Status: Partially Lost

The Emergency Broadcast System (aka Emergency Action Notification System or EBS for short) was an emergency warning system used in the United States from 1963 in which replaced the CONELRAD and up until 1997 when 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[edit | edit source]

EBS Stress Test (1963-1976)[edit | edit source]

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]

Recovery[edit | edit source]

On August 27th, 2020, a user on YouTube by the name Ellis Feaster uploaded a KDKA 1020AM Radio Air Check featuring an EBS Stress Test from December of 1969. This is the oldest known EBS Test recording to date. The rare recording can be heard below.

EBS Stress Test starts at 14:55.


EBS Video Slides (1976-1997)[edit | edit source]

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.
