Would be true for omnidirectional transmission. Much much less for a directed transmission.

Given the detection of exoplanets of approximately Earth mass orbiting in habitable zones, that's rapidly become tenable.

Laser / maser signalling would probably be about the best we could do for now.

Hitting a fixed target, from light-years away, with a signal stronger than cosmic background? Pretty sure a world-class team could get PhDs just for the attempt.
