<p> DVB-T sticks based on the Realtek RTL2832U can be used as a
cheap SDR, since the chip allows transferring the raw I/Q
samples to the host, which is officially used for DAB/DAB+/FM
demodulation. The possibility of this has been discovered by the
V4L/DVB kernel developer <a moz-do-not-send="true"

<p> The RTL2832U outputs 8-bit I/Q-samples, and the highest
theoretically possible sample-rate is 3.2 MS/s, however, the
highest sample-rate without lost samples that has been tested so
far is <b>2.8 MS/s</b>. The frequency range is highly dependent
of the used tuner, sticks that use the Elonics E4000 offer the
best range (64 - 1700 MHz). </p>
