The paper discusses immunity of an airborne radio communication system against low and high power interfering signals of power electronics. Modern avionics power switching power power electronics can provide undesireable responses which requires immunity tetsing of the radio receiver‥ The paper focuses on interferences which occur in the chain of intermediate frequency processing and the effects which compromise the radio immunity. Interferences are measured as triggered by both strong and weak signals. All analyses and methodologies are in accordance with recommendations and standards valid for communication systems in VHF band (118 MHz – 137 MHz). Results are presented for a fully certified airborne radio communication system.
