Before the advent of mandatory digital over-the-air TV, it was said
that the picture would be near perfect, and that there woudl be no
ghosts. Tonight I saw one, for a full half hour if the scene had the
right kind of lines, including vertical lines.

Please confirm that you do not drive a motor vehicle... If in fact you
do drive, please indicate what areas we should be on the watchout for
you.

I missed the original post, but the appearance of ghosts can
be caused by a limited bandwidth of the video circuit.

Ghosts can also be caused by improper termination of the
feed line from the antenna to the TV.
