Nope. It was supposed to happen a few months ago. The only talkgroups I show are City of Miami PD/FD main channels
and Hialeah on it so far when they intra-WACN roam over. Broward subscribers did not get the new P25 systems from the south on the first touch, but there are talks that both are getting each others interops channels. Miami-Dade (county admin and PD side) are still not playing nice in the sandbox but at least the Cities are talking.
For those of you with Unication G4/G5 pagers, I took the main PD/FD talkgroups from City of Miami and put them under on "System" I created called MIA/HIA/MB P25. Basically you throw ALL frequencies in for all three systems (remember Harris can roll to any for a control channel) and then since the WACN, RFSS and Site are all the same, you create a widcard FF for the system ID, but use the correct values for the others. Then create a Trunking TG-Scan zone and assign to a knob position and add the talkgroups. Now as you drive around, you'll automatically roam to all three systems based upon where you are.
