Do we know what we did with radio when it was first discovered to know what it would be like if it bounced back to us? Or would it not have been strong enough?

Quadratic decay plus reflection losses plus only a fraction of the emitted signal being reflected: pretty much guarantees we wouldn’t be picking it.
