The Pro-18 does P25 Phase II? Where did you hear that? The GRE PSR-800 is currently the only radio that will decode X2-TDMA so far. The Pro-18 has yet to be verified to decode X2-TDMA, and no Phase II TGID's are yet on line. The Pro-106/197 is P25 only as you mentioned.Pro-18 Is digital P25 works great also does P25 phase 2 pro-106 does not.
