The Siren Board

Can't tell if its a dual tone or a single tone, but it sounds an awful lot like a 4/5 port dual tone at the front of the vid. And the fact that the user claims the siren is 2 to 3 miles away rules out that it's a 2T or anything.

Sounds like a T128/135 or Hurricane. Has no resemblance to what it sounds to me of a Thunderbolt.

Heard multiple sirens however to what it appears. Possibly a 2001 and something else I wasn't able to make out in that mixture.

Sounds like a P-50 to me. The audio quality is not that great so it's hard to tell.

The poster said it was filmed in Jefferson City, MO.

Jefferson City, MO has a system of P-15s.

sounds like there are 2 sirens & both are rotating. One is a dual tone & one is a single. The dual tone sounds like a Hurricane & the single tone is alittle far off to identify correctly, but it sounds to me like a 2001. I couldn't hear the single tone with my speakers, but heard it faintly through my sony headphones.

Almost sounds like a single tone (8-port) P-15 and a dual tone (9/12) P-15's sounds combining together to make that major tone we're hearing in the video. I don't think Jefferson City has any Hurricanes.

Could be. Maybe someone local to the area could record a higher bitrate recording that's stereo so we could distinguish between them better.
Of course if the wind is gusty, or if the siren tones are canceling each other out, sometimes it will make distant omnidirectional sirens sound like they are rotating. We had 2 distant thunderbolts and a model 5 here years ago that would do that to a nearby 2t22.

Jefferson City has 10 Penetrators, 3 2T22s, and 2 Thunderbeams.

This brings back a lot of memories.
I lived in JC mid 60's to early 80's, when they had the older high pitched(10/12?) allertors. When I left in 81 or so, they were starting to replace them because of all the rotator problems they were having.
I remember a year or so before I came to CA there was a picture in the paper of the then new 2t22 being installed on a hill above Missouri Blvd., then the "main drag" where all the fast food places were. Then, just before I left they replaced the allertor on the post office downtown with something; I don't know what it was.
One interesting thing about the JC Allertors-- on every one that I ever saw, except for the post office one, the wedge-shaped "projector" on top was installed in a verticle position. And, somehow, they were all just the tiniest bit crooked. Imagine on a clock--instead of being at 12 o'clock, being aligned with the 3 or 4 minute mark. Weird!
One last thing--where in the world are the Thunderbeams located? I don't remember any of those from when I was there.
Those allertors sounded like the ones in the recordings from Mason City, IA(I believe it was); still my all-time favorite siren sound!

Sorry about the double post above! When I clicked submit after previewing it, there was a "timed out" message, so I thought the first try didn't go through! Now I know better!
