[RFI] pleasant surprise today from Solar Edge

[Cortland Richmond]

Our problem in such cases is still the Commission's reluctance to 
enforce the rules against causing harmful interference regardless of the 
maximum permitted level of emissions.

I note that Class A ballasts are still being sold without even a label  
they're not to be used in residences.

The FCC rules on emission control ONLY conducted emissions ON THE AC MAINS, so any noise present on that loop did not have a specific limit.  So, the early systems complied with the letter of the law.FCC has rarely been required to even assess an individual circumstance as harmful interference, and when it has, that assessment has been all over the map.  I do know they will consider the level of interference, the frequency occupancy, a comparison of that level to median values of man-made noise (typically S6+ on lower bands, btw...), whether the amateur can make use of frequency agility, how often it occurs, time of day and possibly even the phase of the moons orbiting Saturn.
