Incoming spots are displayed in the Path Grid as they arrive, sorted by the column or columns you’ve selected. The green squares with lines above them are all Skimmers that have recently reported to the RBN. The lines and dots are colored by band, with a dot at the distant end of each spot with either the DE or DX side near me (inside the red circle).

The screenshot below shows DxAtlas during a contest, centered at my QTH in ZL, with multiple features enabled. While ViewProp is running, you can use DxAtlas in all the ways you usually do, including things like grayline and ITU or CQ grids, alternative map projections (rectangular, globe or azimuthal), and Ham CAP. You can see details about a spot by hovering the mouse over it.

The size of the dot is based on how many spots resolve to the same lat/lon. The colors of the dots are determined by the band of the spot. It can help you with planning by providing charts showing a history of activity over the previous day, and it also lets you view and optimize antenna pointing directions. But securing the grid against attack is difficult, and many analysts say the task is becoming harder as the use of renewable energy and cloud-linked “smart” energy-efficiency technology grows.ViewProp is a tool that allows you to view and analyze propagation in real-time by plotting the geographic location of open paths in DxAtlas as determined from Skimmer and cluster spots. In February, President Obama announced a plan to help government agencies, businesses and the public prevent and respond to attacks. Although some security experts say a massive, long-term blackout is unlikely, industry and government officials are working to protect the grid and improve coordination between agencies and utilities. The electric grid - a patchwork of more than 300,000 miles of transmission lines and 9,200 generating stations - also is vulnerable to attacks by gun- or bomb-wielding terrorists or saboteurs. A Nebraska-based consortium of small municipal utilities, for example, recently detected nearly 4 million hacking attempts in one eight-week period. The United States is spending more on cybersecurity today than ever before but is experiencing a growing number of cyberattacks on the power grid and other targets.
