2025/02/21

John Kean, Dave Hershberger, and Tom King recently set out to take measurements of RF noise levels on various roadway types from open interstate highways to city streets, to determine how the noise would affect AM broadcast reception. These environments reflect the current habits of AM radio listening, which is primarily in vehicles. In addition to RF noise level, RF signal levels were measured for three AM stations operating on frequencies in the low, middle and high ends of the AM broadcast

Charlie Wooten is usually dealing with tornados, thunderstorms, and hurricanes. But last week brought a rare hazard to the Florida Panhandle - an ice and snow storm. With chunks of ice falling from hundreds of feet above, Charlie was keeping his stations on the air. Let’s find out what Charlie did to prepare for this snowstorm, and how his planning for other bad weather provided more assurance for continued operation for his 12 transmitters in the Florida Panhandle.Show Notes:The Freeze

TWiRT - This Week in Radio Tech - Podcast ·

2025/01/24

Today we're diving into a critical topic: the evolution from solo engineering efforts to collaborative support models in broadcasting. Just as a one-person band can only play so many instruments at once, a single engineer can't tackle every technical challenge alone. By banding together and working in groups outside traditional broadcast companies, we can support one another, foster career growth, and achieve a healthier work-life balance. Our guests Rob Bertrand and Shaun Dolan aim to do just

Necessity truly is the mother of invention. So, when Jim Gray and Alex Hartman needed to gain remote control of some late-model CD players, they developed “Babelfish.” The Babelfish Ecosystem is a solution for logic integration amongst systems that typically are unable to communicate with each other. Whether it's a 40 year old on-air light system that only speaks in relays or a new IP based system that only communicates virtually, the Babelfish Ecosystem allows unlike systems to

In late September, 2024, hurricane Helene hit parts of Florida and caused wind damage and severe flooding in Georgia, South Carolina, and especially Western North Carolina. Hurricane Milton hit Florida in October, 2025, causing even more damage there. In both storms, electricity was knocked out, cell phone service disrupted, and Internet was down for many. In these disasters, local and regional radio largely remained on-the-air, alerting listeners to the storms’ arrivals and keeping them

2024/11/15

Most broadcast engineers love a good project - especially when planning and resources overlap to enable a worthy outcome. But even solid “enablement” requires an engaged and knowledgeable engineer to guide the project’s moving parts, seeing the project through, and making sure the outcome fits the goal. That’s where Aaron Cox comes in. Aaron appreciates a good project - even a complex one - and he’s our guest, describing several compelling broadcast projects. From a

2024/10/25

Conditional Access systems for building security have always seemed like a “per building” or “per campus” proposition. But with today’s ubiquitous Internet access, and somewhat autonomous operation, conditional access systems can be deployed in remote locations. They can provide not only conditional access security, but also inform site owners of who is opening doors and gates, and exactly when they’re doing it. It’s convenience for those requiring access,
