Radio encryption in St. Clair County
Port Huron Police and the St. Clair County Sheriff are the two agencies tracked here, both verified against RadioReference system data and both encrypting all monitored channels with P25 DES-OFB. They operate on Michigan's Public Safety Communications System (MPSCS), which remains mostly open in this county: 81 of 85 catalogued talkgroups are in the clear against 3 encrypted. Encryption is applied narrowly to the two departments above rather than across the system, so a scanner configured for MPSCS still receives the large majority of catalogued local traffic.
