Bruce, I had the same problem but only with 10m, 2m and 6m.  I solved it by
installing a clip on torroid around  the RJ45 cable just behind the modem
and moved it up and down the cable until the signal went away.  In my case
it is a ethernet switch but sounds like the same problem.  Also, I had to
redo one RJ45 connector since the signal would change if I wiggled it.  The
torroid really knocked it out though and  I think RadioShack carries some.
The one I used was from an old junk power supply.
I haven't ran accross a shielded RJ45 cable yet but surely someone makes
one.  Hope this helps a bit.
