TWiRT 706 - Crowdstruck by Crowdstrike

As we are all very aware, being a technical person or layman, the recent CrowdStrike outage caused disruptions on a myriad of computer systems worldwide, affecting multiple industry sectors and millions of people in some way, shape, or form. Approximately 8.5 million devices were affected, leading to outages in various sectors, including airlines, healthcare, and financial institutions. Some broadcasters were affected, but it seems most radio broadcasters were spared. Why is that? What crippled many very large industries had relatively little impact on radio station operations. Three experts join this TWiRT episode: Shaun Dolan, Kyle Walker, and David Smedley. Together we’ll uncover how Crowdstrike affected some broadcasters, and we’ll learn about some best practices for IT security.

TWiRT 704 - Dogs & Cats Living Together with Larry Janus

Larry Janus is no stranger to broadcast engineering, but his passion is excellent design of vacuum tube based audio circuits, and then controlling their functions using modern control electronics via WiFi. This passion leads to a clever integration of a tube-based mic pre-amp, fully remote controlled using a phone app over WiFi.  This arrangement gives rise to some interesting and convenient possibilities for stage-placed mic pre-amps with remote control. Larry Janus joins us from his well-equipped home lab in Florida.

TWiRT 702 - EAS at the Edge with Bill Robertson

U.S. Broadcasters are required to provide emergency alerts to their audiences, but many radio stations use IP-based signal distribution — something incompatible with old-style EAS boxes. What is needed is a simple way to interface the real-world over-the-air reception of EAS events, filter and process the messages, and — if necessary — incorporate the alerts into the modern audio-over-IP (AoIP) air chain. Doing this right involves some innovation, but once done well, there are several distinct benefits. Bill Robertson from Digital Alert Systems joins Kirk Harnack to explain how this award-winning implementation works, and why it makes EAS better and more effective.
