= Welcome to the GNU Radio Trac System =

Getting the Software and Installing It

All GNU Radio related code is now in a [http://subversion.tigris.org subversion] repository which you can browse from the "Browse Source" button above. To '''check out the latest code from the development branch''', do the following from the command line:

{{{
$ svn co http://gnuradio.org/svn/gnuradio/trunk gnuradio
}}}

If you instead wish to '''check out the latest code from the [wiki:Release3.0Branch stable branch]''', do the following from the command line:

{{{
$ svn co http://gnuradio.org/svn/gnuradio/branches/releases/3.0 gnuradio
}}}

GNU Radio consists of a number of self-contained [wiki:Components components]. The BuildGuide contains info on how to get GNU Radio up and running on your computer.

If you prefer to build from '''release tarballs''' instead of from the source code repository,
the latest can be downloaded here:

• ftp://ftp.gnu.org/gnu/gnuradio/gnuradio-3.0.3.tar.gz
• ftp://ftp.gnu.org/gnu/gnuradio/gr-howto-write-a-block-3.0.3.tar.gz

or at any of the [http://www.gnu.org/order/ftp.html GNU mirrors].

Mailing Lists and Getting Help

It is strongly recommended that everyone using GNU Radio and/or the USRP subscribe to the discuss-gnuradio mailing list. It is the proper place to ask if you have any questions or problems. Instructions on how to join can be found at the [http://www.gnu.org/software/gnuradio/mailinglists.html mailinglists] page.

To subscribe to the USRP-announce mailing list, which gets about 1 message per month with the latest news on the USRP, see [http://aeinet.com/mailman/listinfo/usrp-announce USRP Announce].

Getting the USRP and associated Schematics

USRP hardware schematics and associated files can be obtained with the following command:

{{{
$ svn co http://gnuradio.org/svn/usrp-hw/trunk usrp-hw
}}}

USRP documentation can be found [wiki:USRP here]. Detailed information on the [wiki:UsrpFPGA FPGA] is also available.
