I've wondered about the spelling of some station names, and sometimes I search to see if they might have gotten the name from somewhere else, like a song or book title and use that spelling in my notes.
I have a suggestion, Zeke and others could craft a small graphic with their station's logo, then encode it as a SSTV image and played after their show was over.
Now if they want to be a mystery station for the art's sake, that's fine too.
