COMIRS Question

#1 Post by dimaxxxl » 09 Feb 2020 10:46

Hello all,
New member to this forum. Has anyone heard state police activity on the Massachusetts COMERS SYSTEM. I listened to it for a few hours last night and heard only Boston Fire, Boston citywide 3/4 and a few transmissions from troop F and mass port. Has anyone heard any of the other mass state police troops on COMIRS?

Hello.

Welcome to Scan New England. I am going to direct you to the wiki, the CoMIRS page, where you can see we list all TGs with a confirmation of last use.
This will tell you when we've last heard PD activity on the CoMIRS trunk.

https://scan-ne.net/wiki/index.php?titl ... Project_25

As you can see, for the Boston area, there isn't much use on it by State Police, However in Western Mass, there is quite a bit, as it's the primary for Berkshire County and the non-91 corridor.

to add to what Mike mentioned, what Zone/Site were you listening to ??

I am going to guess the 700 Overlay, which will have little to none, for the MSP
Eastern Mass State Police [outside of Massport] is pretty much on the 0D14 Analog system not the D14 P25 System

If within Rte-128/95 and 495 rely on Zone/Site 5 for the MSP

Thank you for all the info. I was listening to the 700 overlay I believe. I have been a scanner enthusiast for about 20 years now but still a beginner outside of listening and basic programming. I appreciate all the insight I have found on this board.

The plan has always been for the 700 Mhz system to be for non MSP users. There is a fair amount of MassPort P25 traffic on it as well as MassPort has a lot of property along the South Boston waterfront and sometimes units there can't hit the MassPort system. As Bil points out, you'll hear Troop F, MassPort Fire, MassPort Police for the most part on the 700 system. You'll also hear a lot of City of Boston agencies as well.

Are the state police going to go all digital eventually?

Yes.
when ? Funding and build-out timeframes will vary

IMHO - look for a West to East approach

Hi, is there any where that I could download a coverage map of the overlay 700 system? When I'm roaming around, I could put on that bank if in the coverage area.
And since I'm here, what does COMIRS mean?

Thanks,
J.

Since it is transmitting from 8 sites, being
Arlington, Boston 4 Sites, Milton, Quincy, Revere

Plan your coverage based on that, the RR projected Map is much much too big to rely on for 700 coverage
you could almost say, Rte-128 [if Revere covers up into Peabody]

since it is transmitting from

See Page 3 of this report to the FCC https://wireless2.fcc.gov/UlsEntry/atta ... applAttach (shoutout ScanBoston for finding this)

As other have said, essentially inside 128, a bit more to the south a bit less to the north.
