This from a CarmaChicago conversation:

Tri-Com will probably be adding North Aurora Fire and Sugar Grove Fire and Police to their covered agencies in the coming months. (
Rumor also has it that they will be adding a second fire dispatch channel, but I don’t know what the freq or PL will be for that yet. Sugar Grove PD will take the 5 series unit designators (5-paul-x, etc) when they make the switch.
