This is (was) true, but only if the distant end has an identical or better aricebo pointed at us… …several (or several thousand) years into the future. And even then tracking difficulties and the sheer vastness of space would make the chances of success near-zero. Due to having a fixed dish with only a movable antenna feed the available look angles of aricebo are limited. In all likelihood the aliens looking for us have a mega-aricebo in a random valley that is perfectly capable of receiving our signals but it is positioned one degree off-axis from the angle needed to receive us and they are as puzzled as we are as to why they are not hearing anything either.
