04/04/2022 22:08:00 - The PortName cannot be empty.
Parameter name: PortName
at System.IO.Ports.SerialPort.set_PortName(String value)
at VarAC.VarAC.Load_configuration() VarAC seems to be working fine, but this is before and after each QSO. I think it just started or I've not been paying attention to it. Thanks
