• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

So, forgive my ignorance, but since this is local to me I figure I should learn more. Ive always just monitored analog standard transmissions - what is involved in monitoring an LTR system? I know you have Control Channels, thats the LCNs above I believe. What else do I need to know, and how do I go about monitoring this setup?

LTR can be monitored in conventional mode, the only downside is your scanner won't display the talkgroup so you won't know who's talking. There is no control channel, because all the trunking data is subaudible (kind of like a CTCSS tone). Most systems have most of the talkgroups default to a home channel (aka home repeater). For instance the RTA bus talkgroup on this system has home channel #03, so you should be most likely to hear RTA buses on 464.60 (LCN 03). Then if another radio on a different talkgroup keys up (whose home repeater is also LCN 03) the system will say "LCN 03 is busy, Goto LCN x instead" and they will show up on another frequency.

To program LTR on a Uniden, basically just set the trunking system type correctly and program the frequencies in LCN order (so the LCN 03 frequency goes in the Ch 03 frequency slot). Do a forum search, see the LTR forum, the Uniden forum and the LTR system wiki page for more info.

No one spoke up so I've deleted the old system. Here are the old "Communications Enterprises" talkgroups, for reference:

Code:
0-01-002 	A 	SLO Tran Bus 	SLO Transit Bus Operations  	Transportation 
0-01-003 	A 	SLO TranData 	SLO Transit Data  	Data 
0-01-015 	A 	Paratra01015 	Paratransit  	Transportation 
0-01-017 	A 	RTA Bus No 	RTA Bus Operations (North County, formerly CCTA)  	Transportation 
0-05-015 	A 	RTA SoCoSupv 	RTA South County Supervisor  	Transportation
