This will be the first time, ever, that all stations in the U.S. will send and broadcast a EAS test at the same time, in a chain so to speak, to see if they work connected. If an indidual station has problems, the FCC will investigate to see waht went wrong. Licensed radio and TV station general managers that fail to do the test as required can be arrested and face jail time.
The test today is the first ever national test of the EAS system, and it is the first national use of the “live code” EAN: Emergency Action Notification.
As the first test, the FCC has -informally- agreed that no penalties will be assessed for failures by stations or cable systems.
Stations do need to file reporting with the FCC so that failures can be identified and corrected.
