I remember reading about that some time ago (decades?), and wondering since
then how much that whole thing had gotten messed up since computer monitors
had come into the picture.
The detector vans looked for the local oscillator radiation from the tuner,
uhf for the past 20 years or so, using a pair of rotateable horn antennas
to get a precise fix on the set. I don't think they use them any more,
I've not seen one for years.
