TWiRT 809 - Public Radio Studios in Knoxville with Tim Berry

Our guest on This Week in Radio Tech episode 809 is Tim Berry, Chief Engineer at WUOT-FM, the public radio station at the University of Tennessee in Knoxville. WUOT combines NPR news with classical and jazz music, much of it still played live from CDs and occasionally from the station’s enormous collection of LPs. 

Tim gives us a tour of the control room, performance area, technical center, and an extraordinary music library that also includes thousands of historic 78 RPM records. We’ll see one of Tennessee’s earliest Audio over IP installations, built around Axia Livewire technology and operating for about 15 years. 

Tim also maintains more than 20 analog and digital amateur radio repeater sites throughout East Tennessee. Join us for a fascinating look at preserving broadcasting’s rich history while planning the technical upgrades that will carry WUOT into the future.

TWiRT 808 - When the Chief Engineer Becomes CEO with Brett Gibson

Brett still has one foot firmly planted in the engineering world, even as he steps into the broader leadership responsibilities of running a radio ministry. That gives him a valuable perspective: he understands transmitters, studios, IP links, automation, remote sites, monitoring, redundancy, and after-hours recovery — but now he also has to think about budgets, staff, listeners, board expectations, and the mission of the network.

On this episode, Brett joins Kirk Harnack and co-host Chris Tarr, for a practical conversation about what it takes to build and maintain a reliable broadcast operation today. Brett shares how Voice of the Master’s technical plant has evolved over the years, what systems and standards have made the biggest difference, and how deeply IT has become integrated into modern radio engineering.

You’ll hear discussion about working at transmitter sites, improving reliability across multiple facilities, using technology wisely, securing remote access, documenting systems, and preparing for the inevitable late-night trouble call. Brett also talks about the transition from engineering leadership into the CEO role, and what broadcast engineers should learn if they want to grow beyond the rack room.

It’s a conversation about engineering, leadership, stewardship, and keeping radio stations operating smoothly and reliably — all on This Week in Radio Tech.

TWiRT 807 - Today's FM Radio Technology with William Harrison

William got his start in public radio in the 1990s at WAMU-FM, where computer work quickly expanded into audio and electronics. Since then, he’s worked with PBS, NPR, The Metropolitan Washington Ear, and a number of FM and TV broadcasters. He also chairs SBE Chapter 37 in D.C., serves on the Virginia SECC, sits on the board of the Association of Public Radio Engineers, and occasionally writes for Radio World.

In this episode, we talk about real-world FM engineering, including Capital Concerts fireworks show coordination, HD Radio timing and “ballgame” mode, receiver metadata behavior, liquid-cooled transmitters, HLS streaming for broadcast STL use, and dynamic range control in xHE-AAC.

Join us for a practical, wide-ranging conversation about broadcast engineering, public radio operations, and the listener experience on This Week in Radio Tech.

TWiRT 806 - Engineer of the Year, Terry Harper

This Week in Radio Tech is on location for episode 806 at the Auburn Marriott Opelika Resort & Spa in Opelika, Alabama, where the Alabama Broadcasters Association is celebrating its 80th anniversary with one of several regional receptions around the state.

This episode brings together three conversations that say a lot about where broadcasting has been, where it is now, and where it may be headed. First, we visit with Terry Harper, the ABA’s 2026 Engineer of the Year. Terry’s broadcast career reaches back nearly six decades, beginning in 1967 at WABT in Tuskegee, continuing through years of engineering work at Auburn University, and then into decades of contract engineering service for Alabama broadcasters.

We also talk with Lee Perryman, owner of RadioAlabama, about the practical use of artificial intelligence in local radio. Lee is not just speculating about AI; he is putting generative AI and curated synthetic voice tools to work in real station operations, including story writing, announcements, commercial production, and other content workflows — while keeping a broadcaster’s judgment in the process.

And we spend a few minutes with Sharon Tinsley, president of the Alabama Broadcasters Association, about the significance of honoring Terry Harper, the value of broadcast engineering to local stations, and the ABA’s decision to take its 80th anniversary celebration on the road to broadcasters across Alabama.

It’s a field trip episode, a celebration episode, and a forward-looking conversation all in one. Join us from Opelika, Alabama, for episode 806 of This Week in Radio Tech.

TWiRT 805 - FCC Mandatory Cybersecurity for Broadcasters

Cybersecurity is no longer just an IT department concern — it is becoming a broadcast engineering issue, and possibly soon, a regulatory one as well.

On episode 805 of This Week in Radio Tech, we’re joined by three experienced broadcast engineers from Georgia and South Carolina: John George, Charles Kinney, and Earl Welsh. We’re talking just ahead of the Georgia-Lina Broadcast Engineering Conference in Augusta, Georgia, and our topic is both timely and practical: the FCC’s proposed cybersecurity rules for broadcasters, especially as they relate to EAS equipment, studio-transmitter links, remote access, and other internet-facing systems that can affect what goes on the air.

We’ll discuss what the FCC appears to be concerned about, why default passwords and exposed web interfaces are no longer just “bad practice,” and what station engineers can do now to improve security before a rulemaking turns into a compliance deadline. This is not a theoretical conversation — it is about real broadcast facilities, real equipment, and real operational risks.

Join us for episode 805 of This Week in Radio Tech as we look at cybersecurity through the eyes of working broadcast engineers.
