Hey all,
I got an ambiance recording of northeast Memphis' sirens yesterday during their weekly test. I have posted the video on my main YouTube channel. It turns out that Memphis tests their electronic sirens separate from their electro-mechanical sirens. I recorded this from my grandmother's backyard. The damaged ACA P-50 on Germantown Pkwy (about 4 miles away) can also be heard (yes, the outer horn is still missing).
Enjoy!
