Hello Gary, hello OMs, @Gary: In your last post, the crucial tip was: I saw that USB-D2 was automatically switched on again and again. Now I have set the mode to USB in VARAC Settings and now everything works. Thanks to you all. HNY and 73

The Vara HF configuaration (it does not work) The WSJT-X settings (it works) I don't have a USB connection between the Ic and the PC
