Stamford CLMRN

[msingewald]

As of now, it looks like only certain TGs like Police and Fire are being carried on both Stamford and CLMRN system, and the others are only being carried on the Stamford "Site". Stamford had a TON of TGs on the old system, and it seems that most of those won't be allowed to roam onto the CLMRN sites, so what will happen in the database going forward?

Will all of those Stamford TGs show up in the CLMRN list, or will Stamford continue to have it's own section?

From watching the log this morning, I am seeing MTA and some busses getting denied access to the Stamford site. Curious how this all works out with CLMRN users and if they will be allowed to roam onto the Stamford site. Also not seeing any TDMA activity on this site yet.

They will show up on the CLMRN list when they are discovered in use, or whoever deal with those departments/divisions of city get the radios set. Unfortunately I believe a lot of the TGs listed on the old page were never actually in use but rather discovered using SDR trunk decoding software during the implantation/testing. If you wish to see how this will be displayed, you can see Worcester or Cambridge CoMIRS in Massachusetts, or New Britain here. So it's not difficult to program into the scanner, just avoid all the zones except G and Stamford and it'll be just like trunking them stand-alone.

Mike, thanks for the explanation. I guess what I am getting at is that a number of TGs will only be heard if you lock to the Stamford site. If you are near Stamford but your radio is on the Troop G system, you will not hear many of the TGs. Useful info that has no way of being shown in the database.

For example, many FD calls dispatch on the main channel, which is on both systems, but then switch to a Fireground or TAC channel, which don't currently seem to be on the Troop G system. Not a huge problem, but worth noting if the database supported that kind of info.

BTW, I see you posted at 3:30am. That is dedication!

When I was living in Stamford, the traffic on the P25 system was 95% on the PD, FD and EMS, all the "Future Use" talkgroups never had any affiliation or traffic carried on them.

Stamford FG was on 700 MHz simplex conventional, that probably hasn't changed with the migration to CLMRN.

 

[msingewald]

The FG is still simplex, but it is carried on the trunked system as well, if that makes sense.

Makes total sense. A lot of departments "repeat/broadcast" their fire-ground traffic so incoming units can listen only and hear what is going on, as well as having their fire-ground communications recorded.

Also I'm picking up Stamford Fire Dispatch on the Troop I site.

 

[msingewald]

Listening to the plows this morning on 23559 and wondering what channel this would be. In the old system, DPW had many channels, and I wonder which this would be.

Choices from the old system would be:

City Fleet
City Garage
Storm

Since this TG has been active even before the storm, I would rule out "Storm". Suppose I could submit it as City Fleet and or just describe the ops and let the DB admin pick the name.

Ran Uni trunker on the G system this morning since Stamford started the upgrade and it shows the Stamford system as a Peer.
I wonder how long it will take...If they stay FDMA its just reprogramming, If they go TDMA that's a crap ton of mobiles they have to swap out

As far as the Radio ID's go, here's a few ranges I have observed (mostly based on hits in UniTrunker)

1351004 - 1351411 = Stamford Fire, maybe EMS also
1352001 - 1352304 = Stamford Police
1353xxx = Seems to be mostly PW and other but have seen them pop up on PD & FD TG's
1354001 - 1354298 = Stamford Fire, maybe EMS
1355002 - 1355810 = Stamford Police
1359xxx = Dispatch consoles

I have noticed with testing going on with Stamford as well as Trumbull, it sounded like radios with an ID like 135x9xx were being used by radio service.

So I only realized that they were now on clmrn last week after updating my db. I only hear FD/EMS dispatch on there , nothing from PD like I read above. Not sure I understand , are they staying on the State System?

 

[W1KNE]

So they are staying on the state system, with their own site. If you only want Stamford, you only program in the Stamford site and Stamford Talk-groups off of CLMRN. Conversely, you can download the whole system using software and just avoid or delete all the sites except for Stamford and avoid or delete all the talk-groups except for Stamford. You'll only hear Stamford if you are within signal range of the Stamford "site". You won't pick up Stamford on CLMRN from say, New Hartford, for example.

PD is very active but still Encrypted. I'm not sure but I would imagine that the new PD radios have AE$ and they will change from ADP to AE$, I don't think the state lets ADP on the system but that's just a guess

New Britain PD is still ADP

Not sure if it's still temporary while everything is transitioning, but I am seeing a few Stamford PD TG's (23532 & 23538) on the G & I simulcasts and Fire/EMS Dispatch (23507) on G.

It all depends where the groups are allowed or not allowed. It is one of the selling points of the system to municipalities to have coverage beyond the range of an existing system. I will sometimes hear Norwich, Groton, Stonington, New Britain, Stamford, etc on Troop H site. But, it is, for the most part about affiliations. So if the Groton Police chief has a meeting in New Haven, he can expect coverage driving to and from such a meeting.
I would expect at some point to see issues and then some limitations. Perhaps some of the cells with only 6 frequencies (10 talk paths) might get a few more or would see some groups blocked. The folks that run the system have done a very good job so far as the system gets loaded more and more.

I am in Norwalk but only hear dispatch , no other TG ‘s.

The reason New Britain is set up with their own site is because they are keeping their old system. They have I think a 3 year contract with the state and when that is up they will see if the want to go back to their old system or stay with the state. Maybe that is the thinking with Stamford.

New Britain is still on the same system they have always been on, they just switched to the state core, The state does not require a contract really just a MOI and you can leave any time you want, its a huge cost savings to go on the state core and it gives you many more options and out of town coverage.
The site just corresponds to the place on the system, since New Britain is a campus system they get a site number if they just went on the state towers like some other towns they would just have talk groups and share

I had programmed the Stamford site into my 325P2 after seeing this thread when it started. Sitting in Meriden today I picked up Stamford Fire on the Troop I. Full 4 bar reception. Sounded nice and clean and clear
