[RFI] Help with a noisy touch lamp

[kd4e]

Ron,

	I took the liberty of copying your post to the RFI list. 
Very knowlegeable
and helpful Hams there.

	My recollection is that touch-lamps have always been a 
nightmare for RFI.
I don't know that there is a cure.

	You might try several turns of the AC cord around a toroid 
and maybe some
bypass caps on the circuit board.

	The problem is that the circuit uses the metal base of the 
lamp as a form of
capacitive "antenna", making it difficult to tame the beast 
without disabling the
"touch" feature of the lamp.

	BTW:  Have you tried a http://ixquick.com or 
http://clusty.com search?
You might include QST in your search as someone may have 
sent them a cure
to publish.
