Tom Morris always provides a fresh perspective on broadcast engineering. He’s fascinated by well-designed systems, yet finds the humor in poorly-designed ones. Tom finds nostalgia in equipment and broadcast products that most of us have forgotten. And his unconventional outlook often results in insights and solutions to complex problems. He’s the guy you want handy to solve long-standing issues when no one else has taken the time to investigate the root causes. Chris Tarr and Kirk Harnack welcome Tom Morris on this episode of TWiRT, and Chris also offers up a vexing set of symptoms at an FM station that took several days to fully repair.

The ABA Engineering Academy is offering the first round of broadcast engineering classes for 2024. The radio engineering class is scheduled for February 26th – March 1st. Larry Wilkins and Frank Giardina are the two main teachers and both join us on this episode of TWiRT! Larry and Frank give us sneak previews of some of the technical teaching topics and demonstrations to add meaning and context. Engineers - new and experienced alike - attend this Engineering Academy in Birmingham, Alabama. It’s especially useful to IT technicians getting into the world of audio and radio broadcasting.

Can a team of engineers resolve thousands of engineering trouble tickets each month, and do it efficiently and keep with good engineering practice? iHeartMedia is doing it and Mike Sprysenski is leading that team. From an office in Orlando, Mike Spry and a team of radio engineers and IT professionals resolve engineering issues at nearly 900 radio stations, keeping those stations on-the-air. Many issues are even handled preemptively, before they affect what the public is hearing over the air or online. Chris Tarr and Kirk Harnack discuss this approach with Mike on this episode of TWiRT.

The benefits of thoughtful and careful broadcast engineering cannot be overstated. Indeed, Jim Offerdahl, thought carefully about our offer to be on TWiRT for over 10 years! And, with some encouragement from Angry Audio’s Mike Dosch, we’re delighted that Jim is finally sitting in the TWiRT Guest Chair! We’re talking with Jim about his particular style of serving radio stations effectively and reliably. He’s sharing some tips and favorite equipment for monitoring and troubleshooting today’s transmission systems, plus letting us in on his part-time mayoral career in Fosston, Minnesota. Stay tuned until the end of the show when Jim is making an announcement about expanding Radio Gearheads!

What use is a low-wattage, AM radio station in a town of 2,000 residents? Indeed, the whole county population is just over 12,200. Is AM radio viable there? With 500 watts daytime and 18 watts at night what can a new owner do to revive such a station? Beth Mann, President/CEO of Edge Media Group, wanted to bring WEKT back to a rightful stature in this small, Western Kentucky town. Beth grew up in Elkton, across from the original WEKT studio and transmitter. Now she, along with her “digital- and future-oriented” staff. On this episode of TWiRT, she along with Josh Claussen and Bill Booth describe the technical operation, but more importantly the community involvement that’s driving Elkton’s embrace of WEKT, resulting in advertising and renewed revenue.

Rolf Taylor describes himself as a Lover of Audio, Tinkerer, Broadcast Engineer, Support Engineer and Product Manager, Telco Guru, and Researcher and Writer. As Rolf’s longtime friend, Kirk Harnack can attest to each of those appellations. Rolf joins us on this “Festivus” episode of TWiRT, though we spend most of our time on making product usage and support better, and just a few minutes on the “airing of grievances”.

As Chris Tarr points out, Paul B. Walker, Jr. is probably the most enthusiastic supporter of local radio service and programming. Paul is the Program Director at KSKO-FM in McGrath, Alaska, but he wears almost every hat required for running a full-service FM Public Radio station. Many TWiRT fans know of Paul through the Facebook group he started, “I Take Pictures of Transmitter Sites.” Chris Tarr and Kirk Harnack talk with Paul about the challenges of broadcasting in rural Alaska, including antenna icing, Internet service, STL connections to outlying villages’ FM transmitters, and even the occasional “moose fade”.

Any time spent with Charlie Wooten is time well spent! Engineering with iHeartMedia in the Florida Panhandle, Charlie keeps his Facebook friends apprised of bigger projects and occasional off-air emergencies. We also know that he loves “roughing it” at a 13,000 acre deer camp with longtime friends and fellow hunters. From a vexing audio crosstalk problem, to multiple station monitoring, to mentally resetting around a campfire, Charlie shares his thoughts on a great work-life balance.

Once each year we discuss air conditioning and airflow at transmitter sites - and we do so in preparation for hot summer weather. But what about temperature control and monitoring during the cold winter months? What issues arise when it’s cold outside but the transmitter is still making plenty of heat? There are many variations in scenarios, but Joe Fleming advises that monitoring the temperature at key locations is important to keeping tabs on your HVAC system and your transmitter’s health.

