Decoding LTR Standard with Unitrunker

[Paulburton0]

Hi,

I'm a little confused about receiving LTR Standard with Unitrunker. From what I gather, LTR Standard doesn't use a dedicated control channel, instead is uses subaudible tones on every channel to convey control data. That said (assuming I understand that correctly), how do I set up an LTR Standard system? Do I just need to tune one of the channels, and wait for Unitrunker to decode the control data to discover the channels and hopping scheme?

Unitrunker doesn't decode LTR.
What are you using for a receiver?

I have two RTL-SDR dongles that I use for P25 and such.

You might be able to use one of the LTR decoders listed at Trunked Radio Decoders - The RadioReference Wiki

Yes, I see that SDRTrunk is in the list. I've played around with that and I think I got it working OK ... I just wondered of Unitrunker did it as well. Thanks anyway!

LTR Analyzer works great for me. Of course, I don't do trunking of LTR. I simply use LTR Analyzer to determine LCNs. I use SDR# and feed the audio through a VAC (virtual audio cable), and then I use that output as input into LTR Analyzer.

Unitrunker supports LTR decoding only through certain "inline" scanner models.
