Under what conditions is an amateur station authorized to transmit music using a phone emission?

Answer: A. When incidental to an authorized retransmission of manned spacecraft communications

Music is allowed only when it is incidental to an authorized retransmission of manned spacecraft communications, under FCC rule 97.113. For example, if astronauts play music in the background, a retransmission of that audio is OK.

Tip: Music on ham radio: only in the background of spacecraft audio.

FCC rule reference: Part 97.113(a)(4), 97.113(c)
