Last path:	KC3VPC-1>APRS via WIDE2-3,WIDE1-1,qAR,N3FYI-2 If WIDE1-1 is used in the path, it should be the first component of the path, so that a fill-in digipeater would be the first one to retransmit the packet. Path element WIDE2-3 does work - please use WIDE2-2 instead. In path element WIDEn-N, n must be greater than or equal to N.

This page shows real-time information collected from the Automatic Position Reporting System Internet network (APRS-IS). APRS is used by amateur (ham) radio operators to transmit real-time position information, weather data, telemetry and messages over the radio. A vehicle equipped with a GPS receiver, a VHF transmitter or HF transceiver and a small computer device called a tracker transmits it's location, speed and course in a small data packet, which is then received by a nearby iGate receiving site which forwards the packet on the Internet. Systems connected to the Internet can send information on the APRS-IS without a radio transmitter, or collect and display information transmitted anywhere in the world.
