Many Houston stations have been VTing for a while now. Did they fool us? Sometimes they did. If you want to be sure - "Is it live, or is it Memorex" listen for the following: the EXACT time (not a few minutes after 12), the EXACT temperature, traffic reports, some news sprinkled in for good measure, and you usually will have yourself a live show.
Exactly when did Houston radio start taking a nose dive? In my opinion, when they got rid of Barry Kaye. Then the morning show fiascos started, and all the GOOD real talent started to disappear. Now don't get me wrong. There is still some talent at Cox and KHITS. Dan Gallo is a man of many talents, working 97.1 Country Legends dive time, then running to voice-track the morning/afternoon show. I'd rather listen to him VT than any other person I know. The jocks that have been at it for a while can do it in their sleep, and it sounds live.
As for Pam Kelly, it just isn't there. No talent, no timing, no nothing. They should have gotten rid of her and let Paul Christie VT (if he would, I am not sure that he would do that). We'd all be better off in the long run.
As far as Kevin Charles, he is good - but I would rather have seen they give that live spot to Dan Gallo.
Just my personal opinion - as an avid radiophile who tried to be a DJ in the 70's - and gave up after one audition tape.
