The software allows the recording of the IQ data to a .wav file. Is there a way that this data can be 'played back' into the software for post analysis - ie to run the existing functionality as is but sourcing the IQdata from the .wav file?

SDR++ v0.2.5_beta (Dec 24 2020). If I execute this software, disable view of the waterfall, and exit - thereafter the software 'crashes' when I try execute it again. The only way to get it to execute again is to manually edit the config.json to set showWaterfall to true. Hence it appears that the software has a problem if it is started with showWaterfall set false.

Audio samples provided in comments

I am trying to get the software which I have built, to operate. The software I am using is sdrplusplus-0.2.5_beta_preview2.
I have the following problem

When trying to create an instance of SoapySDR Source (soapy_source) called from
core::moduleManager.createInstance(name, module);

IN the function refresh, line "devList = SoapySDR::Device::enumerate();"
throws an exception as follows:
Exception thrown at 0x00007FFAD0644B42 (SoapySDR.dll) in sdrpp.exe: 0xC0000005: Access violation reading location 0x0000000000000019.
I cannot find the reason for this. The software is finding the dll - setup in config.json is
"modules": [
"./airspyhf_source/Debug/airspyhf_source.dll",
"./plutosdr_source/Debug/plutosdr_source.dll",
"./rtl_tcp_source/Debug/rtl_tcp_source.dll",
"./radio/Debug/radio.dll",
"./recorder/Debug/recorder.dll",
"./soapy_source/Debug/soapy_source.dll"
],

Any ideas would be appreciated

is my firts compile sdrplusplus i am under linux sorry my english i am french ...

is my log need your help

I'm trying to build SDR++ on a mac using the "Building on Linux / BSD" section.

I think I installed all the required dependencies correctly, except for libairspyhf, libiio, libad9361 and librtaudio-dev. I did install SoapySDR, which I think should be enough, but I do still get this error:

-- Checking for module 'libairspyhf'
--   No package 'libairspyhf' found
CMake Error at /usr/local/Cellar/cmake/3.19.5/share/cmake/Modules/FindPkgConfig.cmake:553 (message):

  airspyhf_source/CMakeLists.txt:26 (pkg_check_modules)


-- Configuring incomplete, errors occurred!

Do I absolutely need to install libairspyhf and others, even if I don't want to support Airspy HF+?

Hi, SDR++ not find RTL-SDR nor AIRSPY window error not find module only the Pluto
Installed pothos cubicSDR is running
--- SOLVED ---

it would be nice it you could set a threshold above the noise floor to squelch-break(record audio ) to help unattended recording.

if/when you add audio recording could you add the ability for it to auto make a new time & datestamped file every hour? same as rtl_airband does.
also an option for making a new file every time the squelch breaks, not something i use personally but something ppl tend to ask for.

thanks.

Hi everyone,

I just pulled a fresh copy of the new master branch and tried to compile and run it on debian.
The code was compiled, but after starting it crashes with the following message.

Any ideas what might go wrong?

I changed the paths of the libraries as I did in the old new-dsp branch, but no success.

Hello,
I don't have your mail. I use this page.
I'm working on some issues (from the last release because this version work on windows) like :

• wav audio files sound level,
• adding audio balance slider,

I do a first test with IQ file player.
I think memorize menu and windows state for the next startup.
It's possible to contribuate a little bit on your nice project.

have a good day

It will be good if these hw settings will be in SDR++:

• RTL-SDR automatic gain(available via SoapySDR)
• HackRF or other sdr's hw bandwidth(available via SoapySDR)

Also some software features:

• Variable FFT size
• Decimation(like in gqrx)
• Audio FFT and waterfall
• Stepped gain regulation
• Changing filter width by dragging it's edges on waterfall
• Zoom slider default position is max zoom, when zoom is minimal, i think better to set it to min on start
• Maybe add more accurate filter managing like in SDR#, where you can drag both sides of the filter
• Signal information like SNR when moving cursor on it

Maybe some time shifting plugin like Timeshift in SDR# included into main program.

Currently found glitches by me:

• Long starting time (> 5s)(maybe because of audio devices detection)
• When closing by default close button(cross), it prints exception in terminal like there is some errors
• Some underruns occurs

• Load last source configuration
• Add a loading screen
• Finish the recorder module
• Fix squelch
• CW and RAW modes;
• Bring VFOs to a visible place when changing sample rate if it's smaller
• Add save config for all modules
• FIx slow resamplers
• FIX ALSA ISSUES ON LINUX!!!!

Have an airspy R2 which works ok but not with an sdrplay rsp2.
using Arch Linux.

