There can be many reasons Fldigi does not ¡°print¡± with your setup.
?
One rookie error is to be in LSB data mode. ?All modes are USB-D now, even on 80 and 40m where lower sideband is for phone (voice).
PSK31 and CW will decode even if in lower sideband - but most modes will not.
?
?
Watch how much audio in getting to the sound card receive (Microphone level).
You don¡¯t want to ¡°starve¡± nor ¡°saturate¡± your sound card.
I presume you are using the built-in sound card in the rig.
?
Watch the sound level settings in the MENU of the rig.
That DIAMOND in bottom right of Fldigi waterfall should be GREEN, not yellow, red or black, when centered on a good signal.
?
We usually advise getting the receive audio at about -20dB if you use the Fldigi Rx monitor level.
?
ps - I do not own or use a Yaesu Ft991A but owners of that rig should advise what to look for.
?
If you see audio in the waterfall, and click on it, what happens if the mode is what is being sent?
