[RFI] need ideas on hunting down QRN-like noise source

[Bill NY9H]

did you notice any TV set empty boxes on your neighbors' curb?????

My next door neighbor bought a set three years ago..
it's up in the master bedroom. Whenever it is on, it raises 20 meter noise 
to S7.

The beam pointed right at their house , about 50 feet from the antenna.
It was/is confirmed by looking out a window and seeing it turned on.
She likes Oprah, while she generates a smaller amount of pulse noise with 
her treadmill....

recording the noise and posting it sounds like a great idea..
I have a recording of my mast mounted cctv camera ....!!!!a gurgling noise 
on 20 meters....

It was suggested I might try to 'fix' the issue, however this home is also 
a haunted house !!!  Several years ago the babysitter told the homeowner 
that all the walls were making moaning and wired noises. !!!  she should 
have said all the Nutone built in intercoms were making noises. They called 
the builder !!!
who told them to call ME.
