[aprssig] Gating Objects from Internet to RF (fina?l)

[Lynn W. Deffenbaugh (Mr)]

The only mod I'd make is that the source call be the station's call.  We 
are beaconing positions here, but OBJECTs.  I'll be suppressing any 
object ID that I've seen on APRS-IS in the recent past (2 weeks 
currently) not created by my script.  There will be no collisions nor 
co-opting of other stations by the originating call, only objects that 
appear to be owned by that station (the information is certainly owned 
by that station) that were injected by someone else on their behalf.

I have not yet seen an issue with sourcing the packet from the station's 
callsign.
