DSDPlus How to make DSD+ work in 2023(RTL-SDR)

[bejk]

The tutorials on youtube are old, since there isnt a new one I am not able to make it work I deleted all the files in a hope some one can tell me how to set it up properly , there isnt a working plugin for sdr # , there is the DSD+UI but I cant get it to work. I just installed the lastest version of sdr# and thats all. I am new to all of this. And one more thing if possible to just make it work with free version not the fast lane one. Thank you

FastLane or public version, the basics are mostly the same (only the features are different) and tutorials are still mostly relevant. Just let us know what type of SDR you have and what system do you like to monitor because thats the main you have to know to start configuration process

Tell us what your looking to do and we can offer assistance.

DSD+ does not need or require SDR#. It comes with it's own RTL tuner, FMP24, which connects to DSD+ via TCP instead of dealing with virtual audio cables.

The plugin that was on rtl-sdr.ru is not working(web site) and If I try with virtual cable as output on audio panel on sdr# I aint getting no sound output to the cable, can someone write a me tutorial how to set DSD+ up correctly to work with sdr sharp so I can see the spectrum. I also tried the new GUIpluginDSD+ but when I select the .bat file cc.bat example I get faild to connect tcp ip:20001 port.
I just want to try how It works decoding digital audio if possible to set it up to work with different freq since I dont know at exactly what freq do ham operators work in my country, and other services

I manage to get it to work the signal graph is working but I dsd+ isnt decoding anything,

..... can someone write a me tutorial how to set DSD+ up correctly to work with sdr sharp so I can see the spectrum.....

As @redbeard already told you, even public version of DSD has its own RTL tuner. It is called FMP. Why to use it over SDR#? Again, take a look at what @redbeard said. And don't worry, it also has a spectrum

..... I also tried the new GUIpluginDSD+ but when I select the .bat file cc.bat example I get faild to connect tcp ip:20001 port. .......

I am not familiar with this plugin but it seems that default command that passes to DSD is to use TCP.

I assume you are located in Europe, so ham band limits there are 144-146 for VHF band and 430-440 for UFH band. For the sake of simplicity we will not discuss other bands. If you want to tune to them it is a whole new level and DSD won't help you or those bands

OK, enough talking let's get to bussiness. I created the most basic startup file so it will use FMP, TCP connection, it will decode all types of digital modes. There is only few things you have to edit to be more precise. Change the extension from .txt to .bat and place it inside your DSDPlus folder. Open it with any text editor and only edit the numbers of the following switches according to the instructions:
-i1 -> this is the number of the RTL-SDR dongle. If you only have 1, leave it unchanged. Otherwise, set it to the one you want to use.
-f144.550 ->this is the startup frequency, you can change it to a desired one or you can leave it and change it once FMP is started
-o20001 -> that's the TCP port which will be used for connection between DSDPlus and FMP. Don't change it
-b9 -> that's the bandwidth. It could be different according to the type of transmission. For now leave it like that. 9 is a good starting point. If needed, change it by pressing b on your keyboard once FMP is started.
-g28.0 -> that is the gain. It defines how much of a signal "amplification" is used. Too low and signals go away, too strong and you will overload your receiver. 28 is good starting point, closer to the high end. Once FMP is started you can change it by pressing g or G on your keyboard to get it lower or higher.
-P45 -> that's the PPM correction. It defines by how much the receiver should be offset in order to be precise when tuning. That's receiver dependent but most of the rtl-sdr dongles are within 30 to 55. Start it this way and let your receiver get warm (10 min of work is enough) then use p or P on your keyboard to set lower or higher PPM offset. Once you found your sweet spot edit this and don't change it.

That's all for now! Hope I don't miss or mess anything Good luck and happy decoding

This is real good info. Thanks for taking the time.

Are you hunting for freqs or do you know the freqs? Are the freqs digital or analog? Makes a difference on how to set up DSDplus.

?

 

[bejk]

I am hunting for freq I just know that between 90 and 130 are FM Broadcast stations emitting. And thank you for your help, all of you .

When running the script you gave me I get this in my cmd
Initiating TCP connection to 127.0.0.1:20001...
TCP connect error = 10061
[No connection could be made because the target machine actively refused it]

You probably already know this but 127.0.0.1 is the loopback IP address of the computer that you are running. Try disabling the firewall on that computer to see if it works.

 

[bejk]

Still same issue

I disabled my av and firewall and still there is the same issue

 

[bejk]

I got it thank you guys for all of your help I just need to remove -b9 argument from fpm command and allow it trough the firewall and It worked

 

[dave3825]

The firewall deal would affect connection but the -b9 would not create any connection issues.

invalid command line parameter: '-b9'

Correct. Supported bandwidth in fmp is (4, 7, 9.5, 12.5) . Either way -9 would not create any connection issues. Either leave it out or change to the appropriate setting. You can always change from FMP if needed.

4 kHz modes:
D-STAR
DSTAR
IDAS
NX48
NEXEDGE48

7 kHz modes:

DMR
TRBO
Cap+
Con+
TIII

9.5 kHz modes:

NXDN
NEXEDGE
NEXEDGE96
NX96
P25

12.5 kHz modes

PV
ProVoice
any other text string (analog, LTR, ...)
