LATIE System Updates

[loumaag]

While spending a few days in the New Orleans area on family matters, I did some Pro96Com investigation of the LATIE system in the NOLA area and along I-10 heading back to Houston. Based on that information I have updated the LATIE System page here in the database. While doing that I also got some talk group information but was unable to positively identify any of them. I will say that I did not hear/log any of the TG ID's that are in the DB at this time. Just generally based on what I heard I would venture to guess that the series of TG's in the 27000 range probably belong to Plaquemines Parish, but if someone that lives in the area could get to monitoring then they could confirm them.

The following are the TG ID's logged by the Pro96Com software, the majority of them were logged from the 101 site.

What is needed now is more monitoring and site identification along with capturing/identifying more voice frequencies.

 

[ke5lvt]

the first baton rouge LATIE site is at tiger statium. the antennas are mounted on 2 light poles at the top. there are 1 to 2 more sites being planed right now. will advise asap.

hello there,

I have found two more 700 numbers that go two the new orleans list that is list at the top of the database and there are data channels to be monitored ,i will list these two for the group 755.087,755.100 and the talk group ids were matching up with the ones that new orleans hasat the top ,kind of funny Well got to let lou know ....

Something else how come when you put 700 numbers in all for except st bernard why is it that plaqamenss parish id keeps showing up is this the only two working right now..

 

[butch1893]

Right now St. Bernard and Plaquemines Sheriff's Office and some of the Plaq. Govt. are on the 700. I am getting an ID 41686 that I do not know.

I am not sure what you meant by "plaqamenss parish id" (sic), but if you mean the system ID 1bd, that is the LATIE system ID and has nothing to do with where you are hearing it. Also, the frequencies you listed are invalid, the band does not extend to the 755 MHz area.

The frequencies listed by site numbers 900 and above are those that were initially put in the database and I fear were based on poor information. Despite the fact that the various parishes have 700 MHz licenses issued to them, the only license I see as being used is the state license which covers the whole band. Hence, as I said previously, don't bother to use the FCC database as a source of information on this system.

Those of you using the BCD396T (the only scanner presently out that can monitor this system) remember that it does not resolve to the proper decimal point on the frequencies. If you submit any frequencies based on what you find with the 396T, just submit what you see, plugging the frequency in a Pro-96 or 2096 will result in the proper frequency being displayed and will be used for updates.

they way i wrote it did not come out right ,but lets say this say if ya did not have a pro 96 ok,and you just had the 396 ok,now if you do a custum search of what is listed or even if you did not look aat the list and it was a random thing ok,and if you search such and such from point A to point B you pick up different control channels thats not list ,But what i did was i took like new orleans i programed it into the 396 ok ,its not picking new orleans its picking up another place like palqamens ids and not new orleans ids that what i was trying to say ,and i,m sure other people see this too But till we actually know the facts ,i might have to invest in a pro 96 and do what you did and listed it ,infact i like how you did it .Andfurther more like you said do not count on whats on the db and i will say you are right and i will say that propbly what i did ,And also say that i made a mistake so please FORGIVE me lou

 

[loumaag]

Please understand, I am not saying that the BCD396T is not good for researching the LATIE system. As a matter of fact, it was the starting point for me. First I used a set of three custom searches to find CCh's then used my Pro-96 and the software to do extensive research on the ones I could set up. In that regard, I had used the BCD396T on my way into the NOLA area (while driving) to note found CCh's and tower (site) numbers on the system. Once in town, I then used the computer and Pro-96 to do more research.

For those of you who want to try and do searches with your BCD396T's here are the settings I used to set up as custom searches, it requires 3 separate searches to cover the the 700 MHz Public Safety Band:

On all three of these the following were common settings:
Delay 2 secs; Hold 0 Secs; Attenuation Off; Data Skip Off; CCh Only On; P25 Auto
Settings:
#1 -- 764.0000 thru 767.000; step 6.25k; NFM
#2 -- 773.0000 thru 775.9875*; step 6.25k; NFM
#3 -- 767.0000 thru 773.0000; step 50k; FM

* For some reason the scanner will not accept 776.0000 as an upper value and the closest I could set was 775.9875.

When using these settings and doing a "Custom Search Only", the scanner will find and stop on valid control channels. When it does, press <Hold> and the scanner will stay there and monitor the CCh. It will provide the System ID (should show "01bdh" on screen)and the Tower number and it will also operate like it was in ID Search mode going to voice channels with conversations. This gives you the opportunity to note the voice channels. I included the wide FM part of the band (#3) although I don't think any trunking activity will take place in that part of the band. It might be better to occasionally look at that segment in standard (not control channel only) mode to see if there are any interesting things there.

...i might have to invest in a pro 96 and do what you did ...

In going over this thread again, I just noticed that statement. $500 is a lot of money to lay out if you are not going to get much out of it. Remember, the Pro-96/2096 cannot monitor the LATIE system. It can receive the frequencies, but it cannot trunk track in the 700 MHz band. The only radio on the market that can actually monitor the LATIE right now is the BCD396T.

Well i got the 396 thats why i was aking about how to track it,but for as the 96 i wanted to see ,if it could receive it ,and make a table of what it picks up but since you explained it on the 396 not further in doing that ,because i,m following the steps you had put on the screen and thats been a great help since then,and i want to thank you in that matter.

How to put 700 mhz in pro-2096?

