🔍 Key Concepts

• Selective FEC (SFEC) versus FEC in general • The role of a transmitter in phasing and error correction • Difference between individual call and multiple/group call in digital selective calling (DSC) / telex

💭 Think About

• Ask yourself: in SFEC, is the receiving station required to transmit anything back to the sending station for the system to work? • Which options describe multiple stations versus an individual station, and which better matches the idea of selective FEC? • Look for the choice that best matches a system where the sender can direct error-protected traffic to one station (or a subset) without requiring them to break radio silence.

✅ Before You Answer

• Verify whether phasing requires the receiver to transmit back to the sender. • Check which options mention radio silence and whether SFEC is specifically designed for that situation. • Confirm if SFEC is normally used for one addressed station or for many stations without a group call.
