Although I haven't experienced this problem, W0IVJ and W0QE have
documented it quite well. I strongly suspect that it is a simple "Pin
One Problem" in the defective equipment (probably the DSL or cable
modem, but also in the CATV or DSL distro system). If so, it can
probably be suppressed a lot by ferrite chokes on cables connected to
the defective equipment. Chokes should be wound using the guidelines in
my "Choke Cookbook" for the frequencies where the noise is heard. It's
