Ok
1st Community EMS is not on either talk group (other then A714 and A747 who run Southgate downriver) its all HealthLink and Regional EMS which has a shared dispatch. Some genius decide that we would have separate TG's but in dispatch be patched together so the dispatcher does not have to listen to two radios, however, did poor patchwork.
12211 is HealthLink and 12209 is REMS. If you are listening to 12211 you will hear HL clear and REMS garbled, and opposite when listening to 12209. Yes, that is the same in our trucks.

The trucks and dispatch all have 800mHz trunked radios, the crappy quality is the poor patch work not a VHF patch.

redfordman38 has it right other than the dispatch situation. I can only speak for HL and REMS. We have the same dispatcher with separate TG's 12211 and 12209 brought together on one radio for the dispatcher, which creates a patch (or whatever you want to call it) onto the other TG that is very bad quality.

CEMS, DMCE, and BMTS all have TG's but are not yet operational.
We all have a dispatch TG and a secondary TG

For now CEMS is on there VHF with no simulcast to the MPSCS, or any 800mHz.
I believe the CEMS dispatch freq also has DMCE and BMTS on it as well, with one dispatcher

Community EMS (part owned by Botsford Hospital) is a part owner in all the "joint venture companies"
Oakwood Healthlink, DMC Express, Botsford Medical Transportation Service, Regional EMS, and even linked with companies in Texas and Florida

any other question let me know and ill try to find out

Wow great info, finally answered most of my questions. I guess Rob was wrong, there is a 24/7 patch.
But I still don't understand why the patch is needed at all if there's 2 talkgroups. Why do REMS rigs need to hear HL calls/rigs and vice versa? I understand them both needing to hear the dispatcher, but why is the patch needed? Why does the dispatcher need to be on both TGs at the same time?

When Fred says I was wrong, then I'll admit I was wrong...

I think Macari actually knows what he's talking about, he actually works for Health Link. Fred's a web designer and you're a TV weatherman who lives 60 miles away so why are you even on this thread?

I don't know Macari nor do I know his radio tech experience. I'm not saying he's wrong, but his story doesn't completely match up with what most people here know to be true. I can't see how a talkgroup patch can have issues. Most (all?) talkgroup patches are not physical connections that can be scratchy, but "computerized" for lack of a better term. That's all I'm saying.

(PS Fred is a little more than a "web designer" and I am a little more than a "TV weatherman." So watch who you're insulting when people are trying to help.)

I wasn't "insulting" either of you, I was just saying you don't seem to know what you're talking about. Yeah you got your ham tickets but you obviously don't know squat when it comes to complicated radio systems like the MPSCS. Also, you don't live in Flint, you can't monitor the talkgroups in question and you know nothing about the companies that use them. If you have more questions than answers when you read the original post, just move on to the next one and quit wasting everyone's time.

It has nothing to do with ham tickets either. Since I have had a MPSCS radio on my desk for nearly 10 years (not a scanner, a MPSCS radio,) and was the first person with a digital scanner for receiving MPSCS signals in the state, and have gone through MPSCS training from the state, I would just stop with the assumptions if I were you.

Whatever, you have been completely useless in this thread, you haven't answered a single thing I've asked, all you want to do is argue and contradict me and be a know it all, and ask 3 questions for every 1 that I ask.

And owning an MPSCS radio doesn't make you an expert on the system. Any Tom Dick or Harry can buy one on ebay for the right price.
Thats like watching House and then thinking you're ready to practice medicine.

Anyways, getting back on topic,Macari is 100% right about the audio quality. When HL rigs talk on 12209, it sounds terrible, almost like a weak AM broadcast station, its all garbled, buzzy and staticy. But when REMS rigs talk its crystal clear. Something was definitely screwed up when that patch was made and it has got to be fixed ASAP, or just deleted altogether.

Maybe its not a "patch", call it what you want. I do know for sure that on the Dispatch radio console it is on Dispatch CH 1.

The reason for having the two TG brought together is so the dispatcher can listen to one radio and we wont be talking over each other. Why we dont just all go to one TG or the other, no idea.

That is not true.

My guess would be that they are patched so one dispatcher can effectively dispatch all of the units. I don't know if you have any experience with public safety radio use (or anything similar) but it's awful hard to work with two different talkgroups at the same time. If they are patched then they won't divide the dispatcher's attention and step on each other.

Why they don't all just hop onto the same talkgroup and dump the patch...I'm not positive. MPSCS does restrict most talkgroups to a certain geographical area to save system resources and limit "system busy" problems. That could be what happened with these two talkgroups and they are trying to get around the problem by applying a patch, I doubt it though because the NCC would probably tell them to stop. Subpar equipment and incorrect patching could cause the audio quality problems.

I've gotta say Flintstone4680, you seem pretty worked up over this whole thing considering you have no stake in it other than listening in. Money is a huge roadblock in doing the MPSCS thing right plus they are out of room for now....

Well like I said its pretty annoying trying to listen to local EMS rigs when half the traffic is AM radio quality stuff from 2 counties over.

I think the posts about Fred this and Fred that, is referring to Flintstone, not you. But I could be sadly mistaken.

To simplify things in our database, would it be better if we grouped this all under "Botsford Health System?"

we have all complained about it. They will change it once the companies grow even more that 2 dispatchers are needed.
