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 1 to make the Alsa audio code write zeros  to  the  audio  device
              when  there  is no audio to write available. This may be needed for some audio devices that take a
              long time to recover from an underflow condition.

       HOME   Used to find the per user configuration file.
