The Public Radio Engineering Conference (PREC) seems to get better and better each year. Attendees were frequently held in wrapped attention by captivating and informative presentations about audio and RF technologies and techniques. Our guests on TWiRT each took a few minutes away from the conference sessions to give us their impressions of the technologies being discussed and what’s ahead for Public Radio Engineers.

Search the web and you’ll find hundreds of articles videos - and thousands of opinions - on the best mics to use for radio and podcasting. One of our sponsors is Angry Audio, makers of two novel mic processors to improve and control the sound of two popular microphone families. Our longtime friend and colleague, Cornelius Gould, designed the audio processing algorithms behind these specific mic processors. “Corny” joins us to talk about this rather unique approach to mic processor design and implementation. Plus Tom Ray pops in to discuss microphone choices with Chris Tarr. Plenty of opinions and some solid advice!

Can you imagine installing 60 broadcast transmitters over the past 8 years? Robert Combs, Corporate Director of Engineering at Cumulus Media has been doing exactly that. Transmitters of all sizes and from several major manufacturers. The most recent transmitter replacement is at WZYP-FM in Huntsville, Alabama. Market Engineer, Dominic Mitchum, is taking care of much of the local work and logistics, alongside Robert’s work. The project also includes replacing the RF coaxial transfer switch, main coax, and even the main and backup FM antennas. Robert and Dominic give us a very informative video tour and discussion of this project on Capshaw Mountain. Plus, Chris Tarr relates his own recent transmitter installation experiences and has developed some advice on purchasing used transmitters.

Over 50 years ago, Mike Dorrough introduced the Discriminate Audio Processor - the DAP 310. Broadcasters that cared about audio quality started buying and installing DAP310s to improve the audio quality of their stations. Five decades later these old audio processors are still in demand - as are services to supply parts and repairs. Randy Swaffer and Mike Phillips are two DAP310 enthusiasts - and they know all about repairing and aligning these classic units. Jordan Tuck also joins us to talk about refurbishing other broadcast gear, including a Continental Electronics FM transmitter and an A-6000 audio console.

Most broadcasters either own towers or lease antenna space on them. But only the tallest towers are outfitted with elevators to bring workers and light tools up to desired working levels without spending half the day getting tired from climbing. Jim Tiner is CEO at Tower Elevators Systems. His company has built many towers - short, medium, and tall - and many of the tallest ones also have a custom-designed elevator system. This elevator technology is often applicable to other tall structures, such as bridge towers, smokestacks, and even the Statue of Liberty. Jim Tiner presents his company’s fascinating story and tells us about unique elevator designs.

Most of us in radio have heard Fresh Air, hosted by Terry Gross on National Public Radio. Joyce Lieberman was the first technical director behind this well-produced national interview program. But Joyce’s engineering and production career started several years earlier, getting a kick-start when some other engineers called in sick. At the onset of Joyce's radio work, she recorded Terry Gross and her guests when Fresh Air was a local Philadelphia three-hour program. Her attention to audio purity and detail prepared Joyce for other audio engineering achievements, including working with a team at WHYY and NPR to restore and digitally archive the episodes of Fresh Air, plus provide guidance to other archival efforts. Chris Tarr adds his expert insights as well to this interview with Joyce Lieberman.

Are you one of hundreds of broadcast engineers who have attended the Alabama Broadcasters Association (ABA) Engineering Academy? Larry Wilkins and Frank Giardina are completing the 2024 Radio Engineering Academy with attendees ranging from “new” broadcast engineers to some seasoned pros looking to update their knowledge. We’re live from the ABA Headquarters near Birmingham, AL, with Larry Wilkins, ABA President Sharon Tinsley, and a few of this year’s attendees.

Current technology education and career advancement are both available at the SBE Ennes Workshops, offered at the NAB Show in Las Vegas.  The dates are April 12 & 13, just prior to the NAB Show Expo Halls opening. We’re talking with David Bialik and Fred Willard, who have assembled what appears to be the most useful and beneficial set of programs in two technology tracks.  There’s an RF101 Bootcamp track. And the subject of this TWiRT show - the Media Over IP track.  Watch the show and click on the link to SBE’s full description of these technology tracks. This is a very worthwhile 2-day workshop for any level of broadcast engineer!

Chris Tarr and Shane Toven are discussing a critical topic - especially for broadcast engineers. It’s our work/life balance with emphasis on “life”. How’s your mental health? No, really, how is it? Why is it key to “put on your oxygen mask before helping others”? Why is it OK, and even smart, to let things fail sometimes? Should engineers always strive to “be the hero”? And what’s your value - financially and otherwise? Finally, do you know that some engineers would rather fight than be helpful? Perhaps we’ve each done that, but let’s identify it and not make it a habit. Join us for this episode of TWiRT - it may be more important than any technical discussion.

People who know Alex Hartman realize that he tends to be way ahead of the pack. Alex is typically just beyond the cutting edge of technology implementation. That often makes his comments hard to understand. But when you get to know Alex and understand his ideas and concerns, they usually do make very good sense. He’s also good at “breaking things”, revealing weak points in design. Today we’re discussing people, skills, and the uncertain future of talent sourcing. Alex has some real concerns and ideas about this. In his position at Wisconsin Public Media, Alex is hands-on with basic audio tech, but also data centers and managing fleets of equipment, computing, and sometimes people.
