You're doing wonders for my confidence in NTL.

I now wonder what they've done in our street cabinet?

Anyway, the screen is obviously not isolated in the cabinet, otherwise I'd only get aerial pickup and not this 50Hz earth loop problem.

Listening to your horror stories my 4V ac interference seems tame.

I wonder whether wrapping ptfe plumbing tape around the coax thread on the back of my modem would act as a highpass filter; i.e. pass through the cable signal but open circuit the 50Hz? A coax is a waveguide after all.

Maybe I'll just get an engineer out.
