+.TH "rtl_sdr" 1 "0.5.0" RTL-SDR "User Commands"
+.SH NAME
+rtl-sdr \- an I/Q recorder for RTL2832 based DVB-T receivers
+.SH 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.
+.LP
+In-Phase and Quadrature Phase data can faithfully represent
+all of the information in a band of frequencies centered
+on a carrier signal frequency.
+.LP
+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.
+.LP
+Because most of the RTL2832 devices are connected using USB, the
+librtlsdr library depends on the libusb library to communicate with
+the device.
+.SH USAGE
+This program captures information from a band of frequencies
+and outputs the data in a form useful to other software radio
+programs.
+.SH SYNOPSIS
+.B rtl_adsb [-f freq] [OPTIONS] [output file]
+.SH OPTIONS
+.IP "-f frequency_to_tune_to [Hz]"
+.IP "-s samplerate (default: 2048000 Hz)"
+.IP "-d device_index (default: 0)"
+.IP "-g gain (default: 0 for auto)"
+.IP "-p ppm_error (default: 0)"
+.IP "-b output_block_size (default: 16 * 16384)"
+.IP "-n number of samples to read (default: 0, infinite)"
+.IP "-S force sync output (default: async)"
+.IP tfilename
+ (a '-' dumps samples to stdout)
+.SH EXAMPLES
+.IP "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
+.LP
+to record samples to a file or to forward the data to a fifo.
+.LP
+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).
