Because the interference is coming from another house, moving the antenna onto the roof wonít help much.

I have heard stories about cheap Chinese grow-lights that make tons of RF noise. They are commonly used by hemp operations.

To trace the source of the interference, you would need a VHF receiver that can measure the strength of the noise and a directional VHF antenna. An FM receiver canít help. An AM decoder is needed. The most common AM receiver would be a scanner with an aircraft mode. Another choice would be an all-mode amateur rig that covers the two meter ham band. Then itís make measurements from several locations until you can triangulate the source.
