New Gillette Stadium Cap Plus DMR System

#1 Post by ErrolW » 25 Jul 2015 21:03

Based on listening to traffic from the Taylor Swift concert over the past 2 nights it appears Gillette Stadium in Foxboro is running a Capacity Plus system in place of some of their traditional frequencies.
I have been able to identify two frequencies:
464.450 (Ch 1 and 2)
451.500 (Ch 3 and 4)

While most traffic is on these two frequencies, there must be a 3rd frequency I have not been able to identify as occasionally DSD+ shows voice traffic (or rest channel) as Ch 5 or 6.

So far I have identified 5 talkgroups, still working to nail down exactly what each is used for.

I don't think this 3rd frequency is another from the WPXL674 license, but can't be sure as from Framingham I'm getting a lot of non-target traffic.

Also noted that the two parking lot DMR frequencies (451.825 and 452.400) are in use but not part of the Cap+.

Hopefully someone who is closer can ID the missing frequency. Unfortunately I'll be in NH for most of August when there are a number of events that would make for good monitoring.

I'm not too far from Foxboro and should be able to listen at some point. Right now I'm working on figuring out the Con+ info for the ICE MotoTrbo network, but will take a look at it when that's done.

Can you type out the information for the DSD.frequencies file so I can update that when I have the chance?

I believe I found the third frequency today. From a different Gillette Stadium license.

Here is the info for the freq file.

; Gillette Stadium Cap+

Cap+, 000, 0, 1, 464.450, 0.0, 0
Cap+, 000, 0, 3, 451.500, 0.0, 0
Cap+, 000, 0, 5, 452.700, 0.0, 0

Thanks. I'll file this and work on it when I have some time.

Errol, you've given me a new challenge!

I set up the system in DSD+, but I'm not sure I set it up correctly. If I understand Capacity Plus, there is no control channel, only rest channels. Right now, I'm parked on Ch. 1/2 and have only heard audio for one transmission. TG 3 seems to be security, but not just for the stadium. There was talk about restarting the escalator at the cinema at Patriot Place. The field unit was "Victor 1".

One 464.450, DSD+ shows the network ID as 2. Rest Channel = 1.

In addition to the beacon signal every half second or so, there are longer data streams with no voice lasting about three seconds. I take that to be data of some sort, but there is no talk group ID, so I really am only guessing.

Now, I'm going to go read up on Capacity Plus trunking.

Hello,

I thought there was a thread on the system, but I did not look back far enough.

I did not noticed the 452.125 frequency active and did not see signs of channels 7/8 being active in the data from the system, but that is not definitive.

I was surprised that it is coming up as a Linked Capacity Plus system. I have seen single site systems configured as linked.
Talkgroup 5 was called channel 5. This seemed like a unit-to-unit channel. There was also mention of an "Events" channel. Talkgroup 1 dealt with parking, "All parking units", etc. The others need some more monitoring to be really sure.

Linked Capacity Plus Site 1
464.4500 Ch 1/2 CC1
451.5000 Ch 3/4 CC1
452.7000 Ch 5/6 CC1

Talkgroups
1 Parking
2 Event Staff
3 Premium
4 Gates & Ushers
5 Channel 5

I am going to program up one of my UHF DMR radios to better monitor the talkgroups.

I'm running DSD+ 2.10 on this system. Mainly to learn how to discover a Cap+ system. I figure that this will verify that I'm doing the set up correctly. I set up the system as described in the release notes and the first frequency I put in is 464.450.

After running FMPA-CC for several hours (with the -rc switch) DSD+ is reporting this as Channel 5/6 with 5 being the "rest" channel. That's different than what's posted here, so I don't know which is correct. No voice yet, of course, but it seems to be working. I am getting TG numbers popping up which seem to match what's posted here.


I'm going to plug in a different frequency and see what information pops up.

EDIT: After playing with this a bit more, I think I have a better understanding of what DSD+ is reporting. Channel 5/6 is in fact 452.700 and that 5 is the rest channel. With FMPA-CC set on that frequency, I'm seeing Radio IDs and channel assignments to 5/6. TG 4 is the only one active so far. Since it's so quiet, maybe the system is only using Channels 5 and 6.

Hello,

If only one talkgroup is active, the rest channel and voice channel stays on the same frequency and swaps channels on every transmission. Two talkgroups need to be active to push the rest channel to another frequency.

With the next 2 events at the stadium you'll hear everything they have, between the Bee-otch-ay concert and then Copa America.

Rumor has it (although off topic) the fake turf is being replaced when they pull up the grass after Copa.

After using DSD+ with the system set up as outlined in the 2.10 release notes, I decided to plug in the information from this page and see how it ran. DSD+ plus works very well on Cap+.
Today the rest channel is 6, with most voice activity on 5.

TG 4 appears to be security related traffic, especially access to various parts of the facility. The base identifies as "Command" and most subscribers identify by name.
Fallon P12 was heard calling someone on TG 3, but received no answer so I didn't catch who it was. I know that Fallon provides transport for events at the stadium and also provides transport for the Partners medical facility at Patriot Place. That bears further watching.

Is it time to set up a Wiki page for this system?

There is a page for Gillette, but not much info on TRBO.

We can add the MotoTrbo trunk to that page. It would certainly save some work.

With the DMR scanners here/coming, there is likely to be some interest in listening to it. A couple of people have asked me about DMR scanners in general and are looking for TG information already.

With all the new scanners and upgrades, I hope we'll get some more listeners and ID some of the unknown TGs on the ICE and Comtronics networks.

But, I digress.

I've been running this system in my Uniden 436 since beta release with mixed results. It worked really good the 1st day, which also happened to be a soccer game day. It's been really quite since. I figured there would be more traffic if this system is used by Patriot's Place Security. Maybe they're on another DMR frequency not in this Cap+ system? Agreed that a wiki update would be good to have. Thanks to those doing the monitoring and reporting.

I don't know if it is used by Patriot Place as well as the stadium. The traffic I've heard so far doesn't seem to indicate that, but it hasn't been all that busy. This morning, both OTA channels were used on the rest channel and the rest channel was moved to 464.4500 for a few minutes. When that happens, DSD+ notes "Lost Rest Channel moving to 464.4500, but when one of the OTAs on that frequency is used, I get no audio.

The FMP24.VC window shows that the frequency is being generated but there is no actual activity. I'm trying to figure out if the channel order is wrong, but so far hasn't had much luck.

Even when back in the Analog days the channels were used for both the Stadium and the Stores
The Stadium got priority on Event days for radio traffic

It seems that might be the case, but I'm not 100% sure yet from listening. I can confirm that the Brigham/Partners health center has the ability to talk on the system. As does Fallon Ambulance. They both seem to use TG 3.

On a DSD+ note, I finally figured out what my issue was with the system not switching to the back up rest channel when OTA 5/6 were both busy. I forgot to hit "save" when I added the -rc switch to FMPA-CC.bat. Once I corrected that, when the rest channel was lost on 452.700, the system correctly switched to 464.450.

Of course I had to be down on the Cape tonight, so I can't listen.

From what I have heard, 3 is used for access control and security, at least when there are no events.
