When I lived in 4X I used to get up early before 20m was open and call CQ with QSK while rotating my beam. I would listen for the echo of my own signal coming all the way around the world. My theory was that the band must be open in the direction that the echo was strongest. But I never got a QSO that way. Now I think that the loud echo was due to some type of 'chordal propagation' and my signal was never coming down to earth in any populated place. Of course I could have worked another station nearby by that path.
