Other notes: For 1st Wednesday, I decided to hit up this T-128 near downtown Iowa City. I was able to get a decent shot with the cinema building and it provided some good echoes as well. You can hear other T-128s and Whelens after both wind downs, and after the 2nd wind down, you can hear one Whelen going for a full 3 minutes. This was directly west of here, so it might be a future target.

This particular T-128 is partially responsible for a viral TikTok from a few years ago, where someone filmed the sirens in Iowa City going off for a tornado warning, and you can hear a Whelen, this T-128, another T-128 (DC only), and an Allertronic, and it produced a very harmonious sound. The Allertronic is long gone, but you can still get a very pleasant sound in downtown from the T-128s and the Whelens. Oddly enough, this T-128 is 1 of only 3 in Iowa City with an AC rectifier. All of the other T-128s are DC only, even though they're all newer than the AC/DC ones.

Camera used: Panasonic HC-V800
