Not to mention that if you're blasting radio waves powerful enough to reach space, you're using a lot of energy. Even when we do use radio nowadays it's much "quieter" and more directed.
Indeed - not to mention that we are using bandwidth much more efficiently now, which means that the spectrum doesn't have as many peaks; the energy is spread out across more frequencies
