I think the topic is getting a bit off track. Hopefully this brief background will help clarify.
The radio is very easy to use when it is properly programmed.
The crew has crib sheets (procedures) to follow for a properly configured radio.
The current status is the radio is NOT properly configured. One of the fault signatures is that the preset memories appear to be non accessible (not much fun doing everything with the VFO only).
During the 45 minutes I have with a crew member over a year before their mission, manually configuration of all the specialty modes is not discussed.
Given the current state of the radio, I'm not even sure that the radio can support anything other than voice but I am investigating.

A very apropos comment. These astronauts are the most highly trained
process individuals. Operating and setting the radio should be a cake walk.
I am truly surprised that we make this out to be difficult (and I own a
D700). Forget sending a PC (one more thing to breakdown, store, etc.) and
let's prepare a crib sheet, coat it with a station-approved laminate, and
send it with the next upload. Print it in all languages for the astronauts.
Seems like we are making a truly simple task very complex.

likelihood of having a school contact fail due to human error.

And how was it before the "human error" ? I'm wondering why an
astronaut can not handle an amateur transceiver. If the user interface
is too complicate it would be a good idea to give him a dedicated
notebook so he can click in a menu for Packet, school contact, repeater,
SSTV aso. If this problem is not solved, it is fruitless to discuss about
new modes. My 2 cents about this theme.
