Question
Under which of the following circumstances are one-way transmissions by an amateur station prohibited?
Answer Options
- A) In all circumstances
- B) Broadcasting
- C) International Morse Code Practice
- D) Telecommand or transmissions of telemetry
Correct Answer: B
Explanation
The FCC rules strictly prohibit amateur stations from engaging in broadcasting. Broadcasting is defined as transmissions intended for reception by the general public, where no response or conversation is expected (one-way). Amateur radio is fundamentally a two-way communication service.
While general one-way transmissions are prohibited, there are explicit exceptions where one-way communication is permitted. These exceptions include beacon transmissions (T1A06), international Morse code practice, and transmissions of control commands (telecommand) to model craft or satellites. However, transmissions aimed at the public remain prohibited.
