Hey everyone!! It’s been a LONG time since I’ve posted on here. I’ve been out of the siren hobby for about 8-9 years now after I sold ALL of my previous siren collection. A week and a half ago I purchased and picked up the former West Lafayette, IN City Hall Thunderbolt siren from another member her...

I wonder if that's the original RCM then. I seem to remember the last two digits of the serial on the siren motor being "79" which should mean that it's a 1979 model year.

This was taken on my doorstep, with the nearest Vortex being a block away and the second one being about a half-mile away (or so). I did not record the alert cycle, but did record the attack cycle.

All sirens in Minneapolis have either already been replaced, or are going to be replaced soon (2001s and Thunderbolts mainly). They have been working on the project since l...

I probably won't get to painting until next week because I have to decorate a parade float for my weather station business for Friday night. My town of Madelia is having their annual "Parade of Lights". What better float decoration for a weather station business than a tornado siren?! I'd...

I feel like I need to reiterate what I said at the end of page two...
