I'm having troubles with VarAC and my FT-991A. My setup works fine with Winlink and has previously worked with the first VarAC release. Since the 3.x release I cannot transmit but can receive normally other stations calling CQ. The FT-991A is configured for Data. OmniRig works perfectly and frequency is synced ok. My audio codecs are ok for I use them with Winlink. When I use the VARA soundcard tune button in Winlink all works fine. I can adjust the ALC level without any problem but this is not possible with VarAC. I do not understand why VarAC is not able to pipe the audio output codec to my FT-991A.
