When may an amateur radio operator transmit unidentified communications?
- A Only if it does not interfere with others
- B Only for two-way or third-party communications
- C Only to control a model craft
- D Only for brief tests not meant as messages
Correct answer: C — Only to control a model craft. From the official ISED question bank, verified word for word.
Why
You may transmit without identifying your station only when sending control signals to a model craft, such as a radio-controlled airplane or boat, because these short bursts are considered commands rather than conversations. The full explanation — and one for every question — is in Pro.
