A high-amplitude whistler wave propagating through a current-carrying plasma decays into a low-frequency resistive quasimode and frequency-upshifted scattered whistler. In this process of nonlinear Landau damping a pump-wave photon absorbs a quantum of energy from the drifting electrons to generate an upshifted whistler photon. Upconversion occurs only when the drift velocity of electrons exceeds the phase velocity of the quasimode (..omega..
