[Yaesu] Plasma TV interference??

John and group

I have a Philips 42 inch plasma tv and it kills 40 and 75 meters for me.
The noise level is S-9 and I only hear the strongest signals over it.  What
you describe sounds
like the interference I'm getting.  I am lucky though, I can turn mine off.
I have sent an email to Philips but I don't expect a resolution from them.
I bought this thing
in 06 and I am just getting back into some hamming.  I can't always shut the
thing down either since other people in the house like to watch the tube.  I
would be really
interested if you can come up with a solution.  By the way, I'm using a
Kenwood TS-870 and my noise blanker has no effect either.

I was trying to run the Illinois QSO party today and 40m was getting
clobbered by something causing an S9 noise level.  I wonder if it is a
plasma TV in the area.  Does anyone on the list have experience with this
type of RFI?  The interference I had was a buzzing/hash type noise that
covered about 40khz of bandwidth.  It would occassionally disappear for a
few seconds and then come back.  The 40khz of bandwidth that it did cover
would move up or down the band slightly across time.  Does this sound like
plasma TV RFI, or does anyone have an idea of what could be causing a noise
like this?

The noise blanker on my Yaesu FT857D didn't do anything on this noise, and
for a little while a S9 clicking noise showed up that the noise blanker did
nothing on either.  Kind of a disappointing NB in the FT857, I will have to
say.
