The only frequencies that are assigned to Southern Company that I've heard anything usable on is WQBM372. It is a 5 freq l t r system at Farley Nuc plant. Years ago when skip was running I could hear them good, have not had any time to listen much lately. They are in the river valley and are weak here in Taylor. Just checked 3 freqs are tx every ten seconds too weak to decode.
