Well, I'll say it again. Why drive all the 18-34 listeners away from 95.7 on January 1? Then on January 10 or some other future date, you hope they'll come back to 96.5? I have never heard of a radio owner blowing up a format on one station, then a few weeks later putting it on another station. I've heard of moving a format from one station to another immediately, especially if the two signals are not equal. But then listeners are told repeatedly to switch their radio dials. Usually both stations simulcast for a while as listeners get used to the new dial position.
Maybe you move an older-skewing format to a lesser signal you own and relaunch the better signal with something you think will get better demos and make more money. But both 95.7 and 96.5 are on the same tower in Missouri City. They're both at 1919 feet above average terrain. 95.7 is at 95,000 watts, 96.5 at 97,000 watts, with virtually the same coverage of the market. There is no reason to want all the car radios, office radios and store radios to have to find another Top 40 station on Jan. 1 when KKHH switches to adult hits. Then you hope days or weeks later all those 18-34 listeners will find their way to a new Top 40 station on 96.5.
