The Siren Board

This is a pretty awsome video!!! the 2001s actually sound pretty erie. http://www.youtube.com/watch?v=F0m1BN4ZmAQ

Very good. It sounds as if there are Whelens in there, too.

that was very errie but awsome great that some one caught the beging and end of the sirens.

No, the city of Chigago has no Whelens whatsoever. They do however have some single toned Modulators.

I know exactly where that was filmed. The nearest 2001 is at the corner of erie and la salle. Its right by my work. I was trying to figure out if i heard a mod, the nearest one I can think of is navy pier. That was sept 22. The only time this system has been used. So not only is it a cool recording, its history. That was one messed up night for weather

Very interesting. They had never been blowed before that day? Isn't their a mod mounted just a few hundred feet from the stands at Wrigley Field?

Wow...that is erie...the attack signal helps with the erieness....its awesome he can hear them so clear on the 47th floor!

I gotta' admit.

That 2001 and others did a HELL of a job.

Very eerie.

Also, I can't hear any Modulator, just 2001s.

That was the first time the system was actually used since it was installed in the late 90's. Testing is another story. They do a silent test every monday morning at around 7 AM. The siren head rotates about a half turn for this test. I have seen it done a couple times. Then they do the usual first tuesday of the month test with the rest of the state. That is a 30 second test using the steady alert signal. As for the mod at Wrigley, thats my siren! Its a few blocks from my house and is pretty loud I must say. Its actually mounted on a wooden pole across the street from the ballpark. I pass it almost every day going to work. The only thing that I didnt like about that tornado warning sept 22, was they didnt really use the modulators. Yes, they did go off in attack, but they did not use voice at all. The city didnt seem to care when contacted either. Im not going to say anything bad about the political party in the city like some people have done, that has nothing to do with it. The problem is "too many hands in the jar." First the Fire Department controlled the sirens, then the 911 center, now the office of emergency management. Nobody really seems to know all the proper protocols. Plus, that tornado warning only really covered downtown and the north side. Yet, the city set off 111 of the 112 sirens, one was being relocated at the time and had not yet been reinstalled.

Damn that is really freaky. It sounds freakier than that video of the lightning in Springfield Illinois with the Thunderbolts going.
