>Greetings all,

>About a month ago I posted a message about an intermittent RFI problem on
>the AM BC band and 160M (which shows up spaced at approximately 138 KHz
>intervals). I had continued to try to track it down as time/WX permitted
and
>had narrowed it down to my house and the neighbor behind me. Yesterday the
>neighbor's jr. op was out mowing the lawn so I went over and talked to him
>after he finished. It turns out that he came home from college about the
>time the RFI started. He brought his clone computer home that they had
>bought for him last fall when he went off to school and started using it
>here. I have checked from their QTH and the RFI seems to disappear
>completely with unplugging it -- now I need to get on the landline with him
>and check from my QTH. I had him unplug it as a secondary test because when
>it was on it _completely_ wiped out the AM radio in the hall outside his
>room with broadband noise! (BTW the computer is an "Alaska" brand: PS says
>"Made in China" as to be expecte!

>Does this sound like it could be the culprit, and if so, what's the best
way
>to get it resolved? (The family is very cooperative and the system is less
>than 1 yr. old, so the question would seem to come down to whether the
>dealer or the manufacturer is responsible if I can prove that this system
is
>the source of the RFI.)
