Massachusetts Convention Center Authority

#1 Post by deputydog522 » 15 Jul 2016 08:41

The MCCA just starting using thier new 800MHz Hytera DMR system. They have left the MSP trunking system and now on their own system. 3 total sites- BCEC Seaport, Boston Common Garage, Hynes at the Pru. Its a local on site system and works only while you are in or around each one of these locations. No more wide area coverage.

Hello,

I was able to copy a site going home through Allston and downtown, but did not have it setup. I can not copy anything from Lynn (sometimes I can copy low power Boston sites) After the MIT Fleamarket, I was able to do some more monitoring in Cambridge and picked up more data. Activity was on Slot 2 of the Control Channel and not very Active.

WQVN280 Massachusetts Convention Center Authority
Network 100

Site 3 (likely Hynes)
854.6625 Color Code 1 Control/Voice LCN 294

The Boston Common Underground Garage was using MCCA talkgroups on the old system. It appears one site is for the garage and licensed for 854.0375 and 856.0125 only. The other two sites are licensed for all the frequencies.

Given the monitored LCN, I suspect the LCN map has a base LCN (1) of 851.0000 with a 0.0125 step.
854.0375 244
854.3375 268
854.5875 288
854.6625 294
856.0125 402

I noticed the MCCA also has a DMR license out in Springfield.

Hello,

It turns out I can get Site 3 with fading at home with the beam. I received four talkgroups so far, 1048678, 1048679, 1048680 and 1048779. Unit IDs are in the 104xxxx and 105xxxx range.

System ID is Tiny Model Network 100 Site 3. I am not getting any Hytera proprietary messages, just standard Tier 3.

Hello,

I was in Boston today. It was neat listening to the MBTA while riding underground.

I checked out the BCEC, Boston Commons, and Hynes areas with the scanner. I blended in with all the people playing that Go game.

Site 3 appears to be simulcast sites at both BCEC and Hynes. Strong signals without an antenna near both locations. Activity was on 854.6625 as only one talkgroup was active at a time. I heard security activity.

I also picked up Site 1 in the area of the BCEC. I heard it with a weak signal with the antenna off. Frequency was 854.0375 Color Code 0. I did not hear any activity.

Site 4 is located near The Boston Underground Garage at the Common. It also uses 854.0375 Color Code 0. I was picking up security talkgroups using 856.0125 Color Code 0 as the voice channel.

I suspect Site 1 is used for BCEC Parking and Site 3 is used for BCEC/Hynes Security/Ops.

I know this is an old thread, but thought I'd revive it.

I'll have some wait time in Boston next week, so I might be able to do some listening.

Can this be monitored with DSD+? If so, can someone post a sample of how it's set up?

Also, can the x36HP scanners receive this system?

I had some wait time at Logan, so I set up my SDR/DSD+ system.

I had great copy of the BCEC without an antenna and DSD+ was very informative.
DSD+ reports the system as "T101", but will not allow the "T" to be used in set up. So, I set it up as 101. DSD+ also reports the site as 2.2, but has no neighbor sites shown. the only active frequency was 854.6625, which was the control channel and the active voice channel. 589 is the control channel, 590 is the voice channel. The system wasn't very busy, but I expect that if there is an event there, it will be more so.

Color Code is 1.

The only TG I saw was 1048779, which Eric reported earlier in this thread.

I might have some monitoring time again tomorrow, but that will be very early in the AM, so there might be minimal or no activity. There is nothing scheduled until next month.

This is how I have DSD+ set up on my laptop for the BCEC.

TIII, 101, 2.2, xxx, 854.0375, 0.0, 0
TIII, 101, 2.2, xxx, 854.0375, 0.0, 0
TIII, 101, 2.2, xxx, 854.3375, 0.0, 0
TIII, 101, 2.2, xxx, 854.3375, 0.0, 0
TIII, 101, 2.2, xxx, 854.5875, 0.0, 0
TIII, 101, 2.2, xxx, 854.5875, 0.0, 0
TIII, 101, 2.2, 589, 854.6625, 0.0, 0
TIII, 101, 2.2, 590, 854.6625, 0.0, 0

The Hynes also has no events until next year. Parking is much harder, so I don't know if or when I'll get to listen there.

