What happened to the vans with antennae that scanned for operating TVs (there’s an IF oscillator in there I guess) to find unlicensed receivers?

  The BBC has never offered any proof or explanation of how they worked, and there is some suspicion that they are fakes used for their psychological effect.

    You can absolutely listen for the TV heterodyne leakage.
