Were it my company, I'd make some pretty radical changes:
1. Local managers would have local program directors putting together the music lineup for each station. No more of this corporate one-size-fits-all garbage.
2. All local DJ's from 5am - 7pm at least. They would be encouraged to intreact with listeners on the air. (not live, you could tape it for safety) Some stations still do this, but most don't.
3. Local news at top and bottom of each hour, on each station, 24/7. We're talking 2 and 1 minute cut-ins along with a little weather and traffic and a commercial avail.
4. No more than 4 commercial breaks in a hour and no more than 3 minutes of commercials in each break.
