Heather Advisory: Curtis WQDR/Raleigh part-timer Heather Davis has joined Cumulus' WKDF/Nashville in middays. She succeeds Becca Walls, who stepped down last week (CAT 5/4). Davis' prior stops include WGNA/Albany, WRNS/Greenville and AC WMSX/Buffalo. "The minute I heard Heather's audio I knew that she was the sound we need on WKDF," says OM and Cumulus VP/Country Charlie Cook. "I love her varied on-air experience and she is a social media monster, which is so important today." Adds Davis, "It's a dream come true to be living and working in the home of country music. I can't wait to experience my first CMA Music Fest and all that Nashville has to offer."
