Iss as a station ? 

I was worried about that 

Iss is not a station 

Iss is an object 

Illegal ?

I made the ISS satellite an object sourced by KJ4ERJ-15 to provide for trackability and to adhere to the established norms (as I saw them, at least) that stations were "real" and objects were "manufactured".  Yes, they may be designed to be displayed the same, but there was some resistance to making RFID-implied locations "stations" rather than "objects" as it was somehow deemed "spoofing" something that wasn't really APRS.
