Question T1D04
From subelement T1 - T1D
Under what conditions is an amateur station authorized to transmit music using a phone emission?
Why is this correct?
Music transmission is generally prohibited on amateur radio, with only one specific exception. Answer A is correct because amateur stations may transmit music only when it's incidental to retransmitting authorized manned spacecraft communications. The other options are incorrect: spurious emissions (B), time limits (C), and frequency bands (D) have no bearing on music transmission rules under Part 97.113(a)(4).
Memory tip
Remember the 'spacecraft exception' pattern — amateur radio has very few absolute prohibitions, but when exceptions exist, they're typically very specific and narrow. Look for the most restrictive, situational answer rather than general technical conditions when dealing with prohibited activities.

This exception exists because NASA and other space agencies sometimes include music in their official spacecraft transmissions for crew morale or public relations. When amateur stations are authorized to retransmit these official communications under Part 97.113(c), any incidental music becomes legally permissible. This maintains amateur radio's educational mission while supporting space communication activities that serve the public interest.
Think about it
Why do you think the FCC created such a narrow, specific exception for music transmission rather than allowing broader categories like 'emergency communications' or 'educational purposes'?
