For the first time since what most of us grew up with as the "Emergency Broadcast System" (This is a test. This is only a test...) a nation wide test of this system will be held on the above date. I'm accustom to this test cropping up on a monthly basis on my weather radio, statewide. To this day, that danged "tone" drives me insane...I have hearing like a dog, evidently.
For approximately 3 minutes the airwaves across America, from t.v. and radio, to satellite, etc. will conduct this test simultaneously. Try here for more information on this test.
Although not overly publicized at the moment, I'm glad to have discovered this now, rather than worry terrorists had taken over the airways. I only hope the EBS gets an A+.
Not so sure picking the date 11/9/11 was such a reassuring influence.
