Please mention in the readme, that also this package should be installed in Ubuntu:

sudo apt-get install libqwt-qt5-dev

otherwise compiling will stop with the following error:

/usr/bin/ld: cannot find -lqwt-qt5

Hi Jan,

Not a issue but a short question: Do you know how to send samples (sdr, raw or eti) to rtltcp for other programs on the same machine under Windows?

I thought about analysis with the very great DAB Player from Andreas Gsinn which has Inputs for DABstick, Airspy and Rtltcp, but not for files like your (also great) programs.

Actulal version from git has sound problems again, I have also old sdr-j .9985 and sound is ok.

I have been unable to compile versions since late September, including latest.

I have tried every possible library path for all QWT, absolutely none work. I have installed all possibilities in turn from the software database.
I have started from scratch several times now following all instructions given to the letter.

I can't get make install to work on Linux. Is it even supported?

Hi Jan and other followers !

Attempting to compile the snapshot as at 21/09/2017.

I have commented out rtl-sdr and airspy to leave dabstick, and attempting cmake using Qt5 on Raspbian Stretch.

At around 56% of the subsequent make compilation. in module src/backend/data/motdatabuilder.cpp an error is generated as it is unable to include epgdec.h ( from includes/backend/data/epg ).

I added the required lines into my CMakeList.txt to include the directory and header. The includes file once read, itself found an error, that it could not include qdom.h, which is in QtXml package. I tried including a findpackage for QtXml at the start of my CMakeList.txt, but this command was rejected by cmake.

I am sure that this is my lack of knowledge of cmake. I would be really grateful of any advice about the coding required to get QtXml discoverable by "make" at the above point.

Thank you for any comments

I converted an sdr file (s16le) to raw (u8) with

sox -e unsigned-integer -r 240000 -t raw -c 1 -b 16 /home/andreas/10c_dabmedia.sdr -t raw -e signed-integer -b 8 -r 240000 /home/andreas/10c_dabmedia.raw

Both are working in qt-dab and eti-frontend, indeed.

But I don't see any advantage in using sdr as the filesize is exactly 2x a raw file:

andreas@andiE535:~$ ls -l 10c_dabmedia.???
-rw-rw-r-- 1 andreas andreas 298197014 Apr 18 23:40 10c_dabmedia.raw
-rw-r--r-- 1 andreas andreas 596394028 Apr 17 18:45 10c_dabmedia.sdr

Maybe you can convince me to continue writing sdr files ;-)

Getting this error on make:

DAB on the raspberry pi 3, is intermittent. I've had anywhere between 1 minute and 15 minutes audio before it just grinds to a halt. It appears that the CPU remains high at 60% yet no audio.

If you can direct me how to test and provide feedback, I will. No errors that I've seen. No crashes. Just a stop in audio.

I'm using a Nooelec NESDR SMART device. Not entirely convinced by it. But reviews say it's just as good as the RTL SDR dongle from rtlsdr.

Thanks
Simon

Jvan, thanks for qt-dab!

I've managed to compile it on Debian Stretch (testing):

• Qt4:
  • install libqwt-dev
  • qt-dab.pro: LIBS += -lqwt
  • QT_SELECT=4 qmake qt-dab.pro
  • make
• Qt5:
  • install libqwt-qt5-dev
  • qt-dab.pro: LIBS += -lqwt-qt5
  • QT_SELECT=4 qmake qt-dab.pro
  • make

(just in case someone would need for reference)

Using dabstick, channels are found but I get no sound. RAW data can be saved, but not audio file. Technical info looks like:

What are minimal prerequisites to decode/play audio? (And what do these 4 horizontal bars mean?)

Thanks,
Andrey

Hi Jan, I guess in the README we should add

sudo apt-get install qtbase5-dev

for RPI3 users otherwise there is a Qt5Core error

Hi,

I use the windows version and it works great. Can you add a save settings button>? Everytime I start then i have to assign again all the sound and dabstick settings. Also if I select audio output ASIO4ALL then the program crashes. And maybe add a volume slider so I can change the volume in the program instead change the main PC volume.

Furthermore, the GUI is kind of messy, too much info and not beautifull. You might can creat6e a expert and a normal GUI (simplified) setting. Also I dont like al the sepperate windows.
Resizing the current windows dont work, get rid of that option or make it work :)

It need a lot improvements but so far I like it. Keep up teh good work.

desktop file and icon are missing for Linux. Please provide some, so that we can get it to show up in the menus.

