[RFI] LED Bulbs

[Dale J.]

David, it still puts the burden of finding, contacting the owner and trying to get him/her to fix or get rid of the offending device, which in my opinion should have never been on the shelves in the first place.   

I have spent quite a few hours tracking down power line noise and defective street lights, always I've been successful, but it took me time to do and at hours when most people are sleeping.  Wandering around in darkened streets looking for a street light blinking on and off.  That's all fine and good, but for me to enter someone else's house and order them around so to speak, like could you turn off your TV so I can check to see if it's the one that's making the interference and yes I have done that, thankfully my neighbors are understanding.  Can you imagine me telling them you are going to have to stop using your TV because it's interfering with my ham radio operation, hi…I don't think so.  

I don't like going into other peoples houses and ordering them around, I wouldn't like it and I don't expect them to like it either.  This is my point, the junk has to be stopped before it gets in the field.  Too late now for me at least until the TV goes on the blink, but there's a lot of this stuff that is still in the factory waiting to be shipped OR on the engineers note pad waiting for the production engineer to rev up the assembly line.  

All it would take is one time where the FCC examiner would walk into a big box store, randomly select a LED light package or dimmer etc, have it tested and order all that brand of light to be taken off the shelves.  After that the company would spend the 2 or 3 cents or a nickel more and make it quiet.  But its not going to happen.  This stuff is going to continue to be imported or mfg here, sold and enter our neigborhoods, probably even more and worse in the future.

Chinese generic things... one is still in use and perfectly quiet even with a sw rx with ferrite rod antenna right next to it... the other one got sent to the arrl lab for dissection as it radiated all over the place, so I lost a few bucks, but maybe the arrl got some experience with bad bulbs.
