Radio Transmissions

Can someone refresh my memory on wave interference? I've been out of
school too long to remember any details.

As I recall, at least all similar waves interfer with each other to some
degree. How similar in frequency and type do those waves have to be to
cause some interference? How does that afect what you would be able to
detect at one light year? Would those signals retain enough of their
original form to be easly detected?

We do know that we are still able to pick out the signals from our most
distant still working probes because of receiver improvements. However
that is a weak transmission, and it is the only signal in that area.
