The cluster panel allows you to display spots from the global DX Cluster network. The cluster is connected to other clusters (nodes) across the internet.

This allows you to be informed about any DX stations that are on-air that you may want to work.

Because the DX cluster is a global spotting network, you will probably want to do some filtering to see the spots that are relevant only to you. It makes little sense to see spots on HF between Europe and North America during our daytime, so filtering makes a lot of sense.
