As others have said, you should try to attenuate the noise at its
source. If it is radiated, you need a better PSU. If it is coming out
on the PCs AC line, line filters might help.

If the PC and KGO are not in the same direction, some sort of
directional antenna might help.

Of course, the ultimate solution would be to move to SF and get a really
big signal. But there are problems with that, too: I live abt 3-4 miles
west of KNX (50 KW, 1070 KHz) and my problem is avoiding it, not making
it stonger

Yes, I've had that experience with close stations. You can probably listen
to it through the bed springs. :-)

Attempts to shield the AC with the RS ferrite block and a barbell weight
failed. See comment about household circuit dependency in my just posted
responses above yours.

Wayne,
You may wish to get one of those $5 circuit analyzers from your local
Lowe's/Home Depot/Tools R Us (yes, I realize this probably means a
drive to Grass Valley) and check for open ground connections on all
your sockets. I had grounding issues at my home and after getting a
shock while adjusting the hot water in the shower brought in an
electrician. He found many problems such as the hot and return
shorting on the bathtub (behind the wall of course where it can't be
seen) and most of my outlets did not have a ground. Had the house
re-wired and it got a bit more RF friendly - hope you find your issue
and don't have to rewire the house.

BTW, Nevada City is a nice place to call home - if you bump into
Mayor Arnett tell him that Howard from LA says hi.

Ah, you know about us. I'm not a ham, but I will be speaking to our local
club in January about radio astronomy. I used to have my hair cut by the
former mayor. I'll have to ask my present barber if he frequents her shop.
Maybe he attends the ham meetings. I only go to them when I want to promote
RA, which has been 3 times. Although I went a few weeks ago to find out if
anyone had a Icom R7000 rcvr. No luck. However, my opportunity to buy one
disappeared within a few days of that meeting.

I may have one of those analyzers here somewhere. Lowe's is a long way from
here, but we have one very good hardware store that would be a good candidate.

I would like to relate my experience. As you
did, I carefully selected a new computer case
and power supply from the stock at redacted,
paying careful attention to the FCC logo on the
power supply. After moving the mother board
over and turning it on, it completely wiped
out reception of the local 5kW station on 550 kHz.
Fortunately, I had picked up a couple of surplus
Corcom line filters (Model # 10ESK7)at a local
hamfest three years earlier (it pays to collect
junk). I spliced it into the computer power
cord and it cured the problem completely.

I don't have any experience with the Radio
Shack line filter (Catalog # 15-1111), but it
looks like it might do the job for you.

This is really weird. The noise stopped! There's no question that when I
first noticed this some weeks ago that it was linked to turning the PC on,
and would disappear when I turned it off. I haven't changed anything.

Not to worry. It will likely return :-;

Just as a remote possibility, have you changed resolutions, or refresh
rate on your monitor?

Good question. I recall trying to change, unsuccessfully. Hmmmmm.

Classic indication of a bad ground, or a ground loop.

I haven't changed anything.
And the problem hasn't gone away either.

Well, I did change something, as I finally recall now (as prompted by M.
Coso's post). I did put a new (used) monitor on that computer about 10-14
days ago. Maybe it had some affect. Dunno. I guess I could always try the
original one. Tomorrow.
