CoMIRS question

[stormycat]

I have tried to figure this out over the past few months on my own with out asking questions. But I’m stumped. I travel on 91 from the CT line up into Franklin county very often and I have the new CoMIRS system programmed in and I get absolutely nothing from the CT line all the way up into Franklin county. I was under the impression that this system was up and running and I could monitor troop B and Franklin county fire and police dispatch. Any help would be appreciated thanks

Franklin County is almost entirely running off of CoMIRS for Fire and Police. You most likely have a programming error somewhere

I always hear Franklin county and troop B on the Massachusetts state police system

On Comirs or the analog system?

 

[Chevyclub]

Not on Comirs but programed in the Massachusetts state police system

Yeah I can pick up the state police system just fine. I’m trying to figure out if COMIRS is online for troop B and if I can pick it up in the Springfield area

I have tried to as well never heard anything as well

Interesting. everything I see in the data base shows it being online yet i don’t get anything on it.

I've always found Springfield to be on the very edge of the CoMIRS western MA system. In that area I always hear more on the analog system still in use along with the CoMIRS system.

There is a site in Franklin County, but I believe it to be mostly there for Franklin County public safety.

It's important to remember that P25 systems are more "granular" in that you will not hear all TGs on all "campuses" (sites). Technically what ties everything together is the Motorola radio core, which almost all of the P25 systems in MA use. Maybe it's actually ALL. Even though Worcester uses TGs that are consistent with CoMIRS, I'm not sure if they use the Motorola core as they are a Harris system.

W1KNE knows the system very well, as do a couple of other members.

Confused yet?

The best information out there is at this location. Massachusetts Commonwealth Interoperability Radio System - Scan New England Wiki

The expansion of CoMIRS is supposed to start coming on line next year, but big projects like this often run behind schedule.

I alway monitor CoMirs in the area you r referring to. Never have an issue. What type of station r u using?

I'd venture to say they're on the core with their *Motorola system.

CoMIRS is the entire system, there is the mostly analog Motorola Type II portion and the P25 Phase 1/2 portion.
The sites that are in the B South and B North Simulcast cells are located where I-91 coverage is decent top to bottom. However, remember that the Western MA P25 portion is designed as a mobile based system and coverage is designed for that. There have some additional sites built since the original buildout both in the Simulcast and as standalone sites.

All that said, to get nothing indicates programming issues at your end. Also, you don't mention the scanner used so there could be some simulcast issues if you are using a non SDS radio. However, to get nothing from a P25P1 TRS is odd.

Do you see bars with the control channel when you are in the area? Coverage is pretty good down towards Hartford so anywhere there north should be receiving it. I am in Granby (CT) and it is a strong CC signal here on 853.9000.

I thought it was a Harris system.

It is not, all of Mass is on the state Motorola core, State Police Analog/Digital sites and the satellite sites for Worcester, Cambridge, Metro700, Massport

Okay I thought this was a phase 2 system. I will bring my BCD396XT with me and see if I can get that to lock onto a CC. What I’m trying to use to monitor it with is a G5. That’s what I’m having issues with. but that fact that you have a good lock on a CC that looks to be on the western mass south site in granby means something is wrong on my end. you answered one of my questions as well as to what site covers the best down to the CT line

Thanks. For some reason I thought Worcester was Harris.

Back in the day when it was its own EDACS system yes, but that went away in 16

It is a Phase 2 capable system but there are no Phase 2 talkgroups out in Western MA... yet.

I was probably thinking of the MBTA P25 system that will some day replace their EDACS Pro Voice system.

Per this thread on Scan New England. In theory they could still use the CoMIRS core, but knowing how the T loves to spend money, I won't be surprised if they don't.
