Well, depending on frequency you would still have some traversable effects regarding radio. You would have ground wave propagation at the minimum. unfortunately, most radio would be line of sight because of no atmosphere. Limited atmospherics would provide very restricted use on a multitude of frequencies mainly lower than 6 meter. If you wanted to communicate with the other side of the body, you would have to rely on a third entity like we do on here with the moon to bounce and receive. Aside from that option you would have little/no multi bounce
