Ben Fong-Torres, in his Radio Waves column in this morning’s Chronicle Pink Section, points out that the Arbitron ratings for radio stations leave out public broadcasters, but if they were included, KQED 88.5 would be No. 3 in the Bay Area with a 4.7 share of the audience. That would be right behind the perennial market leader, KGO (6.1), and KOIT (4.9). “The strength of KQED’s service is in-depth local and regional as well as national and international news,” says Jo Anne Wallace, vice president and general manager of KQED. (Fong-Torres also has items about a change in the morning team on KNBR 680, a way to hear Don Imus even though he isn’t carried on any local stations, and an anecdote about bandleader Del Cortney, who died Feb. 11.)
