Thanks, Gary. I was not aware of the 8 kHz operation of the 'new'
electronic ballasts. I still think its a stretch to place them under Part
18, but the FCC has ruled. The electronic ballast people must have a
strong lobby. I give up.
When we had this house designed and built out of the High Park Fire in 2012
where we lost everything, I'm glad I specifically specified absolutely no
LED's, no florescent lighting, no CFL lighting, and no (accessible)
SMPS's. I won, but the new appliances are full of SMPS's not to mention a
few touch panels. Over the five years we've been in this new house, I've
managed to tame 'most' of the nasty little gremlins for radio astronomy and
amateur radio. BUT........, when I really want to dig into the noise for
radio astronomy, ALL PC's and laptops must be OFF.
Enough.......... Read my 'rant' on my QRZ page (WØLEV) regarding the
modern digital world and FCC (last paragraph of the QRZ page)..
