These are the radio ratings for July in Sacramento. The Don G Morning show started July 11, so its tough to judge the station's ratings until that show has a few months to mature. Plus, these are ratings for adults 18+, which isn't KHTK's core demographic. They focus on Men 25-54.
Now, with all the small print taken care of, I was interested to look at the sports station's ratings in Sac. I think Don G has been PD for a couple months now, and the station's ratings have been flat during that time. Surprisingly to me, ESPN 1320 actually went down in July. So, apparently, more sports-focused fans aren't jumping ship from KHTK to ESPN 1320.
