Aside from Giant games, I used to listen to ESPN 101.7 for 2-3 hours a day. When it was yanked for a year to play all-the-hits Top 40 music, I missed reliable updates, thoughtful banter, and the additional Saturday/Sunday non-Giant national MLB broadcasts. When sports returned as FOX 101.7, it was great to have Giant games back in stereo, but the rest of the programming is just awful. I suppose I am not into the shrill hosts with oddball nicknames, lewd references to female anatomy, excessive blathering about football 23 hours a day, and the lack of score updates.
During the day, I usually tune into scratchy KNBR. After dark, San Diego 1090 XX comes in nice and strong. When I need a sports fix, that's where I turn.
Have no idea on ratings. I have seen a few new billboards around town, just in time for the returning masses of college folks, who probably crave the faux 'tude that Fox markets.
