Where I live this half of the county is totally covered. Each Wednesday at 3pm it says : “this is a test, this is a test, this is a test of the Tooele county emergency warning system”. Looks like 900 MHz feeding the system. Many times I have thought about commandeering the system to announce the return of Jesus or something.
