I heard the same thing on AO-85 recently. I would hear
myself coming back from the satellite in real time (plus
a slight delay for my SDR receiver & software), and then
hear it again 2-3 seconds later. It seemed more like some
station was retransmitting whatever it heard from AO-85,
which happened to be my voice at that moment. I did not
write down when this happened, but I have recordings of
all AO-85 passes I worked, so I can go back and pinpoint
when this happened. I might do this later tonight between
some passes while staying up late, or tomorrow. If someone
is really bored and looking for stuff to do, feel free to
visit my Dropbox space at http://dropbox.wd9ewk.net/ and
take a listen to my recordings. :-)
