Welcome to the SDR-Radio DX Cluster based on an original idea by the members of the OH9W / OH2AQ Radio Club.

Just click on an entry on the left: DX spots are displayed immediately and are refreshed every 30 seconds (Top 50) or every 180 seconds (Top 250). For the fastest updates please select an entry from the Top 50 list.

The data is taken from the Amateur Radio DX cluster using custom Perl scripts together with DXSpider by Dirk Koopman, G1TLH. More technical information is available here.

The DX Cluster is hosted on the corporate servers of Sysgem AG.
