    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.

Has anyone else noticed what appears to be a MOTOTRBO system running in the Albany area on 451.525? I am pretty new to DMR so I may have some of this wrong. When monitoring the frequency in WinDSD and DSDPlus, it seems to identify as being part of a CapacityPlus system. It looks like this is licensed to the SUNY Research Foundation in the area of where SUNY Poly is. WQCA455 (Research Foundation of SUNY) FCC Callsign Details

I have monitored the other frequencies in the license and have seen some data being decoded on those but not as much as 451.525. So, I'm guessing that is the rest/idle channel (sorry don't know the correct term, don't believe it's called control channel on ConnectPlus). I get some audio decode but it is so garbled that I can't tell if it's encrypted or if I' just too far away. I'm hoping someone closer and with more knowledge in DMR scanning can help identify it.

I did search the database and forum posts and haven't seen this discussed before. Attached is my WinDSD log in case anyone else can decipher it better.

I just downloaded win dsd v2. How do you get a log file out of it?? Anyway, back to yours, it reflects dmr, nxdn and mototrbo. Does win dsd indicate if its connect plus, nxdn or cap+ system?

You could download dsdplus and have sdrsharp or any sdr feed dsd and maybe see more info. Not familiar with windsd but have been using dsdplus for a while.

I should have mentioned, I did start monitoring it on dsdplus but tried windsd because it shows more info in the output. I got the log by piping the command output to a file:

"windsd -i pa:1 -o pa:4 >> windsd.log".

Sorry, I misspoke in my post. It indicates CapacityPlus, NOT ConnectPlus. This is from the sting in that data stream "MotFS Cap+" according to the readme that means MOTOTRBO CapacityPlus. There is also a string that shows up, "MotFS LC+ Site Info FL:3 Slot:0 RCh:1 Site:4 AjS: 1(RCh:1 )" that indicates it to be a Linked Capacity Plus system and that this is Site 4 and it is adjacent to Site 1. Again this is my interpretation based on the readme file.

EDIT


Never mind, I see its working now. But is there a list of commands anywhere?

Ok I assume I need to make the above a bat file? I did and it gave me a log file but its way to short for the amount of time its been running. Is the a list of commands anywhere?

Thanks

My cap+ string looks different . I do not have the word site anywhere in the txt file

CACH: Cap+ RCh:1 R?:0
Sync: +DMR mod: GFSK inlvl: 16% [slot0] slot1 CC: 1 CSBK LB:1 PF:0 MotFS Cap+ Ch Stat FL:3 Slot:0 RCh:1 Idle
Sync: +DMR mod: GFSK inlvl: 16% slot0 [slot1] CC: 1 CSBK LB:1 PF:0 MotFS Cap+ Ch Stat FL:3 Slot:1 RCh:1 Idle
Sync: +DMR mod: GFSK inlvl: 16% [slot0] slot1 CC: 1 CSBK LB:1 PF:0 MotFS Cap+ Ch Stat FL:3 Slot:0 RCh:1 Idle
Sync: +DMR mod: GFSK inlvl: 16% slot0 [slot1] CC: 1 CSBK LB:1 PF:0 MotFS Cap+ Ch Stat FL:3 Slot:1 RCh:1 Idle

I will have to do some reading to know what I am seeing.

Been trying to figure out a 4 freq system.
