The paper presents the results of experiments concerning the impact of nonlinear clutter of powerful nanosecond pulses on radiotelephones, causing them to malfunction, and on nearby communication transceivers, for the deliberate distortion of signals radiated into space and for forced switching of the transmitter’s generators to a mismatched load with subsequently causes them to go out of service because of overheating. Some unique features of this type of clutter are discussed, as well as advantages of radio suppression of telecommunication systems with the aid of such interference
