received from Juha Vierinen: A student here noticed that there is dc bias even with the rafael tuner. We looked into this issue and found that using 127.4f instead of 127.5f removes this bias. I assume this is associated with a bug in the digital downconversion of the RTL chip. This change fixes the problem.

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
* Great Scott Gadgets HackRF through libhackrf
* Ettus USRP Devices through Ettus UHD library
* RTL2832U based DVB-T dongles through librtlsdr
* RTL-TCP spectrum server (see librtlsdr project)
* MSi2500 based DVB-T dongles through libmirisdr
* gnuradio .cfile input through libgnuradio-blocks
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://git.osmocom.org/gr-osmosdr
sudo make install
NOTE: The osmocom blocks will appear under 'Sources' and 'Sinks' categories
in GRC menu.
