Heard a earth/sat/sat/earth signal this morning. at 1550 earth heard YL??? in ko26 in qso with SM7BHE via AO29 on 435860 on CW. Heard both sides of the CW QSO didn't pick up the pencil fast enough to record the YL full call. It had to be AO-07 to FO-29 link. Been a lot of years since I have heard a double link.