Have you ever been to Saskatoon, Saskatchewan, Canada? No? Not many have, even though it’s a thriving city with excellent radio stations and a lively downtown social, shopping, and dining scene. Saskatoon is also the home of Pippin Technical Service, a leading broadcast equipment dealer and project services firm for all of Canada. Pippin Technical, now “PTS”, is an early adopter of IT and broadcast technologies, including Audio over IP via Livewire and AES67. PTS boasts highly capable on-staff engineers, technicians, and programming developers. In this TWiRT episode we get a tour of this premier equipment and services provider, plus we talk with Tyler Everitt, PTS’s President, as well as Evan Semenoff, developer of the new PTS Aurora GPIO interface. We also take a quick trip - a live shot - out to a new studio under construction at Pattison Media in Kelowna, BC, Canada.

It’s only natural that we pause and consider the things - and people - we’re thankful for during the Thanksgiving Day holiday. Wow! What a list! It turns out we’re thankful for many more things than we can talk about in a 1-hour podcast! This week’s show features a slate of awesome broadcast engineers who remind the rest of us that we *do* have a lot to be thankful for. Enjoy this episode of TWiRT, and we know you’ll think of a few more things yourself!

Max Pandini is known throughout Southern Europe for his audio processing acumen, radio brand consulting, and compelling audio programming. Host, Kirk Harnack, actually didn’t realize it until today, but Max is now a colleague, working at Telos Alliance! Max maintains his consultancy for some of the tops radio brands like Radio Kiss Kiss (Italy), Klassik Radio (Germany), and DIXI Media (Moldova). We caught up with Max on a consulting trip in Verona, Italy from where he’s sharing his passion for compelling audio processing, visual radio and branding, and takes us inside a couple of beautiful broadcast facilities.

It’s said that sometimes it’s the plumber who has the worst home plumbing in town; ditto for the electrician with “temporary” fixes and home wiring done hastily, and in an un-workmanlike manner. Both professionals may not do it right the first time, knowing they can do it right any time. Which never comes. We broadcast engineers can fall into the same trap. We know where the twisted wires are that are holding the transmitter on-the-air, and we’re careful not to bump them as we do other work. Or we have an overflowing trash can at the transmitter site, which subconsciously deters us from cleaning up new trash as there’s nowhere to put it. Or we know just how to wiggle a power supply connector, or a tower light monitor, or other “percussive maintenance” tricks that no one else knows about. Radio’s most beloved conference speaker, Jeff Welton, and his colleague, Jeff Wilson, join us from Nova Scotia, Canada, with a full hour of smart ideas, clever hacks, and common sense about making your engineering life easier, and doing a better job of it.

Every time I check in with Josh Bohn, founder of MaxxKonnect Group, he’s busy on an engineering project, or on his way to or from a project. And he’s not alone. Seems that most broadcast engineers are absolutely slammed these days with upgrade projects, regular maintenance, and the usual off-air emergencies. Today Josh is in Indianapolis meeting with several other radio engineers, including Matt Levin. Wondering what kind of work is keeping engineers busy this year, I asked Josh to join us - and he did, along with three other engineers. Let’s see what’s keeping engineers so busy, and how are thoughtful engineers advising station owners to invest in equipment upgrades to avoid unscheduled off-air time.

When Hofstra University’s School of Communication hosted an SBE Ennes Workshop, coordinator, Andy Gladding, added an extra event to this educational event - a Live Mix recording session in the School’s recording studio! This addition was a special treat for students, area broadcast engineers, and even for Workshop presenters. The talented local band, “IRIEspect”, set up and played in the performance studio, while students and sound techs set up mics and configured the recording console for a recording session. We learned important points about mixing for live sound and for recording, and the performance was later replayed on WRHU-FM, the award-winning Hofstra University station. Chris Tarr, who mixes live sound weekly, joins Kirk to interview Andy and Steven on this extra-fun episode of TWiRT!

When the Archdiocese of Hartford needed to replace an audio mixing console, Tom Ray was ready. Due to parts shortages for older audio consoles, Tom chose a new console that uses Livewire Audio over IP audio in and out connections, plus networking to the rest of the facility’s studios. The result of using AoIP technology? A super-quick replacement and configuration of the new console! In the episode, radio engineer and consultant, Tom Ray, takes us on a tour of WJMJ and the Office of Radio and TV of the Archdiocese of Hartford, Connecticut, and discusses the quick work afforded by AoIP audio networking. Plus, you won’t want to miss the “ABIP Horror Story” at the end of this episode.

