seti is search only.
and we are sending out massive radiowave signals constantly and in all directions for more than a century now.
Are there any emitters that really cover "all directions"? There's infinitely many of them (directions), so pointed "beams" would cover virtually nothing at sufficiently large distances.
Yeah but we like to point our beams directly at solar systems that we believe could have planets with "life-supporting" conditions. Yeah that should turn out splendidly, like it did in the movie Battleship.
Actually, radiotelescopes are listen only.
There have been, I think 2, transmissions off the Arecibo array, really just special events/publicity stunts.
As far as anyone hearing us, I dunno man, that inverse square law is a killer.
