About RM6AA DX Cluster

RM6AA DX Cluster is a multi-source DX spot aggregation server. The cluster receives DX spots from multiple upstream sources, processes them and distributes them to connected amateur radio operators.

The server uses the standard DX Cluster Telnet protocol and can be connected directly from compatible amateur radio logging and contest software.

Individual DX spot filters can be configured for each user. Filter settings are stored by login callsign and restored automatically when the user reconnects.

    This is the default.

    Same as SET/DUP 1.


SET/NODUP
    Allow D:1 spots only.

    Return to all D values.

Filter Behavior

Your filter settings are saved by login callsign and restored automatically on your next connection.

Filters apply both to live DX spots and to the SH/DX command.

An empty filter means ALL.
