That is because WWIQ is not a full powered FM station anymore.
Sure they got a boost in height, and that DOES help but...
WMMR is running 16,500 from One Liberty Place and WWIQ is going to be just 9,000 watts AND lower on the tower.
A Class B FM station is referenced to: 50,000 watts from 150 meters up.
WWIQ is located at 244 meters high which means they can run a maximum of 19,500 watts and be a "full power Class B".
Of course they could stay at 9,000 watts and move up to a height of 347 meters and be a "full power Class B" that way also.
Either adding 7,500 watts OR moving up another 103 meters would make them a "full power Class B" and greatly improve their coverage.
