xCluster vs APRS Tracker Digi iGate

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.

Stay visible. Stay connected. This app is a tool for radio amateurs, civil defense volunteer teams, and operators using the APRS protocol in field activities. The app allows you to transmit your position to the APRS-IS network via the internet and also operate directly via radio using AX.25 packets with 1200 AFSK modulation. It can be used for individual tracking, local communication, and supporting the infrastructure of an APRS network. Whether in expeditions, amateur radio events, travel in remote areas, or search and humanitarian aid operations, APRS Tracker provides features to track stations, share points of interest, and expand APRS coverage. KEY FEATURES APRS-IS Tracking Send your GPS coordinates to APRS-IS servers via the device's internet connection. Positions can be tracked on compatible public services, such as aprs.fi. AX.25 / 1200 AFSK RF Mode Transmit and receive APRS packets through the device's audio input and output. With a radio and a compatible audio interface, you can operate via RF even without internet access. APRS Digipeater Use the app as a digital repeater to extend the range of stations in the area. The Digipeater processes paths compatible with New-N rules and includes controls against loops, invalid paths, and duplicate packets. iGate Mode Forward valid packets received via radio to APRS-IS, allowing local stations to be viewed on the worldwide APRS network. Optional internet-to-RF forwarding features packet type selection, radius definition, security filters, and frequency limits. APRS Objects Register important points, such as shelters, support bases, aid posts, repeaters, obstacles, risk areas, or meeting places. Each object can contain a name, coordinates, symbol, and message, with publication via internet and/or RF. Mobile or Fixed Station Use dynamic location while on the move or configure fixed coordinates to operate as a base, iGate, Digipeater, or support station. Symbols and Status Messages Choose the APRS symbol representing your station, vehicle, or activity, and add a message to inform your condition or mission. Communication Monitoring Track sent and received packets in the integrated terminal, along with the status of the APRS-IS connection and RF operation. Automatic Reconnection After temporary internet interruptions, the app attempts to re-establish the connection with the APRS-IS server. USE CASES Tracking during trips, expeditions, and outdoor activities. Monitoring of vehicles and volunteer teams in the field. Support for search, rescue, civil defense, and humanitarian aid operations. Local APRS radio operation in areas without internet. Temporary installation of an iGate or Digipeater to expand coverage. Publishing shelters, bases, risks, and support points as APRS Objects. Technical monitoring of AX.25 packets and APRS-IS communication. SIMPLE AND CONFIGURABLE Enter your amateur radio callsign, Passcode, server, and transmission preferences to begin. RF, Digipeater, and iGate features are disabled by default and only work when enabled by the user. IMPORTANT REQUIREMENTS Access to APRS-IS requires an amateur radio callsign and a valid Passcode. RF operation requires a radio and a compatible audio interface. Performance depends on equipment, audio levels, VOX/PTT configuration, and channel conditions. Continuous use of GPS, audio, and background execution may increase battery consumption.
