At the March 4, 2016, meeting, Rich KE1B presented the modern tools that hams use for DX reports. Instead of relying on telephones or FM repeaters, hams now use Internet-connected computer programs to communicate automatically where and when DX signals have been received (or “spotted”).
Internet-connected logging programs update information to DX Cluster nodes automatically, making it easy to see who else is communicating from your area to other parts of the world. In addition, there are automatic “skimmers” for the digital modes. These dedicated systems decode RTTY and CW signals and upload their spottings automatically.
