The basic problem is that Amateurs want linear transponder satellites in orbits above 1400 km in order to provide reasonable DX opportunities and pass times greater than 20 minutes. But "cheap" launches only seem to be available for 500-800 km orbits, so we need to find a way to increase the orbit of say a triple-cubesat from 700 km to 1400 km using a non-combustive technology so as not to upset the cheap launch provider.
Providing the radio communications is by comparison a trival exercise it's finding a means (solar powered thrusters ?) to increase orbital height that's the tricky part.

Any interest by the Red Cross would not be in the satellite but in human volunteers that might come with it. Unfortunately, the LEO satellites that hams can afford generate little interest in this forum.

Rupert, I think that is a fair assumption on your part, but
only because the are
no new ideas being presented that have commercial
potential that can use
Amateur Radio as an inexpensive to proof of concept. In the present Amateur Radio community only Emergency
Communications is
getting the publicity. Perhaps FEMA or the Red Cross
might help pay for an
emergency communication satellite otherwise it is
LEO's forever!

Hallo all...
from a while I'm hearing about MANY different and
interesting satellite
solutions...
LEO, MEO, HEO, GEO... MOON !!!
The problem is only ONE !
Amateur radio community has no money for this project,
and will never
have!
Amsat & Co will never be able to collect
millions.... I red on this bb
that hams has no money for an expensive ground station...
then how can they
send many money to Amsat?
Public and private organizations all over the world
have not an high
consideration of hams, and will never invest founds
for them.
The conclusion is only ONE... we will never see a new
oscar satellite in
the sky (at least some student's cube).
Let's all dream together guys.
Best 73 Rupert
