I have been listening several evenings now on 160M using my K3 in diversity
mode with the TX vertical array on one receiver and a full-wave horizontal
loop on the other. I have been struck by the often rapid change in the
signal as received on one antenna or the other. As sunrise on Amsterdam
approaches this shift becomes quite rapid, with the recovered signal
bouncing back and forth ear to ear. Early on, before I began listening in
diversity mode,I thought it was rapid QSB taking the signal down into the
noise but now realize that it is the angle of the arriving signal which is
rapidly changing over the path.
No wonder some of the guys have been having problems copying/working the
expedition on topband!
