I wish there was a way to have an SDR monitor and record every EAS event (tests and alerts), across the bands....every AM, every FM, every TV and NOAA.... in the market.
That would be interesting.
Stations can opt-out of most alerts. They can be a "non-participating", only having to go off the air in a national emergency. They still have to run the tests.
I sometimes wish the local damaged-freight store had a pallet-load of cheap radios and TV sets. I might set one on every channel, and watch.
The big problem here is, the SLC market is huge. A weather alert (etc) may not affect people in much of the market. Different regions have their own radio stations, but not everyone is listening. Many are listening to translators, and most TV viewers are watching the big city stations, or no "stations" at all. Getting an alert out to the OTA, satellite and Cable TV viewers requires it coming from SLC stations. The counties and small towns can activate their local area, but it would usually only go out on the local radio stations.
People in the south don't care for snow warnings, and people in the north don't care about the south's flash flood watch. There needs to be an addressable system, that can't be defeated, but can be made more palatable. Phones aren't the answer, because we find that many people disable their phone's alerts, or never set them up properly. Too many local governments buy alerting software, like "reverse 9-1-1", but everyone has to subscribe and load provider-specific apps.
The Emergency Alert System really should be a universal, reliable tool for everyone. It needs to be taken seriously.
