Satellite stations that rebroadcast 100 percent of the parent station do not need to register. Only one registration needed per EAS box.

I'm just double checking since I saw a post on here where someone mentioned registering a "satellite" station. We only need to register the stations that actually broadcast programming and have an endec at that site, right? All of my satellite stations broadcast what is on the main signal, so they will all broadcast an NPT.
