21619 is Southeast Fireground 3

According to the DB here, it is.
MFC employees seem to disagree. See also my logs of 21617 (Fireground-4) and 21621 (Fireground-7).
Hard to believe the MSWIN is now going on 20 years old.
21617 is Southeast Fireground 2 and 21621 is Southeast Fireground 4. Someone is confused, don't know who.

The way I see it, there are two possibilities:
1- The RR database is out of date. Whomsoever originally obtained the information and submitted it either hasn't updated it, doesn't have current access, died, quit the hobby, etc.
2- The Mississippi Forestry Commission employees currently using their radios, looking at the channel name on the display and stating that channel name over the air when calling someone apparently have not been briefed that their radios are programmed wrong and should be referred to radioreference.

Option 3
A newbie submitted the info and has no idea what they are doing.

When we set up the system years ago, we put what info we had at the time from MSWIN radios, and submissions, and from direct monitoring back then. If you have more current info, submit it and the admins will fix it. This system is almost 20 years old now, and massive changes have happened, as happen to all systems over this much time.

Yes please do not complain about the system submit the correct information.

Who is complaining? The guy who is passing along the information he is hearing from the actual radio users or the guy saying he (and the system) are wrong and the database is definitive?
I guess slhbeard is right; I am confused.

Also, I am not submitting because 1) I rarely submit anything, and 2) I do not know anything more than the possibly partial name for the talkgroup.
Is 21621 Fireground-7 or is it Southeast Fireground-7? Wiggins Fireground-7? South Fireground-7? Statewide Firegound-7?

I show 21621 as Southeast Fireground 4. Someone who knows the correct answer should submit it. Now I'm confused.
MFC was reorganized in 2017, when the seven districts were consolidated into four regions. The database still shows the talkgroups organized according to the former seven-district structure, and it is unclear whether the radio system itself was updated to reflect the new organization.
The spring fire season would be a good opportunity to monitor MFC activity and confirm current talkgroup usage. It is good to discuss them here before rushing to update the database.
In my monitoring, MFC talkgroups have been somewhat difficult to map. I have heard crews refer to the same talkgroup using different fireground numbers. It can take extended monitoring to identify them with confidence.
TG 21621 was added to the database as Southeast Fireground 4 in November 2025, along with additions to other MFC districts. It appears that Firegrounds 3 and 4 were added to each of the districts. I can only assume these entries were based on confirmed information. The database listings follow a consistent structure across the districts.

I'm merely stating FTR what I'm hearing.
One MFC employee comes up on 21621 stating (not verbatim) "Bob, this is Jim on Fireground-7"
Bob replies "Jim, Bob, on 7, go ahead" Etc etc.
I would deduce that, at least somewhere, that 21621 is "Fireground-7".
It would take a codeplug read or similar to deduce the true name of 21621, be it SE FG-7, Region-4 FG-7, or even something as drilled down as Area-46 FG-7 (this was heard in Harrison County).

We have so many people that come here and say the database is wrong and complain and never submit new updates. I was not calling out anyone.
Yeah, that used to drive me insane. "Your wrong, that isn't what it is."... but then never submit anything. Or the others that subbed incorrect data on purpose. Moreso with the TACN, but with the MSWIN, I could literally be holding an HT, reading it with CPS, and get a sub that was completely wrong telling me I was the dumba**. If I was ever asked to be an admin again, I would have to think hard about it just from the sheer level of madness that got to be regular later on, and yes I finally started losing my cool. Once it went from a fun side of this hobby that I was enjoying, to being more like an actual 9 - 5 job but without benefits or real pay..... You know the rest of that story. Of course now I only have one contact left involved with the "deeper" side of MSWIN, the rest retired, quit, moved on to other places etc...

Yep; don't point a finger, lend a hand.

I logged MSWIN sites with DSD+ while driving along I-59 between Slidell and Meridian and came across an unlisted site.
The Rock Hill site (1.2) is reporting site 1.54 as a peer, with a control channel of 769.83125 MHz, which does not appear in the database.
I have seen previous references to sites 1.53 and 1.54 being associated with Camp Shelby, though neither site is listed in the DB.
769.83125 MHz is licensed at Camp Shelby (983 Lee Avenue West, Forrest County), which seems to line up with the observed neighbor site.
Has anyone confirmed the current site numbers, frequencies, NAC, etc for the Camp Shelby MSWIN sites?

AirEvac LifeTeam now has an MSWN talkgroup named AirEvac MS: 59574. They haven't switched over yet, but they are soon. AirEvac 87, 58, 99, 61 still use their VHF/WAVE repeater system. All helicopters have an MSWIN radio, but might not have the agency talkgroups or medcom, so the State EMS Net is still in use....if some still have a dual band MSWIN radio or VHF radio.
