New Jersey Interoperability System on TRX-1

[jackmail226]

Hoping to get some help on the NJICS (NJ Interop system, P25 II)
I am trying to program this system into a TRX-1 and I have updated the EZscan App, the Firmware and Library but I get nothing coming in on the scanner. It downloads and all the frequencies and talkgroups appear to be in the scanner but it is dead silence for hours on end. Talkgroups and system frequencies are taken from the RR database and I have tried towers local to me and then the entire list of sites. I am in an area (Lake Hopatcong) where I know there is coverage. Does anyone have any ideas as to what I may be doing wrong?

What are you trying to listen to, which agency? Have you looked in the database to see if there is a e or E in the mode column, that would mean it is encrypted. Have you tried scanning with a wildcard? Have you made sure the tower/site you entered are within range?

These are the only TGs from Sussex Co where Lake Hopatcong is located, others maybe in use but not identified yet or encrypted.

For starters only scan the sites closest to you. Many of the sites are simulcast and that might not be the best scanner. Try scanning from different areas and try other antennas if you have any. What county are you in? Try locating a site that's not simulcast.



Seems that radio has adjustable gain.

TRX 1&2 on a 700 MHz Phase 2 Simulcast System

I am attempting to monitor a new Atlas 700 MHz simulcast system with my TRX's. I am getting horrible reception. Have tried different antennas, it is on an outside antenna now and still not getting much traffic. Not even going digital, it is missing a huge amount of traffic. I am 8 miles from the...

Using a trx1. I monitor NJICS everyday from the Bordentown simulcast site that is directly across from me. I am on the Pennsylvania side right on the river.

I just monitor C3- 10 which is the NJSP Marine Division and C3- 01 division call which is the NJSP Aviation. Occasionally I listen to C3- 02 that is Trenton police dispatch in the clear.

I personally have never been able to get the trx-1 to work on any phase ll simulcast, it also does not work on Bucks County or Burlington County for me.

Maybe it works for others but I've never heard about it. Works fine on SDS series.

That's because you're only within range of the Bordentown Simulcast site physically in Bordentown. The other (3?) sites aren't a factor for LSM distortion to be an issue on a TRX-1

I don't follow John, right next to the Bordentown site we have the Trenton simulcast site which I could also use if I wanted and when I'm in Trenton that's what I would use. I only listen to one site at a time.

I have tried using it in other locations on NJICS using the closest simulcast site to my location and no go. That goes for the Cape May simulcast site also when I am in the Villas.

Unfortunately my own County as you know has been using Phase ll simulcast for over 10 years, it has never worked on a trx1 for anyone I know.

Can't believe we're debating this age old well known fact 🤣.

Hey if somebody can get it to work using the voodoo that they do do more power to them. As you, of course know, it's location location location. I just never found that location on a trx1.

I don't have a dog in this fight. Trx1 is a neat little radio, still love my PSR 800 as long as I don't need to hear phase ll simulcast.😉

Right but keep in mind that each simulcast cell is composed of several individual sites which all transmit the same transmissions on the same frequency at the same time. I'm saying you may only be within range of one site on the Bordentown Simulcast. When you visit Trenton, you may only be within range of one site on the Trenton Simulcast, so simulcast distortion may not be an issue if you can hear all transmissions clearly on your TRX

I am trying to get the Marine unit on Lake Hopatcong here in N.J.
The RR database has talkgroups in the library (DEC - 4 digit talkgroups) and I have selected and loaded them using EZscan. I always thought these talkgroups were 5 digits such as 35952, 35120 and 36784 but I see no 5 didit groups in the library...
At this point would also be happy to listen to any traffic on that system as well - just to know it is working.
I have a tower located in Netcong which is very close and another one called Bowling Green which I understand is located in Jefferson Twp. and that is close too.
To try and avoid the simulcast, I have set the scanner up for monitoring each one of those sites individually and still no signals whatsoever.
I know the scanner is working because I use it in other geographic areas on totally different systems and it seems to be working, so I'm thinking that I am missing something in the software process.
As a note - I am almost literaly on the border of Morris and Sussex counties in NJ on the west shore of Lake Hopatcong...

Of course each simulcast site consist of sub sites that transmit simultaneously.

That's why the 100 and the 200 that have SDR chips in them receive NJICS flawlessly. By the way they would only work as well as they do because I have a Larson triband on my car and a rooftop antenna on the house so there is no breaking up of signal not receiving the furthest sub site from a simulcast site with the 100 and 200.

From home I could really use either the Trenton simulcast site or the Bordentown simulcast site, the Trenton site is just North of the Bordentown site, likewise when I'm in Trenton I could use the Bordentown simulcast site successfully.

The TRX 1 is P2 capable and not all phase ll is simulcast. The TRX difficulties with phase ll simulcast is a well-known fact.

Occasionally when I am in lower Township, the Cape May simulcast site also works flawlessly on the 100 and 200 but does not work on the trx1.

You know me long enough to know that I do know a little something about this stuff.😆😆😆..

If it makes anybody feel better, the 436 and the 536 doesn't work so great on Phase ll simulcast either, better than a trx1 but not great.

As far as North Jersey goes I'll be the first one to tell you that I never go up there, wouldn't even go close to New York City for anything so what happens up there I don't know, I'm not familiar. Central and South Jersey, I know.

Just a miscommunication here, again I think you know my experience as I do yours.🙂

Indeed. Our combined experience and simulcast posting make the RR forums a great place
