Providing real-time tactical digital communications in conjunction with a map showing the locations of stations✓Correct answer
Automatically showing the number of packets transmitted via PACTOR during a specific time interval
Providing voice over internet connection between repeaters
Providing information on the number of stations signed into a repeater
Explanation
The value of APRS in the field is that position and status packets from many stations are plotted on a shared map in real time, giving everyone a live picture of where people and resources are, which is what makes it useful for public service events. The other choices describe statistics, voice linking and repeater logging, which are not APRS functions.
