As with all HEO theories, we have to take this as one with a burden of
expenses. My idea of a baseline is also an AO-10 or 13 type bird.
Propulsion and getting a ride To the HEO orbit is very expensive. AMSAT,
without having help from other interested parties, cannot possibly meet
expenses on this. With a ride offer from one of the launch facilities,
Satellite enthusiasts could possibly raise enough money to get this to
happen. ITAR is not helping this AMSAT group bonding to give this a chance.
Please let your wishes in this direction be known to any AMSAT people. I
have been accused of having my own agenda for HEO birds. Remember, we
cannot possibly afford this (unless a rich uncle leaves us a sizable amount)
and this is why our officers want to stress the present usable LEO birds as
our foreseeable future. Have faith and maybe the status of launches will
change and all this will be a mute point.

Linear birds are a good idea, and the idea of creating an "off the shelf"
transponder package that university groups can install into their projects
has been discussed here before, to help that end. larger footprints would
be nice (and extremely useful in this part of the world), but the trick
there is getting the launch opportunities at an affordable price, since it
seems most affordable launch opportunities are to LEO. You can only place
your bird where the ride takes you, unless you add propulsion, which means
extra weight and complexity (meaning more cost, fewer launch opportunities
and higher risk of failure, and most likely fewer birds).
One of these days, I'll have a crack at the linear birds we have. I have
the gear, just have to get around to using it! :)
