Duncan Payton’s run as PD of Clear Channel’s rhythmic WWVA-FM, which started last November, has come to an end. Dennis Martinez will get his “Groove” on as PD starting June 1. Martinez formerly programmed CBS-owned KZON-FM (101.5) in Phoenix, and prior to that, Clear Channel’s “Wild” KYLD-FM (94.9) in San Francisco. Clear Channel/Atlanta Director of Operations Scott Lindy says, “Dennis brings the experience and talent in the Rhythmic AC format that will keep 105-7 The Groove moving up in ratings and revenue.” Payton is moving to San Diego.
