31 DEC 2021 · Sam Woo owns a media content and consulting company, Primetime Radio. He collaborated with former TWiRT co-host, the late Chris Tobin, on technical improvements and logistics for producing the “Let’s Go Devils Podcast” as well as corporate events and more. Sam joins us to talk about his collaborations with Chris Tobin, and to show us the “Menlo” that Chris Tobin often used for his appearances on TWiRT. Since Chris Tobin’s passing, Kirk Harnack has been hosting TWiRT solo for the past year. Kirk recently invited an engineer familiar to many of us, Chris Tarr, to rejoin TWiRT as a regular co-host. To our delight, Chris Tarr has accepted the invitation and will be on TWiRT regularly! Chris Tarr also joins us on this episode to fill us in on highlights of his engineering work in 2021.
Show notes:
* Chris Tarr mentioned LUCI software for live remote broadcasts* Sam Woo produces the Let's Go Devils Podcast* The Let’s Go Devils Podcast get rather rowdy. See this video and watch for Chris Tobin and Sam Woo in the video.

24 DEC 2021 · A few AM station owners have turned their licenses back into the FCC, giving up on their AM radio business. Many other AM station owners, however, are looking for ways to profit from their AM transmitter site property, or to reduce transmission site costs. Co-locating with land mobile and cellular towers using an inexpensive slant-wire feed for the AM station may be a solution for some AM station owners. There are other financial mitigations as well. Benjamin Dawson and Stephen Lockwood from Hatfield & Dawson Consulting Engineers join us to discuss the possibilities.

17 DEC 2021 · Is the Mayor of Verona, NJ, doing the engineering work at the top stations in New York City? Or, is the CTO at those top-rated stations moonlighting as a New Jersey township mayor? Either way, you’re right. Alex Roman leads a staff of engineers and IT pros at WQHT-FM and WBLS-FM in New York City. He says that “radio IT” is the same as “regular IT”, and we all need to work with that notion. Alex reveals other insights and techniques for broadcast engineering, remote workers, and lots of outside broadcasts on this episode of TWiRT.
Show notes:
* HOT97’s YouTube channel showing much of their video production* Alex mentioned E2X transport for HD Radio channels over IP* Ha! We talked about the Blue Yeti on this week’s show, too!

10 DEC 2021 · A real pioneer in deploying digital audio sources, infrastructure, and transmission in the UK - and even worldwide, Quentin Howard is our guest on this fascinating episode of TWiRT. Already a Fellow of the Institution of Engineering and Technology, Quentin was further honored as a Fellow of the Radio Academy in November, 2021. We’re discussing the first uses of Compact Disc digital audio in the UK, as well as the UK’s first use of audio processing on FM broadcasts in the 1980s. DAB rollout and the subsequent DAB+ ratification and rollout are also among our topics. We round the show out with what may be the perfect radio format for many TWiRT fans - Boom Radio!
Show notes:

3 DEC 2021 · Vacations are important - for our well-being, sanity, restfulness, and more. But Shane Toven just can’t stop thinking and talking about broadcast engineering and the technologies that attend it! From the enormous cruise ship, “Majestic Princess,” Shane joins us via SES satellite link using their O3b Networks technology. So, what do you talk about with a man on vacation? Food? Ports of call? Tracking tags? Tower sites? Staying connected to work? Satellite data transport technology? Yes!
Show notes:
* O3b Networks (Wikipedia) - Global coverage Internet access from medium earth orbit satellites* O3b mPOWER web site from SES* O3b mPOWER site explaining rationale for medium earth orbit coverage* “SES” is an acronym for Société Européenne des Satellites* Live map of the Majestic Princess* Another live map of maritime traffic along the West Coast of Mexico* Article about wearable RFID tags for cruise passengers and more

19 NOV 2021 · Many broadcast engineers have implemented "structured wiring" within their facilities. Some, like TWiRT host, Kirk Harnack, haven’t really jumped into the best practices yet. Ed Bukont, owner of E2 Technical Services, both consults and integrates facilities. His vast experience with structured wiring in broadcast plants makes for solid information that we engineers need to know. And, he's got Kirk convinced to "do it right" on his next project.
Show notes:
* E2 Technical Services* Nice structured wiring catalog from CableToGo (PDF)* Ed mentioned “Top of Rack” cabling - here’s info on cabling approaches* TIA568B pinout standard* TruCable offers instruction on many structured wiring and cable topics* Video playlist covering structured wiring in a commercial setting* CableSupply.com has good videos on every aspect of structured wiring

12 NOV 2021 · Necessity may be the "mother of invention", but Gordon Carter never thought necessity alone was good enough. As Chief Engineer at classical station, WFMT in Chicago, Gordon's broadcast audio systems had to sound impeccably great, yet withstand the rigors of 24/7/365 broadcasting in America's 3rd largest radio market, Chicago. Let’s learn together from Gordon’s pursuit of audio excellence in FM broadcasting.

5 NOV 2021 · In our radio broadcasting world 100% modulation (or more?) has been the goal for decades. However, we now find ourselves entering a new paradigm where consistency and quality eclipse loudness as an audio level objective. What do units of audio loudness mean? If 0 dB isn’t the goal, then what is? -16 LKFS? John Kean is a leading expert on perceived audio loudness, plus he’s a prominent broadcast engineer. Let’s hear from John and understand what this world of audio loudness sounds like and find out why it’s changing.
Show notes:
* AES Technical Document AESTD1008.1.21-9* BS-1770: Algorithms to measure audio programme loudness and true-peak audio level* Dolby: Guide to Loudness in Media* More information on BS-1770 loudness measurement from Meterplugs.com* ProTools: AES Update Loudness Recommendations For Audio Only Streaming

29 OCT 2021 · Common Alerting Protocol. Doesn't sound exciting, but what it's doing for people in many countries is sometimes life-saving. We might think of CAP as a new-ish way to receive emergency messages, such as Child Abduction Emergency notification. Or we may consider CAP as just another input source to our broadcast EAS systems. There’s a lot more to CAP than this, however. Interestingly, the USA and Canada are using CAP a bit differently. Rob Hopkins from OpenBroadcaster in Canada, and Vincent Maggard, a software developer, join Kirk Harnack to explore and explain what CAP really is and how it’s used.

22 OCT 2021 · Many radio engineers are talking about “cloud” and “cloudified” broadcast infrastructure, and inroads are being made right now. One group of broadcast technologists and developers is now running over 100 radio stations in Germany, fully with cloud-based infrastructure. Radio.cloud is designed to supply a backbone of audio programming from data centers, with local customization for each market. Some of that customization is done with Artificial Intelligence, or “AI”. Christian Brenner, Jim Hammond, and Tony Lorino join us, each with a different perspective on Radio.cloud’s technology and capabilities.