When trying to run the Windows release, it initially fails because volk.dll is missing,

Looking in your Building for Windows, I noticed
"PothosSDR (for libvolk and SoapySDR)"

Hence these files are not just required for building, they are required to run the application and IMHO should be included as part of the release, even if you didn't write them (as they are open source and you can credit the original source)

BTW. Even after installing those files, the application does not detect my RTL SDR, which works fine under SDR#

Downloaded the latest release

https://github.com/AlexandreRouma/SDRPlusPlus/releases/tag/0.2.3_aplha

I have a generic RTL2832U SDR

USB\VID_0BDA&PID_2832&REV_0100
USB\VID_0BDA&PID_2832

With WibUSB v6.1.76000.1638S installed

Which works fine with SDR# , however it is not detected by this application

Is a different driver required ?

This is not really an issue, other than the missing bit from CMakeLists.txt
But maybe some of it can be recycled by you when adding instructions for Linux:

sdr@sdr:~/sdr$ sdrpp sdrpp: error while loading shared libraries: libvolk.so.1.4: cannot open shared object file: No such file or directory
OS : Ubuntu 20.04.2 LTS

Hello, I used the dpkg method with the .deb of the version "SDR ++ v0.2.5_beta PREVIEW # 3".
sdrpp cannot find libvolk although it was installed from the canonical repository, then from source "libvolk.so.1.4" directly. Nothing helps, it still doesn't work.

Is this a known issue? Thanks

Hi,

this is not very important, but it would be nice to be able to set a decimation to get a bit more dynamic range in exchange for sample rate. Some SDRs with really high sample rates (like the HackRF (and even the RTL-SDRs)) can really benefit from that.

On my build, the recording path is set to %ROOT%/recordings by default. I am able to enter a different path and SDR++ records into that path just fine, but after closing and re-opening SDR++, the default path is back. It would be great if the user's path entered is saved across restarts of the program.

Hello, I try to compile this program on macos. compiling is ok, but when linking error occus. Here I upload the error log, how can I fix this error? thx

platform: macos 10.15.7

log.txt

With SDRplay RSP Duo, I get audio drop outs whatever sample rate and modulation I chose.

On the terminal, I can see line below many times:

ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred

No similar issue with RTL-SDR on the same computer

Something I see is after using RTL-SDR, less audio drop outs with RSP but still some.

Hi, I have build this program success. but when I try to run it, it just crash and throw some error message:

Hi there, I am back. this time I use gcc 10 on macos to compile the source, but failed again. here is the log. Any thing can I try? thx
log.txt

Arch Linux
gcc 10.2.0
rtl-sdr 1:0.8.0-1
soapysdr 0.7.2-3
soapyrtlsdr 0.3.0-2

Disabled all the backends except RTL-TCP and soapy in the cmake config. I don't have a dongle on me at the moment, so I'm not sure if missing that is causing the crash. Just wanted to check out the GUI.

I don't understand why it says me to upgrade libusb. I just installed fresh zadig.
Any help?

SDR's such as the SDRPlay RSP2 and Duo have more than one antenna input.
ability to set the input would be handy.

Hi,

I've created a rather rudimentary band plan for germany. Covers all amateur radio bands from 2.2km to 13cm as well as FM broadcast. Some license-free stuff like CB, PMR, etc. is also there.

I just tried compiling SDR++ on Debian.

There seems to be a problem with the source code:

I did as told and changed the lines 146, 246 and 342 and then it compiled.
I am still experiencing some problems (which might be related to this), but I will open another case for this later.

I have installed sdrpp_v0.2.5_beta_preview_x64.zip. When executing I get errors as indicated in the attached screen dump.
I have also downloaded the source code, rebuilt it and get the same errors when executing.
Please could you advise how to get past this problem

Nevermind

It is a very good idea to write an application! More open source multi-platform SDR apps required

1. Please add instructions for building your app for OSX. I can participate and collect on my computer under your guidance.

2. I would also like to see tabs for frequencies. Something similar to the implementation in sdr # or gqrx with spectrum highlighting.

Just taking SDRPlusPlus for a test spin. Built from latest source today on Ubuntu 20.04.

GUI comes up great, I can see the BladeRF and it does work with the default bandwidth selections. What's interesting is that if I select the 4-12M range I get no audio, at least on WFM in the FM range. Before and after the 4-12 range, all the way up to 60+M I can get audio.

I then close sdr++ and open up CubicSDR built from source and select the same 4-12 range and I get audio. No idea the difference, but figured I'd share. I've not tested SDR++ with any other SDRs yet.

Can I have a link to download volk and soapysdr dll? I can't find them.

Hi!

