Why Michigan Wolverines' Radio Crew Almost Changed This Season
Michigan Wolverines radio announcers are the voices who carry Michigan football, basketball, and hockey broadcasts to fans on the radio, and the current football booth is Doug Karsch on play-by-play with Jon Jansen on color commentary, while the program's flagship rights moved to 94.7 WCSX-FM beginning with the 2025 season. The phrase also usually refers to the broader broadcast team around them, including pregame, halftime, postgame, sideline, and studio voices that help shape how Wolverines games sound on air.
Current broadcast setup
The modern Wolverines radio network is centered on Michigan's new multi-year broadcast partnership announced in April 2025, which made 94.7 WCSX-FM the flagship station for football, men's basketball, and ice hockey. The university said the arrangement also keeps live game coverage available across a wider regional radio footprint, which matters for a fan base spread well beyond Ann Arbor and the Detroit metro area.
For football specifically, Doug Karsch and Jon Jansen remain the main announcers, with Karsch handling play-by-play and Jansen providing analyst work. That pairing replaced the long-running booth of Jim Brandstatter and Dan Dierdorf after both retired following the 2021 season, giving the broadcast a more contemporary tone while keeping strong Michigan ties in the booth.

What they are known for
The best radio announcers for a college brand like Michigan do more than describe the action; they translate atmosphere, momentum, and strategy for listeners who cannot see the field. Michigan's voices have historically been recognizable because they blend deep football knowledge with the cadence of a home-state broadcast, which is why the booth change drew attention from fans and media alike.
Jim Brandstatter's tenure is a major part of that history. According to his public bio, he served as Michigan football radio announcer from 1979 to 2021, a run that spanned multiple coaching eras and the modern expansion of college football media. Dan Dierdorf, another notable former voice, retired alongside him after the 2021 season, closing a long chapter in Wolverines broadcast history.
"We are also pleased to announce that Jon Jansen and Doug Karsch will remain as the voices of our football radio broadcasts," Michigan Sports Properties said in the 2025 partnership announcement.
Why the booth matters
The broadcast booth shapes how a game is remembered because radio listeners experience every drive, shot, and stoppage through the announcers' timing and vocabulary. At Michigan, the announcers also function as ambassadors for one of the nation's largest college sports brands, which means they are expected to be accurate, fast, and steady under pressure.
That pressure is especially high in football, where a single call can become part of team lore. Michigan's radio voice needs to handle big moments in real time, but also stay clear enough for listeners in cars, bars, tailgates, and kitchens, where the game may be heard without a screen.
Things they won't say
Despite the loud personality associated with college sports radio, there are still limits on what a game announcer will say live. They generally will not criticize specific players in a way that sounds like personal attacks, and they avoid speculation that could create confusion or fuel rumors during an ongoing game.
They also will not usually discuss private medical details, off-field discipline, recruiting gossip, or unresolved personnel issues in real time. In practical terms, that means a radio booth is built for description and analysis, not for leaked information, defamation risk, or emotionally loaded commentary that could embarrass the university or the network.
- They avoid personal insults toward players, coaches, or officials.
- They do not reveal confidential injury or locker-room information.
- They usually avoid unverified speculation about transfers, suspensions, or coaching changes.
- They keep sponsor-read obligations separate from on-air analysis.
- They stay within broadcast and university standards for language and professionalism.
Historical context
The history of Michigan football radio is a story of continuity, because the program has long treated its broadcast voices as extensions of the brand. Brandstatter's 1979-to-2021 run covered decades of changing media habits, from AM radio dominance to streaming-friendly distribution and the modern expectation of multi-platform coverage.
The 2025 flagship shift to WCSX-FM is also important because it reflects how college athletics now value stronger regional FM reach, clearer audio, and broader lifestyle-audience compatibility. In the Detroit market, Michigan fans can now hear football, men's basketball, and hockey on one prominent FM signal, which is a practical upgrade for a fan base that still cares deeply about radio access.
How the team is organized
A modern Wolverines broadcast is usually divided into distinct roles, and that structure matters because each segment serves a different listener need. Play-by-play gives the live action, color analysis explains tactics and context, sideline work adds updates and atmosphere, and pregame/postgame segments wrap the story before and after the contest.
- Play-by-play: Tracks every snap, pass, and possession.
- Color analysis: Explains strategy, matchups, and trends.
- Sideline reporting: Adds injury, weather, and momentum updates.
- Pregame and postgame hosting: Frames the story around kickoff and final whistle.
What fans should listen for
When fans tune in to the Michigan Wolverines on radio, the most useful signals are clarity, rhythm, and trust. A strong booth does not try to sound shocking; it sounds informed, quick, and consistent, especially when the game is chaotic or the crowd noise is overwhelming.
Doug Karsch's job is to keep the call moving, while Jon Jansen's role is to explain what the Wolverines are trying to do and why it works or fails. That combination gives listeners both the event and the interpretation, which is the core value of a radio broadcast.
Frequently asked questions
Why the search matters
People looking up Michigan radio announcers usually want either the names of the voices, the station carrying the games, or the history behind the broadcast team. The answer is that the current football booth is Doug Karsch and Jon Jansen, the flagship moved to 94.7 WCSX-FM in 2025, and the long-running Brandstatter-Dierdorf era ended in 2021.
That combination of old and new is what defines the modern Michigan radio identity: a historic program, a refreshed broadcast home, and announcers who are expected to deliver every game with precision, restraint, and a distinctly Michigan point of view.
