This page is about configure software defined radio (SDR) using the infamous RTL2832U RealTek chip. Start by ordering something off ebay that has the RTL2832U chip. In my case, I have the R820T which I got with shipping for about $10USD.

On OSX in terminal

This uses homebrew which you should have installed

brew install cmake
git clone git://
cd rtl-sdr/
mkdir build
cd build
sudo make install

and that's it, you should now be able to try it.


which should make sure you device is detected; make sure you have no errors. After that, try regular FM radio using rtl_fm:

rtl_fm -W -f 89.1M | play -r 32k -t raw -e signed-integer -b 16 -c 1 -V1 -
