Well, I shut off the breaker again and went through room by room with my
portable as I switched them back on. The buzz was evident to some degree
throughout, but most notably in the room just where the service enters the
house, and definately at the service panel. So, I guess that noise is
radiating from the powerline, throughout my house, and into all my stuff? I
don't know, this sucks. I had powerline issues at my last house that never
got resolved, but this time my antenna is quiet, it's just noise in the
house. I'm not sure what my question is exactly, but does anyone have any
ideas?

Hello Brian,
I had a similar problem and went through the same procedures you are going
through. Since the source of the problem in not in your house, it is
external. I took a very small portable, tuned it to an AM frequency where
there is no station transmitting, and started walking the neighborhood
listening for noise. I found a tremendous buzzing noise about a half mile
from my house and it was coming from a cluster of 3 power poles. I could
not identify which pole it was exactly because they were within a street
width of one another. I sent a letter to our local power company, drew them
a map of where the noise was coming from, and told them about the problem.
They responded in about one week, checked the area of the poles and
replaced a lightning arrestor on one of the poles. The noise source in my
house dropped from S9 plus to about S3, a dramatic improvement!

If you locate, as close as you can, the source of the problem, chances are
very good the power company will take care of it. Best of luck.

Thanks Al. I was hoping I wouldn't have to hunt down power poles again. I'm
not sure if I'd get much response from the local utility company anyway. I
called this morning about all of the limbs and vines hanging over the lines
out here and they said that it was my problem. I'm not sure if that is the
case, but I will look into it. Anyway, I found that listening in sideband
makes it a little more bearable and without the sudden deafening buzz in my
ears every few kilohertz. I don't plan on being here much beyond a couple of
years and I will go out of my way to find a place out in the country my next
move.

BRIAN,

EXTERNAL POWER LINE AS A NOISE SOURCE:
If you are having a problem with Noise getting into your Radio
Equipment 'via' the Power Lines. You can "Isolate" the One
Circuit that feeds your Equipment and 'install' individual
Feritte Cores on each Leg of the service (all three wires).

INTERNAL HOUSEHOLD NOISE SOURCES VIA HOUSE WIRING:
Buy a bunch of Clamp-On/Snap-On Ferrite Cores and go around
placing one on each Electrical Appliance; while Checking for
Noise on Your Radios.

REMEMBER: You Can NOT Solve All RFI/EMF Noise Problems . . .
But You Can Eleminate The Big Ones - And That's A Start )

Could you by chance explain exactly what you are refering to here, if you
wouldn't mind: You can "Isolate" the One
Circuit that feeds your Equipment and 'install' individual Feritte Cores on
each Leg of the service (all three wires). Sorry, I am just not very
familiar with this stuff.

BRIAN,

This depends on many things. Your House and its Wiring.
Your 'ability' to do your own Electrical Wiring to Code;
or your need to have it done by a Licensed Electrician.

Basically, If you have all your Radio Receivers in one Room
and the Electrical "OutLets" in that Room are on One Circuit.
Then you go back to the Main Circuit Breaker Box and 'follow'
that "Circuit" out to a point where you can install a Metal
Electrical Box. You place your Ferrite Cores in this box.
One on each of the Wires: Black, White and Green.
Please Note: This can be a lot of work.

Another 'solution' is to "Place" Clamp-On Ferrite Cores on the
AC Power Cords of Every Piece of Equipment in the Room that
you have your Radios in. I will repeat my self Every Piece
of Equipment in your Shack. For both my Grundig Satellit 800
and Icom IC-R75; which use External Power Supplies. I use a
Clamp-On Ferrite Cores on the AC [Input] Power Cords about
6" from the AC Power Plug. Then I also use a Donut Magnet
on the DC [Output] Cord about 6" from the DC Power Plug.
Note: These Donut Magnets can be bought at RadioShack and
'look like' a 1"x1/2"x1/4" Ferrite Toroidal Core; but they
are Magnets. aka: Refrigerator Magnets

TIP: If you buy/use the big Clamp-On Ferrite Cores; after
the First 'pass-thru' you may find that you can Loop the
Power Cord around for a Second 'pass-thru'. Keep this Loop
small and close to the Body of the Ferrite Cord. Use a
Plasitc Cable-Tie if need to hold everything together.

Thanks Roy. I am not familiar enough with the ins and outs of electricity in
general to go to some of the lengths suggested myself. However, I like the
idea of placing ferrite chokes on all of my equipment and it sounds simple
enough. Also, when checking the individual circuits I noticed interference
from several computer and stereo components, routers, and so on. So, I will
go ahead and place chokes on those things as well and see if that helps.
Thanks again. 73

Look for a compact fluorescent lamp. They will put out a powerline buzz,
often every 20-40 kHz, as that's the frequency the electronic ballasts
operates at.

Lamps with touch switches are notorious for that, too.

And somebody even found that their doorbell transformer caused problems.
They're designed to not blow the fuse or burn up even if there's a
fault, so they can arc away forever.
