Q

How is a NAVTEX receiver programmed to reject certain messages?

🔍 Key Concepts

• NAVTEX message categories identified by single letters A–Z • Difference between station identification codes and message category selection • What functions are normally available in the receiver’s setup/menu (selecting or deselecting types of messages)

💭 Think About

• Ask yourself: do operators usually block an entire transmitting station, or do they more often block certain types of messages from all stations? • Consider how a mariner would avoid clutter but still receive safety and distress-related messages—what setting would make the most sense? • Think about whether NAVTEX uses SELCAL codes like HF radiotelephone, or if it uses simpler IDs and category letters.

✅ Before You Answer

• Verify which NAVTEX feature allows turning specific message types on or off in the receiver menu. • Check whether NAVTEX documentation mentions SELCAL at all for routine programming—if not, be cautious of that choice. • Confirm that any correct method should align with the goal: reduce unwanted traffic without losing critical safety information.
