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.

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.

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.

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.
