Thanks for all the suggestions, I do appreciate the input. I think Dave hit
the nail on the head, namely that all routers will PROBABLY generate
something, some worse than others. Dave, I read your reply over and over and
I am quite amazed at the tenacity you went after your problem. Didn't sound
like an easy bug to chase.
Now on to what I did to MINIMIZE my RFI problem. I say minimize because
it's not totally eliminated, but it's at a point where I can tolerate it.
My DSL modem and router are about 10 feet apart and I make all my own
cables, so I know they are made correctly. I attempted removing all 4 to see
if one of the cables to a PC was at fault and none of them were, however
when I removed the shorty cable between the modem and the router, the noise
stopped (the cable is only about 20 inches long). I tried all kinds of
things ( and yes, I did put a 6 foot cable in to get away from near
resonance on 2 meters), like wrapping the cable in foil, making it into a
ball and just moving it around in different positions, etc., but when I used
an iron core bead on the ROUTER end and wrapped as much of the cable around
it as I could, the problem all but disappeared. Putting the iron at the
modem end had no effect. The other thing I did was work an even trade of my
old Dlink router with my neighbor for his old Linksys router. The Linksys is
in a solid aluminum case (well shielded) and initially helped my problem.
This little Linksys has NO plastic on the outside and seems to be a bit
quieter because of it.
Lastly, I have all my antennas either outside or 20 feet away up in my
attic and on 2, all were affected. I will admit that if I put a rubber
duckie on my TS2000 and listen on 2, it was really bad. So the outside, more
distant antennas do help. I've only noticed this problem on 2 meters, no
where else. HF and 440 seem to be clean.
As Dave suggested, the problem is indeed coming from the routers, whether
it be the power supply or just the electronics of Ethernet, I'm not sure.
I'm guessing the electronics of the Ethernet is generating the spurs.
I think the Dlink DI-604 is a fine router, it has given me years of perfect
service but it looks like time to make a change. I may end up going through
several different wireless routers before finding that fits my operation,
but I always have the Linksys to fall back on.
Hope this discussion can help others.
Thanks again for the really great suggestions and Happy Holidays to all.

After several months of just not listening to my 2 meter base station, I
finally took time to find the source of the interference that held the
squelch open on the repeater channel I listen to most often. Turned out it
was my Dlink DI-604 router. I borrowed a Linksys NR-041 router from my
neighbor and it works a little better. I can now listen to the 145.390
repeater, not because the Linksys puts out no RFI, but only because it
puts it out in a different place (mostly in the 146.46-146.58 range). I
will probably invest in a newer router, probably wireless. Question I have
is does anyone have any experience with the new breed of wireless routers
that are reasonable clean in the RFI/2 meter spectrum? Thanks.
