[RFI] LED Lights

[Dale Johnson]

Feit Electric at the LED’s that I have in the shack lamp and other places in the house.  There are two in the basement that I never shut off.  The shop lights are also Feit Electric.  My doublet goes over the house at about 30 feet, it’s 140 feet long with open feeders.  The yagi is a SteppIR at about 40 feet now and the tower base is about 35 feet from my shack window.  When I turn on the lights I don’t hear any increase in the noise floor here which is pretty quiet here for being in  a city.  Noise floor right now on 20 meters is about S-2 to S-3 on my K3 with no attenuation, preamp off.  If I turn the yagi South the noise floor increases, I believe it’s from my neighbors next door (200 ft) or beyond, but not from my own house.

1. What make and model… exactly.

2. How far are your antennas from those lights?

I can also say with 100% confidence that a NOISY fixture will cause a proximal RFI problem even if only one is installed.
