audio switches to a talk show about the NFL. To bypass this, you either need to be within the physical broadcast range of the radio tower or pay for the MLB At Bat subscription.
Making the Most of the Experience
If you’re going to listen to Astros game coverage, do it right. If you’re at the stadium, bring a small pocket radio with earbuds. Minute Maid Park’s Wi-Fi is decent, but the delay on the apps is still there. Watching a play happen in front of you and then hearing the call 40 seconds later in your ear is jarring. But hearing Robert Ford’s voice exactly as the ball hits the glove? That’s pure baseball bliss.
Also, don't sleep on the pre-game show. It usually starts about an hour before first pitch. They go deep into the analytics—pitching matchups, BABIP (Batting Average on Balls In Play), and injury updates—that you won't get from a quick Twitter/X scroll.
Actionable Steps for the Best Audio Experience
- Check your hardware: If you’re using an old-school radio, extend the antenna fully. If you're indoors, place the radio near a window. AM signals are easily blocked by the steel and concrete of modern office buildings.
- Download the MLB App: Even if you don't pay for the premium version, the free version often provides the "Game Day" pitch tracker, which is a great visual aid to have open while you listen to the audio.
- Syncing Audio to TV: If you want to use the radio audio while watching the TV, use a DVR. Pause the TV for a few seconds until the action on the screen matches the sound from your radio or stream. It takes a little trial and error, but it’s worth it to avoid the national TV announcers who might not know the Astros roster as well as the local guys.
- Check the Schedule: Always verify if the game is on 790 AM or 740 AM. On big nights when the Rockets or Texans are playing simultaneously, the Astros often get moved to the "big signal" on 740.
The season is long—162 games is a marathon. You can’t always be in front of a TV. You’ve got kids' practices, grocery runs, and late nights at the office. But as long as you have a way to tune in, you’re never really away from the action. Just find that signal, let the static fade, and listen to the boys of summer do their thing.
