Official LATIE Thread

Lou, if I understand you correctly I can load all of the CCH freqs and the 396T will properly track....in other words, if I am in Lafayette and I often receive the Lafayette Tower and the Abbeville Tower then there is no need to program them as two separate systems. If there is traffic on the Lafayette Tower then it will properly track the conversation with no interference from the Abbeville Tower..........is this correct because it would dramatically reduce the amount of data I had to enter into my scanner....

No...well I think no. I say think, because you changed half way through. Let me try to say this this way:

• A BCD396T (while working on a TRS) will only track one CCh per system, and it will be the first CCh that it finds as it first looks at the system.
• You can put all the CCh (and alts) for a wide spread TRS (like LATIE, Entergy, or the LA State 800 system) in one system setup, but it will only track on CCh at a time in that system; however, if you are traveling through the area as that first CCh gets so weak as to fall out, the radio will find the next CCh it can hear. This allows a somewhat seamless ability to travel through a wide area without worrying about pushing buttons.
• If you want to monitor a specific agency (that you are in range of) you should find what site is always active with the appropriate TG's; that is the one that always carries the traffic, like perhaps the closest one to the dispatch point. That is the site/tower you should set up for that agency as a single system. And yes of course it will not be interfered with by another tower (not counting bleed-over or desense).

With all that said, in your case, the Lafayette and Abbeville sites are pretty close (not to mention the not yet active Parks one) so if you want to hear all of them, at the same time, you are going to have to set them up as separate towers.

Today I came across a control channel not yet in the database. The frequency is 764.20625. I began hearing it on LA HWY 10 about halfway between Clinton and Jackson. As I got closer to Jackson it got stronger. It remained strong all the way to St. Francisville and from there going South on US 61 I could hear it until I was halfway to Baton Rouge. The only talkgroups I heard on it were a couple of the new Acadian Ambulance talkgroups. It comes up as site 132. I don't know the exact location.

This same frequency is used as a control channel by both the Jennings and Berwick sites. As the crow flies Jennings is 87 miles from St. Francisville and Berwick is 77 miles so this is definitely not one of them.

I won't speculate as to the exact location, but there are at least 5 proposed / under construction sites in that "area." Without knowing exactly where, it would be hard to guess.

I took a drive up there to search in November, when construction was "supposed" to have been underway, but there was nothing all the way to Angola.

Obviously, things are progressing!

Baton Rouge or EBR on LATIE

I'm hearing what sounds like Baton Rouge or EBR sheriff on LATIE now. Talkgroups 17050 and 17051. I'm not familiar with the "normal" radio traffic for these agencies so I can't confirm anything, but I know its the Baton Rouge area. I heard some traffic reference the Scotlandville substation, and some other traffic about Stumberg and Jefferson Hwy. If anyone monitors LATIE in the BR area you may want to start monitoring these TG's to try to confirm them.

BCD996T Config for LATIE System

Can anyone provide the specific trunk system configuration settings for the LATIE System on a BCD996T, or BCD396T?

Specifically the System Type (Assume MOT2)
The Site Type (Assume M-P25)
Any APCO Base and Spacing frequency settings (??)

I have all the correct freqs and TGIDs for the site I'm trying to monitor but so far no activity.

Is the Grey Site (#116) up and running?

Thanks in advance for any help.

Don't know about the 996T, but here is a 396T UASD file for the single tower of LaPlace. You can use that as an example and to the best of my knowledge, 116 is up.

 

[kdragos]

Thanks much.

The USD file should help.

Lafayette Consolidated Government TRS

Any word on when the Lafayette TRS will go to LATIE? I recently noticed a number of new talkgroups posted for Lafayette.

unfortunately the Lafayette system on the Latie will be encrypted. Which means there is not a scanner on the market to receive encryoted signals. And in my personal opinion which BTW ain't even good for a cup of coffee, sucks

Exactly how does that work? Is Lafayette actually part of Latie?

How does the State Police or others that are not encrypted roam onto that site?
If a Lafayette Unit travels to Shreveport can he still communicate with Lafayette?

This confuses me....

To keep from re-writing what others have done numerous times, I would

1) Take a look at the wiki here at RR.

2) Google "how does Motorola SmartZone Work"

That will get you even more in depth. Will provide hours of reading for you

[pitcockm]

Hey Kevin.....thanks for the response.

I'm sorry my question may have been confusing.
It's not the "Motorola SmartZone" that I don't understand. It's the single encrypted site and how it interacts with the rest of the SmartZone.

Anyway....thanks for your advise.

 

[kevins669]

In that case... the site is not encrypted at all. Since the system has the capability, it is up to the individual agencies to encypt the talkgroups that they wish to encrypt.

Obviously, the radio must be capable and programmed accordingly.

You will be able to hear everything else that is not encrypted on that tower.

Hope that helps a bit more.

Jefferson Parish Fire

During this morning’s Fire Station radio checks Jefferson Fire Alarm announced that effective 1200hrs today all Fire Ground communications would be moved back to the conventional system. Anybody have any info on why the move was made?

OK back to Lafayette, I'm getting a psr-500 if it's a year or more till they encrypt. Does any one have the inside scoop on this? Also will the close call feature detect an encrypted digital radio operating nearby.

When they move to LATIE (which they have not yet) then the encryption question will be answered. When they move is more the question.

As for the close call feature, I would guess it would depend on how the scanner is designed. I "think" a BCD396T will stop on the frequency and tell you it is ENCrypted. I only say that because everywhere else in the radio when an encrypted signal is detected, it stops, mutes the signal, and puts "ENC" in the display window. I have never actually used close call to detect an encrypted signal. Besides, you need to be almost on top of the signal to detect it anyway.

Lafayette

To answer a few questions, Lafayette is still a long way from switching to LATIE as a primary radio system. No work has been done in the communications centers as of yet to support the switch.

Some agencies, including mine, are currently using our talkgroups as a secondary means of communications or as a talkaround channel as needed.

To answer the close call question, I just keyed up my portable next to my BC996 on our encrypted talkgroup and the scanner does alert and stop on the transmission. It gives the frequency number assigned, but all you can hear is a static type hiss while the transmitter is keyed.

I believe that is because you didn't say anything, the encryption cannot be detected unless it is actually there, and silence is not "encryptable" (not sure that is a word), try it again while saying something and I am pretty sure it will do the same but when the encryption is detected from the stream, it will mute and display ENC.

Oookay, this is weird. I ran pro-96 com with my PSR-500 today just for the heck of it to look at the info it produced. I was monitoring the Lafayette tower and when I clicked on the tab that shows the info for adjacent sites it showed me a number of sites within a 50 mile radius of Lafayette that were all in the database but one. This site shows up as site 141 with a control channel freq of 769.55625. All the other sites showed the control channels that match those in the database here. I tried to enter this frequency in the scanner but it is outside the range of frequencies that the scanner will allow in the 700 band. Since 700 is supposed to be rebanded is this maybe one of the new frequencies for voice that was formerly for data only? Any other ideas?

On another note I am going to the Greenwell Springs area today in the Northeast part of EBR Parish. I will run Pro-96 Com on my laptop while there and see what sites come up there. Maybe there will be new ones. Since Troop A is still on 800 this is a good indication that there are more sites coming in their troop area.

This is as of December, 2007. Sorry for the old info but, I just got it last week.
