It looks like there are two options for installing an up-to-date gnuradio on ubuntu:
 
  
−
1) use an install script
+
mkdir /usr/local/src/SDR
−
2) install from source
+
cd /usr/local/src/SDR
  
−
Don't ask me why, but I tried the second option (probably the harder). After a first attempt that failed, I went for the first (and recommended option) to much success! So... lesson learned. Note to self, follow advice of program developers when installing software.

Latest revision as of 09:45, 16 October 2012

It was recently discovered that several cheap DVB-T usb dongles could be configured to be used as cheap ham radio receivers. Follow along with the discussions here: http://www.reddit.com/r/rtlsdr or find some of the useful software here: http://sdr.osmocom.org/trac/wiki/rtl-sdr

I picked up one of the compatible receivers from ali-express: http://www.aliexpress.com/snapshot/106450763.html

and will document here the steps I took to set it up with gnuradio on ubuntu 12.04.

There are a few things that I won't cover in this instructable, because they deserve an instructable of their own. These include:

1) using the Ubuntu command line (terminal) 2) cloning a git repository 3) building software from source on Ubuntu (especially with cmake)

If anyone has links to stellar, class A++ quality tutorials on any of these things, please add them to the comment and I will link them here.

Setup udev rules

Next, you need to add some udev rules to make the dongle available for the non-root users. First you want to find the vendor id and product id for your dongle.


Create a new file as root named /etc/udev/rules.d/20.rtlsdr.rules that contains the following line: 

SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", GROUP="adm", MODE="0666", SYMLINK+="rtl_sdr"

With the vendor and product ids for your particular dongle. This should make the dongle accessible to any user in the adm group. and add a /dev/rtl_sdr symlink when the dongle is attached.

It's probably a good idea to unplug the dongle, restart udev (sudo restart udev) and re-plug in the dongle at this point.
