The correct answer is "w nocy" because during the night, the atmospheric conditions are typically more stable, which allows for longer range transmission of NAVTEX signals. Additionally, there is less interference from other radio signals during nighttime hours, further enhancing the range of the NAVTEX station. This makes it the time when the NAVTEX system has the greatest coverage.

The correct answer is "ostrzeżenia meteorologiczne" (meteorological warnings). The question asks which messages will always be received and printed/displayed by the NAVTEX system receiver. This implies that regardless of other factors, such as location or time, meteorological warnings will always be received and displayed by the NAVTEX system.

The correct answer is "tak długo, dopóki nie ustanie powód, dla którego dany komunikat jest nadawany" which means "as long as the reason for which the message is being broadcasted does not cease". This indicates that the NAVTEX stations will continue to repeat the messages until the issue or reason for the communication is resolved or no longer relevant.

In odbiorniku NAVTEX, the setting of the station is done by selecting the letter corresponding to the name of the station. This means that the user needs to choose the letter that corresponds to the desired station from the available options. This allows the user to tune in to the specific station they want to receive information from.

The correct answer states that the settings for the type of information received in the NAVTEX receiver are made by setting the letter corresponding to the type of information. This means that the user can select the type of information they want to receive by choosing the corresponding letter on the NAVTEX receiver.

In tropical regions, the range of NAVTEX stations broadcasting on 518 kHz is smaller than in moderate zones.

The frequency 490 kHz is used for transmitting messages in languages other than English (national languages) in the NAVTEX system.

The frequency 4209.5 kHz is used in the NAVTEX system to transmit messages in tropical regions. NAVTEX is a worldwide automated system for broadcasting maritime safety information, including weather forecasts, navigational warnings, and search and rescue (SAR) information. Since the question specifically mentions tropical regions, it suggests that this frequency is specifically used for transmitting messages related to maritime safety in those areas.

518 kHz jest podstawową (międzynarodową) częstotliwością transmisji w systemie NAVTEX.

In the EGC SafetyNET system, safety information can be addressed to all ships within range of reception. This means that any ship that is able to receive the information will be able to access it. This ensures that all ships in the vicinity are aware of any safety-related information that may be relevant to them.

The correct answer is "komunikat nadany przez stację „J”". This is because in the given header "ZCZC JA23", "JA" represents the station identifier. Therefore, the message was sent by station "J".

If the message is assigned the NAVTEX number 00 (e.g. JD00), all NAVTEX receivers within range of the transmitting station will print/display the message, regardless of the user's station settings.

The correct answer is 200 - 400 Mm. This means that the range of the NAVTEX system when transmitting on a frequency of 518 kHz is between 200 and 400 nautical miles.

The sequence "NNN" in the NAVTEX receiver message printout indicates that the message has been received with an error rate greater than 4%.

The correct answer is "do wszystkich statków znajdujących się w zdefiniowanym obszarze (kołowym lub prostokątnym)". The System EGC SafetyNET is used to transmit maritime safety information to all ships located within a defined area, whether it is circular or rectangular in shape. This means that all ships within the specified area will receive the safety information through the system.

MSI (Maritime Safety Information) reception using the EGC (Enhanced Group Call) SafetyNet system is only possible within the coverage area of the INMARSAT satellite system. This means that the correct answer is "wyłącznie w zasięgu satelitów systemu INMARSAT" which translates to "only within the coverage area of the INMARSAT satellite system".

The correct answer is "zapisywał i/lub drukował wszystkie odebrane informacje" because it states that the EGC receiver will save and/or print all received information. This means that even if there is no current position for a period longer than 12 hours, the receiver will still record and/or print all the information it receives.

The correct answer is ALRS vol. 3. This volume contains information about maritime safety information transmission systems.

In the event of a NAVTEX receiver failure, the messages transmitted by NAVTEX stations can be received using an NBDP receiver.

The NAVTEX receiver receives and prints/displays all messages regarding navigational warnings, meteorological information, and SAR actions from programmed stations.
