Soundoff, thank you for posting this, and the convenient link. Nice job!
This was taken two days after the August 25th Yantai City annual test.
The main, even bigger, siren, which was pushed up on a pole out of the below ground military bunker atop Yantai Mountain, which I snuck up to record, did not sound.
But we heard the one shown almost directly west.
We could hear but not find it.
I zoomed in at the sound but could not see it in the viewfinder.
Only when we got to my wife's parent's apartment and watched the video on TV could we make it out.
Two days later we rode bicycles to this building, and after climbing four different stairways to the top floor, finally found a hatch in the ceiling.
My wife footed a metal piece I found which served as a ladder and I quietly snuck up to the roof. (Do they serve fresh vegetable in China prison?)
Motor plate reads 50 Hz, 380 V.
In my hurry to get out of there, I failed to count ports. (Must be 10 port if 500 Hz tone at 50Hz)
When I find the DV tape, I'll listen to the pitch.
(A magnet somewhere cleverly draws the rotor to park with vanes blocking ports!)
Assuming my e-mails were monitored while in China, my wife forbade my sending this from China.
Even now, the Chinese Government could deny a visa to allow me to visit.
On the other hand, they may (should) be proud of their sirens and if knowing
I own a Federal Signal 2t22A air raid siren and am NOT an American Imperialist Spy!,
may allow me to return......Please!
