LTR and BCDT

[dgoodson]

I have a new Uniden BCD 396T, which supposedly will monitor LTR systems... and I have zero experience with LTR systems...

I programmed the system for ALabama/Houston County/ Dothan Public safety,
according to the info here:
http://www.radioreference.com/modules.php?name=TRSDB&sid=976

I sat on this system for about 45 minutes, in ID Search, and did not hear a single peep. So either I did something wrong, OR in some way this LTR system cannot be monitored by the 396T.

But I am not smart enough to know if I am wasting my time on this system.. can someone clarify what's what for me?

thanks

The key is having the channels programmed in the proper "LCN" order, and as an LTR system. That is, each frequency needs to be programmed in the assigned slot, for example:

LCN #1 155.100
LCN #2 155.150
LCN #3 155.175
LCN #4 155.200

You might not be hearing anything because the users might not be using that system, the scanner isn't programmed correctly, or the LCN shown on the Radio Reference pages isn't in the correct order.

Try just entering the frequencies as normal channels and scanning them. See if you hear any radio traffic -- if you do, then you know your scanner isn't programmed right or the LCN order is wrong.

If you don't hear any radio traffic, then you know the system isn't really being used much. I'm an LTR newbie myself and it took me a while to figure it out, with the great help of others on the forum.

Good luck!

According to this thread it's LTR Multinet and not monitorable with any scanner.

What is about "multinet" that means you cannot monitor it? The voice was listed as Analog, so I figured I was good to go.

Still learnin'

Don't know ! I'm still learning myself.

In that thread, Julian1 provides an interesting description of what it's like to try to scan the system in conventional mode. Maybe someone else can give you some specifics of why that's different than LTR systems that can be tracked.

Standard LTR (and LTR-Net) and Multi-Net use subaudible data mixed with the voice channel; MultiNet also uses a subaudible dedicated control channel. But that's where the similarity ends. The structure of the data used to assign channels and all other commands is completly different so looking for standard LTR trunking data to trunk with won't work.
