A few questions to help fill in some details::
Do you live in the city or the country?
How close are your neighbors?
Are your utilities underground?
Does it have AC line nose characteristics?
Is the noise comprised of discrete carriers every 25 to 50 kHz that buzz or hum?
Does the noise go away with different weather (days with sun and dry versus
cloudy and wet)?

Subject: [RFI] WB Noise covering 40M
Recently I have been experiencing a spate of loud, wid band noise in the
range of roughly 6 to 9.8 MHz. Noise is virtually continuous, but does
stop occasionally for short periods. No consistent timing pattern that I
have observed.
I have tested with all local AC power shut off, so I do not believe it is
coming from any source in the house or ham shack.
Anyone have suggestions on where to look or what to look for?
Thanks.
