[CQ-Contest] Special RBN Configuration for CQWPX CW Contest

We've been working hard to improve the reliability and throughput of the 
RBN, because the trend in traffic points nowhere but up.  Traditional 
cluster node software, particularly when required to do extensive 
user-defined filtering or database queries, tends to buckle under the load

This weekend, for the WPX CW contest, we will be running a special 
configuration of  3 RBN servers, to test some new hardware and software 
under heavy volume. We're hopeful the result will be 100% reliability 
and data integrity, and we'll be carefully monitoring performance all 

Individual RBN contributors will notice no difference, and will not need 
to change a thing.  However, we are encouraging all RBN contributors to 
upgrade to Aggregator 3.0 when they have a few minutes, because it is 
significantly faster than 2.4 or 2.61.

So here's how things will look:

telnet.reversebeacon.net, port 7000 will continue to run AR Cluster 
Version 6 software.

arcluster.reversebeacon.net, port 7000 will run a Windows relay server 
written by Lee, VE7CC. After the contest we will probably be renaming 
this server to Relay1, but for now we didn't want to upset people's 

Relay2.reversebeacon.net, port 7000 will run a Linux relay server 
written by Felipe PY1NB and Dave, KM3T.

PLEASE NOTE: Both relay nodes are lean servers with *no* user filtering, 
databases or other things that contribute to CPU or communications 
loading. If you ask them to filter spots that you receive, they will 
ignore you!

We're trying hard to move to a wholesale/retail model, encouraging 
end-users of RBN data to connect to one or more of the many cluster 
nodes thatare set up to serve you, with filtering and other 
capabilities.  Extensive Telnet listings are available at 
http://www.dxcluster.info - look for entries that have "(+CW Skimmer)" 
in the first column.
