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 band. These measurements provide a better understanding of how AM radio reception is affected by RF signal strength and noise in a range of roadway environments from rural to dense urban environments. On this episode of TWiRT, John Kean and Dave Hershberger join us to describe the testing methodology and the results and conclusions we can infer from them.

Radio automation systems seem daunting at first glance. Those new to their programming and operation are often surprised by the number of pre-requisites and source material needed to put a radio format together, especially when the automation system is thought to do these things for you. Not to worry, Chris Tarr is here to clear up confusion and doubt, and help broadcasters consider some of the key aspects of implementing a radio automation playout system.

When a classic audio mixing console needs to be refurbished and brought back to life in Tennessee, everyone knows to call on Jim Gilmore. One reason is that he may have installed it in the first place! Jim might be a true Renaissance Radio Engineer! From on-air work, to traveling the world for Harris Broadcast, to engineering at The Nashville Network to CMT, to even teaching audio classes at Belmont University, Jim has certainly “been there and done that”. Join us as Jim shows us a totally refurbished audio console, originally built by WSM engineers, and used for a decade at The Grand Ole Opry at the Ryman Auditorium. Plus, meet Linda Chambers, CEO and Co-Founder of the Musicians Hall of Fame and Museum, as she takes us through Brian Ahern’s 42-food Encatron Mobile Recording Studio!

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.

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 that at Inrush Broadcast Services,, a 14-person broadcast technology service provider

What kind of “radio station” is on-the-air only twice per hour? How about CBS Radio News? With the precision of a watchmaker, the CBS Radio News network delivers news updates to hundreds of radio stations and millions of listeners. Mitch Glider is the Supervising Engineer at their headquarters on West 57th Street in New York City. Through the challenges of at-home news anchors (through the pandemic) and changes in technology, Mitch and just a few colleagues keep the audio and metadata correctly routed. In this episode, we’re learning about past, present, and future network radio operations. Mitch encourages engineers to “Respect the past, and embrace the future.”

If you’re building a new radio studio, or rebuilding one, Chris Tarr is here to help. This is your opportunity to get The Ninjaneer’s expert advice without laying out thousands of dollars in consulting fees. In this episode, we’re looking at various technologies to link your radio studio with your transmitter site. There are more choices now than ever! And we’re looking at today’s radio studios; how are they different from those of the past? We think studios can be a lot simpler than they used to be, mostly thanks to Audio over IP technology.

If you’re building a new FM radio station, or rebuilding one, Chris Tarr is here to help. This is your opportunity to get The Ninjaneer’s expert advice without laying out thousands of dollars in consulting fees. This episode focuses on what to do when you get your FCC Construction Permit. Chris gives hard-earned advice on towers, antennas, transmission line, transmitter selection, and more.

What’s ahead in 2025 for radio programming? For radio talent? For radio programming executives? Where does Artificial Intelligence fit in? What audience is key to attract to radio and how can radio programmers make headway on that? How will new “PPM Wearables” affect station ratings? And how important are streaming and on-demand programs to radio’s future success? We got answers and opinions on all these questions from John Shomby at Country’s Radio Coach. John’s been a consultant, programmer, and coach focusing on Talk Radio and Country Radio formats, and he’s our guest this week filling us in on the key topics and strategies for radio’s future success.

Jeff McGinley is the kind of engineer who pays attention to the important things. He’s focused on the technologies that bring value to the on-air talent and to the listeners, all the while satisfying the shareholders drive for return on investment. Jeff’s advice is based on real-world experience, so you know there’s value there, too. On this episode we’re discussing the end of official support for Windows 10, and moving to Windows 11. Plus, Jeff and Chris both relate the importance of good metadata for listeners via RDS and PAD (for HD Radio). And we discuss the significant benefits of 11 GHz IP Radio links.
