Which modes could be selected to receive vessel traffic lists from high seas coast radio stations?

To understand why selecting SSB (Single Sideband) and FEC (Forward Error Correction) is the correct choice for receiving vessel traffic lists from high seas coast radio stations, it's important to consider the communication environments and protocols used in maritime operations.

SSB is a commonly used mode in maritime communication primarily because of its long-range capabilities. It allows for efficient transmission over long distances, which is critical when it comes to high seas communication where vessels may be far from shore. It utilizes less power while maintaining a clear signal over large distances, which is essential for vessels operating in remote areas.

FEC is a method added to communication protocols to improve transmission reliability. It allows the receiving station to detect and correct errors that may occur during the transmission of data. This is extremely important in maritime communication, particularly when dealing with important information such as vessel traffic lists. The again given the unpredictable conditions at sea, the ability to receive clear and correct data becomes crucial.

While other combinations mention modes like AM or VHF-FM, these are generally more suitable for short-range communications. AM is more prone to interference, and VHF-FM, while useful for coastal communications and shorter distances, does not have the long-range capabilities of SSB. Therefore, for high
