I am unable to get a signal out from my VarAC setup. I am using VarAC V6.4.15 and VARA HF v4.7.1. Radio is Kenwood TS-480. I use a USB sound I/F. Is is a remote setup using Remoterig RRC-1258 Mk II units. Computer is a Lenovo Y50 running Windows 10 Home, fully updated. With this setup, I have been using VARA HF for a long time together with Winlink Express. Never experienced any issues. After VarAC startup, I try VARA HF -> Settings -> SoundCard. Clicking on Tune gives no audio signal into the radio, no matter the DriveLevel. The radio goes into transmit, but no output. Receive work well, and I get the occasional beacon and CQ displayed. The VARA HF and radio settings are the same as while using Winlink Express. So, I am pretty sure that the problem has nothing to do with radio or PC & Windows settings. As far as I can see, the only difference between running Winlink Express and VarAC, is the radio setup. For Winlink Express, "Kenwood Amateur" is selected together with PTT Serial Port set to "K3". For VarAC, "Kenwood TS-480" is selected. CAT control apparently works the way it should, frequency setting/readout and PTT works fine. All settings are as indicated in the manual. Any suggestions? 73, Per-Tore / LA7NO
