It is only a matter of time before they do just shut this frequency down. Radio alone is slowly dying, let alone AM radio at that, with the Boomers dying off and Gen X getting older. The newer generations and even Gen X mostly listens to everything online or either iTunes or Amazon.
Yes this may be true, but just imagine if there's a large scale internet outage, there's a solid chance that this generation may discover radio, during the most critical time. There's still hope and by the way Amazon, iTunes and Spotify or any music streaming service won't tell you when there's an emergency.
There's a few cities in Wisconsin like the city where I grew up where the Tornado Sirens were out of service for years, they desperately needed a referendum and folks said NO!.
As a side note: Radio still has a future especially in the north woods of Wisconsin - in those areas I doubt that Radio will die anytime soon.
In my area where I grew up no such thing as Cellular Reception, so us folks actually grow up listening to radio, keep in mind this was in the late 2000s. In my childhood town we just got 4G in our area, 5G is probably years away.
My point, in cities that are NOT in the deep north woods, absolutely Radio will become a dying art, but for those in the deep north woods, Radio will most likely remain as the absolute most reliable form of getting Music, Weather and News, unless you have a 199 foot pole or live at the top of the hill good luck, Radio will be hear to stay.
