I'm not an engineer, but I wonder has Cox's engineering team ever given any thought to moving the AM 750 transmitter out of the strip shopping center across from Northlake to a marshy or swampy area somewhere in the general vicinity that would be a lot more conducive for the ground conductivity that a 50K watt AM signal needs.
This is not about coverage, it's about the age of listeners and sales.
With the right ground conductivity, WSB's daytime ground signal could easily cover a 250 - 300 mile radius much like WGN in Chicago, or WLW in Cincinnati does now.
The conductiviy of N. Ga. is terrible. No matter how damp the site itself is, the ground conductivity, like that around WSM, will not permit the same kind of coverage that a station like WGN gets in the high conductivity area that surrounds it.
WSB's nighttime signal isn't an issue, considering that it covers 38 states and parts of Canada.
Most AM listening is in the daytime hours, and most ad sales are in that time period. And with the interference on 750, and the protection now in effect, the reliable skywave coverage is perhaps 400-500 miles around. Of course, the 100 kw station in Venezuela does not help, nor does all the junk on 740 from the Caribbean, Mexico, etc.
Since radio is bought locally, the local Atlanta metro is what matters. There is really no significant revenue to be gotten from outside that area.
