Look at the listings for the OPP - Digital areas, all the analog systems listed are active and worth monitoring if you do not have/want digital.
All OPP Vehicles have a mobile repeaters, and when active transmit to the officers hand held radio in analog format. The portion of this system which is digital is the Tower to Car, and Car to Tower. Also in areas policed by OPP Beat officers, the other "Beat" towers are operational.
