Please read the Power-line Noise FAQ and follow the steps set up by the ARRL and FCC to efficiently handle power-line noise interference complaints.  If reasonable efforts have been made to try to resolve interference directly with the power companny and it is not able to correct your noise, read the FAQs and applicable articles, then contact the ARRL for help, providing the information that the FAQ says is needed for ARRL to work on the case.

Please understand, the ARRL does not have any authority to enforce FCC Rules under federal law. Only the FCC is empowered to enforce its rules in the United States. The ARRL Laboratory Power Line Noise pages are our best recommendation on how to resolve a power line noise problem. However, once a complaint becomes an FCC enforcement matter, the ARRL no longer has control of how the complaint is handled.

Build equipment to help locate power line noise 

• Adapting a Three Element Tape Measure Beam for Power Line Noise Hunting
  QST, May 2007, p 28
  Provides construction details on a low cost and easy to build antenna for locating power line noise.  This versatile antenna project can be adapted for a variety of frequencies and receivers.
• Attenuators can be essential for RDFing power line noise – especially if your receiver doesn’t have an RF gain control.  Although attenuators are often a popular Hamfest and flea market item, many hams prefer to build their own.  Here are three construction projects for doing just that:
