Basics

Required packages:

rtl-sdr Main SDR driver and utils.
Important note: It disables buil-in drivers for DVB-T and after installation programs to watch TV don't work.
gnu-radio
GQRX Useful program to work with SDR, has GUI with signal spectrum.
qwt Additional libraries for Qt. It is used by GNU Radio and some widgets don't work without it (don't print clear message)

I have up-to-date Linux and RTL 2838 and I don't need to replace any drivers, all works out of the box.

Diagrams

my-first-sdr.grc - simply FM radio using SDR

Utils

rtl_test - low-level simply tool from rtl-sdr to test the sdr. If program displays "Supported gain values" then SDR is probably configured correctly.
