I don't care what anyone says. Stations like that are NOT operating in the public's best interest (or in their interest at all) and should be forced off the air. Even if they (only) came on during severe weather, people would still have to know that they are there. Which doesn't seem likely.
They don't come on for severe weather; they just come on to be able to say they are meeting an FCC requirement to keep the license alive.
It's likely not coincidental that this station went silent at the start of the recession. It is likely that what was a marginal station became unprofitable and could not find a buyer. At some point, they should surrender the license, but with no new AM daytimers being granted, that means that the community will never have another local service of that kind.
