I think it's possible to do much better than 1.5 light years, if you can

ways to recover periodic signals/signals with structure that have been
corrupted by noise.

So even if we could do 3 light years, there's still nothing much within
that radius that we could expect to communicate with. Why did all that
effort go into SETI, then? Surely all the nerds that ventured into that,
or granted the SETI nerds spare time on their idling computers to analyse
the data obtained from the world's radio telescopes must have known they
were wasting their time!
