Chicago PD helicopter freq

Does anyone know what are the frequencies used for the CPD helicopter (air-to-dispatch/car) while in use on top of local ATC/advisory frequencies?

Primary is Citywide 1, and they switch to the Zone in the area they're operating within. PH-1 or PH-2 is the radio signature.

Thank you, I’ll keep an eye out next time they’re flying around.
