DX Monitor is a Windows program which monitors the DX announcements available on the internet at DX Summit, HB9DRV and connections to one or more local and international DX Cluster Telnet Servers. Collected DX spots can be plotted, sorted and tabulated in many ways.

Most of the spots shown below are actual reception reports, but some "comment" spots may have slipped through.
