Automatic Packet Reporting System
APRS is now in its 21st year!
APRS is digital communications information channel for Ham radio. As a single national channel (see map at right), it gives the mobile ham a place to monitor for 10 to 30 minutes in any area, at any time to capture what is happening in ham radio in the surrounding area. Announcements, Bulletins, Messages, Alerts, Weather, and of course a map of all this activity including objects, frequencies, satellites, nets, meetings, Hamfests, etc.
The APRS network has grown to most countries with strong Amateur Radio populations.
