This software receives spots from CW Skimmer or Skimmer Server's telnet port, and send the spots to the Reverse Beacon Network.

Aggregator must be running whenever you wish to send spots to the RBN. No installation is required - just copy the aggregator file to the same folder where CW Skimmer is, and place a shortcut on an appropriate place like the desktop.

We encourage you to set your Skimmer to send all spots (DE & CQ) to the telnet port.

Aggregator will warn you if there is a newer version of the software available than the one you are currently using.

Microsoft .NET framework version 4 must be installed.
