[EAS] EAN redux - FEMA

[Sean Donelan]

As far as I've seen, the chatter has been aspirational or delusional. 
Nearly all of the chatter has technical misunderstandings of the 
procedures.

Considering only the technical issue of a rogue EAN, and not the 
associated legal or political issues; DASDEC, Sage and Trilithic have 
procedures to abort (cancel) rogue EAN messages and correctly restore 
downstream EAS daisy-chain stations. Please see their respective manuals 
for the procedure.  It is deliberately more difficult to abort an EAN, 
but all manufacturers have a documented procedure.

You should NOT unplug your EAS box or audio cables.  If you choose, for 
whatever reason, to abort (cancel) an EAN, your EAS box still MUST 
transmit the End-Of-Message (EOM) codes.

State and Local Primary stations should also transmit a RWT immediately 
after an EAN message abort (cancel) to help clear any downstream hanging 
stations.

Again, the chatter is full of technical errors and seems to aspirational 
or delusional. But being prepared doesn't hurt.  For grins, North Korea 
decided to hold a military parade on Sunday.
