Installation of DSL has caused terrible overnight
buzzing from the 500's to about 1000kHz.

Phone company made adjustments at street and
house.

Buzzing on portable radios re-radiated in
vicinity
of the four phones in the house.

On the outdoor phone line, portable radio reveals
that buzzing is propagated parallel to phone
line, not perpendicular.

Buzzing the loudest near our strongest overnight
signal at this location, 710kHz (710 KIRO/Seattle
50kW U2).

Why the buzzing only occurs overnight I haven't
figured out.

During the day = a hissing or whining sign on
weaker 1kW frequencies, even higher up the dial
(e.g. 1400kHz).

The old radio shack terk clone does not even help
that much at night.

Any info on what to tell phone company to do
would be very much appreciated, thanks...tom:

Hi:

I'm sorry I am no help re your problem... but I will be reading the mail as I am curious about your EMI situation and the DSL installation.? Does your phone line come to your house via buried cable or is an overhead line from the pole?? I have a DSL installation at this location .... in fact the outlet for the DSL modem and the modem itself are located about 1 1/2 ft from my operating position ..... I experience no noise from it what so ever .... however, I will check a little more closely on the frequencies you mention.? By the way the phone line here comes in via a buried cable (6 pairs) the local telephone company installed about 3 or 4 years ago.

Now I did have some noise problem from the telephone installation about 2 years ago.? The distribution within the house comes from the power panel.? That is they terminate the lines from outside and distribute lines within the house from that location.? At one point I had 4 lines terminated from outside and 5 cables going off to different locations within the house.? Over the years it became a rats nest of connections and wires.? Even when the phone company installed the new underground cable from the lane the rats nest remained.? Finally I couldn't stand it any more and I found a couple of 24 place barrier strips in the junk box and I mounted them on the wood backing of the power panel.? I then methodically terminated the incoming lines and the internal lines to the barrier strips.? I then drew up a schematic with the termination numbers.? I then cross connected the terminals to effect the desired distribution.? I used a 'LED' test tool to make sure the polarity of every line showed 'green' at every telephone jack.? Magically the noise stopped and the terminations really looked professional.? When they came to install the DSL service the installer was amazed at the setup .... 'this can't be our work' , he said!
