# Toolbox

The toolbox is hidden by default. To show it, click `Toolbox` in the `View` menu.

## DX cluster

A DX cluster is essentially a server through which amateur radio operators can report and receive updates about QSOs that are in progress across the bands. PyQSO is able to connect to a DX cluster that operates using the Telnet protocol to provide a text-based alert service. As a result of the many different Telnet-based software products that DX clusters run, PyQSO currently outputs the raw data received from the DX cluster rather than trying to parse it in some way.

Click on the `Connect to Telnet Server` button and enter the DX server details in the dialog that appears. If no port is specified, PyQSO will use the default value of 23. A username and password may also need to be supplied. Once connected, the server output will appear in the DX cluster frame (see figure:dx_cluster). A command can also be sent to the server by typing it into the entry box and clicking the adjacent `Send Command` button.

## Grey line

The grey line tool (see figure:grey_line) can be used to check which parts of the world are in darkness. The position of the grey line is automatically updated every 30 minutes.

## Awards

The awards progress tracker (see figure:awards) updates its data each time a record is added, deleted, or modified. Currently only the DXCC award is supported (visit the ARRL DXCC website for more information).
