TWiRT 778 opens with a broadcaster whose reach spans far beyond the cotton fields and high plains of West Texas. Tony St. James, owner of KFLP AM-FM in Floydada, has built a multi-platform media operation that punches far above its market size. Alongside running his stations, Tony operates two prolific content networks: the West Texas Friday Night Scoreboard and the All Ag Network. His voice is also instantly recognizable to rural audiences nationwide through his frequent appearances on RFD-TV and SiriusXM’s Rural Radio channel. Tony joins Kirk Harnack to talk shop about the technical, workflow, and operational strategies that allow a...

AAT—American Amplifier Technologies—might not have been on your radar a few years ago, but they’re making some serious noise in the broadcast engineering world. With their TXN line of FM and Digital TV transmitters, plus their recent acquisitions of Shively, Kathrein, and SCALA, AAT is quickly becoming a true one-stop shop for RF and broadcast hardware. Today we’re joined by AAT’s Chief Technical Officer, Matt Rigdon. He’s here to show us emPower, a brand-new monitoring and control system that was designed from day one with broadcast engineers—and our mobile lifestyles—in mind. Under the hood it’s po...

Episode 776 of This Week in Radio Tech brings a heartfelt and energetic conversation titled “Thankfulness with K-LOVE Engineers.” Joining Kirk are four outstanding engineers from K-LOVE and Air1—Chris Tarr, Jack Roland, Tommy Presite, and Bill Jackson—who share real experiences where gratitude has shaped their work and even their success. This episode blends lively banter with meaningful reflections on how being thankful affects everything from troubleshooting transmitters to strengthening family life. Together we explore how thankfulness transforms the one who practices it, even in the secular workplace where its power is often overlooked. It’s an uplifting and authentic discussion...

In this episode, Kirk welcomes Keith Pelletier, President of Dielectric, to explore the newest advances in FM transmitting antenna design. Keith explains how Dielectric engineers are now combining custom bay spacing, including innovative mixes of full-wave and half-wave spacing within the same antenna aperture, to deliver precise coverage patterns with dramatically improved efficiency. These hybrid designs can achieve the same or better performance while using about one-third fewer parts, reducing weight, wind load, cost, and long-term maintenance challenges. We also dive into how modern modeling tools, materials, and manufacturing techniques are pushing FM antenna technology further than ever before. If...

This week on This Week in Radio Tech, we’re joined by Adam Robinson, Director of Sales & Marketing at MaxxKonnect and Triple Helix Technologies. Transmitter sites have evolved far beyond just RF gear — they’re now fully IP-centric ecosystems where slow, hidden failures often do the most damage. Adam and Kirk discuss how smart monitoring, redundancy, and unified visibility are redefining how engineers manage their sites remotely. From HVAC degradation to IP jitter and network security, we explore why data over time is the key to preventing downtime. Tune in and learn how the next generation of site management — predictive, cloud-in...

This week on This Week in Radio Tech, host Kirk Harnack welcomes broadcast engineer and on-air talent Steven Zagony, a man who finds joy in bringing classic broadcast gear back to life. Steven restores beloved analog equipment from the golden era of radio—think Studer, MCI, Auditronics, ITC/3M, PR&E, Orban, Texar, and more. From cleaning and recapping to precision alignment, he shares the process and satisfaction of hearing vintage gear sing again. We also dive into his work on KFRC’s legendary remote vehicle, “The Sturgeon,” where Steven rebuilt its PR&E console and revived its ITC cart machines...

Before Angry Audio, Michael “Catfish” Dosch helped redefine how audio moves through radio stations. In this episode, Catfish joins Kirk to revisit the early 2000s when he, Steve Church, and a small development team in Riga, Latvia, built the world’s first practical Audio over IP system — Livewire. From his PR&E console-design roots to creating the Telos SmartSurface and the first Livewire mixing engine, Catfish shares behind-the-scenes stories, engineering breakthroughs, and lessons that changed broadcast infrastructure forever. It’s a fascinating trip back to the dawn of AoIP — where analog met Ethernet and radio changed for good.
