Re: Further to my ADSL Faceplate Question

I meant from Traceys own transmitter :o)
Your theory is possibly true - also don't forget all those CFL lamps, LCD
T=
Vs and street lights that get switched on at nighttime, they're emitting
an=
d adding to the problem too.

If you haven't got an adsl master socket have you tried using a BT
accelera=
tor - aka an i-plate?  You can get them for approx =A38 and can help a lot

with these sorts of issues.

Also, I've noticed our adsl SNR improves in really cold weather - I wonder

if it's due to lower thermal noise in the copper wire - or maybe it's
coinc=
idence.

That's what Im seeing. Between sunset and sunrise, I see a change in SNR =
on
ADSL, and slower sync speed, from 6Mb/s down to 4.5-5Mb/s. I only see thi=
s
change when its dark.

My theory is this is due to the ionosphere becoming more effective and
increasing the 'skywave'

The overhead BT lines are acting as antenna, increasing the noise on the
line.

I would expect anyone with overhead BT lines would suffer from same.
