Excessive Band Noise

[pastormg]

Hi Guys, when I got home from work last night I noticed on my K3 and a hexbeam that 10 through 20 meters had about a S-5 to S-7 noise level.  It was higher on the higher frequencies and lower on the lower one's.  I don't think that I have an RF problem because it just seems it is band noise.  Is anyone else having the same issue?  I turned on my K3 this morning before I left for work and it was not any better.  Any suggestions or help would be much appreciated.  Mark KB3Z

New plasma TV in the neighborhood?  Does it have a particular bearing
when you rotate the beam, can you knock it down with the
front-to-back?  Sudden appearance would suggest a single source.  If
not it may be something new in your house.

You'd probably get far more useful information from the RFI-reflector
archives.  There is lots of information there on all sorts of
RFI-causing devices (water bed heaters, plasma TVs, heating blankets,
fish tank heaters, etc etc etc) and what each one tends to sound like
... or look like on a spectrum analyzer if you have one.
