Need help LTR BC785 cant get it working

[nwadler]

I am trying to track a conventional ltr system. I can not get it to work. here are the frequencies. I know these are right and I see a few ID come up when stopped on the channel but it wont stop on the channel when scanning and am not able to use a search feature like edacs. Is there somthing I am doing wrong. This is a ny syracuse system.
452.0125
452.3375
461.8625
463.2125

I could not find anything in the RRDB for these frequencies. Which system is it?

 

[FPO703]

It may be an LTR Multinet system. In which case, you won't be able to 'follow' the system with your current trunktracker.

FCC shows WPMY630 - LEO MAC RADIO SERVICE INC located on Pompey Hill, south east of Syracuse
http://www.leomac.com/

Add 451.7875 to your list per the FCC database.

common errors with LTR systems and scanners:
- right format - there are several LTR formats and the scanners will only work with plain LTR. (the most popular at this time and what Leo-Mac uses)

- proper order of frequencies - Uniden scanners need the frequencies is a particular order called Logical Channel Number. (not necessarily numerical order) This is set by the system operator.

- settings properly set for trunking and system type - there should be a small "L" next to each channel number. The bank needs to be set for LTR trunking.

There are more in depth writeups on how to determine LTR LCN in the archives. Try a search.

Some quick things:
- Not all freqs in FCC database may be in service yet.
- Usually (but not always) the freqs that are active have what sounds like an open carrier for a split second every so often. If you sit on each freq for a couple of minutes you should hear this. That should narrow down things some.

Send me a PM if you are having trouble. I'm no expert, but have successfully figured out most for a local LTR system that wasn't documented much.

I was told by the guy that the first frequency is not part of the system and I can tell that by listening because unlike the other open channels there is no open type of sound like someone hit the ptt every 11 seconds(Yes I did time it) and it still wont work

It won't work until you get the channel order correct in the scanner. This means that the freq that is used as channel1 needs to be in channel 1 (relative to the bank you are in), channel 5 needs to be in 5, etc. The channels used most often are 1, 5, 9, 13, 17. Yes there are gaps, and no they are almost never in ascending or descending order by frequency.

Try programming one of the most active ones into each of the first 20 channels of the bank you are in. When it stops and you see an id in the format of 1-5-202, stop the trunking and see what channel number it is on. Note that and then program in another active one into ALL 20 EXCEPT THE ONE JUST IDENTIFIED. It's a pain, but without computer software, that's the only way that works for me.

There is another way. Try programming each channel independently (it can be in any cahnnel position in the bank). Set LTR mode and watch in Manual mode to see what the majority of users have as a Home Repeater, digits 2-3 of the 6-digit ID. Repeat for each channel. That should give you all the HR numbers. Then program into the scanner in the correct channel positions. Best to do this during a relatively quite time, to avoid confusion from "trunking out".

This is weird I dont here much traffic but most of the traffic I am getting is not bringing up id numbers. I have been assured this is regular ltr and not passport or multi system so it sounds like there are regular companys with these channels not trunking it. Confused so am I. I am trying to get somthing from the company maybe they will give me the lcn number order. Who knows. Thanks all for your help already.

Just to double check...are you sure that the channel you have programmed is set up for LTR, and trunking is enabled (you should see L TRUNK in the display).

Just to let you know I talked to a person who runs this system he gave me the lcn order and it still wont work so I have stopped trying to monitor ltr. Thanks for all the help

Sorry to hear that. Sure can get frustrating sometimes.

Can you give us the proper LCN of the frequencies so that other can give it a go?

here yall go. The tower is located in pompey NY and runs about 100watts I believe.
7 - 452.0125
11- 452.3375
15- 461.8625
19- 463.2125
Correct LCN order there is no other frequencies and it is straight LTR. If you figure it out give me a shout. I am going to look at it and try again.
