    TWiRT 514 - Wildfire! with Mike Everhart

    Being Director of Engineering for a large radio broadcaster is challenging enough these days. Doing that while fighting forest fires is downright heroic! Mike Everhart is Director of Engineering at Alpha Media AND he fights wildfires. We’ll see the incredible damage done to a steel-walled transmitter building and its contents, plus the clever replacement shelter to get back on-air just 3 days later. Finally, David Bialik joins us with highlights of the on-demand sessions available in the Broadcast track of this year’s AES Show.

    TWiRT 513 - A Lifetime of Achievement with Mark Persons

    TWiRT 513 - A Lifetime of Achievement with Mark Persons

    In fifty-six years the Society of Broadcast Engineers (SBE) has awarded only ten John H. Battison Awards for Lifetime Achievement. This tenth and most recent one was just bestowed upon Mark Persons, CPBE, CBNT, AMD. Since Mark got started in radio and had an engineering curiosity from an early age, we wanted to know about his early experiences that have informed his career as a broadcast engineer. Mark takes us through his early years and military duty, and describes how he “never had a Plan B”.  Also, AES Past President, John Krivit, tells us about the 7 Audio Wonders of the World Tech Tour.

    TWiRT 512 - Brace Yourselves, Winter is Coming with Paul Montoya

    TWiRT 512 - Brace Yourselves, Winter is Coming with Paul Montoya

    Preparing for winter is a time-honored ritual in most temperate climates. Most of the USA - indeed most of the world’s population - fall in temperate zones, and that means winter weather is likely or possible. The “business end” of broadcast equipment is often exposed to winter weather. Paul Montoya, Director of Engineering at Wyoming Public Media, oversees operations and maintenance at transmitter sites that are difficult to access and exposed to harsh conditions while being considered “critical infrastructure”.  Paul joins us to discuss preparing for winter’s harshness to stay on-the-air - and to stay safe.



    Show Notes:

    TWiRT 510 - Automated TV Worth Watching with Stan Walbert

    TWiRT 510 - Automated TV Worth Watching with Stan Walbert

    Automated live video production is now arguably as good as human-directed switching - at least for “visual radio”. Stan Walbert, President of Multicam Systems, has created an AI (artificial intelligence) video switching engine that emulates the best decisions of human video technical directors. Stan and Mary Ann Seidler are here with real-world examples of AI-controlled vision switching, along with advice for radio broadcasters wanting to add visual radio or improve their current systems.
