Maybe this one was programmed to fast wail or something...

I believe that this recording is actually an ATI in San Francisco, which are programmed to sound a recording made from one of their old STL-10s. The real STL-10 sounds exactly like this from a distance. I was in San Francisco yesterday. It was sad to see all the STL-10's gone and replaced by ATI speakers, which apparently cannot be heard from many places. The Ferry Building, which once hosted the world-famous Heath Siren, now has eight ATI speakers. Two point north, two point south, four point west, and none point east (sorry, Oakland!).Whelen Rules wrote:Here is an STL-10 http://www.airraidsirens.com/mp3/airraid101.mp3
These are my favorite federal sirens ever made.
