No, the way the QDX generates a signal by modulating a narrow band carrier it can not support VARA. As noted on the QDX main page "QDX transmits a SINGLE SIGNAL, it is not an SSB modulator with associated unwanted sideband and residual carrier, or intermodulation due to amplifier non-linearity. QDX outputs a pure single signal."
