Which of the following statements about transmitting distress messages by radiotelephone is INCORRECT?
AI Explanation
The correct answer is C. It is incorrect that it is advisable to follow a distress message on 2182 kHz by two dashes of 10 to 15 seconds duration.
The reasoning is that the proper procedure for transmitting a distress message by radiotelephone is to first transmit the distress call on 2182 kHz. If no response is received, the distress message should then be repeated on any available frequency, not followed by two dashes. The use of the two dashes is not a standard part of the distress call protocol.
The other answer choices are correct - A, B, and D all accurately describe aspects of transmitting distress messages by radiotelephone, such as using any available frequency if no response is received on the distress frequency, and using channel 16 (156.8 MHz) for distress messages.
