I think our first radio signals were send around the very end of the 19th century. They would have traveled around 125ly. Don't know if the signals had enough amplitude and frequency to even leave the atmosphere though.

There are quite a few stars in a 125ly sphere already, but the center of our galaxy alone is 25k ly away. So we wouldn't be know to too many neighbors yet.
