How did you obtain that info if there hasn't been activity on the talkgroups yet as well as encrypted ones?
A look on Calls Platform doesn't show activity on most of those TG's yet.

A user on here many years ago posted a talkgroup layout plan for MSP that they created and so far it has always been accurate for talkgroups once the Barracks switch over on FiRST. I can't remember the user but saved the info.

I found the link in the wiki that the user Dpcain created.

Question…first time monitoring a new FIRST zone coming online. Are they not yet broadcasting to neighbor sites? I heard a ton when I was in PG today, also heard some in Charles but they don’t seem to be broadcasting to each other as neighbors.

Thanks in advance for answering the newbie question.

7347 MSP Q College Park patch active.
Hopefully they'll get a separate TG. Right now they're sharing with MSP L Forestville on the county system. It's hard to hear MSP in this county due to county police activity unless you block them out (and there ain't no way that is happening 😎)

Nice Bridge is simulcasting on 7104 MdTAP ICC, I wonder why they are not using 7107 MdTAP NiceBr ?
I'm beginning to think 7104 not the ICC talk group, and 7107 is not the Nice Bridge tg.

Generally, a call would be heard on the sites bordering (aka "Neighbor" or "Peer") the site where a field unit on the same talk group is affiliated. Can you provide a specific example?

example: I should be able to hear UMD College Park while monitoring Charles County simulcast. correct?

Yes. I heard UMCP Police today on the Charles site.

What radio are you using? You should only need the two control channels.
SDS100. I was missing the second control channel. I didn’t think to check it earlier because I had just updated with Sentinel but I guess it missed it. I’m currently picking up traffic on the Charles site now.

I noticed that somebody requested channels to be removed from the St. Mary's site. Please understand that you may not see all channels assigned to that site immediately, with more to be detected as the site gets busier and accesses them. The channels removed (770.65625 and 773.03125) are coordinated to be used on the site and have been on-the-air during testing. Be patient and be sure before submitting a change ticket.

Note that there will be 6 channels each for the Nice Bridge and Bethune ASRs, and 6 channels for the St. Mary's, Calvert, and Charles cells.
