Radio encryption in Jefferson County
Jefferson County agencies run on the Alabama Interoperable Radio System (AIRS). Five of six logged agencies are recorded as fully encrypted and one partially. The Birmingham Police Department is verified as encrypting all monitored channels using P25 ADP, while Homewood Police, Hueytown Police and a Tarrant Imterop entry are verified on P25 AES-256. The Fultondale Police Department and the partially encrypted Trussville Police Department records are unverified. The county's talkgroup counts are lopsided toward encryption: 36 of 43 monitored talkgroups are encrypted, with 7 still in the clear. A scanner in Jefferson County will therefore receive comparatively little, and none of the clear traffic can be attributed to a specific department from this record.
