DSDPlus Is this DMR trunked or not trunked?

[AngWay]

Ok maybe this is a trunked system . i see signals and they are constant like the p25 control channels are. but none of this is in the RRDB , if someone could help me figure this out it would be a huge help and get the database updated hopefully . because i'm getting DMR that is suppose to be NXDN thats what the RRDB reflects the frequencies as, i have 4 of theses frequencies idk maybe they are a trunked system that is new.

In the video i'm attaching you can see the signals that are DMR i'm showing only 2 of them in this video there are 2 more close by, now if i park on any of them it will be silent until traffic starts on it then i'll hear traffic, i hear the same traffic on all four signals, the two signals i'm showing in the video are 155.7000 and 154.8600, the other two are 152.1250 and 154.5500. These signals just started about a month ago they use to not be there.

I really just need to know how to program them into the radio using sentinel, i know how to program them i just need to know which option to choose because they are several in sentinel such as dmr one freqs motoTRBO and motorola . Thanks.

Thanks for everyone's help

Your not going to get much info as your again not showing all your windows

A few have asked you to enable zoom in FMPX so they can actually see the signal but you still choose not to enable it.

Yours, without zoom,



FMPx with zoom



Your still not showing the channel activity window.





When asking for help, show all windows.

Again, your in an area where a leasing company has many freqs licensed under multiple emissions. You cant go by there are two here and others close by and assume its a system. Have seen systems that have freqs of 450.xxx with 460.xxx and 480.xxx in the mix. Thats 10 to 30 mhz away.

Your best bet is to drive by where there is supposed to be nxdn, and see what's actually being transmitted. If you get nxdn there, and dmr at home, then 2 different agencies are licensed to the same freq and one is using dmr and the other nxdn.

Before making submissions to the database, make certain you know what and who you are listening to.

Ok i apologize , here is a video with everything showing ..The channel activity window does not show anything at all, i know i didn't show it in this video but there is nothing to show . anyways here is the video .

Video

 

[AngWay]

Just for clarity here is a long video of what is happening .. also all of these DMR channels play the same traffic when there is traffic.

Video 2

 

[dave3825]

All we see in the video is you clicking random signals. Don't see any traffic, let alone the same traffic on different freqs. Get rid of the window circled red.




Set these windows like this.




Adjust the PPM on your dongle. Its off. Lower your gain, your noise floor is very high. Let it run a while without clicking on other freqs. The purple (in your video) is gps data. Load LRRP up and see where the radios show on the map. Could give a clue as to who they are.

The auto center tuning appears to be pulling the signal onto an adjacent channel. As was just mentioned adjust the PPM (p/P)
Your step is incorrect for VHF Hi. you want 7.5KHz in the US
Your signal is weak so you have compensated by putting the gain higher which will likely increase the errors. The second line is a good place to be
The window that is blocked will show errors and if the signal is data or voice. I believe I could see the word "data" during the noise through the little opening
You do not use scan to monitor a trunked system, the software sits on a control channel and tunes to the voice channels. A typical control channel is steady 24/7 and usually does not change or not too often.
It appears that you have selected "CC Monitor" but have only 1 SDR running. Use "Combined CC/VC Monitor" under the Control tab in the menu.

Listen i'm not asking about anything with dsdplus the question here was to be focused on the DMR frequencies . they are a constant signal 4 of them and i'm wondering are they trunked systems are those data channels, see they are just like the P25 control channels i do hear traffic on them from time to time the same traffic on all 4 channels. i was clicking around onto each of the channels so you could see how they act.

 

[dave3825]

We know that but DSDPlus and its windows are very informative. The windows can paint a picture, in conjunction with you writing down those 4 freqs, and searching the FCC site, not radio reference, and see if you can locate a license that indicates those 4 freqs on it. Its either going to be conventional or trunked.

Try only what's circled red. Sorry, my paint 3d seems to have taken a dump.

What you showed in the video looks to be DMR conventional. If it were a part of a MotoTRBO trunked system then "CON+ , TIII or CAP+ would be displayed along with net ID, Site ID (& neighbors list if broadcast) on the bottom left of the event window

i do hear traffic on them from time to time the same traffic on all 4 channels.

Could be networked conventional

I searched the frequencies 155.7000 didn't show a place that looked familiar but 153.1250 shows what it could be it's dickenson county and thats the traffic i am hearing on those freqs. here is the screenshots. i don't know what to make of them tho. it doesn't show if it's DMR also

Oh ok thats what i was wondering, i have never seen "CON+ , TIII or CAP+" ever so i don't know what to look for all i have ever seen in dsdplus is DMR BS DCC: i did see tier 3 once .

Why are these signals just constant then with rarely traffic on them, i thought if a freqs was constant like that it would be a control channel because thats how p25 trunked works .

Keep in mind not all traffic carried on certain stations is voice traffic. Your screenshots show LRRP data, so most likely that. This thread has an explanation on what it is. See also posts 6 & 7 on this thread

Cap+ does not display net id

Normally, you have to click the freqs tab, then on the right side, emissions. That will list what its licensed for. Unfortunately the FCC site is taking a dump again. What a ****ty site.

If you look up the license in radio reference, you will see that it is , A, a leasing company, and B, licensed for multiple emissions.



So keep looking at licenses until you find one with all 4 of the said freqs.

CAP+ has no net ID, only site IDs

Yes it does, you need to click on Frequencies tab then Emissions defined view. DMR emissions are clearly there (as are NXDN although not in use)

I don't get what u are seeing. i just see a bunch of numbers. i always just looked for DMR

Yeah when i click on frequencies it goes blank the website must be acting up. so what u see there it says mototrbo thats trunked isn't it? and thats from 153.1250 correct?
