Hello all, I have just installed VarAC and HFmodem. my radio is a xiergu x6100, everything looks ok and the VarAC calls the modem ok plus radio CAT control is working. I am not receiving anything at the VarAC window but the radio is. If I go to VARA HF modem it shows the frequency as 20m band on the sound are settings but VarAC is set to the 40m band and has correctly set the radio to 7.105.00, the modem Audio input shows a signal approx -12db. In the the modem setup it show line in as USB audio device which I assume is correct as the pc sees the radio with 2 com ports USB for the radio. if I use the beacon button the radio transmit my call sign is 2e0bnl. still nothing seen in the VarAC window. Any help appreciated.
