I have been trying to figure out how to use WSJT-X "correctly" to work JA from Finland (OH). As I can transmit at 1840 and JA station can't, I would like to fix the transmit F at 1840 kHz and use split to receive on 1908. How do I do this with WSJT-X? Or do I simply need to temporarily remove the radio CAT control and manually set the radio to do this, use two VFOs + split.
