The Mechanics Behind the Reds' Radio Coverage

The Cincinnati Reds Radio Network has been operating since 1919, which makes it one of the oldest continuous sports radio networks in the United States. It runs on a straightforward model: one flagship station, dozens of affiliates, and enough technical infrastructure to push game audio from Cintas Center to listeners who are sixty miles away. What looks like simplicity on paper is actually a fairly complex logistics operation. The flagship is WLW 700 AM in Cincinnati, and everything flows out from there. Games are produced at the ballpark with dedicated broadcast equipment, then fed through a mix of satellite and audio-over-IP feeds to affiliate stations. Each affiliate decides whether to carry the main feed, run their own announcers, or rebroadcast part of the game locally. That last option is where things get messy.

How 21 Stations Keep the Faith Across Three States

The network currently operates through approximately 21 affiliate stations spread across Ohio, Kentucky, and Indiana. These aren't all full-power stations. Some are low-power FM translators. A few are AM clear-channel operations that can carry far at night but struggle during the day. The network manages them by providing a live audio feed, game notes, and pre-recorded promos. Affiliates handle their own marketing and local sponsorship sales, which is why the coverage map looks the way it does — it's shaped as much by economics as by antenna placement. I worked on a project a few years back where we had to reroute the Reds feed because one of the Kentucky affiliates lost their satellite uplink right before a home stand. The station was on a older Ku-band dish that started dropping packets during rain. We ended up switching them to an IP-based feed through a third-party distributor, which added about 80 milliseconds of latency. Nobody in the stands noticed, but it showed up on monitoring software and made the audio look worse than it actually was. The fix was just adjusting the buffer settings on their decoder and running a parallel satellite feed as backup. You don't fix that kind of thing by guessing.

The actual routing process starts with the home game production truck. They capture audio from multiple microphones around the ballpark — crowd mics, booth mic, isolated instrument feeds — and mix it down to a stereo program feed. That feed goes to a master control facility, usually managed by the flagship station. From there it's distributed through a satellite network provider. Most major sports networks use Bell TV or similar platforms for this. The feed hits each affiliate's receiver, and the station either plays it straight or feeds it through their own board if they're adding local commentary. The affiliate agreement is where most of the friction happens. Each station negotiates its own terms. Some want exclusive rights to Reds content in their market. Others just pick up the feed and run it. The network provides the audio, the affiliates provide the transmitters and the local audience. It's an old model but it still works because the cost of building something newer is higher than maintaining the existing one. Here's something most people don't think about: the audio quality varies wildly across the network. WLW itself broadcasts in a decent stereo feed, but a lot of the smaller affiliates are running mono through AM transmitters with very limited bandwidth. If you're listening on an economy car radio in northern Indiana during the day, you're getting maybe 5 kilohertz of audio bandwidth. Bass disappears. Crowd noise turns to mud. That's not a production problem. That's the physics of AM radio at 700 kilohertz. The network also streams games through the Reds' official app and website, which gives a completely different quality tier. Those streams use AAC encoding at around 128 kbps and route through CDNs. The problem there is geo-blocking. If you're outside the Reds' designated broadcast territory, the stream gets blacked out. MLB's national blackout policy applies, and the radio network has to respect it. This causes complaints every season from listeners who assume "radio network" means "anyone can listen anywhere." It doesn't. One thing beginners always get wrong is thinking the affiliate count matters more than the affiliate quality. Having 21 stations sounds impressive, but four of those stations cover maybe 15 percent of the actual listener base. The rest are fill-in territory. The real reach comes from WLW's 50,000-watt clear channel signal, which can be heard across much of the eastern United States at night. That's why the Reds have a national fanbase that tunes in without realizing they're picking up the flagship through skip propagation. The network's current structure has some real limitations. The affiliate model means the Reds have less control over production consistency. Some stations run the full game. Some only carry the first seven innings and then drop to a talk format. A few simulcast with television instead of running their own radio broadcast. There's no standardization beyond the audio feed itself. If you want a consistent experience from Cincinnati to Evansville to Louisville, you're better off using the team's digital platforms. The over-the-air network is built for reach, not uniformity. Another issue is funding. Radio network costs money — satellite time, production staff, transmitter maintenance, affiliate relations. When advertising revenue drops, that's where the network feels it first. I've seen smaller affiliates drop out between seasons because the sponsorship deal couldn't cover the transmission costs anymore. The Reds have been pretty good about keeping the core network intact, but turnover among the lower-tier affiliates is constant. New stations join, old ones leave, and the coverage map shifts every year without much public notice.
