For the life of me I can not get VARAC/VARA HF to transmit audio. the radio keys up but no audio is sent. Receive audio works. Everything else seems to work. I have the latest versions of both VARAC and VARA HF. WSJT-X works correctly.. The radio is a IC-746PRO using a RIGblaster pro. Any help would be appreciated. 73 Rick K3RJK below are some screenshots
