A little update, 5 of the P-15s have been replaced with T-128s, so now there are 23 P-15s remaining owned by Exelon, plus the 2 city owned ones in Davis Junction.

I've finally started on my quest to record all the remaining 23 P-15s in the Byron Exelon system. I got 7 of them yesterday, all single tone, and they all sounded pretty good. The first video is the full video I got in person and the other 6 are audios with pictures added. The full video didn't turn...

I finally went through and transferred almdoc's map to Google, so if anyone wants the full system for their map, click the link below.

Just found another E Class at I believe the entrance to a girl scouts camp northeast of Byron. I think that T-135 picture I posted was the one you were thinking of as I know I have the locations of sirens 1-48. Just missing the exact location of the White Pine E Class and another siren towards the s...

Still not seeing the one on 2. Also, I trust you that there's an E Class in White Pines Park, but I can't find it in Google Earth. And there's one more after that I'm missing somewhere towards the southern end of the system.
