Was it an exciting event. AVRS, however, is just part of the overall Ham Radio Initiative for Universal Contact by-callsign Follow other links there. APRS: Automatic Packet Reporting System. APRS Paths And Digipeating 101. This discussion starts by describing the traditional APRS path conventions now considered obsolete.
This makes the reasons behind the "New Paradigm" shift to exclusively WideN-n type paths (that do away with RELAY and plain WIDE), easier to understand. The primary reason for the shift is that stand-alone digipeaters based on Kantronics KPC3+ TNCs effectively suppress duplicate transmissions based on N-n type paths but DON'T duplicate-filter on WIDE or RELAY. The original conventions were established over a decade ago. Today, there is so much traffic on APRS that channel congestion generated by needless duplicate packets generated by stupid digipeaters is a major problem.