I get intermittent reception not far from Logan with a 436HP and a SRH77CA. I have it plugged in as follows:

854.0375 - LCN 244
854.3375 - LCN 268
854.5875 - LCN 288
854.6625 - LCN 294
856.0125 - LCN 402

I've logged about 30 TGs and have tentatively ID'ed about 10 of them. Let me know if there's any interest in them.

Sure, post the TG information.

I don't know why I've got different LCNs for 854.6625.

856.0125 should be parking, along with 854.0375.

I don't know when I'll get back to monitoring, although the car show is at the BCEC and should bring some interesting monitoring with it.

If memory serves, I got the LCNs from a post from either RR or here a few years ago and they seem to work, but I'll give LCN finder a try during the Auto Show if I get good reception.

For TG's, I've confidently identified the following:
BCEC
1048678 - MCCA Public Safety BCEC
1049278 - BCEC Transportation Services
1049280 - BCEC Shuttle Buses
1049281 - BCEC Valets
1048688 - BCEC Securitas contract event security -- mentioned as "Channel 10"

Hynes
1048679 - MCCA Public Safety Hynes

Boston Common Garage
1048680 - MCCA Public Safety BCG

Tentatively ID'ed/ Need IDs
1048778 - events setup, setting up trash bins and tables, ABM (American Building Management)mentioned, heard when shows were at both BCEC and Hynes
1048779 - Similar traffic to 1048779, but when events were at Hynes and not BCEC
1048978 - different people attempting to hail electricians at BCEC, BMS mentioned frequently, building maintenance issues (plumbing, ITS Operations, ABM mentioned) - "Electricians might be on Channel 3"
1048788 - the channel the electricians answered up on for the BCEC
1048979 - "xxxx to BMS" - discussing cleaning & adjusting AC's in halls A&B
1048789 - Discussing extension cords, "GBE to electrician" "They might be on 1" - Dalton Street mentioned so likely Hynes
1049078 - Dishwashing, food, credit card readers mentioned, "Call banquets"
1049679 - discussing buses and students when a high school event was at Hynes
1049279 - Similar traffic to BCEC Transportation, posts and parking mentioned but unknown location

There are a few more TGs with snippets of traffic on them that I didn't catch enough from to get much context. They do seem to have far more talkgroups than when they were on the state analog system, that's for sure. Unfortunately reception from my location is iffy, sometimes it's fantastic and sometimes it's completely nonexistent.

Good information, thanks.

I might have some time tomorrow to listen in and will try to nail down the LCN. Good idea running the LCN finding.

I forgot to ask, are you using a x36HP scanner for listening to this system? Are there any special settings needed for a Hytera system?

I do, it's been a while since I set up a TIII system but the only difference I remember is that the LCN numbers are much higher than on other systems. I did notice that on another TIII system (JetBlue) the LCN finder didn't find a LCN for the channel that is beaconing.

I did some listening with DSD+ and my 436HP side by side. LCN finder worked to the extend that is showed the same (294) channel number as you're using. I then listened in ID Search mode and got nothing. DSD+ shows the same LCN (589) as used previously. For DSD+ I found that I had to enter each frequency twice to get voice. The second LCN for the control channel is 590. Set up that way, DSD+ followed the system correctly.

A very slow day at the BCEC today and in an hour of listening, I only heard a few voice check ins. There are a lot of ID checks without voice.

When the Auto Show is there in a couple of weeks, I expect that the garage and the convention center sites will be very active.

I remember reading something back when DMR for the x36 was in beta mode that a firmware update resulted in having to divide the LCN in half and rounding down for LCN on TIII systems. I've noticed that the 436 doesn't seem to track the JetBlue system as well as it used to, but I'm not sure if that was due to a firmware update or due to the control channel changing to 460.800 from something in 450s.

I'd be interested to see what happens when you run them both side by side again when there's actual traffic to catch. If you're able, try using the LCN order I was given and seeing how it tracks.

If I can make my way into Boston when there is something going on there, I'll give it a try. The LCN thing is interesting. I'll give programming the 436HP that way a try.

The two times I've been there so far, there was nothing going on and so there was minimal traffic.
