* I did this on debian jessie which at the time has gnuradio v 3.7.3-9+b1 and rtl-sdr v 0.5.3-3
* I'm having a lot of trouble getting gqrx working on debian wheezy even with backports. Whereas the backports versions of gnuradio, rtl-sdr and gqrx-sdr install just fine, when running gqrx I get the following error:
* gqrx won't work on debian wheezy systems with 2 Gb of memory for some reason. I get the same error as is shown in this post: https://groups.google.com/forum/#!topic/gqrx/20F8RMWkNbUgqrx: symbol lookup error: /usr/lib/x86_64-linux-gnu/libQtNetwork.so.4: undefined symbol: _ZN16QIODevicePrivate13putCharHelperEc
I recently bought a DVB USB dongle based on RTL2832 and R280T: http://www.ebay.com.au/itm/221450623699?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649. AU$11for a TV card which actually works flawlessly under linux really isn't bad!
As I already have a mythtv setup using leadtek DTV 1000S I was more interested in exploring the R820T dongle as a software defined radio (SDR).
So, after glancing at http://www.thepowerbase.com/2012/06/getting-started-with-rtl-sdr/2/ I did the following
sudo apt-get install rtl-sdr gnuradio gnuradio-dev libgnuradio-osmosdr0.1.1.4 git libboost-dev liblog4cpp5-dev libboost-system-dev libboost-program-options-dev checkinstall mkdir ~/tmp cd ~/tmp git clone https://github.com/csete/gqrx.git gqrx.git cd gqrx.git/ mkdir build cd build qmake ../ make sudo checkinstall --install=no0 - Maintainer: [ root@niobium ] 1 - Summary: [ gqrx ] 2 - Name: [ gqrx ] 3 - Version: [ 20140726 ] 4 - Release: [ 1 ] 5 - License: [ GPL ] 6 - Group: [ checkinstall ] 7 - Architecture: [ amd64 ] 8 - Source location: [ build ] 9 - Alternate source location: [ ] 10 - Requires: [ ] 11 - Provides: [ build ] 12 - Conflicts: [ ] 13 - Replaces: [ ]sudo dpkg -i gqrx_20140726-1_amd64.deb
Starting gqrx and using it is easy:
