JAY,

Check the Mechanical Connections of your Phone Lines.
If you are hearing a "Audio" Noise on the Phone Lines
then a 'bad' or 'dirty' Connection may be the problem.


Piggybacking on RHF's reply: What kind of telephones?

Do you have an "old" (POTS) type phone? One of the Western Electrics?

[If not, grab one at a yard sale/thrift shop for $1-$4.]

Disconnect every other telephone in your house, both power and telephone
wiring, and see what you get.

Like Bill, I'm tending to think that the dimmer may not be causing the
interference as much as it "introduces" the interference.

Also, I've seen a lot of wall-dimmers that have two blacks or two whites so
there is that (possibly).

Another possibility: Using the circuit breakers, try combinations of circuits
and dimmer switches and "other" electricity users. (I realize that is using
three variables but I'm not the one who has to do this dux!!.)

Have you double-checked that you don't have a flourescent unit going bad?
Come to think of it, the "fast blinking" from that would give out about that
frequency.

Let us now how this is going; it's an interesting probelm.

Also look for places that your Phone Lines and the household
Electrical Wires run parallel.

Finally put "Clamp-On" Ferrite Cores on the A/C Power Sources
for any Phone Equipment that you are using.

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?

Jay
