[RFI] Sylvaniai LED bulb interference 20 meters too

[Cortland Richmond]

I put the one I took out of the bedroom in a desktop lamp at the operating
position and today noticed an S4 noise level on 20.  It is apparently
coming in through 12V powering the auto antenna tuners, since the rig's
attenuator cuts it down appropriately and it is there if I ground the
antenna inputs. No matter; I have a (brighter) 60W incandescent plugged in
now.
