Lately, a lot of new talkgroups have been popping up on the Flat Rock, Monroe and Washtenaw County simulcast systems. However, they are not showing up on the Northville or Southfield sites. The talkgroups are:


  • 12777
  • 12779
  • 12780
  • 12781
  • 12782
  • 12783
  • 12784
  • 12785
  • 12786
RIDs that been observed so far are 8282412 and 8282420. Anyone have a clue as to whom this might be?

I understand that all preps in Monroe Co are going in for a new template, so they may just be testing those now.

That is possible, but I haven't seen any of these new radio affiliating with Monroe County's fire or police talkgroups. They have however, been affiliating with Huron Twp. Fire Disp. and Washtenaw County's fireground interop talkgroups. Also, the helicopter landing zone talkgroups have popped up from time-to-time. This makes me suspect that it is a fire department in Wayne County.

Sorry for not clarifying - I don't think Monroe Co is changing anything. It's probably in some of their mutual aid / helo / or MSP settings?

Tg 1804

Every morning I hear units checking in for service (rig, PC, etc). like I hear when MMR units check in on 1804. Radio ID is for Iosco county. Does MMR operate there?

Heard a unit called "Victor 2" checking in. Also saw a Saginaw radio ID in addition to Iosco. Anyone in that area able to confirm this as Iosco MMR?

MPSCS Frequency Changes

MPSCS Frequency Changes

It should be noted that there are several sites that have incorrect frequencies assigned in the rr.com database. For example; when the seven-site Washtenaw County Simulcast system was created, they took several channels from surrounding sites and incorporated them into the simulcast system but at the new tower locations.

I have submitted these updates; but whomever it managing these changes is making a command decision to ignore the information provided and simply uses the information from the FCC License Database; which is generally several months behind the changes.

Any ideas of how we overcome this issue? I am a database admin; however, I do not have access to the MPSCS system; just the southeast counties of the state.

Examples of frequencies taken from other towers are as follows:

Howell (Site 217) - No longer has 868.2500, this has been moved to the Washtenaw County Simulcast system.

Munith (Site 105) - Several frequencies have been moved into the Washtenaw County Simulcast system.

Holly (Site 201) - Several frequencies have been moved into the Washtenaw County Simulcast system.

I will resubmit these changes once again to see what happens; but I think updates need to be run throughout the state as many control channels have changed as well as the actual site frequencies. I have confirmed this on at least five sites so far over the past month. Those sites are 104, 105, 201, 217, & 222.

Send these updates to me, I will make sure that the database is updated accordingly. I know that with the major rebanding project that is getting underway, there are going to be substantial changes to the frequency listings at all of the tower sites over the coming year. Sadly, we rarely receive any information from Northern Lower Peninsula and Upper Peninsula of Michigan. So we often have to go by information that is rarely updated from those areas.

All of the simulcast systems on the MPSCS, have the ability to use the "Dynamic Sharing Arrangement" (Hereafter: DSA) feature. This means that if all of the frequency pairs are in use at one site, it will borrow one or two frequency pairs from a neighboring site. Conversely, stand-alone towers can also borrow frequency pairs from simulcast systems. This has been very commonplace in the Metro Detroit area.

For instance, the Washtenaw County Simulcast System is fully loaded and a public safety unit keys up at a major fire scene in Northfield Twp. on one of the Interop talkgroups, but all of the frequency pairs are in use. The site controller will check with all of its neighboring sites, and take a pair that is not in use. In this case one pair from the nearby Northville site so the transmission would be relayed to the other units on the Washtenaw County Simulcast System. If the heavy traffic continues, one of the next transmissions could take place on a frequency pair normally assigned to the Adrian, Howell, or Munith towers thanks to the DSA programming.

The database was updated with this information for the benefit of Uniden Scanner owners. In the past, we would receive complaints about missed radio transmissions during peak times on the MPSCS. It was decided to include frequency pairs that are often used in the DSA plan at each site. Thankfully, GRE and Radio Shack scanners don't miss radio transmissions when the DSA feature activates.

Ron,

No problem and I fully understand. As I travel the state, I catalog all the sites current information and compare it to previous database versions, as well as create a Google Earth Map with all the tower locations as well as their respective coverage areas and to-whom they are sister sites too (just makes scanning easier around the state).

I will resubmit these updates over the next few days. As for the Uniden scanners, I am not sure why they are missing transmissions. All of the Uniden Digital Scanners since the BC296/796 and above, have been able to track the systems via control channel mode and therefore should NOT need the additional frequencies added. By adding too many frequencies, it can actually slow down tracking and can confuse the scanner if a digital burst comes through on a voice channel. All users should be configured for "control channel only" mode and thus only programming these channels.

Another thing I've noticed is that some sites have four control channels assigned; one primary and three alternates. In the 7.9x platform, there should only be two, one primary and one secondary. According to MPSCS news, all the southeastern Michigan sites should have already been through these updates if not the who state already. The sites I will be submitting already contain this information as well.

If you'd like to compare notes, ideas, etc. please feel free to contact me directly via PM or e-mail.

Thanks,

Jerry

Actually RR does not list the Roseville and East Point Police Dispatch talk group but I was able to determine that both communities share the 2879 talk group and still identify Roseville units as 70 cars and East Point cars as 30 units, as they did years ago when they shared a 460.5000 Mhz repeater.


Actually it does they all are under SERESA (Southeast Emergency Service Authority) The dispatch center is at the old senior place
SERESA: 18961 Common Rd, Roseville, MI. 48066

It includes Eastpointe, Roseville, and Saint Clair Shores.

2875 TG St. Clair Shores PD Dispatch
2877 TG Eastpointe PD Dispatch
2879 TG Roseville PD Dispatch
12566 TG Detective Bureau which is encrypted and includes all three cities

Then you have SERESA Fire TG 12619 which inlcudes all cities above.

The reason I know this is because my 9-1-1 Telecommuncations Two teacher that I had is the Director of the SERESA Dispatch Center.

The one city they were hoping to get on board was Clinton Township, but one of the reasons Clinton did not join is because they would be using two different cad systems.

I have pictures on here somewhere posted of the dispatch center. I believe.


Here you go heres a link to it. http://forums.radioreference.com/michigan-radio-discussion-forum/211532-seresa-dispatch-pics.html

TG13071 is 08MERCY1 but I have no idea where. Unit 338 was calling dispatch saying they were leaving and heading back to Hastings station. I don't know enough about Barry Co to know if that's there...

Mercy Ambulance Service, covers Barry and Clinton Counties. They are apparently moving their communications onto the MPSCS. I suspect more talkgroups will pop-up in the coming months.

hmm I will check this out. Mercy is still being dispatched thru Barry County Central Dispatch.
The TG could just be Mercy's own dispatch freqTG which is seperate from Mercy in Barry County.

Skud - I never heard any dispatches. Just sort of admin-type chatter. You are probably correct in the need to change this designation (at least for now.) Given the "08" designation, it must be Barry Co specific.

What tower was it off of? Where I am at I cannot get the Nashville tower and most times Hastings city are will hit that tower. I am only getting the Allegan tower so if they head west I will get them. I wonder if they will only be Mercy HQ or if Central with Dispatch them. I will add that TG to my list.
