TWiRT 825 - Infrared Thermography with Dan Gunter

We’re used to pulling out our phones, snapping a picture, and letting the camera figure out the settings. So how hard could it be to point an infrared camera at a breaker panel and see what’s running hot? As I learned on this episode, getting the picture is the easy part. Knowing what temperature it actually represents takes some expertise.

On episode 825 of This Week in Radio Tech, we’re joined by Dan Gunter, an Alabama contract broadcast engineer who takes care of several radio stations and is also a certified thermographer. Dan explains how air temperature, humidity, and the surface you’re measuring can all affect a reading. That last part involves emissivity, which is how readily a surface gives off infrared energy. A shiny metal surface, for example, can reflect heat from something nearby and make the image easy to misread.

Dan walks us through which readings you can trust, which ones need an adjustment, and what to expect from different materials around a broadcast plant. Join us for TWiRT 825 and hear how Dan uses infrared thermography to spot trouble before it takes a station off the air.

Show Notes:
Using a thermal camera with your phone.  FLIR’s guide walks through its iPhone and Android app, including how to take a thermal image, use spot temperature readings, and adjust emissivity. 

Why shiny metal can fool a thermal camera.  This illustrated explainer shows how surfaces at the same temperature can look different in a thermal image, and how a shiny surface can reflect heat from somewhere else in the room. 

How to get certified in infrared thermography. The Infrared Training Center outlines its Level I courses, what the training and exam cover, and an option focused on electrical inspections.

TWiRT 824 - Silicon Carbide: AM’s New Horsepower

What happens when transistor technology proven in electric vehicles finds a new home in an AM transmitter? You get a fresh approach to making RF power—with less wasted energy, less heat, and a remarkably smaller footprint.

On this episode of This Week in Radio Tech, Rich Redmond, President and CEO of Broadcast Electronics, and Tim Hardy, Senior RF Engineer, join us to explore the silicon carbide MOSFET technology behind BE’s new AMX transmitter series.

But the conversation goes well beyond the transistors. Rich shares what he saw in Broadcast Electronics that inspired him to become an owner. And we explore the partnership behind a dependable product: What does an engineer need from his CEO to do his best work—and what does the CEO need from the engineer to turn a promising design into equipment broadcasters can trust?

We also look at the possibilities for putting more of the transmitter site inside the transmitter itself: audio processing, HLS stream reception, a built-in receiver with streaming for remote listening, and potentially software-based EAS as FCC rules permit. Rich discusses how this approach could extend across AM and forthcoming FM products, reducing the space, equipment, and heat load needed to keep a station on the air.

Join us for a conversation about better transmitters, thoughtful engineering, and the people helping shape the next chapter of Broadcast Electronics—on This Week in Radio Tech!

TWiRT 823 - Virtual Voice Talent from a Radio Champion

How do you give a virtual radio DJ the personality, emotion, and local knowledge that make listeners feel connected? On episode 823 of This Week in Radio Tech, Jeff MacIntyre—also known as RadioDJ Dude and founder of RoboDJ—joins us to explain how virtual voice tracking works. We explore how voices are shaped and adjusted to sound natural, with the expression and organic feel you’d expect from on-air talent. Jeff also explains how scripting brings together community information, songs just played, and music coming up, all tailored to the air shift, time of day, and program director’s instructions. We hear examples actually airing on radio stations, plus insights from returning guest Lee Perryman, who makes extensive use of RoboDJ’s virtual talent across his dozen stations in east central Alabama. Join us for a listen to the technology—and the programming decisions—behind these virtual voices!

TWiRT 822 - Live from OAB EXCHANGE

This Week in Radio Tech hits the road for episode 822, recorded live at the Ohio Association of Broadcasters’ OAB Exchange in Newark, Ohio! The new location outside Columbus provided a welcoming setting, with plenty of laughter, good conversation, and broadcasters comparing notes between sessions. Engineers, station managers, and sales professionals all had opportunities to learn something useful and catch up with their colleagues. Engineering sessions covered everything from HLS studio-to-transmitter links and cybersecurity to audio processing, antenna troubleshooting, and staying safe at transmitter sites.

OAB President Chad Budreau joins me, along with MaxxKonnect’s Matt Levin and Adam Robinson. We’re also joined by Geary Morrill, Regional Director of Engineering at Connoisseur Media, and Chris Winters, Director of Engineering at Spirit Communications. The camaraderie that made this gathering so enjoyable carries right into our podcast conversation. Pull up a chair and join us for TWiRT 822—a little broadcast engineering, a few friends, and a good time in Ohio!

TWiRT 821 - What's the State of My Empire?

How many things can you monitor at your broadcast facilities? And how many different systems do you have to check to know whether everything's working properly? Today's technology makes it possible to bring an extraordinary amount of information together into one convenient dashboard, giving broadcast engineers and station owners a network operations center of their own. From transmitter health and studio audio to computers, streaming signals, EAS equipment, and even FCC filings and FAA notices, there's more we can keep tabs on than ever before. Better yet, much of this information can be gathered from equipment you already own, using existing network protocols and automated reporting. 

On This Week in Radio Tech, we're exploring how cloud-based monitoring, intelligent alerting, and centralized site management are changing the way we maintain broadcast operations. Mike Hutchins, Director of Technical Services, and Josh Bohn, President and CEO of MaxxKonnect, join us to explain what's possible today and where this technology is headed. It's TWiRT episode 821, "What's the State of My Empire?"
