The trustees of a small Seventh-Day Adventist college just outside Washington, D.C., took its noncommercial FM station off the market yesterday, giving up, at least for now, expanding its thin endowment by some $20 million that American Public Media offered for WGTS. “The Lord performed a miracle today and we give him all the praise and thanks for what happened,” says John Konrad, g.m., in announcements on the station and its website. The college didn’t explain the board’s decision or say whether the decision was final. Konrad said the sale was off “for now.” If APM bought 91.9, its format was expected to leap from “family-friendly” Christian rock music to secular news/talk. Columbia Union College said in July APM would be the only bidder considered, but a spokesman said last week that a bid from the parent of K-Love, a big Christian radio net, was also in hand.
