[sarex] No SSTV in VK/ZL?

Has anybody heard a peep in VK or ZL? Despite intensive efforts I've seen or heard nothing at all. Not even a peep on last night's overhead pass, not even the hint of a peep. I even left the rig and Computer on 24/7 last few days.

I thought I would hear *SOMETHING*, if not decode it!
