rtl_sdr

Raw data recorder for RTL-SDR receivers. Data is encoded using I/Q sampling (aka quadrature sampling). More information: https://osmocom.org/projects/rtl-sdr/wiki/Rtl-sdr.

• 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 -
