The Chicago Jack has no airstaff. Nine FM has airstaff during the morning, midday, and afternoon dayparts. Early evenings for approximately allow people chosen at random (who register at weplayanything.com) to play their favorite top 9 songs, and around 8-9pm hour is automated. Sunday - Friday night at 9pm & 8pm Saturday, it's brokered dance program Dance Factory Radio, and that goes on until 4:30am Sunday - Thursday & 5am Friday & Saturday. Originally when Nine FM started, they had airstaff in every daypart. Then around the time program director Sky Daniels left, evenings was eliminated, then overnights. Traffic reports used to take place in the morning & afternoon dayparts, but at least the afternoon traffic reports were eliminated. I don't know about mornings though, as I'm usually asleep during the early morning hours.
