Cackis...the original plan was to keep NJSP on the 800 system and upgrade it to Phase I.

Thanks signal zero. Was just curious because we all know plans tend to change lol.
It was an assumption. The audio on the troop channels kind of sounds like the patches I hear on the Burlco system. After reading what Alex had to say I know it was an incorrect assumption.
I would have not a clue if this is the plan or not. They likely have the plans to convert the sites to P25. To do that they need a lot of physical rack space, a forklift, etc. They have to replace their base stations with GTR's (if they are not already), install new site controllers, etc. They then have to realign the simulcast and possibly update their microwave / back haul circuits to support the new sites. If they in theory say have 20 channels in their north simulcast cell with 6 sites. (I'm sure i could look this up but follow the example). Those sites will need 120 new GTR stations... They won't be able to take the old stuff off the air, so they pretty much have to build an entire new site and pull the old one out. Or if they can go channel by channel.
It's not really in-expensive to do. If you guess a GTR costs about $30k/station - $3.6M in just RF equipment, not including the rest of the site equipment, labor, etc.
Not to mention the subscriber upgrades that have to take place depending on what they use today, reprogramming, etc.
Not really a small or cheap task.

Oh trust me, I'm aware of the cost for the equipment and infrastructure required. My question was more geared towards the estimated time frame. The original plan WAS to built it out to Phase I and keep NJSP on that system while others moved over to the 700 ICS (don't know if that STILL is the plan). If they did, NJSP would have have roaming capability on the ICS, could use it for a backup and interop, etc. Just seems to me that the State is pouring ALL the funds into the ICS as I haven't seen movement on the Smartzone system being upgraded and the plan for both systems was discussed simultaneously. All new subscriber units I've seen are XTL/XTS series which would point towards Phase I...the majority of cars I've seen still have Spectras...
It may seem this way simply because a lot of PSIC/UTAC/ITAC infrastructure that was built out on UASI grant money (my understanding). There also seems to be demand growing to increase capacity and coverage with local agencies who want time on the system. If towns get on board with the regional/state based systems then it's a win/win for everyone. The problem with NJ is everyone wants their own control because they have had it for years. You give it up and you give up funding you had once and can now no longer get because you do not need it. Budget for new subscribers every 5-10 years and you should be good to go.

In case anyone is trying to narrow down what radios are using the 700, it appears that radio id's 151xx through at least 152xx are on 700. I confirmed this by the radio login on the NJICS system, which started the simulcast. I have about 5 radios confirmed right now in this range.
It looks like the NJSP ODU may have taken over dispatching for Human Services Police. I see HSP Police being frequently being patched into the Marine talkgroups.
NJSP did take over the Human Services PD dispatch. We got one of their laid off dispatchers about a month ago..
Keeping the 800mhz seems like a good cost effective idea. Even though a lot of the radios are 700/800mhz compatible there are enough that are exclusively 800mhz ( older fleet radios).
Cost effective yes, but at what expense? The older the radio's get, the more likely of them breaking down. They should not cut these cost because a life (Whether it be an officer or civilian) could be at risk.
I couldn't agree more with you.
CIB 2 is in use,
Clarification on simulcasting
I understand the multiple tower simulcast setup, my question is do transmissions from the NORTH system also get "simulcasted" on CENTRAL & SOUTH. Today when traveling from my home in Sussex County to Philadelphia I wanted to monitor 2-COMM. I have both the North & Central Simulcast "Sites" setup (HP-2). Once I traveled outside the northern territory as I've seen them on the system maps I no longer received 2-COMM comms. You could see it locking onto the CC but it never found the talkgroups active.
I have cut back on the number of "sites" that Sentinal loads onto the radio by avoiding the I/R's and SOUTH as I'm rarely in that area and it just slows down the scan as it attempts to find the CC.
Any clarification would be appreciated. I viewed this whole thread and didn't find any full explanation except for the possibility of CENTRAL simulcasting SOUTH & NORTH. You would think that when a car logs into Sussex with 2-COMM and then travels down to say the Secaucus area or Sea Girt that their radios would be able to communicate as long as they are in NJ.
Thanks

The system will only pass TG'S from one site to another if a radio affiliates to it. There are no 'automatic patches' on the standard patrol channels, but it is very often that almost all Troop C patrol TG'S come across Troop B, and I'm sure it's similar for Troop C. Don't expect to hear Troop A traffic in Troop B, though.
Troop C's area has a large amount of both A & B traffic during the daytime (not often down there enough during work to truly quantify how much, but I have heard all 3 sections of the state active in C's coverage territory).
