Joe,
Thanks! Signals from your QTH to receivers on the other side of the eclipse
path will have a broad peak in time, which accommodates long integration
times. Based on your comments below, we'll start with a (long) integration
time that accommodates the nominal amplitude rise/fall time associated with
your QTH. I'll send phase/amplitude plots when they're ready; thanks for
providing the signal!
73,
Jim AA5BW

Hi Jim,
Daytime receptions in Europe are not uncommon -- to the west they seem to be
quite rare. The night receptions were relatively close so its going to be a
long shot. Good luck and thanks for your interest.
