Actually, I have not watched any television programmes on the

Believe that if you like.

As I implied, that rather depends on how far away one is from it and
so is able to isolate the signals from that particular piece of
equipment. I didn't say, but that is the case whether one is using
radio signals or (radio) signals on electrical wiring.

Believe that if you like. However, as I said, certain organisations
spend a lot of money preventing this from happening by things like
filters and screening. They are not wasting their time.

If you wish to believe differently then feel free to do so, but your
belief is demonstrably wrong. For a suitable fee I'm sure someone
could be persuaded to demonstrate this to you.
