[Elecraft] K3 - FT8

[ANDY DURBIN]

I should have said that this explanation is only valid with WSJT-X split mode is not in use.   When split mode is used the situation is either simpler or more complex depending on your perspective.


In WSJT-X split mode the audio frequency is constrained to the range 1500-2000 Hz.   If the TX cursor is outside the range 1500-2000 on Widegraph then the TX VFO frequency is incremented or decremented in 500 Hz steps such that audio frequency remains in the range 1500-2000 Hz.
