MotoTRBO/DMR Decoding: PC Signal Decoder using DSD, Experience & Insights

Hello yesterday on the internet I came across a decoder program
MotoTRBO / DMR decoding on PC with DSD

the program is to decode the signal mototrbo has anyone met this signal decoder?

Yes, he did.

What about something more specific? Any instruction or something?

The Internet is bursting at the seams with guides, programs and plugins, and you are brazenly asking for instructions?

Moderated By c2h5oh:

Regulations point 3.1.9. It is forbidden to disseminate ironic, mocking or malicious content that shows disrespect for other Users or third parties.

Not so brazenly but politely I asked, and you don't have to jump at me right away ...

There is only one topic in the visible forum, but since writing, prompting is so difficult for you ...

it's a shame to score points ....

greetings

To start playing with the scanner you need to lead the discriminator socket: http://www.discriminator.nl/index-en.html

Then you need to set the signal input level correctly. For simplex (direct) it should be 6-7%, which will translate into 11-12% for drives.

To set it up, please refer to this guide: http://ukradioscanning.com/viewtopic.php?t=312

You can check the correct settings in the "old" DSD versions (because they show "level"), which you can download from here:

http://wiki.radioreference.com/index.php/Digital_Speech_Decoder_%28software_package%29

a) you create a DSD folder on your computer:

b) extract the downloaded "dsd-1.6.0" [download ZIP] into it

c) extract the downloaded "mbelib-1.2.5" [download ZIP] into it {some of the files will be the same, so replace it}

d) you transfer the downloaded "Windows Binary with P25 / DMR Filtr 1.6.0 Beta" to it

e) extract the downloaded "cygwin1.dll" to it - https://app.box.com/s/kcoeo663lyettrzg7msu

All files are to be directly in the DSD folder. After unpacking, they must be moved.

After running "dsd160", you should apply to setting the signal input as described above.

Instead of the radio, you can use a DVB-T tuner, for example from "Not Only Tv LV5TDLX" for about 40 PLN, install the "Virtual Audio Cable" program and configure the outputs accordingly. You have a scanner that works from 24 to 1100MHz in this version with this tuner working on the FC0013 chip.
Below are links to the tuner descriptions, the page with the description of the new dsd + 1.5 program and the page with the VAC program settings.

In the attachment I added a file with the description of the DSD1.4 program and card settings as my colleague wrote early.
Does anyone have a program for displaying sent text messages?

Welcome gentlemen. Annual excavation, but the theme is still valid. Unfortunately, I do everything according to the instructions and all I hear is gibberish at all input volume levels. Can anyone help? Or is it coded and I will do nothing.

Download this version and insert the logo window: http://www35.zippyshare.com/v/37884159/file.html

You will copy it from the DSDPlus.event file. Open it with a notebook or its derivatives.

I dalej tylko jakiś bełkot

What device do you have? If something outside of SDR, how did you perform the discriminator? What frequency do you listen to this on?

And there is a newer version like something: http://www.dsdplus.com/download-2/

Uniden ubc355clt
I made the discriminator according to http://www.discriminator.nl/ubc355clt/index.html
two 2.2 k and one 5.6 kW resistors in series - maybe something wrong with them? mass from the housing, mass to mass in the jack and resistors to the channels
Frequencies within 168, ....

Thanks for your concern

Something like that happened in the logs

2016/02/07 14:23:16 LRRP; Tgt = 12421; Src = 11901

Download this application and record me a sample with the characteristics of 48kHz, 16bit, mono:

1 what goes with the scanner
2 is what I hear in DSD

The discriminator is correctly output.

LRRP is the display of the position on the map: http://forums.radioreference.com/voice-control-channel-decoding-software/299445-lrrp-exe.html

In this case, the radio wants to send the position to the console, but there is no place to download it, because either the GPS has not been turned on or it is turned on, but the radio does not see the satellite due to the lack of an antenna.

There is no voice mail in both recorded files, so you don't hear anything.

Can you recognize in the window that there is a voice transmission?

Yes. The call to everyone looks like this:

Enc Bcast Group call; TG = 16777215 RID = XXXXXXXXX Slot = 1 Alg = EP KeyID = XX 1s, where

TG: group number

RID: Radio ID

Slot: first or second time slot

AlgEP - Enhaced Privacy, i.e. extended masking

KeyID - Key ID from 1 to 255, where the value is a maximum of 10 characters using the symbols 0-9 and AF.

1s - talk time

Group conversation:

Enc Group call; TG = XXXXX RID = YYYYY Slot = 1 Alg = EP KeyID = XXX 10s

Private conversation, i.e. radio A with radio B without the possibility of receiving by other radios, the so-called Private Call is not on hand, but I am looking for.

Thank you very much. Just one more question, is what I recorded is Mototrbo?

Yes. You must listen to this longer. Even when leaving the house, leave the scanner on.

After returning, run the DSDPlus.wav file, where it will dump decoded conversations for you.

If the signal is clear, the program will mute the encrypted gibberish. Also, do not be surprised if there is something in the log and not in the recordings.

The gibberish will either be on data you have provided or on a weak signal that the program will not recognize and judge to be unencrypted.

Ja Panowie wczoraj wszystko ładnie zainstalowałem, wszystkie sterowniki i dodatkowo DSD+ i Audio Cable. Powiedzcie mi jedno DSD+ czyta mi linijki normalnie ale nie ma voice... Jestem zielony akurat w cyfrówce. Od wczoraj mam zakupiony sdr rtl2832u. Rozumiem, że DSD+ sam rozdekoduje rozmowę ale w konsoli musi być "voice" ? Skanuje na paśmie 172-174 Mhz.

Sync: no sync

It is not a voice but a date. Besides, the signal was hopeless. Just mistakes.

I think you are choosing your devices wrong. In my opinion, the input and output cannot be the same, but I am thin with SDR, including VAC

Even if the voice is heard, you will not hear anything because, as your colleague pointed out, you cannot have audio input and VAC output, you should have an output, as shown in the photo for the speakers. DSD + automatically sets the inputs and outputs marked as one as default. In order for you to detect the speakers as one, you must set the computer's speakers as the default device in the computer card settings in the playback options. Then everything will run smoothly.


Recently I got a lot of news on PW, so I decided to create a topic that serves as an installation guide for SDR tuner, SDRScharp and Virtual Audio Cable. I hope it will be useful for beginners in the subject of SDR.
Greetings.

Gentlemen, a short question, I have a stationary scanner and sdr connected through the BNC tee, as I add to the sdr antenna, the reception on a stationary one is deteriorating. My question, are there any filters, etc., maybe a special splitter? Greetings.

Moderated By kriss51:

I can see that the topic has developed a lot, and the author of the topic has not written for over a year. You just stuck to someone else's topic. May it happen to you one last time. 3.1.19. Out of respect for the questioner, create your own topic. You can only add a solution to the problem.

How to run this dsd +

Moderated By kriss51.:

You have not even written what receiver you have, in addition, everything is described in the topic. Second: regulations- 3.1.19. Do not send messages on archival topics if this is another question, in particular other than the questioning person. Out of respect for the questioner, create your own topic. You can only add a solution to the problem.
CLOSING.
