Looks like one to me. I do know there is one on some school in SFO that's just kind of there sitting on the corner of the roof (dismounted may I mind you) for no explainable reason that I know of. Don't remember the school name. I know it was an elementary school however. The STL is located at Sunn...

All the Janesville Soundmasters are long gone. "SM Place" refers to the siren itself, not its location.

An RM-130 in Conway, Arkansas.

Wasn’t Federal and ASC notified about this when they did it the first time? If so, I’d like to see what they said. Federal Signal was contacted by a board member when the ATI Modulator drama happened in 2016. (Unsure if the response is still around, it was posted on Facebook but since I'm not logge...

Didn't expect ATI to return to a project they almost got sued for. For context, back in late 2016, ATI had plans to make the "OHPSS-32," a clone of the Modulator. Here's a thread about the drama: https://www.airraidsirens.net/forums/viewtopic.php?t=20710&hilit=ATI+modulator Is it just ...

A picture of a Thunderbolt 1003 which was installed outside of one of the Titan II Missile Silos in Arkansas. The siren fell victim to the explosion in 1980.

Wait, where in Norwood Young America? 44.78218395315515, -93.91517749667577 it was here until sometime between 2010 and 2014. Westy1962 got a video of it in 2010 and it didn't sound the best bdk4a-PmuM8 Dang. I couldn't be surprised more than this. And they discontinued Thunderbeams before this. HO...

Definitely a Hedberg. The horn on the "Mystery Siren" and the horn on Sentry95's Hedberg image are an exact match.
