Any of the Uniden or GRE/RS digital scanners will trunk them now and after Joliet changes over....However, STARCOM has a "Phase11 (using Phase1 now) that will be implemented some time in the future and the present digitals most likely will not work on it with the exception of the GRE/RS PSR800/PRO18 and they have not been tested on this upgraded system because there are none as yet upgraded to Phase11...Will Co can be heard and Joliet on most analog trunking scanners now.....
