We show that (i) the observed emission appears once the drain-to-source voltage, U-DS, exceeds the threshold value, U-TH; (ii) the resonant frequency can be tuned by U,,, in agreement with the current driven plasma instability model of Dyakonov and Shur; (iii) by applying a quantizing magnetic field one increases U-TH linearly with the magnetic field while the evolution of the emission signal is approximately a universal function of (U-DS - U-TH).
