[amsat-bb] Eshail2 inverting yes or no?

While actually building equipment for Eshail2 (soldering iron was smoking ;-) I had a local QSO about Eshail2.

Suddenly someone asked if I knew if the transponder (up-/downlink) setup was inverted or non-inverted.

I remember having been told that the setup will be non-inverted, but can't find information/verification on this subject.

Personally I think it would be ideal if the transponder setup is non-inverting, so (let's say) 2.4G USB up --> 10.5G USB down.

Anyone who can clarify this?
