How can reception of certain NAVTEX broadcasts be prevented?

The reason the option about programming the receiver to reject certain stations and message categories is correct stems from the functionality of NAVTEX receivers. NAVTEX, or Navigational Telex, is designed to provide important maritime safety information through automated broadcasts. However, operators may only need specific information relevant to their area or operations.

By allowing the receiver to be programmed, users can filter out irrelevant broadcasts effectively. This means that they can choose to accept only the information from selected stations and ignore any broadcasts from others or specific message categories that are not pertinent to their needs. This capability is particularly useful in busy maritime environments where superfluous information could lead to information overload and distract from critical communications.

The other options outlined do not directly address the ability to control the specific reception of broadcasts. For example, stations limited to daytime operation would not be a reliable method for preventing reception; it would only affect the timing of broadcasts rather than filtering specific content. Coordinating reception with published broadcast schedules offers an organizational approach but does not provide a mechanism to control which broadcasts are received. Automatic receiver desensitization during night hours might reduce interference but does not directly prevent the reception of unwanted messages. Thus, the programming feature of receivers is the most effective way to tailor broadcasts to
