Question 3-88N6

NAVTEX (Navigational Telex) receivers are designed with filtering capabilities to manage the volume of information. Each NAVTEX message begins with a header that includes a "subject indicator character" (e.g., A for navigational warnings, B for meteorological warnings). Operators can program their receiver to *reject* or *suppress* the printing of specific message types they deem irrelevant, such as routine weather forecasts (E) or pilot service messages (G), while still printing critical warnings. Therefore, if the subject indicator of a message matches one the operator has programmed for rejection, that particular message content will not be printed. A is incorrect because NAVTEX broadcasts are not vessel-specific; all vessels within range receive the same messages. The receiver cannot discern if content "concerns your vessel" based on its text. C is incorrect because rejecting a *station ID* would stop *all* messages from that station, not just a particular *type* of content. D is incorrect as the primary purpose of programmable filtering is to avoid printing all messages, saving paper and user attention.
