Someone earlier mentioned getting a translator to pair with the AM. That would be the only hope for this facility but the 2 millivolt contour for a 2500 watt station is not very large - the translator would provide coverage similar to a LPFM - 5-6 miles, at best. But that would cover much of Decatur so you could super-serve that suburban city with [insert viable format here]
There are many translators that have the full 250 watts at over 1000 feet. Coverage good out 15 to 16 miles. Of course, it must meet the spacing and channel issues of any facility, which is hard in a crowded metro.
