Power Line Noise Mitigation Form ver2

Power Line Noise Mitigation Request

Before submitting this form, take steps to identify the exact source of your interference. We request that you do some basic troubleshooting to narrow the range of possibilities and improve the likelihood that the noise issue can be successfully resolved. Your power company is responsible only for interference originating from their equipment. The ARRL can assist you in resolving other causes of interference such as grow lights, switching power supplies, electric fences, and neon lights through its publications and, if available in your area, its network of volunteer technical specialists. Here are some resources to help you identify the source of your noise prior to requesting mitigation.

Please refer to this ARRL link and take the recommended steps prior to completing this form.
