Isn't there some custom ATI installation in San Francisco at the Ferry Building? There's a Thunderbolt there too.

Wow, those don't sound nearly as bad as the ATIs where I live.

My community used to use attack on their ATIs for tornadoes. It would wind up to about 825Hz, stop for about a quarter of a second, jump to about 875Hz, then wind down, then there is a pause between each individual wail. Sounds weird, huh? I'm not surprised with the low quality of their ATIs. People...

I just wondered, does anyone know basic specs (Ht., wt., tone pitches, etc.) for these two Federals?

Just posting since this has to do with testing. My hometown got some ATI HPSS32s in '04 and said they'd test them on the first Wednesday of each month with the WMC cycle. Well, I only heard the chime twice in '04, then an alert signal sometime in '06, and since those three tests, the sirens haven't ...

Looks like the same position to me...

Are there any 1000s or 2t22s still standing or are they all gone?

Also, another interesting find on Google Maps...Stroud has an ACA P-10 or P-20 on what appears to be a tower for a Chrysler.

Was this siren part of an old Tulsa CD system? Just wondering, cause there is an old fallout shelter not even a mile away.

Oh yeah, I forgot to say that that's in Tulsa.
