Answer 2

there are infinite frequencies (including all radio signals, electrical, etc.)the radio alone has quite a few hundred thousand.
just many we don't know of. (it is technically infinite though, because a signal that covers lets say 101.9 to 102
has all the 101.91 and 101.911111111111111111111111111
as well.
