A DXer friend of mine has a strange noise that has recently came up.  A 
link to the wav file of the noise is listed below.  I've never heard 
anything like it before.  I'm wondering if this is what the new plasma TVs 
sound like?  Anyway, it's definitely from outside of his home.  It might 
help him out if someone on this list has heard a noise like this before and 
can I.D. it so when he tracks it down to a neighbor, he can ask about 
certain devices before resorting to having to turn power off to evrything 
to figure it out.

Thanks for any help!

Hi Ed,

Thanks for the reply.

Here is the link: http://www.qsl.net/hdxa/rfi/noise.wav

I tried for a while last night to find the source.  It
seems to be across the street along 2 or 3 houses.
I'm just using a SW receiver tuned to 29Mhz with the
antenna extended horizontally.  I know the way I hold
the receiver effects the signal and direction.  I can
detect the noise down to 14Mhz on the SW receiver.  On
my 80m delta loop I can detect the noise down to 10mHz,
but really notice it at 12mHz.

This morning I turned off the main breaker to my entire
house and the noise was still there.

Thanks again,
