Washington - The Washington Post is pulling the plug on its Washington Post Radio project with station owner Bonneville International. The Post has provided news and talk programming for two of Bonneville's stations, 107.7 FM and 1500 AM, since March 2006. The stations also have aired syndicated programming and Washington Nationals baseball games. “The station had a strong core of loyal listeners, but it was not showing the pace of growth that we and Bonneville had hoped to see," said Post president Steve Hills.
