I'm still hopeful for a mixed format station...one that mixes equal parts conservative, liberal and something in between. Alas, Atlanta is conservative talk country.....pipe-dream.
A station that is going to do "alternative" talk programming needs all the listeners it can find. That usually means finding space at that end of the dial on an AM station, and probably a daytimer. If these stations could reach out 40 miles or so, they might garner enough listeners-who-respond to make the venture viable. This challenge repeats itself in virtually every market in the country.
The good news for these experiments and ventures is that probably the population from Decatur to Downtown has the highest percentage of potential listeners for something other than conservative talk.
It boggles the mind to think about trying to do liberal talk on a limited coverage AM station in Cobb County... or Cherokee, Forsyth or Hall County. It's probably illegal to try in the counties at the south edge of the Metro.
