Strongest radar we have ever made could do perhaps a few hundred light years? The Milky Way is 100,000 light years across and there are only about 59,000 stars visible with a telescope within 100 light years of earth. I think it would take a very charitable reading of the Drake equation to believe our signals even met intelligent life capable of receiving them.

Joe Scott did a video on this last year: https://youtu.be/ISXbTBKl4aE

He's just a science enthusiast, but it touches all the points it needs to.

Love Joe Scott. He's one of the few channels I watch.

Joe Scott is like listening to ChatGPT. In most videos you'll find confidently wrong stuff like "we communicate mostly through satellites these days ... they're only having to go up you know 100 or so kilometers."

Perhaps if some advanced civilization were able to modulate radio pulsars. But it's not like we're monitoring across a wide bandwidth, so they'd need to transmit at the specific narrow band that we listen to. SETI is fun to think about and experiment with but it always strikes me as bit of a fool's errand.
