LTR Talkgroups Question

[zzdiesel]

I have a RS Pro-2055. We have three main trunked systems that I'm trying to program right. I have each individual trunk in it's own bank. The problem is when I program the TG in one bank; it seems to also change the other two. How can I keep them separated?

 

[zzdiesel]

It doesn't change the talkgroup code itself. It changes the TGID number to all three to the same on all three banks. I hope I am making sense.

Sorry, making sense you are not, as Yoda would say! Tell us which systems you are trying to program in. Perhaps all three systems have talkgroup IDs that are similar, i.e.: area code 1, home channel 1 and talkgroup 001 is common. And the company(s) who set up the systems did it that way to confuse listeners who might want to listen in. Another idea is that the three systems you are programming in are actually only one system and the LCNs are not correct.

Here are the three talkgroups. I just discovered that this happens in the three channel banks even using different TGID banks.

1. 0-03-095 R03
2. 0-06-130 R06
3. 0-07-005 R07

Numbers 1 & 2 are owned by the same company, but they are about 30 miles apart.

OK, we are getting there. I suspect you are talking about Warner Communications? I notice that most of the LCNs listed for those systems are not confirmed and are listed as 1,2,3,4,5,etc. Seldom do LTR systems follow an order like that, rather they use an offset rule, or skip LCNs. For instance LCN#1, 3, 5, 7, 9 and the even numbers will be skipped. The first thing you should do is confirm the proper LCN position for each frequency. You can do that by simply entering in the frequency and watch what pops up. The 2055 displays the talkgroup and over on the right side of the screen the actual home channel will appear, i.e.: R03. Occasionally, a talkgroup will appear on an overflow channel if that particular talkgroup's home channel is tied up. You may see 0-03-095 appear on LCN#1 in the system. The R01 will tell you that that frequency is in fact LCN#1 and not #3. Once you figure out the proper LCN positions for each frequency you can enter them in the correct channel number as LTR system and monitor the system. Beware however, companies who set up LTR systems like to mix and match frequencies and figuring out which frequencies go with which systems can sometimes be very frustrating process. Good luck.

Thanks. Now that makes sense. Looks like I'll be busy for awhile. These small communities don't always talk very often.

There is still one thing I don't get though. Why would the TGID # all stay together on each bank when you change it for one bank? I'm not talking about the code changing. Like the one I listed 0-03-095 is R3. I put it in the #3 slot, and then the second is 0-06-130 R6. So I put in the #6 slot and the Warner is 0-07-05 R7 and then I enter it the #7 slot. Which ever one I set it on; say like #3; the other two banks will also switch to TGID #3

Diesel,

I'm really not following what you are asking in that last paragraph at all. Work on decoding one system at a time. Verify the channels in use with the FCC database, sometimes more frequencies are listed on the FCC database than are listed on RR database. Then when you think you have the system figured out, put the frequencies in their proper LCN position, in one bank only, and listen to that one bank for a while to confirm your research.

Again, please tell us which systems you are trying to listen to on the RR database and perhaps we can help you seperate the wheat from the chaff!

Answer to your LTR problems: RS PRO-92 or RS PRO-2067

Are you saying those are the scanners I need or are you asking what scanner I have?
