xCluster is a visual display of dx cluster activity built for the iPad. DX spots are received via telnet or web services and displayed in a tabular form and plotted on a map of the world. You can filter the spots by call sign or band. Spots are created using the latitude and longitude of the dx station and spotter. The program has an internal call parsing component to determine the country for each call but can use QRZ.com for more accurate location data. Lookup priority is QRZ.com with the the call parser as a backup. DX spots can be displayed on a map or in a tabular form. Alerts for specific stations, bands or countries may be set and will be highlighted in the list and on the map. A number of major telnet clusters are built in along with DXSummit and PSK Reporter. PSK Reporter will display other stations that can hear your signal. You must be running WSJT-X or FLDIGI and have it configured correctly to work.
