As the article said, there was limited local communion. No way someone in California or Nashville could have accurate information. Supposedly the EAS should allow the local authorities to take over station but that rarely happens. No Internet data, no phone, no cell service so I believe it would be difficult to get info to KLove ( or any other satellite service so they could send it to the satellite and activate the local receiver even if the transmitter is working. Canton was lucky in that someone with knowledge was "in town" and they could hook up a generator and start emergency programming instead and of waiting for day for someone to get over closed I40.
I dealt with local emergency authorities twenty + years ago and you would be surprised how many county emergency services centers back then don't even have pages in their manuals on accessing local radio, and cable systems. Even now not everyone has thier Facebook account on 24 / 7.
The National Weather Service (Atlanta Office) does a good job with cell phone and traditional media notifications but too many rural countries are not good at notifying folks of non weather emergencies. Reverse 911 is the exception rather than then norm in a lot of rural areas.
BTW my former employer had reverse 911 capable switches as an option but some of the smaller phone companies would not spend the money. Voice over Internet puts and extra layer of difficulty for any 911 center to keep everyone accessible.
