Again, you show a complete lack of understanding for the ways tactical
callsigns are used. They are NOT used to place static objects on the
They are used to improve communications by providing a link between
hard to remember callsigns and easy to remember words. They give an
aliased station access to the FULL RANGE of the APRS protocol, not
just the reporting of a position.
For example, imagine a marathon, with a tracker on the lead and tail
vehicle, and one on a medivan. All are under my callsign, say with
SSID's of -4,-5,and -6.
If you look at a map with K4HG-4, K4HG-5, and K4HG-6 on a map, it is
hard to remember which is which. On the other hand, if you use LEAD,
TAIL, and MEDIC, anyone can look at the map and see what is going on.
Your proposal outlaws this, as there is no way for a tracker to send
an an object with its own position! Selfish!
Now, make a real life situation with dozens of trackers and manned
APRS stations, where messages are being sent, where there are multiple
callsigns on the air, it becomes critical that tactical callsigns are
