TCP/IP DX-cluster client for Amateur Radio

## NAME

Xdx - TCP/IP DX-cluster client for Amateur Radio

## SYNOPSIS

**xdx** \[**-c** *cty.dat*\] \[**-h**\] \[**-V**\]

## DESCRIPTION

Xdx is a DX-cluster client for the X Window System which shows a list of DX announcements and a separate list of WWV, WCY, “To ALL” and other server messages in a single X11 window. Xdx uses the telnet protocol to connect to a DX-Cluster host via TCP/IP. While host connections are most commonly made via the Internet, any medium capable of carrying TCP/IP, such as packet radio, may be used. Host connection details are saved between sessions.

## OPTIONS

The following options are recognized by Xdx.

- **-c** *cty.dat***, --cty\_dat=***cty.dat*

  Load a desired country data file.

-

  Country data files are used to determine the DX Century Club (DXCC) entity shown in the Country column. Updated country files are available from country-files.com ⟨http://\\:www.country\\-files.com/\\:cty/\\:cty.dat⟩ Although a country file is installed as a part of Xdx, it will quickly become out of date as updates are made available frequently. Announcements of updated country files are sent to the Xdx mailing list. See the **BUGS** section below for the mailing list address.

-

  See the **ENVIRONMENT** and **FILES** sections below for other methods of loading an updated country file.

- **-h**, **--help**

  Print short Xdx usage message detailing available options and exit.

- **-V**, **--version**

  Print Xdx version and short copyright information then exit.

## ENVIRONMENT

- **XDX\_CTY**

  If $**XDX\_CTY** is set, its value is the location of the *cty.dat* file. Using the **-c** option overrides this environment variable.

## FILES

- $**HOME***/.xdx/cty.dat*

  *Xdx will load the country file found in the preferences* *directory, normally $***HOME***/.xdx*, if the **-c** option is not given or the **XDX\_CTY** environment variable is not set. This is a convenient way to keep an up-to-date or custom *cty.dat* for use just with Xdx.

## NOTES

Xdx has a new maintainer, Nate Bargmann, N0NB.

Development is currently hosted at GitHUb ⟨https://github.com/N0NB/xdx⟩
