I have encountered similar phenomenon while operating from large contest 
stations.  I did not need QSK to hear these echoes and I mostly noticed them on a 
40-50 degree azimuth from the NE U.S.  It happened most on 20 meters with 6-el 
yagi, rarely on 15 meters with a 5-el yagi; both were at 100' to 120' above 
ground.  Never heard it on 10.

It was not common, but happened often enough that I was not surprised when I 
heard it.
