KNEW 910 used to be CNET, I think - a business- and technology-oriented station, which was a pretty neat station. I think they played standards before that. Anyway, 910 has some good programming now.
I heard him on the dial yesterday. My radio was a cheap analog, so I can't say the frequency precisely, but it was greater than the 610 oldies station and less than 680 KNBR.
