While primarily being developed for the OsmoSDR hardware, this block
as well supports:

* FUNcube Dongle through libgnuradio-fcd
* FUNcube Dongle Pro+ through gr-fcdproplus
* sysmocom OsmoSDR Devices through libosmosdr
* RTL2832U based DVB-T dongles through librtlsdr
* RTL-TCP spectrum server (see librtlsdr project)
* MSi2500 based DVB-T dongles through libmirisdr
* SDRplay RSP through SDRplay API library
* gnuradio .cfile input through libgnuradio-blocks
* RFSPACE SDR-IQ, SDR-IP, NetSDR (incl. X2 option)
* AirSpy Wideband Receiver through libairspy
* CCCamp 2015 rad1o Badge through libhackrf
* Great Scott Gadgets HackRF through libhackrf
* Nuand LLC bladeRF through libbladeRF library
* Ettus USRP Devices through Ettus UHD library
* Fairwaves UmTRX through Fairwaves' fork of UHD
* Red Pitaya SDR transceiver (
* FreeSRP through libfreesrp

By using the OsmoSDR block you can take advantage of a common software api in
your application(s) independent of the underlying radio hardware.

For installation and usage guidelines please read the documentation available

For the impatient :) a short excerpt:

The Gnu Radio block requires a recent gnuradio (>= v3.7) to be installed.

Before building the block 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://
cd gr-osmosdr/
mkdir build
cd build/
cmake ../
sudo make install
sudo ldconfig

NOTE: The osmocom blocks will appear under 'Sources' and 'Sinks' categories
in GRC menu.
