Montcalm County: 2 agencies with partial encryption
2 public safety agencies in Montcalm County, Michigan have encrypted their radio communications.
Radio encryption in Montcalm County
Neither of Montcalm County's two logged agencies is fully encrypted. Greenville Police, verified, and the Montcalm County Sheriff, unverified, are each recorded as encrypting tactical channels only, using P25 DES-OFB on Michigan's Public Safety Communications System (MPSCS). Of five monitored talkgroups, three are encrypted and two are in the clear. That means routine dispatch traffic may still be receivable in this county even though tactical channels are not — a meaningfully different situation from counties where all channels are encrypted. With only five talkgroups tracked and one of two agency records unverified, verify the current MPSCS listing on RadioReference.
