Which of the following statements concerning SITOR communications is true?

The statement that two-way communication with the coast radio station using FEC is not necessary to be able to receive the broadcasts is accurate. SITOR (Simple Inverse Telex Over Radio) is designed for the transmission of text messages, specifically in maritime communications, and it operates through a form of automated radio teleprinter communication. While Forward Error Correction (FEC) is typically employed to increase the reliability of the received messages by correcting errors that may occur during transmission, SITOR can still receive broadcasts even if there isn’t a two-way communication link established.

This flexibility is important in maritime contexts since vessels may not always maintain constant two-way communication with coast stations. It allows ships to receive important navigational and safety information without needing to send a message back, which may not always be feasible due to equipment limitations or operational circumstances. Thus, the accuracy of transmissions ensured by FEC aids in improving message integrity but isn't a prerequisite for receiving broadcasts.
