I would like to first say that yes, many of these Cubesats projects do a
really poor job of providing information about themselves and they have a
lot of room for improvement.
Second that amateur bands are used not only for the fact that there are
already established ground stations, but because getting licensed on some
other piece of spectrum is a substantial investment of time and money, and
many of the student projects simply don't have excessive reserves of
either. Granted many of them would love to move off amateur bands, find a
little open spectrum in the GHz range where they can blast data down at
some incredible speed, in which case they could move more data in a few
seconds then they could collect in a day, which makes things many design
issues much easier. Alas when you tell a student to start filling out
paperwork that may get a response before they graduate, and until then
there isn't much they can do until they can lock down that parameter,
chances are if they are smart they will run off to do something else like
build a race car, or a robot and you loose someone else in the next
generation of rocket scientist.
Thirdly I have been reading the AMSAT-BB's for several months and I can see
why there wouldn't be many people working on CubeSats hanging around. In
order for anything productive to come of discussions like this, people from
the CubeSat community need to be more involved but they aren't going to be
inclined to do so when the conversations reads like dialog from "Grumpy Old
Men". Nano and Pico Satellites aren't a simple evolution
of existing technologies but a large paradigm shift, one which I don't
think anyone even now fully understands. When you don't have
thoughtful discussions between both sides issues don't get addressed, and
everyone's feelings get hurt. I would suggest using cubesat.org as a
