EAS, or more properly, the Emergency Alert System, is a government mandated system of encoders and decoders designed by the federal government to alert the public in case of war or other emergency.  It, and it’s predecessor, EBS (Emergency Broadcast System) have never been activated by the federal government.  Both systems, however, are used extensively by local and state governments for things like weather alerts, amber alerts, etc.

Back in the mid-90’s the FCC had a chance to redo the EBS and produce something that was a streamlined and effective tool for public warning.  Unfortunately, the EAS system is neither.  Rather, it is a cumbersome system of weekly and monthly tests scheduled around pre-conceived notions that how the system is tested every week will be how the system works in an emergency.  In practice, this is generally a good theory of system design, but it has failed miserably with EAS.  The reasons why are thus:

  • Most all emergencies are local or at most state wide events.  To this day, very few state and or local government emergency managers would be able to activate EAS for their area.  The reason is there is minimal if any interface with the LP-1 EAS stations or station personnel.  Ignorance and apathy on behalf of both radio station personnel and government officials is the main culprit.
  • Most stations are un-maned for large portions of the day.  Even if government official could/did call the station, chances are, nobody would be there.  If by chance, arrangements were made to contact station employees at home, they would have to interface with the EAS equipment remotely, which ads complexity to an already complex system.
  • EAS messages are still mainly relayed from radio station to radio station, the so called daisy chain net work that has been shown numerous times to be unreliable.
  • The system of SAME codes, FIPS identifiers is not necessarily bad, the application in this case leaves something to be desired.  The FCC had a chance to update EAS before the HDTV rollout.  One would assume that any improvements could have been built into the new TV sets that are now being sold, but again, that opportunity was missed.  For example, I suggested that each TV have a set up screen option where the owner could input their zip code.  They could also choose what types of alerts they would want to know about and even base the alerts types on the time of day.  Live in a flood zone, the FFW (Flash Flood Warning) 24/7.  Live in tornado alley, TOR (Tornado Warning), etc.  The cable companies then pipe in the local NOAA all hazards radio station.  All the sudden there is a real national alert system in place using mostly non-broadcast wireless systems.  Add to that the ability to sign up for emergency e-mails and text messages for specific areas (many places are currently doing this) and there is multiple message paths.

The system as is is not reliable and sooner or later that will be shown with a large scale failure.  Recently, the FCC held a summit with the Department of Homeland Security.  The cliff notes version of this event is: Yes, the system can be made better.  Let’s keep throwing the same ideas at the wall and see if anything sticks this time.  Excuse me if I don’t do back flips, this is the same information that was discussed during the last “lets revamp EAS” discussion back in 2005 (04-296).

In the mean time, the EAS continues to be a good fund raiser for the FCC enforcement bureau.  Which, you know, it is easier to go to a licensed radio station and bust them for not re-transmitting the RMT (Required Monthly Test) than it is to go out and bust some of the numerous pirate radio operators, some of whom are operating in the same city/metropolitan area as a field office.

The shame of it is, it could work without a great deal of cost, very well.
