Let me address this one paragraph.

The AMSAT engineering task force was involved with a detailed proposal put
together by Tom Clark for a GEO rideshare package last year. Unfortunately
that did not work out, but it did lead us to develop a modular construction
strategy where we may be able to quickly respond to some opportunity. Any
effort put into a LEO package has direct applications to a HEO spacecraft,
or educational aspects, or usually both.

Let me remind you that AMSAT-DL has a 90% constructed HEO waiting for a way
to pay for a launch. Until they find and pay for a launch, they don't have a
viable HEO program either. Unfortunately, and this is my opinion, I believe
the size and shape of that HEO severely restricts how it can get to orbit.
I'm not criticizing the German effort, I support it. I merely am pointing
out a problem that we must avoid. We do indeed learn as we go.
As an example of the issue: Say we have our physical Eagle spacecraft which
has been through 3 or 4 iterations, but damn it we built it anyways. Let's
say we replicated AO-13, like P3E. So we manage to find a few million to
launch as a secondary and we decide ULA is the launch agency. Take a look at
Would our spacecraft fit in anything other than the largest, most expensive
space? Did we design it to take the G forces of launch while stowed
vertically, horizontally, or inverted? What seperation system did we build
into the spacecraft? Does it even fit in the space allowed? This problem is
present no matter the launch vehicle or agency.
Many of us have come to the conclusion that it is a bit fruitless to build a
spacecraft without knowing the size, shape and orientation of the ride we
are taking to orbit. That's why we are developing a modular approach to be
able to react quickly, with space proven hardware even, to a short fuse
opportunity to LEO, HEO, MEO, or GEO.

AMSAT-BB is a giant discussion group. Talk about related items as much as
you want. Identify some launch or funding opportunities. Write a paper for
the symposium. If your ideas are good, you do what you say you will do, and
you are a team player, sooner or later you will find yourself asked to
participate at higher and higher levels. Listen, I own stock in Ford, drive
three different Ford vehicles, but I know that I'm not going to get to
design the next F150 just because I had a comment on an email list. I'm not
trying to be flippant, I just am pointing out that you have to actively
prove yourself to be part of that level of volunteering for AMSAT. I didn't
go from suggesting ideas on the -bb right to the BOD or a VP slot. I busted
tail at hamfests for years, hawking books and t-shirts and doing the Arrow
dance. We always need active Area Coordinators. I didn't like what I saw
happening with the first version of the Echo Ops group, and got volunteered
after showing up at a BOD meeting and making a strong argument for a better
way. For two years I helped with scheduling and events, and when Mike
resigned I was asked to do the job of VP Ops. I did that for a time before
deciding to run for the BOD. I've picked up other responsibilities here and
there when no one else would do them or when I was the best qualified (I
think that's happened once!). That is how you make things happen in AMSAT,
and that is the type of volunteers we need more of.
Nothing in AMSAT is well hid. Something may be lost from time to time, but
never hid. To be hid means it was done intentionally. Sometimes there just
isn't enough volunteers to go around.
Enough for tonight. I hope I've managed to express at least some of my views
on the topic. What I've said may not match up 100% with AMSAT policy, but
there it is.
