Free GROL Basic Radio Law and Operating Questions and Answers 1 — Questions and Answers
Question 1: What equipment is programmed to initiate the transmission of distress alerts and calls to individual stations?
- NAVTEX
- GPS
- DSC controller (Correct answer)
- Scanning Watch Receiver
Correct answer: DSC controller
Explanation: <br> A DSC (Digital Selective Calling) controller is programmed to initiate the transmission of distress alerts and calls to individual stations. It is a key component in maritime communication, allowing ships to send pre-formatted distress signals and establish direct contact with specific stations efficiently.
Question 2: Which of the following persons are ineligible to be issued a commercial radio operator license?
- Individuals who are unable to send and receive correctly by telephone spoken messages in English. (Correct answer)
- Handicapped persons with uncorrected disabilities that affect their ability to perform all duties required of commercial radio operators.
- Foreign maritime radio operators unless they are certified by the International Maritime Organization (IMO).
- U.S. Military radio operators who are still on active duty.
Correct answer: Individuals who are unable to send and receive correctly by telephone spoken messages in English.
Explanation: <br> To be eligible for a commercial radio operator license, individuals must be able to communicate effectively in English, as it is the international standard language for radio communications. This ensures clear and accurate communication in all operating situations.
Question 3: When a watch is required on 2182 kHz, at how many minutes past the hour must a 3-minute silent period be observed?
- 00, 30 (Correct answer)
- 15, 45
- 10, 40
- 05, 35
Correct answer: 00, 30
Explanation: <br> On 2182 kHz, a 3-minute silent period must be observed starting at 00 and 30 minutes past the hour. These silent periods are intended to ensure that distress calls can be heard without interference from routine traffic.
Question 4: Who is responsible for the proper maintenance of station logs?
- The station licensee.
- The commercially licensed radio operator in charge of the station.
- The ship's master and the station licensee.
- The station licensee and the radio operator are in charge of the station. (Correct answer)
Correct answer: The station licensee and the radio operator are in charge of the station.
Explanation: <br> Both the station licensee and the radio operator in charge of the station share responsibility for maintaining proper station logs. This ensures that accurate records of communication activities are kept, which is essential for regulatory compliance and operational accountability.
Question 5: Where should the GMDSS radio log be kept on board the ship?
- Captain's office
- Sea cabin
- At the GMDSS operating position (Correct answer)
- Anywhere on board the vessel
Correct answer: At the GMDSS operating position
Explanation: <br> The GMDSS (Global Maritime Distress and Safety System) radio log should be kept at the GMDSS operating position. This ensures that it is readily accessible for recording all relevant communications and for inspection by authorities when necessary.
Question 6: When may the operator of a ship radio station allow an unlicensed person to speak over the transmitter?
- At no time. Only commercially licensed radio operators may modulate the transmitting apparatus.
- When the station power does not exceed 200 watts of peak envelope power.
- When under the supervision of the licensed operator. (Correct answer)
- During the hours that the radio officer is normally off duty.
Correct answer: When under the supervision of the licensed operator.
Explanation: <br> An unlicensed person may speak over the transmitter if they are under the supervision of a licensed radio operator. This ensures that the transmission adheres to regulations and that the licensed operator can take responsibility for the communication.
Question 7: What is a bridge-to-bridge station?
- An internal communications system linking the wheelhouse with the ship's primary radio operating position and other integral ship control points.
- An inland waterways and coastal radio station serving ship stations operating within the United States.
- A portable ship station is necessary to eliminate frequent applications to operate a ship station on board different vessels.
- A VHF radio station located on a ship's navigational bridge or main control station that is used only for navigational communications. (Correct answer)
Correct answer: A VHF radio station located on a ship's navigational bridge or main control station that is used only for navigational communications.
Explanation: <br> A bridge-to-bridge station is a VHF radio station located on a ship's navigational bridge or main control station. It is specifically used for navigational communications to ensure the safety and coordination of vessel movements.
Question 8: What is the priority of communications?
- Safety, Distress, Urgency, and radio direction-finding
- Distress, Urgency, and Safety (Correct answer)
- Distress, Safety, radio direction-finding, search and rescue
- Radio direction-finding, Distress, and Safety
Correct answer: Distress, Urgency, and Safety
Explanation: <br> The priority of communications follows this order: Distress, Urgency, and Safety. Distress communications are given the highest priority as they involve situations where there is immediate danger to life or property. Urgency communications follow, concerning situations that are not immediately life-threatening but require prompt attention. Safety communications pertaining to the dissemination of important safety information.
Question 9: What should a station operator do before making a transmission?
- Except for the transmission of distress calls, determine that the frequency is not in use by monitoring the frequency before transmitting. (Correct answer)
- Transmit a general notification that the operator wishes to utilize the channel.
- Check transmitting equipment to be certain it is properly calibrated.
- Ask if the frequency is in use.
Correct answer: Except for the transmission of distress calls, determine that the frequency is not in use by monitoring the frequency before transmitting.
Explanation: <br> Before making a transmission, the station operator should determine that the frequency is not in use by monitoring it. This helps to avoid interfering with other communications that might be taking place on the same frequency, ensuring proper use and management of the radio spectrum.
Question 10: What is the order of priority of radiotelephone communications in the maritime services?
- Alarm and health and welfare communications.
- Navigation hazards, meteorological warnings, priority traffic.
- Distress calls and signals, followed by communications preceded by Urgency and Safety signals and all other communications. (Correct answer)
- Government precedence, messages concerning the safety of life and protection of property, and traffic concerning grave and imminent danger.
Correct answer: Distress calls and signals, followed by communications preceded by Urgency and Safety signals and all other communications.
Explanation: <br> In maritime radiotelephone communications, the order of priority is distress calls and signals, followed by communications preceded by Urgency and Safety signals, and then all other communications. This prioritization ensures that the most critical and time-sensitive communications receive immediate attention.
Question 11: What is a typical Urgency transmission?
- A request for medical assistance that does not rise to the level of Distress or a critical weather transmission higher than Safety. (Correct answer)
- A radio Distress transmission affecting the security of humans or property.
- Health and welfare traffic which impacts the protection of on-board personnel.
- A communications alert that important personal messages must be transmitted.
Correct answer: A request for medical assistance that does not rise to the level of Distress or a critical weather transmission higher than Safety.
Explanation: <br> Urgency transmissions are used to convey messages about situations that require urgent attention but do not pose an immediate threat to life or property. Requests for medical assistance or critical weather updates that are higher than safety concerns fall into this category.
