The new, less-useful KFWB that debuts Sept. 8 as "News Talk 980" will start with an 18-hour marathon of Dr. Laura — most of that reruns. Still undecided is who will fill the local talk bloc from 3 p.m. to 6 p.m. weekdays, but Register radio columnist Gary Lycan says it may not be a local at all. The frontrunner, he says, is former San Diego mayor Roger Hedgecock, who made the switch to AM radio shouting years ago and is on the air in San Diego during the same hours. Lycan also has a list of departing and remaining KFWB news staffers based on a post at LA Radio.com.
