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.
