But the cable is twisted pairs and its not radio stations,
it the ignitions in the traffic thats much worse than
any electrical noise inside the house.

It being twisted will affect any noise it is subject to. It doesn't
apopoly soleley to i=gnition noise.

Never said it did, but ignition noise is in fact
the major electrical noise outside the house.

And the speed you get with broadband isnt determined
by the noise level anyway, its determined by the length
of the run of copper pairs in the street cable.

Precisely. The longer the run the more pickup from adjacent cables and
from radio stations.

It isnt pickup thats the problem, its the loss in the cable.

As well as the weaker the wanted signal.

You seem to be rather weak on the theory of radio.

Then you need to get your seems machinery seen to.

I suggest you study the implications of near versus far field signals on
twisted pair transmission lines,

Been doing that since before you were even born thanks.

and the choice of ADSL bins versus the signal strength of the few
remaining AM radio stations

Thats not what determines the speed you get.

as well as the variation of recieved noise level with the time of day.

Ditto.

Then a short diversions into interference suppression on modern cars
equipped with - yes - AM radios as well, still - should disabuses you of
any notion that you actually know what you are talking about.

You never could bull**** your way out of a wet paper bag.
