this is the same experience I have. When the bird is over Africa with
no stations or max one station calling  in the whole passband, I can
hear my own signal usually down to 2 degrees elevation and that's with
2 x lindenblad antennas.
As soon as two or more stations with high power start uplinking, my
little signal disappears.
