I've been there. The transmitter was supposedly fixed by a guy from Jackson - but it went down almost immediately. Paid in cash - what are you going to do? Waste of $500.
The transmitter is housed with the FM there, owned by EMF (I believe). EMF allows (because of former owner of the FM) the AM to be housed in the office building. New owner will have to have a tower and new location for it (unless lease is worked out with EMF, but the current land is not very good place for tower).
The last time the transmitter was on - when the engineer patched it and left - it was bleeding over into the FM signal. But since it went down again on it's own, it was never, to my knowledge, turned on again.
True it's a poor area, but it supported it's FM country station well enough - compared to other small market radio - so sales are there.
Worth $10,000 for a fun little station that could earn a few thousand a month, but not much more.
It will absolutely NEED new transmitter (don't let anyone tell you they can fix it), New tower, and new studio. (Unless, as stated above, EMF allows to continue operating out of the building).
Good luck -
