During recent EME tests in 2010 with PA2DW, I was faced to very strange signals next to the bounced EME signal. It turned out to be a direct signal path and a signal path caused by airplane scatter. See below at 1500Hz the bounced EME signal of PA2DW sending RRR's in JT65 mode. At 2300Hz the direct path and the swallow lines caused by airplane scatter.
