Worcester P25 800MHz Trunked (unknown talk groups need identifying)

Post by sawyer100 »

Wed 7/3/19, heard, but each one is scrambled or encrypted: 4373, 4375, 4379, 4387, 4393, 4397

none of these six (6) are in the WIKI. Any idea what/who they are (i.e. FD, PD, school, parks, DPW, etc) ?

All these talkgroups are for the PD (encrypted). I have identified a few as they move to another talkgroup (unit on F1 says go to F4 and they show up on a different talkgroup).

4375 is PD F4 (used to be traffic enforcement on the old EDACS system)
4379 is PD F6 (used to be TAC 1 on the old EDACS system)
4393 is PD F9 (unknown use)

Thank you franciedog for your help! At least I can alpha tag them with the correct channel #/alpha name.

Can you confirm that isn't a typo? That TG is already in the wiki as DCR-FIRE 1. (691 digital *16=11056 analog)

On the old system, every division had their own channel 4. So there was an operations-4, a traffic-4, etc. I have not listened to or tried to track down their encrypted channels, so I have no idea if the new system is set up the same way.

MEMA Dispatches for DCR, so likely they keyed up all channels from the Console or patched for some reason.

691 Digital = 11056 Analog = DCR Fire-1

My Uniden BCD996P2 scanner, I have it in {search mode/ID search} when I monitor the Worcester P25 system. It definitely showed:

screen:

691 {this row is the alias alpha tag. When no tag, it displays the t/g #}
691 {where it displays the talk group number}.

Now when MEMA was talking on the Worc system, the outbound audio was P25 digital, not analog. Now I used my 2nd BCD996P2 and locked it on the MEMA VHF rptr (i.e. Princeton 151.4525 Rptr PL 229.1}. So I was hearing the MEMA VHF first, and about 1.25 seconds later it was coming out the Worc system as P25 digital audio, same conversation. So the Worc system must hear the MEMA VHF, and it transfers it over to P25 digital audio.

I guess it could be possible MEMA transfers it out MSP 800 as DCR-1, but that means Worc rebroadcasts the DCR-1 talk group, which I have never heard. Unfortunately I didn't have a chance to jump my 2nd BCD996P2 to the DCR-1 talk group and see if came out there, or not.

I snapped a cell phone pic of my screen. It does say 691 on the two rows. and I have the MSP800 & Worc800 as separate systems in my scanners, so it doesn't confuse control channels/freqs, etc.

These systems are all tied into the core in Framingham and that is where MEMA dispatches from. See Bill's post above it was probably a console mistake.

I just saw TG 691 (which I had as DCR Field Ops but I guess that's wrong) come up on the 700MHz overlay in Boston with the same audio that was going out on MEMA UHF 471.6875 NAC606 in Boston with a Severe Thunderstorm Warning so once again they seemed to be simulcasting across the console. But 691 obviously leaves the core and goes far beyond just the Worcester system as I don't even get that here in Newton.

MEMA Dispatches for DCR, so it is very likely they do an ALL Channels for these Weather Alerts

Correct, any weather related broadcast is simulcasted over MEMA VHF, MEMA 800MHz, DCR VHF and DCR 800MHz. Also the 0800 and 2000 hours radio ID will also come over all of them.

*** RE-CONFIRMATIONS ***

After a brief, educational, informative lesson from a member here, so I could better understand the City's P25 system's role, I then edited my Uniden BCP996P2 scanner settings to listen to who talks on a daily basis (Worcester & non-Worcester users). After 8 days of listening 24/7. Here is a "re-confirmation" of active talkgroups for the WIKI. NOTE: Some talkgroup ID's are new & not yet in the WIKI:

WORCESTER:
51 Worc Airport Fire
85 F-PTL-3 Worc Airport
183 Worc Airport Maintenance
185 Worc Airport Operations
2507 Fire Dist7 ORG simulcast
2509 Fire Dist8 simulcast
4351 unknown user (encrypted)
4369 Worc Police Ch1 Dispatch - East
4371 Worc Police Ch2 Dispatch - West
4373 Worc Police Ch3 CJIS (encrypted)
4375 Worc Police Ch4 Traffic enforcement (encrypted)
4377 Worc Police Ch5 talkaround (encrypted)
4379 Worc Police Ch6 TAC-1 (encrypted)
4383 Worc Police Ch? ??? (encrypted) Heard 1st time ever Wed 2/19/20
4385 Worc Police Ch? ??? (encrypted)
4387 Worc Police Ch? ??? (encrypted)
4393 Worc Police Ch?9? ??? (encrypted)
4395 Worc Police Ch? ??? (encrypted) Heard 1st time ever Fri 2/21/20
4397 Worc Police Ch? ??? (encrypted)
4433 Worc Fire Ch1 Admin
4435 Worc Fire Ch2 OPS-A North
4437 Worc Fire Ch3 OPS-B South
4439 Worc Fire Ch4 OPS-C
4443 Worc Fire Ch6 Dispatch
4451 Worc Fire Ch? Fire Prevention
4477 Worc ??? Heard 1st time ever Thur 2/20/20. 20 seconds of quick chit chat, user TBD.
4481 Worc EMS Citywide
4485 Worc EMS 2 Fire/PD
4513 Worc DPW Snow plows
4515 Worc DPW Garage
4517 Worc DPW Sewer Dept
4519 Worc DPW Street Dept
4521 Worc DPW Water Dept
4523 Worc DPW Engineering
4525 Worc DPW Water Filtration
4527 Worc DPW Sanitation
4529 Worc DPW Parking
4583 Worc 911 Emergency
4585 Worc Fire/EMS/PD
4589 SP Holden tie



