[RFI] FCC RFI Question

It may depend who you contact. Hams that call the FCC toll-free number may be told that, but if Amateur Radio is mentioned, the case should be shuttled over to Laura Smith.  Those that work with Laura Smith are usually funneled into the process ARRL has worked out with the FCC. The first step of that process IS to work with the neighbor or electric utility.  In cases involving neighbors, ARRL and the ham often agree that skipping the "ARRL tries to help first" step is appropriate.  Once these initial steps are done, it has been shown that reasonable attempts were made to resolve the case. ARRL helps establish that the level of and nature of the noise is actual harmful interference and documents the attempts made to resolve it. The FCC then sends an advisory letter to the suspected noise source operator.l

If you make a complaint to the FCC they will tell you to work with your neighbor to resolve the problem.  In other words you are on your own.  

With the unfettered RFI, radio will die a slow death as the RFI becomes worse, that is unless you live far away from neighbors.

I was wondering how the FCC measures the level of RFI emanating from a distant device to determine whether it's above or below FCC limitations?

The reason I ask is that the RFI emanating from the device might meet a certain criteria when measured some number of feet from the unit, but the bottom line for the ham is whether the noise is still heard on his or her receiver.

That brings up the question of whether or not the FCC deems a certain level of RFI as "acceptiable"? My neighbors solar panels generate RFI ranging from S-5 to S-9 throughout the day and even at lower levels, the noise makes S-9 signals difficult to copy.

This video demonstrates how intrusive it can be at S-5 levels: https://www.youtube.com/watch?v=yc4uMkWYYBc
