Don't forget the rogue power supplies which seem to be cropping up in
ever increasing numbers. Could be on a large (or small) flatscreen
TV, low voltage halogen lights etc even down to the power supply of
the DSL router itself.
Recently had a case where one such noisey powersupply effectively
stopped the ADSL service for a whole street of around 50 houses, cured
the problem by cutting the UG feed to the building as the occupants
had gone on holiday (but it did take 5 weeks to get the T(echnical)
T(ransmision) O(fficer) to site). Quite looking forward to going out
to reconnect them so I can find out what this little gem is, probably
something obtuse, but that's the fun of the job..
