They wouldn’t receive the signal if they’re at the same tech level. Radiation from our communication tapers off well below background levels at 100ly. Maybe if they got lucky and had very, very sensitive instruments aimed our way at the right moment, they might detect something that didn’t fit background, but our power output pales in comparison to the cosmos.

Just look at all the tricks scientists have to pull to communicate with Voyager, and it’s not even outside of the frigging solar system, yet!
