Former Raiders spokesman Artie Gigantino says he expects the team will leave KSFO-AM 560 next year and move to KTRB-AM 860, which will flip to an all-sports format on Monday. KTRB already carries the A’s and has indicated an interest in East Bay sports as a way of counter-programming KNBR-AM 680, which carries the Giants and 49ers. “It is very obvious to me that this move is inevitable,” he says in his Examiner column.
