The first commercial radio station went on the air in 1920. So, that footprint is more like a bubble 95 light years across. Call it 100, just for sake of rounding the number.
We don't have an accurate measure, but by star density estimates, there's something like 10,000 to 14,000 stars in that sphere.
Our Sun is spectral type G - there are 511 stars of this type in that sphere.
About 22% of those stars probably have Earth-sized planets in their habitable zones. That makes for about 100 potential worlds to hear us, before we even start to consider anything particularly exotic.
I was going from the point of the first intelligent radio broadcasts, which would have been radio telegraphy, to give it the best possible chance. We're still talking about short odds and a rather massive time scale, with us only having been here for a relative instant.
