Question 16Rules and Regulations Governing the Maritime Radio Service

After transmitting a false distress alert, what action is required?

  1. Wait for a rescue unit to call the station
  2. Notify the Coast Guard and cancel it Correct answer.
  3. Switch off the radio and leave the area
  4. Continue normal traffic and say nothing

Explanation

A station that transmits a false distress alert must notify the appropriate rescue coordination authority and cancel the alert. Prompt cancellation prevents unnecessary search and rescue operations.

Which spoken signal begins a distress message relayed on behalf of another station?

  1. MAYDAY RELAY Correct answer.
  2. SECURITE
  3. SEELONCE MAYDAY

Question 23Rules and Regulations Governing the Maritime Radio Service

How is a U.S. ship radiotelephone station normally identified in voice communications?

  1. By the vessel's hull number
  2. By the captain's permit number
  3. By the vessel's home port
  4. By its FCC call sign Correct answer.

Explanation

A U.S. ship radiotelephone station is normally identified by the call sign assigned by the FCC. The vessel name may also be used in accordance with the applicable procedures.

Question 24Rules and Regulations Governing the Maritime Radio Service

After sending a VHF DSC distress alert, what should the operator normally do?

  1. Send a second DSC alert on Channel 16
  2. Send a MAYDAY voice call on Channel 16 Correct answer.
  3. Turn off the radio to conserve battery power
  4. Switch to Channel 13 and wait for a reply

Explanation

After a VHF DSC distress alert, the operator should normally follow with a MAYDAY voice distress call on Channel 16. The voice call provides details and confirms the distress to stations monitoring the channel.

Explanation

A station causing harmful interference must eliminate it, which may require reducing power, changing frequency, or ceasing transmission. Operators may not simply increase power or continue causing interference.

Question 32Rules and Regulations Governing the Maritime Radio Service

What does the spoken signal SECURITE indicate?

  1. Safety Correct answer.
  2. Urgency
  3. Routine
  4. Distress

Explanation

SECURITE announces a safety message, such as a navigational warning or weather warning. It has lower priority than distress and urgency signals but higher priority than routine traffic.

Question 33Rules and Regulations Governing the Maritime Radio Service

Which spoken word begins a radiotelephone distress call?

  1. Security
  2. Mayday Correct answer.
  3. Pan Pan
  4. Roger

Explanation

The word MAYDAY, spoken three times, identifies a distress call and indicates grave and imminent danger requiring immediate assistance. The other words serve different purposes or are procedural acknowledgments.

Question 34Rules and Regulations Governing the Maritime Radio Service

On 2182 kHz radiotelephony, what are the required silence periods?

  1. Five minutes before the top of each hour
  2. Three minutes after each hour and half hour Correct answer.
  3. Continuously throughout the hour
  4. One minute following each quarter-hour mark

Which spoken signal precedes an urgent message about the safety of a vessel that is not in immediate distress?

  1. PAN PAN Correct answer.
  2. SECURITE
  3. MAYDAY
  4. ROGER

Explanation

PAN PAN announces an urgency message concerning the safety of a vessel or person but not a situation of grave and imminent danger. MAYDAY is for distress, SECURITE for safety messages, and ROGER is an acknowledgment.

Question 40Rules and Regulations Governing the Maritime Radio Service

Is an FCC ship station license required for a recreational vessel using a VHF radio only in U.S. waters, and is an operator permit needed?

  1. No, and no operator permit of any kind is needed
  2. Yes, but only when a DSC controller is installed
  3. Yes, a ship station license is required in every case
  4. No, but an operator permit is still required Correct answer.

Explanation

Recreational vessels operating domestically are generally exempt from the ship station license requirement, but the operator must still hold a Restricted Radiotelephone Operator Permit. DSC installation does not create a separate license requirement for that domestic use.

Question 41Rules and Regulations Governing the Maritime Radio Service

Which vessels are required to maintain a radio log?

  1. Only recreational vessels
  2. Only vessels over 100 gross tons
  3. Vessels subject to GMDSS rules Correct answer.
  4. All vessels carrying a VHF radio

Explanation

Radio log requirements apply to vessels subject to GMDSS rules, which must record distress, urgency, safety, and other specified communications. A VHF radio alone does not create a log requirement.

Question 42Rules and Regulations Governing the Maritime Radio Service

What should a station do upon hearing a distress call from another vessel?

  1. Continue routine traffic
  2. Ignore the call unless your own vessel is involved
  3. Acknowledge and assist if possible Correct answer.
  4. Wait for a coast station only

Explanation

A station that hears a distress call should acknowledge it if practicable and render assistance or relay the call. Routine traffic must not continue on a frequency being used for distress communications.

Question 43Rules and Regulations Governing the Maritime Radio Service

What authorization document should be kept available aboard a ship station for inspection?

  1. Vessel registration certificate
  2. Operator's passport
  3. FCC ship station license Correct answer.
  4. Insurance certificate

Explanation

The FCC ship station license authorizes the station and must be available for inspection by authorized representatives. The other documents do not authorize radio operation.

Question 44Rules and Regulations Governing the Maritime Radio Service

What is the purpose of the NAVTEX system?

  1. Broadcasting weather and navigation warnings Correct answer.
  2. Relaying distress alerts to satellites
  3. Tracking vessel positions by radar

What should a licensee do if the ship station license is lost or destroyed?

  1. Request a duplicate from the FCC Correct answer.
  2. Use another vessel's license copy
  3. Operate under a temporary call sign
  4. Cease all radio operations

Explanation

A licensee may obtain a duplicate license from the FCC to replace a lost or destroyed document. The station authorization itself is not automatically terminated by losing the paper copy.

Which ITU region includes the United States for maritime radio purposes?

  1. Region 4 (Asia)
  2. Region 3
  3. Region 1

A compulsory ship is one to which the GMDSS carriage requirements apply under international convention, generally SOLAS vessels on international voyages. The other descriptions do not define a compulsory GMDSS ship.

Question 48Rules and Regulations Governing the Maritime Radio Service

What is the primary purpose of the Automatic Identification System (AIS)?

  1. To broadcast weather forecasts
  2. To transmit distress alerts to satellites
  3. To provide encrypted voice communications
  4. To share vessel identity and position Correct answer.

Explanation

AIS automatically exchanges vessel identity, position, course, and speed information with other stations for collision avoidance and traffic monitoring. It is not a weather broadcast, secure voice, or satellite distress system.

Question 49Rules and Regulations Governing the Maritime Radio Service

What must a licensee do when a vessel's name or call sign changes?

  1. Notify the local Coast Guard station in writing
  2. Apply to the FCC to modify the license Correct answer.
  3. Paint the new name on the hull
  4. No action is required

Explanation

A change to licensing information such as the vessel name or call sign requires the licensee to request a modification of the ship station license. Painting the hull or notifying another agency does not amend the FCC authorization.

Question 50Rules and Regulations Governing the Maritime Radio Service

Which statement about emergency radio operations is correct?

  1. Distress traffic requires prior FCC approval
  2. Only licensed operators may transmit in an emergency
  3. Only coast stations may originate distress traffic
  4. Any station may use any means to obtain help Correct answer.

Explanation

In an emergency, any station may use any available means of communication to attract attention and obtain assistance, even if normal operating rules would otherwise restrict the transmission. Prior approval or licensed status is not a precondition for emergency calls.
