Last week TV stations in Portland, Ore., including Oregon pubcasting stations, decided to transition to DTV on the original date of Feb. 17. Now they’ve decided to continue analog signals until June 12. “I kind of feel like Lucy and Charlie Brown and the football,” said Steve Bass, chief executive of Oregon Public Broadcasting. Broadcasting in both digital and analog is more expensive, Bass said, but OPB didn’t want to be the only metro-area station to make the conversion this month.
