nets. The concept, which dates back to the mid 1980's, is that all relevant
information is transmitted immediately to everyone in the net and every
station captures that information for consistent and standard display to all
participants. APRS also supports global callsign-to-callsign messaging,

Internet System (APRS-IS)! APRS should enable local and global amateur radio
operator contact at anytime-anywhere and using any device. See the
