It's a complete overhaul the Emergency Broadcast System. It's only being done in a few areas to begin with, but there'll be a lot of reports about
it soon. Unfortunately with such a massive undertaking there are going to be a large number of errors and mechanical/technical failures to be sorted
out. Thsi would cause a lot of repeat in the signal broadcast until the errors are ironed out. Some areas have probably already been through this.
The system should take about 3-5 years to completely implement.
From 2007
Going through MERLN to find the specific legislation that started this. (that's where I found the original docs....) Could take awhile.
Just think of it this way. With the addition of the Silver and Amber alert systems, as well as the increasing usage, it was only a matter of time
before the system got overhauled. I'm glad they are doing it gradually, though. This way the whole EAS doesn't go down at once