With broadcast engineers from 24 states - some from Alaska - there’s no better place for expanding knowledge while seeing old friends and meeting new ones that the WBA Broadcasters Clinic! What a blast to broadcast live from the SBE booth in the expo hall, and we trapped a number of guests to talk about new tech and best practices at this year’s Clinic. Plus, we get to see how the grand prize winner is picked in a Poker-like game with lots of participants! Who won? Watch and see!

On Wednesday, October 4, 2023, broadcasters and wireless carriers participated in another National Program Test of the EAS and WEA systems, alerting the public in a variety of ways. Initial reports are that this nationwide test was rather successful! Past tests have been plagued with audio problems for broadcasters, but this test primarily utilized the CAP Server system, delivering clean audio to most broadcasters for retransmission. Chris Tarr serves on Wisconsin’s State Emergency Communications Committee (SECC) and brings useful insight into this recent test. Plus we’re talking about fiber-delivered Internet service and its much wider availability. Plus, thinking creatively about siting FM translators or STL hop locations by looking for lesser-used towers or those not currently associated with broadcast functions.

When Jeff McGinley’s radio stations in Portland, Oregon, joined the ranks of the “homeless” last year, he had just a few weeks to create virtual radio infrastructures so the on-air talent could keep working, doing live shows. Even after moving into new “hands-on” studios, the Portland group is still using virtualized radio consoles for both regular and special broadcasts. Now Jeff is building another virtual studio for a country music star’s restaurant in Gatlinburg. Meanwhile, Chris Tarr and Kirk Harnack have built out virtual broadcast infrastructures benefitting their companies’ stations as well. Come along as we describe and even demonstrate some of this virtualized tech that’s making broadcasting easier than ever.

How do you provide electric power to your FM translators when, 1) It’s really expensive, 2) Commercial power isn’t reliable, 3) The public depends on your service working? KCAW-FM is installing both solar- and wind-generated electrical systems at their translator sites, serving tiny towns and villages in the archipelago of Southeast Alaska. Becky Meiers with KCAW, and Pete Tridish, a longtime consultant to low-power, community, and startup broadcast radio stations both join Chris Tarr and Kirk Harnack to explain the motivations for and approaches to renewable power sources for these FM translators.

For thirty-two years John Bisset has uncovered and shared some of the best ideas in broadcast engineering techniques, useful supplies, and best practices. Every few months John joins us on TWiRT to share the best tip and tricks. Today we’re with John in-person in the new “Wolf” control room of WIWF-FM in Charleston, South Carolina. Cumulus Regional DoE, Justin “JT” Tucker is here, too, for a quick tour and story about this new studio, built on Audio over IP technology from Axia.

The LPFM (Low Power FM station) filing window is almost here. Hundreds of organizations are expected to apply for new licenses to serve their local communities. LPFM is a curiosity to many, and a very serious undertaking to many others. Michelle Bradley is an LPFM expert, amateur radio operator, software developer, and a real advocate for FCC Rules and legislation designed to support community-level radio broadcasting. Our conversation is fascinating and informative! We’re delighted to have LPFM radio advocates like Michelle, whose technical knowledge informs her regulatory advocacy work.

How did YOU get started in broadcasting? We each have a story. Rob Grayson’s older brother, Walt, received an AM transmitter kit for Christmas in the 1960’s, and that got both Walt and Rob started on careers in radio and TV. Rob even took his 3rd Class FCC license test with Bob Pittman, who went on to be CEO at iHeart. So many twists, turns, and stories to tell, both from the engineering and the operations and programming sides of radio.

We often ask and worry about the next generation of broadcast engineers. Andy Gladding leverages his ties to Hofstra University in New York to encourage students to prepare for careers in broadcasting, including broadcast engineering. And he’s helped a number of Hofstra students move into broadcast careers. Chris Tarr, a popular SBE Mentor, and Andy discuss finding and encouraging our next broadcast IT and engineering professionals.

It’s been 10 years (wow!) since the FCC opened an official filing window for new LPFM radio stations. The FCC’s press release states: The Media Bureau (Bureau) announces a filing window for applications for low power FM (LPFM) new station construction permits. The filing window will open at 12:01 am EDT on Wednesday, November 1, 2023, and close at 6:00 pm EST on November 8, 2023. The window is available for LPFM proposals in the entire FM band (channels 201-300). Our guest is Dave Doherty, a broadcast engineering consultant who has assisted many applicants in getting their own radio stations. Dave joins us to describe not only the FCC’s application requirements and process, plus a channel search tool at the FCC’s web site, but also to show us the value of using mapping techniques to further identify LPFM placement opportunities.

