You're stuck in I-70 traffic. The sun is dipping behind the Front Range, painting the sky that weird shade of purple that matches the jerseys, and all you want is to hear the pop of a mitt. This is the classic Colorado experience. For decades, Colorado Rockies baseball radio has been the literal soundtrack of summer in the Mountain West. It’s more than just a broadcast; it’s a constant companion for hikers in the San Juans, ranchers in Greeley, and commuters white-knuckling it through the Mousetrap. But honestly, finding the right frequency or the right stream has become surprisingly annoying lately with all the blackouts and app changes.
Jack Corrigan and Jerry Schemmel. Those are the voices you’re looking for. They’ve got this rhythm that feels like a backyard barbecue. If you grew up listening to Wayne Hagin or the legendary Jeff Kingery, the vibe has shifted a bit, but the DNA is the same. Radio is the only medium that lets you "watch" a game while you’re actually doing something productive—or just staring at the horizon.
The KOA 850 AM Giant: Why It Still Rules
KOA NewsRadio 850 AM is a beast. We’re talking about a 50,000-watt "clear channel" station. Back in the day, that meant you could pick up Rockies games in Nebraska, Wyoming, and even parts of Canada on a clear night. It’s still the flagship. If you’re in Denver, you probably just flip to 850 AM or 94.1 FM and call it a day. It’s easy.
But here’s what most people get wrong about the "network." It’s not just one station. The Rockies Radio Network is a massive web of over 40 affiliates spanning across the West. If you’re in Albuquerque, you’re looking for KABQ. Up in Billings? It’s KREW. The problem is that these local stations sometimes drop the feed for high school sports or local news, which is a total vibe killer in the 8th inning of a tie game.
The signal strength of 850 AM is legendary, but digital interference in modern cars can make it sound like you're listening to a game from the bottom of a well. That’s why the move to FM simulcast on 94.1 was such a big deal for local fans. You get the clarity without the engine hum.
Streaming vs. Terrestrial: The Great Blackout Headache
Let's talk about the elephant in the room. You can't just go to the KOA website and hit "Play" to hear the game. Well, you can, but you'll likely hear a syndicated talk show or a repeat of some national news segment instead of the first pitch. Why? Licensing. MLB is incredibly protective of its digital rights.
If you want Colorado Rockies baseball radio on your phone, you basically have three legitimate paths, and each has its own "gotcha" moment:
- The MLB App (At Bat): This is usually the most reliable. It’s a paid subscription, but it’s cheap—usually around $30 for the whole year. No blackouts for radio. I repeat: no blackouts. You can be sitting in the parking lot of Coors Field and listen to the radio feed on your phone without a hitch.
- TuneIn Premium: Similar to the MLB app, but it often comes bundled with other sports. If you already pay for TuneIn to hear the NFL or Premier League, you're probably covered.
- SiriusXM: Great if you’re on a road trip. The Rockies broadcast is usually tucked away in the 800-range of channels on the app or a specific satellite channel.
Streaming via the iHeartRadio app is a hit-or-miss nightmare. Sometimes the local geo-fencing works, and you get the game. Most of the time, you get a "this programming is unavailable" message that makes you want to throw your phone into the South Platte River.
The Art of the Broadcast: Corrigan and Schemmel
Listening to a game is about the silence as much as the shouting. Jack Corrigan has been at this since 2002, coming over from the Cleveland Indians (now Guardians) era. He’s the steady hand. Jerry Schemmel is the survivor—literally. If you don't know his story, look up United Flight 232. His return to the booth after a brief hiatus a few years ago was one of those rare "everything is right with the world" moments for Rockies fans.
They don't sugarcoat things. When the Rockies' bullpen is melting down in the thin air—which, let's be real, happens—they'll tell you. They understand the physics of Coors Field. They know a "routine fly ball" in sea-level San Diego is a 420-foot home run in Denver. That nuance is what you miss when you listen to a national broadcast.
Why the Spanish Broadcast Matters
We can't ignore the Spanish-language side of things. KNRV 1150 AM has been a staple for the Latino community in Denver. The energy on the Spanish broadcast is often ten times higher than the English side. Even if your Spanish is shaky, listening to a walk-off win called on 1150 AM is an absolute masterclass in sports passion. It captures a different side of the Colorado fan base that is just as deep-rooted as the folks who remember the 1993 inaugural season.
Dealing With the "Coors Field Effect" on Radio
Radio guys have the hardest job in Denver. On TV, you see the ball screaming toward the gap. On Colorado Rockies baseball radio, the announcer has a split second to judge if a ball is caught at the track or landing in the fountains.
Because the air is thin, the ball carries differently. It travels roughly 9% further than at sea level. Announcers have to recalibrate their brains. You’ll often hear a bit of hesitation in a call—"Back to the wall... it might be... it is gone!" That’s not a lack of skill; that’s the reality of a stadium where the laws of physics are more like suggestions.
Actionable Steps for the Best Listening Experience
If you’re serious about catching every pitch this season without losing your mind, follow this hierarchy.
First, buy a cheap, portable AM/FM radio with an analog tuner. I’m not kidding. Digital tuners in phones and cars are fine, but a dedicated radio (like a Sangean or a Sony) will pick up 850 AM from incredible distances with zero lag. Remember, streaming audio is usually 30 to 60 seconds behind the actual action. If you're following a live box score on your phone while listening to a stream, you'll see the "Strikeout" notification before the pitcher even winds up on your audio feed.
Second, if you're a cord-cutter, just spring for the MLB At Bat audio-only sub. It’s the price of two beers at the stadium and covers the entire season. It works on CarPlay and Android Auto, which solves the "I-70 commute" problem instantly.
Third, bookmark the official MLB Affiliate Map. Stations change owners or formats every single year. A station that carried the Rockies in Grand Junction last year might be a country station this year. Checking the list in April saves you twenty minutes of frustrated scanning while you're driving.
Lastly, pay attention to the pre-game show. KOA starts their coverage usually an hour before first pitch. It’s some of the best tactical analysis you’ll get, often featuring interviews with Bud Black that are way more candid than the post-game soundbites.
Radio isn't a dying medium for baseball. It’s the purest way to consume the game. It forces you to build the stadium in your own mind. When you're listening to the Rockies on a warm July night, and you hear the crack of the bat followed by the roar of the crowd through that tiny speaker, it doesn't matter if they're 20 games under .500. It just feels like home.
