TWiRT Ep. 548 - Combining FM Stations with Rob Bertrand and Andy Gunn

Too many FM antennas on one tower? They’re (maybe) creating intermod products? No room or structure for more tenants? It may be past time to consolidate all the FM signals onto a master FM antenna. WAMU-FM and WTOP-FM in Washington, DC, did exactly this - and worked with other FM tenants on the same tower to create such a combined, master FM antenna system. Rob Bertrand, CTO, and Andy Gunn, DoE, tell the story and give us a tour of the combiner room at American University.


TWiRT Ep. 547 - Docker for Broadcasters with Cam Eicher

Heads-up, broadcast engineers! Docker is coming your way. What's Docker? It's a brand name that's part of "containerized software" - and broadcast equipment is already moving there. Your audio consoles, talkshow system, and IP intercom can all run on PC or servers - on-site or in a data center. This is happening now! Cam Eicher with Telos Alliance gives a great tutorial on Docker containerized software and more on this episode of TWIRT.


TWiRT Ep. 546 - Nineteen Mix-Minus Feeds with Rob Ashard

Cris Alexander, DoE at Crawford Broadcasting, deals with these problems and more, and depends on a team of local engineers as well. We get to spend an hour with Cris...


TWiRT Ep. 544 - Busta 'Crete with John Bisset

Bustin’ concrete, CIDR notation, Rat Magic, unlimited (almost) photo storage, more mouse eviction tactics, and the best site maintenance practices. Whew! It’s all covered and uncovered on this TWiRT episode with the beloved John Bisset, author of “Workbench”.


TWiRT Ep. 543 - EAS, One Year into the Pandemic - with Adrienne Abbott

EAS - The Emergency Alert System: Is it sometimes a pain for broadcasters? Or is it a life-saving emergency messaging system? Adrienne Abbott is Chair of the Nevada EAS. She brings a balanced and reasonable perspective to EAS operations and functionality. Plus, she’s helping to enhance the localism of EAS alerts in Clark County, Nevada, where Las Vegas and suburbs sprawl across the high desert.


TWiRT Ep. 542 - Engineering Adds Revenue via RDS with Joe Marshall

The FM Radio Data System has been around for 45 years, but internationally finalized in 2000. Despite being a worldwide standard, radio manufacturers and broadcasters have implemented the standard in different ways, resulting in rather inconsistent information displays for consumers. One leading company fixing this problem is Quu. Joe Marshall is the Technical Success Manager for Quu, and focused on helping FM broadcasters get consistent and compelling data and graphical displays on every FM...


TWiRT Ep. 541 - Complexity Has Disappeared with Dan McQuillin

Dan McQuillin is known for making complex broadcast operations much simpler, often by “disappearing the complexity”. We’re looking at the Digital/Bionic Table and the overarching themes in the way technology is deployed that Table leverages... Software, Browser based interfaces, BYOD and Virtualisation, and the impact that leaning in to these changes can have on the way spaces are designed and content is created and consumed.


TWiRT Ep. 540 - Advanced Engineering at NAB with David Layer

Most broadcast engineers know of David Layer. He’s the VP for Advanced Engineering at the NAB. We know David because he has frequently given presentations about radio technology at broadcast trade shows. The hope of a reduction or end to the COVID pandemic has broadcasters enthused about meeting again in Las Vegas - this time in October, 2021 - for an NAB Conference and Expo, including the NAB Radio Show. David Layer joins us to discuss the rebuilding of the radio lab equipment and ongoing...


TWiRT Ep. 539 - Broadcast Orchestration with Dan Bays

When changing audio routing in a broadcast facility, we often need to change other routes as well. Control signals, metadata, monitoring points, and more. Dan Bays began designing routers for recording studios, connecting different brands of equipment on the fly. Now he develops systems that route Audio over IP and associated GPIO and other control data. And, sophisticated salvos and monitoring are combined with Logic Flows to create reliable, automated systems with redundancy, all to keep...


TWiRT Ep. 538 - Radio April Fools!

Of all the professions, those involved with radio broadcasting may rank highest in percentage of “jokesters”. We certainly have a 100% jokester guest panel on this episode of TWiRT! From engineers, to station managers, to on-air talent (and most have done 2 or 3 of these 3 things) our guests each have a very high “JQ” - Jokester Quotient. Enjoy with me these stories of April Fools jokes and pranks.


TWiRT Ep. 537 - Integrating Virtual Solutions in Broadcast with Jake Alderman

Jake Alderman is Program Director for Virtual Solutions at Telos Alliance. Sound intriguing? I think so! We see broadcast infrastructure moving more and more into a virtualized space - either on-premises or perhaps in the cloud, and Jake is just the guy to clarify some concepts about virtualization. From Virtual Machines (VMs) to Software Containers to hypervisors, Jake and his colleagues are pushing the envelope on broadcast operations.


TWiRT Ep. 536 - The Joy of Restoration with Jordan Tuck

Maybe you've seen Jordan Tuck's handiwork on Facebook; he refurbishes the radio gear we loved from the 70s, 80s, and 90s. Most of this cherished audio gear is older than he is! How'd he get so good at bringing consoles, tape decks, audio processors, etc. back to life? Jordan credits Mike Patton and others for showing him the way to broadcast equipment resuscitation, and he’s on this episode of TWiRT to tell us about it.


TWiRT Ep. 535 - Into the Fire with Andy Low

Andy Low began his broadcasting career with IT experience. His only exposure to audio or RF engineering had been through his father’s amateur radio equipment. But when the opportunity arose for Andy to assume an overall engineering position, he dove right in, learning what he needed to keep his stations on-the-air and making improvements. Andy’s experience with taking over in an “engineering vacuum” taught him the value of documenting everything, and he shares what he learned with us.


TWiRT Ep. 534 - Behind the Scenes on World Radio Day at WRHU-FM

WRHU at Hofstra University on Long Island has been chosen by the Academy of Radio Arts and Sciences of America to receive the 2021 World Radio Day Award. Andy Gladding, Chief Engineer at WRHU-FM, has led a cadre of Hofstra University students in planning, coordinating, and executing an impressive day-long broadcast for World Radio Day. So, impressive they even received a UNESCO award!


TWiRT Ep. 533 - Bold Radio Predictions for 2021 with George Zahn

There’s no way to know if 2021 will be less tumultuous than 2020, but last year was a turning point for many, if not most broadcasters. George Zahn, a Cincinnati-area broadcaster and audio enthusiast for over 40 years, notes a “dumbing down” of audio quality in broadcast, while some broadcast competitors are getting better. He joins us with solid advice and a warning or two about keeping great audio in broadcasting.


TWiRT Ep. 532 - Undo & Process with Jim Kuzman

When you meet someone who is positively expert at something, you want to ask questions, pick their brain, learn what they know. Jim Kuzman literally wrote the manual for the infamous Omnia 9 audio processor. He knows audio processing inside and out, and especially the processing functions found in the Omnia 9. What does “Undo” do? How should I use a multiband spatial enhancer? How many multibands of processing should I choose? And why are you clipping my bass notes separately? Jim reveals...
