DX-Atlas  AR-Cluster Sysop Manual

AR-Cluster supports an interface into DX-Atlas by VE3NEA.  DX-Atlas is an electronic World Atlas designed for radio amateurs.  The DX-Atlas configuration is done using the MAP option on the AR-Cluster main menu.  Settings are restored when the application is restarted.  The following options are available:


DX-Atlas Enabled – Enable AR-Cluster support for DX-Atlas.  Keep this option off if you are not using DX-Atlas as geo-referencing DX spots to be sent to DX-Atlas requires extra CPU resources.

AutoStart – Allows the automatic starting of DX-Atlas when launching AR-Cluster

Show/Configuration – Plot the configuration of the cluster to DX-Atlas

Show/Nodes – Plot the configuration of the cluster nodes to DX-Atlas

Show/Users – Plot the configuration of the cluster users to DX-Atlas

Center Home – Centers the DX-Atlas map on your node coordinates

Clear – Clears the DX-Atlas points

Center DX Cty – Centers the map on each DX spot as they come into the node.

Center Spotter – Centers the map on each DX spotter’s QTH.

Plot DX Spots – Plot a line from the spotter to the DX.

Cfg Filters – Controls the filtering of DX spots processed and sent to DX-Atlas.


The plotting of DX-Atlas points uses the AR-Technology Callsign database to geo-reference the DX and the DX spotter’s position.   The enhanced capabilities include plotting of the spot to the street level.  DX spots on the bottom of each band (1800, 3500, 7000, 14000, 21000, 28000, and 50000) are dropped as they are generally used for announcements and do not generally reflect actual propagation.


A special Over-Zoom feature is built into DX-Atlas to allow AR-Cluster sysops to plot their RF connected users in a tight radius around their node.  This feature is configured in the DX-Atlas.ini file.  To enable add the following parameter lines:


  OverZoom = 12
