Given that It's easier to search in quieter wavelengths like 0.7 and 93 GHz. But is there anything on Earth 1) transmitting unique signals 2) in that range with 3) the kind of power that would survive the rigors of the journey through hundreds of light years? What is our interstellar beaming frequency? At what power? Why else would there be any signals between 0.7 and 93 that aren't -300dB down? Radio waves spread. And scatter. You're going to travel in the mountains in a remote region of a planet with no ionosphere. You want to eat your meals while listening to music. Do you take a shortwave radio or an FM radio? Absence of evidence is not evidence of absence. We're looking for the lost keys under the streetlight.
