Are you sure about that?  Surely if I broadcast a binary via radio
waves I'm required to also broadcast the source.

Well, I still don't think you're correct (see the question about "the
guy in the corner recording the performance on his video camera").

And I certainly meant to include radio broadcasts, including digital
radio broadcasts (XM satellite, HD radio).

I'm not, because I think it's absolutely crystal clear that *if*
public performance and public display *of the work* is allowed, then
it must follow the rules for conveyed copies.

Publicly performing or publicly displaying *the output produced by
running the program*, on the other hand, is unrestricted.
