KD4IEN, I have had extensive experience with powerline noise in nearly 
every QTH I've owned (unfortunately).
This goes waaay back to when there was little information published 
about this menace.

Go to the ARRL website and order the book titled:

"The ARRL RFI Book" #9892

You will learn a LOT. You will be amazed how a rusty nut and bolt 
(which is NOT) connected to any AC, will cause LOTS of wide spectrum 
noise.

Luckily, Florida Power and Light have some GOOD RFI techs (some are 
hams) and they have done an incredible job turning my rural QTH from an 
absolutely unusable one to dead quiet!

e-mail me direct if you need immediate help getting started....

I have bad static here 24/7 and i have the station grounded with a 10
ft grounding rod ...but it's esp bad the higher you go, not as bad on
28.400 still there not as loud..., but 1.9 and 3.8 is like frying
bacon... any hints or suggestions???

A single ground rod is usually inadequate.

Not knowing soil conductiviy, a mixture of salt and warted pouted
directly adjacent to the ground, with a raised perimeter should show
changes.

Some use copper sulfate.

Lawn damage WILL likely result.

I use six 3/4 inch diameter copperweld rods AND a 500MCM copper buried
lattice for my ground.

YMMV

I'm not an engineer. I'd try turning everything in my house off to see 
if it
ends. Then try to use a portable radio to search for the source 
outside. Maybe a
fellow ham or hams close by could hear the noise and DF it. I live in 
the
country in Tn too & it could be in the power grid. Or an electric 
cattle
fence.Or a neighbors yard light. A lot of possibles

Vertically polarized antennas tend to pick up more human-made noise 
that do
horizontally polarized antennas. Full wave loops (closed) seem to pick 
up
even less noise and may exhibit some gain on received signals over 
those on
verticals and 1/2 wave dipoles.

What type of receiving antenna(s) are you using? What are the conditions
surrounding your station? ...urban, suburban, rural, commercial 
activity,
etc. Is the noise always 24/7 or does it go away at times?

Try to take special care and notice if the noise diminishes any? real 
amount
after a good rain. Often the power line poles and insulators are 
cracked and
after a rain, then can quiten down.
When I lived in WV, I fought power line noise for years and finally 
filed a
formal complaint with the state power commission and actually had a 
hearing in
front of an administrative judge. The power company noticed at that 
point that I
was serious. It got fixed. But it helps a lot if you can work with the 
power
company.
?Let us know a bit more about your antennas and the surrounding area.
?Also, there is a reflextor dedicated to RFI and many helpful hints 
available
there!
