FS STL-10, Short Alert, Green Bay, WI

Ive had my eye on this old STL-10 for a while now. I saw it once when we parked nearby for a Packer game. It was hard to find a recording spot for this one but I think it turned out very nicely. It also packed a punch closeby and is very impressive for its age.

awesome! the city I live in (Buffalo, NY) has a bunch of these old guys rotting away on poles, sadly theyre all inactive except for the few that are at FDs. I even have a rare square horned one only 7 mins away from me!

This STL-10 kinda sounds like one of those European Air Raid Sirens
