Actually, APRS is more then just throwing out a position report for which the BTech Pro is doing for which only other BTech Pro users can see. Though APRS is used primarily in VHF at 144.390mhz US at 1200 baud, can be used at 9600 baud UHF, and 300 Baud HF. Position reporting, weather, telemetry, messaging, and other uses like IGATE, Digipeaters relaying others beacons and messages over airwaves and thru the internet back to airwaves world wide. So people might be getting confused about the terms and what can be done with it. APRS in Amateur radio is just another form of packet radio that is used in the spectrum area of VHF that can be used for AX.25 packet protocol. Position reporting is one thing, heck my Harris XG100P can give and receive position reports from other Harris users on P25 protocol which is called SA"situation awareness" just by keying up mic button. That is just postion reporting, not APRS. So people have to realize that there are huge differences with certain gear and should not confuse the terms.
