ARLA/CLUSTER: SDR barato baseado numa placa DVB-T (já receberam TETRA e GMR com ela!!!)

[Pedro Ribeiro - CR7ABP]

  rtl-sdr

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 Antti 
Palosaari 
<http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/44461/focus=44461>. 



    Specifications

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 *2.8 MS/s*. The 
frequency range is highly dependent of the used tuner, sticks that use 
the Elonics E4000 offer the best range (64 - 1700 MHz).


    Supported Hardware

So far, the following devices are supported:

  * ezcap EzTV668 USB 2.0 DVB-T/DAB/FM stick (Elonics E4000 tuner)
