I think the FCC would want to know about your coded
transmissions, which along with transmitting music are not
permitted on ham radio.
I think the coded transmission restriction is a sop to the
national security professional paranoids, but it was much more
useful in the 1920-1990 time frame than it is now, given how
easy international communication is via the Internet. The music
limitation is to protect radio hobbyists from having to compete
with wanna-be-broadcasters.
There are some exceptions to the coded transmission restriction
including control of amateur radio satellites and protocols that
support authentication without secrecy. The latter makes me
occasionally think about all those authentication only protocols
I didn't discuss during the crypto wars of the 1990s.
