I need a refresher course on Part-15 and how the rules might apply to
solar panel RFI affecting frequencies below 30 MHz.
According to section 15.3m (paraphrasing here) harmful interference is
defined as ANY RADIATED EMISSION that interrupts radio communications to
the amateur radio service.
Assuming the solar panel system components are classified as
unintentional radiators, the emissions limits below 30 MHz pertain to
conducted emissions and to the best of my knowledge, do not include
So the question is whether harmful interference as defined in section
15.3 (m) overrides the fact that there are no radiated limits below 30 MHz?
Do I have that right?
*Harmful**interference*:/§ 15.3 (m) Harmful interference. Any emission,
radiation or induction that endangers the functioning of a radio
navigation service or of other safety services or seriously degrades,
obstructs or repeatedly interrupts a radiocommunications service
operating in accordance with this Chapter./The rules for nearly every
licensed radio service prohibit harmful interference and that includes
the Amateur Radio Service.
