Every first of the month I’ve always laid out a recorder outside to capture Jasper’s routine siren test. While most tests have been uneventful, this hasn’t stopped oddities from popping up. In this one, you can hear that the DSA run alert for a bit. While common everywhere, this is super rare to hear in Jasper. In recent years the city has also been doing a lot more full-cycle tests. This is a pretty nice endurance check for the system while also revealing some programming bugs.
For some reason, one (or more) of the 2001s stop sounding at two minutes. It’s hard to tell in the video, but in Audition’s spectrum analyzer, you can see the moment when a siren or two shuts off. These appear to be the 2001-DCs that still run alert. The DSA also goes on a little longer than three minutes which is why I think the city sent a cancellation tone. They probably thought it wouldn’t shut off. However this backfired and caused it to run alert instead until they sent the cancellation tone again. Since there’s many events downtown, I thought they were just testing a new way to sound the DSA by itself but when I compared both tones they were exactly the same. A similar issue popped up a few months back as well. I do have an old recording where it sounded like you can hear it run alert in a distant ambience, but always thought it was just a fluke. What an interesting problem…
Sirens in Jasper are tested every first day of the month, promptly at 4pm They are controlled by the city police while other sirens in the county are tested at 6pm by the county’s dispatch center. Sometimes tests get pushed back a few days when severe weather is expected.

That illustration of the siren placement and movement is so cool.
Cool I'm used to sirens since 2021 and I'm used to loud things but this one was a great one
excellent!!
Tell me why I thought that was a Whelen 2000-R in the thumbnail 😂.
Great ambience! The audio sounds very spatial. If you turn your volume up loud enough with headphones it feels like you’re there in real life
I honestly don't blame you for thinking that. They look pretty similar.
Killer ambience!
It's been a couple of years since you've done a jasper Indiana siren video. But I must admit, this video is awesome.
I love the ambience in your hometown! Maybe someday you can do an Elizabethtown, KY siren ambience. Which has ASC T-128's, 2001's & Whelen's
Hearing that ambiance reminds me of some of your early tornado warning videos
Winds down the B E E P
You should come to Selmer TN and recorded this. Every Wednesday at 12:00 PM they test the sirens
What do you use to make the awesome animated maps?
Is there a google form for the Indiana siren map. I found a siren that's not on that siren map.
That MCP DSA4X4 tho
I like how you only put the audio
Do the white spinny things on the map indicate the rotation? And is the rotation on the map exact?
All sirens for the test, then a lonesome one to sound off the "All Clear" signal? how sad 😭
can you do tornado sirens in south Dakota

kiddies gonna think that DSA is a Whelen WS2000R 💀
I mean the only reason why is because the way the dsa's are separated
