Q

Which of the following statements concerning SITOR communications is true?
•Communication is established on the working channel and answerbacks are exchanged before FC broadcasts can be received.

•In the ARQ mode each character is transmitted twice.

•Weather broadcasts cannot be made in FEC because sending each character twice would cause the broadcast to be prohibitively long.

•Two-way communication with the coast radio station using FEC is not necessary to be able to receive the broadcasts.

A

Two-way communication with the coast radio station using FC is not necessary to be able to receive the broadcasts.
