Which of the following is good practice when choosing a transmitting frequency to answer a station calling CQ using FT8?
Always call on the station’s frequency
Call on any frequency in the waterfall except the station’s frequency
Find a clear frequency during the same time slot as the calling station
Find a clear frequency during the alternate time slot to the calling station✓Правильный ответ
Объяснение
FT8 stations alternate 15-second slots, so when you answer a CQ you will be transmitting in the slot opposite to the station you called. The frequency you choose therefore has to be clear during that alternate slot, not during the slot in which you heard the CQ.
