Drjtbc
I was looking through the original plans from 2005, which stated that the DRJTBC was going to go to:
"Upgrade or Replacement of Two-Way Radio System
–APCO P25 Compliant VHF Digital System
–Interoperability with NJ and PA Police (800 MHz)"
I am thinking maybe they decided to just go with the 800 MHz using the NJSP trunk system.
Meanwhile, I have been monitoring the new Delaware River Joint Toll Bridge talkgroups (which are all digital) on the NJ State Trunk Central System for a while now. Here is what I have to date:
TG41104: I hear the "New Hope", "New Hope Toll", "New Hope Lambertville", "Washington Crossing", and "Calhoun Street" bridges using this TG routinely. Most comms are to announce they are on patrol and for roll calls. Some of these bridges have guard shacks on both sides of the river, and the officers announce themselves as such, like "New Hope" and "New Hope Lambertville".
TG41136: There are several affiliations with this TG by Bridge radios but I have not heard any comms.
TG41200: I hear what appears to always be maintenance related comms, such as 'check the lights', 'move the cones', 'let them through', etc..
TG41424: There are a lot of affiliations with this TG by Bridge radios but I have not heard any comms.
TG41296: There are several affiliations with this TG by Bridge radios but I have not heard any comms.
TG41360: There are several affiliations with this TG by Bridge radios but I have not heard any comms.
For reference, here are the districts and their bridges for the DRJTBC:
District 1:
Morrisville-Trenton Toll Bridge (Rt 1)
Lower Trenton Free Bridge
Calhoun Street Free Bridge
Scudders Fall Free Bridge (I-95)
Washington Crossing Free Bridge
New Hope-Lambertville Free Bridge
New Hope-Lambertville Toll Bridge (Rt 202)
Centre Bridge-Stockton Free Bridge
Lumberville-Raven Rock Pedestrian Free Bridge
District 2:
Uhlerstown-Frenchtown Free Bridge
Upper Black Eddy-Milford Free Bridge
Riegelsville Free Bridge
I-78 Toll Bridge (I-78)
Easton-Phillipsburg Northampton Street Free Bridge
Easton-Phillipsburg Toll Bridge (Rt 22)
Riverton-Belvidere Free Bridge
District 3:
Portland-Columbia Toll Bridge
Portland-Columbia Pedestrian Free Bridge
Delaware Water Gap Toll Bridge (I-80)
I am not hearing any comms on the previously used 156.120, 156.135, or 156.225 repeaters, so they may have completed their change-over to the NJ trunk system
