Welcome to the World of EAS


You’ve no doubt heard these harsh tones on our air at random times. These tones activate a computer-generated voice that sends out severe weather warnings. The system is tested weekly and interrupts programming – sometimes at very inopportune times.

To broadcasters, it’s known as The Emergency Alert System (EAS), a national warning system in the United States. Since today is the first day of hurricane season, I thought I’d share some of its fascinating history with you.

In 1951, President Truman established the first national alert system. This system later became the “Emergency Broadcast System” (EBS). The EBS was designed to provide the President with a means to address the American people in the event of a national emergency. Through the EBS, the President had access to thousands of broadcast stations to send an emergency message to the public.

As a humorous aside, some broadcasters opted to “sing” the test (which I can appreciate!), but ultimately the Federal Communications Commission (FCC) didn’t think that was such a good idea.

In 1994, the Commission replaced the EBS with the Emergency Alert System (EAS). The EAS provides not only the President, but national, state and local authorities with the ability to give emergency information to the general public via broadcast stations, cable, and wireless cable systems.

That’s why you hear severe weather alerts such as flash floods, tornadoes, or winter storm warnings from the National Weather Service on WBHM. The ultimate goal of the EAS is to disseminate emergency information as quickly as possible to the people who need it at any time of day.

To say these alerts sound different from WBHM would be an understatement. But I guess that’s also the point. If it sounded too much like what we normally do, it’s possible potentially life-saving information might not grab your attention the same way.

As for the programming interruption, well, that’s also the point. If we knew when the test was occurring, it might not be a true test. And given Alabama’s history with severe weather, it’s a small price to pay for staying safe.

(Through “Programming Notes,” we hope to keep you connected to what is happening at WBHM both internally and on-air. Have feedback you’d like to share? Or a programming question? Let me know!)


Incoming Transmission! Pt. 2

You may remember earlier this year when WBHM held a special Transmitter Drive. With your support, we raised the final $50,000 to purchase and install a new transmitter. In total, this project cost $230,000. For this edition of Program Notes, I checked in with WBHM’s engineer Darrell McCalla who oversees this project for an update […]

Meeting You Where You Are

Last week, I attended the Public Radio Content Conference – the premier gathering for non-commercial programmers, content managers and leaders in the public media ecosystem. This was the first in-person conference in more than two years and, it was good to reconnect with my colleagues in person — not just because of the pandemic, but […]

Rise and Shine

I spent early August substitute hosting Morning Edition for Miranda Fulmore who was on a well-deserved vacation. And while everyone has their routine, I thought I’d share a little bit of what goes on behind the scenes in the very early hours of the day. I get up at 3 a.m. which also means I really try […]

There’s Lots of Moth’s in the Air

This week, I’m writing about The Moth – not the insect, the storytelling phenomenon! If you haven’t heard, The Moth is true stories told live, without notes. It’s personal storytelling that connects us as human beings. These stories are told in different ways to millions of people each year including right here in the Heart […]

Welcome Back to Program Notes!

I spent a (mostly) restful two weeks off visiting with extended family – most of us hadn’t seen each other since before the pandemic. But even on vacation, I still listen to public radio wherever I am. Sure, I could (and often do) listen online, but there’s a part of me that’s also a fan […]

Deliberate Indifference – Inside Alabama’s Prison Crisis

You’ve probably heard of our new narrative podcast, Deliberate Indifference. And, given all the heavy news the past few months alone, you may think this is the last thing you want to listen to. I urge to reconsider. As citizens, we have a right to know how more than 500 million of our tax dollars […]
