FREE GROL Basic Radio Law and Operating Questions and Answers
What should a station operator do before making a transmission?
Explanation:
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.
Who is responsible for the proper maintenance of station logs?
Explanation:
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.
When may the operator of a ship radio station allow an unlicensed person to speak over the transmitter?
Explanation:
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.
Which of the following persons are ineligible to be issued a commercial radio operator license?
Explanation:
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.
What equipment is programmed to initiate the transmission of distress alerts and calls to individual stations?
Explanation:
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.
What is a typical Urgency transmission?
Explanation:
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.
What is the priority of communications?
Explanation:
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.
What is a bridge-to-bridge station?
Explanation:
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.
What is the order of priority of radiotelephone communications in the maritime services?
Explanation:
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.
When a watch is required on 2182 kHz, at how many minutes past the hour must a 3-minute silent period be observed?
Explanation:
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.
Where should the GMDSS radio log be kept on board the ship?
Explanation:
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.