A newbie here. I just got my 2096 back from the shack after the audio amp was knocked out by lightning? The Shack was great 7 days to replace part and under warranty, thanks to Radio Shack. I have been reading the Latie threads and wanted to try to help with monitoring in the Slidell area. I have a discone up about 30' so can get N.O. pretty well. I tried to tune to some of the 700 mhz freqs but get invalid freq. displayed. Tried Win96 by putting in an upper and lower freq for a search. It uploads ok but starts searching about 808.00 mhz. Looked in the 2096 manual and it seems to say that it skips from 512 mhz to 808 mhz. I ran out of time last night but will try entering latie CCHs in a bank to see if that works. Any help would be appreciated. I can hear the CCH for Jeff & St. Bernard on my AOR 8200 but it doesn't display the kind of info Lou is looking for. Sorry so long winded, my first post. I have downloaded Pro96Com and it connects to the 2096 but I don't know what else to do with it.

Dave

 

[loumaag]

Dave,

You need to use the Win96 software from Don Starr and enable the extended frequencies to get to the 700 MHz range. You can find that on the first tab on software. If you have not used the software before, be sure do download the setup in your radio to begin with before writing to the radio. The software can be used for a free trial for 30 days but well worth the $30 it costs to register. However, if all you want to do is extend the frequencies, you could do that with the trial version and as long as you never reset the radio, they will remain enabled for hand programming.

Win96 can be found at: http://www.starrsoft.com

 

[dlively]

Thank you Lou, I have been using Win96 and think its great. I have been able to program banks for railroads, aircraft, slidell police etc. with it. I wasn't aware of the extended freq checkbox. I can now set the 700 mhz ranges you mentioned in the limit search both in win96 and manually. I just did a scan and hear some sort of control channel on 775.09375 that is strong enough that I can't squelch it out. I tried Pro96Com and it indicated in receive rate 100% and (1 out of 1) (2 out of 2) etc. but nothing shows up in the screens. It has some instructions in the bottom right but only the top of the text is showing and I can't read it. If I can learn how to do this I would like to help ferret out the Latie info and maybe get a BC996 or something if its going to track Latie.

Dave,

Okay, obviously you are having a screen size issue. Not sure how you can see the decode rate but not see the instructions though... In any case, slide over to the yahoo groups and join the PRO96COM yahoo group. Mike (who wrote the software) is the list owner and I am sure he can help you out with that.

 

[dlively]

Thanks again Lou, sorry I haven't replied sooner but trying to live in my house with reconstruction going on I frequently have to move my computer system or just move out of the way. Life is not normal in south Slidell. I read the pdf help file and it had the instructions there but I still haven't gotten any decoded info from Pro96Com. It could be a screen size problem for the display as I run 1280 X 1024 screen size which is more than most. Workers will be here this weekend so I don't know when I will get to snoop the airwaves but progress is starting to be made on the house at last.

Well I understand the work going on...As for the screen issue, it doesn't make any sense, have you maximized the window? Doing that should cause it all to fit in the screen (in case for some reason it is larger than your window). Once it is hooked up and you have followed the directions in referece to putting the radio in PC/IF mode all you should have to do is click on the button at the bottom of the screen.

 

[loumaag]

Okay, there is new information and things to watch for in the NOLA metro area.

There are at least two 700 MHz systems operating in the NOLA metro area. There is the LATIE system previously ID'd and at least site (tower numbers) and some control channels ID'd from the beginning of the month when I was in the area and running Pro96Com.

The LATIE system has a SysID of 1bd. This will display (as well as what tower you are listening to) if you hold on the CCh with either a BCD396T or a Pro-96/2096. (BTW just FYI, the BCD996T is now shipping.) The other SysID that has shown up is 14d and has shown up with control channels: 764.28500, 766.28125, and 766.78125.

It is obvious that at least 2 systems are in use in the NOLA metro area, but this actually raises more questions than it answers.

First, the 766.28125 & 766.78125 frequencies are not licensed except by the Louisiana State License covering the entire band for the state (WPTZ793). The 764.28500 frequency doesn't fit the band plan, so it may be reported incorrectly or almost anything.

Second, there is no telling if these two (maybe more) systems are tied together right now. I saw no evidence of that on the Pro96Com runs I did, but then I only had a limited chance to do any research.

What is needed is those of you looking into this in the NOLA metro area is to make careful and copious notes of what you hear, and what CCh is controlling what you hear. When you report a new control channel (or any channel actually) please make sure you know what system is is representing. Also, if you are monitoring the newer one discovered (14d), try and figure out who it belongs to. It may be a parish system or it may be just another part of the LATIE system, in which case we can reclassify the LATIE as an Omni-Link system with multiple SysID's.

This may help shed some light on the situation:

This is for Region 1 of the project straight from the LATIE website.

ok, my understanding of things is that there are 1 or more radios being demoed to varies police and sheffirs dept. i know so far baton rouge and baker pd have both tryed it. the portable had a rssi of 60 from baker to the tiger statium. also lsu pd is using the system right now. and 2 more sites are going to be installed in the next 2 weeks. one on the states 500 foot tower on florida blvd. this will be the hub site for baton rouge. the state is wanting to have all the police on their system. its just up the the local dept. to get their own radios. there is a lot more in the works, so far i have not confermed most of it yet.
will advise on location of the 3rd br site soon.

 

[loumaag]

The PDF's linked are good background. The second one (post hurricane data) is good but only marginally correct. We know that there is a site at Bridge City on the air (both from observations and an actual radio reporting the site), so you have to take that map with a grain of salt. None of that addresses the multiple 700 MHz systems however.

A query to the Pro96Com yahoo group received an answer from the software author. If the site being monitored is linked to another system, it will be reported by that site (in the software). Since the only runs I was able to do was on Bridge City and the site (somewhere) in NOLA, neither of those show to be linked to another system. Of course that was at the beginning of May, anything may have happened since then. What is needed is some of you with Pro-96's or 2096's to jump in with some runs on these other towers/systems so we can get some hard data to analyze.