NON-WORCESTER / MA STATE TRS USERS:

691 DCR FIRE-1 {i.e. 11056 analog talkgroup ID} Heard back on 7/24/19, nothing recent.
2217 MSP Statewide {i.e. 35472 analog talkgroup ID}
2283 MSP LOCPS-7 C tie {i.e. 36528 analog talkgroup ID}

so what I'm saying above, is when the analog TRS system ID's (above) talk, it comes out the Worc TRS system on P25 ID's (only 2217 & 2283). When other analog talkgroups ID's talked (separate scanner), they did not come out over the Worc P25 TRS system. I was just trying to compare which analog traffic t/g's came out identical on the P25 system (having a P25 t/g ID) on a daily basis, etc.

I was recently told that the Worc. Red Cross Chapter is operating on a tg on the Worc P25 system. I do not see them listed anywhere in any data base. Can anyone confirm or debunk this? And if so, what tg are they assigned and if not, what freq are they operating on?

additional (new) discovery items to my initial post above

WORCESTER:
631 Worc EMS Wide Area
4445 Worc Fire TAC10 FG2


NON-WORCESTER / MA STATE TRS USERS:
675 DCR Emergency {i.e. 10800 analog talkgroup ID} (hear every day during MEMA 8:00pm radio ID multi-cast)
2431 MEMA Statewide {i.e. 38896 analog talkgroup ID} (hear every day during MEMA 8:00pm radio ID multi-cast)


* I will try & listen to see if I hear any Red Cross traffic.
* Does anyone know if the Worcester Housing Authority is on this City trunked?
* Does anyone know if the Worcester Health or Building Enforcement is on the city trunk? Only ask because they had their own radios systems prior to the former EDACS and/or were on that EDACS system.

the last additional (new) discovery items to my initial posts above:

WORCESTER:
4447 Worc Fire Ch? TAC11 FG/Training
4561 School Transportation A


NON-WORCESTER / MA STATE TRS USERS:
671 DCR 8 Field Ops {i.e. 10736 analog talkgroup ID}
2209 TECH Statewide {i.e. 35344 analog talkgroup ID}

I'm done monitoring Worcester TRS for a while. I going to switch over to my next project & start monitoring the MSP analog TRS on a daily basis. I will continue to report here on every talkgroup talking on a daily basis, for the next 30 days straight. As a 2ndary part, I'll observe when an analog talkgroup talks, if it comes out on the P25 side (analog ID divided by 16 = digital ID).

A quick programming question.... I live in N. RI and have programmed in the new Worc P25 system into my 436. I am unable to pick any transmissions in my area, even on a outside rooftop antenna. I went for a ride and was only able to pick up tx's on 146 near purgatory chasim which is about the half way point for me. The 436 was attached to a 800 antenna on the outside of my truck.

I was only able to get about 3 bars and scratchy messages. I know of others that can receive tx's in NRI with no issues so I assume that this operator error on my part during programming. I used the freq's & tg's listed in this wiki.

What the heck am I missing... should I be programming in the other listed sites to get better reception?

Thanks,
Iggy

The system is designed to work in and around Worcester. I don't get it when I'm down in the Hopedale/Mendon/Milford area unless i'm up on one of the hills.

I concur with Gary, the system does not work well if at all more than about 5-10 miles outside the city. It also was not designed to. The put a lot of effort into ensuring coverage in the city and part of that included moving one site from Paxton to ORH. This killed a bit of coverage outside the city but improved it on the west side of the city which was the goal. While they added a southeastern site for gap coverage along the Rt. 20 side of Grafton hill, this is fairly low lying and again does the job it was intended to do.

They specifically set it up this way to ensure it worked well for them. In the rare event they leave the coverage area they have the areawide talkgroups on the main MSP system so that they can still talk back if needed.
