||
.SH NAME
|
||
rtl_tcp \- an I/Q spectrum server for RTL2832 based DVB-T receivers
|
||
.SH DESCRIPTION
|
||
Uses a re-purposed DVB-T receiver as a software defined
|
||
radio to receive and send I/Q data via TCP network to another
|
||
demodulation, decoding or logging apllication. Written for
|
||
and incorporated into the osmocom rtl-sdr project.
|
||
.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
|
||
Run this program on a machine with an rtl-sdr supported
|
||
device connected and it will provide I/Q data to other applications
|
||
via TCP/IP.
|
||
.SH SYNOPSIS

|
||
.IP "-g gain (default: 0 for auto)"
|
||
.IP "-s samplerate in Hz (default: 2048000 Hz)"
|
||
.IP "-b number of buffers (default: 32, set by library)"

.LP
|
||
Use the device argument 'rtl_tcp=10.0.0.2:1234' in OsmoSDR (gr-osmosdr) source
|
||
to receive samples in GRC and control rtl_tcp parameters (frequency, gain, ...).
|
||
.LP
|
||
use the rtl_tcp=... device argument in gr-osmosdr source to receive
|
||
the samples in GRC and control the rtl settings remotely.
|
||
.LP
|
||
This application has been successfully crosscompiled for ARM and MIPS
|
||
devices and is providing IQ data in a networked ADS-B setup at a rate
|
||
of 2.4MSps. The gr-osmosdr source is being used together with an
|
||
optimized gr-air-modes version (see Known Apps below). It is also
|
||
available as a package in OpenWRT.
