This light quest; I don't understand why I'm the only person actually doing
something instead of complaining. There's the problem, people complain but
don't actually investigate, instead complain with no resolution. I will
re-iterate, everything electrical causes RFI, even the SUN. HF black outs
caused by solar … SUN.
Just because something is written doesn't mean it's fact or true. Get
involved and ask the right people, stop complaining.
73,
