The only possible practical SSTV uplink scenarios that I can
think of are:
1) Full duplex repeater so everyone can hear whats going on the
2) Completely secret uplink for one station per orbit (assigned
like a school contact)

I don't see any possibility at all of a full 40 seconds of clear
uplink otherwise...

Good luck.
