I would suspect for their current formats, 104.7 (especially) and 106.7 are perfect signals. 106.7’s 60dbu makes it a bit further out, to Peachtree City, Kennesaw, and Douglasville. What would be massive would be a 105.3/106.7 simulcast or 104.1/104.7 - sure it’d be a ton of wasted signal, it’ll never happen, but talk about a couple interchangeable pairings that could make it easily from one end of the state to the other!
Actually…Cox does have a simulcast in Houston on two class C signals that are slightly deficient in a small part of the market that could fly on their own but they simulcast to have complete coverage of every inch, 106.9/107.5 The Eagle.
