I haven't checked this a.m., but last night, I didn't hear one transmission by any service on the EDACS system. Also, twice, I heard this loud foghorn type sound from the system. I've heard that many times years ago on WTU's 800 system. I don't know if EDACS is/was down or not. Usually, there will be something from the city buses or a fire call. It was dead the entire time I had the scanner on. Maybe just an unusually quiet night. I don't know what the city and ProVoice gang would do if the system failed. I checked my scanner, and it was working right.
