NAME

       remotetrx - The SvxLink remote transceiver application

SYNOPSIS

       remotetrx  [--help]  [--daemon]  [--logfile=log  file] [--config=configuration file] [--pidfile=pid file]
       [--runasuser=user name]

DESCRIPTION

       remotetrx is the SvxLink remote transceiver application. It is used  to  connect  to  a  receiver  and/or
       transmitter  and  then the main SvxLink server can connect to the remote transceiver server via TCP/IP to
       get audio to/from it.

       It is also possible to link via RF instead of via TCP/IP. An example use of the latter would  be  if  the
       repeater is placed in a remote location where there is no network. Then networked remote receivers can be
       linked up to the repeater via RF from a link site where network is available.

       The  setup  is pretty straight forward. The setup of a receiver or transmitter is done in the same way as
       in the SvxLink server so use the svxlink.conf(5) manual page as  a  reference  for  that.  The  remotetrx
       specific configuration is described in the remotetrx.conf(5) manual page.

       On  the  SvxLink server side you need to configure a networked receiver/transmitter. That is described in
       the svxlink.conf(5) manual  page  in  the  Networked  Receiver/Transmitter  Section.  If  using  multiple
       receivers  you also want to configure a voter and make proper calibration of the signal level detector on
       each receiver.

OPTIONS

       --help Print a help message and exit.

       --daemon
              Start the SvxLink remote receiver server as a daemon.

       --runasuser
              Start RemoteTrx as the specified user. The switch to the new user will happen after  the  log  and
              pid files has been opened.

       --logfile=log file
              Specify  a  log  file to put all output into. Both stdout and stderr will be redirected to the log
              file.

       --pidfile=pid file
              Specify a pid file to write the process ID into.

       --config=configuration file
              Specify which configuration file to use.

FILES

       /etc/svxlink/remotetrx.conf (or deprecated /etc/remotetrx.conf)
              The system wide configuration file. See remotetrx.conf(5) for further details.

       ~/.svxlink/remotetrx.conf
              Per user configuration file. See remotetrx.conf(5) for further details.

       /etc/svxlink/remotetrx.d/*
              Additional configuration files. This directory is setup by the CFG_DIR configuration variable.

ENVIRONMENT

       ASYNC_AUDIO_NOTRIGGER
              Set this environment variable to 1 if you get an error about ioctl: Broken pipe  during  remotetrx
              server startup when using OSS audio.

       ASYNC_AUDIO_ALSA_ZEROFILL
              Set  this  environment  variable  to 0 to stop the Alsa audio code from writing zeros to the audio
              device when there is no audio to write available.  ASYNC_AUDIO_UDP_ZEROFILL Set  this  environment
              variable  to  1 to enable the UDP audio code to write zeros to the UDP connection when there is no
              audio to write available.

       HOME   Used to find the per user configuration file.
