Radio Frequency Interference (RFI)

This is unwanted Electromagnetic Emissions in the radio reception bands (LW, MW and FM).

This is perceived as:

  • Poor radio reception - the radio is unable to detect the required radio station as the signal strength is reduced.
  • Distortion - the audio is distorted and whistles are heard over the radio station signal.
  • Transients - pops and thumps in the audio signal, often caused by switches and solenoids.
