Also, AM signals don't escape into space like FM and TV signals do, they
just bounce around the ionosphere until they die out completely. We know
this as "skywave".
AM BCB (MW) signals do escape into space.. some at night, but most during
the day when the ionosphere is not reflecting most of them back to Earth.
Even at nights some signals strike the ionosphere at acute enough angles
that they will make it through.
I remember seeing an episode of Amazing Stories (TV show) back in the
80s where these teenage experimenters picked up TV signals from a planet
20 light years away. The aliens had recieved our TV signals during their
nascent radio era, and faithfully recreated the shows. Thus "I Love
Lucy" with little conehead like aliens whose language sounded like "rolf
rolf rolf".
I remember that AS episode too.. I miss that show. I have something like
three episodes somewhere around here on an old ßeta tape, will have to dig
them out sometime..
