TV detector vans
are these still in use?
can they pin point a tv set through sumbodys walls or is it all just one big list of homes without a licence
just reading sumthing about the vans having equipment which detects the magnetic field which shows around a tv screen
wtf is all this about??
anybody know if the vans can detect between colour screen magnetic fields and black and white screens

used to work with someone who did this for a living and apparently they could only detect crt's (cathode ray tubes) and even then not as accurately as they would have you beleive in the ad's. however the new plasma and lcd tv's they cannot detect however i think they rather u do not know this

Yes they have detector vans. And it is equipped with one of the most advanced type of TV detectors known. As in the bloke behind the wheel, he'll look for the SKY dish, failing that have a peek through the windows, lol

when your tv is in use, it converts one signal into another, but in order for the laws of physics to be obeyed it must also give off the opposite signal to what it is displaying. sort of like, if you give it a signal of 10, and the picture is 4, it must transmit the six somewhere as radio waves. this is a very simple example, and is one of the reasons why mobile phones aren't supposed to be used on forecourts, as the signal they give off can create a current and therefore sparks in nearby metals.

anybody running with a black and white licence then??
must be quite hard to detect diffrent sets in a block of apartments
i opend the mailbox for my new pad and found 2 letters from them about the TVL and theres not even any dam furniture in there yet
as a bonus, the entire building has the basic sky package wired up for each apartment as part of the deal, which was a bit of a suprise
just need to put a receaver in there (got one 
)

the same thing causes claymore mines to go off, thats why radios can't be used within 100m of one.

i know that, i only said it was theoretical, and the static thing is right, especially off women getting in and out of their cars.
that is why you should earth yourself on a piece of metal before you open the cap, in case your spark catches some of the vapour.

this is all going technical
there is a lot of mystery surounding these vans, i always thought they just listed all address`s without a TVL
i never relised that a tv would actualy broadcast sumthing outwards which could be picked up outside a building, sounds like madness

ok olly, i agree, i don't turn my mobile off at the pumps like everyone else, but i'm just saying it happens and is cited as a reason why you should turn it off.
as you said the static thing is the chief cause.
sorry.

As they have no powers of access, when they knock on the door, you say "I have no TV and shut the door". Assuming they can't see the actual TV from outside, there is nothing more they can do. There is a website and somebodies ongoing fight with the TV bods, IIRC it's Capita (again). I'll see if I can dig the link out.

do u know how difficult it is for your average 3.62 v battery to produce an arc seeing electricity usually needs a 10000v to arc an inch through air
