The communication statistics that we show here may differ from similar communication statistics on other websites, the reason is that we are not collecting packets from the same APRS-IS servers. Each APRS-IS server performes duplicate filtering, and which packet that is considered to be a duplicate may differ depending on which APRS-IS server you receive your data from.

To include all duplicate packets in our statistics we would need a duplicate feed from all APRS-IS servers in the world (that would be hundreds of servers). The APRS Direct website collects it's packets from our own APRS-IS server, which is connected to a APRS-IS core server.

Please note that if distance is very long it may be incorrect (not all digis add themselves correctly to the path).
