More noise from lamps.

This week I have been trying to find noise sources to get rid of so I
can listen to some quality shortwave.
First I found the Chinese CFL's to be horrendous and should be reported
to the F.C.C., as if they will do anything.
Last night I had another noise source to kill, a 3 way touch lamp that
uses an SCR. I turned it off thinking the noise would go away but it got
even louder with the light off. Picked it up and looked on the bottom
and sure enough, "Made in China.". The only way to stop the noise is to
unplug it completely, making about a 20dB improvement in the noise floor.
I don't know which other things make RFI this bad but so far "Made in
China." seems to be a warning label for total crap products.

Didn't we discuss this in depth 10 years ago?
