Well I finally cracked it at 1531 UTC as I slept. It's not a good pic to be sure, but it's a dead straight pic inside the ISS with NA1SS on the bottom. Big band of noise due to QSB in the middle but never lost sync. It wasn't such a good pass either, about 7 deg az, so I'm nearly happy!!!

Now for the boys in South America. Good luck Daniel!!!!
