Seems pretty straightforward to me. New license WQNI211 which was applied for in December and authorized by the FCC in February. License states it's for the police dept, for a repeater on 166.250 with an input of 154.890.
Their other active license, WQDX548, is for a simplex Base/Mobile setup on 155.415, not a repeater.
Looks like they wanted to upgrade to a repeater, and did so.
What else is there to know? Figure out what PL/DPL they're using on the new repeater, then keep listening to 155.415 and see if the usage has changed, i.e. gone from the main dispatch frequency to a car-to-car or tactical frequency. Submit changes to the RR DB so that others can benefit from the info.
