REPORT OF POSSIBLE INTERFERENCE FROM ELECTRIC UTILITY TO AN AMATEUR RADIO STATION Logo
  • REPORT OF POSSIBLE INTERFERENCE FROM ELECTRIC UTILITY TO AN AMATEUR RADIO STATION

  • ARRL uses this form to receive reports about suspected power-line noise.  If you are experiening harmful interference and want to start a case with ARRL and receive individual help with an interference problem, read the information on ARRL's RFI web page, then contact us by telephone or email for assistance.

    Note on recording the RFI:  It is helpful to provide us with a recording of the noise you are experiencing, and you can send any recorded files to w1emi@arrl.org. When making recordings of the RFI, the recording should be at least 60 seconds in duration, and be recorded for both AM and SSB modes.  If you can provide a something in the frequency domain (e.g., from a spectrum scope), that can be helpful to us as well.

  • ARRL can best help you if you are knowledgeable about power-line noise.  Here are some helpful links and resources concerning RFI:
