TWiRT - This Week in Radio Tech - Podcast

How many things can you monitor at your broadcast facilities? And how many different systems do you have to check to know whether everything's working properly? Today's technology makes it possible to bring an extraordinary amount of information together into one convenient dashboard, giving broadcast engineers and station owners a network operations center of their own. From transmitter health an...

What can a recording engineer teach a radio engineer—and what can radio teach someone behind the recording console?

Today’s broadcast facilities depend on far more than transmitters, RF systems and studio audio. Engineers are now responsible for Ethernet networks, Windows and Linux computers, cybersecurity, virtualization, streaming, metadata, AoIP, remote access, cloud services—and countless devices that are essentially computers wearing broadcast-equipment clothing. In this episode Kirk Harnack ex...
