CPD is EDACS Provoice and cannot be monitored with any scanner, but they are not encrypted. The city is exploring options for a new radio system.
MCSO uses a UHF LTR Passport trunking system. You can monitor it conventionally by programming the frequencies listed on this site, although by using this method it's difficult to follow conversations. There are no scanners that track LTR Passport. One option that I haven't had time to explore yet is LTRTrunk. You can do a search on this site for more information on it.
