The RFI Troubleshooting Guide RFI Troubleshooting Guide – ARRL New England Division now has a list of the power company contacts for hams to report power line noise-related issues. Hams are encouraged to contact New England Division RFI Teams prior to doing so to make the team aware of the issue, so that they can follow up if necessary. Noise thought to be coming from power company hardware may actually be from another service on a power pole, like a leaking television cable, so try and gather as much information, with the help of the RFI team if needed, to understand the source of the noise. We expect to need to update the maps and contact information from time to time as service areas and company relationships change over time. If you see that we need to change some information, please let us know at email@example.com.
