rtl_sdr

Raw data recorder for RTL-SDR receivers.

Data is encoded using I/Q sampling (aka quadrature sampling).

• Save RAW data from a frequency (specified in Hz) to a file:

rtl_sdr -f {100000000} {path/to/file}

• Pipe data to another program:

rtl_sdr -f {100000000} - | {aplay}

• Read a specified number of samples:

rtl_sdr -f {100000000} -n {20} -

• Specify the sample rate in Hz (ranges 225001-300000 and 900001-3200000):

rtl_sdr -f {100000000} -s {2400000} -

• Specify the device by its index:

rtl_sdr -f {100000000} -d {0} -

• Specify the gain:

rtl_sdr -f {100000000} -g {20} -

• Specify the output block size:

rtl_sdr -f {100000000} -b {9999999} -

• Use synchronous output:

rtl_sdr -f {100000000} -S -
