70 cms is actually the preferred uplink for a number of reasons,
including less path loss on the downlink, less ground based QRM, and
easier Doppler management. This was part of my lessons learned at LEO
paper from the Symposium.
I'm aware that the FCC and DOD has restricted some repeaters that were
causing interference to PAVE PAWS, but I'm not convinced your blanket
statement about 70cms being completely off limits is accurate at all.
There is plenty of activity on AO-7 and VO-52, and 432 terrestrial from
that area now even. While you may not be able to transmit more than 50
watts without the waiver, or below 15? degrees, thats about 10 times
more than I'd expect necessary for this new satellite.
Can you point me towards more information on this prohibition?
