Because it doesn't work. It does not bill well enough to ever support talent long term. Art's studios are old and in disrepair with turn knob boards and old computers. Small town radio can only afford low experienced talent and for some awful reason still read obits. As for community, Sky104 and WNEG still sound great. The others are just small town sound.
WCON has always sounded like you describe, when Bobby Foster leaves, her son's will fix that. WDUN is a three station juggernaught that sounds tight. Joel Williams understands how radio should sound. WCON had the hottest stick in the region, WDUN has three bases covered. Everything else is just static, or should be. There are plenty of powerful signals out of Atlanta, Athens, Greenville and Ashville to give folks something to listen to. Also to be commended for survival is Dean Dyers WRWH. Dyer understands small town radio, where WDUN takes medium market to a large market standard. WCLK holds its own. Strangly enough, every station in the region shines very bright with High School football. They all get it right. Especially WNEG, WRWH and of course WDUN. But the rest of the time the tiny stations are ag reports and obits. The programming models just reak.
Tug is not the visionary Art is and the stations suffer for it. So do the listeners. Art could take a lesson from Joel Williams, always sound bigger than you are, or you will never grow. The Jacobs have always understood that.
If you do like GaCa, you will not grow. Small and medium stations should strive to sound busy, happening and huge. Otherwise, just use network satellites, play spots and automate. Why bother working toward sounding small? Piss on it.
