Question
Under what conditions is an amateur station authorized to transmit music using a phone emission?
Answer Options
- A) When incidental to an authorized retransmission of manned spacecraft communications
- B) When the music produces no spurious emissions
- C) When transmissions are limited to less than three minutes per hour
- D) When the music is transmitted above 1280 MHz
Correct Answer: A
Explanation
The amateur radio service is generally prohibited from transmitting music because music transmission is considered a form of broadcasting (T1D02), which amateurs are not permitted to do. However, there is a single, very specific exception.
Music may be transmitted when it is incidental to an authorized retransmission of manned spacecraft communications (such as communication from the International Space Station). In this scenario, the purpose is to relay the conversation, and the music is simply background that cannot be reasonably filtered out.
