Hi, I have just started using WSJT-X. I am unable to see any decodes of FT8 signals. There are plenty on the waterfall and the signals are audible through my rig speaker (IC-705). In the settings/ radio tab both Test Cat and Test PTT work. The green receive indicator on the main screen is showing about 60dB. Before trying FT8 I used WSPR mode and that worked fine. Any ideas what I may be doing wrong?
