== NAME

wsjtx, jt9 - Weak signal communications program.

== SYNOPSIS

*wsjtx* ['OPTIONS']

== DESCRIPTION

*wsjtx* is a weak signal communications program supporting several operating
modes: JT65, JT9, JT4 and WSPR (*wsjtx* version 1 supported JT9 only).

WSJT-X home page:: http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.html

WSJT-X User's Guide::
http://www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main-{VERSION}.html

An alternative JT65 decoder executable *kvasd* for i386 Ubuntu is
available at http://www.physics.princeton.edu/pulsar/K1JT/kvasd .
This decoder is not open-source, is not included in the wsjtx package,
and is not required for JT65 decoding.

== OPTIONS
*-r, --rig-name*[=RIGNAME]::

Enable multiple instances of the wsjtx(1) application to run
concurrently.  Each RIGNAME must be unique. One instance may use no
RIGNAME. If this option is not supplied then only one instance of
wsjtx(1) may be run at any time.

*-v, --version*:: Display the application version.

*-h,--help*:: Display usage information.

*--test-mode*::

When this option is provided all writable files will be placed in a
special test location (~/.qttest).  This option is only for
application testing and is not designed for normal operations.  **Use
with caution**.

== FILES

Most of the following files are in a directory path containing the
directory name *WSJT-X[ - RIGNAME]* which indicates the value of the
command line option *--rig-name=RIGNAME* to indicate multiple instances of
*wsjtx* running concurrently. All writable files listed below are
therefore unique to each concurrent instance of *wsjtx*. If the
*--rig-name* command line option is not supplied or the *RIGNAME* argument
is not supplied then the directory paths below will have the directory
*WSJT-X*.

~/.config/WSJT-X[ - RIGNAME].ini::

This file stores the application
configuration settings.

~/.local/share/WSJT-X[ - RIGNAME]/ALL.txt::

*ALL.txt* contains a record of transmitted and received messages and
other activity such as frequency or band changes.

~/.local/share/WSJT-X[ - RIGNAME]/save/::

Is the default location for saved .WAV files recorded by the
application.  The .WAV file save location may be changed in the
applications settings dialog.

~/.local/share/WSJT-X[ - RIGNAME]/save/samples/::

Sample .WAV files supplied with the application are found in this
directory, they may be played back in the application and are referred
to in the user guide tutorial sections.

~/.local/share/WSJT-X[ -RIGNAME]/timer.out::

This is a diagnostic file that records decode performance profiling
information.

~/.local/share/WSJT-X[ - RIGNAME]/cty.dat::

This file is not required as a version of it is embedded in the
application, but if you wish an updated version can be placed here.
If present that version will be used in preference to the embedded
version.

~/.local/share/WSJT-X[ - RIGNAME]/wsjtx.log::

This is a plain text CSV record of logged QSOs.

~/.local/share/WSJT-X[ - RIGNAME]/wsjtx_log.adi::

This is a record of QSOs logged in the ADIF format which is suitable
for import into many Ham Radio logging programs.
