General exam question G2E04

Which of the following is good practice when choosing a transmitting frequency to answer a station calling CQ using FT8?
- A.Always call on the station’s frequency
- B.Call on any frequency in the waterfall except the station’s frequency
- C.Find a clear frequency during the same time slot as the calling station
- D.Find a clear frequency during the alternate time slot to the calling station (correct answer)
WhyGood FT8 practice when answering a CQ is to find a clear frequency during the alternate time slot from the calling station. Good FT8 practice when answering a CQ is to reply on a clear frequency during the alternate 15-second time slot from the calling station, since FT8 stations transmit and receive in alternating windows and replying in the same slot as the caller would mean neither side is listening at the right moment, answer D. Calling directly on the station's own frequency or in the same time slot works against how FT8's time-division scheme actually functions.
