Welcome to the RR forums. The system may be Phase-II CAPABLE but contain FDMA talkgroups (mode "D" in the RRDB). Can't know for sure since you didn't give us system specifics
As I predicted in post #3, talkgroups in your county are Phase-I FDMA (mode "D") although the system is Phase-II/TDMA CAPABLE. You should be able to pick them up just fine with the programming as-is. You won't be able to switch the setting unless the county converts their talkgroups to TDMA (mode "T") & the change is submitted to the RRDB
