Which statement is true about survival craft portable VHF equipment?

• A. It operates simplex on channel 13.
• B. It operates simplex on channel 70 and at least one other channel.
• C. It is not designed for survival craft.
• D. It does not require testing or maintenance.

Answer: (A)

The essential point is how survival craft portable VHF radios are used in emergencies: they are designed for simple, reliable voice communication on a single safety channel. For survival craft, this radio operates in simplex mode on a dedicated channel, which in this context is channel 13. Simplex means you transmit and listen on the same frequency, without using any duplex arrangement or multiple channels. This keeps operation straightforward under stress and prevents confusion during rescue or coordination with nearby vessels. This is why the statement about operating on channel 13 in simplex is the correct description. It isn’t intended to rely on channel 70 (which is tied to DSC functions) or to require multiple channels for basic survival craft use. It also reflects that this equipment is designed specifically for survival craft and must be tested and maintained regularly; claims that it isn’t designed for survival craft or that it doesn’t require maintenance are inaccurate.
