That begs the question...is anyone going to rebuild a 1,600' stick if it doesn't put a city grade signal over Atlanta?
Yes, they will definitely rebuild it. The South Metro is a very important center of population to them.
When they moved to that tower amid great fanfare in the late 90's, they hoped to be competitive in Atlanta, which of course they are not. When Radio Training Network purchased WVFJ in 2011, the station became "listener supported," but like the stations below 92.1, they also sell commercials (30's only).
Around 10 years ago, WALR (Kiss 104.1) received a CP to move from LaGrange to the 107.9 site in Tyrone at decreased power. The new signal would be stronger over Atlanta but smaller overall. I don't know the relationship between the two frequencies, but somehow that move would have given WVFJ the ability to increase power. They obtained a CP to increase power as soon as WALR moved. Again, WVFJ was drooling at the thought of becoming competitive in Atlanta.
Some of my facts might not be 100% correct, but this is how I understand what happened: Cox/Atlanta engineering was against the WALR move, which was the brainstorm of a Cox corporate employee whose job was to improve facilities (wisely IMHO because it would have likely decreased the value of the station). Cox started coming up with excuses to the FCC on why the move wasn't being made.
After a designated amount of time (perhaps 3 years), WVFJ petitioned the FCC to allow them to implement the power increase, saying WALR was at fault. The FCC agreed with WVFJ, and the station increased its power, still not making the station viable over most of Atlanta. The FCC told WALR that it would have to decrease wattage from 100,000 to 60,000 watts to accommodate the WVFJ power increase. In order to stay at 100KW, WALR had to move to a new site, losing significant height. The signal still does well in Atlanta but has some issues east of the city.
