This is sort of a last minute post Does anyone know what frequency activates the old 1000T in Bloomington (the one behind Lunds and Byerlys)? There’s the modern encoded Civil Defense frequency (155.055), Hennepin Fire Pager (154.385) and the Bloomington Fire Pager that I’m not sure is active or not ...

The air pressure alone near the siren would cause damage. Plugging your ears like that might help, but it won’t do too much

Every time I leave my therapy there’s a building with a vent that looks just like a Model 5 and I freak out every time

I have quite a few better ones than these, but these are the only ones I currently have access to. I’ll post more when I get home tonight

I have a Vixen Horns VXS-1000P hand crank siren and I'm so confused as to how the chopper keeps spinning after you stop spinning the crank. If you know please say because I'm totally confused :?

There’s a Model 2T on the corner of the Daytons department store in Minneapolis. You can ask them or the city. But otherwise I’m not sure. There is another model 2 in the north-west metro suburbs area that is from the early 90’s, probably not going to go for the next 20 years though
