[Dxspider-support] Self-spotting and de-duplication

[Björn Ekelund]

A cluster node without skimmer spots is of very little value.
The reverse beacon network produces about 12 million spots on a
big contest weekend. This is consolidated and de-duped into perhaps half a
million.
With this in mind, what makes a few thousand self spots a problem?

The days of watching the telnet feed scroll by are long gone.
Today computers turn the spot flow into bandmap items and lists of wanted
stations.
The cluster connection is just a data feed. Not a user interface.
