If an extraterrestrial civilization had a SETI project similar to Project Phoenix, could they hear Earth?
In general, no. Most earthly transmitters are too weak to be detectable by Phoenix-type equipment at the distance of even the nearest star. The exceptions are some high-powered radars and the Arecibo broadcast of 1974 (which lasted for only three minutes). To detect “leakage” radiation similar to our own will require instruments that are many times more sensitive than what we now have.
