Default Re: TV Detector Vans

Of course, if you knew what IF the detector vans used (I'm presuming, not unreasonably, that they were superhets) you could, with a sensitive enough receiver, build a TV detector van detector; which would pick up the detector van's local oscillator and automatically switch off the TV as soon as a TV detector van was detected .....

Having a free choice of IF, you'd not be quite so vulnerable to a TV detector van detector detector!

Why wasn't a smartcard reader mandated for all digital receivers, whether combined or separate, from the outset? Then the BBC could have just issued viewing cards for their programmes, and had automatic licence fee enforcement with no need for heavy-handed tactics.
