The Emergency Broadcast System, also called the Emergency Action Notification System was an emergency warning system used in the United States from 1963 in which replaced the CONELRAD and up until 1997 where it was replaced by the Emergency Alert System. However, as the EBS was replaced by the EAS, recordings of EBS Tests & Warnings have become obscure and very hard to find.

EBS Broadcasts

EBS Stress Test (1963-1976)

During the early days of the EBS, stations would turn their transmitters on and off and transmit a 1000 Hz tone for 15 seconds and announce the test message. This became known as the EBS Stress Test by broadcasters due to the repeat nature of turning their transmitters on and off and the high chance for the equipment to malfunction. [1] As of February 2018, no known recording of an actual EBS Stress Test exists anywhere on the web.

EBS Video Slides (1976-1997)

Beginning around 1976, each station was given a video card, in which various designs became available over the span of twenty years. Around 100 EBS Video Slides (Mainly EBS Tests) from all different stations resurfaced online. It's unlikely that all EBS Video Slides will ever be recovered as there were hundreds of them made for each station throughout the United States.
