<p>ASHEVILLE - Talk radio took a hit Friday in Asheville, as WISE/AM-1310 made a dramatic format change, dropping all of its chat and call-in programs and switching to an all-sports lineup, the first of its kind in this region. The change leaves Asheville with just one talk-show radio station, WWNC/AM- 570, which was competing with WISE for the same listening audience. In the end, there just weren't enough advertising dollars to support two talk-radio stations in town, said Bruce Law, general manager of Saga Communications, the station that operates and is buying WISE.</p>
