In plain language: Find RF interference by turning the complaint into repeatable evidence: note frequencies, bandwidth, timing, direction, mode, and what equipment or loads change with it.
Why the station behaves this way
Noise signatures can travel through mains wiring and radiate far from the source, so the loudest point in a room is not always the emitter.
A common wrong turn
A spectrum screenshot alone rarely identifies ownership or cause, and walking onto private property with an accusation damages cooperation.
What to do at the radio
Confirm the noise is external to the receiver, isolate your own circuits safely, use portable direction finding and near-field tools, keep a log, then work through the proper owner, utility, or regulator process.
Operating boundary
Use current equipment instructions, legal operating limits, the exact signal path, and observed conditions. A connector, software label, transformer ratio, or forecast value does not prove complete-system performance.
