FCC Letters about RFI

  • The "Pettit letter" was written to ARRL General Counsel Chris Imlay concerning an ordinance in Pierre, SD that sought to regulate interference. It shows that the local governments can't regulate interference since only the FCC can.
  • The "Haller letter" was written by the FCC on behalf of an amateur whose application for a variance that was denied based on possible interference to home entertainment equipment. This letter also states that the higher the antenna, the less potential for interference to home entertainment equipment.
  • The "McNamara letter" which was written to the neighbor of a ham who insisted that the FCC laws on interference were too lenient and should be strengthened. The FCC explained to the non-amateur that the current interference regulations were adequate and should not be changed.
  • The "Smith letter" Re: Ordinance Regulating Radio Frequence Interference
