A lot of my contest QSO's this past weekend went like this: 1. I send CQ SS 2. He sends his callsign 3. I send his callsign 4. I send exchange 5. He sends my callsign 6. He sends exchange What is the purpose of line 5? In those instances when I answered a CQ, I did not include line 5. Should I have? Thanks. Steve K8JQ
