We all know that dimmers can cause huge electrical interference but I've got
a strange situation right now that I can't figure out. I've got several
dimmers in my house and any one of them causes a cyclical buzzing in my
phone line, even the hard-wired phones. That's strange enough, but this buzz
is not constant...it alternates on/off/on/off with a constant rhythm...about
one second on then one second off, and any one of the dimmers causes the
same noise to start. It seems as if the noise is actually coming from one
source with some cyclic pattern, yet any of the dimmers introduces it into
my phone lines. And it seems odd that this affects my phone lines...not my
am or sw radio reception.

Any ideas where I could look?
