RE: Mains Noise - any truth in solutions

["christopher purves" <CHRIS_PURVES@xxxxxxx>]

Thanks - I will give that a go although I think the comfort engineer is at
the house at the moment (I am at work) so asked him to check his end at
least. It is annoying it seems to come and go. At the moment it does sound
like adsl may be the culprit.

Am I correct in guessing that removing the adsl router would stop the noise
even without the filter ? That is there must be an adsl 'conversation'
going
on to get the noise?


Thanks for all the help !

Chris
