Chicago Tornado Siren Test - Federal Signal Modulator 6024 - 7/2/2024

Yes, before you ask, this is one of the sirens that is responsible for making the creepy "alternate wail" signal associated with siren head. No, it's not broken, it's working perfectly fine.

Bucket list item done! Today I finally decided to record one of Chicago's modulators for the first Tuesday test. It wasn't anything special but it was nice to film something out in the city. It was also cool to hear a modulator on the older "MC" controls, especially with that longer wind-up. Afterwards I went on a tour around the city to visit some of the old civil defense era sirens that are still up. Got some climbing exercise in as well, do what you wish with that information.