Despite the hot weather, we know that summer will be fading into fall for us in the northern hemisphere. Josh Jones with Maxx Konnext Group joins us to talk about a production room he’s just finishing up. Chris Tarr is on the show, live from Magnum Media’s data center, and Kirk shares photos and thoughts on a new FM station that’s built with everything at the transmitter site, including the on-air phone system and the audio console. What are your thoughts on Kirk's "main studio" build?

Interoperability - what does that mean? After this 1-hour conversation with Robbie Green and Chris Tarr, I would say it means “controlling or checking on one device by using another device or system”. Scaled up intelligently, it implies having control and understanding of complex systems from a single location, or doing so automatically. So, rather than separately checking on an automation system, an audio processor, an audio router, a satellite receiver, a transmitter, or a security system, these individual systems can connect meaningfully to a central monitoring and control (M

FreePBX is an open source SIP PBX software application used in many thousands of businesses, including broadcast facilities. Tony Lewis is the entrepreneur behind this amazing software, and he joins Chris Tarr and Kirk Harnack to discuss the benefits and uses of VoIP telephony. Tony recently founded ClearlyIP.com, a provider of SIP telephony services and equipment, with expertise in high-volume inbound calling, needed by so many broadcasters.

Frank Martin is a thoughtful and insightful broadcast engineer with decades of radio and TV experience. And, he’s sharing some compelling ideas with us on this episode of TWiRT. Based in Los Angeles, California. Frank provides service, integration and support for TV, AM, or FM transmitters and studios. Today we’re discussing a new LPFM filing window (Nov 1 - 8, 2023), ATSC 3.0 television, “Franken FM” stations, C-QUAM AM stereo, and whether market size and career satisfaction are related. Plus, Frank has some final thoughts inspired by The 10 Principles of Burning Man.

The FAA compliance rules for your tower’s obstruction lighting continue to be updated as evidenced by a November 2020 FAA circular. Bear Poth, President

Dan McQuillin, Managing Director at Broadcast Bionics, joins us to explain the philosophy behind Virtual Rack, and further explain how backup and failover is implemented with similar ease.

Kirk Yano is a multiple Grammy-winning recording engineer with well over 30 Platinum and Gold records. He has won three Grammys including a Grammy for the last album that Miles Davis recorded. He has worked with Public Enemy, Mariah Carey, Miles Davis, Madonna, Michael Jackson, Placido Domingo and Phoebe Snow, and has toured as a musician with Snow, Savoy Brown, Scott Holt and Texas Scratch. Kirk was the recording engineer for “Fight the Power’ by Public Enemy which Billboard magazine still lists as one of the most influential recordings. He was also the engineer on Mariah Carey’s Christmas Album and her Jewel Box album and he worked on History by Michael Jackson. We'll hear about Kirk Yano's first visit to Nashville and his early association with Steve Church and Frank Foti. And even how Steve Church sometimes stayed at the "Yano Arms Hostel" (my name for it) in NYC in Steve's early phone hybrid days. Plus we'll hear about WMMS remotes that Kirk worked on with Frank in the late 1970's. Finally, we'll understand part of the reason that music started to get really processed in the early 2000's, and how Kirk worked to mitigate the craziness in the music industry, or at least turn it into something musical and useful. Also, what about the production transition from multitrack tape and mixing consoles to digital DAW production?

When Chuck Kelly recommends a new technique or technology, it’s important to pay attention. TX-Control is a networked and cloud-based monitoring, alarm, analysis, and control system designed for broadcast equipment. In Europe TX-Control is monitoring over 1,500 transmitter sites, providing custom reports on trends, outages, automatic remediation, and more. It leverages SNMP, a monitoring and control protocol which is built-in to more and more broadcast equipment. Chuck is joined by Aimé Diattà to help us understand this technology and service that’s watching over critical broadcast infrastructure.

Charles Kinney and David Bialik are here to hash out the apparent demise of the AM Radio Band. As bad as some say? Worse? Or still quite viable and important? Have the FCC or the NAB been helpful, or harmful to AM Radio? Is there legislation that would help the AM Radio service? Are there technical improvements that haven’t been implemented yet? Both David and Charles have extensive experience in engineering for large AM stations, and they’re both avid listeners. Salient comments and some good ideas are just ahead, on TWiRT!
