This report examines the potential for heating a layer of the ionosphere by beating two high‐power RF pumps at the local plasma frequency. Simple scaling laws for the heating efficiency and final temperature of the layer as functions of the pump intensities and frequencies are found for both copropagating and counterpropagating pumps. The results are compared to single frequency heating by collisional absorption (inverse bremstrahlung) near the resonance layer.
