Question
Which of the following transmissions is permitted for all amateur stations?
Answer Options
- A) Unidentified transmissions of less than 10 seconds duration for test purposes only
- B) Automatic retransmission of other amateur signals by any amateur station
- C) Occasional retransmission of weather and propagation forecast information from US government stations
- D) Encrypted messages, if not intended to facilitate a criminal act
Correct Answer: C
Explanation
FCC Rule \S 97.113(\text{c}) prohibits most forms of one-way communications and transmissions on behalf of third parties. However, one specific exception is made for transmissions of information from United States government stations for the purpose of weather and propagation forecasts.
This exception is allowed as a public service and is not seen as violating the non-commercial nature of the amateur service. Other transmissions, such as unidentified transmissions, automatic retransmission of other amateur signals, or encrypted messages (if not for space telecommand), are generally prohibited to preserve the non-commercial and open nature of the amateur airwaves.
