[aprssig] Digi "Location-Based" Callsigns and Objects

[Robert Bruninga]

THE APRS protocol reatains the callsign of the originating station for
objects.  Maybe the Radio LISTS in the APRS radio do not capture it, but
the protocol says the client is supposed to.

So, no, you don't need to also put the callsign in the object names.

Being objects you don't have to do anything differently than you are doing
now. The originating station of course has to identify as usual, so if you
are using a tactical callsign common practice is to put your legal
callsign in the comment of the station's own beacons. As long as one of
these is sent every 10 minutes, the station is legally identified for all
packets being transmitted whether they are digipeated positions from other
stations or objects sourced from itself.

The source callsign of an object should be the actual on-air callsign of
the originating station in most cases. In your situation why would you
feel the objects need to be sourced from your callsign while being
originated from the digipeater?
