LTR ATB meaning?

[Airdorn]

Hi there all.

I'm using LTR Analyzer and I found a system that, during the CWID, displays ATB. Like so:

- OSW: 1 15 15 255 00 04 BUSY/CWID ATB LCN=15


I know that means 'all trunks busy'. This happens all the time during this system's CWID and any time I hear a conversation during the day. Even at all hours of the morning that's what's displayed.

Does that mean that particular LTR Standard system is very small and just using one channel?

Also, the frequency of which I'm receiving this data is not in the RR database or the FCC database.

ATB means all channels are busy. If you see it all the time no matter what then it probably means the system only has one channel.

Also, the frequency of which I'm receiving this data is not in the RR database or the FCC database.

Nobody will be able to help with that unless you post the frequency and location where it was heard.

Yep, one channel LTR system/site.
