"Hacking" the Dallas tornado siren network...

[Nan and Sandy Sanders]

Most of the systems around here (120 miles east of Dallas) are radio 
based. The system here in White Oak sounds like a packet system on 
the fire repeater. Two way with telemetry back from the sirens. The 
next town over uses a similar system ( and just set their system off 
for real a few minutes ago, the weather here is interesting tonight). 
I always wondered if a playback attack would work.
I just checked and WFAA just put this story up
