TWiRT 449 - Watermarking Strategy with Paul Kriegler & Dr. Barry Blesser

Radio broadcasters in so-called “PPM Markets” are faced with managing two signals for each station. One is the audio program that listeners hear; the other is the watermark signal heard by Personal People Meters (PPM)™.  Broadcasters concerned with counting their listeners (all of them in a PPM market) must treat their watermark signal with similar care to their on-air audio. In this episode, Dr. Barry Blesser explains the science of audio watermarking. Then Paul Kriegler describes the Best Practices for making sure your watermark signal is consistently detected in the field.

TWiRT 446 - Skip the Ransomware with Stephen Kurtz

The spectre of ransomware encrypting all the computer files we need to run our broadcast operations is truly scary – heart-stoppingly scary.  Ransomware - as well as other malware - keeps morphing to get around our blocking and mitigation techniques. But there are basic, important things every broadcaster can do to seriously reduce the risk of losing everything to ransomware.  Stephen Kurtz has a broadcast engineering background and is now an IT consultant. He shares current advice and tips to help you avoid the most common IT security mistakes.

TWiRT 445 - Like a General Contractor

Thinking about all the skills and responsibilities that broadcast engineers have, it seems we’re akin to General Contractors.  We have to know something about a lot of things. Disciplines from basic structural load calculations to audio circuit optimization to complex digital modulation schemes. Those and a thousand other topics are critical to the well-rounded and effective broadcast engineer.  Chris Tobin and Kirk Harnack discuss how diverse skills relate to our recent experiences.
