Which of these is not a primary purpose of the MF/HF DSC controller?

• A. It provides for the electronic memory of incoming and outgoing DSC calls.
• B. It permits control of transceiver operations in response to an incoming DSC call.
• C. It provides for the formatting and transmission of outgoing DSC calls.
• D. It provides the scanning watch receiver capability on the 6 MF/HF DSC frequencies.

Answer: (D)

The primary functions of the MF/HF DSC (Digital Selective Calling) controller are to manage communication effectively and ensure reliable operation when sending and receiving distress and other maritime safety messages. The functions include managing electronic memory for incoming and outgoing communications, controlling transceiver operations based on incoming calls, and formatting transmissions for outgoing messages. The option regarding scanning watch receiver capabilities does not align with the primary functions of the DSC controller. While monitoring distress frequencies is crucial in maritime communication for safety, the specific scanning capability is typically associated with the transceiver itself, rather than the DSC controller’s primary responsibilities. Hence, this distinguishes the other three choices, which directly relate to the core functionalities of the DSC controller.
