SBE needs to correct its web page, some stuff is just wrong, and some
we now know more about.
The header tones are not being played fast. They are at the expected
bit rate, which is 520.83 bits per second. The alert sounds fast
because each header has been shortened, resulting in an invalid EAS header.
Unless anyone has evidence to the contrary, the "tripping" of EAS
units affects only one manufacturer.
Unless anyone has evidence to the contrary, the manufacturer in
question unmutes the local speaker, and prints a message with a
partial alert on its printer, but does not relay the alert on air.
At least Sage and Trilithic have checked in with word that their
units are not effected.
The cause for concern here is primarily one of false or deceptive
alerts transmitted to the public, over a medium where the public
would normally expect real alerts to be delivered, desensitizing the
public to actual alerts. The confusion with speakers unmuting and
printers printing is limited to one manufacturer and is an annoyance
to radio station personnel, but has no risk of going out over the air
and into the daisy chain relay system, and there is no risk that
anyone would take the "alert" as an actual alert.
Note that, in this instance, the alert was invalid, perhaps made
intentionally so by the authors of the ad, but equally likely to have
simply been shortened for ad length. The next time, someone might
use an actual valid alert, which could case larger amounts of grief
depending of the contents of the eas header used.
This is clearly a "teachable moment".
