This is the command rtl_tcp that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
rtl_tcp - an I/Q spectrum server for RTL2832 based DVB-T receivers
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.
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
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.
SYNOPSIS
rtl_tcp [OPTIONS]
OPTIONS
-a listen address
-p listen port (default: 1234)
-f frequency to tune to [Hz]
-g gain (default: 0 for auto)
-s samplerate in Hz (default: 2048000 Hz)
-b number of buffers (default: 32, set by library)
-n max number of linked list buffers to keep (default: 500)
-d device_index (default: 0)
-P ppm_error (default: 0)
Example:
rtl_tcp -a 10.0.0.2 [-p listen port (default: 1234)]
Found 1 device(s).
Found Elonics E4000 tuner

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, ...).
use the rtl_tcp=... device argument in gr-osmosdr source to receive the samples in GRC and
control the rtl settings remotely.
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.
