Tempe Fire will be heard in the clear, usually on A7 for fire and hazmat calls, and on K7 for most EMS calls. Major EMS calls and mountain rescues would be on K10, K11, or K12.
They also have their own E2-E5 talkgroups. E2 and E3 will be in the clear for special events, training, etc., and E4 and E5 will be encrypted. Other D-, E-, and F-decks will be fully encrypted, for investigators, paramedic-to-hospital, admin, etc.
