3 public safety agencies in San Joaquin County, California have encrypted their radio communications.
Radio encryption in San Joaquin County
Only three agencies are on record in San Joaquin County. The San Joaquin Sheriff is verified as encrypting all monitored channels with P25 DES-OFB; Manteca Police also use DES-OFB but on specific channels only, and Tracy Police encrypt specific channels with P25 AES-256. Both of those latter records are unverified. Four systems appear in the county data: the California Radio Interoperable System (CRIS), Fisher Wireless TeamTalk, The Radio Guys and a Lawrence Livermore National Laboratory system. Encryption barely registers at the talkgroup level, with just one of 13 catalogued talkgroups encrypted and 12 in the clear, so a scanner still picks up nearly all of what this dataset monitors.
