Which statement is NOT true regarding the requirements of survival craft portable two-way VHF radiotelephone equipment?
Official USCG Answer & Rule Citation
Correct Answer: Option A — Operates simplex on Ch-70 and at least one other channel.
Survival craft VHF radios are designed for voice communication, not DSC. Channel 70 is exclusively reserved for DSC alerting and is not used for voice traffic. Portable units must be simplex, watertight, and have fixed antennas to meet IMO performance standards for emergency equipment.
