TWiRT Ep. 630 - New FM Site, New Swiffer with Russ Laferty

2/4/2023
Russ Laferty is the kind of broadcast engineer that more stations need. He’s from the rough mountains and “hollers” of Eastern Kentucky - Auxier, Kentucky - to be precise. But he also travels Tennessee, Arkansas, West Virginia and beyond to get broadcasters back on the air, always working to improve their equipment reliability and effectiveness. Today we caught up with Russ at the new transmitter site of WDTL-FM, licensed to Indianola, MS. It’s a second-hand prefab building at the base of a...

TWiRT Ep. 627 - Ariane, I Love You - with David Reaves

1/13/2023
Ready to learn some surprising facts about audio processing? David Reaves - known by many for the Ariane audio processor - is guest! We're talking, of course, about the famous Ariane audio processor, but also the CBS Audimax and Volumax. Did you know the Audimax had a "memory module" that was key to its “intelligent” audio leveling action? Pretty slick for early 1960's design!

TWiRT Ep. 624 - Feel-Good Audio Processing with Cornelius Gould

12/23/2022
Cornelius Gould began nearly 40 years ago considering audio processing and its effect on how we perceive music and voice. His “Chameleon” audio processing algorithms began with analog circuits, but are now fully emulated and perfected in Digital Signal Processing (DSP). What makes audio more pleasing to our ears and brains? What might a psychoacoustic expert say about the treatment of audio so we hear and appreciate it more enjoyably? Chris Tarr joins Kirk Harnack to discuss these topics and...

TWiRT Ep. 622 - TV Audio Loudness: It's Complicated - with Ken Tankel

12/9/2022
Hearing dialog on some TV shows and many movies broadcast on TV is a problem. Why is dialog often hard to hear? Radio doesn’t have this problem. And TV typically didn’t until we went digital with DTV and 5.1 audio. Ken Tankel is Kirk’s go-to TV audio specialist. Ken worked for years in radio major market radio, so he understands audio processing. But, TV audio is markedly different, with different goals, targets, and formats. But we’d still like to understand the dialog! Ken walks us through...

TWiRT Ep. 621 - 5 Things to Know About FM Transmitter Sites with Hal Kneller

12/2/2022
Some technical advice is timeless. Other tech advice changes with the times. Such is the case with FM transmitter sites. Now more than ever we broadcast engineers need to apply the right safeguards and approaches at today’s FM transmitter sites. Situated under tall lightning “attractors” - otherwise known as “towers” - FM transmitter sites need a mix of time-tested design care and contemporary precautions. Hal Kneller is a 40 year veteran of transmitter sites, and his Florida home provides...

TWiRT Ep. 620 - KOTZ is in Kotzebue with Pierre Lonewolf

11/23/2022
Pierre Lonewolf’s career journey that led him to Kotzebue, Alaska in the early 1980s. You can’t get much farther away from major population bases than northern Alaska. Kotzebue, population 3,283, sits on a sand spit of Alaska’s Arctic west coast just across the Chukchi and Bering Seas and several hundred miles from the Russian eastern frontier. It’s a scenic but scarcely populated place that features abundant wildlife like caribou and moose and bear. Pierre Lonewolf, CSRE, CNT, manages...

TWiRT Ep. 619 - Sound Engineering Advice with Dennis Sloatman

11/18/2022
“Aggressive Neglect” sounds like a great name for an Alt Rock band, but it’s actually one of Dennis Sloatman’s pet peeves. Petrified hamburger leftovers in the wiring chases is another. But he would rather construct new, reliable, yet simple broadcast systems than complain about poor work that preceded him. From continuing education to SNMP-monitored systems to small, medium and very large markets, Dennis Sloatman is the thoughtful engineer who plans the work and then works the plan. Let’s...

The auto industry has been offering after-market parts and assemblies for decades. Now we’re seeing more after-market system replacements in the broadcast industry. Mike Patton, a well-known contract engineer, is offering replacement assemblies for some popular AM and FM transmitters. These specific transmitter models are typically well-designed for long life, but now suffer from parts made of “non-obtainium”. Mike solves this with newly-designed replacement assemblies made from parts...
