New City Of Boston 800 Trunk

[ScanBoston]

I'm now hearing Morse Code ID's on
859.9375
859.7625
858.7625
858.3875
857.7625
857.3875

All part of:
1 KNJA565 CITY OF BOSTON, POLICE DEPARTMENT 0004890190 YE Active 05/04/2033
2 WRPQ606 CITY OF BOSTON, POLICE DEPARTMENT 0004890190 YE Active 03/07/2032
3 WRTF565 CITY OF BOSTON, POLICE DEPARTMENT 0004890190 YE Active 06/10/2032

I have not picked up a control channel yet.

Also topic made sticky.

Interesting! Is much known about the intended use of this yet? My understanding was that Boston used to have its own 800 MHz trunk, then shut it down in favor of using Zone 1 and the 700 MHz overlay: https://www.snewiki.com/wiki/index.php/ ... y_Services

Wonder why they're switching, and if this will be standalone or linked into CoMIRS.

[ScanBoston]

All of that is true but they have decided to move back to thier own trunk. Not sure how related they will be but they are still friends. Police, Fire and EMS are still keeping thier main presence on UHF. This will be for all the other agencies and USAI.

[garys]

My understanding, which might be wrong, is that there are actually two cores and Boston controls one of them. Which means that they can still be linked, but Boston will control their system independently.

Why?

Because it's Boston.

You'll only know for sure when the system ID comes online. You can't have duplicate system IDs. If Boston sets up their trunk as a stand-alone, it'll likely be setup with Inter Sub-System Interfacing, that will allow travel across the trunked systems. (CoMIRS and Boston), should it be done that way. We know from recent events that CoMIRS is setup for ISSI, and from what I've heard CoMIRS and CLMRN are setup for it to be used for each other as well.

It is simply redundancy - the ownership or control of the hardware is irrelevant in this case.

Getting a weak Control Channel on 852.3500 trying to decode it.

[ScanBoston]

Neverminded I think my crappy scanner front end is leaking through from neighboring MSP on 852.3375.

[garys]

I'd keep listening John. I'm getting it very weakly south of Boston, but either the signal is too weak or it's not digital.

Also, while the MSP has multiple licenses for 852.3375 they are all pretty far west and I didn't see any listed in either the analog or CoMIRS wiki pages. I might have missed it if it's there.

DSD won't even decode it - but it is 852.3375

I’m receiving 852.3375 fairly well west of Boston - 3 bars on my 436 with the stock antenna, but when I added it as a Motorola analog trunk and as a P25 trunk I get nothing. Also, plugged the frequency into Unitrunker and it doesn’t decode even though the SDR sees the signal.

[W1KNE]

I am hearing data on 852.3375 but it doesn't sound like a control channel to me. It sounds more like some sort of high speed data.

[garys]

DSD Plus shows 852.3375 as ProVoice TS. Not the TS, so I'm lost.

[garys]

851.4000 just lit up as the Control Channel.

I haven't seen a System ID on DSDPlus, but the Site is BEE00.944-1.1 with a NAC of 941.

Screen shot from DSDPlus attached. The only TG that has been active is 32773.

[garys]

ETA: I programmed this into my SDS100 and 536HP. Both are receiving it, but only marginally and aren't holding onto the control channel. Looking at FMPA, it's doing better, but it's an Airspy.

I expect that they have only one site online as of now and we'll get better signal as the build out continues.

Sorry to keep replying to myself, but information is coming in pretty quickly.

I'm now seeing

"BSI-WRQA890 858.3875"
"BSI-WRTF565 857.3875"
"BSI-WRPQ606 858.7625 "
"BSI-WRQA914 857.7625"

I'm guessing that's the FCC callsign, but I don't know what BSI means or why I'm seeing it.

32771 was/is patched to BPD Channel 5.

Edit. It appears 32771 is also simulcasting BPD Channel 2 as well.

[Lex998]

I just heard BPD channel 2 patched to 32771.

Also, the new system recently identified as Essex County Sheriff with the control channel of 774.70625 is also system ID 944 and TG 32771 is active on the site as well. I’m on the fridge for that site. I’m able to pick it up on Unitrunker well enough to log it a little bit but not enough to receive voice consistently.

[W1KNE]

Now I only hear BPD 2 there. Clearly this is still early.

You have Boston backwards. I just checked and verified with my SDS. NAC is 941h and System ID is 944. They're the same as Essex. They were backwards on the wiki. (My fault, since corrected).

My apologies, that's what I get by doing wiki stuff at 4am.

Sounds like the 32771 patch or whatever it was, has dropped. Been radio silence for a while now.

[AJ1L]

Anyone know if this system is currently on the air (3:45 PM on 3/3)? I just tried all of the freqs listed in the wiki from Revere and I'm hearing nothing.

[ScanBoston]

I can't get lock on it in Medford at work either. I see some signal just not enough. 851.4000 is the Control Channel currently. My guess is Bellevue Hill, West Roxbury may be the only site so for that from the reception issues I'm seeing? Not really sure.
