DMR TIII Network 13

[gary123]

I went to check the Baden site and its off the air.

Some odd propagation happening today, I just found Grimsby 17.1 on 420.3625. I'm trying to map it now with DSD+FL

That frequency is part of the Canquest Comm system out in the Niagara area..

I think I found another site for this tonight.. Site 17 is reporting a cc on 463.3875 cc 0 which according to the TAFL it belongs to Communitronics out of Ballantrae.

Site 04 is back. Same freqs.

 

[gary123]

had time to look at site 4 with DSD.
2019/02/16 15:57:53 Current network: L13
2019/02/16 15:57:53 Current site: L13-1.5
2019/02/16 15:57:53 TIII system date/time: Saturday February 16 16:03:00
2019/02/16 15:57:57 L13-1.5 neighbor: Site L13-1.6; CC=422.4625

phyberoptics here is the aloha line
Aloha SysCode=10.1100.00000100 AB;

One thing I dont see in the DSD dump is the LCN value. Ill be back in the area tomorrow if somene can tell me how to get it.

 

[Ubbe]

It will tell you the LCN in the activity window whenever a voice call are set up. Use 419.975 as the base and multiply the LCN, odd numbers rounded up to nearest even number, with 0.00625Mhz and add the base to get the frequency. You can look in the event file in the DSD folder for the LCN's if you missed them.

[gary123]

Thanks Ubbe. Ill see what happens there is very little voice traffic on the system thats why I missed seeing it.

 

[DRL-XM43]

We have a strong signal in my vicinity - not much traffic on it although I have heard the odd voice
463.775

I think that site is Williams Communications out of Clarington.

I think you have set the DSDPlus.networks file incorrectly. Set the area lenght to 2 and the site numbering will display correctly.

I think that is correct Matt here is the map view.

 

[gary123]

I had a chance to log site 4 today. there is very little activity on it. I am still trying to resolve the LCN. This is the filtered information I got.

2019/03/06 21:53:26 DCC=0 Private call; Tgt=5047123 Src=5047143 Ch=2652 TX=422.775 RX=427.775

2019/03/06 21:53:40 DCC=0 Private call; Tgt=5047143 Src=5047123 Ch=2822 TX=422.9 RX=427.9

2019/03/06 21:54:02 DCC=0 Private call; Tgt=5047123 Src=5047143 Ch=2651 TX=422.775 RX=427.775

The CC shows up as 2821 and is 422.9 slot 2.

 

[slicerwizard]

I doubt that the CC is on slot 2.

LCNs should be 1325 and 1410?

 

[Ubbe]

Odd channel numbers are slot 1 so 2821 for the CC uses slot 1 as it should for TierIII systems.
But there's 85 LCN steps between 422.775 and 422.900 which have a 0.125MHz difference. That doesn't compute. That's a 1.470588KHz frequency step for each LCN step.

The DSDPlus.frequencies file are probably set up incorrectly.

/Ubbe

 

[gary123]

Ubbe. thats what I was thinking. I have just the default settings in DSDPlus. What changes should be made?

When I punch up 422.900 as the CC the 536 says CC0 slot 2. FYI the CC moved back to 422.7750 today still showing slot 2. The BCD536 is running firmware 1.25 which is the latest.

 

[slicerwizard]

The DSDPlus.frequencies file are probably set up incorrectly.

The .frequencies file has no effect on DFA data pulled straight off the control channel.

 

[Ubbe]

If it's a direct frequency assign system, are the control channel sending both channel numbers and exact frequencies?

If it only sends a frequency, then where does that channel number come from, the DSDPlus.frequency file? It needs straightening out so that it looks more logical. But, Upman indicated in another thread that Uniden might not have the DMR DFA systems fully figured out yet and they want debug files to be able to do that.

/Ubbe

 

[slicerwizard]

I assume you can see post #53...

 

[Ubbe]

I've fine combed Internet and only reference to DFA are Nexedge Generation 2. So I will assume this system works as old Motorola, new Tetra and new DMR TierIII that it uses a base frequency and channel numbers are counted upwards from that frequency and the control channel only sends out channel numbers, no frequencies. And then the DSDPlus.frequency file are very much in use to display the correct frequencies in DSD+ that relates to the channel numbers.

Unidens DMR scanners only go by channel numbers that are programmed next to a frequency and that frequency are used by the scanner, whatever that frequency might be. To be able to program a Uniden scanner one have to correctly link a channel number, LCN, to a frequency and either need to use LCN finder or have the frequencyfile in DSD+ correctly setup to get any kind of helpful info from that program.

The channel numbers and frequencies found so far doesn't match.
