MOSWIN STL area

[llzel]

The only MOSWIN tower I have programmed in my Unication G4 is St Louis Simulcast (previous north) 2 site 1. On one knob I have MSHP trp C dispatch 1,2 & 3. Also Region C Law 1, 2, & 3. Last night I was getting a lot of chatter on dispatch 1. Actually I heard the dispatcher tell a car that they will be on dispatch 1 all night. More chatter than normal. Also heard Conservation 512 call in several plates and individuals from bunker 1 in St Charles. I don't have St Louis City/MSHP 2 site 5 programmed. Was I getting activity with troop C perhaps because there was a car linked to St Louis City Simulcast tower?
Also Reg C Law 1 was very active with a helicopter following a car from Jefferson county to north city where they lost the target car.
Today, I'm getting chatter on dispatch 2 mostly with some on 1.
I'm curious if I should program in St Louis City/HSHP site 5 in and get more chatter? The reason I ask is that there are days I will get nothing on troop C for hours.

That's a possibility since it was a simulcast tower site.

 

[StevenHuffman1224]

And I would definitely program St Louis City/HSHP site 5 in.

I am not sure how the Unication radios work but I would ask where are you located. You could hear MSHP on about 3 sites in the StL area and a couple more if you add a couple Metro [bus/train] sites.

What channels they use is less important than the sites the cars affiliated with. You could potentially hear cars as far north as Lincoln Co or as far south as St Genevieve Co.

Troop C can sometimes be slow other times very busy. Sites 201, 327 and 316(or 319) should get you about 90% of all Troop C traffic. But again I don't know the limits of the Unication programming.

And I must add, you need to be in receiving range of those sites to monitor them. Too far west in St Charles Co then you won't hear the city sites or the JeffCo site.

I'm in mid county University City. My Unication is only 700/800 so 327 and 316 is out of the question. I added 205 yesterday and troop C was very quiet or no cars affiliated with 201 or 205. I didn't think about adding the metro towers maybe I will and lambert too.
Unications aren't really a scanner but more radio. One knob position can only have one system. 8 knob positions. So Knob 1 I have MOSWIN STLFD/EMS, Knob 2 SLATER east central and U City, Knob 3 Slater Central County 911 south, and Knob 4 Central county 911 North, and so on. You can't have SLATER and MOSWIN on the same knob position.

The other thing to keep in mind wotu uncation and you may know this…even if you have multiple sites on one system the unications lock onto the strongest signal. Also not 10”% sure if the metro transit ajd lambert would have MAHP affliction on them. I k ow in other states where other agencies are on the statewide systems state police don’t have affiliation privileges.

 

[KA0KDW]

I’ve never watched the metro transit or lambert sites while up there so I don’t know of MSHP has been on there or not.

 

[nick1427d]

MSHP affiliates to the METRO sites. Most of the MOSWIN Region C talk groups do including St. Louis city talkgroups. I’ve monitored city fire from a METRO sites and I don’t seem to miss much. Highway patrol is hit or miss.

So are you referring to Metro Transit Simulcast sites or St Louis City Simulcast site. I have the St Louis City Simulcast site 2-1 and St Louis MSHP site 2-5 programed. I hear MSHP on St Louis City Simulcast 2-1 tower and never on 2-5. If 1 MSHP car affiliates to the city tower does that me I should hear all MSHP traffic?

 

[scanman1958]

As some people would say...it's complicated. You can hear MSHP on some of the METRO sites. I think they are numberd 206, 207 and 208. The radio techs ( I belive) program the radios to only affiliate with certain sites. If a signal from a car is a little weak on site 201 for the city north site then a possible METRO site can can pick up the signal. The Imperial site could be too far to work. And yes I believe the MSHP does not affiliate with site 205 the city south site. If you keep in mind the way cell phone towers work it may make it easier to understand how MOSWIN sites work. You will learn it eventually. It is difficult.

My thought was that if a car was affiliated with north tower 201 than that car would be able to receive all trp C broadcasts, and such we scanner folks would. I understand that the car leave the north 201 tower and jumps on to weldon springs tower the north loses broadcasts and frees up those frequencies and I can't hear trp C until another car affiliates. I'll program Metro 3 sites in. Strange thing is Metro broadcasts on the 201 north tower.

 

[nick1427d]

The radios are programmed to “work” on all sites. All state MOSWIN control channels are in the radio. Nothing in the radio says what talkgroups go to what site. There are “preferred” sites within the radio but the radio will find the best signal anyway.

The sites themselves or zone controllers determine what TGs are allowed or not. If you watch various systems you will see radios get “denied” this is usually because they’re sitting on a TG that they don’t want affiliating to a particular site so the brains of the system says no. This is all set up so the frequencies don’t get tied up all over the state. The real selling point for trunking is efficient frequency usage not interop….

The radio can only be on one Talkgroup at a time so if it’s sitting on Dispatch 1 or whatever then yes it will receive Dispatch 1 traffic regardless of the site it’s on. If it can’t work on that site for whatever reason, the radio will go out of range and not work until that radio gets within range of another site allowing that talkgroup.
