You might also be able to identify openings that you didn’t know about before. You can use this chart to quickly see when the bands are at their most active from your QTH. One chart shows the number of spots by band vs.
Spots on the Path Grid and map are also tracked in a couple of charts. Spots age out and are removed from the Path Grid after 60 minutes, so the list always reflects recent propagation from your QTH. The arrows in the dB column show the SNR trend for all spots over the same path (same DE and DX) over the last 45 minutes. If you have an XML qrz.com subscription, ViewProp will use it to refine the lat/lon and zone details, and to find the name of the person or club associated with the call. 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. 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.
