CBS Radio KTWV-Los Angeles The Wave has promoted APD Ralph Stewart to PD. He will continue to serve as OM of Adult Hits sister JACK FM. An in-house memo from CBS/LA SVP/Market Manager Dan Kearney to the staff that read: “For nearly 13 years, beginning in 1990, he served as the station’s APD, playing a major role in the sound and music on The Wave. Ralph’s passion, vision and understanding of The Wave’s brand, plus his track record of success as part of the team that helped keep KTWV in the top five for over a decade make him a perfect choice for PD. The Wave is a brand that has always been rooted in quality and we are looking forward to Ralph maintaining the station’s high standards while injecting some fresh ideas into this Southern California original.”
