KCMO P25 (MARRS) TRS -- PLEASE Post ALL questions/info here!!!

[blueangel-eric]

I can't get any reception tonight on the KCMO trunk. i am visiting the area and at my moms new apartment near Barry Rd and I29 i had radio traffic last night but since this morning i can't get anything. I'm using a PSR-500. i reuploaded my radio file and tried the Multi site mode off and on stationary. and CCs checked i can receive the data freq full strength. i tried the ATT off and on no change. i even put my 800mhz duck on. what's the problem?

If you are using multi-site Off or Roam:

Make sure 851.325 is in your control channel list.

It's possible that your radio is locking onto a control channel for a sub-system that doesn't carry the talk groups you are interested in.

Lets say your radio has locked onto 853.775 as it's control channel (Johnson county,KS). The chances are pretty good that you won't hear KCPD (MO) North Patrol....or just about any talk group on the Missouri side.

Check your control channel list, and temporarily remove any of the following frequencies if they exist:

853.77500 (Johnson County, KS)
858.93750 (Wyandotte County, KS)
857.73750 (East Jackson County, MO)
857.26250 (Platte County, MO)
851.10000 (Cass County, MO)

Many of the talk groups in that area are also carried on the Platte County sub-system.
If 851.32500 doesn't work for you, try 857.26250

I have the Johnson County and KCMO in seperate banks. i have 851.050000, 851.325000, 851.600000, 851.862500 programmed in for KCMO. i took out the trunking tables because i wasn't sure if they were wrong but i don't think it helped much. the database page doesn't list what they are so i don't know what to do for all the trunk systems using Win500. i notice it's like that on RR that the trunking tables are never listed.

 

[blueangel-eric]

anyone? I have been playing with this the last 3 nights and i'm going home tomorrow so this is my last night to listen. i've been listening all this time and hearing nothing absolutely nothing.

Double check everything, and be sure you have 851.325 in it. 851.325 is the current control channel. I'm unfamiliar with a PSR-500, but Talkpair knows his stuff. From I-29 and Barry Road your scanner should decode the North Zone site pretty well.

Sorry I'm not too much help, but that's all I know. I was decoding the system yesterday just fine with my Unidens.

i've double and rechecked everything but i don't know what else i could be missing. no one has said anything about whether or not i have to add the trunking tables and i searched the forum to no avail and the wiki or database doesn't say anything about it. i just hooked my cable up and started monitoring/ controlling, via the Win500 and it works but as soon as i click stop on the software the audio drops out after 2 seconds and the scanner starts scanning endlessly forever in the middle of a transmission. i click start and then it starts receiving again. i can't figure this out.

I also want to mention I have been in KC quite a few times since the new system was online and my programming received everything just fine as it could considering the new system setup. i could monitor both KCMO and Johnson CO. it worked fine a few nights ago for many hours then i went to sleep and woke up with it not working anymore.

update: I downloaded back to the software and then checked the trunk tables and they were automatically filled in and then reuploaded and now it works fine as far as i can tell. i just can't receive the MOSWIN from here so i don't have anything for the trunk tables.

update: now it's crapping out again unless the radio traffic is quiet. not sure how many minutes up here it would be quiet though.

You do not need custom (trunking) tables for MARRS or MOSWIN in the Kansas City area.
Set your Trunking System Type to P25 Auto, and the radio will take care of the table.

Thanks for the info. i re uploaded again but with Multi-site and stationary back on and it worked again. does roam or stationary have to be on for it to work?

There are 3 options for Multisite........Off, Roam, and Stat (Stationary)

If you are using a single TSYS object for both Johnson county, KS and Kansas City, MO subsystems, you must use the Stat option in order for the scanner to check more than one control channel.
Make sure both control channels are in the frequency list.
The Stat option scans all usable control channels in the frequency list, which makes the combined subsystems appear as a single site. This relieves the programmer from knowing which subsystem carries the desired talk group.

If you are using a separate TSYS object for Johnson county and KCMO, use the Multi-Site:Off option.
With this setting, make sure you keep control channels from other subsystems off of your frequency list or you run the risk of the scanner using the control channel of another subsystem which may not carry the talk groups you want.

I cant think of a scenario where using Roam for MARRS would be useful.

