Change to a wireless lan, immediate problem will go away and you gain
flexibility in moving or adding devices. You should still sort out your
grounding and make sure it is up to code.

I know it is OK at the house, since I put it in and connected it to the
panel, but I am not sure about the pole.
Thanks for the suggestion. I'll call the local power company and have them
check it.
Also, after all the good suggestions I have received here, I am beginning to
have serious doubts about the ground system in the house.
I am thinking the following:
1) My 8' ground rods may NOT be an adequate ground. I'm going to get
together with the power company to check all this out.
2) The OLD ground wire which the geology students put in to the panel, and
which ended at the plastic water pipe that comes from the city main, may be
long enough, and oriented well enough, to act as an antenna. I'm going to
take that out today. It is at least 30 feet long (which never did meet
code).
3) I now agree with those who have suggested that the RFI may NOT be getting
to the router through any of the CAT-5 cables. However, by disconnecting the
CAT-5 that goes to the basement shack, it APPEARS, so far, that the router
is not effected when I'm on the air. Of course, however, there is the
"problem" that yesterday I added at least 6 more clamp-on filters to both
the DC feed that connects the wall-wart to the router (both ends) and to the
CAT-5 that comes from the basement (both ends and in the middle).
Those I added to the DC line from the wall-wart were looped at least 5
times, as was at least one at the CAT-5 that connects to the router, and
twice at the shack end (all I could get).
4) What is still bugging me is why the GFCI at the washer still "hums" in
time with my keying, although it no longer trips. I have not figured that
one out.
5) Concerning the coax to the antenna: it is a piece of RG-8, buried in the
ground and is about 50 feet long, looping around the concrete patio.
Although I have not checked it out thoroughly, it is getting RF to and from
the antenna...
6) I am also, now, very suspicious of the ground system in the shack. I'll
review all of it as soon as I can get to it, and will follow the suggestions
mentioned by you folks. Although I do have a #12 bare copper wire connected
to the amp and the coax that feeds the antenna, and to the electrical panel,
I am now not sure it is contiguous.
Again, thanks for the suggestions. I very much appreciate them. No matter
how long we have practiced in a field, it is always possible to overlook
something.
