Radio encryption in Gwinnett County
Nothing cataloged in Gwinnett County remains in the clear. All six talkgroups recorded on the Gwinnett County Public Safety system are encrypted, and all eight agencies in the county record — the Gwinnett County Sheriff, Gwinnett County Fire, the Duluth police and fire departments, Lawrenceville Police, Norcross Police, Georgia Gwinnett College and Lawrenceville Public Works — are listed as encrypting all monitored channels using P25 ADP. For a scanner buyer that is about as unfavorable as this data gets: no partially encrypted agency appears, and no clear channel is documented as a fallback. Five of the eight agency records are unverified against RadioReference, so the per-agency listings are worth double-checking, though the talkgroup figures come from the system catalog itself.
