Even for an experienced duo like the father-and-son combination of Joe and Jeff Geerling, they were amazed at all that goes into keeping St. Louis Blues games ready for fans watching both at home and in the arena.

Joe is a broadcast engineer with more than five decades of experience in the St. Louis radio market and is currently the director of engineering at Covenant Network.

Jeff is an accomplished software architect and developer who started to tag along with his dad on radio exploits at an early age.

Joe and Jeff have produced many YouTube sensations, typically related to radio and engineering. We’ve detailed them in the past.

They used an opportunity in October to explore the Enterprise Center, the home of St. Louis’ NHL team, to detail what goes into the Blues’ video broadcast productions.

At the bottom of this story you can watch the entire video. First, some background.

At first, the Geerlings thought the visit was going to be an equipment “geek out” inside an SMPTE ST 2110 IP-based mobile unit, the nerve center for TV broadcasts at Blues games, in the flavor of Geerling Engineering videos in the past. The truck is operated by Mobile TV Group and according to Jeff, it drives to multiple broadcast facilities throughout a given week.

And while there’s plenty of AoIP, Dante, cameras and other modern equipment featured in their latest video, in a refreshing twist for 2026, it’s more about another aspect.

“It really shows the dedication of the team in broadcasting,” Joe Geerling told us.

The "third team," as Jeff put it.

Inside the Truck
The video goes inside each of the three such teams at Blues games: One production crew for the fans in the building, one for FanDuel Sports Network Midwest, which broadcasts Blues’ games, and one for whomever that night’s away team happens to be.

The home team truck’s broadcast engineer, Chris Bailey from the Mobile TV Group, took the Geerlings inside the truck that is used at Blues’ games.

“This team is amazing with how they put together the use of all the technology in real-time,” Joe reported from inside the truck.

Timing, is of course, critical. Jeff noticed that GPS is not used for time sync inside the Mobile TV Group truck.

That’s because of poor satellite reception. So instead, the truck’s Evertz Master Clocks are frequently synced manually to an atomic time source — such as the iOS Atomic Clock app — to ensure the truck’s internal pulse matches the rest of the world.

There’s other “old tech” at work in the video too. Jeff anticipated fiber cables to be everywhere. Instead, analog copper is the choice.

“If you have one or two copper wires go dead, you can still have a show,” he explained.

Jeff remarked that inside the truck, the atmosphere was almost solemn. Everyone is quiet, but constantly aware of everything going on around them. He captured some of that back-and-forth in the video.

Hockey is Different
They also showed off what goes inside the Enterprise Center, where there is a separate production crew delivering visuals to the fans inside the arena.

“Hockey is the best and most challenging,” longtime cameraman Mike Munaco told Jeff. “It is the most fun to shoot because you have to stay ahead of what the announcers are talking about.”

Chris Kerber, the play-by-play announcer for Blues’ home TV broadcasts on FanDuel Sports Network Midwest, talked about the visual and auditory back-and-forth with the production truck.

“The chain doesn’t work unless every link is strong,” Kerber said about the FanDuel production truck. “If the real good synergies aren’t there, then the fans don’t get a good experience.”

There is a great deal of gear highlighted in the video, but really, it’s about the human touch.

“It’s a huge group of great talent, and none of it is wasted,” Jeff said.

MONTREAL—The Scotttrade Center in St. Louis, home to the St. Louis Blues, went through some offseason adjustments leading up to the 2016-2017 NHL season, installing video equipment from Grass Valley into its video control room.

Among the new gear that was added to the arena’s system was the 3M/E Karrera K-Frame S-series production switcher; three LDX 86 WorldCam cameras for HD/3G acquisition; an LDX 86 XtremeSpeed camera for 6X HD and 1X/3X 3G acquisition; an LDX C80 compact WorldCam for remote applications; XCU Universe XF base stations; six Densité 3 Frames for housing audio and video signal processing modules; eight Kaleido-Modular-X multiviewers; two K2 Dyno Replay systems with ShareFlex capability; an NVision 8500 Hybrid Series router with 144x144 matrix; and an NV9000 controller.

The St. Louis Blues are also anticipating upgrading its video and LED boards, for which it expects to utilize the Karrera K-Frame switcher to sync their video boards, ice projection systems, lighting systems and more.

According to Grass Valley, the installation process took three months.