I personally prefer having separate TSYS objects for the various subsystems with Multi-Site turned off.
This way if I lock out all the talk groups carried by a given subsystem, that control channel is no longer scanned which frees up valuable time.
When using the Stat option, all of the control channels are still scanned even if only a single talk group is enabled. If you are going to use this option, enter the bare minimum number of control channels, as scanning control channels unnecessarily will bring your scanner to a crawl.

Are KCPD radios set to roam throughout the network so that their radios truly work across the entire MARRS network?

For example, a couple nights ago there was a great pursuit of an armed robbery suspect. The pursuit actually started in or near Columbia, Mo and came to KC. An East zone Officer picked up the pursuit and as they traveled NW and started to come up I-29 I suddenly heard them on the Platte County tower (that's the only one I can hear at my location so when a pursuit came on and the scanner said KCPD East, I was like WOW! and cranked up the volume!).

So that's the background for my question: are KCPD radios set to roam throughout the entire MARRS region?

Incidentally, the pursuit continued north on I-29 at speeds of 105+. KCPD Helicopter 690 finally had to turn back once they were somewhere well north of St Joe because they were low on fuel and all of the agencies involved eventually lost radio contact because they were so far north. Some officers were in contact with their dispatchers via cell phone and the driver finally hit stop sticks somewhere in Holt County and was taken into custody.

It was interesting that Platte County and KCPD ran out of radio contact as well as Mo Highway Patrol on the MoSWIN system. The MHP dispatcher even knew and was warning the troopers involved that at about St Joe radio coverage would be lost and the dispatcher was right. I would think that if anyone's radio roamed it would be the State Troopers.

Anyway, sorry for my rambling. Perhaps I'm not understanding the roam feature.

They can certainly roam on any of the regional common and east common groups. If I'm not mistaken, they can also roam to other tower sites and talk directly to several outside agencies on their dispatch talkgroups (Platte County Law-1 or Leawood, KS PD just as a couple of examples).

Is it possible that they were reaching the limit of what the MARRS towers cover? As far as I know (please correct me if I am wrong), the MARRS and MoSWIN controllers have not been networked together- though it has been discussed. So, once units operating on MARRS reached a certain point, they would have to manually switch to MoSWIN- if they could. I say if they could as I didn't think that KCMO installed the dual band VHF/800 digital trunking radios in their cars they would need to operate on MoSWIN even if the systems were networked and the cars could roam.

 

[scannerowner]

St. Joe seems to be a dead zone for MOSWIN. I'm surprised they won't tie-in Buchanan County with Platte County so coverage works well all around.

MARRS and MOSWIN were connected via ISSI (Inter-RF Subsystem Interface) over the summer when Motorola completed the 7.14 software upgrades.

So, did KCMO install the MoSWIN capable dual band radios? If not, do their cars simply go out of range when they his the VHF tower coverage?

Not sure how that works with the "guts" of the system, but nothing changed as far as end user radios. MOSWIN users can now talk on MARRS easier and vice versa.

This should provide a better explanation than I can probably give you:

[JRsTheMAN]

Can someone message me what I need to do to be able to receive MARRS with my homepatrol I. Or at least reply in the thread.

 

[KCoax]

Main Menu. Set location. Enter A MARRS zip. Go Manage Favorites List. Select Database to Monitor. Choose Only Full Database. Main Menu. Select Service Types to listen too. Once the scanner is delayed on Kansas City Metro - Metroplitan Area Regi... Press the screen (turns yellow) to hold on. While held on MARRS. You can select JOCO, KCMO, EAST JACO, Platte CO... Towers. Press the arrow to the right of the yellow highlighted area. Select Advanced. Select Sites to avoid.

Thank you KCoax!

MOSWIN/MARRS link

"Not sure how that works with the "guts" of the system, but nothing changed as far as end user radios. MOSWIN users can now talk on MARRS easier and vice versa."

Not quite correct......

MOSWIN users still talk on their system, but the MOSWIN system has talkgoups is linked to MARRS. If MOSWIN user drives out of MOSWIN radio coverage, they are not able to "talk on" MARRS. Same if MARRS user drives out of coverage, they are not able to talk to MOSWIN. Radios are still on different bands

This is how it's been explained to me..... I assume if that's incorrect, someone will chime in....