I just downloaded and compiled the Github repo -- however, I seem to be unable to run SDRPlusPlus after a successful compile on Ubuntu 20.10 (amd64):

$ ./sdrpp -r ../root_dev/

If I run sdrpp alone, I get the same error, but without the config file warning:

All help appreciated!

PLEASE add Antenna Power for the HackRF if it's not already included (didn't see it in your GitHub code)! This is the one thing I really hated about SDRSharp. The HackRF has an antenna power feature, and other programs use it, but SDRSharp never did.

Hi
i'm running ubuntu 18.04 with kernel 5.4 on intel core-i3 350m without dedicated graphic card
downloaded your provided .deb file release v0.2.5 _beta PREVIEW #3
followed your install guide
when i run sdrpp it says sdrpp: error while loading shared libraries: libGLEW.so.2.1: cannot open shared object file: No such file or directory
checked my libraries ans saw libGLEW2.0 is installed (shipped with ubuntu 18.04)
then compiled glew repository v2.1.0 [although newer version 2.2 is available but i compiled version 2.1 because sdrpp said it requires version 2.1]
glew makefile by default will takes the compiled .so file into /usr/lib64 so added that temporary with export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64
now when i run sdrpp will get this error:

[2021-03-28 20:08:30.178] [info] SDR++ v0.2.5_beta

after searching about this problem i didn't get what's wrong or incompatible, and here is my glxinfo |grep "OpenGL version" output : OpenGL version string: 2.1 Mesa 20.0.8

Any help appreciated!

I just saw on twitter that you started working for support for the RX888.

I am not sure if you are aware that I wrote a low level library for Linux for both the old firmware (ExtIO dll version 0.X) and the most recent firmware version (ExtIO dll version 1.X).
The version for the old firmware is here: https://github.com/fventuri/RF103 (should work for HF; still being tested for VHF/UHF)
The version for the new firmware is here: https://github.com/fventuri/libsddc (I pushed it out only a couple of days ago; it is being tested these days).

Since they are both libraries that only depend on libusb 1.0, I thought you might be able to use them in your code (or at least take a look at the code to see how things work there).

Feel free to ask me any question about them, and congratulations for your nice SDR program!

I just compiled SDR++ v0.2.5_beta PREVIEW #2 on my Raspberry Pi 4 and while the compile appears to have worked, I noticed a few things:

1. The workaround suggested in issue #39 was also necessary on the Raspberry Pi 4. The SDR hardware is a NeSDR Smart (RTL-SDR) and the Linux version on my Raspberry Pi is:

2. The CPU load on the Raspberry Pi 4, overclocked to 1.8Ghz, is fairly high (above 85%) and I am getting a series of
   ALSA lib pcm.c:8424:(snd_pcm_recover) underrun occurred
   errors.

Also the software appears to have problems with the high sample rates, e.g. at 2.048 msps the audio becomes very stocky and distorted. In comparison CubicSDR runs cleanly at 2.56 msps and causes a CPU load of about 45 to 50%.

3. I just tried to restart sdr++ and am now getting the following messages:

When I build the last 0.2.3 alpha and try to start I got:

terminate called after throwing an instance of 'std::filesystem::__cxx11::filesystem_error'
what(): filesystem error: directory iterator cannot open directory: No such file or directory [../bandplans]
Abandon (core dumped)

I start it from where I build, and there is actually a bandplans folder.

If think it should look for ./bandplans instead of ../bandplans because if I copy the folder to ../ sdrpp actually starts.

(not have you email so do this)
Will be possible in near future decoders like gr-gsm, LTE, Iridium, inmarsat voice, tetra (linux version) and many others using SDR++ as frontend? This will be a very, very large step forward and leave others SDRsoftware very far behind.

Hi,
I have compile the program from source (7759de9), everything is ok. But when I try to run the program, it just crash. the error message is here:

RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,1), Device or resource busy.

How can I fix it? thx

Installed the prerequisite package list (includinglibvolk2-dev) but when I run it, it's missing the v1 libvolk library.....

sdrpp: error while loading shared libraries: libvolk.so.1.4: cannot open shared object file: No such file or directory

I have a Debian 10 system and I see that it does include the v1 library (libvolk1-dev/stable) so this is specific to Ubuntu 20.04 and 20.10.

Hi,

after having everything compiled, I tried to open a stream with my pluto, but as soon as I hit the play button,
everything crashes.

In the log I can find various warnings and errors regarding ALSA, but there seems also to be a problem with the plutosdr_source.co

using recent binary release

SDR++ compiles fine, when invoking ./sdrpp I get the following error

Any ideas on how to proceed?

It is sometimes a nice bonus.