It seems never versions produce drop-out after inserting the CPU meter.

Seems the texts in brackets in the "file open" or "file save" window are not displayed. See radio.cpp, lines 497, 1218, 1233, 1248, 1461 and 1496.

For example:

tr ("iq data (*.iq)"));

I also tried escaping, but then there is a compiler warning ...

warning: unknown escape sequence: ')'

Hi,
Today I see slides show for first time, but new window always popup avery image change on top of all others apps, this is very annoying.
Regards

hello,
can't compile after yesterday update. Previously (5 days ago) used to work.
/tmp/ccoKIXXi.ltrans2.ltrans.o: In function RadioInterface::qt_static_metacall(QObject*, QMetaObject::Call, int, void**)': :(.text+0x686): undefined reference toRadioInterface::showCoordinates(float, float)'
collect2: error: ld returned 1 exit status
Makefile:395: recipe for target 'linux-bin/qt-dab-0.999' failed

Just curious what it could be, where I'm doing wrong? Doing this on odroid (clone of Raspberry)

I know it was me giving you the hint how to get the temp folder under Windows (%tmp%). But it seems you should use the following function in C++ to get it. Currently qt-dab does not write slides

cannot write file %tmp%\qt-pictures\file.png

https://stackoverflow.com/questions/8087805/how-to-get-system-or-user-temp-folder-in-unix-and-windows
https://msdn.microsoft.com/en-us/library/windows/desktop/aa364992(v=vs.85).aspx

A user has posted a very weak raw file (please rename it to raw) which is indeed a ghost frequency of 12C on 44 MHz, but the strange thing is, when you compare eti-stuff and qt-dab in parallel (see screenshot), you will see 11 services found in eti-frontend, whereas Qt-DAB finds just 6 services.

I have Git master up-to-date as at 2017-02-14T07:53+00:00 and am using the CMake build. I am getting an error:

Hi,

Is possible to use dab-cmdline with this https://github.com/Opendigitalradio/dablin together? Or in future?

Regards

Hi,

At time the RTL-TCP port is fixed to 1234... however this port can be in use in the server.

It's possible to support an user configurable port?

Thank you!

Currently it seems, using the CMake build, that install happens to a place other than $prefix/bin.

I get

DAB stick not found! Please use one with RTL2832U or similar chipset!

I tried running Qt-DAB as normal user and as root (to exclude the possibility of missing permissions).

When a user plays a rawfile (sdr, iq or raw), then these Menu items don't make sense:

1. Scan band
2. VHF/L-Band switch
3. Mode 1-4
4. Channel
5. in Technical Details: frequency

So you could set them inactive.

https://www.welle.io/devices/rawfile#record-an-u8-raw-file describes how to create a raw file and the mentioned script uses iq as file extension.

So I propose to add this file extension to the open file window.

Hi,

I'm hoping that some could help with the error below?

Thanks

Pressing "Save audio" or "dump to raw file" opens a file dialog. But if you then press cancel it does not cancel, but writes a file ".wav" resp. ".sdr" anyway. You can only stop recording by pressing "WRITING" again.

Would it be possible to set the text "WRITING" in red color (see audioDumpButton and the dumpButton)?

This issue is also valid for eti-stuff.

The "Autogain" setting for dabstick is saved in ~/.qt-dab.ini but is not restored on next invocation of qt-dab.

The value saved looks like: "autogain=autogain on"

The software is running on Debian GNU/linux (testing) amd64 with Nooelec nesdr. qt-dab was downloaded 9th Mar 17.

N.B. It might be helpful to default this setting to "on" as the receiver does very little with autogain off.

I have compilation error:

Hi,

I noticed that there are several image files (like slide11.jpg slide22.jpg slide91.jpg slide94.png ) that are provided by the radio stations and shown by qt-dab. Most of them are in the same directory like were the binaries are located (linux-bin folder). However I also found one image in my home directory (most likely because I started qt-dab from there using ~/Programms/qt-dab/linux-bin/qt-dab-0.999 ). Most of these images are corrupt, therefore these files might be leftovers for cases were I had to kill the program (e.g. because I lost the connection to my Raspberry). Anyway I would strongly prefer if these (temporary) images would be placed in some temporary folder (like /tmp/qt-dab ) and not all-over the place. Or is this a side effect of my usage of the -T option to analyse the frame drops?

