Send me a text!

Those jarring tones that interrupt your favorite radio and TV programs aren't just annoying interruptions—they represent a complex, life-saving system with a fascinating history and critical importance to public safety. Fully Modulated returns with an ambitious new season dedicated entirely to unpacking the Emergency Alert System.

Your host Tyler brings years of broadcast engineering experience to guide you through this vital yet often misunderstood technology. From its Cold War origins as a defense against potential nuclear threats to its modern digital transformation across multiple platforms, we're examining every aspect of how emergency information reaches you during critical moments. What happens when these systems fail? How have false alarms like the 2018 Hawaii missile alert shaped improvements? Why do those distinctive tones create such a visceral reaction in listeners?

This season offers something for everyone—broadcast professionals will appreciate the technical deep dives, while curious listeners will discover the surprising stories behind a system we encounter regularly but rarely think about. We'll explore how emergency alerts have permeated popular culture, the psychological engineering behind their attention-grabbing design, and what the future holds as climate change increases the frequency of emergency situations requiring mass communication.
