There's no need to "try". We've been radiating radio and TV out into the galaxy at
thousands of different frequencies for a little over a hundred years now, announcing
to anybody that's listening that we are here.
It's estimated that there are roughly 500 G-type stars ... the same type as our sun,
and the type thought to have the best chance of life somewhere in its planetary
system ... within 100 light years of us. So if there's anybody on any planets around any
of those stars, our radio transmissions have reached them by now, and they may be
sitting up nights in their observatories watching "I Love Lucy" through their radio
telescopes. The mind boggles!
