rtl-sdr is a project to enable DVB-T sticks based on the Realtek RTL2832U to be used as a cheap Software Defined Radio (SDR), since the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation.

I picked up a couple of Unikoo UK001T cards, based on reddit’s guide to functional chipsets.

rtl-sdr is a command line tool that can initialize the RTL2832, tune to a given frequency, and record the I/Q-samples to a file.

The code can be checked out with:

git clone git://git.osmocom.org/rtl-sdr.git

Additionally, a source block for GNU Radio is being worked on.
