Introduction
============
Overview
--------
`PyQSO <http://christianjacobs.uk/pyqso>`_ is a logging tool for amateur radio operators. It provides a
simple graphical interface through which users can manage information
about the contacts/QSOs they make with other operators on the air. All
information is stored in a light-weight SQL database. Other key features
include:
- Customisable interface (e.g. only show callsign and frequency information).
- Import logs in `ADIF <http://www.adif.org/>`_ format, and export logs in ADIF or `Cabrillo <http://wwrof.org/cabrillo/>`_ format.
- Perform callsign lookups and auto-fill data fields using the `qrz.com <http://www.qrz.com/>`_ and `hamqth.com <http://www.hamqth.com/>`_ online databases.
- Sort the logs by individual fields.
- Print a hard-copy of logs, or print to PDF.
- Connect to Telnet-based DX clusters.
- Progress tracker for the `DXCC <http://www.arrl.org/dxcc/>`_ award.
- World map with grey line.
- Filter QSOs based on callsign (e.g. only display contacts with callsigns beginning with "M6").
- Remove duplicate QSOs.
- Basic support for the `Hamlib <http://hamlib.sourceforge.net/>`_ library.
The source code for PyQSO, written in `Python <https://www.python.org/>`_ (version 3.x), is available for download from the `GitHub repository <https://github.com/ctjacobs/pyqso>`_.
Data storage model
------------------
Many amateur radio operators choose to store all the contacts they ever
make in a single *logbook*, whereas others keep a separate logbook for
each year, for example. Each logbook may be divided up to form multiple
distinct *logs*, perhaps one for casual repeater contacts, another for satellite contacts, and another
for DX'ing. Finally, each log can contain multiple *records*. PyQSO is
based around this three-tier model for data storage, going from logbooks
at the top to individual records at the bottom.
Rather than storing each log in a separate file, a single database can
hold several logs together; in PyQSO, a database is therefore analogous
to a logbook. Within a database the user can create multiple tables
which are analogous to the logs. Within each table the user can
create/modify/delete records which are analogous to the records in each
log.
Licensing
---------
PyQSO is free software, released under the `GNU General Public License <http://www.gnu.org/licenses/gpl-3.0.en.html>`_. Please see the file called ``COPYING`` for more information. A copyright year range of the form YYYY-ZZZZ specifies every single year from YYYY to ZZZZ inclusive (for example, 2012-2017 means 2012, 2013, 2014, 2015, 2016, 2017).

Structure of this documentation
-------------------------------
The structure of this documentation is as follows. The section on `Getting Started <getting_started.html>`_ provides information on the PyQSO installation process through to creating a new logbook (or opening an existing one). The `Log Management <log_management.html>`_ section explains how to create a log in the logbook, as well as the basic operations that users can perform with existing logs, such as printing, importing/exporting logs, and sorting. The `Record Management <record_management.html>`_ section deals with the bottom layer of the three-tier model - the creation, deletion, and modification of QSO records in a log. The `Toolbox <toolbox.html>`_ section introduces the PyQSO toolbox which contains three tools that are useful to amateur radio operators: a DX cluster, a world map, and an awards progress tracker. Finally, the `Preferences <preferences.html>`_ section explains how users can set up Hamlib support and show/hide various fields in a log, along with several other user preferences that can be set via the Preferences dialog window. A `keyboard shortcuts list <shortcuts.html>`_ is also available for reference.
