TWiRT - This Week in Radio Tech - Podcast

Boasting 17 signals in 4 radio markets - in New York and Pennsylvania - Radigan Media represents the kind of local radio that’s not only serving its local communities, but doing so with newer technologies. Dave Radigan wears many hats in his growing network of stations, including Chief Engineer. He’s implemented Audio over IP (linear Livewire) between studio and transmitter site, partly because he needed a bi-directional link with no audio compromises - and contact closures. And, Dave has recently opened the door to the “flexible studio”. Using AoIP audio routing tech he’s providing his staff with convenient options for live talk shows, voice-tracking, and production from the same studio, as needed. Let’s check out Dave’s reasoning about implementing the latest tech, when it makes sense to do so.

Many radio engineers love to visit other radio stations. We get ideas to perhaps implement in our own stations. Or sometimes we may get a sense of satisfaction thinking that we’ve done a superlative job in our own facilities - compared to others. Today we’re honored to visit the studios of 100.1 FM in Santo Domingo, Dominican Republic. OMG! What a drop-dead gorgeous studio! Rafael Recio is the Chief Engineer at 100.1 FM. He shows-off this beautiful and effective working studio, which is home to live shows in morning and afternoon drive every day. Rafael worked with the station’s Program Director, Harold, to design and build this world-class radio studio + control room. Show Notes: Time Lapse video of 100.1 FM’s studio construction Rafael is using Axia iQ AoIP audio mixing consoles. 100.1 FM - “Santo Domingo’s Greatest Hit Music Station” We mentioned the Museo de los Telecomunicaciones, noting the early and continuing technical advances in the Dominican Republic.

Chris Tarr just finished a long-anticipated FM transmitter move. Big implications attended this move all the way across a metro area. The new site needed a directional FM antenna, and they decided that a new transmitter made more sense than moving the old one. Chris covers a lot of ground when contemplating any transmitter site move. Kirk Harnack touches on a few pointers for IP radio microwave links, including not trusting the existing infrastructure too much! Show Notes: Planning Transmitter Moves Facilities - Building, road, fencing, parking, HVAC, roof, ice protection Legal including FCC Permitting - local zoning, building, etc. Safety - fencing, insurance requirements, guy anchors, tower base STL considerations & options Frequency coordination for 950 & IP STLs Fiber internet availability AC Power - service sizing, etc. Executing the move What can be built and ready beforehand What has to move overnight or a weekend Absolutely no off-air time? Or minimal? Actual cutover Moving audio processing if needed What if something goes really wrong? Plan to go back if needed? After the move (should have been before the move) Tying up all the loose ends Grounding, lightning protection Putting redundancy in place at the new location What if Internet installation is late? Wait or move ahead?

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. Show Notes: Joyce appears on another podcast, Working Class Audio #304 More information about Joyce is found on this page about the SZALON Tech Team Guest: Joyce Lieberman - Radio Engineering Supervisor at WHYY, Philadelphia Hosts: Chris Tarr - Group Director of Engineering at Magnum.Media Kirk Harnack, The Telos Alliance, Delta Radio, Star94.3, & South Seas Broadcasting Follow TWiRT on Twitter and on Facebook TWiRT is brought to you by: Nautel’s new GV2 FM transmitters are here - chock full of features!
