gr-dab's Issues

Reference recordings

Would it be possible to include one or two brief capture of an actual DAB broadcast from a real station along with the example flowgraphs? I don't have a way to get a direct capture in the U.S., and the only links I can find to uploaded captures are dead.

Calling yaml.load() without Loader=... is deprecated

When running grdab (which is by the way working perfectly), I get this:

/usr/local/lib/python3/dist-packages/grdab/app/config.py:20: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  self.adjust_config = yaml.load(ymlfile)

Using DAB with RTL-SDR Source

Hello,

is it possible to use your dab-receiver with a RTL-SDR Source instead of the USRP?

This brings me to my next question, how to use your application? And is it possible to demodulate and listening DAB-Radio in realtime?

Best regards & thanks in advance

installation error through pybombs

Hi, I'm installing gr-dab with the command pybombs install gr-dab and I get the following error
[ 95%] Generating adjustment_gui.py

Cannot import gnuradio.

Is the model path environment variable set correctly?
All OS: PYTHONPATH

Is the library path environment variable set correctly?
Linux: LD_LIBRARY_PATH

Compilation error with gcc-11

I'm trying to compile gr-dab on Arch Linux (gcc-11.1.0, gnuradio-3.8.2.0), but I'm getting an error which, I suppose, is caused by the stricter requirements of gcc-11.

gr-dab for gnuradio 3.7

Hi,
I have tried to compile gr-dab block and there is configure problem as it is looking for gr-core module of gnuradio. With gnuradio 3.7 there was redesign of modules thus there is no gr-core.

Is there a glipse o hope to see this block updated to gnuradio 3.7 specs?

support Gnuradio for v3.9.0

gr-dab FTBFS with fedora rawhide , seems is the same problem of

drmpeg/gr-dvbs2rx#10
drmpeg/gr-dvbs2#7

wrong python dist-packages location

I do not know if this is specific to my system (maybe it's broken), but sudo make install installs the python module to:
/usr/local/lib/python3/dist-packages/grdab, which is not in my python packages path (this results in a ModuleNotFoundError: No module named 'grdab'):

➜  ~ python3 -m site
sys.path = [
    '/usr/lib/python39.zip',
    '/usr/lib/python3.9',
    '/usr/lib/python3.9/lib-dynload',
    '/usr/local/lib/python3.9/dist-packages',
    '/usr/lib/python3/dist-packages',
    '/usr/lib/python3.9/dist-packages',
]

I think this is because in cmake, ${CMAKE_INSTALL_PREFIX} defaults to /usr/local, so the cmake_install.cmake files have the line:

file(INSTALL DESTINATION "${CMAKE_INSTALL_PREFIX}/lib/python3/dist-packages/grdab" TYPE FILE FILES

again, this sounds like a problem on my system (Kubuntu 21.10 x86_64.), but maybe other people are having similar problems ?

DAB+ receipt on macbook

Hi,

could you help me and prepare a Mac Ports version of DAB+ receiver/transmitter software?

best,

GNURadio 3.8 support

GNURadio 3.8 brings Python 3 support. Linux distro's are dropping Python 2 packages, because Python 2 is near EOL. E.g. in Fedora Rawhide (f32) all Python 2 packages without FESCO exception were mass orphaned. GNURadio 3.8 support is needed to keep this package in the distros.

I tried to do some initial (but not optimal) porting, but it's more complex task. I have still problems with the GRC flowgraphs. My initial attempt:
https://jskarvad.fedorapeople.org/gr-dab/gr-dab-0.3-python38.patch

Boost required to compile dab

I'm trying to build gr-dab on my debian system. On running cmake ../ I get the following output:

$ cmake ../
-- Build type not specified: defaulting to release.
-- Could NOT find Boost
CMake Error at CMakeLists.txt:63 (message):
  Boost required to compile dab


-- Configuring incomplete, errors occurred!
See also "[…]/gr-dab/build/CMakeFiles/CMakeOutput.log".

but libboost-dev (version 1.55.0.2) is installed. There are some more libboost packages, but which is needed?

Constellation map sometimes get broken

Hi, I'm using gr-dab module to watch for constellation diagram of the modulated signal. But I found that diagram - is not stable from real hardware.

After that to make sure that module working properly, I used modulator's direct I/Q output as source for decoder. But unfortunaly that won't help. Neither dab_rx_constellation.py (with file input) nor GRC graph works for me:

The source file has been generated by ODR-DabMod using commandline:
odr-dabmod test.dump.eti -g 2 -m 1 -f test.dump.eti.mod.raw

The problem, that sometimes constellation became broken like this:

Tuning parameters like filtering, equalisation, correcting ffe and samplerate won't help. Anyway they are not needed for direct modulated input, since they are not yet distorted.

Segfault on Fedora 29 when tuned to DAB station

Versions used:

gr-dab-0.3

I ran:

grdab adjust

Tuned to 229.072, where the local DAB transmitter is and the grdab immediately crashed. This is 100% reproducible. I Tried to tune to Brno Hady (12D channel) in Czech Republic. Backtrace:

Without DAB signal it works, i.e. runs and not crashes.

gr::log :DEBUG: fib_sink_vb0 - FIB CRC error

grdab info doesn't decode anything - instead, it continually spews the above error message. The command that I run is 'grdab info -f 227.36', as channel 12C is what's in use all over our country (NL).

Setup: gnuradio 3.8.2, uhd 4.0, gr-osmosdr 0.2.3, Ettus B210

grdab adjust mostly works. The DAB signal is clearly received, but the noise level outside of the signal keeps going up and down, and with it, the constellation goes from bad to good, and vv. This happens with a rate of about one cycle per second. Changing the PPM value has little effect as long as it's roughly around 0.

Welle.io picks up the DAB+ stations without any issues, showing a 13dB SNR, and no RS or AAC errors. PPM offset is reported as 1.15 ppm (-262 Hz)

Missing blocks for DAB transmitter

Hey, I managed to install gr-dab without error but when launching GNU radio im able to put only:
DAB +Audio decoder
DAB Coarse Frequency Correction
DAB Demultiplexer
DAB Differential phasor
DAB FIC Decoder
DAB Frequency Intervealer
DAB OFDM Demodulator
DAB OFDM Synchronization

Only those mentioned blocks have their .yml files in gnuradio /usr/local/share/gnuradio/grc/blocks installed, the rest of block dont have them installed there and GNU radio is saying block missing when loaded example of DAB transmitter. Can you help me, because im green in fixing this issue.

Best regards
