NAME

       rtl-sdr - an I/Q recorder for RTL2832 based DVB-T receivers

DESCRIPTION

       Uses  a  re-purposed  DVB-T receiver as a software defined radio to receive signals in I/Q
       data form. Written for and incorporated in the osmocom rtl-sdr project.

       In-Phase and Quadrature Phase data can faithfully represent all of the  information  in  a
       band of frequencies centered on a carrier signal frequency.

       Much  software  is  available for the RTL2832. Most of the user-level packages rely on the
       librtlsdr library which comes as part of the rtl-sdr codebase. This codebase contains both
       the  library  itself  and  also  a number of command line tools such as rtl_test, rtl_sdr,
       rtl_tcp, and rtl_fm. These command line tools use the library to test for the existence of
       RTL2832 devices and to perform basic data transfer functions to and from the device.

       Because most of the RTL2832 devices are connected using USB, the librtlsdr library depends
       on the libusb library to communicate with the device.

USAGE

       This program captures information from a band of frequencies and outputs  the  data  in  a
       form useful to other software radio programs.

SYNOPSIS

       rtl_adsb [-f freq] [OPTIONS] [output file]

OPTIONS

       -f frequency_to_tune_to [Hz]

       -s samplerate (default: 2048000 Hz)

       -d device_index (default: 0)

       -g gain (default: 0 for auto)

       -b output_block_size (default: 16 * 16384)

       -n number of samples to read (default: 0, infinite)

       -S force sync output (default: async)

       tfilename
               (a '-' dumps samples to stdout)

EXAMPLES

       Example: To tune to 392.0 MHz, and set the sample-rate to 1.8 MS/s, use:
               ./rtl_sdr /tmp/capture.bin -s 1.8e6 -f 392e6

       to record samples to a file or to forward the data to a fifo.

       If  the  device  can't  be opened, make sure you have the appropriate rights to access the
       device (install udev-rules from the repository, or run it as root).
