One of our members, Keith, G6NHU has been running a DX Cluster since 2016. It's kept up to date with the latest version of the DX-Spider software, always has the latest country file, usdb file and satellite kep elements.
It has feeds from all continents and is nice and quick. It also takes a full feed from the Reverse Beacon Network/Skimmer.
