Electric 'noise' in my apartment

    I have a really annoying problem in my apartment. MY TV picks up most
    electrical noise from other apartments, from me switching other equipment
    on/off , from upstairs laundromat etc.. The noise appears as horizontal
    lines of snow.

    The other problem is that my PC sound setup is also affected - I can hear a
    click at the same time I see the noise lines on the TV.

    I've tried surge suppressors, fancy powerboard but they don't really help
    and I don't have enough knowledge on this matter. If anyone can help I'd
    appreciate it.

    ** This is very common with indoor TV antennas - if there is no roof top
    one to use then its time to invest in a digital Set Top Box. DSE have a
    very good one for about $ 145.

    ** That is a harder one - usually the only complete cure is to fit
    suppression caps to the switches inside the offending appliances .

    A digital set top (DST) box wont help if the noise is RF spark related. DST
    boxes are great for low level reception issues but mine still stumbles
    whenever I turn on an adjacent light switch. But yes, only caps at the
    source of the noise will cure the RF interference issue. Older washing
    machines are a very likely culprit.
  4. Why do they call them apartments when they are not very far apart? They
    should call them closements.

    ** Yes and no.

    If the RF noise burst is intense, then the pic on a ( decent) STB will just
    momentarily freeze - this may easily go unnoticed by a viewer.

    However, the bright flash on the screen with analogue TV "bugs" some
    olk - massively.

    ** Agreed - plus fridges and fluoro lights.

    ** Cos they keep the occupants "apart " - silly.

    I have a DSE $148 STB and my aerial is sitting in my roof space.
    Will mounting the aerial on the roof stop/reduce interference from 240v
    being switched and interference from the electric trains?

    A mains line filter might be worth trying in case the crap is coming in that
