158.835 no longer works.
Does anyone know if they changed PD to a trunk, or went digital?

Roselle Park change to digital?

Yes they are on NJICS operating in P25 Phase 2 digital. Good thing is they are operating in the clear. If you wish to still monitor them I suggest purchasing a Phase 2 acceptable scanner so you can still monitor their digitalized transmissions.

Wow. Pretty fancy for a one square mile town with 6 patrols per shift max and a detective. SMH
Do you have the numbers?

Ahh yes I am mistaken. Been a long day!!! Anywho I have no idea what has happened to Roselle Park. Has anyone checked to see if their repeater is still on?

Listened for a half hour straight. Crickets all the way.
Next thing I always do ( if you want to pursue this) is check the FCC license database to see if they have a new license issued for a different frequency or such. If that turns up negative, run DSD on their conventional VHF channel to see if their is DMR emissions and color codes that pop up. If so, that will give you the answer that they switched to DMR with or without encryption. If they switched to P25 in a scanner it should pop up the NAC code as long as you have a modern scanner and its setup to do wild cards and not lock onto a certain PL tone code that their using.
Simple way though is run DSD from a tapped scanner to check that. Also monitor the NJICS talkgroup and forum pertaining to it to make sure people didn't get hits from a new talkgroup that's theirs.

Woah way too technical for me John. Lol
The one thing I do know is that the FCC license for 158.835 was renewed in 2011 and good through 2020.
Yes I did check that and saw that too for you, however even though their license is still good doesn't mean their using it conventionally like the way you've been listening to it. They may have another license issued to operate it in a different way ( DMR) or they got approval to use NJICS in testing, etc etc. Another easy way to find out is simply ask the RR community. I myself don't know off hand what happened to them nor do I actively monitor them at any given time. I'll try to dig a little bit for you like look to see if it was mentioned in the past few council meetings in their minutes approved or check the FCC database for you.
Took the time to check the FCC database for you and didn't turn up anything unusual. Below I will post ( hopefully it works too) the web address for the FCC database with a broad search of all licenses that are currently active within Roselle Park, Borough.

Frequency in use this morning. Normal operations. Remember, RP is a small town with not a whole heck of a lot going on. And as I discovered early on they make use of MDTs for communication purposes.

Yeah, Roselle Park is working just fine on 158.835. Keep in mind there have been times they switch to their secondary frequency as their main dispatch whenever they have a problem with their repeater. I would not be surprised if RP switches to NJICS in the future, since they have been seeking a new system for quite some time, but got rejected (for good reason) by the FCC in the past.
For good reason? Why?

The town is 2 square miles, that's why. They don't need a mega Trunked System. The FCC rejected their previous Trunked requests because the town is too small, therefore not needed.

If there was a rejection, it more than likely happened during frequency coordination. A system has to have what's called channel loading (the FCC will return a license application for that, on certain frequencies, but the coordinators or regional planning committees usually catch it first). That is, a certain number of mobile radios need to be on the system. In some frequency bands, or to satisfy some regional plans, an applicant cannot ask for 5 channels and then go on to use them with 15 mobiles and 15 portables - or an applicant cannot ask for for a 25 mile radius area of operation when the entire community is 1 square mile (unless there is some other mitigating rationale, like they are the dispatch center for a mutual aid). Then again, there are some buildings that have their own trunked system inside. Casinos, manufacturing plants, and hospitals can have their own trunked systems if they have a lot of radios and a need for a large number of internal departments to communicate.
Many of Roselle Park's neighbors are going on to the NJICS system, and, I believe Union County has augmented the system's coverage by adding sites. A few municipalities to the west have also looked into the system instead of building out with their own resources, especially if they have channels on T-Band (470 - 512), as there's a lot of politics involved right now and those channels may be auctioned off.
Why would going to NJICS be appealing? The biggest reason is that even though a trunked system is fancy and can have fancy features, another agency (NJ) owns the infrastructure and pays for all of the updates and maintenance. The municipality buys "subscriber equipment" (mobiles and portables), they get programmed, and that's it. Something goes down? It's the state's problem. Need new firmware for system updates? It's the state's problem. Something goes wrong? It's the state's problem. Municipal expenses are actually reduced over time, even though the radios would cost more in the initial outlay. The only thing the town has to pay for is their own radios and can budget some for an accelerated lifecycle.
The other reason is that, over a period of time, the scales tip in favor of agencies that don't switch becoming the "odd men out" when it comes to operating at a common incident. The VHF frequency could take them so far out of town, but the trunked system has talkgroups that could be used while roaming. Not that I think giving up VHF is a good idea - like any network dependent technology, having and keeping a backup is important in case a point of failure affects your community.

Besides the initial capital cost of the radios..the municipalities have to pay a subscriber fee per radio per year which is not all that expensive. For those agencies coming in under the Union Co umbrella, they are getting a slight discount on the subscriber and TG fees. So their opex is now less not having a maint contract on infrastructure but they still have opex on mobile/portable maint, subscriber fees and they dont have to worry about converting off T-Band later on. They also get STATECOM talkgroups on a statewide coverage area so they do have a means to converse if they are outside their geofence. So if they do go mutual aid someplace else in the state, they have those talkgroups to use as interop channels to talk back to their HQ or to the other M/A agencies involved.
Definitely cost effective and good digital solution which gives the user the ability to operate in Phase 1 or Phase 2. Also the user is not stuck to just buying Motorola radios. They can use Harris, EF Johnson, Kenwood, etc. Giving other radio vendors an opportunity to promote sales across the board while maintaining interoperability.
Then how was Verona able to get a trunked system? The town only has about 14k residents and is 2.7 sq miles.
