Thanks, Dave, for your detailed reply -- lots of good tips. You're right,
of course. It really isn't my responsibility if the cable company is
putting out equipment that can "listen in" on my HF transmissions. I'm sure
my equipment is clean. Actually, before I go out and buy a collection of
ferrites and suppressors, I think I'll just encourage my friend to complain
to the cable company. They should be the ones fixing this.

Or, am I being naive here. Could they make more trouble for me than it's
worth even if I am "innocent."
