[aprssig] Gating Objects from Internet to RF

I would much prefer you use your own callsign as the originating  
station for the packets, rather than sending a packet that appears to  
come from another ham. There is nothing illegal in the way you are  
doing it because you are send on the internet, but it might make some  
of those hams uncomfortable to be listed as originating station for  
packets they never heard of. I care because when a ham Googles their  
call and finds "bootleg" packets appearing on findU I'm the guy that  
gets their angry emails. That is why I hate the DX cluster to APRS  
gateways, they generate a lot of extra work for me.
