It’s unlikely that a detectable signal from Earth has penetrated into space much further than about 0.6c-yr. That’s not “deep space.”
The Galaxy is thought to be about 1000 light years thick and 160,000 light years in diameter so, yeah... Our transmissions are not that far into space to have attracted much attention.
Heck, the gravitational effect of our sun reaches out only about two light years and Voyager, with its fancy plaque, has only just reached the edge of the solar system where sunlight is thought to penetrate.
