Hi everyone, Merry Christmas. It’s been a while since I posted, but thought it worthwhile to post an update on Orland Park’s system. It appears all P10/15 sirens have been or are in the process of being replaced with FS2001-130s. The older 2001 by Centennial School appears to have also been replaced...

I was the one who used to work in that building. Signature Flight Support leased it from the City and used it as their GSE maintenance shop. There was talks even when I was there that the city was going to take the building back and redevelop the land it was on. Haven't worked there in 2 1/2 years t...

Surprised this hasn't already been posted, but great video of a rare siren nowadays.

Could this be one of Aurora, CO Whelen 3016 doing whoop? I know they have some dual tone ones and they use whoop for tornado warnings or all clear, I forget which.

I'm assuming this is the one you recorded.

This video has some great ambiance and a great view of the tornado forming. You can hear the P15 clearly and at 10:40, you can hear a 10V windup.

One in the first video is a P-15, I know that sound anywhere. Good call, I didn't even notice the rotation of the siren until you pointed that out. I just assumed it was a 10V because I looked up all the sirens in the surrounding areas and they were 10Vs, 3T22s, the Sterling M5, and a Model 2 or 5 ...

You can also hear a 3T22 in the videos.

Expect more to come. Lots of tornadoes in the Chicago area today.

I remember seeing this siren a few years back in Evansville, MN when I was still in school in North Dakota. They never had a good street view, but I checked today and alas, here's a great view. https://www.google.com/maps/@46.006005,-95.686529,3a,60y,94.12h,87.16t/data=!3m4!1e1!3m2!1sWU4weQidHHy-0hq...