Hi,

Almost got all the QT/Qwt stuff compiled except ld fails looking for a file called -lqwt-qt5.
I can find no reference online to this file. What is it?

The app. does work if I don't include spectrum, so i guess its todo with that.

/usr/bin/ld: cannot find -lqwt-qt5

Please use QApplication::setWindowIcon() so that the application, when launched from the AppImage, will show an icon in the dock.

I'm using Qt-DAB mainly for prerecorded files.

But it seems (obviously since some versions) that when I chose a raw/iq/sdr file at the start the same window appears again and I have again to specify the file name.

I can't compile from git:

CMake Error at CMakeLists.txt:506 (add_executable):
Cannot find source file:

In fib-processor.cpp I found protlevel 0, 1, 2, and 3, but the best protection level is 1A, not 0A.

That's why an EPG or TPEG (Slovenia, Vienna, Italy) shows

data: protlevel = 2

instead of 3.

So you should add 1 for the output.

Hint: The output in the "Technical Data" window is - on the other hand - correct for all audio services.

Latest release refuses to compile, previous releases were able to compile.

Hi

I have suggestion for fft view to change end lever form -40 to -30 when dabstic is used.

Regards

Whilst the CMake build works fine on Fedora Rawhide, it fails on Debian Sid. The problem is that Sid does not have Qt5Declarative. Instead it seems to have Qt5Quick. The line:

find_package (Qt5Declarative REQUIRED)

works fine on Rawhide, but has to be replaced with:

find_package (Qt5Quick REQUIRED)

to get a build on Sid.

I found out that the slideshows in qt-dab and eti-stuff don't work at all in Slovenija and in Slovakia, whereas dablin_gtk or XPADxpert (and the DABPlayer from Andreas Gsinn under Windows) show them.

BTW: In Vienna it worked under qt-dab well on the same Laptop, see screenshot: .

According to XPADxpert it's in the same subchannel.

See the (zipped) eti-file http://andimik.bplaced.net/temp/10d_lang2.eti.zip , please load in eti-backend, tune to the English speaking "Slo Int Radio SI" (other programs didn't have slideshows at that time and the sample is too short).

I'm using qt-dab with an dabstick on my RaspberryPi.
If I start the gui, change the channel, listen to some music and then quit the program by clicking the "quit" button I get

ofdm decoder is closing down now
Termination started
closed
Segmentation fault

I don't know if the segmentation fault is the reason why the channel in the ~/.qt-dab.ini is not being updated. Of course I can update the channel in the file manually, however I would prefer if the last used channel is automatically saved. The other values (device and soundchannel) were properly updated.

Seems the slideshows in the appimage do not work. I only get a very small window without the slide.

instead of the slide. The console output is

going to show picture img01.jpg
going to write file /tmp/qt-pictures/img01.jpg

The same release (d293dbf) built with Qt-Creator works well.

I guess this is the same problem as under Windows:

going to show picture
setGeometry: Unable to set geometry 5x13+363+124 on QWidgetWindow/'QLabelClassWindow'.
Resulting geometry: 120x13+363+124 (frame: 8, 31, 8, 8, custom margin: 0, 0, 0, 0, minimum size:
0x0, maximum size: 16777215x16777215).

Fedora Rawhide has now updated to Qt 5.9 beta 3. This introduces that it is not possible to build with the current CMakeFiles.txt. The problem appears to be the naming of the Qt5Declarative package which is no longer present. As with Debian Sid, the name is now Qt5Quick. So with:

#if(LSB_ID_SHORT STREQUAL "Debian")
	find_package(Qt5Quick REQUIRED)
#else()
#	find_package (Qt5Declarative REQUIRED)
#endif()

things built again. I am not sure what a proper solution to this is.

Maybe I'm missing an obvious solution, but is there a way to stop the playback of music without closing the complete program (I assume that setting the gain in the extra windows to 0 would still use resources?)
Instead of adding an extra button one could maybe think about toggling the "start" button to a "stop" button while music is being played?
(Just as a side question, what is the difference between the "Start" and the "Scan band" button?)
