Speaking of WACG-FM now owned by GPB Radio. Their transmitter site is actually on one of the Augusta TV towers across the river in SC so at least half the signal is over SC. Back in 2009, WACG moved to the GPB TV tower near Wrens. While it placed most of the signal inside the state of Georgia and despite maps showing city grade coverage across Augusta, they got so many signal complaints in Augusta, the signal was moved back to the TV tower. A lot of the upper income residential and commercial office areas of Augusta where GPB probably has its listener base sit down in the Savannah River valley and a FM signal tends to "ride over" the city if it is coming in from the west.
Recently GPB filed to move back to the Wrens TV tower. This time the signal will be directional to protect a FM permit near Vidalia and another permit at Lincolnton filed the same day to move closer to Augusta making both moves mutually exclusive to each other so for either to be built, the two parties will have to reach some sort of settlement or find a technical flaw in the applications to have it dismisssed.
GPB has made an effort in recent years to fill holes in their coverage area in rural areas of the state, mostly in South Georgia, recently building out new FM signals at Kingsland in extreme SE Georgia and at Bainbridge in extreme SW Georgia. They have a permit for a new station to go on their TV tower at Pelham, Once built, the largest towns in Georgia without primary signal GPB radio coverage will be Americus, Vidalia, Swainsboro and Thomasville. My guess is the Pelham signal may be further developed in the future to put more signal toward Thomasville leaving just Americus, Vidalia and Swainsboro as the key rural population areas where there is difficulty picking up GPB radio on most automobile radios and pretty much zero signal inside structures.
