As I understand it, they are asking you, me and all other hams to invest in
this equipment because they believe that in a few years' time S band will
be unusable for a downlink. In which case, our investment is already lost
for the purpose of Eagle and we should be grateful for the analysis that
made us aware of the fact. If the analysis is incorrect, I imagine the
designers would be happy to be proven wrong, given how much more experience
there is with S band in the satellite design community. The ppt file does
address the money issue to some extent, pointing out 9cm costs and such.

In either case, we will be able to use S band equipment in HEO on P3E and
SSETI ESEO, and I assume the dish and pointing equipment for 23cm could be
reused for 9cm. 

As to the question of the designers buying the equipment required, I
understand the plan with C-C rider and its replacement is for ground
stations to be developed in tandem with the bird. The designers will be all
the more on board if that's the case. If it's simply a question of who's
spending money to get this thing going, I have to say I believe the
designers are likely spending a few dimes more than you or I. 

I think it will all work out and we'll all get a chance to be on the air
when it flies.
