A big shakeup is coming to KGO radio: Many of its most recognizable voices are being let go as the station, which can be heard up and down the West Coast, switches to "all-news" format from 2 p.m. to midnight starting Monday.

"What we are doing is adding a tremendous amount of news content to KGO," Paul Hosley, the station's news and program director, told us late Thursday shortly after the staff was notified of the changes.
