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)

Example:

       rtl_tcp -a 10.0.0.2 [-p listen port (default: 1234)]
               Found 1 device(s).
               Found Elonics E4000 tuner
               Using Generic RTL2832U (e.g. hama nano)
               Tuned to 100000000 Hz.
               listening...

       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.

       A use case is described ​https://sites.google.com/site/embrtlsdr/
