Update
As of right now the PD dispatchers and FD dispatchers have NOT moved into the new combined dispatch center. Building still being worked on, but some of the command staff are in the building.
All PD and FD vehicles have new radios installed but are being used on old conventional system right now. PD special units have had their new radios issued to them but the uniform patrol units have NOT been issued new portables yet. Some of the PD special units are reporting that they can use the system outside the city a lot better then old system.
It appears from monitoring the system (pro96com) that radios that ID with 100000 number belong to PD, 200000 belong to FD, 300000 belong to possibly DPW, and 400000 belong to Jersey City Incinerator Authority.
Some of the new unconfirmed talkgroups are 3001, 3004, 3008, 3009, 4003
From hear only a couple of transmissions of the 3001 talkgroup I would say that it probably going to be one of the DPW talkgroups.
When I know more I will update.
