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 uplink 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. Bob

I believe this would be impractical. There are a number of
satellite
operators that don't read these messages. Of those that do, there are bound to be some who don't wish to comply with the rules for one
reason or
another. If only a hand-full don't cooperate the resulting pandemonium would encourage those that do cooperate to abandon the program or
give up.
If you've ever been in a DX pileup, you'll know what I'm talking about.

Hi folks, one member just reminded me about what is the
chance one station
uplinking one picture uniterrupted? Maybe we could cordinate here and use are calls as a your
turn my turn
such as abzzz goes first as his starts with A, or use the last
letter of the
call such as kc8gkf and everyone with f in there call (last
letter) thats there
day to xmit up. something like that I think we could work
out. That would
cut down on the stations trying to xmit up. Or someone
could pass out
times to the users (get a list here) to xmit up. Anyother ideas?
