+
+ The DXSpider DX cluster system is written in <a
+ href="http://www.perl.com">perl 5.004</a> running under <a
+ href="http://www.linuxhq.com">Linux</a> as an exercise in
+ self-training for both protocol research and teaching myself <a

+ <h4>What is a DX Cluster?</h4>
+
+ A DX Cluster is a means for Amateur (Ham) Radio operators to tell each
+ other, in realtime, about DX stations (other interesting or rare
+ Amateur Radio stations all over the world).
+
+ <p>To quote what is probably the most comprenhsive source of DX Cluster related
+ information, the <a href="http://www.cestro.com/pcluster/">DX PacketCluster WebNet</a>,
+ a Cluster is:-
+
+ <p><em>One station is set up with PacketCluster and is linked to one or
+ more other stations who have installed the software. These nodes
+ when connected are called a cluster. Clusters are connected to
+ clusters, expanding the network. Individual users connect to the
+ nodes on a frequency different from what the node stations are
+ linked on. Users are capable of announcing DX spots and related
+ announcements, send personal talk messages, send and receive
+ mail messages, search and retrive archived data, and access data
+ from information databases among its many features.</em>
+
+ <p>It's a rather specialised (and not as robust) form of IRC really.
+
+ <p>The original package runs under DOS and was created by Dick Newell AK1A
+ but is no longer under active development. Most replacements also run under
+ DOS and/or are closed source. I wanted something in open source (so I don't
+ have to do <em>all</em> the work) and for Linux.
+
+ <p>This document will contain all the instructions for its
+ installation and use - eventually...
