Last year I recorded the Kansas Statewide Tornado Drill in Blue Rapids, KS. They have a lovely mix of 2 2t22s and 2 Allertors. One of the Allertors may not be functioning. There is some high pitched siren that I searched high and low for in town and could not locate. Could it be one of the 2t22s with a blocked intake??

Blue Rapids sounds their sirens in a custom on/off cycle for tornado warnings and alert signal for fire calls.

I'd be worried if a 2T22 with a blocked intake would sound that high pitched!

It could be a single phase 16 port siren or even an electronic of some kind as it's right on 850Hz. Still a very creepy ambience nonetheless.

I wonder if one of the Allertors have been replaced by a Mod. Possible but unlikely.
