= OSMOCOM Gnuradio Source =
While primarily being developed for the OsmoSDR hardware, this block as well supports:
- [http://tetra.osmocom.org/trac/wiki/Funcube_Dongle FunCube Dongle] through libgnuradio-fcd
- [http://sdr.osmocom.org/trac/ OSMOCOM OsmoSDR] Devices through [http://cgit.osmocom.org/osmo-sdr/ libosmosdr]
- [http://greatscottgadgets.com/hackrf/ Great Scott Gadgets HackRF] through [https://github.com/mossmann/hackrf libhackrf]
- [https://www.ettus.com/product Ettus USRP] Devices through [http://files.ettus.com/uhd_docs/manual/html/build.html Ettus UHD library]
- RTL2832U based DVB-T dongles through [http://sdr.osmocom.org/trac/wiki/rtl-sdr librtlsdr]
- RTL-TCP spectrum server (see librtlsdr project)
- MSi2500 based DVB-T dongles through [http://cgit.osmocom.org/libmirisdr/ libmirisdr]
- gnuradio .cfile input through libgnuradio-core
By using the OsmoSDR block you can take advantage of a common software api in your application(s) independent of the underlying radio hardware.
Build process'''The gnuradio source requires a recent gnuradio (>= v3.6.4.1) to be installed.'''
Before building the source you have to make sure that all the dependencies (see list of supported devices above) you are intend to work with are properly installed. The build system of gr-osmosdr will recognize them and enable specific source/sink components thereafter.
Please note: prior pulling a new version from git and compiling it, please do a "make uninstall" first to properly remove the previous version.
Building with cmake:
{{{
git clone git://git.osmocom.org/gr-osmosdr
cd gr-osmosdr/
mkdir build
cd build/
cmake ../
make
sudo make install
sudo ldconfig
}}}
NOTE: The OSMOCOM source block will appear under 'Sources' category in GRC menu.
To build the API documentation:
{{{
cd build/
cmake ../ -DENABLE_DOXYGEN=1
make -C docs
}}}
Marcus D. Leech has kindly integrated the forementioned build steps into his gnuradio installation script at [http://www.sbrac.org/files/build-gnuradio]. This is the most user-friendly option so far.
Device specificationYou can specify the source or sink device using a comma separated string of argument=value pairs.
The always-up-to-date block documentation is available [http://cgit.osmocom.org/gr-osmosdr/tree/grc/gen_osmosdr_blocks.py#n100 right here].
=== IQ File Source ===file=<path-to-file-name> | |||||
freq=<frequency> | in Hz | ||||
rate=<sampling-rate> | in samples/s | ||||
repeat=true | false | Default is false | |||

NOTE: if you don't specify rtl_xtal/tuner_xtal, the underlying driver will use 28.0MHz
