Radio encryption in Ottawa County
Four agencies are on record in Ottawa County, all of them on Michigan's Public Safety Communications System (MPSCS). Grand Haven City Police and an Ottawa County Interoperability entry encrypt all monitored channels with P25 ADP; the Ottawa County Sheriff encrypts specific channels with ADP, and Grand Valley State University encrypts its dispatch traffic with P25 AES-256. The sheriff's record is the one unverified entry of the four. Twenty-seven of 41 catalogued talkgroups remain in the clear against 14 encrypted, so a scanner covers most of the county's monitored channels, with the closed ones concentrated in municipal police and campus dispatch.
