Seven use P25 AES-256, namely the Arcadia, Cicero, Fishers, Noblesville, Sheridan and Westfield police departments plus the Hamilton County Sheriff's Office, and Hamilton Southeastern Schools is listed with MOTOTRBO. Two systems are on file, the Metropolitan Emergency Services Agency (MESA), formerly IDPS, and Indiana Project Hoosier SAFE-T. Of 89 catalogued talkgroups, 16 are encrypted and 72 are clear, so a scanner still has a good deal to receive on these systems even though the agencies above are not part of it.
