Category: Emergency Alert System (EAS)

Came over the wire just a couple minutes ago.

I originated this alert a short time ago (as of writing this post.) This is a recording of my original relay, plus a relay from GWES EAS Relay Network southeastern core station ERN/KLT in Miami Florida. (Northeastern core station ERN/JON in Fairfax VA doesn’t relay EAS originated ADRs.)

Pinging Matt: This is what happens when you have a small telescopic antenna connected to a three-way coaxial splitter, held to the back of a server rack with Dollar General knock-off duct tape, and the tape fails.

Until May 2025 the endec that ran ERN/KNA was a SAGE 1822 graybox unit. These began production around 1996 and continued presumably until the introduction of the bluebox in 2008. This was a relay of a WBAP originated Texas AMBEr Alert on March 24, 2025. The unit is still around, but its likely broken now.…

I did my best to make this mockup as period correct as I could. The TTS engine is the National Weather Service variant of DECtalk, I used a period correct EAS encoder, and I even found a station ID from a station in the area from that time online. Admittedly, this alert would have likely…

My best friend asked me to create an unrealistic EAS mockup several months ago, so I spat this out in about an hour. This was where I finally started to find my stride in mimicing the sound of broadcast radio, starting with AM. This is what made me develop my AM Radio macro for Audacity.…

I own a second EAS encoder unit, it’s a HollyAnne HU961 from the mid to late 90s, and I’ve given mine the nickname of the Shit Biscuit. It’s tiny and terrible. It requires an external audio switcher, uses a 1/8 inch (3.5MM) TS mono headphone cable for power, and only records audio at a 5KHz…

This was at the end of a Life Threatening Flash Flood Warning in New Mexico. This is terrifying wording!
