MPSCS Skip??

[gg750]

I'm trying to pull into consideration the point that the OP ran Pro96com and didn't see any "oddball" affiliations on the tower at the time they were hearing the distant department traffic.

Thats kinda where I was going with it. Shortly after the original post, TG 7050 (Marquette County Sheriff) started coming through. Doing another check on Pro96Com didn't show any radios with a county ID of 52 (the second 2 numbers on the radio code, right?) showing up, nor any affiliations with that TG on the tower at all, yet I'm still hearing it. Same goes for some of the other talk groups. However, later that evening, I did see an affiliation for TG 2313 with a Macomb county radio ID, but that was the only one.

Whatever the reason, it made for some interesting listening last night. A few times I forgot about the out-of-town traffic coming through and started to wonder what the hell was going on around here.

If it were a control channel skip - he wouldn't have heard the audio. And it certainly wouldn't have been happening all day long for two days now.

Again - we can theorize about a boatload of options. But given 1) there's a conference here with MANY MANY non-TC units in place 2) this is a statewide system, and many agencies have their home talkgroups go out of the home+1 county area that 3) this is just a feature of said agencies and their units.

Because you didn't see the affiliation doesn't mean it didn't happen. If you weren't running Pro96Com when they came into the county, you missed it. Radios don't continually reaffiliate unless turned off/on or the talkgroup is changed, neither of which would be happening much.

Plus many of these radios are EM users and not necessarily PD units, so might have different radio ID numbers than you are used to.

How about this - my theory is that you'll stop hearing these after Wednesday night. If that's the case, can we confirm m297 & me as correct

1002 - I hear Livingston Co quite often on the Grayling and Waters towers and have seen a LivCo car up there in the past. I don't think it's a coincidence either...

[/QUOTE=MetroMike;900163]Okay, so basically an MSP unit that works, say Alcona County, will be able to monitor 01P911 both inside and outside of the rings whereas as county unit with no need to leave the county lines would be restricted to the first "ring" or two? Even if both were programmed with the same centralized dispatch talkgroup?[/QUOTE]

I would say this is a fair discription. For radio that do not need to leave their "home" are will not work past the designated area (1/2 counties). If you were talking command staff or a state responder, they could, and probably do, have the whole state. It is up to the agency and approval of MPSCS. If all radios were able to travel outside of their designated area, the towers would be full of traffic.

I would assume, and maybe someone can confirm or correct me on this, that command staff in Detroit would have the ability to monitor outside the city limits where the common users are not able to go much outside the city.

Reread the info I posted from the MPSCS training materials...the TALKGROUP ID is the limiting factor for roaming/site access profiles...NOT individual radio IDs. It doesn't matter who's radio the talkgroup is on...either it (the talkgroup) is allowed on remote towers or it isn't. Like M297 said, his Zone C talkgroups are setup as I've described. Presumably, their Zone A and/or B talkgroups are allowed to affiliate statewide.

On our radios, our zone A is Detroit's talkgroups. Zones B, C, D and J are our talkgroups. Anything in Zone A is limited to the Detroit simulcast towers (even for us). Zones B, C, D and J are countywide and extend across most of the adjacent counties, plus the Lansing tower (101). Anything in Zones E, F (not MPSCS), G, H or I work statewide (standard template for all LE MPSCS radios).

Some of your "A" must be Lansing too as I've heard Detroit Fire Dispatch at times.

You know I read this but it didn't sink in. Ok, I was under the impression that it was radio dependent. I have learned something new today. Thanks for the info.

I've transported my XTS2500 up to Cadillac and to Harbor Springs this past summer. I could monitor my local TG's with no problem. My department main and a court related TG.

However, occasionally the prep would go, uh.... "stupid" and would have no traffic for an abnormally long period. I'd key up and be able to both monitor and transmit again. On any of my local TG's.

I don't remember if I had to transmit on each of my local TG's that I use to "re-enable" them or not. Will have to remember to check that during the next trip up north.

Any change since Wednesday?

Kimball Twp FD is known for screaming into their radios. I'm suprised Central hasn't cut them off completely for blowing their ear drums apart.



I know a Macomb Co. S.O. car was in Alpena a year ago and they were on 50P911 and they were able to scan their local talkgroups and key up and talk back to Sheriff Dispatch in Clinton Township...

They WEREN'T on a state wide tg either.

Not to mention 2 years ago at the Homeland Security Conference alot of the cops and firemen were on their home tg's and they had to tell them to go to a statewide tg becuase the towers were getting overloaded in the G.R. area. One of the members here on the forum was there and he said the same thing to me...

 

[hughes369]

Rdale -

Don't know if there's been a change. No scheduled travel out of my county for a while. Will let you know.

 

[rdale]

Sorry - I meant for gg. If our theory was correct, he stopped hearing all the out-of-area talkgroups after the conference ended Wednesday...

 

[Hoofy]

Don't forget the MPSCS radio techs. I believe they have access to lots of tg's.


I went round and round about this 800 skip thing many months ago and discovered that it was probably our local MPSCS radio tech. playing around with different tg's on his radio that was allowing me to hear all the strange traffic coming in to our very remote area.

He must visit this forum because since that time I have heard very little that I can't explain locally.

 

[Skud]

I do have to say I have been able to pick up towers 80 miles away, depending on where I am in my house. Ones I have never in 4 year been able to pick up and it has been for about the last month or so.

Yup, MPSCS here in TC went back to normal...dead quiet.

On the MPSCS MSP District 7 West Dispatch (TG ID 4035) is active down in SE Lower Michigan as of 10/15/08 @ 10am. Its kind of weird to hearing the units talking about lake city, T.C., etc...

 

[rdale]

It's not skip

 

[djmusic1666]

It's not skip

ok then if it ant skip r dale what is it then if i can ask . cause i hear it from time to time granted tho

iam not too far from the post 70 area tho .:roll:

 

[fnnm1062]

i didnt say it was skip, i was just merely posting here, rather than start a new topic. I just wanted to pass on what I was hearing, for others.

I know what both sides are saying and I can see both points of view, is it or is it not skip. I am leaning myself towards it must be due to a unit from that area down this way, maybe even on a warrant pick up, but regardless, it is neat to hear the info from up there down here.

 

[rdale]

I was joking. Most of us here realize it's not skip.
