The moon is interfering with radio signals? Doesn't this only happen if the moon is literally blocking line of sight? It seems like being outside of earth's atmosphere and ionosphere would be the biggest benefit for radio.

The moon is basically a giant reflector for (many bands of) radio. The reason the US government funded so many radio telescope arrays was to monitor Soviet ballistic missile tests, by looking at signals reflected off the moon.

There's still a lot of rf noise that can penetrate that far. ~3,400km of solid rock is a much better attenuator.
